Abstract: 437,354. Revolving-cylinder pumps. ROSAK, K., 6, Wullenweberstrasse, Berlin. Jan. 25, 1934, No. 2640. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 26, 1934]. [Class 102 (i)] [See also Group XXIX] In a hydraulic or pneumatic pump, compressor, or motor, each piston controls the inlet to the preceding piston and the outlet from the following piston or vice versa. In the hydraulic gear shown in Fig. 1, the driving shaft 3 carries a cylinder rotor 4, having sets K<1>, K<2>, K<3> of pump cylinders with pistons co - operating with eccentrics 32<a>, and sets M<1>, M<2>, M<3> of motor cylinders with pistons co-operating with eccentric surfaces 14, 15, 16 on a member 17 carried by the driven shaft 20. The eccentrics 32<a> are compound, the inner portions 29, 30, 31 being carried by a sleeve 23, and the outer portions being connected to each other and to a member 25<a> on a sleeve 22 by projections engaging recesses. The eccentricity is varied by turning the sleeves 22, 23 in opposite directions by gears 27, 28. Each piston has two recessed parts s, d, Fig. 2, and controls passages between the cylinders and from the cylinders to low and high pressure channels 11, 12. Any pump piston such as 7 controls passages sa, sk putting the channel 11 into communication with the operative end of the cylinder of piston 8, and also the passages da, dk between the channel 12 and the cylinder of piston 10. The motor pistons are similar, and a pump plunger 21 actuated by an eccentric 33 supplies make up liquid from a supply tank to the channel 11. In modifications, the pump pistons may be operated through connecting-rods, the motor pistons may operate inwardly in conjunction with eccentrics on the driven shaft, or the pump and motor may be of the swash-plate kind.

Abstract: 1,147,015. Semi-conductor devices. ITT INDUSTRIES Inc. 18 Jan., 1968 [26 Jan., 1967], No. 2691/68. Heading H1K. A Zener diode is produced by alloying doping material to a wafer through a surface zone produced by the planar process. The alloying step is performed in a temperature gradient in which the temperature increases towards the inside of the wafer. As shown, a P-type region 6 is produced in a wafer of N-type silicon 1 by the planar process using an oxide mask 4. A layer of aluminium is evaporated on to the surface, photomasked, and etched to leave an area 2. The wafer is then mounted on a graphite heating plate in a water cooled quartz reactor containing an inert gas and the aluminium is alloyed through region 6 to produce P + type region 5. The electrode is strengthened by evaporating on a layer of aluminium followed by a layer of silver using the same mask and without breaking the vacuum. The silver layer is tempered and the electrode is thickened by electroless plating. A plurality of such diodes are simultaneously produced in a single wafer which is then subdivided, the individual divider being mounted in a sleeve or envelope with a pressure contact applied to the strengthened electrode. Reference has been directed by the Comptroller to Specifications 1,023,579 and 1,052,673.

Abstract: 643,460. Fluid pressure Jacks. ELECTROL, Inc. Jan. 30, 1947, No. 2935. Convention date, Feb. 14, 1946. [Class 78 (iii)] [Also in Group XXIX] A hydraulic jack has a piston 20 working in a cylinder 10 and means for locking the piston to the cylinder at the end of its stroke, and, manually or hydraulically operable mechanism is provided to release the locking means and at the same time open an exhaust valve to permit free movement of the piston in the cylinder; the manually operable mechanism comprises a shaft, rotatably mounted transversely in the end of the cylinder, having cams which effect unlocking and open the exhaust valve when the shaft is rotated. The piston 20 is provided with a flange 23 having apertures 24 for receiving balls 25 which are retained in the recesses 24 by an underlying disc-like projection 26 on the piston. The balls 25 co-operate with a channel member 29 and are arranged so that they can pass by the flanges of the member, but are forced intc these channels by a locking piston 31 slidably mounted in a cap 11. The piston 31 has a projecting end 33 which cannot completely enter the flange 23 until the balls 25 are opposite the channel 29. The piston 31 is forced to the right by springs 34 causing the balls 25 tc enter the channel 29, thus locking the piston An inlet port 35 overlying a channel 36 in the periphery of the piston 31 communicates by small passages 37 with the space in which the balls 25 are received and by introducing pressure through the port 35 the piston may be unlocked. The niston 20 mav be released manually by rotating the cam elements 40, 41 which are provided with flats 47, 48 which engage a wall 49 bounding an opening 46. The cam 41 has an enlarged opening 52 to permit about a 45 degrees rotation.
