Patent GB-176662-A (GB)
Title: Improvements in or relating to variable speed gear
IPC: F16H29/08
Filed: 1921-03-04
Abstract: 176,662. Lees, A., and Lees, H. March 4, 1921. Variable-speed ratchet gearing is of the type shown in Fig. 1, links G, H transmitting power to friction ratchets G<3>, H<3> having an adjustable connection with a lever D, which is oscillated by a driving-crank B. The invention resides in the use of a revoluble cam O, Figs. 2, 4, and 5, for reversing the friction ratchets. As shown in Fig. 2, the ratchets G<3>, H<3> are in the form of double-ended eccentrics which are tilted by the cam O so as to bring one end or the other of the ratchet into action alternatively. As shown in Fig. 4, the ratchets comprise a pair of coupled eccentrics 17, which are brought into action alternatively. In one arrangement shown in Fig. 5, balls G<3> coupled by a head 19 and links are brought into action alternatively by the cam O so as to drive in opposite directions. Specifications 14678/99 and 25956/01 are referred to in the Provisional Specification.

Title: Improvements in electromagnetic couplings
IPC: H02K49/04
Filed: 1960-03-01
Abstract: 919,441. Positive clutches; change-speed gear. EATON MANUFACTURING CO. March 1, 1960 [June 11, 1959], No. 7164/60. Class 80 (2). [Also in Group XXXV] A motor vehicle gear-box receives drive through one or other of two electromagnetic powder clutches (see Group XXXV) from the engine flywheel, one clutch providing a direct drive through shaft 85, and the other driving through hollow shaft 43 into the gear-box at pinion 45 engaging countershaft gear 163. The second-speed gear 197 rotates on the main shaft 85 by means of needle bearings 199 and carries crown teeth 201 which may be engaged by the internal splined teeth 203 of a synchromesh ring 205 splined to hub 209 fixed to the main shaft. This hub has slots 213 which accommodate detent plates 215 biased outwardly by annular springs 217. Each of these plates has its right-hand end located with some freedom in an axial notch 223 in a blocker ring 225. When ring 205 is shifted to the right it drives plates and blocker rings to the right so that conical surfaces 229, 231 engage to synchronize the gear 197. The loose fit of plates 215 in notches 223 allows the blocker ring to turn into a semi-blocking position of its teeth 227 with the teeth 203 until synchronization. Further movement to engage the teeth 201 releases the indexing dimples 219. To engage the lowspeed drive, gear 179 is moved to the left to engage its internal splined teeth 181 with teeth 185, the drive being then through gears 169 and 193, an overrunning clutch 195, and a sleeve 187 which is normally free on the main shaft. To engage reverse gear, gear 179 is shifted to the right to mesh with idler gear 177.

Filed: 1964-02-20
Abstract: A stable latex of a copolymer of at least one a -olefin with at least one non-conjugated diene hydrocarbon is prepared by mixing with high-shear agitation at a temperature between 15 DEG  and 75 DEG  C. a solution of the copolymer in an inert organic solvent with water in the presence of an emulsifying agent in amount sufficient to allow the formation of a stable oil in water emulsion, and removing the solvent from the mixture, e.g. by stripping.  Many a -olefins and non-conjugated dienes are listed.  Copolymers exemplified are ethylene/1, 4-hexadiene, ethylene/propylene/1,4-hexadiene, and ethylene/propylene/dicyclopentadiene. Suitable solvents include trichloroethylene, carbon tetrachloride, and n-hexane.  The solvent is either mixed directly with the copolymer or mixed with a composition comprising the copolymer and additives such as oil extenders, fillers, and antioxidants.  One exemplified composition comprises a copolymer with bentonite clay, a terpene resin, a naphthenic petroleum oil, and oleic acid.  The emulsifying agents are preferably non-ionic or anionic, and emulsification modifiers such as ammonium caseinate or sodium alginate may be included.  In one example a polychloroprene latex is added to the formed copolymer latex.  The copolymer of ethylene/propylene/1,4-hexadiene is prepared by polymerizing the monomers using a VOCl3/diisobutyl aluminium chloride catalyst.ALSO:Specially prepared stable cationic latices of copolymers (see Division C3) may be incorporated into Portland cement to improve, for example, its power of adhesion.ALSO:A specially prepared stable latex of a copolymer of at least one a -olefin and at least one non-conjugated diene hydrocarbon is used to impregnate paper by immersion of the paper in the latex and then blotting, drying and curing the impregnated paper.  The latex is prepared by mixing with high-shear agitation at a temperature between 15 DEG  and 75 DEG C. a solution of the copolymer in an inert organic solvent with water in the presence of an emulsifying agent in an amount sufficient to allow the formation of a stable oil in water emulsion, and removing the water from the mixture e.g. by stripping.
