Abstract: 1,005,745. Tyre building apparatus. B. G. NORTON. Oct. 6, 1961, No. 36108/61. Heading B7C. Apparatus for depositing a layer of elastomeric material on a new or buffed type carcass comprises means for supporting the carcass and rotating it about its axis, a feeding head for applying to the carcass a ribbon of the elastomeric material of which the width is several times the thickness, and means for moving the feeding head transversely relative to the carcass to produce a winding of the ribbon which extends from one side to the other of the mid-circumferential plane of the carcass and of which successive turns overlap, means also being provided for manually varying the relative transverse movement per carcass revolution to cause the turns of the winding to overlap to a varying degree thereby varying the thickness of the layer. In one embodiment, as applied to tyre retreading, a buffed carcass is rotated at constant speed by a motor 20 (Fig. 2). Ribbon 56 and lining 54 (Fig. 3) are wound off from a reel 59 which is pivotable about an axis 42 (Fig. 2) by a motor 22 at a variable speed controlled by a manually-operated lever 92. The ribbon is stitched to the carcass by a wheel 50 (Fig. 3), held down against the carcass by a pneumatic ram 80 (Fig. 2), connected to arms 47, 47a. The ribbon may be heated by infrared rays or by heating the feed rollers, or the ribbon or carcass may be sprayed with cement, if the ribbon is not sufficiently tacky under ambient temperatures. In a modification (Fig. 8, not shown), the reel 59 is replaced by a continuous extruder. In a second embodiment, ribbon is wound round a green cylindrical carcass, to form both tread and sidewalls, in a variable pitch spiral by moving the stitching roll at a variable speed along a line parallel to the carcass axis. The speed of the motor 20 may be varied. The entire layer may be of conventional rubber or (see Fig. 22) conventional rubber may be applied as the feeding head follows the path 1904 and, along the path 1905, rubber having a uniform dispersion of e.g. wood chips, walnut shells, silica, or cork.

[Also in Division H1] A bore is formed in a watch jewel or other workpiece by locating the workpiece at the focus of a laser having an optical focusing system, and subjecting the workpiece to a train of pulses of wavelength exceeding 1 Á, each pulse having an energy content of between 0.1 and 0À8 joule and a duration of 100 Ás or less. The laser may comprise a rod of yttrium-aluminiumgarnet pumped by a flash tube, the output energy being focused by a lens 1, Fig. 1, on to a jewel workpiece 3 held in a chuck 2. Successive laser pulses may be of different energy, the first pulse being relatively weak. Formation of the bore may be assisted by progressively displacing the focus either in the direction of the bore or laterally. Removal of waste products may be effected by passing a gas stream from a nozzle 4 over the workpiece and also through a central duct in the chuck, the gas consisting of air, oxygen, nitrogen or hydrogen. The workpiece may alternatively be bored in a vacuum or in oxygen or an inert gas. A single gas stream applied through an inlet pipe 7 is used in Fig. 2, the gas being directed by a casing 5 through the bore in the jewel as soon as it is formed. A window 6 passes the laser energy. Electrostatic precipitation of particles ejected from the bore is used in Fig. 3 (not shown). In Fig. 4 (not shown) the lens system is protected by a glass screen over which a curtain of flowing liquid is applied, while the gas scavenging medium is applied to the rear of the workpiece. The gas scavenging medium may be applied continuously, pulsed, or alternating in direction and may include a fine abrasive. The workpiece may be preheated.

Abstract: 1,250,530. Synchronizing systems. WESTINGHOUSE ELECTRIC CORP. 30 Dec., 1968 [4 Jan., 1968], No. 61585/68. Heading H2H. Apparatus for synchronizing an A.C. generator on to an A.C. bus bar by way of a normally open circuit breaker having a finite closing time comprises means for generating a synchronizing signal to energize the circuit breaker in advance of synchronism of the generator and bus-bar parameters by a time equal to the closing time of the circuit breaker whereby the circuit breaker closes to connect the generator to the bus-bar at the instant of synchronism. The apparatus includes a number of transistor logic units such as a converter, synchronizer, voltage acceptor, voltage matcher and speed or frequency matcher units. The converter unit includes means for sampling the generator and bus-bar voltages and deriving square wave signals therefrom which are then combined to form a composite signal indicating the phase difference between the generator and bus-bar voltages. The voltage matcher and speed or frequency matcher units are supplied with the requisite signals and are operative to energize relays to provide increase or decrease voltage orders or to provide increase or decrease speed orders. The voltage acceptor unit receives voltage signals from the generator and bus-bar and provides a signal which, until the generator and bus-bar voltages are within acceptable limits for synchronizing, inhibits the operation of the synchronizer unit so that no signal to energize the circuit breaker is developed.
