Title: Improvements in or relating to electric motor control systems
IPC: B60L15/04
Filed: 1928-12-17
Abstract: 324,770. General Electric Co., Ltd., and Croft, E. H. Dec. 17, 1928. Series-parallel systems; electric braking; master control sytems.-In a series-parallel control system for a pair of electric tramcar motors, a drum controller has segments and contact-fingers for passing control current to detached electromagnetically actuated contactor switches which make the series, parallel, and reversing connections; and has other segments and contact-fingers acting directly upon variable resistance in the power circuit. Electric braking can be set up by turning the drum controller backwards from its zero position, and also automatically as the result of failure of the line current. The arrangement shown in the Figure for controlling two series motors 1, 2 includes a master reversing switch 5 and a drum controller 30. By turning the drum to position 1 on the right hand side, control current is directed to a winding 99 which closes the series grouping switch 98 conditionally upon the previous closure of both the motor cut-out switches 55, 60. Successive turns to positions 2, 3, 4 short-circuit starting-resistances 45 - - 50 as the stepped segment meets contact-fingers directly connected to resistance taps. At position 5 part of the resistance is reinserted and control current is directed to windings 104, 105 which close the parallel grouping switches 102, 103, the opening of the series switch being brought about before both the parallel switches close. Advance of the controller to the remaining positions shortcircuits resistance as before. If one of the motor cut-out switches has been opened before notching- up, the drum positions are inoperative until the parallel stage has been reached. If the drum is turned from zero to the positions 1 - - 7 on the left-hand side, the motors are connected in parallal in a closed braking circuit from which resistance is progressively removed. The braking circuit is established automatically if the supply fails.

Title: Improvements in and relating to semiconductor devices
Inventor: BENNY ALAN HUGH BERGER
IPC: H01L21/00
Filed: 1960-11-01
Abstract: 998,939. Semi-conductors. MULLARD Ltd. Oct. 6, 1961 [Nov. 1, 1960], No. 37513/60. Heading H1K. In the formation of PN junctions or ohmic connections boron is alloyed as an impurity with copper in a recrystallized zone of a semiconductor material. The invention is applied to produce a high impurity concentration in the emitter zone of silicon power transistors, to improve the forward characteristic of PN diode sections, or to produce low resistance ohmic connections. Whereas concentrations of indium as an impurity in germanium can be achieved comparable with the use of boron with copper, boron has the advantage of a higher segregation coefficient. Copper may be alloyed to the semi-conductor body as a first step and the boron may be added to the melt so produced. In a specific example the copper (9À8 gms.) and boron (0À2 gins.) are sealed in an evacuated silica crucible heated to 1200‹ C. for 10 minutes and then quenched in water. The copper/boron ingot so produced is then sealed in an evacuated crucible with tin (1 gm) and heated at 1100‹ C. for 10 minutes and then quenched in water. The tin/boron/copper ingot so produced is rolled to a thickness of 100 Á and pellets of 1 mm. diameter are punched out. The pellets are then employed on N-type silicon discs beneath 1 mm. discs of tantalum and half gramme weights of iron or silica. The pellets are then alloyed by heating to 780‹ C. for 5 minutes in an atmosphere of hydrogen. The use of tin in the pellet alloy is to reduce a tendency of the resolidified region of the alloy to crack. For this purpose silver, gold, lead, indium, or nickel/lead may be used as well as tin, or some of the semi-conductor material may be used. Alternatively, that part of the melt which would form a resolidified zone is removed by chemical or mechanical means and a separate contact is made with the recrystallized zone.

Abstract: 771,546. Barrel locks. LEGGE & CO., Ltd., J., and LEGGE, F. V. Dec. 12, 1955 [Dec. 28, 1954], No. 37439/54. Class 44. In a double cylinder mortice lock, the aligned cylinders are mounted with their tumbler mechanisms vertically above the common axis of their plugs and with the common axis below that, part. of the deadbolt with which tongues or throwers engage to operate the deadbolt and in which-the tongue or thrower on the inner end of each of the plugs is so disposed angularly that when the pin holes in the plug are in register with those in the cylinder body, the tongue or thrower occupies a vertical position below the common axis. As shown, in which a sliding bolt 19 is actuatable from either side of a lock casing 14 by cylinder locks arranged on a common axis, each of the cylinders is of inverted key-hole shape in cross-section, a part 10 constituting a barrel, housing a key-operated plug 11 and a part 12 housing pin-tumbler mechanism. The plug 11 is provided with an operating tongue 13 for co-operation with a tongue 27 of a bolt lath 20 to move the bolt 19, and a projection 34 on the tongue 13 cooperates with a cross-piece 31 of a security lever 28 pivoted on the bolt. One cylinder is assembled to the lock case 14 by operating the security lever by means of a rod, inserted through a hole 33 and by moving the bolt to a half-shot position by means of a screw-driver inserted to a position below the cross-piece 31 to bring a talon 26 into register with holes for receiving the cylinder parts 12. The cylinder, with the tongue 13 turned into register with the part 12 is then inserted by entering the upper rear corner of the part 12 through the lower part of the correspondingly shaped hole in the lock case and moving it upwardly until it engages the top of the hole, whereby the tongue 13 will support the crosspiece 31 when the cylinder is fully inserted. The cylinder is secured by a screw 15. The second cylinder with its tongue 13 turned into register with the part 12 is assembled to the lock case by being passed axially into its mounting hole and being secured by a second screw 15. The tongues 13 are then turned by the keys to their normal depending positions shown in Fig. 2 to withdraw the bolt. In operation, anticlockwise rotation of either key moves the bolt to the left while clockwise rotation moves it to the right (as seen from the respective sides from which the operations are effected).
