Title: Gas Cushion Vehicle
Inventor: MOORE ROBERT GRANVILLE
IPC: B60V1/00
Filed: 1966-03-08
Abstract: 1,178,704. Air cushion vehicles. HOVERCRAFT DEVELOPMENT Ltd. 21 Feb., 1967 [8 March, 1966], No. 10119/66. Heading B7K. An air cushion vehicle provided with a cushion compartmenting wall has means which deflect a gas discharge nozzle in the wall in a direction to discharge gas into a compartment in which gas pressure is increased when the vehicle tilts, thereby assisting restoring action. In Fig. 9 a nozzle 31 in a compartmenting wall 20 is connected to vehicle structure by flexible or rigid ties 38 which, when the wall is deflected laterally by increased pressure in compartment 1 3a due to tilting of the vehicle, cause the nozzle to be so inclined that it discharges into compartment 13a to increase the pressure therein. In Fig. 11, a nozzle 31, continuously supplied with gas from duct 19 to form a gas curtain, is rotated by a powered unit in a housing 40, the unit being energized to operate in the appropriate direction by pressure-responsive devices 48, 52 or 49, 53 so that the gas curtain is deflected towards the part of the cushion subjected to increased pressure by tilting of the vehicle.

Title: An improved process of and apparatus for the separation of gas mixtures by liquefaction
IPC: F25J3/08
Filed: 1943-06-19
Abstract: 565,165. Separating gases by liquefaction. LINDE AIR PRODUCTS CO. June 19, 1943, No. 10204. Convention date, June 5, 1942. [Class 8 (ii)] In the low-temperature separation of gaseous mixtures, such as air, containing less volatile impurities such as hydrocarbons, the gas mixture, cooled and containing a substantial amount of liquid, is treated in a scrubber 21 from which the liquid containing the impurities and the gaseous portion are withdrawn separately, and the liquid is passed through a pipe 26 into a vaporizer 28 where it is vaporized, after expansion through valve 26<1>, by the gas passing through a coil 30. Impurities are removed through a drain 31. Another portion of liquid from the scrubber passes through an expansion valve 27<1> to a vaporizer 29 wherein it is vaporized, with removal of impurities in liquid form through a drain 41, by a coil 33 conveying the vapour from vaporizer 28 and that from coil 30 expanded through a valve. Some liquid from vaporizer 28 may bo passed into vaporizer 29 through a valved pipe 127. The vapour from vessel 29 and the partly condensed vapour in coil 33 after expansion are passed by a pipe 35 into the first stage of a rectifier..The air to be separated may be delivered by a compressor 10 through a heat exchanger 12, where it warms nitrogen delivered from the rectifier ; part then flows through a second exchanger 18, also traversed by the nitrogen; and part flows to an expansion engine 16, the exhaust being cooled in an exchanger 57 by the nitrogen and passed to the second vaporizer 29. In a modification, the coil 30 is connected to the pipe 35 in parallel with the coil 33 and does not enter the vaporizer 29, and an adjustable byepass for the heat exchanger. 57 connects the nitrogen delivery pipes 56, 58. The air may alternatively be supplied by separate compressors, respectively compressing atmospheric air to higher and lower pressures.

Title: Improvements in or relating to a coupling connecting a handle to the rotatable stem of a valve
IPC: F16B1/00
Filed: 1963-03-15
Abstract: 1,033,402. Valves; positive clutches. FMC CORPORATION. March 15, 1963 [April 2, 1962], No. 10297/63. Headings F2C, F2L and F2V. [Also in Division G3] A self-closing valve 14, Figs. 1 and 2 and Figs. 4 to 12 (not shown), is opened by a handle 96 through a coupling 16 which can be released by fluid-pressure operated diaphragm means 30, 60 to allow the valve to close automatically. The coupling comprises a first coupling element 46 fixed to the valve stem 40 and a second, rotatable coupling element 70 fixed to the handle 96. One element, 46, has inclined slots 48, 50 to accommodate balls 56, 58 which can enter recesses 84, 86 in the other element to positively engage the drive when the diaphragm 30 is pressurized. The device is applied to a known apparatus commonly termed a " loading arm," Fig. 1, for filling tanks with petrol. This arm comprises a filling pipe 10 and a vapour recovery pipe 11 constituting a pivotable arm carrying a head 12 which engages the tank. A control valve, not shown, operated by a float 17 in the head 12, releases pressure from the diaphragm 30 through pipe 18 when the desired level is reached, to disengage the coupling 16. Additionally, a control valve, not shown, which is operated when the head makes proper contact with the tank, or breaks contact with it, also releases pressure from the diaphragm 30. The handle 96 is urged to closing position by a spring 105 connected as in Fig. 7 to the head 70. Normally the opening movement of the handle is limited by a stop 102, Fig. 2, on a fixed housing 19 which is engaged by a spring-biased pivoted dog 100 on the handle. This dog can be moved out of the way of stop 102 to enable the valve to be opened further if desired. A lost motion connection, Fig. 6, is provided between the coupling elements, whereby the valve 14 can be positively opened or closed by the handle 96 whether the coupling 16 is engaged or not. Two pins 112, 113 fixed to element 46 occupy the full line position, Fig. 6, when the coupling is engaged and the handle in valve open position. If the coupling is released, element 46 will normally rotate to valve closed position, moving pins 112, 113 to the broken line position. Should the valve fail to close, movement of the handle will effect positive closure owing to engagement of a pin 114, fixed to element 70, with the pin 113. Similarly, " tapping off " of the tank can be effected. Coupling element 70 is mounted by a ball bearing 72 filled through an opening 78. In a modification, the handle extends from the periphery of coupling element 70 and is biased by a coil spring connected to the housing of valve 14. A releasable safety chain extends through this spring to limit the opening movement or allow a greater opening movement when this chain is released.

Title: Improvements in or relating to cleaning and washing agents having bleaching properties
IPC: C11D9/42
Filed: 1956-04-05
Abstract: A perborate-containing detergent composition, which is relatively stable against gravitational separation of perborate during handling, is produced by subjecting a mixture of soap, or an anionic or non-ionic detergent, in granular form with sodium perborate tetrahydrate crystals to a temperature above 145 DEG  F., generally 150-230 DEG  F., for a length of time sufficient to melt the perborate crystals, preferably for not more than one minute, and then, before substantial decomposition of the perborate occurs, cooling the resulting product to a temperature below 145 DEG  F., as a result of which the resolidified perborate becomes coated on the surface of the detergent granules.  The process may follow immediately after a spray-drying process for a slurry of the detergent mixture.  The detergents, in addition to soap, which may be used include alkyl sulphates, fatty acid monoglyceride sulphates, alkylbenzene sulphonates, fatty acid monoesters of low molecular weight hydroxy- or polyhydroxyalkane sulphonic acids, alkyl glyceryl ether sulphonates, alkyl ethers of poly-oxy-ethylene sulphates, and alkyl phenol-ethylene oxide condensates.  The perborate generally comprises 5-20 per cent of the detergent by weight.  Other adjuncts which may be incorporated are tripolyphosphates, silicates, carbonates and alkylolamides; cocoanut oil alcohol is also used in an example.
