Title: Improvements in or relating to variable-speed gearing
IPC: F16H61/662
Filed: 1957-04-24
Abstract: 859,569. Variable-speed gearing. BEIER INFINITELY VARIABLE GEAR CO. Ltd. April 24, 1957, No. 13113/57. Class 80 (2). A steplessly variable planetary friction gear comprises friction sun discs 9 connected for rotation with an output shaft 26 and in interpenetrating frictional engagement at their rims 10 with coned planet discs 7 on spindles 8 pivotally carried for radial movement by an input shaft 22 and in continuous toothed engagement through stepped planets 38 with a ring gear 17 prevented from reverse rotation, the friction planet spindles 8 being automatically adjusted radially to vary the speed ratio by input-carried centrifugal masses 1. The latter eventually clutch the ring gear frictionally to input for one-to-one drive. Zero output speed is within the range of adjustment and if an additional brake is provided to hold the ring gear 17 in both directions the adjustment may include reverse. The friction planet spindles 8 are carried on counterweighted bellcranks 6, Fig. 4, which, to adjust the planets 7 radially, are pivoted about the spindles 15 of the stepped planets 38, on which planets 37 on the friction spindles 8 roll in continuous toothed engagement. The pivotal movement is effected by the centrifugal masses 1 which, as they move outwards in radial guides in the input member 22, in opposition to return springs 2, cause pins 20 which they carry to move in cam slots 4 in a freely rotatable member 3, radial slots 12 in which act pins 13 on the bell-cranks 6 to turn them about the spindles to increase the penetration of the friction planets 7 into the sun 9 and hence increase output speed. The one-way brake on the ring gear 17 is a contracting coil spring. The sun discs 9 slide on axial pins 28 on freely-mounted pressure plates 27, 29, the latter connected to output 26 through an inclined toothed coupling 33 which increases axial pressure with torque increase, an initial loading spring 36 being also provided. Specification 859,570 is referred to. Reference has been directed by the Comptroller to Specification 781,396.

Title: Coating Process Involving Radiation Curing of Coating
IPC: C09D167/06
Filed: 1967-03-23
Abstract: 1,191,011. Coating. FORD MOTOR CO. Ltd. 23 March, 1967 [1 July, 19661, No. 13715/ 67. Heading B2K. [Also in Division B5] An object is coated by applying a liquid layer of a coating material which is capable of polymerisation by exposure to radiation, to the surface of a flexible pellicle, applying the coated surface to the surface of the object, and irradiating the combination of the object, the coating material and the pellicle by exposure to radiation of sufficient intensity to polymerise the coating material. Examples of suitable liquids are solutions of unsaturated polyesters in vinyl monomers e.g. polyesters formed from polyhydric alcohols such as ethylene glycol, propylene glycol, glycerol and unsaturated acids such as maleic, fumaric acids. Polybutadiene, polyisoprene can be used instead of the polyester. The vinyl monomer may be styrene, divinyl benzene. The coating may be irradiated using energised electrons having an average potential of 150,000 volts to 450,000 volts. The distance between the electron source and the coating may vary between 2 to 18 inches so as to achieve the minimum variation in polymerisation rates with depth. Objects mentioned are formed of heat sensitive materials e.g. plastics, rubber, glass. The pellicle may be metal or an inert organic substance so that the pellicle may be readily stripped away. The coated object can be left with the protective pellicle in place. The surface of the pellicle may be textured and such texture is then mirrored in the finished coating when the pellicle is stripped away. The pellicle may be given a prior coating which will be transferred to the finished coating e.g. if waxed paper is employed at least a portion of the wax may be transferred to the cured coating. The pellicle may be perforated to provide contrasting areas on the coated object. A portion of the coating material may be carried upon the protective pellicle and a portion applied to the surface to be coated before contacting the coated pellicle to such surface. Suitable materials for the pellicles are polyethylene terephthalate, aluminium, foil, waxed paper and glassine paper.
