The present disclosure is directed generally to multi-layered pipes, methods of forming multi-layered pipes, and machines for forming multi-layered pipes. The multi-layered pipes may be used in the hydrocarbon industry, such as in the extraction and/or transportation of hydrocarbons.
In the hydrocarbon (oil and gas) industry, metal pipes, or pipelines, are used in a variety of situations, from the drilling and extraction (production) of hydrocarbons to the transportation of hydrocarbons. For example, in the production of hydrocarbons, metal pipes may be positioned within wellbores for the extraction of hydrocarbons from a subterranean reservoir. Additionally or alternatively, metal pipes may be positioned within wellbores for the delivery of fluids to a subterranean reservoir, for example, to displace the hydrocarbons being extracted from the subterranean reservoir. Extraction sites may be on land and/or offshore. Once extracted, the hydrocarbons may be transported over distances—sometimes very long distance—through pipes. Such pipes used to transport hydrocarbons, which may be referred to as pipelines due to their length, may be subterranean, may be above-the-ground, and/or may be underwater.
Long pipes, or pipelines, used in the hydrocarbon industry, whether installed subterranean, aboveground, and/or underwater, are typically first manufactured in relatively short segments (e.g., 5-25 meters in length) at a manufacturing facility, which may be hundreds or thousands of kilometers, or even continents, away from an eventual installation site for the pipe, or pipeline, such as a hydrocarbon production or transportation site. These segments are then transported to the installation site, for example, by truck, rail, and/or ship, and typically are then manually welded together on-site to form a long pipeline. In some situations, the final pipeline may be hundreds, or even thousands, of kilometers long, with such pipelines requiring 40-200 or more separately welded joints per kilometer of length, often amounting to tens of thousands of individual welded joints for a single pipeline. The transportation and welding requirements may be exacerbated when the pipes are to be transported to and joined to form a pipeline in arctic and other regions where environmental conditions limit the time periods in which these operations may be performed. Added difficulties of welding and pipe joint transportation may occur when large-diameter pipes (such as pipes having diameters of at least 0.5 meters) or thick wall pipes (such as pipes having walls with thicknesses of at least 2 cm) are required.
Extruded plastic pipes and fiber-wrapped pipes have been proposed as methods to continuously form pipe, with illustrative examples of such pipes and formation methods being disclosed in U.S. Pat. Nos. 2,377,908 and 3,948,292. However, extruded pipes are typically not suitable for high pressure. Fiber-wrapped pipes are complex to manufacture, especially outside of a specialty construction facility. Moreover, both types of pipe are difficult join up with existing metal pipe segments since neither plastic pipes nor fiber-wrapped pipes are weldable. Also, quality assurance may be difficult using conventional and/or suitable in-field methods, which tend to be designed for use with metal pipes. Additionally, fiber-winding methods are generally unwieldy for large diameter, long pipe segments since the winding equipment needs to rotate around the pipe segment or the pipe segment itself needs to be rotated.
Methods have been disclosed in the past for making multilayer-walled pipes and pressure vessels. An early example is disclosed in U.S. Pat. No. 2,072,273, which describes a method of making a pressure vessel shell. The method includes forming a plurality of metal sheets; superimposing one sheet upon the other; applying substantially uniform pressure both externally and internally of the superimposed sheets to hold them tightly together; and joining the sheets together along their respective seams while such pressure is maintained. Another example is disclosed in U.S. Pat. No. 1,925,118, which describes a pressure vessel having side walls that comprise a plurality of concentric tubular members that form a laminated structure. The individual members of the pressure vessel are constituted by a sheet metal blank that is shaped into tubular form and fused at its meeting edges with the adjacent tubular member. Additional illustrative, non-exclusive examples of laminated metallic pipe and pressure vessel constructions are disclosed in U.S. Pat. Nos. 3,149,513, 3,610,290, 4,244,482, 5,097,585, 5,755,266, 2,209,402, and 3,425,380.
The present disclosure is directed to multi-layered pipes, to methods of forming the same, and to machines for forming the same. The multi-layered pipes may be used in the hydrocarbon industry, such as in the extraction and/or transportation of hydrocarbons. Multi-layered pipes according to the present disclosure include at least an inner metal tube and a second metal tube formed around the inner metal tube. Multi-layered pipes according to the present disclosure optionally may include at least a third metal tube formed around the second metal tube, and further optionally may include at least a fourth (or more) metal tube formed around the third metal tube.
Machines according to the present disclosure include an inner-tube forming device positioned to receive a first metal stock and configured to form an inner metal tube from the first metal stock, a second-tube forming device positioned to receive a second metal stock and configured to form a second metal tube around the inner metal tube from the second metal stock, and a control system configured to simultaneously feed the first metal stock to the inner-tube forming device and feed the second metal stock to the second-tube forming device. Machines according to the present disclosure optionally may include a third-tube forming device positioned to receive a third metal stock and configured to form a third metal tube around the second metal tube from the third metal stock, and further optionally may include a fourth-tube forming device positioned to receive at least a fourth metal stock and configured to form at least a fourth metal tube around the third metal tube from the fourth metal stock. In such embodiments, the control system may be configured to simultaneously form the third metal stock to the third-tube forming device, and optionally the fourth metal stock to the fourth-tube forming device. In some embodiments, the tube forming devices are coupled to a vehicle, which may be operated proximate to an installation site for the multi-layered pipe, such as a hydrocarbon extraction or transportation site.
Methods according to the present disclosure include forming an inner metal tube from a first metal stock, and while forming the inner metal tube, forming a second metal tube around the inner tube from a second metal stock. The inner metal tube and the second metal tube are thus formed simultaneously. In some methods according to the present disclosure, the methods include simultaneously forming at least a third metal tube, and further optionally at least a fourth metal tube, around the second metal tube while forming the inner and second metal tubes. In some methods, sheet metal or other metal stock is bent to form the metal tubes with seams, and the seams are welded while the tubes are being formed. In some methods, the welds are inspected while the tubes are being formed. Some methods may be performed proximate to an installation site for the multi-layered pipe, such as a hydrocarbon extraction or transportation site. Some methods are performed on a vehicle and proximate to an installation site.
Machines and methods according to the present disclosure may draw the metal stocks from the same or different metal supplies, and optionally may draw the metal stocks from one or more shared, or common supplies, or further optionally may draw each metal stock from a different, respective metal supply.
Of particular interest, although not a requirement of the present disclosure, is the application of the multi-layered pipes, machines, and methods of the present disclosure to improve constructability and to reduce the cost of large-diameter pipes and of thick-walled pipes suitable for long-distance, high-pressure transport of hydrocarbons.
The present disclosure is directed to multi-layered pipes, for use such as in the extraction and/or transportation of hydrocarbons, to methods of forming such multi-layered pipes, and to machines for forming such multi-layered pipes.

For example, multi-layered pipes 200 according to the present disclosure may be installed, or positioned, within a wellbore 22, for example, for the extraction of hydrocarbons from a subterranean hydrocarbon reservoir 24 and/or for the delivery of fluids to a subterranean hydrocarbon reservoir to displace the hydrocarbons being extracted. Accordingly, the multiple dashed lead lines for reference numeral 200 associated with wellbores 22, schematically indicate that more than one multi-layered pipe 200 according to the present disclosure may be installed, or positioned, within a single wellbore 22. As used herein, “installation site” refers to a site, or position, at which, or at least near or proximate to, a multi-layered pipe 200 according to the present disclosure will be positioned for use, for example, in the production and/or transportation of hydrocarbons. Accordingly, this term is not intended to refer to a manufacturing facility that is remote from the site where a multi-layered pipe 200 will be ultimately used in the production and/or transportation of hydrocarbons.
Additional illustrative, non-exclusive examples of installation sites for multi-layered pipes 200 according to the present disclosure include sites associated with the transportation of hydrocarbons. As illustrative, non-exclusive examples,

Second-tube forming device 54 may form second metal tube 68 around inner metal tube 62 in a tight relationship, such as illustrated in the illustrative, non-exclusive example of a multi-layered pipe 200 of
Inner-tube forming device 52 and second-tube forming device 54, and other tube forming devices according to the present disclosure, any and/or all of which may be referred to herein as a, or as an Nth, tube-forming device, may take any suitable form or configuration for forming, constructing, bending, and/or extruding a tube from a metal stock, with such tube being suitable as a layer of a multi-layered pipe 200 according to the present disclosure. For example, a tube-forming device according to the present disclosure may include at least one die, such as may be configured to receive sheet metal and bend the sheet metal into a tube. In some embodiments, the sheet metal is as wide as the circumference of the tube it is to be formed into. In other embodiments, the sheet metal is essentially as wide as the circumference of the tube it is formed into, minus any gap or plus any overlap appropriate for seam welds.
Although any suitable size, type, and/or configuration of die may be utilized, illustrative, non-exclusive examples of suitable dies include fixed and rolling dies. An illustrative, non-exclusive example of a suitable die is disclosed in U.S. Pat. No. 611,222, the disclosure of which is hereby incorporated by reference. Other illustrative, non-exclusive examples of methods for bending sheet metal into tubes, including suitable dies for use in such bending processes, are disclosed in U.S. Pat. Nos. 1,665,851, 1,915,257, 1,954,160, 2,803,730, 3,069,763, and 3,085,146, and in German Patent No. DE3044003, the complete disclosures of which are hereby incorporated by reference.
The inner-tube forming device may include one or more inner-tube dies 74, the second-tube forming device may include one or more second-tube dies 76, and an optional Nth tube-forming device may include one or more Nth-tube dies. Furthermore, methods according to the present disclosure may be described as including the feeding of sheet metal or other metal stock through an inner-tube die, a second-tube die, and/or an Nth-tube die. As used herein, references to an Nth tube-forming device, Nth-tube die, Nth-tube, etc. refer to at least an optional third, fourth, or subsequent such device, die tube, etc., with N being an integer greater than 2. It is within the scope of the present disclosure that the inner metal tube, inner-tube forming device, etc. alternatively or additionally may be referred to as a first metal tube, a first-tube forming device, etc. Likewise, for any multi-layered pipe 200 according to the present disclosure, the pipe will have an outer tube, which may additionally or alternatively be referred to as the outermost tube and/or the exterior tube, and this outer tube may be the second tube, the third tube, the fourth tube, etc., depending on the number of tubes, or layers of tubes, that are formed by machines and/or methods according to the present disclosure when forming a particular multi-layer pipe 200. When a multi-layer pipe 200 according to the present disclosure includes three or more metal tubes, the multi-layer pipe may additionally or alternatively be described as including at least one internal, or intermediate, metal tube, that is positioned between the first, or inner, metal tube, and the Nth, or outer, metal tube.
Other configurations of tube-forming devices are also within the scope of the present disclosure and may be incorporated into machines 50 according to the present disclosure and/or be used with methods according to the present disclosure. For example, as another illustrative, non-exclusive example, tube-forming devices according to the present disclosure may include specially configured rollers for bending sheet metal or other metal stock into a tube, an example of which is disclosed in U.S. Pat. No. 1,665,851, the disclosure of which is hereby incorporated by reference. Although typically configured to form cylindrical tubes, it is within the scope of the present disclosure that tube-forming devices according to the present disclosure may be configured to form any suitable cross-sectional shape of tubes, and tube-forming devices according to the present disclosure are not limited to forming tubes having circular cross-sections. Illustrative, non-exclusive examples of other suitable cross-sectional shapes include generally rectangular, polygonal, elliptical, ovular, and other shapes.
Examples of tube-forming devices that bend sheet metal or other metal stock into respective tubes of a multi-layered pipe 200 according to the present disclosure, whether including die(s), roller(s), and/or other structure, may be described as being configured to bend the sheet metal or other metal stock to form at least one seam. For example, inner-tube forming device 52 may be configured to bend sheet metal to define at least one inner-tube seam 70, as illustrated in the illustrative, non-exclusive examples of multi-layered pipes 200 of
Additionally or alternatively, a tube-forming device may be configured to bend more than one sheet, or stock metal, and therefore to define more than one seam. This is schematically illustrated in
The present disclosure is not limited to tube-forming devices forming tubes from one or two stocks of sheet metal or other metal stock and any suitable number of metal stocks may be used, including one, two, three, and greater than three stocks of the same or different sheet metal or other metal stocks. When the three equal-sized sections are utilized, each section may define, or form, approximately 120° of the circumference of the corresponding tube, when four equal-sized sections are utilized, each section may define, or form, approximately 90° of the circumference of the corresponding tube, etc. When a tube of a multi-layered pipe is formed from two or more sections that are bent from metal stock, or sheet metal stock, such as described herein, it is within the scope of the present disclosure that the sections may have different relative sizes, and thus that each section may define, or form, a different percentage, or portion of the circumference of a corresponding tube.
Additionally or alternatively, as graphically depicted in the illustrative, non-exclusive examples of multi-layered pipes 200 illustrated in
Control system 56 is provided and configured at least to simultaneously feed first metal stock 58 to inner-tube forming device 52 and feed second metal stock 64 to second-tube forming device 54. Accordingly, a method according to the present disclosure for forming a multi-layered pipe 200 according to the present disclosure may be described as forming an inner metal tube from a first metal stock fed from a supply, such as a first metal supply, and while forming the inner metal tube, forming a second metal tube around the inner metal tube from a second metal stock fed from a supply, such as a second metal supply. That is, as first metal stock is being fed to the inner-tube forming device, the second metal stock is being fed to the second-tube forming device, and although spaced apart in relative distance, as schematically illustrated in
Stated differently, and in terms of relative longitudinal sections of a multi-layered pipe 200, a method according to the present disclosure may be described as forming the inner metal tube of a first longitudinal section, and then after forming the inner metal tube of the first longitudinal section, forming the second metal tube of the first longitudinal section around the inner metal tube of the first longitudinal section. Similarly, such a method may further include after forming the inner metal tube of the first longitudinal section, forming the inner metal tube of a second longitudinal section, with the second longitudinal section being upstream, or toward the metal supply, or left in the schematic illustration of
Therefore, while a given cross-section of a multi-layered pipe 200 according to the present disclosure includes at least an inner metal tube cross-section and a second metal tube cross-section, such cross-sections were not formed, or bent, simultaneously by respective tube-forming devices; however, after a start-up period of a machine 50 according to the present disclosure, a section of the inner metal tube is formed simultaneously with another section of the second metal tube that is longitudinally spaced from the section of the inner metal tube being formed, or bent. Furthermore, a section of an (N−1)th metal tube is formed simultaneously with another section of an Nth metal tube that is longitudinally spaced from the second of the (N−1)th metal tube being formed, or bent.

As an illustrative, non-exclusive example, machines 50 according to the present disclosure may include a feeding device 77 that is positioned and configured to feed metal stock from the metal supply, or respective metal supplies, to the tube-forming devices. The feeding device 77, when present, may be described as a component of control system 56, in so far as the feeding device implements simultaneous feeding of the first metal stock to the inner-tube forming device and feeding of the second metal stock to the second-tube forming device. Additionally or alternatively, the control system may control the feeding device such that the first metal stock is fed to the inner-tube forming device while the second metal stock is fed to the second-tube forming device and while an Nth metal stock is fed to an Nth-tube forming device.
A metal supply 59, such as first metal supply 60, second metal supply 66, and/or other metal supplies according to the present disclosure, any and all of which may be referred to herein as a, or as an Nth, metal supply, may take any suitable form or configuration. For example, a metal supply may include at least one supply of sheet metal. Such sheet metal may be provided in stacks or other configurations of individual sheets of sheet metal.

Some such welding processes may include utilizing flames, electrical arcs, electrical resistive heating, electrical induction heating, friction, electron beams, and/or lasers to form the weld. Moreover, the welding process may or may not utilize additional material (e.g., consumable welding rods) to form the weld. In some embodiments, tube joining devices according to the present disclosure may be described as being configured to weld at least one seam to form at least one seal, or weld, for a respective metal tube. Furthermore, as illustrated in
When machines 50 according to the present disclosure include one or more tube-joining devices, control system 56 may be configured so that the inner-tube joining device forms at least one inner-tube seal 82 while the first metal stock is being fed to the inner-tube forming device, so that the second-tube joining device forms the at least one second-tube seal while the second metal stock is being fed to the second-tube forming device, and so forth. That is, as discussed herein, the control system may be configured so that various operations of machines 50 are performed simultaneously while the various metal stocks are being fed, while the various tubes are being formed, etc., all for an efficient and convenient formation of a multi-layered pipe 200 according to the present disclosure.
Machines 50 according to the present disclosure may also (but are not required to) further include and/or be used with an inner-tube-seal inspecting device 86 and a second-tube-seal inspecting device 88.

Accordingly, a method according to the present disclosure may be described as including, while forming the inner metal tube, inspecting the inner-tube seal, inspecting the second-tube seal, and so forth. As illustrated in
Illustrative, non-exclusive examples of tube-seal inspecting devices according to the present disclosure include (but are not limited to) radiographic inspection devices, magnetic particle inspection devices, liquid penetrant inspection devices, and ultrasonic inspection devices. Additionally or alternatively, seals may be inspected visually by a person (i.e., manually or visually), and a separate device is not necessarily required to all embodiments of machines 50 according to the present disclosure.
When machines 50 according to the present disclosure include one or more inspecting devices, control system 56 may be configured so that the inner-tube-sealing inspecting device inspects the at least one inner-tube seal for quality while the first metal stock is being fed to the inner-tube forming device so that the second-tube-seal inspecting device inspects the at least one second-tube seal for quality while the second metal stock is being fed to the second-tube forming device, and so forth.
Machines 50 according to the present disclosure may also (but are not required to) further include and/or be used with one or more coating devices 90, such as may be configured to coat, spray, apply, or otherwise deposit a material on one or more of the metal stocks being fed to the tube forming devices. For example, in the example of metal stock being in the form of sheet metal, a material may be deposited by a coating device onto one or both sides of the sheet metal. As schematically indicated in
Additionally or alternatively, machines 50 according to the present disclosure may include one or more coating devices that are positioned and configured to coat, spray, apply, or otherwise deposit a material on one or more of the inside and the outside of a metal tube having been formed by a tube-forming device. Accordingly, as schematically illustrated in

The schematic illustration of the illustrative, non-exclusive examples of multi-layered pipes 200 of
The various components of machines 50 according to the present disclosure may (but are not required to) be coupled to a common object 98, an illustrative, non-exclusive example of which includes a vehicle 102. For example, the vehicle may be a land-based vehicle, such as a truck, rail-car, or other vehicle configured to facilitate transport of the machine from one land location to another, and more specifically from one multi-layered pipe installation site to another. Additionally or alternatively, the vehicle may be a marine-based vehicle, such as a ship, barge, or other boat configured to facilitate transport of the machine from one marine location to another, and more specifically from one multi-layered pipe installation site to another. Vehicles 102 according to the present disclosure may be considered a component of a machine 50 according to the present disclosure. Additionally or alternatively, a machine 50 may be coupled, and in some embodiments removably coupled, to a vehicle. As schematically indicated by an arrow in
In some embodiments, although not required, control system 56 may be configured so that vehicle 102, when present, translates relative to a ground surface and so that the multi-layered pipe 200 being formed by machine 50 is fed from the vehicle as it is being formed. Accordingly, as the vehicle travels relative to a ground surface, such as at an installation site, or at least adjacent to an installation site, the multi-layered pipe will be deposited in a desired location while the multi-layered pipe is being formed. Additionally or alternatively, the control system may be configured so that a rate at which the vehicle translates relative to the ground surface is equal to a rate at which the multi-layered pipe is fed from the vehicle so that the multi-layered pipe is positioned on the ground surface and at least initially does not translate relative to the ground surface. Such a configuration is not limited to land-based vehicles and also may be implemented in conjunction with marine-based vehicles, in which a multi-layered pipe is being positioned at an offshore installation site.
As mentioned, machines 50 according to the present disclosure include at least inner-tube forming device 52 and second-tube forming device 54, but may further include additional forming devices and related optional components. Accordingly,
Multi-layered pipes 200 according to the present disclosure may be formed in a variety of suitable sizes and lengths and having a variety of suitable properties, including formed with a variety of suitable sizes and properties of metal tubes. As illustrative, non-exclusive examples, a multi-layered pipe 200 according to the present disclosure may (but is not required to) have an outer diameter greater than 150, 200, 300, 450, or 600 mm, and/or an outer diameter between (about) 150 mm and (about) 1000 mm. Forming long pipeline segments (such as pipeline segments that are at least 200 meters in length in the field may lead to reduced pipeline cost and faster pipeline laying rates by reducing the number of end-to-end welding requirements. As further illustrative, non-exclusive examples, a multi-layered pipe according to the present disclosure may have a thickness greater than 10, 15, 25, or 30 mm, and/or a thickness between (about) 10 mm and (about) 40 mm. Additionally or alternatively, one or more of an inner metal tube, a second metal tube, a third metal tube (when present), and an Nth metal tube (when present) may have a thickness less than 5, 10, or 25 mm, a thickness of between (about) 3 mm and (about) 20 mm, and/or a thickness of between (about) 3 mm and (about) 7 mm. Due to the pipe being formed from metal stock, such as sheet metal stock, multi-layered pipes according to the present disclosure may be readily joined (i.e., constructed of suitable metallic materials) with conventional metal pipes using conventional fittings and welding processes.
Additionally or alternatively, a machine according to the present disclosure may be configured to form a multi-layered pipe having a length of at least 10, 30, 50, 10, 200, or 300 m, and/or a length of at least 100 times an outer diameter of the multi-layered pipe. Additionally or alternatively, a machine according to the present disclosure may be configured to form a multi-layered pipe that is configured to withstand an internal pressure of at least 3.45 MPa, 6.89 MPa, 20.7 MPa, 34.5 MPa, or even 68.9 MPa.
Other sizes, lengths, and pressure ratings are also within the scope of the resent disclosure, and the present disclosure is not limited to the enumerated values and ranges herein. Also, as the multi-layered pipes are formed from metal stocks, the metal stocks may be selected not only to permit welding of the bent stocks to form the individual tubes of the pipe using conventional welding techniques, but also to join separate lengths of pipe 200 together and/or to one or more lengths of conventional (single layer) metal pipes.
As discussed, installation sites for multi-layered pipes 200 according to the present disclosure may be in a variety of locations. Accordingly, machines 50 according to the present disclosure may be positioned in the same variety of locations or at least proximate to such installation sites. That is, a machine 50 may be positioned at least proximate to an installation site for a multi-layered pipe formed by the machine. Additionally or alternatively, a machine may be positioned within 0.1, 0.5, 1, 5, 10, 25, 50, or 100 km of an installation site for a multi-layered pipe according to the present disclosure. Additionally or alternatively, a machine may be positioned proximate to a drilling site for hydrocarbons and/or proximate to a wellbore associated with a hydrocarbon extraction site. Additionally or alternatively, a machine according to the present disclosure may be configured to position a multi-layered pipe formed by the machine into a wellbore associated with a hydrocarbon extraction site. Other locations are also within the scope of the present disclosure, including locations having distances relative to an installation site other than the enumerated values herein.

In the event that any of the references that are incorporated by reference herein define a term in a manner or are otherwise inconsistent with either the non-incorporated disclosure of the present application or with any of the other incorporated references, the non-incorporated disclosure of the present application shall control, and the term or terms as used therein only control with respect to the patent document in which the term or terms are defined.
As used herein, the term “and/or” placed between a first entity and a second entity means one of (1) the first entity, (2) the second entity, and (3) the first entity and the second entity. Multiple entities listed with “and/or” should be construed in the same manner, i.e., “one or more” of the entities so conjoined. Other entities may optionally be present other than the entities specifically identified by the “and/or” clause, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including entities, other than B); in another embodiment, to B only (optionally including entities other than A); in yet another embodiment, to both A and B (optionally including other entities). These entities may refer to elements, actions, structures, steps, operations, values, and the like.
As used herein, the phrase “at least one,” in reference to a list of one or more entities should be understood to mean at least one entity selected from any one or more of the entity in the list of entities, but not necessarily including at least one of each and every entity specifically listed within the list of entities and not excluding any combinations of entities in the list of entities. This definition also allows that entities may optionally be present other than the entities specifically identified within the list of entities to which the phrase “at least one” refers, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including entities other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including entities other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other entities). In other words, the phrases “at least one”, “one or more”, and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C”, “at least one of A, B, or C”, “one or more of A, B, and C”, “one or more of A, B, or C” and “A, B, and/or C” may mean A alone, B alone, C alone, A and B together, A and C together, B and C together, A, B and C together, and optionally any of the above in combination with at least one other entity.
It is believed that the disclosure set forth above encompasses multiple distinct inventions with independent utility. While each of these inventions has been disclosed in its preferred form, the specific embodiments thereof as disclosed and illustrated herein are not to be considered in a limiting sense as numerous variations are possible. The subject matter of the inventions includes all novel and non-obvious combinations and subcombinations of the various elements, features, functions, and/or properties disclosed herein. Similarly, where the claims recite “a” or “a first” element or the equivalent thereof, such claims should be understood to include incorporation of one or more such elements, neither requiring nor excluding two or more such elements.
It is believed that the following claims particularly point out certain combinations and subcombinations that are directed to one of the disclosed inventions and are novel and non-obvious. Inventions embodied in other combinations and subcombinations of features, functions, elements and/or properties may be claimed through amendment of the present claims or presentation of new claims in this or a related application. Such amended or new claims, whether they are directed to a different invention or directed to the same invention, whether different, broader, narrower, or equal in scope to the original claims, are also regarded as included within the subject matter of the inventions of the present disclosure.
This application claims the benefit of U. S. Provisional Application No. 61/297,568 filed Jan. 22, 2010.
