Title: A process for the production of film forming aqueous dispersions of copolymers of vinyl esters of organic acids
Inventor: RITCHIE DOUGLAS IAN
IPC: C08F218/04
Filed: 1966-06-10
Abstract: A film forming aqueous dispersion of a copolymer of a vinyl ester of an organic acid is prepared by copolymerizing a vinyl ester of a saturated monocarboxylic acid and octene-1 in aqueous dispersion in the presence of a free radical catalyst and a surface active agent and/or a protective colloid.

Title: Improvements in hoists or winches
IPC: B66D1/20
Filed: 1919-10-22
Abstract: 158,050. Prinsep, F. T. L. Oct. 22, 1919. Driving-gear and regulating and control-transmitting gear for winding and paying-out apparatus.-In winches of the type in which a loosely-mounted drum can be moved by an eccentric and hand-lever in opposite directions from a central free position in which a brake is applied automatically, thus connecting the drum to friction gearing for driving it in one direction or the other, special means are provided for operating the brake and moving the drum simultaneously. In the illustrated form, the drum e is mounted loosely on the eccentric shaft f<1> and can be moved into contact with friction wheels b<2>, d<2> for driving in opposite directions. Each friction wheel is connected to a corresponding spur-wheel, one of which is driven directly from the motor shaft a<1> and the other through an intermediate spur-wheel c. The invention consists in linking the hand-lever j, which is fitted with setting and retaining devices j<4>, to a lever h<1> which carries a toothed quadrant h or rack for engagement wth a similar quadrant or pinion to rotate the shaft f<1>, and during its rocking movement also rotates the shaft h<2>, thereby operating an eccentric h<3> to apply or release the brake k<1>. In a modified application, the mechanism is applied to a winch drum with internal and external friction driving surfaces. In such cases one of the pair of wheels b<2>, d<2> contacts with the internal, and the other with the external surface of the drum, while the intermediate wheel c is ornitted.
Patent GB-188868-A (GB)
Title: An improved method of transforming into sulphates, by the action of nitric acid, such metals and alloys as are insoluble or only gradually soluble in sulphuric acid
IPC: C01G1/10
Filed: 1921-09-30
Abstract: Metals or alloys not readily soluble in sulphuric acid are converted into sulphates by first dissolving in nitric acid, and then adding sulphuric acid to convert the nitrates into sulphates. During both stages air is blown into the solution to remove the nitrogen oxides and nitric acid, and nitric acid is recovered of sufficient strength for subsequent use.  The sulphate is separated by crystallization and the mother-liquor which contains nitric acid may be used again.  The process may be used for the treatment of copper nickel and brass. The production of copper-magnesium sulphate is also mentioned.

Abstract: 170,477. Gray, B. P. Sept. 15,1920. Hoof-pads; bar shoes.-In hoof-pads for horses and mules of the kind in which a resilient plate lying between the hoof and the shoe carries a pad between the sides of the shoe, and particularly cf the kind described in Specification 113,988, the pad is shaped at the sides to engage the inner sides of the shoe to prevent movement of the pad towards the heels of the shoe, and the plate is provided with flanged-over parts or projections abutting against the heel ends of the shoe to prevent movement of the pad towards the toe of the shoe. The pad. is thus held in place without being permanently fastened to the shoe, and may be removed from the shoe without removing the shoe from the hoof, the flanged-over parts or projections being in some forms removably secured to the shoe to facilitate the removal of the pad. In one form, shown in Fig. 2, the plate 4 carrying the pad 2 has rear extensions 7 the ends of which are bent up, either during manufacture of the plate 4 or during its application to the hoof, to form hooks 8 abutting against the heel ends 15 of the shoe 1. In a modification, shown in Fig. 5, members 11 of sheet metal or wire with 'bent ends 12 hooking over the heel ends 15 of the shoe are detachably secured to the plate 4 by the engagement of hook-shaped rear-ends of the members 11 either with holes 9 in the plate 4 or with the edge of the plate 4. In another modification, shown in Fig. 7, rear extensions 13 of the plate 4 receive detachable stops 14, such as bolts, abutting against the heel ends 15 of the shoe.
