Title: Process and device for the direct production of rubber sheets rubber-coated fabrics and threads and moulded articles from latex
IPC: C25D1/18
Filed: 1923-11-01
Abstract: 223,189. Anode Rubber Co., Ltd., (Assignees of Klein, P.). Oct. 11, 1923, [Covention date]. Moulding india-rubber. - Homogeneous deposits of india-rubber are obtained from latex by electrophoretic precipitation upon a permeable non-conducting surface or mould surrounding the anode, whereby the gases evolved at the anode can escape without interfering with the rubber deposit. The latex may be previously purified or concentrated, and preservatives, organic dyes, and sulphur may be added to it. The anode, which may be of metal or carbon, is either embedded m the permeable substance, consisting preferably of gypsum or unglazed earthenware, or is separated from it by a body of latex or other electrolyte. In the manufacture of shaped articles the anode and cathode may be moved relatively to one another to obtain a deposit of even thickness, or the cathodes may be so placed or to give a thicker deposit on any desired part of the mould. Fig. 2 shows an apparatus in which part of the mould b is protected by an insulating covering t so that no deposition occurs. In this modification the latex receptacle itself constitutes the cathode k. Fig. 3 shows an apparatus for the manufacture of sheets, comprising a revolving drum b, for example of gypsum, surrounding the anode a. The deposited sheet m is detached continuously from the upper part of the drum. In another modification an endless band of material to which the rubber does not adhere, e.g. fabric coated with cellulose acetate, passes over the drum and receives the deposit, which is continuously removed from its upper part.

Patent GB-762819-A (GB)
Title: A process for preparing siloxanes
IPC: C08G77/00
Filed: 1954-09-23
Abstract: Organopolysiloxanes of controlled viscosity are made by contacting one or more siloxanes of the formula <FORM:0762819/IV(a)/1> where R is a monovalent hydrocarbon or halogenated hydrocarbon radical and n has an average value of 1.98 to 2, with an aqueous solution of a monobasic acid having a dissociation constant of at least 0.01 at 25 DEG  C. and in amount of at least 10 per cent by volume of the siloxane, in a closed system at a temperature below that at which the organic groups are cleaved from the silicon until the viscosity of the siloxane has become constant.  Adequate mixing of the two phases may be effected by rapid agitation or by using an emulsifying agent. The reaction is effected preferably at 20 DEG  to 100 DEG  C. at any pressure and in the absence or presence of small amounts of water-immiscible solvents, e.g. toluene, ether and chloroform.  After the siloxane has reached equilibrium the acid layer is removed and the resulting product is a polymer having terminal acid groups, which on washing with water until neutral yields a hydroxyl-terminated polymer.  The average molecular size of the siloxane at the point of equilibrium depends upon the acid concentration in the aqueous phase, the higher the concentration the lower the molecular weight and vice versa.  The starting siloxanes, containing e.g. methyl, ethyl, octadecyl, vinyl, allyl, hexenyl, cyclohexyl, cyclohexenyl, cyclopentyl, phenyl, tolyl, naphthyl, xenyl, benzyl, chlorophenyl, bromoxenyl, pentafluoroethyl, chlorotrifluorocyclobutyl or trifluorotolyl radicals, may be liquid low molecular weight or non-flowing high molecular weight polymers, or the siloxane and acid may be formed in situ by simply adding an acidic silane, e.g. a dihydrocarbonyl dichloro-, dibromo- or bistrifluoroacetoxy-silane, and water to the reaction zone.  Acids specified are iodic, perchloric, nitric, benzenesulphonic, trichloracetic, trifluoracetic, periodic, hydrochloric, hydrobromic and hydriodic.  The products are useful in adhesives, for rendering fabrics water-repellent and proof against spotting by grease and as anti-foaming compositions. Examples are given.

Title: Improvements in gearing
IPC: F16H55/10
Filed: 1922-10-11
Abstract: 187,226. Bardet, J. Oct. 11, 1921, [Convention date]. No Patent granted (Sealing fee not paid). Toothed gearing; racks; toothed wheels.- Relates to a form of toothed gearing applicable to external, internal, and rack-and-pinion gearing in which practically pure rolling action is attained and consists in a pair of toothed elements in which straight-flanked. teeth pass side-by-side and engage one another, not directly, but through the intermediary of cylindrical pins lightly fitting the tooth-gaps and provided at their ends with loose rollers constrained to run in fixed cam grooves of such for as to produce constancy of gear ratio. As shown in Fig. 2, a pinion 1 has duplicate sets of parallel-sided teeth between which run similar teeth on a wheel 2. Hardened and ground pins 3 are carried round by the pinion 1, their rollers 4 running in a pair of stationary cam grooves 5. The centre-line of each groove 5 comprises an are p q, Fig. 3, concentric with the centre O<1> of the pinion and joined by tangent arcs p n, q m, to the useful portion m n of the locus k m n e, of the intersection of radii vectores R<1>, R<2> rotating uniformly about the centres O<1>, O<2> of the pinion and wheel respectively with velocities proportional to those of the associated wheels. In gearing of the usual proportions, a circular arc struck from some centre o<1> is a sufficiently close approximation to the curve m n, so that the whole groove can be easily machined. In internal gearing of 2.1 ratio, the cam groove is truly concentric with the pinion; in gearing of 1.1 ratio, the operative portion of the groove is straight. The shafts may be slightly displaced, as occurs in rolling-mill gears, particularly if the cam groove is so moved that its centre-line cuts the line of centres of the wheels in invariable ratio. Fig. 5 shows a modification, in which the teeth of the wheel 2 are spaced to embrace pins 3, which transmit drive from this wheel when it rotates in the sense of the arrow, auxiliary teeth 12 on the wheel 1, and pins 11, which drive in reverse and may have a diameter d<1> differing from the diameter d of the pins 3.
