Filed: 1939-02-01
Abstract: 524,595. Centrifugal gas cleaners. CORINTH, Ltd. Feb. 1, 1939, No. 3443. Convention date, March 11, 1938. [Class 23] Solid particles are separated from gas or vapour in a cyclone separator 10 having within it a chamber 16 provided with liquid spraying means 18 to moisten surfaces of baffles 17 passed by the gas stream on its way to the outlet 12. The gas enters the separator by the tangential inlet 13 and the coarser solid particles are thrown to the wall from which they fall to the outlet 15. The gas then passes to the cylindrical chamber 16 which has radial baffles 17 beneath the spraying device 18 consisting of nozzles 19 round the outlet tube 12. The baffles impede the rotation of the gas and the moistened solid particles are washed by the liquid spray to the bottom of the container and the outlet pipe 21. The liquid in the container rotates with the gas and assists the separating action. A cuff 22 in the outlet tube 12 prevents liquid from being carried up the tube by the gas flow.

Abstract: 1383439 Load responsive braking systems GIRLING Ltd 15 Jan 1973 [28 Jan 1972] 4239/72 Heading F2F In a dual hydraulic braking system in which a valve 13 or 14 is provided in each line of the system for varying the braking pressure according to vehicle load a transmission member receives the load responsive force and transmits it to the two valves, so that if the pressure in one line is lost the transmission member transmits the whole of the force to the functioning valve thereby increasing the brake pressure cut-in point at which the load responsive mechanism commences to regulate the braking pressure. In the embodiment shown the transmission member is a lever 10 which normally transmits the load responsive force L from a resilient member 12 equally to the pistons of valves 13, 14 through tappets, the lever being pivoted at 11. If the pressure in the line to which valve 14, for example, is connected fails, the valve 14 offers no resistance to the lever and the force applied to the other valve 13 is thereby doubled. In a further embodiment the valves are located sideby-side and the force transmission member is a torsion bar. An adjusting screw 16 is connected to the transmission member 10 to take up play between the member 10 and the tappets.

Title: Process for the production of new and useful polymeric materials
IPC: C08F8/30
Filed: 1945-02-21
Abstract: Polymeric alpha, beta-cyanoethyl ketones are obtained by reacting acrylonitrile, in the presence of an alkaline condensing agent, with a linear polymeric ketone of molecular weight of at least 1000, which has in the molecule an aliphatic carbon atom bearing at least two hydrogen atoms contiguous to a ketonic carbonyl group.  Suitable polymeric ketones are copolymers of ethylene and carbon monoxide, and of propylene, ethylene and carbon monoxide, methyl vinyl ketone polymer, methyl isopropenyl ketone polymer, ethylene/methyl vinyl ketone copolymers, copolymers of methyl vinyl ketone and butadiene or chloroprene, of benzalacetone and butadiene, and copolymers of methyl vinyl ketone with vinyl acetate, vinyl chloride, methyl methacrylate and vinylidene compounds.  The preferred ketones are those soluble in organic solvents.  The reaction is best carried out by dissolving the ketone polymer in an inert solvent, e.g. dioxan or ether, and the acrylonitrile and alkaline agent added slowly with agitation, the mixture being kept at a temperature between 0 DEG  and 75 DEG  C. Suitable alkaline condensing agents are sodium ethylate, sodium methylate, potassium hydroxide, sodium hydroxide, tetramethylammonium hydroxide and trimethylbenzylammonium hydroxide.  The products may be readily hydrolysed with the evolution of ammonia, and are stated to be useful as insecticides, and with aldehydes, alone or with a urea, phenol or amine, to form thermosetting compositions; and as intermediates in the preparation of polymeric amides, carboxylic acids, esters, amines, amidines, aminoacids, cyanoacids, aminoalcohols and thioamides.
