Title: Improvements relating to the manufacture of stable preparations from rubber latex
Inventor: KERSHAW ARTHUR
IPC: C08K5/5415
Filed: 1948-02-13
Abstract: Natural or synthetic rubber latex is modified by reacting on the rubber particles with products from the hydrolysis in situ of an organo silicon ester in the presence of a protective colloid. The preferred colloid is neutralized caustic lignin such as the black liquid from paper manufacture neutralized with sulphuric acid, though casein, glue, alginates, pectins, dextrins, saponin, sulphonated fatty alcohols, or sulphonated oils such as sodium alkyl sulphates may be used.  A halogen such as iodine may be added with the colloid. In examples, a natural or concentrated latex is dispersed with an aqueous solution of neutralized lignin and an emulsion of ethyl silicate emulsified with triethanolamine or sodium alkyl naphthalene sulphonate and the resulting mix is then used to treat textile fabrics, wood flour, asbestos, whiting, china clay, or cement, or is precipitated with alum or lime and the supernatant liquid removed, and the residual paste concentrated, e.g. by spray drying.

Abstract: 482,776. Ironing - presses. JOHNSON, G. W., and HANNEY, A. F. Feb. 13, 1937, No. 4394. [Class 138 (ii)] In an ironing-press in which the head 18 is lowered into safe-closed positions by a piston- and-cylinder mechanism 24, 25 energized by the two manuals 31, 43, the operation of the manuals simultaneously admits fluid pressure above another piston 16 secured by a rod 17 to the buck 10 which is yieldingly mounted on springs 14. The buck is thereupon caused to descend, being guided over a stationary support 13 and compressing the springs in its descent. The toggle links 21, 22 are moved past straightline position by the piston 25 to a degree limited by stops 26, 27 and the manuals are then released. This causes the chamber 15 to exhaust through valve 40 and the buck rises rapidly, under the force of the expanding stressed springs, into final pressure engagement with the head which it holds locked. The cylinder 24 also exhausts itself on release of the manuals. The press is opened by operation of the manual 43 only which causes the piston 16 again to descend thereby permitting the spring 28 to break the toggle.
