Filed: 1921-03-08
Abstract: 179,730. Stanhope, H. March 8, 1921. Deflectable axle-ends; controlling different functions by same handle.-A driving and steering wheel is spring mounted on and pivoted to an L-shaped casting which can slide on longitudinal frame members, the wheel being driven through tcothed gearing from a universally jointed shaft driven by belt and expanding pulley gearing; the movement of the casting along the frame members effects the tensioning of the belt and is controlled from the same lever as the expanding pulley. The wheel 16 is mounted on a short axle 15 mounted in a member 4 which is provided with ears riding between springs mounted on vertical rods mounted on a bearing plate 20, the member 4 being pivoted in the casting 1. The casting 1 is provided with holes 5, 6 by means of which it is adjustably supported on longitudinal frame members. The wheel is driven by a shaft 9 and toothed gearing 17, 18, the shaft 9 being driven by a double pulley 7 mounted on a bearing 2. The casting is moved longitudinally by a rod 34 operated by a hand-controlled screw 36 and the rod is connected by a lever 49 and links 47, 48 to levers 43, 44 operating the expanding pulleys 39.

Abstract: 392,324. Photographic plates. KODAK, Ltd., Kingsway, London.- (Staud, C. J. ; Kodak Park, Rochester, New York, and Webber, C. S. ; 271, Norfolk Street, Springfield, Massachusetts, both in U.S.A.) March 11, 1932, No. 7379. [Class 98 (ii).] A silver halide emulsion layer is hypersensitized by means of an ammonia compound containing at least one alkyl group and at least one hydroxyl group. These compounds also render the emulsion layer and/or the support more plastic, and also improve the keeping properties of the latter. The ammonia compound, e.g. mono-, di-, or tri-ethanolamine, #-alkylhydroxylamines, #-diethylaminoethylalcohol, #-diethylaminopropylalcohol, and diethylaminopropylalcohol, may be added to the support or the emulsion, or the emulsion layer may be bathed with a solution of the compound. In examples : (1) acetone soluble cellulose acetate is dissolved in a mixture of triethanolamine and acetone and a film formed therefrom ; (2) a 0-2 to 0-5 per cent aqueous solution of the ammonia compound, a little ethyl alcohol being added if necessary to obtain a clear solution, is used for hypersensitizing a panchromatic film ; (3) the hypersensitizer is added to the emulsion at any stage in its manufacture, in amount of the order of 0-5 per cent by weight of the emulsion.

Abstract: 959,059. Moulding rubber mats. GOODYEAR TIRE & RUBBER CO. Feb. 28, 1962, No. 7775/62. Heading B5A. A mat is made by vacuum moulding a rubber blank and then vulcanizing the blank by applying heat through the moulding face. The mould base 1 has an insert 3 with the desired surface configuration and is bounded by a strip 4 which has a groove 5 and air bleeds 6 connected to a vacuum chamber 7, this arrangement serving to conform the rubber blank 12 to the mould shape. The rubber is then vulcanized by a source of heat, e.g. electric element, steam pipes, in the mould base 1, the process being facilitated by an insulating blanket or hood over the blank. The steam pipes may be embedded in a good conductor below the mould base with a layer of insulating material below. When the insert 3 is exposed its temperature is below the necessary vulcanization temperature, but when the blank and insulating blanket are applied its temperature rises to a suitable vulcanization temperature. The whole apparatus may be mounted on a sloping frame.
