[Also in Division G6] Apparatus for transferring a load, e.g. spent fuel elements between two reservoirs 1, 2 interconnected by a tube 3 comprises a carriage 6 having rollers (Figs. 2, 3, not shown) running on the tube wall and circular end plates 8, 9 functioning as pistons. The tube 3 is always filled with the reservoir fluid and may be closed at its ends by valves 4, 5. Extensions 3<SP>1</SP>, 4<SP>1</SP> and 311, 5<SP>1</SP> at the ends of the tube serve as guideways to permit the carriage to be moved into its loading and unloading positions, one such position being shown in chainlines. The fluid pressure system for moving the carriage 6 comprises pipes 15 . . . 18 opening into the tube 3 and reservoirs 1, 2, two 4-way cocks 13, 14 and a pump 12. In operation, to move the carriage from the chain-line position shown to a similar position in the reservoir 2 the valve 4 is opened and the cocks 13, 14 are positioned so that the pump may drive fluid along a path a through pipes 16, 17, the pressure differences acting on the two faces of the plate 9 causing the carriage to move into the tube. When the plate 8 enters the tube these pressure differences act on the plates 8, 9. The plate 9 arrives at the opening to pipe 11, the pump is stopped, valve 4 is closed and valve 5 opened. The cocks 13, 14 are positioned so that the pump 12 may drive fluid along a path b through pipes 18, 15 whereby the pressure differences acting on the plates 8, 9 and eventually on the two faces of the plate 8 move the carriage into the tube extension 311, 5<SP>1</SP>.

Abstract: 1276234 Stamping KAISER ALUMINUM & CHEMICAL CORP. 14 Sept 1970 [22 Sept 1969] 43833/70 Heading B3Q Seamless can-forming apparatus comprises a closed fluid circuit, an actuating piston 36 mounted in one portion of the circuit, at least one separate forming punch 44 mounted on opposite sides of the piston and drive means 14 for activating the fluid in the circuit so as to urge the punches 44 alternately to make single uninterrupted working strokes. Means are also provided for replenishing fluid lost on one side of the piston 36, including a pump device 74 connectible to the fluid deficient portion of the circuit, valve means 76 for connecting the pump device 74 to the fluid circuit so as to actuate the device to supply the fluid deficient portion and sensor means 103 activated by an overstroked punch to operate the valve means 76. The piston 36 is reciprocated through the action of a yoke 26 and if fluid leaks from one side of the circuit, e.g. the right-hand side, then the piston will overstroke on that side. The left-hand punch 44 will pass a line 105 and enter the magnetic field of the sensor 103. The sensor generates and transmits a signal to its amplifier 97, which in turn sends a signal through one of its output leads, e.g. 100, to energize a solenoid 78 and move the spool of a valve 76 to interconnect valve ports B with C and A with D. Fluid from a chamber 32 and activated by the yoke 26 passes through lines 60a, 82, valve ports B, C and line 81 to move a piston 94 of the pump 74 rightwardly. Fluid is expelled from the pump through a line 83, ports D, A, check valve 84 and lines 80, 58a into the fluid deficient right-hand portion of the circuit. When this portion of the circuit requires more fluid, the left-hand amplifier will energize its lefthand solenoid 78 to interconnect valve ports A with C and B with D so that the piston 94 travels leftwardly. Make-up fluid is supplied from a reservoir 54 by a pump 50 and the main fluid circuit is initially filled through bleed valves 106. Conduits 110 may be used to bleed fluid to the reservoir 54. Fluidic type sensors may be used instead of the electro-magnetic sensors 103.
