Abstract: 1,047,011. Locking levers; toggle mechanisms. DE HAVILLAND AIRCRAFT CO. Ltd. Oct. 22, 1962 [Oct. 20, 1961], No. 37727/61. Headings F2E and F2K. [Also in Division B7] A manual control member, e.g. for setting an aircraft flap, is movable in a single plane between limit positions, and has one or more selected intermediate positions at which it is arrested by one-wayacting arrestor means, the member being releasable from an intermediate position by a to-and-fro movement of the member in a different plane when it is at that position. Fig. 2 is a view on Section A-A of Fig. 1, the control member being a lever pivoting about pin 11 for control movements, and composed of two parts 3, 4, pivoted together on pins 5, 6. Pivoting of part 3 on part 4 is normally prevented by a slot 12 in the housing 1, in which part 3 moves. A pawl 19 is pivoted on part 4 by pin 20, and has an arm forming a toggle linkage with a spring box 21 pivoted to part 4 at 22, so that either a tip 23 of the pawl contacts a ratchet segment 16, or a roller 24 journalled on an arm 19 contacts the ratchet, as shown. Part 4 contains a slider 7, which may be biased by a compression spring 8, having a roller 9 engaging a cam slot in part 3. The pin 25 of roller 24 projects so that it may be contacted by slider 7. When the lever is moved from right to left as seen in Fig. 1, with the pawl in the inoperative position shown, the roller 25 rides up on a tooth 18 on the ratchet, and trips the pawl to the operative position, in which tip 23 contacts the ratchet. The lever is then arrested when the tip 23 abuts the next tooth 18. To release the lever for further movement, recesses 14 are formed in the housing 1, so that a thickened part 13 of the lever is in register with a recess whenever the pawl tip 23 abuts a tooth 18. The operator then pivots the part 3 of the lever on pins 5, 6, so that the projection 13 enters recess 14, and cam slot 15 and roller 9 cause slider 7 to rise and strike pin 25, resetting the pawl to the inoperative position shown in Fig. 1. Part 3 of the lever is then returned to its normal position, and the lever can be advanced. On moving the lever from left to right, both roller 24 and tip 23 ride over the teeth 18, which are appropriately shaped so that such movement is not interrupted. A further pawl and ratchet are added if such movement is to be interrupted.

Abstract: 1,024,573. Producing pure water from raw water. DESALINATION PLANTS (DEVELOPERS OF ZARCHIN PROCESS) Ltd. Jan. 1, 1962 [April 14, 1961], No. 39156/61. Heading B1B. [Also in Division F4] Pure water is produced from sea water or other raw water by introducing it into a chamber 20 which is maintained at low pressure, e.g. 3 mm. Hg., so that part of the raw water flashes into vapour and the remainder is cooled with the formation of ice crystals, the mixture of ice and brine is pumped from the base of chamber 20 into separator 26 where the ice is freed from the brine, the ice is then mixed with pure water in trough 36, the mixture is pumped through pipe 46 to annular trays 48 mounted in chamber 50 surrounding chamber 20, and the vapour flashed off in chamber 20 is caused by radial compressor 54 to flow downwards into contact with the mixture of ice and pure water in the trays so that the vapour condenses and the ice melts thus increasing the volume of pure water. Raw water is introduced into the system through pipe 10: it flows first through deaerator 12 and then through heat-exchanger 16 where it is cooled to about 30 ‹F. by heat exchange with cold concentrated brine and cold pure water. The cooled raw water is passed through pipes 18 and 150 into a manifold 148 which distributes the water to conduits 152, whence it flows out through elongated openings 158, at the tops of the conduits, and end-ports 160. and then flows down plates 156 and the inside cylindrical wall 94 in film-form. In separator 26, the brine is forced out through screens 28, and a cylinder of packed ice crystals moves upwards to scraper 34 which removes the top of the ice cylinder and deliversit into trough 36. Spray-heads 38 are provided at the top of separator 26 for spraying pure water on to the top of the porous cylinder of ice ; this water runs down in the interstices of the ice and removes adhering brine. The mixture of ice and pure water from trough 36 is distributed all around each tray 58 by a plastic pipe 126 having notched-openings 130. Pure water leaves the trays via bores 122, and collects in the bottom of chamber 50. This pure water is withdrawn through pipe 60, and is in part pumped for use at the top of separator 26 while the remainder flows through heat-exchanger 16 to tank 82. Some of the brine withdrawn from the base of separator 26 is mixed via pipe 92 with the incoming raw water, and some of it is recirculated to the base of chamber 20 via pipe 86. tube 88 and spray-head 90. The remainder of the brine is discharged via heat-exchanger 16 and pipe 68. Cooling-coils 64, connected to refrigeration unit 66. are provided in the lower end of chamber 50. A vacuum pump (not shown) is connected to chamber 50 in the zone of the coils 64. The concentration of fruit juices is briefly referred to, and the claims cover the separation of solvent from any solution by evaporation and freezing.
