Title: Improvements in devices for transmission by inertia
IPC: F16H33/08
Filed: 1922-10-06
Abstract: 189,099. Barbarou, M. J. B. Nov. 14, 1921, [Convention date]. Variable-speed gearing.-Automatically variable gearing comprises one or more mass members actuated from a driving-shaft and brought into engagement periodically with a driven member to which momentum is imparted. In the form shown in Fig. 4, the driving-shaft 1 carries a flywheel 22, a friction clutch surface 23, and camactuating bowls 28. The driven member has a clutch surface 26 and is normally thrust to the left by a spring 32, so that a cam face 29 is thrust against the bowls 28. The mass member is a double clutch ring 25 which can move conically being thrust towards the right by a spring 31. When the driven shaft 14 turns at a different speed to the shaft 1, the driven member 26 keeps vibrating axially, so that the mass member 25 is alternately allowed to engage the member 23 and absorb momentum and carried away by the member 26 to which it imparts momentum. In a form shown in Fig. 7, a driving fly-wheel 42 carries spindles 43<a> carried in pivoted bearings 44. Each spindle 43<a> has at one end a mass member or disc 43 and at the other a friction cone 45. Relative motion between driving-shaft 1 and driven shaft 14, through cam gearing 48, 49 and a spring 41, causes a central cone 46 to vibrate axially. Then the cone 46 recedes, the discs 43 fall outwards against a flange 42<a> on the wheel 42 and pick up momentum. When the cone advances, it takes up momentum through the cones 45, the discs 43 being withdrawn from the flange 42<a>. In another form, planetary mass members carried by a driving-drum alternately engage cam swells on a driven internal drum so as to drive it, and are left free, so as to be actuated by the driving-drum alone. In a form shown in Fig. 8, the driving- shaft 1 carries the through axle 1<a> of an epicyclic train, which drives two loose fly-wheels 54, 54a. The driven member is a spider 55 which carries brakes 60, 60<a>. The brakes 60, 60<a> are applied alternately to the fly-wheels by cam mechanism 56.

Title: Improvements in or relating to machines for capping bottles
IPC: B67B3/12
Filed: 1924-11-13
Abstract: 231,777. Page, S. E., (Soc. Anon. de Construction de MatÚriel d'Alimentation et de Bouchage Metallique). Nov. 13, 1924. " Crown corks " and the like, applying.-A bottle capping machine comprises a frame 2 carrying a reservoir 1 for gas under pressure, a plug 8 at the bottom of the reservoir, 'an outer or clinching piston 10 slidable in the plug 8 and supporting the usual capping mechanism, an inner or compression piston 13 slidable in the clinching piston 10, and a spring- pressed plunger 14 mounted in the compression piston 13. A small quantity of oil above the pistons maintains an hermetic seal between them and the wall of the reservoir 1. In operation a cap, such as a " crown cork " 26, is placed on a support 25 on a guide nut 12 mounted on a neckcarrying support 11 on the clinching piston 10. The bottle 27 is raised, or the capping head is lowered so that the cap is pressed betwen the plunger 14 and the bottle mouth, continued movement raising the plunger until a ring 24 mounted on it abuts against and raises the compression piston 13 thereby substituting its pressure for that of the spring 16 of the plunger 14 and pressing the cap on to the bottle mouth. The pressure on the cap increases as the movement continues until the cap, pressing against a throat 23 in the member 11, is crimped around the bottle neck, when further movement merely raises the clinching piston 10.

Abstract: 1,193,830. Chlorination process. HALCON INTERNATIONAL Inc. 13 June, 1967 [17 June, 1966], No. 27181/67. Heading C2C. Perchlorinated C 1-4  hydrocarbons, e.g. carbon tetrachloride and perchloroethylene, are obtained by the exhaustive thermal chlorination of C 2-4  hydrocarbons or partially chlorinated hydrocarbons using excess chlorine, the unreacted chlorine from the product mixture being recovered by reacting it with C 2-4  unsaturated hydrocarbons to produce partially chlorinated hydrocarbons, e.g. 1,2-dichloroethane, provided that when the C 2-4  hydrocarbon or partially chlorinated hydrocarbon is other than ethylene, a chloroethylene or the product of the partial chlorination of ethylene, the chlorine recovery is effected without prior separation of the perchlorinated hydrocarbon product. The product of the exhaustive chlorination may be quenched, e.g. by contacting it with a circulating stream of carbon tetrachloride and/or perchloroethylene, and then passed directly to a partial chlorination reactor or, if appropriate a portion of the quenched product may be passed to a scrubber where it is contacted with refrigerated perchloroethylene to remove substantially all the chlorinated hydrocarbon before passing the gaseous effluent containing chlorine and hydrogen chloride to the partial chlorination reactor, and remainder of the quenched product being recovered directly. The partially chlorinated hydrocarbons produced may be recycled to the exhaustive chlorination reactor optionally together with the perchlorinated hydrocarbon product or, in the case of 1,2-dichloroethane, some of it may be recovered, purified and used for the production of vinyl chloride.
