Abstract: 939,529. Diaphragm pumps. KIGASS Ltd. Nov. 2, 1959 [Oct. 31, 1958; May 2, 1959], Nos. 34919/58 and 15065/59. Class 102(1). A bellows pump comprises a bellows 2, Fig. 1, preferably of nylon, having a closed end 2a and an open end 2b which is clamped to the end of a housing 1 by a liner 4. The closed end of the bellows is urged against a plunger 14 either by its only resilience or by a spring 12 and the end 9 of the housing contains inlet and outlet valves 31, 19 respectively. A non-leak valve may be provided in the form of a plug 23 having a stem extending through a port 22 which stem is contacted by the bellows during the delivery stroke. The spring 24 of the leak valve is stronger than that of the outlet valve 19. In the embodiment shown in Fig. 3 the plunger is arranged to be locked at its inner position. The plunger 14c is hollow and houses a piston 39 having a slot 42 and a groove 37a which fixes in grooves of a boss formed on the end of the bellows so that the plunger may rotate relatively to the bellows. A collar 44 is fixed to the end of the plunger 14c by a pin 41 passing through the slot 42, and the collar carries two rollers 46 which engage in slots 48 of the liner 4b. When the plunger is to be locked the plunger is actuated and the end of the bellows engages the spigot 11 and seals the port 22, after which the plunger is further depressed and moves relatively to the piston 39, the plunger can then be rotated and the rollers moved into circumferential slots leading from the slot 38. In a modification, the collar 44 and piston 39 are omitted and the plunger is formed with a threaded portion which screws into the end of the housing to lock the plunger at the end of its outward stroke as in Fig. 2 (not shown), in this embodiment the non-leak valve is retained.

To close the table, the end rail is pulled out slightly and the leaf 10 is pushed down below the level of the top 8. The end rail is then pushed back until the parts 8. 9 meet. The long sides 1, 2 of the table frame are provided with double side rails 3, 3<x> which are secured to the sides 2. Runner blocks 6, mounted between the rails 3, 3<x>, are fixed to the sides 1, while ledger rails 13 extending the full length of the table top 8 are fixed to its underside. This arrangement permits extension without prejudicing the bearing strength of the table. Two buffer blocks 15 carrying compression springs 16 are fixed in the channel formed by the runners 7 assist in closing up the joint between the parts 8, 9 when the table is extended. The table may be retained in closed or extended position by means of a sliding bolt.

Abstract: 1341810 Helicopter control system UNITED AIRCRAFT CORP 1 Aug 1972 [16 Sept 1971] 35803/72 Headings B7G and B7W A helicopter control system includes a speed control 22 providing an input to a fuel control 34 and means for biasing the said input in accordance with an input from a collective pitch control stick when the speed control is within a certain range of positions. The speed control 22 is connected to the fuel control 34 by the wire 32 of a Bowden cable 24, and a lever 44 positioned by the collective pitch control stick bears against an abutment 42 at one end of the cable sheath 36, the other end being fixed at a bracket 38. When collective pitch, and thus the load on the engine, is increased, lever 44 is moved anticlockwise, and spring 40 causes fuel control 34 to move clockwise to increase fuel supply. However when the speed control 22 is in stop or idle positions, cam 50 will so position lever 36 that cable 60 connected to the abutment 42 is taut, so that movement of the lever 44 does not affect the fuel control 34; likewise when the speed control is set to a maximum the spring 40 will be compressed, and again movement of the lever 44 will not affect the fuel supply. Instead of the spring 40 there may be a spring (62), Fig. 3 (not shown), between the lever 44 and a further abutment (64) on the Bowden cable sheath.
