Claims
- 1. A method for intermittently interrupting the flow of a first fluid stream flowing within a groove-like open channel having generally opposing side wall members, said first stream at least partially conforming to and being laterally confined within said open channel by contact by said first stream with said side wall members, said side wall members thereby defining the lateral boundaries of said stream, said method comprising directing a transverse stream of a second fluid into the channel carrying said first fluid stream from a point within said channel wherein said second fluid initially is confined within said channel both by said side wall members and said first fluid in contact with said side wall members, said second stream being introduced with sufficient pressure to force said first fluid stream to break said contact by said first stream with said side wall members and cause said first fluid stream to move away from said second fluid stream and the confines of said channel.
- 2. The method of claim 1 wherein said first fluid stream substantially conforms to said open channel, is flowing within said channel at relatively high velocity, and wherein said transverse stream has sufficient pressure to disrupt the flow of said first fluid stream and cause said first fluid stream to dissipate.
- 3. The method of claim 1 wherein said first fluid stream is a liquid stream and said second fluid is a gas.
- 4. The method of claim 1 wherein said first fluid stream is given a desired cross-section prior to passage within said open channel by passage through an aperture which is aligned with said open channel.
- 5. The method of claim 1 wherein said first fluid stream is given a desired cross-section following passage within said open channel by passage through an aperture which is aligned with said open channel.
- 6. The method of claim 1 wherein said first fluid stream flowing within said open channel is directed at a textile substrate.
- 7. An apparatus for intermittently interrupting the flow of a first fluid stream flowing with a groove-like open channel having generally opposing side wall members, said flowing stream at least partially conforming to and being laterally confined within said open channel by contact by said first stream with said side wall members, said apparatus comprising:
- a. means for supplying said first fluid stream in alignment with said channel;
- b. means for directing a transverse stream of a second fluid into said first fluid stream from a point within said channel wherein said second fluid initially is confined within said channel both by said side wall members and said first stream in contact with said side wall members; and
- c. fluid supply means for supplying said second fluid to said directing means at a sufficient pressure to cause said first fluid stream to break said contact by said first stream with said side wall members and cause said first fluid stream to move away from said second fluid and the confines of said channel.
- 8. The apparatus of claim 7 wherein said channel is substantially "U"-shaped, and said directing means comprises an upwardly-directed passage in the base of said channel.
- 9. The apparatus of claim 7 wherein said means for supplying a first fluid stream in alignment with said channel includes a first fluid forming aperture which is aligned with said open channel and which has a substantially similar cross-section, said aperture being in fluid communication with a source of said first fluid stream.
- 10. The apparatus of claim 7 which further comprises a stream forming means for giving said first fluid stream a desired cross-section following the flow of said fluid stream within said open channel, said stream forming means including an aperture in substantial alignment with said channel.
- 11. The apparatus of claim 9 wherein said first fluid forming aperture and said open channel are comprised of a common slot which extends from said first fluid forming aperture to said open channel without substantial interruption.
- 12. The apparatus of claim 9 which further comprises a stream forming means for giving said first fluid stream a desired cross-section following the flow of said fluid stream within said open channel, said stream forming means including a second aperture in substantial alignment with said channel, and wherein said first fluid forming aperture, said open channel, and said stream forming means are comprised of a common, continuous slot which extends from said first fluid forming aperture to said open channel to said stream forming means without substantial interruption.
- 13. The apparatus of claim 7 which further comprises containment means for containing said first fluid stream after said stream is caused to leave the confines of said channel, said containment means comprising a cavity means located across the path of said first fluid stream in said channel, said cavity means being positioned in close proximity to, and directly opposite said open channel to permit said directing means to direct said first liquid stream into said cavity means from said open channel.
