IPC: F16C3/28
Filed: 1952-01-17
Abstract: 723,439. Eccentrics. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 17, 1953 [Jan. 17, 1952], No. 1378/52. Class 122 (1). A variable-throw eccentric com prises first means 25, 26, Fig. 3 which co-operate with second means 1, 2 in a driving shaft 4 for the sheave 24 of the eccentric such that upor relative movement between the first and second means the eccentricity of the sheave is varied. The first means comprise segmental racks 25, 26 secured by screws 29 within the bore of the sheave 24 which may be slightly eccentric. The racks 25, 26 have teeth 27 inclined to the axis of the shaft 4 at an angle less than the angle of friction between the material of the racks and that of the racks 1, 2 with which they mesh so as to be selflocking following sliding movement of the racks 1, 2 in the bore 3 of the shaft 4 to effect adjustment of the eccentricity of the sheave 24. A rod 12, Fig. 4, secured by screws or pins 12a to the semicircular rack 2, is received within the bore 10 of the semicircular rack 1, and a compression spring 19 acting between abutments 9, 15 tends to produce axial sliding between the racks 1, 2 and eliminates back-lash between them and the segmental racks 25, 26. A member 22, Fig. 2, through which adjusting movement is imparted to the racks 1, 2, may be advanced by a screw 23 that passes through a threaded bracket and is provided with stops to limit its movement. A bearing 21 at the end of the member 22 is slidable on the rod 12 and engages the end of the rack 1 or a stop collar 17 secured to the rod depending upon its direction of movement. This engagement compresses the spring 19 and releases the locking action between the teeth of the racks before changing the eccentricity of the.sheave 24 which may carry a bearing to transmit its eccentric motion. The extent of relative movement between the racks 1, 2, restricted by the stop collar 17 and a further collar 18 integral with or attached to the end of the rack 2, is less than that required to effect unlocking and then re-locking of the rack teeth in the same direction of relative movement between the racks 1, 2. The spring 19 may be arranged to act in tension.

Title: Improvements in or relating to the deposition of rubber on fibrous material
IPC: D06M15/693
Filed: 1942-02-05
Abstract: 554,572. Depositing rubber on fibrous material. McKAY, R. F. (United States Rubber Co.). Feb. 5, 1942, No. 1519. [Class 70] Rubber is deposited on fibrous materials from a bath containing a flocculent precipitate of rubber prepared by treating latex or other aqueous dispersion of natural or synthetic rubber containing compounding ingredients with a flocculating agent in presence of a stabilizing agent which prevents the flocs agglomerating. The latex may be compounded with vulcanizing agents, sulphur, zinc oxide, clay &c. and may be flocculated by salting out with monovalent metal or ammonium salts of strong acids, e.g. ammonium sulphate, in presence of a protein such as gelatine or by addition of polyvalent metal salts in presence of clay, or by precipitating a polyvalent metal silicate or silicic acid gel in the latex. The stabilizers may be those known for stabilizing latex, and particularly compounds containing the groups R-COOM, R-SO 3 -M, R-SO 2 -M, R-OM and RO-SO  3 M, where R represents an organic radical having a straight chain or ring structure which may contain substituents and M represents hydrogen, alkali metal or ammonium. Numerous examples are given of compounds of the general formula RSO  3 M, where R is an organic radical containing at least one group of more than 8 carbon atoms. The process is applicable to increase the snag resistance of silk stockings. If the deposition takes place from a non-acid bath, the fibrous material is treated with acid before drying to fix the agglomerates. Specifications 508,136 and 508,137 are referred to.
