Title: Improvements in compressors for brakes or hydraulic transmissions
IPC: F04B49/18
Filed: 1938-06-22
Abstract: 516,174. Hydraulic transmissions of power. SOC. ANON. DES ATELIERS GAMAIN. June 22, 1938, Nos. 18549, and 18550. Convention dates, June 23, 1937, and June 8, 1938. [Class 69 (ii)] [Also in Group XXXIV] A master cylinder for hydraulic brakes comprising coaxial high and low pressure pistons is provided with a valve adapted to connect the low pressure cylinder to the brakes, the low pressure cylinder also being connected with a space containing a piston sliding inside the low and high pressure pistons against a spring in order to vary the space so as to correspond to the pressure in the low and high pressure cylinders. Liquid is supplied to the brakes connected at 6 by both the high pressure piston 10 and the low pressure piston 9 operated by a driving member 14 until the pressures acting on the compensating pistons 26, 27 and valve 39 cause these parts to move and close the apertures 40 connecting the low pressure piston to the brakes. Liquid from the low pressure piston thus flows into the space 9<1> and the piston 27 moves in the interior of the low pressure piston 9 and fluid is forced therefrom into the reservoir connected at 7 by passages 29, 30, 31. Eventually a spring 35 engages the piston 27 causing resistance and eventually extension' 34 on the member 14 engages a cavity 33 in the piston 27. On release the pistons 9, 10 are returned by a spring 13 and the pressure of the fluid in the brakes. Fluid flows by a valve 53 from the reservoir to the low-pressure piston. The pistons are driven towards the left against the pressure of the spring 32 by the pressure of the fluid from the brakes to uncover the port 8 until this latter pressure has dissipated, when the pistons are moved to the right and port 8 closed to maintain a slight pressure on the fluid. A number of springs 35 may be provided, set back relative to one another. In a modification the communication between the low pressure and high pressure cylinders is by means of a port in the cylinder 3 in the release position and by a spring-pressed ball valve opening towards the high pressure cylinder. In a further modification, the compensating piston 27, Fig. 3, contains a valve 72 adapted to be opened by the member 14 to provide communication between the low pressure cylinder and the reservoir. The piston 27 carries a stem 37 on which is mounted a valve 61 having a packing 41 and controlling communication between the low and high pressure cylinders. When the piston 27 is moved back during brake application, liquid under pressure is released from in front of the low pressure piston into the reservoir, the piston 27 consequently returns and recloses the valve. This cycle is repeated until the pressure has attained such a value in the high pressure cylinder that the valve remains permanently open. A spring-pressed valve 81 maintains a slight pressure in the pipe lines.

Title: Improvements in and relating to sterilising machines and the like
Inventor: WEBSTER ALEXANDER HYDE
IPC: A23L3/04
Filed: 1952-07-23
Abstract: 730,781. Sterilizing-apparatus. WEBSTER & CO., Ltd., R. W. July 21, 1953 [July. 23, 1952], No. 18682/52. Class 49. In setting into operation a sterilizing-apparatus of the kind comprising a heated pressure chamber sealed by one or more water containing U-shaped conduits, the temperature and pressure within the chamber are raised by direct injection thereinto of a gas at suitable temperature, e.g. wet or superheated steam, independently of production of steam from the sealing water. The apparatus includes a heated chamber 1 sealed by water-containing, U- shaped inlet and outler conduits 2 and 3, heaters 9 for raising the temperature of the water in the sealing conduits, a steam-supplying nozzle 12 for heating the upper layer of water in the inner limb of the conduit 2, and a nozzle 11 to direct steam into the chamber 1 for maintenance therein of temperature and pressure at the values desired, the bottles or containers under treatment being carried by an endless conveyer 4 from a loading station 7 to an unloading station 8, and being cooled, if desired, by conveyance through a U-shaped, water-filled tank 5 and a water-filled trough 6. In setting the apparatus into operation, a valve 13 is open to allow steam from a source 10 to pass into the heaters 9 and so raise the temperature of the water in the sealing conduits 2 and 3 to a value, e.g. 190‹F., at which a thermostat 15 actuates a controller 14 to close the valve 13, and at the same time, to open a valve 16 to allow steam, also from the source 10, to pass by way'of a valve 17 to the nozzle 11 and so into the chamber 1. The increase of pressure within the chamber 1 causes depression of level of water in the inner limbs of the sealing conduits 2 and 3, and, when the pressure reaches a prearranged value, e.g. 61b./sq. in., a pressure-sensitive capsule 19 in the chamber 1 operates through a controller 18 to close the valve 17. At this stage the capsule 19 causes the opening, through a controller 24, of a valve 21 to admit steam to the nozzle 12 to heat the upper layer of the water in the inner limb of the sealing conduit 2, but when the temperature of this upper layer reaches a desired final value, e.g. 215 ‹F., a temperature-sensitive device 23 in this upper layer operates through a controller 22 to close a valve 20 and prevent further admission of steam to the nozzle 12, When the desired operating conditions have thus been reached, steam supplies to the nozzles 11 and 12 are adjusted by operation of the valve 17 by the controller 18, and of the valve 21 by the controller 24, under the influence of the pressuresensitive capsule 19, and by operation of the valve 20 by the controller 22 under the influence of the temperature-sensitive device 23. Specifications 377,890 and 648,345 are referred to.

Filed: 1970-04-21
Abstract: 1309143 Lamp failure alarms ITT INDUSTRIES Inc 21 April 1970 [25 April 1969] 18974/70 Heading G4N In a lamp failure alarm for a vehicle direction indicator using winking lamps repeatedly operated by a switch, a leakage path is provided across the switch and a control signal derived from the voltage across the lamps or the switch and used to change the frequency of winking in the event of failure of one or more lamps. As described, capacitor C charges via resistor R1 until the voltage at point A is sufficient to operate a threshold circuit SWS when an electronic switch S is set to its lower position so as to discharge capacitor C. This operation continues to repeat, and the resulting waveform is fed to a switching circuit AS which periodically closes the winking contacts S2 controlling the power to the direction indicator lamps L1, L2. The threshold of circuit SWS is controlled by the voltage across a leak resistor R2 halfway through the dark period, hence the frequency of winking will be doubled in the event of failure of one or both lamps L1, L2.
