Filed: 1971-07-15
Abstract: 1402546 Transducer circuits IMPERIAL CHEMICAL INDUSTRIES Ltd 13 July 1972 [15 July 1971] 33236/71 Heading G1N [Also in Divisions H3 and H4] A transducer controlled variable frequency oscillator comprises a capacitive feedback integrator 12 followed by a Schmitt type switch 10 providing a bi-polar output which switches when the input is a predetermined fraction of and of opposite polarity to the output, and a variable coupling unit including a transformer L 1 coupling the output of the switch to the input of the integrator. Zener diodes 24 limit the output levels of the switch and a resistor R4 in the feedback path of the integrator advances the phase and so steepens the output edges. In order to maintain positive feedback when the output of the transformer is pbsitive or negative the integrator is biased by means of a resistor R5 which may be variable continuously or discretely. The coupling unit includes an amplifier 34 having a feedback circuit matched in time constant to that of the transformer to compensate for low frequency loss. As shown, the coupling is varied by means of a core 32 sensitive to the load or pressure but in Fig. 6 (not shown) the secondary of the transformer feeds into a bridge network which responds to a quantity to be measured to effect the variation.

Filed: 1961-09-18
Abstract: 977,401. Measuring bridges; measuring temperature electrically. KODAK Ltd. Sept. 12, 1962 [Sept. 18, 1961], No. 33420/61. Headings G1N and G1U. A Wheatstone bridge comprises two adjacent fixed equal resistance arms, a third fixed resistance arm, and a fourth arm comprising a resistance transducer R nonlinearly responsive to a physical parameter C in series with a variable balancing resistance B adjustable on unbalance to maintain the total resistance of the arm constant, the bridge being energized from a constant voltage source V c  in series with a variable resistance X so that if V is the voltage across the bridge input and M o  the resistance across the bridge input diagonal at balance: so that if the bridge is balanced at a first level of the physical parameter by adjustment of the balancing resistance, and the value of X is adjusted in positive linear relationship with dR/dC, then on variation of the physical parameter to a second and subsequent level the unbalance current of the bridge accurately represents the changes of the value. The parameter may be temperature T varying a thermistor exponentially therewith so that dR/dC varies linearly with R, or may alternatively be a chemical concentration varying the conductivity of a cell. It is shown that for positive or negative linear relationship between X and dR/dC, X + B = K 2  (a constant) and K 2  may represent the resistance of a potentiometer of which part X is outside the bridge in series with the supply and part B is in series with the transducer within the bridge (Fig. 2 not shown); the slider being connected to complete the bridge circuit and the potentiometer being calibrated in terms of the variable to be measured. Alternatively resistors X and B may be mechanically ganged so that B + X is maintained constant, while at balance the transducer arm and its adjacent fixed resistance arm are equal; the latter being made equal to the maximum transducer resistance. Bridge energization may be D.C. with galvanometer detection or A.C. with phase sensitive rectifier and galvanometer detection. In Fig. 3 a variable source S of direct voltage V is connected to a bridge comprising adjacent preset equal resistors R 1 , a preset resistor R 2 , and a nonlinearly variable resistor B, and unbalance is detected by galvanometer F, and it is shown mathematically that: where I is the galvanometer current and G is the galvanometer resistance so that constant sensitivity for different ranges of variation of R is maintained by corresponding variations of V. The source may be a constant voltage in series with a variable resistor X (Fig. 4) when V = M o V c /M o +X where M o  is the input resistance of the bridge at balance. Differential temperature changes are measurable by utilizing the outputs from two similar thermistor bridges applied in opposition to a single galvanometer. A detailed mathematical analysis and design data are given.

Title: Improvements in or relating to the distant control of guns
IPC: F41A27/26
Filed: 1938-11-17
Abstract: 530,104. Controlling guns; valves. FAIREY AVIATION CO.. Ltd., and HETHERINGTON. J. Nov. 17, 1938, No. 33458. [Class 92 (i)] [Also in Group XXIX] Single-lever distant-control means for a gun or guns comprises a lever 67, Figs. 1 and 5 carrying a plunger 21 which can be rotated in a casing 22 to control a motor or cylinder (not shown) for say training the gun, the casing itself being rotatable by the handle in a spigot bearing 51 for controlling a second motor (not shown) for say elevating and depressing the gun. Further, the plunger may be pushed into and out of the casing for controlling motors moving the gun into and out of a stowed position and for locking the gun in the operative and stowed positions. Fig. 4 shows the assembly of the control handle 67, plunger 21, and valve casing 22 pivotally mounted in the fixed bearing 51. The desired movements of the gun are effected by motors as described in Specification 530,045, the ports 37 being connected to the motor for raising and lowering the gun, the ports 44 to the locking motor, the ports 38 to the training motor, and the ports 55 to the elevating motor. Pressure fluid enters the valve casing at port 34 and exhaust takes place at ports 35, and 45. A master valve 32, slidable in the plunger against the action of a spring 33 when the part 72 of the handle is grasped, serves to control the admission of pressure fluid to the central space 23 of the plunger from which lead ports for controlling the various motors. Fig. 1 shows the position of the handle and plunger for the stowed and locked position of the gun. To raise the gun to firing position, the handle is grasped and the plunger pushed to the left. Pressure is first supplied through port 40 to the cylinder 41 to release the locking-bolt 42 which is then held by a catch 90. Further inward movement of the plunger causes pressure fluid to pass through port 37 to raise the gun, and projections 68 on the plunger pass into the annular space 70 on the casing. The ports on the plunger 21 are arranged as shown in Fig. 11 so that the turning of the plunger in this position against the action of centralizing springs 77, Fig. 5, controls the training motor. Turning of the casing in the bearing 51 against the action of centralizing springs 57 controls the passage of pressure liquid through ports 49, 50 to the elevating motor as shown in Fig. 13.

Abstract: 1,133,441. Pulse modulation circuits. THORN AUTOMATION Ltd. 17 Nov., 1965 [17 Aug., 1964], No. 33536/64. Heading H4L. [Also in Division G3] The square wave output of a circuit 21 is applied to a transistor TR26 so that the collector connected terminal of a capacitor C is maintained at zero potential during the positive half cycle of the square wave. During each negative half cycle of the square wave the transistor TR26 is cut off and the capacitor C charged, through a resistor 30, to a potential dependent on the bias voltage from a stabilizing circuit 27. The capacitor discharges through a resistor R and after a time interval, approximately proportional to the bias voltage, applies a positive potential to a transistor TR27. The negativegoing signal from the transistor TR27 initiates the generation of a pulse from the pulse former 24. The arrangement is used in a template following system, see Division G3, wherein the output from the pulse former 24 is applied to vary the phase of control signals applied to phasesensitive rectifiers in dependence on the deflection of a tracer so that the movement of a tracer-head is at right angles to the feeler deflection.
