Method and pulsating spray apparatus for inducing altered states in human beings

Abstract

A method for inducing a state of conciousness in a human being by bombarding the body with a fluid pulsating at a frequency corresponding with the frequency of brainwaves normal to the state being induced. A method is also disclosed for producing a concentrated fluid discharge by completely and rapidly blocking a flowing fluid stream under pressure, accumulating the resulting pressure rise and completely and rapidly releasing a concentrated fluid pulse. The invention includes apparatus for a producing a cyclic fluid discharge with a frequency from ½ to 120 pulses per second. Another method is disclosed for reducing fluid consumption without restricting fluid passageways by cyclically interrupting the flow of fluid and controlling the percentage of time during each cycle that fluid is allowed to flow.

Description

BACKGROUND—FIELD OF INVENTION

The present invention is a method for producing altered states in human beings wherein the appellation “altered states” denotes a change in consciousness from an existing state to another, within the context of the scientific discovery by Hans Berger in 1929, which documented the human brain giving off electrical energy in distinct, measurable patterns.

Decades of research have verified such patterns as corresponding to specific states of consciousness, measurable in cycles per second and categorized according to frequency as: Delta, Theta, Alpha and Beta.

Delta frequencies range from one to three cycles per second, Theta from four to seven, Alpha from eight to thirteen and Beta from fourteen to thirty and beyond.

All human beings and nearly all mammals share these patterns with minor variations among individuals.

Delta, is prominent in the deepest stages of sleep. Theta, is related to creativity, dream activity and relaxation. Alpha, is characterized by a relaxed but awake state of mind. Beta, is the brainstate of an awake and alert consciousness.

In 1975, in the context of stress research, J. Stoyva determined the occurrence of Theta activity in the brain as an indication of a state of consciousness incompatible with anxiety. Research further indicates that parts of the body other than the brain may be used to induce the manifestation of particular brainwaves.

To produce altered states in human beings, a method embodying the present invention comprises externally inducing the frequency common to the desired state on the physical body of a human being by means of precisely adjustable pulsating fluid sprays capable of a range of frequencies varying from ½ to 120 pulses per second.

BACKGROUND—DESCRIPTION OF PRIOR ART

In the art of pulsating fluid or water spray devices, such as disclosed in U.S. Pat. Nos. 3,762,648, 3,801,019, 4,010,899, 4,068,801, 4,141,502, 4,204,646, 4,330,089, 4,346,844, 4,579,284, 4,558,130, and 4,754,928, the predominant common feature is that the various means of producing fluid pulsation are water driven.

A drawback of these spray devices is that they consume part of the water's energy to operate. Another drawback is their lack of intent and ability to match the range of frequencies common to brainwaves. A further drawback, owing to these devices dependance on water flow and pressure to operate, is the unpredictable performance from one dwelling to another.

A water supply line 100 feet in length, or the equivalent combination of pipe lengths and fittings found in most households, will deliver, under a head of 115 feet of water, 9 gallons per minute at a velocity of 9 feet per second and 0 psig dynamic pressure.

Installing a spray apparatus compliant with water consumption regulations on this supply line would limit output flow to 2½ gallons per minute, reduce the fluid velocity to 2.6 feet per second and restore dynamic pressure within 10% to 15% of the initial head.

This 10% to 15% pressure loss results from fluid friction in the supply line. Known spray apparatus cannot recover this loss.

Some spray apparatus suffer the further drawback of causing an effect known as water hammer in the supply line when they operate. Water hammer can loosen and damage pipes and free sediments that clog fittings and fixtures attached to the line.

Other water driven spray apparatus incurr additional pressure losses aerating the fluid or diverting it through complex mechanisms essentially designed to present the supply pipeline with a constant fluid demand in order to avoid water hammer. The drawback of these mechanisms is that they are incapable of capturing the latent energy in the fluid stream.

Yet another further drawback of present spray apparatus is the reduction of fluid consumption by means that restrict flow. Internal restrictions consume fluid energy across small orifices or activating various mechanisms. Restrictions at the nozzle result in high discharge velocities out of small channels or orifices, giving the user the feeling of being stung by needles.

Some spray apparatus resort to increased size or number of orifices to reduce fluid velocity. This increases fluid consumption, mandating an internal flow restriction which in turn produces a bland discharge. Other spray apparatus aerate the discharge stream to compensate for its high velocity as well as to avoid watter hammer.

These solutions are not satisfactory to the user, as the resulting pulsating spray exhibits a much reduced force, or a noticeable lack of water flow and sometimes both.

In the Spray Nozzle disclosed in U.S. Pat. No. 3,762,648, the invention is specially directed to produce a pulsating or intermitently interrupted spray with no variations in back pressure in order to eliminate water hammer, and to produce an adjustable rate of pulsation that is independent from the pressure of the water supply.

A drawback to this method is that it is dependent on the fluid stream, dividing its energy between two flow paths, to maintain an even flow and thus eliminate water hammer. Another drawback is that being water powered, it uses part of the fluid's energy to operate its internal mechanisms. A further drawback is that it changes the pulse rate by proportionally dividing flow and pressure between the two flow paths, so that as the number of pulses increases, the force of the output spray decreases.

Another further drawback to this method is that presenting the supply line with no variations in back pressure constitutes what is essentialy a steady state, without possibility of realizing the kinetic energy latent in the fluid stream.

In the Skin Massaging Instrument disclosed in U.S. Pat. No. 3,861,383, the invention is directed to the treatment of a confined area of the skin, not exceeding 1½ square inches, with a water jet pulsating between 2,200 and 3,200 cycles per minute, with an impingement velocity on the skin between 9 to 18 feet per second. The apparatus contains an electric motor driving a piston pump and fluid reservoir, and confines its action by means of a rim pressed against the skin.

A drawback of such method is that the effective area is confined in order for effective action to take place. A further drawback is that its operating pulse frequency is many times that which is normal to brainwaves. Another drawback is that the fluid becomes contaminated from skin and hair particles in constant recirculation. Another further drawback is that it cannot operate from a standard supply pipeline.

In the Lavage Handpiece Apparatus disclosed in U.S. Pat. No. 4,278,078, the generation of fluid pulsations consists of an air powered pumping mechanism driving an eccentric crank, rod, and flat piston to cyclically squeeze a fluid filled flexible tube. The fluid overcomes the resistance of a downstream check valve and exits from a discharge nozzle as a fluid pulse. The apparatus uses a pinch valve to control inlet flow to the pumping area.

The drawback to this method is that an increase in the cycle rate produces an increase in the discharge velocity of the fluid and a corresponding increase in fluid consumption. A further drawback is that the cycling rate is limited by the recovery rate of the flexible tubing after it is deformed by the piston. Another drawback is that restricting the inlet flow also affects the recovery of the flexible tube. Another further drawback is the short life of the flexible tube at high cycling rates.

In the Method And Apparatus For Producing And Utilizing Percussive Liquid Jets, disclosed in U.S. Pat. No. 3,924,805, the generation of fluid pulsation consists of means of producing small cyclic variations of the discharge velocity of a continuous, uninterrupted liquid jet stream discharging from a single nozzle orifice, at elevated pressures and cycling rates, in the order of 1000 psig minimum, and at least 1000 cycles per second.

The drawback to this method is the effective range of its output, limited to approximately 4 inches, and the dangerous nature of the pressure it requires to function. Reducing the supply pressure to the level found in households and other residences renders its output completely inefective, while its cyclic frequency is many times beyond the sensory range of human beings.

In the Multiple Afferent Sensory Stimulation Device disclosed in U.S. Pat. No. 4,892,106, a a reproducing device emits sound and light signals for the purpose of audio and visual sensory stimulation for achieving mental and physical effects on a subject person.

A drawback of this device is that it confines its influence to sound and sight. Another drawback is its inability to remove physical stress from the body. A further drawback is the use of prerecorded source material, so that the program or pattern is set and cannot be changed. Another further drawback is that its use requires additional time and place set aside for it, something that individuals with a busy schedule may have trouble with.

Until the present invention, existing methods of producing discharge sprays have compromised contradictory requirements. To produce a strong pulsating spray the fluid stream must be fully and forcefully interrupted, yet the more accomplished the interruption, the more violent and destructive becomes the energy thus created in the supply lines.

The solutions demonstrated in the prior art focus on avoiding an ostensible problem without attempting to contain the source of the problem or harness its potentially destructive energy.

Water driven shower spray apparatus are designed to ameliorate pulsating shock and fluid consumption through partial flow interruptions, fluid diversions and aerating schemes. As a result, they share a characteristic feature; The energy of their discharge output is always less than the energy available at the inlet port.

The present invention reverses this conditions. Operating independently of the fluid supply, limiting fluid consumption without restricting fluid flow and accumulating the kinetic energy of the fluid stream, the apparatus releases a concentrated fluid pulse that exceeds the dynamic pressure available at the inlet port. Further, precise control of output pulse frequencies from ½ to 120 Hertz in half pulse increments allows the user to self induce brainwave frequencies corresponding to specific states of conciousness.

Pilot light 115 mounts on housing 99 and remains on when switch 114 is in the on position.

Operation— FIGS. 1 , 2 , 3 , 4 , 5 , 6 , 7

The manner of using the pulsating spray apparatus is similar to that used with pulsating spray devices in present use. The overall approach of the particular embodiment herein primarily illustrated is that of delivering two kinds of discharge sprays.

The first is a precisely controlled pulsating spray in which the kinetic energy of the pressurized fluid source is absorbed and retained during part of each cycle and subsequently discharged in a concentrated fluid pulse.

In operation, with selector switch 114 in the on position and a continuous fluid stream under pressure flowing thru supply pipe 116 , fluid enters the apparatus thru inlet port 37 , fills the volume contained within outer shell 31 and exits outlet port 32 , entering motor housing 49 thru inlet port 50 .

Port 50 leads to chamber 77 causing the fluid to split into two balanced streams and flow thru porting slots 72 a, 72 b in stationary sleeve 71 and porting slots 79 a, 79 b in rotating sleeve 78 . The fluid then exits thru discharge nozzle 89 .

As the fluid makes it way inside shell 31 , from inlet port 37 to outlet port 32 , it flows past retaining seal 42 and comes in contact with flexible membrane 46 a. Seal 42 acts against membrane housing 45 , preventing backflow. Membrane 46 a deflects due to fluid pressure and transmits part of its deflection to membrane 46 b by compressing the airspace retained between them and by actual contact. Similarly, depending on the pressure of the fluid source, membrane 46 b may also transmit part of its deflection to membrane 46 c which can, in turn, deflect into expansion chamber 118 contained between membrane 46 c and end cap 43 .

Slots 72 a and 72 b in sleeve 69 , mating slots 79 a and 79 b in sleeve 78 , all internal flow passages in the apparatus and threaded adaptor 116 are sized to exceed the capacity of conventional supply piping in order to minimize pressure losses due to flow restriction.

Fluid consumption is determined by a ratio of time between fully open and fully closed slots in sleeves 71 and 78 . The ratio is a function of the physical relationship between the width of the slots, their number and their perimeter distance.

The established physical relationship is independent of rotational speed.

When slots 72 a and 72 b in sleeve 71 are covered by the wall of sleeve 78 , the fluid flow towards nozzle 89 a is blocked and membranes 46 a, 46 b and 46 c deflect in direct proportion to the resulting increase in fluid pressure. Due to the kinetic energy of the fluid in the supply line, the energy stored by deflecting membranes 46 a, 46 b, 46 c, exceeds normal static line pressure.

When slots 72 a and 72 b in sleeve 71 line up with mating slots 79 a and 79 b in sleeve 78 , the blockage is relieved and the fluid moves towards discharge nozzle 89 a aided by the energy stored in membranes 46 a, 46 b and 46 c.

Sleeve 78 is driven by motor shaft 66 a thru flexible driver 81 at a rate precisely variable from fifteen to thirty six hundred revolutions per minute. The resulting fluid interruptions, occurring every half revolution, cause discharge pulse frequencies ranging from one half to one hundred and twenty pulses per second. Control knob 106 , attached to potentiometer 102 varies the rate of rotation of the motor. Dial plate 119 indicates the fluid discharge pulse rate in increments of one pulse per second across a 320 degree arc.

Membranes 46 a, 46 b and 46 c rapidly oscillate with system pressure as it varies in relation to fluid motion. Each time the flow is interrupted by the rotation of sleeve 78 , kinetic energy in the fluid is absorbed by further membrane deformation until fluid movement is zero and system pressure is at its highest.

Seal 42 maintains such peak energy by preventing return fluid flow and isolating shock waves from fluid supply piping. When slots 72 a and 72 b on sleeve 71 and mating slots 79 a and 79 b on sleeve 78 line up again due to the continuing rotation of sleeve 78 , a concentrated fluid pulse is released, immediately propagating towards nozzle 89 a.

Nozzle 89 a is retained by threaded insert 86 in spherical swivel joint 84 .

Preload springs 74 a, 74 b locate, orient and push stationary sleeve 71 against swivel joint 84 , creating enough friction to prevent swivel joint 84 from drifting while allowing full directional adjustment of the discharge pulse. Swivel joint 84 locates discharge nozzle 89 a in swivel joint access hole 88 . Flexible check disc 90 snaps in place in circular groove 91 inside nozzle 89 .

Disc 90 retains a column of fluid between sleeve 78 and discharge nozzle 89 , minimizing dead space, reducing noise and insuring the immediate transmission and release of stored energy from membranes 46 a, 46 b and 46 c thru nozzle 89 . Discharge nozzles 89 a, 89 b and 89 c are interchangeable, easily removable and replaceable without tools.

The second type of discharge spray is a continuous discharge in which fluid is delivered in an uninterrupted stream at a predetermined rate which meets U.S. State and Federal water consumption limits. When switch 114 in housing 99 is actuated in its momentary contact position, shaft 66 turns in a counterclockwise direction. One way clutch 69 , mounted on shaft 66 b and driven by shaft flat 67 rotates until it meets symmetrical stops 57 a and 57 b in rear cover 56 .

Shaft 66 a, at the opposite end of shaft 66 b simultaneously rotates sleeve 78 so that porting slots 79 a and 79 b partially overlap porting slots 72 a and 72 b in sleeve 71 , producing two opposed and equally controlled fluid openings and a continuous, restricted fluid discharge volume from nozzle 89 a. Sleeve 78 retains its position and the restricted fluid discharge continues when switch 114 is released from its momentary actuation. Switch 114 then reverts to its center off position, interrupting current flow to electronic circuit board 101 .

Actuation of the switch to its on position permits the motor to again rotate in a clockwise direction. The rotation rate of the motor in both clockwise and counterclockwise directions depends on the position of control knob 106 . Pilot light 115 remains on when switch 114 is in the on position.

Summary, Ramifications and Scope

Accordingly, the reader will see that the apparatus of the invention provides a convenient method of producing a change of consciousness in a human being that is supportive of daily activities. In addition, the apparatus provides an unmatched body massage, delivering the strongest possible spray out of a common water supply line. Furthermore, its operation under either pulsating or continuous discharge mode meets Federal and State water consumption guidelines.

While my above description contains many specificities, they should not be construed as limitations of the scope of the invention, but rather as an exemplification of one preferred embodiment thereof.

Many other variations are possible. For example, the energy absorption mechanism can be remotely placed in the supply line, or external to the main body of the spray apparatus; the motor can be of different type and its location external to the spray apparatus; the rotating sleeve can be made as a disc and the shape of the slots altered to produce the same effect, etc.

Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.

Claims

1. A method for producing a variably pulsed fluid discharge from a flowing fluid stream supplied under pressure by a pipeline, utilizing valve means and comprising the steps of:(a) repeatedly blocking and unblocking the flow of said flowing fluid stream, wherein one blocking plus one unblocking constitutes a cycle, wherein time elapses during said cycle, wherein the elapsed time during one blocking plus the elapsed time during one unblocking establishes a cyclic frequency, and wherein repeatedly blocking and unblocking the fluid stream produces a cyclic fluid discharge, (b) establishing the portion of cycle time elapsed during blocking in relation to the portion of cycle time elapsed during unblocking as a constant, wherein the fluid throughput of a cycle determines the fluid throughput of said valve means, and (c) varying the cycle time so that the proportion of cycle time elapsed blocking and unblocking the fluid stream during each cycle remains constant, wherein the cyclic fluid dicharge of said valve means is inversely proportional to its frequency, and preserves the established fluid throughput of said valve means, whereby said method produces a variably pulsed fluid discharge having a controlled fluid throughput independent of the frequency of the pulsed discharge.
