Title: Wheel rims
IPC: B60B21/06
Filed: 1961-11-20
Abstract: 932,986. Spoked-wheel rims. WEINMANN A.G. Nov. 20, 1961 [Nov. 18, 1960], No. 41468/61. Class 144 (2). A spoked-wheel rim comprises a light metal extrusion 2 having a recess 4 in its rim base portion 3, the edges 6 of the recess being undercut, and a band 1 of harder metal, such as stainless steel, secured in the recess by engagement of its chamfered edges 5 within the undercut edges 6. In manufacture, the band 1 is transversely arched in a direction opposite to the transverse curvature of the rim base, and then positioned in the recess 4 in an appropriate length of the extrusion. The curvature of the band is then reversed to seat it in the recess and the assembly then bent into a circle and the abutting ends of the extrusion welded together. The thickness of the band 1 may equal the depth of the recess 4 to provide a smooth transition at the edges 5, 6. Alternatively, the band thickness may be less than the recess depth, Fig. 5, so that after assembly of the band 1 in the recess, the recess edges 6 may be pressed down on to the band, Fig. 6.

Filed: 1975-10-09
Abstract: 1502124 Valves AIR PRODUCTS & CHEMICALS Inc 9 Oct 1975 41513/75 Heading F2V A valve seat 65 for a pressure regulator has two brass discs 100, 104, which between them hold a fluorocarbon seating member 110 with a tapered end, and a fluorocarbon seal 108 which seals the seat in the valve body. The valve member is moved relative the seat by a diaphragm 32 that is loaded by a spring 48, the end of which abuts a nut 46 to adjust the loading when the knob 15 and screw 38 is rotated. A porous filter surrounds the closure member and is held by a cap 56 sealed to the body by a fluorocarbon seal 25. A pressure relief valve 31 vents excess pressure from the low-pressure side and has a neoprene seal 90 which is fused on excess temperature to directly vent the low pressure side via closure member passage 88.

The hydrocarbon has a specific gravity at 25 DEG  C. of 1.1 to 1.7 and a boiling-point between 20 DEG  and 120 DEG  C. and is suitably methylene chloride, chloroform, carbon tetrachloride, 1,1,2-trichloro1,2,2 -trifluoroethane or a mixture of two or more thereof.
Patent GB-1011050-A (GB)
Title: Preparation of water soluble synthetic resins
Inventor: MARTIN JOHN CHARLES
IPC: C08G63/48
Filed: 1963-10-23
Abstract: A water soluble synthetic resin is formed by modifying an alkyd resin containing double bonds with a vinyl monomer and an alpha-beta unsaturated acid in the presence of a catalyst, the alpha-beta unsaturated acid being present in sufficient quantity to ensure that the acid number of the resultant resin is greater than 40, the hydroxyl equivalent of the resultant resin being from 100 to 200, and then solubilizing the resultant resin with ammonia or an organic water soluble base.  The unmodified alkyd resin may be prepared from a fatty oil, a polyvalent alcohol and an anhydride of a dibasic acid. In the examples the vinyl monomer is styrene, the alpha-beta unsaturated acid is methacrylic acid and the organic water soluble base is triethylamine or dimethylamino-ethanol. A stoving enamel is prepared from the resin solution of the invention and carbon black. Specification 665,195 is referred to.

Title: Photographic camera
IPC: G03B7/16
Filed: 1962-11-05
Abstract: 984,435. Photographic cameras; diaphragms. AGFA A.G. Nov. 5, 1962 [Nov.17, 1961], No. 41832/62. Addition to 984, 434. Headings G2A and G2J. In a camera as in the parent Specification having a diaphragm comprising two coaxial resiliently coupled rotatable diaphragm leaf bearing rings 6, 7 rotatable relatively against the loading of the resilient coupling such as spring 17, and wherein the rings are further coupled by a mechanism such as linkage 19, 20, the arrangement being such that by rotation of one of the rings-6 as shown-the two rings can be rotated together from a region in which the said mechanism is idle to a region in which it is responsive to the position of a control means to cause relative rotation of the rings to adjust the diaphragm, the control means is a focusing distance setting ring 30 having a control slot 50a, 50b co-operating with a pin, as pin 40, of the mechanism coupling the rings. As in the prior case, the diaphragm ring 6 can be manually adjusted along a scale 27 having separate ranges for flashlight exposures (27a), automatic exposure control (27b), and bulb exposures 27c. When the index 26 on the ring 6 is in the ranges 27b, 27c, the control slot 50a prevents relative movement of the linkage arms 19, 20 although relative movement of rings 6, 7 is possible due to movement of the linkage pin 15 in the concentric slot 51 in the lug 52 carried by the disc 7. When the index 26 is set on the flashlight range 27a in accordance with the appropriate flash number and held there by the spring 29 engaging in one of the notches 28, pin 40 rides in slot 50b and adjustment of the focusing scale 30 then adjusts the diaphragm aperture through radial movement of the pin 40 and hence rotation of the ring 7. In a modification, (Fig. 3, not shown), the two rings are connected by a single arm 19 pivoted on the ring 6 and bearing a pin 40. which due to the spring 17 bears against an edge of the lug 52 on the ring 7 when the index 26 on the ring 6 is set to the flash exposure range 27a.

The coating may contain 0À1-0À5 parts per 9 parts of SiO 2  of a resinous binder e.g. a polyvinyl chloride, a polyacrylate or a polyvinylidene chloride, and may also contain a surface active agent e.g. saponin. The imaged receiving sheet, which may be used as a lithographic printing plate, may be wiped before inking, with a conditioner, comprising carboxymethylhydroxyethyl cellulose, NaNO 3 , ammonium phosphate, glycerine, ethyl alcohol and cetylpyridinium bromide.

Title: Improved process and device for the pneumatic spinning of a yarn
IPC: D01H4/02
Filed: 1958-12-29
Abstract: 880,239. Spinning yarns. GOTZFRIED, K. Dec. 29, 1958 [Dec. 30, 1957], No. 41933/58. Class 120(2) Yarns are spun pneumatically by drawing a strand of fibres through a stream of air that is first caused to rotate and then to move in a helical path opposite to the fibre direction. Compressed air following the helical path is combined with a suction air current. Fibres are drawn by a roller 13 through a condenser 12 and passed to a plucking roller 15 that presents fibres or small fibre bunches to a suction nozzle 18 through which they are drawn to a conical spinning zone 1 within a suction pipe 29 and where they are twisted into a strand 20 by the influence of a downwardly and helically moving air stream from a compressed air chamber 9. The air stream initially circles around a twist chamber 4 and then descends in a helical manner losing pressure on the way by the escape of some air to an area confined by a suction sleeve 7. A tubular slide valve 26 may be employed to adjust the air flow. Fibres may be fed to an air tube by drawing apparatus. For fine yarns the lower part of the air tube may be set at an angle to the upper part. Reference has been directed by the Comptroller to Specification 825,776.

Abstract: 1,067,030. Air cushion vehicles. WESTLAND AIRCRAFT Ltd. Oct. 5, 1965 [Oct. 28, 1964], No. 44006/64. Heading B7K. To stabilize an air cushion vehicle when the leading part of the skirt becomes immersed in water, the external surface of the skirt (25) (Fig. 2, not shown) is formed with waterdeflecting strakes (25), the forward part of the skirt having transverse deflecting strips or projections (70). Further, spaced-apart, projections (46) (Fig. 3, not shown) may be positioned along the sides of the skirt and a buoyant member (71) (Fig. 19, not shown) may extend along the lower edge of the skirt. All the members may be hollow and inflated by air from the cavity formed in an inflated, doublewall skirt. The members (71) may be filled with foamed material. In a further embodiment (Figs. 3, 4, not shown) air-blowing nozzles (51) are positioned between water deflecting strakes (41) to reduce spray and to reduce the suction effect when the skirt becomes immersed in water. In a still further embodiment, (Figs. 15-17, not shown), the outer wall of the skirt is formed as two panels (63), (64) secured together by a porous strip (65) to provide a longitudinal gap (69) and secured to the inner wall of the skirt by chains (66), (67). In normal use the contiguous edges of panels (63), (64) will be pressed together by the air pressure within the skirt, thereby reducing air losses, but upon impact with a wave panel (64) will move or pivot upwardly to allow air to discharge through gap (69).
