Filed: 1943-04-03
Abstract: 565,511. Filters. PICKARD, J. A., and METAFILTRATION CO., Ltd. April 3, 1943, No. 5372. [Class 46] A filter system for lubricating oil comprises a pump supplying oil past a non-return valve to a filter having associated therewith an air chamber at the unfiltered oil side, whereby air pressure built up in the air chamber maintains the flow of oil in the same direction through the filter when the pump is stopped. The air chamber may be external to the filter chamber or provided by a space therein located above the filter elements. The filter elements may be of the edge type, but, as shown, the filter elements 8 are of the porous leaf type comprising annular cells 9 formed by pairs of elements joined at the outer edges and spaced apart at the inner edges by washers 11 with radial grooves therein to form channels, whereby the annular cells 9 communicate through apertures in a tubular member 10 with the delivery space formed around a rod 13 and leading by a cross channel 31 in such rod to a bore 30 and so to the discharge conduit 32. The rod 13 has screwed ends and serves to retain the closure cap 20 which is formed or fitted with a bell 4 to form an air compression space located above the filter elements. A spring 23 acting on a washer 24 and felt packing ring 26 presses on a bell-shaped member 25 to force the filter elements tightly against each other. Lubricating oil to be filtered is supplied by a pump past a non-return valve 3 to the outside of the filter elements and rises to compress the air in the compression bell 4 ; filtration is effected by passing through the porous leaves and this will be continued under the air pressure in the compression space when the pump is stopped as on stoppage of the internalcombustion engine for which the lubricating oil is being supplied. The arrangement is of use where such engine is used on short runs. Specifications 432,102 and 469,152 are referred to.

Patent GB-687629-A (GB)
Title: Production of seambless hollow rubber articles
Filed: 1951-03-06
Abstract: Seamless hollow structures are produced by subjecting a solid blank of vulcanizable material to a vulcanizing treatment so as to cure the outer layers of said blank while leaving a substantially uncured inner core, and separating the cured layers from the core thereby converting said blank to a seamless hollow structure. Preferably a thin solid blank is made from a solution or a latex of natural rubber containing vulcanizing ingredients and the blank is then heated to 80-90 DEG  C. in a water bath containing an accelerator such as hexamethylene tetramine or tetramethylthiuram sulphide until superficial vulcanization is effected.  The blank is then treated with a solvent such as benzine, benzene, toluene, xylene, methylene chloride, chloroform, carbon tetrachloride, methanol, ethanol, or cyclohexane until some of the solvent p  penetrates into the central unvulcanized portion; on raising the temperature rapidly, the solvent volatilizes rapidly thus causing expansion to form tubing, football bladders or bulbs. Alternatively the unvulcanized core may be forced out of the partially vulcanized blank by means of rollers, or after partial vulcanization air is injected into the unvulcanized portion in order to produce expansion.

Abstract: 383,134. Centrifugal machines. GRAUSS, G., 21, Boulevard Port Royal, Paris. Feb. 25, 1932, No. 5621. Convention date, June 13, 1931. [Class 23.] A centrifugal machine for purifying paper pulp and like material has a removable bowl b, as described in Specification 212,551, [Class 23, Centrifugal machines &c.], driven through a centrifugal clutch. The material is supplied through an inlet k which is curved at its inner end to give the pulp a whirling motion as it enters the distributer h. A baffle ring i is placed at the bottom of the distributer, and the pulp is disintegrated by impacts on the ring i and the flange h<1>. It then passes into the space l, from which it passes through the spaces of the sieve f into the bowl b. The heavy impurities are thrown to the wall and retained there, while the light impurities are held by the member e. The purified pulp passes through the gap between the members d, e and is deflected by the crown p into the outlet gutter q. An adjustable suction device n is used to draw off the light impurities. Shoes m on the hood d engage in inclined ports in the flange e, so that rotation of the flange varies the gap between the members d, e through which the purified pulp passes.
