Title: Improvements in or relating to vacuum rectifiers
IPC: H01J13/28
Filed: 1921-05-17
Abstract: 163,325. Siemens - Schuckertwerke. May 15, 1920, [Convention date]. Low-pressure metallic-vapour apparatus.-In a mercury or other rectifier, the flow of vapour causes a suction of air and residual gas from the anode spaces, thereby improving the vacuum near the anodes. As shown, a double-walled cylindrical or other screen 7 and deflector 9, arranged above the cathode 5, provide a down. ward path 11 for the vapour, which draws gases in the direction shown by the arrow 12, away from anodes 2, and towards a discharge pipe 13. The container has a water jacket 10, and the anodes are mounted in extensions 3 of the container, and provided with protective tubes 4. An insulating ring 6 is arranged between the cathode and the container. Condensed mercury 8 overflows to the cathode.

Title: Apparatus for removing volatile impurities from lubricating oil
IPC: C10M175/00
Filed: 1971-05-07
Abstract: 1350126 Evaporators, film-type; purification of lubricating oils G R PRIEST 7 May 1971 [2 Dec 1970] 13825/71 Headings B1B and B1D Volatile impurities such as water are evaporated from lubricating oil by causing it to flow in the form of a thin film over concentric annular tiers 35, 36, 37 while heating it to about 200F. by inverted dish-shaped electrical resistance heater 45. The vapours leave the evaporator chamber through vent 44; and the purified oil flows out through conduit 40. The oil to be purified is forced into the base of the apparatus through inlet 13, and rises through fibrous filter material 14 and felt pad 15. The oil then flows up capillaries 33 and expands through cups 34 whereupon it is demulsified and distributed over the evaporator tiers. In a modified apparatus, the heating element is embedded in the cap, so that more uniform radiation of heat is achieved (Fig. 4, not shown). An apparatus is also described wherein heat is conveyed to the tiers by conduction. The apparatus may be connected to the recirculatory oil system of an internal combustion engine.

Abstract: 1358551 Colour television RCA CORPORATION 1 May 1972 [7 May 1971] 13859/71 Heading H4F A PAL colour television receiver is modified to receive SECAM (Registered Trade Mark) colour television signals. The demodulated SECAM signals are passed to an amplitude modulator 7 which also receives an input from the PAL reference oscillator 9 via a switch 14 and 90 degrees phase shifter 12, so that the R-Y signal is modulated at 0 degrees phase and the B-Y signal at +90 degrees phase. The signal from the modulator 7 is passed to the PAL demodulation circuitry including a oneline delay line 15 which causes a 180 degree phase shift in a received signal. The R-Y and B-Y signals are then produced at the outputs of demodulators 26, 19. The received SECAM. R-Y and B-Y signals are frequency modulated on to subcarriers at different frequencies and may originally be demodulated by two frequency discriminators or by one frequency discriminator 5 which has its centre frequency changed line by line.

Title: Improvements in and relating to steam power plants
IPC: F01K17/00
Filed: 1964-04-03
Abstract: 1,055,717. Direct contact steam boilers. ATLAS-WERKE A.G. April 3, 1964 [April 3, 1963], No. 13891/64. Heading F4A. [Also in Division F1] A steam turbine plant comprises a boiler 3 supplying a turbine 4 exhausting to a combined steam accumulator and feedwater storage tank 1. Steam from the accumulator 1 flows to a pre-heater 9 associated with a multistage vaporizer 10 and the condensate is returned by a pump 11. The accumulator 1 comprises inlet and main chambers 14, 16 respectively separated by a partition 15. The chambers 14, 16 are in steam communication by a passage 17 and water communication by a passage 18. Steam enters chamber 14 through vertically mounted pipes 12 having openings 13. According to the loads on the turbine and the resulting steam pressure, the level of water in container 14 varies, thus reducing steam pressure fluctuations in pre-heater 9. Steam introduced through openings 13 above the water level flows through passage 17 into chamber 16 while that introduced below the water level condenses. When the turbine load is high most of the water is blown out of container 14 and is caught in a receiving space 19 from which it flows to the bottom of chamber 16 through a pipe 20. A sudden decrease in turbine load causes evaporation of water in chambers 14, 16. In modifications, a direct connection is also made between turbine 4 and pre-heater 9, the inlet and main chambers 14, 16 are separate, and pipes 12 are horizontally mounted.

Title: Improvements in or relating to the Marginal Folding and Perforation of Boot or Shoe Uppers.
IPC: A43D8/40
Filed: 1918-08-27
Abstract: 131,724. British United Shoe Machinery Co., (United Shoe Machinery Corporation). Aug. 27, 1918. Folding edges of sheet material.-Consists of a machine for simultaneously folding and perforating the edges of boot uppers. The upper 100 is supported on a resiliently mounted stripper-plate 13 provided with perforations registering with fixed tubular punches 11. The machine is operated from eccentrics 27 driven through a single-revolution clutch. During the ascent of a cross-head 21, the work is clamped by spring presser-rods 43 and is engaged on the edge to be operated upon by a creaser 31, over which the edge is folded by a folder 69. During the descent of the cross-head, the creaser 31 and folder 69 are withdrawn from the fold and the work is forced on to the punches 11 by a punch block 91. The movements of the creaser and folder are controlled, respectively, by spring latches 59, 71 pivotally supported on the crosshead and adapted to co-act with adjustable bolts &c. The presser-rods 43 are raised by the latch 59 during the ascent of the cross-head to its normal position. Stops 89 are provided on the folder to facilitate the positioning of the work. According to the Provisional Specification, the edge of the work may be coated with cement prior to insertion in the machine.

Title: Brake systems in vehicles having fluid pressure operated propulsion control circuits
IPC: B60T11/10
Filed: 1973-03-22
Abstract: 1423387 Spring applied brakes CATERPILLAR TRACTOR CO 22 March 1973  [23 March 1972] 13919/73 Heading F2F A vehicle has a fluid pressure operated propulsion control circuit for controlling the propulsion of the vehicle, a source of pressurized fluid for the circuit, a brake system comprising resilient means biasing a brake into an engaged position, a piston mounted in a cylinder and operable under the action of pressurized fluid from the said source to automatically release the brake upon initiation of drive of the vehicle by the propulsion control circuit, and a valve system arranged to permit the pressuzed fluid to act on the piston only when it is above a predetermined minimum pressure whereby to prevent undesirable partial release of the brake. As shown, an excavator has a drive circuit comprising two track driving motors 18, 20 controlled by valves 54, 68 which determine the direction of rotation of the motors. Associated with each motor 18, 20 is a spring applied, hydraulically released brake actuator 90, 92 fed from a pump 84 via a valve 300. To completely overcome the spring force for each actuator, the fluid pressure must attain a minimum value and to avoid partial application only, if this value is not attained, a saver valve 302 is biased by a spring so that fluid in a line 322 flows to a tank. This causes the valve 300 to be spring biased to cause the brake fluid to flow also to a tank thus producing full brake application. If the fluid pressure is high enough to overcome the brake springs, fluid flowing in line 318 passes to the valve 300 to bias it to allow fluid to flow to the brake actuators 90, 92, the saver valve being biased by fluid in a line 320 from the pump 84. Fluid in line 318 does not flow from a three-way check valve 314 when pilot control valves 40, 41, controlling the valves 54, 68 respectively, are actuated so that the valves 54, 68 only return fluid in the drive circuit back to a reservoir 46. When the valves 54, 68 are actuated by movement in either direction of the motors 90, 92, fluid flows from the valves 40, 41 so that the brakes are released.
