Title: Device for separating in a solid state components from a gas mixture by cooling and gas separating plant provided with one or more of these devices
IPC: F25J3/08
Filed: 1962-09-18
Abstract: A gas mixture is cooled in order to separate a component in a solid state in a device comprising cooling members arranged between, and in heat-conductive relationship with, two spaced layers of gas-permeable material, wherein the gas mixture flows partly through one layer and partly through the other layer into the space between the two layers. In the case of a gas mixture which contains water-vapour, snow is deposited on both layers of gaspermeable material. As shown, a gas mixture to be rectified is introduced through aperture 52 into a vessel which contains four devices 49 each comprising a row of cooling tubes on each side of which a layer of metal gauze is soldered. The gas mixture passes in the direction of the arrows 9 through the devices where the water-vapour solidifies as snow on the layers of metal gauze. The dried gas mixture flows through ducts 48 and filter 47 whence it passes up pipe 53 into an annular channel 42 surrounding a rectifying column, the lower part of which is shown at 41. The column is provided with insulating material 43. The liquid fraction leaving the base of the column through pipe 45 enters container 46, and then flows via pipes 50 into the cooling tubes of the devices 49. The liquid boils as it rises up these tubes, and the vapour is returned to the column via ducts 51.

Title: Process for molding hollow,shaped articles of polytetrafluoroethylene
IPC: B29C43/12
Filed: 1965-08-18
Abstract: In the production of hollow articles, a powdered sinterable material e.g. polytetrafluoroethylene, is held between the inner walls of a rigid mould and the outer walls of an elastic counter-mould of thermoplastic material, and the powder is then compressed by expansion of the counter-mould by passing thereinto fluid under superatmospheric pressure, causing agglomeration of the powder. The countermould and agglomerated preform are removed from the rigid mould, heated whereby the counter-mould may be removed from the preform either manually after softening or by melting, and the preform is then sintered. The powder may be of size 30-625 preferably 50- 625 mesh A.S.T.M., and may be mixed with metal powder, glassfibre or graphite. The counter-mould may apply a pressure of 50- 350 atm., e.g. 100-300 atm., preferably 240- 260 atm., for a period of 0À5 to 5À0 min., preferably 1-2 min. and may be made of thermoplastics material which has a melting-pt. between 100 and 170 C., and which may be plasticized or unplasticized polyethylene or a polyvinyl chloride. The sintering temperature may be 300-400 C., preferably 360-380 C. Tapering hollow bodies may be made having an opening at the narrower end. The apparatus consists of an outer rigid casing having a plugged opening to hold the counter-mould edges against the outer casing, the plug being bored for the passage of fluid. The inner surface of the outer casing may be in 3 pieces: a tapering piece nearest the opening, a cylindrical piece attachable thereto, and a lid attachable to the cylindrical piece.

Title: Method of standardizing the output voltage of permanent magnet control alternators
IPC: H01F13/00
Filed: 1967-10-21
Abstract: The permanent magnet armature 9 for a tachometric alternator is partially demagnetized by feeding to the stator windings 8 a source of alternating current of increasing intensity, the armature being driven at such a constant speed by motor 10 that the frequency of the alternator current is different from the source of A.C. The intensity of the source of A.C. from 3 is varied using a motorized autotransformer 4 or a saturable inductance. Periodically the output voltage of the alternator is measured automatically by device 11 which switches contact 6 to a voltage meter 12 and controls the motion of autotransformer 4. A number of alternators having identical voltage outputs may be made in this way. If the alternator is used for controlling gear changes in an automobile, the stator poles are positioned to correspond to the maximum engine load and the speed of motor 10 corresponds to that selected for a gear change.

Title: Method of manufacturing a cam for use in an ignition distributor
IPC: F16H53/00
Filed: 1969-01-08
Abstract: An ignition distributer cam is manufactured by (i) grinding the cam to the desired profile, to leave the cam surface with sharp edged asperities defining therebetween channels which in use store lubricant (ii) placing the cam in a container with abrasive particles and (iii) moving the container so that the particles collide with the cam surface and round off the sharp edges without removing the asperities. This is stated to reduce the wear rate of cam followers made of synthetic resin. Distributer cam-shafts having cams ground to the desired profile, are treated in a vibratory finishing machine, e.g. one having an annular bowl 11 of generally semicircular cross-section filled with ceramic particles in the form of prisms. The bowl is spring mounted and is caused to vibrate in such manner that the prisms progress around the bowl from the lower portion 12 thereof in a substantially toroidal helical path towards the outlet 13 from the bowl. A small amount of soapy water is added to the bowl.
