Abstract: 530,375. Indiarubber compositions. DISTILLERS CO., Ltd., STAUDINGER, H. P., and HUTCHINSON, H. M. May 9, 1939, No. 13861. [Class 70] [Also in Group IV] Polymerization products, which can be moulded or pressed into sheets, are prepared by heating a mixture of styrene and rubber with a crotonic ester, e.g. vinyl crotonate or ethylene glycol dicrotonate with or without an α-alkyl styrene, e.g. α-methyl styrene. The rubber component, either in the form of crepe rubber or masticated rubber, may be dissolved in the styrene or in a solvent common to the styrene and the other component or components, e.g. benzene or isopropyl benzene, or the rubber may be in latex form, in which case the mixture is polymerized as an emulsion. The polymerization is preferably effected in the absence of air, e.g. in an atmosphere of nitrogen. Plasticizers, e.g. low molecular weight polymers of an α-alkyl styrene, may be incorporated in the mixture before or after polymerization. In an example, a mixture of crepe rubber, styrene, isopropyl benzene and ethylene glycol dicrotonate, is heated in an atmosphere of nitrogen. According to the Provisional Specification, the mixture comprises styrene, rubber, and an ester of an unsaturated acid with or without a vinyl aromatic hydrocar- 'bon other than styrene. Specification 11397/38 (as open to inspection under Sect. 91) is referred to.

Patent GB-1508975-A (GB)
Title: Variable-speed transmission systems
IPC: F16H3/66
Filed: 1974-03-30
Abstract: 1508975 Change-speed gear WILSON MILLER & CO Ltd 27 March 1975 [30 March 1974] 14223/74 Heading F2D Clutches C1, C2 connect suns S1, S2 of a planetary gear set with the output member 12 of a hydrodynamic torque transmitter T, which may be a converter with a reaction element 13 mounted on a unidirectional sprag clutch 17, as shown, or a two-element coupling, a third clutch C3 connects a planetary carrier L<SP>1</SP> through a central shaft 28 with the input member 11 of the transmitter, as shown, or with the output member 12, a ring gear A1 is connected with the final output member 24, and carrier has pinions P1 in mesh with the ring gear and with the sun S2 and also with further pinions P2 which mesh with the sun S1. The sun S2 and the carrier have brakes B2, B1 which in common with the three clutches may be operated by oil pressure, and a unidirectional sprag clutch (not shown) may be connected between the carrier and the fixed housing of the transmission to facilitate smooth transition from first to second ratio. First ratio is established by engagement of the clutch C1 so that drive is transmitted from the member 12 to the sun S1 and thence through the pinions P2, P1 to the ring gear A1, reaction on the carrier being taken by the sprag clutch. If engine braking is required the brake B1 is applied. Release of brake B1 and application of brake B2 to hold the sun S2 establishes second ratio, and engagement of both clutches C1, C2 with both brakes released locks the planetary train to establish direct drive. If the clutch C3 is engaged also the torque transmitter is by-passed provided the shaft 28 is connected as shown to the input member of the transmitter rather than to the output member 12. An alternative mode of establishing direct drive is by engagement of the clutches C1, C3 only to divide the torque into two paths between the transmitter and the output member 24. Overdrive is established when the clutch C3 and brake B2 are applied and reverse when the clutch C2 and brake B1 are applied. In a modification, the ring gear is attached to a spur wheel situated between the clutch C2 and the planetary set and meshing with a further spur wheel driving a pair of output shafts through a differential gear. Further modifications incorporate a second ring gear in mesh with the pinions P2 and engageable by a brake to provide an additional ratio.
Patent GB-745892-A (GB)
Title: Improvements in or relating to electrically conductive elements
IPC: H01B1/22
Filed: 1951-06-15
Abstract: A conductive element is formed by depositing a porous metal layer on a porous flexible base, impregnating the layer with a dielectric material, and removing the base from the layer either before or after the impregnation.  The base may consist of paper or asbestos fibre sheet; the metal may be sprayed, or deposited in solid or molten condition, or by sintering a layer of metal powder, and is preferably thin enough to pass light.  It may be deposited on one or both sides of the base.  Removal of the base may be by combustion, solution or mechanical separation.  The metal layer may be rolled or ground smooth, and impregnated with molten wax, varnish, enamel, celulose acetate, urea-formaldehyde or phenol-formaldehyde or other liquid or solid dielectric material.  Impregnation may be effected by passing the layer through a pressurised extrusion machine head to provide a uniform coating of plastic material.  The electrode may be used for capacitors or coils, and may be interleaved with spacers; impregnation may be effected after the electrodes and spacers are wound or otherwise assembled.  Non-inductive windings may be used, and the electrode strips may be extended to provide terminals.

Abstract: 102,718. Soc. Anon. pour l'Exploitation des ProcÚdÚs Westinghouse- Leblanc. Dec. 13, 1915, [Convention date]. Blast and aspirating apparatus, ejector.-Relates to the condensation of the working fluid of steam-ejectors used for such purposes as the extraction of air from steam-engine condensers, and consists in avoiding the shocks and noises on discharge into water such as occur with apparatus of the type described in Specification 7678/14. The ejector exhaust pipe a, Fig. 1, at its extremity within, say, a feed-water tank b, is provided with a shellshaped piece c pierced with holes d parallel to the axis e. According to another method, the steam passes from an annular chamber through inclined apertures into the pipe conveying water from the pump, thereby assisting the flow. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement wherein the steam, entering bv the pipe g, Fig. 2, (cancelled), is condensed in a simple form of jet condenser f, supplied with water coming by the connexion h from a pump removing condensed steam from the main condenser, the products of. condensation passing to the feed-tank i. When the pump is not working there may be a special supply of condensing-water from the pipe k. Alternatively a surface condenser is substituted for a jet condenser, or the ejector may discharge into a water-jet condenser of the K÷rting type, arranged in the feed-water tank. This subjectmatter does not appear in the Specification as accepted.
