Abstract: 981,930. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 27, 1963 [March 13, 1962], No. 7901/63. Heading H1K. A monolithic semi-conductor device comprises within a unitary body of semi-conductor material, a tunnel diode and a load resistance. As shown, an N-type germanium dendrite 37 is heated in an arsenic atmosphere to produce a heavily doped surface area 36. A sphere 39 of gallium doped indium is then alloyed to one end to produce a tunnel junction 42. The dendrite is then soldered at 48, 60 to a ceramic base. The middle portion is then etched by sodium hydroxide solution to remove the low resistivity surface caused by the heavy doping, and thereby providing the necessary resistance. A bridge member 56 soldered to the ceramic base provides contact with the tunnel diode 39. Appropriate leads are taken from the soldered portions. In an alternative embodiment, requiring no etching, the crystal is suitably masked with silicon oxide, to permit diffusion only to those parts requiring degenerate doping. Other materials which may be used are silicon, silicon carbide, or compounds of Group III and V (e.g. gallium, aluminium or indium, and arsenic phosphorus or antimony). For the sphere 39, boron, aluminium, gallium or indium may be used. The sphere may also include suitable neutral metal. Specification 889,058 is referred to.

Title: Improvements relating to Shot Blast Equipment
Inventor: SHUMSHERUDDIN ALI ANSER
IPC: H02P29/00
Filed: 1966-05-20
Abstract: 1,177,927. Automatic current control. TILGHMAN WHEELABRATOR Ltd. May 19, 1967 [May 20, 1966; Feb.21, 1967], Nos.22586/66 and 8118/67. Heading G3R. Shot blast equipment includes an impeller driven by an electric motor for projecting the shot, a control valve for controlling the rate of mass flow of shot and a controller for controlling the control valve in one or more discrete steps in response to an error signal dependent on the rate of mass flow, the controller including means for gating the error signal in response to a squarewave signal each mark of which enables one control step to be effected and each space of which provides a time interval for the control to take effect. As shown, shot blasting equipment includes an impeller 2 which is driven by a motor 1 and which is fed with shot from a hopper 3 by way of a valve 4 so controlled that the load on the motor 1 is maintained constant. A signal representative of the motor current is derived from a current transformer 6 and a rectifier 7 and is applied to a comparator 8 which also receives a reference signal from potentiometer 9; the error signal from the comparator 8 is applied by way of Schmidt triggers 1, 2, defining permissible upper and lower limits, to AND gates 14 and 15 each of which also receives an input from a multi-vibrator 18 generating squarewave signals of fixed mark/space ratio. The output from AND gate 14 is applied to the valve motor 5 over a forward driving relay 16, and the output from AND gate 15 to a reverse driving relay 17, but the output from the appropriate AND gate is only present during the "mark" period of the signal from multi-vibrator 18, allowing a time interval for the control to take effect during the "space" period so that hunting and over-control are avoided. If the error signal is large the "mark" period should preferably be relatively long to allow the control action to be completed, so a modulus converter 21 and a pulse-width modulator 19 are provided so that the mark/space ratio of the square wave inputs to the AND gates 14, 15 is varied in dependence upon the error signal. A single controller may be associated with multi-plexing equipment arranged to switch the controller from one shot blaster to another so that a plurality of equipments may be controlled. The system may include over-riding controls to enable equipment to run up to speed quickly at start-up and to brake quickly at shut down. A suitable circuit arrangement for the control system is described with reference to Fig. 2 (not shown).
