Title: Improvements in or relating to hydraulic control systems
IPC: F41G5/04
Filed: 1953-12-11
Abstract: 763,618. Ordnance, elevating and training gear. BAUER, R. E. Dec. 11, 1953 [Jan. 12, 1953], No. 34546/53. Class 92. [Also in Group XXIX] In a combat vehicle hydraulic power transmission system (see Group XXIX) the elevation of a cannon 91 is effected by a hydraulic motor 6 under the control of a reversing valve 41, and the traverse of the cannon is effected by a radial-cylinder motor 5 under the control of. a valve 40. Valves 40, 41 are controlled manually either from a gunner's or a commander's control mechanism. Valves 41, 40 carry rollers 258, 259 engaged in slots 252 in blades 226, 224 which are pivoted on the ends of a stub shaft 228 which is mounted in slots 225 of a housing. The stub shaft is normally urged by a spring 234 to the position shown in which rollers 260, 261 of the gunner's control mechanism are engaged in the slots 252. The gunner's control mechanism comprises handles 276 secured to a shaft 274, rotation of the handles about the axis of the shaft actuates, through a suitable linkage, the roller 261 to pivot the blade 224 and control the position of the valve 41. Rotation of the handles and the shaft 274 about an axis perpendicular to the shaft actuates the roller 260 thus pivoting the blade 226 and controlling the position of the valve 40. The commander's control is generally similar to the gunner's and when it is to be operative a switch 198 is closed, resulting in the actuation of a piston 188 which moves the stub shaft 228 to the other end of the slots 225, disengaging the rollers 260, 261 from the slots 252, and bring- ing rollers 264, 265 of the commander's control mechanism within slots 250 so that the valves 40, 41 are under the control of the commander's mechanism. Provision is made for traverse and elevation of the cannon manually.

The heat exchanger tubes 3, mounted within cavities 2 in the concrete pressure vessel 1, are heated by core coolant from the duct 5. Secondary fluid flows from duct 9 into the distributer 8 which provides a separate, parallel supply for each of the two banks. At low loads, the valve 9b is closed so that secondary fluid flows only through the tubes connected to the inner part 8a of the distributer, at a rate sufficient to ensure that overheating of the exchanger is prevented. Decay heat, produced during shut-down, may also be removed by the use of part of the exchanger after closure of 9b.

Abstract: 339,468. Armstrong, J. J. V., (Phoenix-Hermetic Co.). Nov. 23, 1929. Cupping.-Circular waste blanks 5 from a previous operation are placed in a scoop mouthed tube 10 from which they are fed to a punch 4 which punches them to size and cups them in a die 3 to form bottle caps. A blank 5 from the bottom of the pile in the tube 10 is engaged and sucked down past spring dogs 41 by a suction cup 17 on the end of a reciprocated plunger 16. Dogs 41 are threaded internally with gaps in between and are arranged in groups of 3 so that the bottom disc is supported at three points, and thereby causing the disc to bend when the suction cup first acts and so break any suction vacuum between the bottom disc and the one above it. The dogs 41 arc held in position by garter springs 47, 48 which allow a disc to be sucked down through them. Suction is applied to the cup when the port 38 of the channel 37 in the plunger registers with a port leading to a vacuum pump 33 synchronously cam operated. When the disc has been drawn down to position on the feed bed the vacuum in the cup 17 is broken by the port 39 registering with port 40 to atmosphere. The feed slide 58 (two side bars with cross connection 52) is now reciprocated in timed relation towards the die 3 by cam lever 54 so that spring-pressed fingers 62 push the previous discs on and under a spring- pressed plate 61 towards the die 63 and after the slide 58 moves back the discs are held on the bed by the spring-pressed plate 66 while the fingers 62 ride up over the discs and click behind them into grooves 61 ready for the next push forward. The disc which is located over the die 3 is held thereon by a spring-pressed dog 71, Fig. 3, which after punching retains the waste ring of metal until stripped therefrom by the end feed fingers. 62.
