Patent GB-2217132-A (GB)
Title: Switching circuit
Inventor: MARSHALL ANDREW
IPC: H03K17/0412
Filed: 1988-03-23
Abstract: In a transistor circuit, rapid turn-off of a bipolar transistor 1 is facilitated by connecting the base to a path of controlled conductivity of a second transistor 9 having its control electrode connected to an input terminal 4 and by arranging 9 to become conductive to turn off 1 by increasing the input signal at 4 (normally keeping transistor 1 conductive but not transistor 9) above a predetermined threshold level immediately before a falling transistion of the input signal. Transistor 9 is then turned off when input at 4 becomes sufficiently low. A diode or a zener diode may be included in the bias circuit of 9 for use with smaller input signals. An FET may be used in place of transistor 9 and a Schottky diode may be connected to the gate to delay turn-off of the FET for preventing a short burst of conduction of transistor 1. <IMAGE>

Patent GB-2227768-A (GB)
Title: Cutting machine
Inventor: DAWSON GORDON BERTRAM
IPC: E21C27/22
Filed: 1988-12-16
Abstract: A cutting machine comprises a frame comprising side rails (8, 10) which provides a track way, on which a carriage (20) is mounted for movement back and forth along the frame. The machine comprises a supporting means whereby the frame, and thus the bulk of the machine, are retained at a position raised slightly above the ground. said supporting means comprising two forward support members (80), and a third support member (82) which is afforded by a shoe to which the frame is pivotally mounted on an underside. The support members (80) are each pivotally mounted on the forward frame rail (8), and each are connected, by a link (88), to an hydraulic ram (90). By the application of hydraulic fluid to the ram, the forward support member (80) may individually be moved about its fulcrum, adjusting its height-wise position in relation to the system. Thus by simultaneous movement of the two forward support members (80) in the same direction, the machine may be tilted about a horizontal axis extending parallel to the direction of movement of traverse of the cutting mechanism over the frame, whilst by disparate adjustment of the two former support members (80), the machine as a whole may be tilted about an axis extending at right angles to the direction of traverse. In this manner, the machine may be "steered" to follow the inclination of the seam being worked. <IMAGE>

Title: System for controlling apparatus for growing tubular crystalline bodies
Inventor: MACKINTOSH BRAIN H
IPC: C30B15/28
Filed: 1988-12-19
Abstract: A control system for controlling the operation of an apparatus for growing tubular crystalline bodies. The control system comprises a weight sensor (100) for measuring the weight of the crystal, a pressure sensor (102) for measuring the pressure inside the crystal, and a controller (105) coupled to the weight, length and pressure sensors for controlling the operation of the crystal growing apparatus. The controller is coupled to the die heater (26) of the apparatus for controlling the temperature of melt contained in the crucible (24) of the apparatus based on the outputs of the weight, length and pressure sensors. To ensure the wall of the tubular crystalline body is maintained at a substantially uniform thickness, precise measurement of the weight of the body must be made. Compensation is provided by this invention for weight measurement errors that are created by pressure fluctuations within the tubular crystalline body.
