Patent GB-160808-A (GB)
Title: Automatic obturator for compressed air brakes, especially intended for long trains
IPC: B60T15/46
Filed: 1921-03-29
Abstract: 160,808. Seguin, E. March 30, 1920, [Convention date]. Fluid - pressure. - V a l v e mechanism for preventing the too sudden rise of pressure in the brake cylinders at the head of long trains comprises in one fcrm, Fig. 1, a casing interposed between the auxiliary reservoir B and the triple valve and containing a piston C subject on its upper face to the pressure in a chamber H which is supplied through a spring- pressed valve f so that a pressure is established therein a predetermined degree less than the initial pressure in the auxiliary reservoir and the chamber a falls sufficiently to permit the pressure in the chamber H to overcome the spring D, the piston C closes the passage i<1> and the brake cylinder is then supplied only through the restricted passage i. The valve may be cut out by opening a connection between the chamber H and the reservoir B or by means of a by-pass as described below. In another form, described in the Specification as open to inspection under Sect. 91 (3) (a) the fluid pressure on the two sides of the piston C normally equalizes through the port d'. When, in an application the triple valve connects the pipe b<1> to the brake cylinder, the fall in the pressure in the chamber a<1> causes the piston C to uncover the ports c' so that air is supplied therethrough as well as through the port d<1>. The spring D however returns the piston when the pressures in the chambers a, a<1> have sufficiently equalized and permits only a slow further increase in the brake cylinder pressure through the port d<1>. If the brakes are applied in stages the valve operates at the beginning of each stage. The valve may be cut out by a cock F in the by-pass F. This subject-matter does not appear in the Specification as accepted.

Title: Polymerization products, and the production thereof
IPC: C08F236/04
Filed: 1956-03-26
Abstract: Copolymers of (1) a conjugated diolefinic hydrocarbon or monohalogen substituted derivative thereof and (2) an a ,b -ethylene dicarboxylic acid derivative having a free carboxyl group or maleic anhydride, in which the molar ratio of (1) to (2) is 1:1 to 2:1, may be prepared by polymerization in a homogeneous phase in the presence of a free radical forming substance.  Specified diolefines are butadiene, isoprene, 2,3-dimethyl butadiene and chlorobutadiene.  The acid derivatives may be the half esters, half amides or substituted half amides of maleic, fumaric, itaconic or citraconic acids, e.g. the monomethyl, monoethyl, monobutyl, monohexyl, monododecyl, mono-octadecyl, monophenylethyl and monocyclohexyl esters of maleic and fumaric acids, N-isopropyl monomaleic amide and N-dodecyl monomaleic amide.  Additional comonomers, e.g. the diesters and diamides of the aforementioned acids such as dioctadecyl maleate, vinyl acetate, acrylic and methacrylic esters of aliphatic or cycloaliphatic alcohols containing 1 to 18 carbon atoms such as methyl, ethyl, isopropyl, octadecyl and cyclohexyl acrylates and methacrylates, isobutylene, styrene, a -methyl styrene, p-chlorostyrene, vinyl chloride and vinylidene chloride may be present.  Polymerization may be effected in bulk or in solution, e.g. in butanol, ethyl acetate, butyl acetate, benzene, toluene, xylene, cyclohexane, benzine, dioxane, acetone and methyl ethyl ketone.  The catalyst may be benzoyl peroxide, lauroyl peroxide, tertiary butyl hydroperoxide, azodiisobutyronitrile or redox system.  The acid derivative, optionally with the additional monomer, may be preheated with the catalyst and the diolefin thereafter added, preferably at the rate at which it is polymerized.  The products may be esterified with alcohols, e.g. methyl and octadecyl alcohols, converted to salts by adding alkali and may be rendered insoluble by reacting with polyamines or polyhydric alcohols, e.g. ethylene diamine, diethylene triamine, trimethylol propane and pentaerythritol, if desired in the presence of a vulcanizing agent.  The products may be used for impregnating leather and textiles, coating wood, metal and fabrics, as adhesives for glass and as plasticizers, lubricants or lubricant additives.  Examples describe the copolymerization of (1) mono-octadecyl maleate, dioctadecyl maleate and butadiene; (3) monomethyl maleate, styrene and butadiene; (4) and (5) monocyclohexyl maleate, styrene and butadiene; (6) maleic anhydride, styrene and butadiene; and (7) and (8) monobutyl maleate, styrene and chlorobutadiene.

Filed: 1964-03-05
Abstract: 1,100,331. Making casting-moulds; machine tool details. CHLORIDE OVERSEAS Ltd. 25 Feb., 1965 [5 March, 1964], No. 9419/64. Heading B3A, B3B and B3F. For producing thin castings having openings, e.g. grids such as battery electrode grids, a mould comprises two slabs 10, 11 with their adjacent faces, for forming the mould cavity, shaped concavely so as to leave a space which tapers to at least some of their edges, Fig. 2, so that when the melt such as hot lead is introduced, the concave faces expand, the adjacent faces become plane, Fig. 3 (not shown), and the slabs close together to give the mould cavity its required shape. Each slab is produced by bolting the edges to a straining block 12, Fig. 1, with a spacer 15 on it to render a face 16 convex. The bolts pass through holes in the block, Figs. 4, 6 (not shown), and screw into holes in the slab. The face is then machined flat as at 17 and the half-cavity form 18 cut on it before the slab 10 is released to allow the face 17 to resile to the required concave form. The spacer 15 may be placed eccentrically on the block in a keyway 21, Fig. 4 (not shown), or be contoured to produce a required curve form.

Title: Infinitely Variable Transmission System.
IPC: F16H47/04
Filed: 1967-03-01
Abstract: 1,157,480. Variable-speed gearing. WHITE MOTOR CORP. 1 March, 1967 [2 March, 1966], No. 9625/67. Heading F2D. Split-torque continuously variable ratio gearing, e.g. for earth-moving machines, includes a reversible hydrostatic transmission having variable displacement pump/motors 25, 26, and a sun-planet-annulus epicyclic train 30, 32, 28, and gives three contiguous speed ranges selectable by means of friction clutches. An input shaft 40 drives a pump 25 via gears 42, 44 and a shaft 45. An output shaft 72 is clutchable to planet carrier 32 by a clutch 78, or to annulus gear 28 by a clutch 82. For the first, lowest, speed range, clutches 78, 84, 86 are engaged so that the output shaft is clutched to planet carrier 32, and motor 26 drives sun gear 30 via a shaft 54, the clutch 86, and gears 56, 60, and drives annulus 28 via gears 62, 64, a shaft 65, the clutch 84, and gears 66, 52 (Fig. 1, not shown). For second range, sun 30 and planet carrier 32 are connected respectively to motor 26 and output shaft 72 as in first, but annulus 28 is driven from shaft 45 via a clutch 76 and gears 50, 52 (Figs. 2, 3, not shown). For lower third range, annulus 28 is clutched to the output shaft 72 by the clutch 82, planet carrier 32 is driven from shaft 45 via a clutch 80 and gears 46, 48, while motor 26 continues to drive sun 30 via clutch 86 and gears 56, 60. For upper third, the motor 26 drives sun 30 via a clutch 85 and gears 55, 58. To start from rest in first range, with maximum motor 26 displacement, the pump 25 displacement is increased from zero, the sun 30 and annulus 28 being rotated in opposite directions. When shaft 45 and gear 50 are synchronous, the clutch 76 is engaged and clutch 84 disengaged, to shift into second range. The pump 25 displacement is decreased to zero and then increased in the opposite sense to bring the sun 30 to rest and then accelerate it in the same direction as annulus 28. Shift to the third range occurs when the sun, planet carrier, and annulus are synchronized, the clutches 80, 82 being engaged, then the clutches 76, 78 disengaged. In the lower third range, the sun 30 is progressively decelerated to rest. Then the clutch 85 is engaged and the clutch 86 disengaged. In the upper third range the sun 30 is accelerated in the opposite direction to the rotation of carrier 32. Only in upper third is the motor 26 displacement reduced from maximum for final acceleration.
