Title: Automatic variable speed transmission
IPC: F16H33/12
Filed: 1957-09-30
Abstract: 849,684. Variable speed gear. BANCROFT, C. Sept. 30, 1957, No. 30571/57. Class 80 (2). A variable speed epicyclic gear is controlled automatically by a flywheel 21 which is caused to rotate with a cyclically varying speed by relative rotation between input and output shafts 1, 7. Forward rotation of the input 1 relative to the output 7 causes reverse rotation of an input-carried planet pinion 4, meshing an output ring gear 6, whereby a radially slotted guide 5 fast with the pinion 4 reciprocates over a crankpin 9 to impart cyclically varying rotation to a sleeve 10 carrying the pin 9. The accelerating impulses of the crank sleeve 10 are passed to the flywheel 21 by a bevel differential gear comprising planets carried by the sleeve 10 meshing a side wheel 15 integral with the flywheel 21 and a side wheel 14 carrying two one way devices, one 17 a detent, reacting on the fixed casing 19 to cause the flywheel to receive the acceleration impulses, whilst the other, 18, a clutch, acts oppositely, so that, when, during the decelerating impulses of the crank sleeve 10, the flywheel over-runs, the one-way clutch 18 transmits the over-run movement of the flywheel to an output mounter member 20. The output 7 is thus driven at a speed ratio which varies automatically with the load. To provide reverse the ring gear 6 may be held stationary and the output shaft 7 clutched to the casing 19. In Figs. 2 ... 4 (not shown) two flywheels are used to smooth the action of the transmission. The pinion on the input crankpin has two diametrically opposed guides in which slide two crankpins, each connected through a crank sleeve and a speed planetary gear to their respective flywheel. The suns of each gear are (Fig. 2, not shown) held against reverse rotation by one-way detents. Each flywheel is connected to the output through the planetary speed gear and a planetary bevel gear. To balance the stresses the input crankshaft is formed with a second crank of equal throw to the first but 180 degrees out of phase therewith, the crankpin of which carries a pinion with radial guides which are companion to the above mentioned guides and crankpins connected to their companion crankpins slide within the guides.

Abstract: 720,246. Electromagnetic relays. FRILLEY, M. Dec. 3, 1952 [Dec. 10, 1951], No. 30705/52. Class 38 (5) A high sensitivity electromagnetic relay 1 of the moving coil type comprises a movable contact 6 which is closed against a second contact 7 when continuous current of a predetermined strength flows in the coil 2, the contacts being caused to oscillate one with respect to another by passing alternating current through the coil or another coil movable therewith. The continuous current supply is represented at 10, the alternating current being supplied by a transformer 14 over a potentiometer 13, which alternating current may be cyclically interrupted by means of a cam 15 and contacts 17. The contacts 6, 7 are arranged so that the contact point between them varies according to the current strengths in the coil by disposing the contact point'between the contacts remote from a straight line joining the centres of rotation of these contacts (see Fig. 2b). This effect is further accentuated by inclining the contact surface of the contact 7.

Title: Improvements relating to styrene polymerization
IPC: C08F12/08
Filed: 1937-11-12
Abstract: 511,417. Vinyl polymerization products. DU PONT DE NEMOURS & CO., E. I. Nov. 12, 1937, No. 31102. Convention date, July 22. [Class 2 (iii)] Styrene, or a mixture of styrene with an ester of methacrylic acid, is polymerized in the presence of sulphur dioxide as a catalyst, by exposure to ultra-violet light at room temperature or at an elevated temperature, or by the use of heat at atmospheric or higher pressure. Specified esters are methyl, ethyl, propyl, butyl, amyl, catyl, cyclohexyl and bornyl methacrylates and ethylene glycol methacrylate. The polymer may be obtained in a granular or pulverulent form adapted for use as a moulding powder by carrying out the polymerization with the styrene or the mixture dissolved or dispersed in a liquid medium. The liquid medium may be (a) a non-solvent for both the monomer and polymer, e.g., water or a water-alcohol mixture in which the proportion of alcohol is below 50 per cent. (b) a solvent for the monomer but not for the polymer, e.g., aliphatic alcohols or a water-alcohol mixture in which the ,proportion of alcohol is above 50 per cent., or (c) a solvent for both monomer and polymer, e.g., aromatic hydrocarbons or cyclic ethers, e.g., dioxane. The styrene may be emulsified with the liquid medium, e.g., water, with the aid of an emulsifying agent such as dodecyl pyridinium chloride, dodecyl sodium sulphate, or'sodium oleate. When mediums (a) or (b) are employed, a coagulant such as a mineral acid may be, used to facilitate complete separation of the polymer from the suspension, and when a medium (c) is employed, recovery of the polymer from the solvent may. be effected by pouring the solution into a non-solvent liquid. Polymerization may also be effected by heating the monomer in a mould in the presence of dissolved sulphur dioxide. Plasticizers, fillers, dyes or pigments may be added before, during, or after polymerization. Dispersions of the polymers may be used directly as impregnating agents for paper, cloth &c. In examples, (1) styrene, or styrene and ,methyl methacrylate, sulphur dioxide and water are heated under reflux, and the polymer is allowed to settle, washed with alcohol and dried, (2) sulphur dioxide is passed through a heated solution of styrene in ethyl benzene, the reaction mixture is poured into alcohol, and the precipitated polymer is washed with hot alcohol, and (3) monomeric styrene containing dissolved sulphur dioxide is heated in a bottle.
