Abstract: 1,234,010. Hydraulic single-stroke apparatus. JOHANNES ERHARD, H. WALDENMAIER ERBEN SUDDEUTSCHE ARMATURENFABRIK. Sept.30, 1969 [Oct. 1, 1968], No. 47917/ 69. Heading F1P. [Also in Division F2] A piston 8 slidable in a cylinder 7 to rotate a valve 16 is moved in one direction by liquid supplied by a pump 1 and in the opposite direction by liquid supplied from a pressurized reservoir 23. A by-pass line 17 containing non-return valves 18, 19 inter-connects the cylinder chambers on opposite sides of the piston, the non-return valve 19 being opened by the piston 8 at the end of its stroke thereby to allow liquid from the pump 1 to replenish the reservoir 23. Movement of the piston is controlled by a valve 5 which either isolates, pressurises, or exhausts a line 6 connected to the larger cylinder chamber. The piston acts through a rod 10 and links 12, 13 to operate the valve which is provided with a position indicator. The by-pass line may be in the piston, Fig. 2 (not shown). A modified configuration is described, Fig. 3 (not shown).

Abstract: 1,264,368. Clamping arrangements. G. B. BOUCHERIE. 11 June, 1969 [27 June, 1968], No. 29664/69. Headings B3B and B3C. [Also in Division A4] In a transfer machine a trolley 23 carries workpieces 34, 35 which are to be clamped in position by cylinders 32, 33. To initially operate the cylinders and then maintain the operative pressure each trolley has a distributer 18, an air tank 43, a control valve 39 and a hand controlled valve 37 which is normally open. In operation, when a trolley reaches a particular station, where it is fixed by known means, a valve 74 is operated by a movable cam 77 such that compressed air passes into space 71 to free piston 56 toward the distributer 18 so that piston rod 57 mates in a cylindrical part 46 of the distributer 18. An adjustable stop 63 mounted on connector 19 operates a valve 61 so that compressed air passes through the connector, into the distributer and thence to the cylinders 32, 33 via the air tank 43 and control valve 39. To return piston 56 cam 77 is moved so that valve 74 passes compressed air to space 68. A spring-biased valve 52 stops loss of pressure from the air tank. When all the necessary operations are completed at various stations, the cylinders are released by a pressure cylinder 22 which actuates rod 40 of valve 39 which connects pipe 38 to exhaust opening 41 whilst temporarily interrupting the connection between pipes 38 and 42 so as to maintain tank 43 under pressure. The workpieces 34, 35 could be clamped by one cylinder only.
