Abstract: 1311188 Hydrostatic transmission control B C WILKINS 15 June 1971 [18 June 1970] 29600/70 Heading F2D [Also in Division F1] A hydrostatic transmission comprises a variable delivery pump 11 controlled to provide a constant delivery pressure 13 which is supplied to two or more motors 21, 24, 30, 44 which are respectively controlled to provide constant output torque, power or speed. The pump delivery pressure is supplied to a pressure responsive servo 15 which adjusts the pump displacement to provide a constant delivery pressure. Alternatively the pump delivery pressure may be supplied to a pressure responsive servo 16 which controls the speed of a driving engine 10 to provide a constant delivery pressure from the pump 11. The motor 21 is set to and maintained at a constant displacement to provide a constant torque at its output 23. The displacement of the motor 24 is varied by a pressure sensitive servo 27 in accordance with the pressure drop across an orifice 28 in the motor return line 29 to provide a constant power at its output 26. The displacement of the motor 30 and a variable throttle valve 34 are adjusted by a pressure sensitive servo 33 responsive to the pressure drop across the throttle valve 34 to provide a constant speed at the motor output 32. The linearly acting motor 44 is connected between two motors 39a, 39b which are connected hydraulically in series and have their rotors 40a, 40b connected together. The inlet to the motor 39a is connected to the high pressure line 13 whilst the outlet from the motor 39b is connected to the return line 45. If the displacement of the motors 39a, 39b are maintained in set positions a constant pressure is supplied to the motor 44. To maintain a constant flow to the motor 44, irrespective of pressure, the displacement of the motor 39b is set to a value giving maximum permitted pressure to the motor 44 (when the displacement of the motor 39a is maximum) and controlling the displacement of the motor 39a in accordance with the flow required to the hydrostatic motor 44. To maintain a constant power at the motor 44 the displacement of the motor 39b is set to a position giving maximum pressure (when the displacement of the motor 39a is maximum) and controlling the displacement of the motor 39a to maintain a constant flow into the inlet port 42a of the motor 39a. An accumulator 48 may be provided in the high pressure line 13.

Abstract: 1315653 Heat-recoverable alloys; couplings; electrical contacts; formers FULMER RESEARCH INSTITUTE Ltd 29 April 1970 [1 May 1969] 51178/72 Divided out of 1315652 Headings B3A and B3V [Also in Divisions C7 and G1] A method of making a heat-recoverable article comprises cooling a binary alloy of uranium containing 2 to 7 wt. per cent molybdenum, 3 to 11 wt. per cent niobium, or 2 to 7 wt. per cent rhenium, or a manganese-copper binary alloy containing 5 to 50 wt. per cent copper in a first shape from a first temperature to a lower temperature, and deforming the alloy at the lower temperature into a second shape, said temperatures being such that if the alloy were reheated to an appropriate temperature it would at least partly regain its first shape. Articles made from such heat recoverable articles are useful in apparatus when a change of shape is necessary, e.g. as tubes in couplings, which tubes change shape to grip the two elements to be connected together, as temperature-responsive elements in switching devices, and as formers or dies on which plastics or metal sheet can be shaped whereafter the former or die is caused to shrink away allowing the removal of the shaped sheet, and the former or die is then caused to revert to its original shape for the next operation.

Abstract: 1316644 Semi-conductor devices MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 15 May 1970 23680/70 Heading H1K A diode is produced by placing a dopant pellet on a semi-conductor body, heating to adhere the pellet to the body, inverting the body and then heating to alloy the pellet to the body to form a PN junction. A hyper-abrupt junction diode is produced by placing a pellet comprising 1 part Al, 55 parts Sb and 800 parts Sn on the upper face of a P-type Si wafer and heating until the pellet melts, goes spherical and adheres to the wafer. The wafer is then allowed to cool, inverted so that the pellet hangs below the wafer, and heated to alloy the pellet to the wafer. A lead wire is soldered to the pellet and a Mo electrode is attached to the opposite face using an Al-Si eutectic solder. The wafer may be of Si or Ge and the pellet may be of P, As, Sb Bi, B, Al or In and a carrier of Sn, Pb, Au or Ag may be included. The shape of the alloyed region depends on the crystallographic plane of the surface, being triangular for (111) planes and square for (100) planes.

Filed: 1971-12-23
Abstract: 1323520 Apparatus for preventing oil pollution TEXACO DEVELOPMENT CORP 23 Dec 1971 60197/71 Heading BID [Also in Division E1] Apparatus for gravity separating of oil and water and preventing pollution of a large body of water by an oil-containing discharge comprises a caisson 21 which is arranged upright in the body of water so that the bottom 28 is sunk into the bed of the body of water and its top extends above the water surface (Fig. 1 not shown). A body of water is thus enclosed within the caisson and can only communicate with the main body of water through openings 32-35 which are adjacent the bottom. Oil-polluted water is fed into the caisson through inlet pipe 38 with horizontal inlet holes 39. The oil floats on the surface of the water and hence remains trapped within the caisson whilst the water can circulate through the lower openings. Oil is removed periodically as necessary to prevent its accumulation allowing escape through the lower holes. The top of the caisson is arranged to be sufficiently above the water surface to prevent waves washing over the top into the caisson.

Abstract: 1331774 Motor vehicle lamps JOSEPH LUCAS (Industries) Ltd 19 May 1971 [20 June 1970] 30046/70 Heading F4R A vehicle lamp assembly comprises a reflector unit 11, a bulb holder (14 or 15, Fig. 2, not shown) detachably engaged with the reflector unit by, for example, a snap fit, and a lens unit 18 having a screw fastening means 24 secured thereto, the fastening means having a portion which extends through an aperture in the reflector unit and can be used both to secure the lens unit to the reflector unit and to secure the assembly in position on the vehicle body 28. The fastening means is secured to a spigot 23 on the lens unit by driving it into the spigot by ultrasonic techniques. The dimensions of the components are such that when the two units are brought together to compress a sealing gasket 22 therebetween the end of the spigot 23 is spaced by a small distance from the reflector unit 11. A washer or other fastening means is then placed on the screw means 24 to hold the units in position and the lamp assembly is applied to the vehicle body 28 with the interposition of a further sealing gasket 26, the screw means extending through an appropriate aperture in the body. A nut 27 is then tightened on the screw means to compress the gasket 26 and absorb the remaining play between the units. Ribs 25 on the reflector unit around the screw means 24 minimize the risk of damage to the lamp assembly due to over-tightening of the nut 27.
