Patent EP-0445908-A1 (EP)
Inventor: LOVE FRANKLIN SALDLER
IPC: D04H1/46
Filed: 1991-01-17
Abstract: A method and apparatus for forming and selectively interrupting one or more fluid stream which is confined within an open channel. A transverse fluid stream is introduced into the channel at a point under the stream flowing within the channel. Introduction of the transverse stream at relatively low pressures is sufficient to cause the stream within the channel to leave the confines of the channel. If the channel is directed at a target, the method and apparatus will allow intermittent and selective interruption of a fluid stream flowing within the channel and directed at the target. The source of the transverse fluid stream has an arcuate or curved outlet portion to prevent fluid from the open channel from accumulating therein.

Abstract: Tensioning and lashing device for the stepwise tensioning and stepless release of lashing lines, consisting of a bracket (1), of a pivoting arm (2) and of a ratchet mechanism which is composed of ratchet wheels (3, 3') and blocking slides (5, 5'). Because a plurality of blocking slides (5, 5') is used, a higher lashing force can be absorbed or a stepwise tensioning of the lashing line in blocking-step sizes different from the tooth division t is possible. To release the lashing line, there is formed on the pivoting arm (2) a control cam (40) which brings the blocking slides (5, 5') into a disengaged position and consequently the ratchet mechanism into a release position. The use of curved blocking slides (5, 5'), of a curved driving slide (20) and of a leg spring (41) as a single spring element for the blocking slides (5, 5') allows a reduction in the constructional height of the device and has the effect of saving components and space. <IMAGE>
