Title: Improvements in or relating to the tanning of leather
IPC: C14C3/02
Filed: 1942-11-24
Abstract: 569,909. Tanning. NATIONAL OIL PRODUCTS CO. Nov. 24, 1942, No. 16626. Convention date, Nov. 21, 1941. [Class 76] [Also in Group III] Tanning agents are prepared by treating sulphonated aromatic compounds with from 1/16- “, preferably not more than # molecular proportions of a hexavalent chromium compound in aqueous solution. The sulphonated compounds which can be used are sulphonated cresols. phenols, other hydroxy aromatics such as # naphthol or gallic acid, sulphonated alkyl aromatics such as diamyl naphthalene, amyl phenol or lauryl benzene, sulphonated aromatic aldehydes or ketones such as benzaldehyde or 4, 4<1>- diliydroxy benzophenone and sulphonated condensation products of any of these aromatic compounds with formaldehyde. Sodium or potassium dichronate is the preferred chromium compound. Negatively charged complex chromium ions are formed. The products are used for tanning leather, especially pretanning heavy leather prior to vegetable tanning. Condensation products of the sulphonated aromatic may be effected with up to 3, preferably ¢ molecular proportions of formaldehyde, using low temperature to prevent resin formation. The dichromate, preferably as a 50 per cent. aqueous sulphuric acid solution may be added to the sulphonated compound at about 10-15‹ C., the temperature rising later to that of the room. Alkali such as 15-30 per cent. caustic soda is added to neutralize excess acid so that a 2 per cent. solution of the product has a pH of about 3 to 6. In example: (1) cresylic acid is heated with sulphuric acid and formalin added at below 25‹C. Sodium dichromate solution is added at below 10‹ C., rising to room temperature, and the product neutralized with caustic soda; (2) and (3) sulphonated phenol is similarly condensed with ¢ or molar proportion of formaldehyde and then reacted with 1/16 molar proportion of dichromate. Specifications 16647/86, 146,167, and 155,887, [all in Class 76], are referred to.

Filed: 1955-06-10
Abstract: 791,137. Traverse mechanisms. T.M.M. (RESEARCH), Ltd. June 1, 1956 [June 10, 1955], No. 16817/55. Class 120(2) [Also in Group XXIV] In a cam-operated traverse mechanism for a textile twisting machine a carriage 16 actuating the thread guides and carrying a follower 20 is reciprocated by a rotating cam 19 which is periodically accelerated and decelerated by means of an auxiliary cam or swash-plate 26. The cam 19 is freely rotatably on a stationary shaft 21, and is coupled to a coaxial driving gear 22, also loose on shaft 21, by means of a T-shaped member 28 on the cam 19 engaging a groove in the swash-plate 26 which is carried in brackets 23 on the gear 22 so as to be bodily rotated thereby about the shaft 21. The swash-plate is also rotatable on its own axis together with a worm wheel 25 engaging a worm 27 fixed on the stationary shaft 21. As the swash-plate 26 is bodily rotated to drive the cam 19 it is thus simultaneously slowly rotated about its own axis so that the cam 19, and consequently the carriage 16, receive a periodic acceleration and deceleration at each revolution of the swash-plate about its own axis. The carriage 16 slides on rails 17 and is attached to a rod 15 carrying guides 14, Fig. 3, for threads being wound on spools 10 frictionally driven by rollers 11. The periodic acceleration and deceleration of the reciprocating rod 15 causes succeeding layers of the threads to be wound at varying helix angles. It is stated that in a modification the working parts may be housed within the cam to achieve compactness.
