Title: Improvements relating to electric motor control systems
Inventor: BURNETT THOMAS BRIAN
IPC: H02P7/30
Filed: 1957-10-02
Abstract: 875,188. Automatic speed-control systems. ENGLISH ELECTRIC CO. Ltd. Dec. 30, 1958 [Oct. 2, 1957], No. 30835/57. Class 38 (4). [Also in Group XXXVII] Under motoring conditions, armature Ma is supplied from main magnetic amplifier MMA through the control winding of a braking magnetic amplifier BMA and rectifier RBI. When, however, the armature current falls below a predetermined value, the braking amplifier provides an output voltage which is applied to the armature through a rectifier RB2 and a non- linear resistor R. This results in reverse current flow through the armature and thus dynamic braking of the motor. The speed of the motor is automatically maintained at a predetermined value during motoring operation by means of a tachometer generator TG in series opposition with a reference source RS across the control winding of a magnetic amplifier CMA which supplies the control winding of the main amplifier through a rectifier RB3. In a modification, two magnetic amplifiers supply the armature, each through a rectifier and a non- linear resistor. The control windings of the amplifiers are in series opposition across a variable-voltage source. The magnetic amplifiers are rendered effective in turn for driving the motor in opposite directions. Fig. 2 (not shown).

Title: Thermocouple device and method
IPC: G01K1/10
Filed: 1966-07-13
Abstract: A heat-hardenable fibrous ceramic material suitable for coating thermocouple junctions (see Division H1) comprises fibres of, for example, alumina and silica in equal quantities by weight, bonded together by a heat hardenable binder such as a colloidal silica binding agent.  The material is formed from a slurry comprising the fibrous ceramic material dispersed in water.  The binding agent is added in a concentration of 20-25% by weight, based on solids.  The mixture, comprising 30% solids and 70% water, is introduced to a tank provided with a porous felting screen associated with suction means. The fibrous material and the binding agent accumulate on the screen, and when the desired thickness is reached the screen is removed from the tank and suction is maintained until the water content is about 20% by weight and the colloidal silica binding agent content is about 5% by weight on a solids basis.  The material may then be moulded and heat-hardened around the thermo-couple junctions (see Divisions B4-B5).  Other suitable fibrous ceramic materials include mineral or rock wool, beryllia, zirconia, titania, slag wool or quartz. The binding agent may alternatively be sodium silicate, colloidal alumina, colloidal zirconia &c.

Abstract: 500,500. Fluid-pressure servomotorcontrol systems. ARADO FLUGZEUGWERKE GES. Nov. 17, 1937, No. 31578. Convention date, Dec. 5, 1936. [Classes 69 (ii) and 135] In a hydraulicallyactuated device for displacing members such as the landing flaps 7 of aircraft, the pump supplying the working medium to the device is relieved from load by u valve o connecting the supply and return conduits 1, 2 to the device and operated jointly by a member 8 controlling the device and an auxiliary member 9 moved by the flap or other displaceable member so that the valve 5 is open when the flap is in its initial or inoperative position. As shown, the valve 5 comprises a spring-closed ball valve 12 controlling a passage 6 between the conduits 1, 2. The valve may be pushed open by a rod 10 carrying a doublearmed lever 11. The lever 11 is acted on at one end by a hand lever 8 which actuates the control valve 3, 13 of the device and at the other end by a lever 9 linked to an arm 28 on a shaft 17 which operates the flaps 7. The control valve comprises a relatively movable piston 13 and cylinder 3 of which the former is connected by an arm 29 to the shaft 17 and the latter is connected by flexible conduits 15, 16, 21, 22 to the valve 5 and to a working cylinder 4 containing a piston 18 for operating the shaft 17. When the lever 8 is moved clockwise from the initial position, Fig. 1, the lever 11 is turned about its lower end by a spring 34 and the valve 5 closes. Pressure medium is therefore admitted to the cylinder 3 and due to the relative displacement of the members 3, 13 passes to the left-hand end of the working cylinder and moves the flaps to their operative position. The consequent follow-up movement of the piston 13 does not lap the control valve ports completely so that the working medium maintains the flaps in operative position against the air pressure acting on them. The movement of the shaft 17 also moves the lever 9 counterclockwise, the valve 5 remaining closed. To return the flaps to their initial position, the lever 8 is moved counterclockwise to the position shown in Fig. 4. Working medium is admitted to the left-hand end of the cylinder 4 and the lever 11 is moved about its lower end but without affecting the valve 5. The subsoquent rotation of the shaft 17 returns the flaps to their initial position, moves the piston 13 to lap the control valve ports, and rotates the lever 9 clockwise. The lever 11 therefore moves the rod 10 to re-open the valve 5.
