Abstract: 1,135,458. Controlling vehicles. PRIESTMAN BROS. Ltd. 27 Sept., 1967 [7 Oct., 1966], No. 44974/66. Heading B7H. [Also in Division F2] A joystick control lever 1 for a civil engineering machine is spring-urged to an upright neutral position, and carries a magnetic member 14 which is adapted to co-operate with a surrounding magnetic member 13 in order to hold, or assist in holding, the joystick in a displaced position to which it is moved. The lever 1 is pivotally mounted on a ball 3 and carries a plate 6 which engages four spring- pressed plungers 7 which are adapted to operate pneumatic valves 10 arranged to control four separate motions of the machine in which the joystick is fitted. The magnetic member 14 is mounted on the joystick 1 so as to be adjustable axially. The magnetic attraction between the members 13, 14 in any direction is determined by the initial spacing of the members 13, 14 in that direction. When the joystick is moved backwards or forwards the respective valve 10 is depressed to cause engagement of a clutch or brake on a hoist rope drum. When the joystick is moved to left or right one of the other two valves 10 is depressed causing clutches to be engaged to drive crawler tracks either forwards or backwards.

Title: resistance measuring circuit
IPC: G01R27/02
Filed: 1973-09-26
Abstract: 1403818 Measuring resistance COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 26 Sept 1973 [28 Sept 1972] 45102/73 Heading G1U An unknown resistance R x  (e.g a resistance thermometer) is measured by passing through it a current whose value is determined by the variable ratio 3 of an A.C. supply 2 and comparing this current with that from a constant current source whose magnitude is determined by the A.C. supply voltage and at least one standard resistor. Amplifier A 2  is arranged to have substantially unity gain and thus the voltage at point. A follows the output voltage from the resistive or inductive voltage divider 3. When detector 4 indicates null, point B is at earth potential and thus the current through R x  is determined by the divider ratio. The current from the constant current source is to a good approximation -e/R 4  and thus R x  can be found. In order to remove quadrature phase signals due to the inductive nature of any of the resistances, a quadrature signal may be subtracted from the circuit output to counteract any error Fig. 2 (not shown) In Fig. 3 (not shown) only a single standard resistor (R s ) is used to supply the constant current, although this necessitates a floating D.C. power supply.
