IPC: F16H47/08
Filed: 1958-03-04
Abstract: 844,200. Hydro-mechanical variable-speed gear. EATON MANUFACTURING CO. March 4, 1958 [March 13, 1957], No. 6895/58. Class 80 (2). In a combined torque-converter and planet gear wherein first and second turbines 34, 35 drive respectively different-sized ring-gears 60, 61 meshing stepped planets on a carrier 69 fast on an output shaft 13, a third turbine 36 is fast to a sun 62 meshing the small planet step and prevented from reverse rotation by a one-way detent 75 on a fixed sleeve 43.

Abstract: 1,093,802. Endless-track tensioning devices. GO-TRACT Ltd. Nov. 26, 1965 [Feb. 17, 1965], No. 6940/65. Heading B7H. An endless - track vehicle has each track entrained over an idler wheel 16 displaceable to tension the track by an hydraulic ram 34 connected to an hydraulic circuit including a source of hydraulic pressure fluid, at least one relief valve for preventing the pressure applied to the ram from exceeding a predetermined value, and a control valve for altering the pressure applied to the ram, the control valve being actuated by means controlling the direction in which the vehicle is driven so that the track tension is altered whenever there is a change in direction. As shown, an engine-driven pump 40 supplies fluid to the rams 34 through a control valve 70 which is linked by a mechanical, hydraulic or electric actuator to the gear-shift or gear-box 53 so that selection of forward or reverse gear automatically moves the valve to a corresponding position. In forward gear the ram pressure is limited by a low-pressure relief valve 52 to provide a low track tension, and in reverse a higher track tension is provided by high-pressure relief valves 64 which limit the pressure of fluid trapped between the cams 34 and the valve 70. In Fig. 5 (not shown) separate control valves are provided for each ram and each valve includes a third position wherein the ram pressure is limited by a medium pressure relief valve when neutral is selected. In Figs. 7, 8 (not shown), means forming the subject of Specification 1,093,803 are also provided whereby the control valves are separately controlled from the steering mechanism of the vehicle to increase the tension of the inner track during a turn.

Title: Improvements in and relating to diaphragms for pressure actuated apparatus
IPC: F16J3/02
Filed: 1940-04-17
Abstract: 545,626. Flexible diaphragms. SPERRY GYROSCOPE CO., Inc. April 17, 1940, No. 6977. Convention date, April 22, 1939. [Class 135] [Also in Group VIII] A diaphragm for fluid-pressure apparatus is formed of fabric impregnated and faced with rubber &c. and bonded to a central disc or discs 6, 7 of metal &c. and if desired to a peripheral ring or rings 4, 5. During manufacture the central fabric portion may be put under tension, so that the finished diaphragm has no central position determined by its own stiffness, e.g. by offsetting the central area during bonding. Two such diaphragms may actuate a fluid relay by connection to its valve stem 10. The diaphragms may be actuated by air pick-offs, e.g. on directional and rate of turn gyroscopes controlling flow into pipes 27, 28 leading to a mixing pipe 23. The diaphragm may alternatively actuate a swivelling jet pipe discharging differentially into relay inlet pipes. Specification 515,290 is referred to.

Title: Improvements in and relating to heating installations for motor vehicles
IPC: B60H1/03
Filed: 1962-02-22
Abstract: 926,474. Ventilating vehicles. WEBASTOWERK G.m.b.H. Feb. 22, 1962 [March 8, 1961], No. 6993/62. Class 137. [Also in Group XIII] A heating and ventilating installation for vehicles driven by liquid-cooled engines comprises a cock 8, heating device 10, and a heat-exchanger 12 connected in series with each other and in parallel with the vehicle radiator 2. As shown, when the engine 1 is cold, the cock is moved to position I which puts the engine jacket in series with the cock, heating device 10, heat-exchanger 12 via pipes 7, 9, 13, 18 and 19. At the same time the heating device circuit is made by switch 17, thus medium flowing round the circuit is heated at 10 and warms engine 1, a very small amount of heat being lost to the vehicle's interior via heatexchanger 12. When the cock is in position II pipes 9 and 11 are connected and the engine is by-passed. Switch 14 is closed and circuits to the heating device and fan 16 are made. Medium circulating in the engine by-pass circuit is heated at 10 and gives up its heat at heatexchanger 12 to air blown from fan 16 into the vehicle's interior. In a modification, a switch is provided in which in position I, the circuit to the heating device 10 is broken and in its place the circuit to the fan 16 is closed. In this way the vehicle interior is heated independently of the heating device by the engine 1. In a simplification of this latter modification only a means for switching-off the heating device is required, the air being forced into the vehicle's interior by the draught as a result of the movement of the vehicle.

Title: Improvements in and relating to methods of conditioning anodes for x-ray generating apparatus
IPC: H01J35/10
Filed: 1942-06-04
Abstract: 560,815. Rontgen-ray tubes. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.) June 4, 1942, No. 7636. [Class 39 (i)] [Also in Groups II and XXXVI] The anode of an X-ray tube is made resistant to cracking by first polishing it and then subjecting it to an aging process by progressively increasing its temperature to promote slow crystallization of the anode material. The polishing is preferably performed by an electrolytic process in a bath of sodium hydroxide and sodium carbonate. Full details of temperature, concentration and current density are given. An oxide coating is produced which is removed by immersing the anode in hydrochloric acid. The aging process consists in subjecting the anode when mounted in the tube to a series of electron bombardments, starting at one half of the rated capacity and finishing at a load in excess of the operating load, periods of rest being allowed between each bombardment. Full details of times and loads are given. At the same time occluded gases are removed from other parts of the tube. As part of the conditioning of the tube, a gettering process may be carried out before or during, but preferably after, the aging process. To prevent deposition of gettering material upon the electrodes, it is contained in a nearly closed pocket within either the anode or the cathode. In one form the anode F, Fig. 3, has a dependent skirt which surrounds the bearings 37, which in turn are supported from a cup-shaped member 27 sealed to the glass stem R. The gettering wire 19 is mounted between the bearings and is heated by an independent lead 30. In this form the gettering material is also deposited upon the bearings 37 and serves as a lubricant therefor. The anode is rotated during this process. In another form the cathode C, Fig. 6, has a depending skirt 55 which contains the gettering wire 19 supported on the central, post 26 within which passes the independent heating lead 30. Two filaments 49 are provided. The gettering wire comprises a tube 19, Fig. 8, containing the gettering material 33 and flattened at one side 21 so as to present a thin wall portion through which the material evaporates on heating. Sufficient getter material may be left to enable reconditioning of the apparatus to be carried out during its working life. Specifications 411,503 and 542,665, [Group II], are referred to.

Abstract: 1,008,013. Colour reversal processes; colour developers. ILFORD Ltd. Feb. 14, 1964 [Feb. 26, 1963], No. 7765/63. Heading G2C. In a photographic colour reversal process wherein the residual silver halide is rendered developable by treatment with an alkali metal borohydride (see Specification 904,462), the borohydride is added to the colour developing solution. The invention may be used for the reversal of colour material in which the colour couplers are incorporated into the layers of the material. Where the colour couplers are not included in the material, the layers are selectively reexposed and developed in a colour developer containing the appropriate colour coupler in the usual way, except that the re-exposure of the last layer (e.g. the green-sensitive middle layer) is omitted, and an alkali metal borohydride is added to the final colour developer (containing the magenta colour coupler).
