Abstract: 1,065,182. Semi-conductor devices. GENERAL ELECTRIC CO. April 5, 1965 [April 22, 1964], No. 14373/65. Heading H1K. A PN junction containing semi-conductor body with a film of oxide over the junction is encapsulated with a non-ionizable insulating material separating the encapsulant from the body. The insulating material is chemically non-reactive with the encapsulant, semi-conductor body and oxide. An oxide passivated silicon planar transistor (Fig. 4) has its collector region gold-soldered to a steel or " Kovar " (Registered Trade Mark) strip 20 which is then mounted on one of the wires of a header. The aluminium emitter 18 and base 16 electrodes are fixed to the other header wires via gold wires 26, 28 thermocompression bonded to them. After coating the silicon body and adjoining parts with the particulate insulating material 44, e.g. by dipping in a slurry of boron nitride particles or a mixture of feldspar, air-floated clay and bentonite and drying, the assembly is encapsulated in epoxy resin, glass or lead. The encapsulating, particulate insulating, and header materials preferably have thermal expansion coefficients matched to that of silicon.

Abstract: 585,882. Converting. PLESSEY CO., Ltd. July 28, 1944, No. 14460. Convention date July 29, 1943. [Class 38 (ii)] A vibrator circuit for stepping up D.C. voltage comprises a transformer 12 with centretapped primary and secondary windings 12a, 12b, a D.C. source 11 connected between the centre tap of the primary winding and the common contact 15 of a vibrator with two side contacts 16, 17 alternately engaged by the common contact, which side contacts are connected to the ends of the primary winding and a full wave rectifier, the D.C. source and rectifier output being effectively in series across the load. The rectifier comprises two further side contacts 18, 1‹ connected to the outer ends of the transformer secondary, whereby as the vibrating contact 15 alternately touches contacts 16, 17 to produce impulses through the respective halves of the transformer primary 12a, an alternating voltage is induced in the secondary 12b, half of which is effectively added to voltage of the D.C. source when contacts 15, 18 touch ; and another. similar half is added when contacts 15, 19 touch. Thus, the D.C. voltage across the load 24 between contacts 13 and 13a is equal to the sum of the voltage of the D.C. source 11 and the average of the rectified voltage induced in the halves of the transformer secondary. In a modification. Fig. 2 (not shown) the rectifier contacts 18, 19 may be replaced by a vacuum tube rectifier having two anodes connected to the outer ends of the secondary winding 12b.

Inertia governors. - In inertia governor adapted to cut off the supply of fuel to an internal - combustion engine when a certain speed is exceeded is provided with two inertia elements which come into action at different speeds, one acting to cut off the fuel supply, and the other to restore it. In the form shown, a lever 1 oscillated by the engine through an eccentric or like rod 6 is formed with a head 11 in which are pivoted a pair of inertia bodies 9, 15 carrying pawls 12, 17 and acted on by springs 13, 18. The pawls when swung outwards engage projections 25, 26 on a lever 20, which is fitted with a braking-device 21 and connected by a rod 22 to the suction or bye-pass valve of the fuel pump. Adjusting-means 23, 24 are fitted to the springs for varying the speeds at which the pawls come into action. ' Fig. 2 shows the position of the pawls during normal running, the pawl 12 being extended to engage the projection 25 so as to maintain the lever 20 in the lower position I, in which the pump is supplying fuel. At a speed slightly below the maximum, the pawl 12 is retracted, and when the maximum is reached, the pawl 17 swings out and co-operates with the projection 26 to raise the lever 20 to its upper position II and cut off the fuel supply. As the speed falls again, the pawls take up the former position and restore the fuel supply. In a modification, the springs are so adjusted that the pawl 12 operates at a higher speed than the pawl 17; or they may be set to act at the same speed. A plurality of sets of inertia bodies may be arranged to cut out the engine cylinders successively.

Title: Improvements in internal combustion engine starting mechanisms
IPC: F02N13/00
Filed: 1924-06-23
Abstract: 238,990. Harris, R. June 23, 1924. Machine guns. - A device for starting engines by means of an explosive cartridge, has the firing means for the cartridge connected to actuating means on the engine cam shaft, so that a series of cartridges is fired. A cartridge holder 1 communicates with the cylinder 15 by means of a spring- loaded valve 4, and a sliding breech-block 9 is movable by means of a rock-shaft 49, actuated by a control lever moving over a quadrant and carrying an arm 53 in engagement with a projection 17g on an operating member 17 secured to the breech-block. The member 17 is adjustably secured to a member 18 actuated by a cam 20 on the cam shaft 46 and reciprocating on a guide 23 against the action of a compression spring 25. The cartridges 3 are stored in a magazine 43 and the inward movement of the breech-block 9 moves a cartridge into firing position. A firing pin 27 is struck by a pivoted hammer 28 cocked by the backward movement of the breech-block and held in position by a pawl 31. The rear end of the pawl 31 is held by a tripping member 35 on the member 17 when this is in its extreme forward position. At starting, the pointer 46a is adjusted to the starting position and the control lever is moved into the " breech locked " position, allowing the spring 25 to bring the members 17, 18 into the forward position with the roller 22 in engagement with the point 20<a> of the cam. The breech 9 is thus moved forwards and is locked to the frame 1 by a member 12, Fig. 9, controlled by a member 37 adapted to be released by a cam 17f on the member 17. On moving the control lever into the firing position, the pawl 31 is released by an arm (not shown) on the shaft 49 and the hammer 28 strikes the firing pin, firing the cartridge and giving an impulse to the engine. The rotation of the cam shaft then returns the members 18, 17, 9 and the cartridge is withdrawn by an extractor and ejected by a member 41. The trigger 28 is cocked and the members 17, 18, 9 continue to reciprocate and to fire successive cartridges until the starting lever is returned to its initial position. Reference has been directed by the Comptroller to Specification 19279/05, [Class 7, Air and gas engines].
