Abstract: 330,067. Royce, F. H. April 17, 1929. Variable-speed gearing.-Between a two-speed lay-shaft gear d, Fig. 1, and the engine clutch a<2> upon a vehicle is arranged a two-speed epicyclic train in which each setting of the clutch i and brake k, k<1> is spring-loaded. The driven shaft c of the epicyclic train preferably carries the planets c<5> which mesh with a driving internal ring b<1> and with a sun e which is clutched or braked alternatively. The clutch i connects an extension e<1> of the sun e to an extension b<4> of the ring b<1>. The clutch i is engaged by a spring h and disengaged by the angular displacement of a cam lever p<4>, Fig. 2, the companion cam lever p<3> being anchored at p<5>. Brake and clutch are operated by a lever m which is spring-loaded in both extreme positions by spring toggles n'. The brake shoes k, k<1> tend to be held in engagement with drum j<2> by a lever l acted on by a spring l<3>. In the position shown in Fig. 2, the brake shoes are held disengaged by a projection m<2> upon lever m engaging lever l. At the same time, cam lever p<4> holds clutch i in engagement for the high speed of the epicyclic train. On throwing toggle lever m over, the clutch is disengaged and the brake shoes are engaged by spring l<3>, bringing in the low speed. The throwing over of lever m is effected by a piston o' operated by engine suction.

Abstract: Hydrophilic swollen shaped articles such as contact lenses, plates or filling bodies for surgical purposes, pessaries or diaphragms, are made by cross-linking long-chain linear polymers containing numerous hydrophilic non-ionic groups in a mould which has the shape of the desired article or the shape of a block from which the article is shaped by cutting, the cross-linking being effected so as to obtain, on an average, one cross-link for every 50 to 600 monomeric units of the linear polymer, the process being carried out in the presence of water and/or a water-soluble inert liquid such as ethylene glycol, a poly-alkylene glycol or glycerine constituting 20 to 97% of the total weight of the reaction mixture, the article thereafter being washed with water and then stored in water or an aqueous solution.  The hydrophilic groups of the polymer may be hydroxyl, ether, amide, triazole, tetrazole or lactone groups.  In examples: (1) a solution of polyvinyl alcohol in water is heated with adipic acid and hydrogen chloride until a hydrogel is obtained; (2) polyvinyl alcohol is partially esterified with methacrylic anhydride and the resulting ester is polymerized in solution in water in the presence of a mixture of potassium persulphate and sodium thiosulphate; (3) triethyleneglycol monomethacrylate and dimethacrylate are copolymerized in a mixture of ethylene glycol and water in the presence of potassium persulphate.
