Filed: 1921-04-18
Abstract: 161,957. Compagnie des Forges et AciÚries de la Marine et d'HomÚ- court. April 19, 1920, [Convention date]. Artillery and like high-pressure gauges. - Measurement is by the crushing of small cylinders of copper or like material between the head of a piston movable in a steel block and a plug screwed into the block, the pressure-fluid acting on the piston and a rod passing through the plug acting upon indicating means. The steel block 1 is bored out to receive the piston 5 and two screwed plugs 7, 8, the piston head 10 sliding within the plug 8, while an extension 18 of the piston slides within the plug 7. The cylinders of copper 11 mounted in holes in a paste-board washer 12 are placed between the piston head 10 and the plug 7. A tight packing-ring 14 surrounds the piston 5, ducts 17 allowing any leakage to escape, while airducts for use while filling and closed by a needle valve 21 are provided. Pressure fluid is admitted at 2 and passes to the piston through the duct 3 moving the piston and piston-head to compress the cylinders 11. The end of the extension 18 moves a pointer 19 over a scale of pressures 20, the reading being verified afterwards by actual measurement of the cylinders 11 which are kept as a permanent record of the test.

A reversible gear pump or motor has gears 11, 12 flanked by end bushes 10, 17 surrounding bearings 8, 15. Valve means are provided so that high pressure fluid, from the inlet or outlet according as the machine operates as a motor or pump, is directed to a chamber 18, to urge the bushes against the gears, and low pressure fluid, from the outlet or inlet, is directed to chambers 19, 20 to urge the bushes, through the bearings 8, 15 and pistons 21, 22, against the gears. The chamber 18 communicates with the inlet and outlet through flap valves (Fig. 3, not shown), so that only high pressure fluid is admitted. The chambers 19, 20 communicate with the inlet and outlet through passages 43 and bore 42, the latter containing a piston valve 35. The bore 42 is connected to the inlet and outlet by passages 30, 31 (Fig. 4), fluid from the passages 30, 31 passing to chambers 38, 39 respectively, so that the piston 35 is urged to the low pressure end, and low pressure fluid (from passage 31 in Fig. 4) passes to the passages 43. Preferably the area subjected to high pressure is greater than the area subjected to low pressure. In a modification (Figs. 6 and 7) the passages 30, 31 lead into an arch-shaped groove 48, the passage 30 being widened, at 44 to accommodate a valve 57 bored so that low pressure fluid (as shown, from passage 31, through groove 48) communicates with the chamber 19, and the high pressure fluid (passage 30) is cut off.

Filed: 1927-05-02
Abstract: 298,097. Cooper, C., Henshaw, D. M., and Holmes & Co., Ltd., W. C. May 2, 1927. Drying gases.-Fuel gas, such as town's gas, is dried, preferably by contact with hygroscopic material in the liquid state, while under a pressure, for example up to 50 pounds per sq. in. or more, higher than that necessary for securing its delivery at suitable pressure at distant points of the distributing system. The gas may also be cooled sufficiently to dissipate compression heat or to a further degree, in the manner described for example in Specification 285,936. The drying agent may be concentrated for re-use periodically or continuously, as described in Specification 246,841. The gas after treatment with a liquid agent may be brought into contact with solid drying agents, such as calcium carbide, which yield gaseous products when reacting with water. The gas may be passed upwards under pressure through vessels down which the hygroscopic liquid flows through pertorated trays. The pressure may be diminished during the drying operation or intentionally before distribution of the gas.
