[Class 38 (v)] A load-break disconnect switch suitable for 15 Kv. circuits comprises a moving main blade 3 and an arcing blade 9 pivoted to it at 10, and a latching means holding the latter in engagement with the fixed contact 6 during the initial opening movement of the main blade and against the action of an opening spring 9b, the latch being tripped to produce opening of the arcing blade and an air-blast across the arc thereat. The main blade 3 comprises a pair of blades cooperating with fixed contacts 7, one on each side of an arc chute 8 enclosing the fixed contact 6 and arcing blades. The latching means comprises an overset spring-toggle 15, 16, having a pin 18 engaging a slot 19b in a lug 19a on blade 9, and pivoted to a lever 21 which is urged about its pivot 22 on blade 9 by a spring 23 to the position shown. When the main blade is moved to open the breaker, blade 9 follows until arrested by a roller 19 on pin 18 enjoying a catch 20 formed on the arc chute. Future movement of 3 stresses spring 9b until, at a safe distance, the knee 30 of toggle 15, 16 is pushed to the right by an extension 29 on a piston 25 which is secured to the main blade 3 at 28 so as to be moved along a cylinder 24 secured to blade 9. Buckling of the toggle moves roller 19 clear of catch 20, whereby the spring 9b opens blade 9, the cylinder 24 overtaking the piston 25 and directs an air-blast across the arc-space, and the toggle is reset by the part 28. A further catch 20a ensures an air-blast in case the switch, having moved to within arcing distance in reclosing, is reopened and draws an arc. The back surfaces of both catches 20, 20d are formed so that, in closing, the reset toggle can move bodily downward against the action of restoring spring 23.

Title: Switching circuits
Inventor: WRIGHT MAURICE JAMES
IPC: H03K17/73
Filed: 1963-05-29
Abstract: 1,031,471. Transistor switching circuits- JOSEPH LUCAS (INDUSTRIES) Ltd. May 12, 1964 [May 29, 1963], No. 21399/63. Heading H3T. [Also in Division G3] An oscillator supplies switching-off pulses to the gate of a gate-controlled semi-conductor rectifier except when a turn-on signal is applied to the gate. In Fig. 1 (not shown), in the absence of switch-on signal at 23, a capacitor 21 periodically charges through resistor 16 and discharges through a four-layer diode 17, the discharge current providing a train of negative pulses to maintain non-conductive a gatecontrolled rectifier 15. A positive signal at 23 will switch-on the rectifier and also will render a transistor 18 conductive to terminate the supply of switch-off pulses. Fig. 2 shows a D.C. motor 34 connected as the load of a gate controlled switch 35 and coupled to a generator 56. When the negative output from the generator exceeds a given value a Zener diode 54 conducts, cutting-off transistor 42, so rendering 41 conductive and cutting-off a Zener diode 43. Accordingly, a capacitor 47 repeatedly charges from a current source 48 and discharges through a four-layer diode 45 producing negative pulses at the gate of the gate-controlled rectifier 35 maintaining it cut-off and the motor unenergized. If the generator output is below the given negative value, Zener diode becomes non-conductive allowing transistor 42 to conduct and thus causing transistor 41 to be cut-off. Current through 39 and 38 cause the controlled rectifier 35 to conduct and the motor to be energized. Zener diode 43 now conducts, by-passing the charging current from 48 so that the generation of cut-off pulses by the capacitor and fourlayer diode is terminated.

Abstract: 986,734. Rollers. BTR INDUSTRIES Ltd. June 6, 1962 [June 16, 1961], No. 21817/61. Heading F2U. In a roller for high temperature and pressure operations (e.g. for embossing leather cloth) comprising a non-resilient supporting core of mild steel, cast iron, brass or metal on concrete, and a cover of silicone-rubber or a blend of silicone rubber and one or more heat-resistant elastomers, e.g. "Neoprene" or "Hypalon" (Trade Mark), the cover is reinforced by an openstructure textile material close to, but not in direct contact with, the core. The core of generally cylindrical shape may have a smooth or rough outer surface. The textile material, e.g. leno or mock-leno, scrim, mull, net or cord fabric, may be pre-woven or knitted or applied in a non-structural form in the construction of the roller; alternatively the textile material may be introduced into the silicone rubber or silicone rubber/elastomer composition in long or short staple fibre form in a suitably organized pattern. The textile material may be of cotton, nylon, "Terylene" (Trade Mark), rayon, amixture of these, glass, or metal wire. The cover material may be free from the normal additional compounds or components, e.g. antistatic agents or adhesives; alternatively, if desired, reinforcing materials such as solid particles, short strands of natural or synthetic fibres or heat-resistant compounds such as inorganic fillers or epoxy resins may be included in the core material. The roller may be produced by first applying a thin layer (e.g. a coating or calendered sheet) of silicone rubber around the core which may be coated with adhesive material such as Chemlock 607, second wrapping with one or more layers of the textile material which may comprise an openweave cloth frictioned and skim-coated with silicone rubber so as to be impregnated therewith, or alternate layers of silicone-rubber sheet and cloth may be applied, and finally applying a thick coating or calendered sheet of reinforced or unreinforced silicone rubber. In a further method consisting of continuously feeding a soft grade silicone rubber composition into a nip between a rotating prepared core and an idler roll until the desired coating thickness is obtained, the cloth is introduced after the initial desired thickness has been achieved, the final coating of silicone rubber is then applied until the final thickness is obtained, and finally a tape of Terylene, nylon or cotton is then wound around and the composition is cured at a temperature of 140‹-250‹ C. for one or two hours in steam or air. A secondary heat treatment may be given.
