Title: Improvements relating to frequency meters
IPC: G01R23/00
Filed: 1930-11-13
Abstract: 363,785. Valve generating circuits. KOLSTER-BRANDES, Ltd., Cray Works, Sidcup, Kent.-(Kolster Radio Corporation ; 200, Mount Pleasant Avenue, Newark, New Jersey, U.S.A.) Nov. 13, 1930, No. 34186. [Class 40 (v).] A frequency meter in which a tuned circuit is maintained in oscillation by an oscillation - generating valve is provided with a piezo-electric control circuit which may be brought into operation for checking the accuracy of the meter. A piezoelectric crystal element 5 is connected between the grid of a valve 1 and a tuned circuit comprising an inductance 7 and variable condenser 8. A high resistance 6 is connected across the electrodes of the piezo-electric crystal unit 5. A winding 9 in the plate circuit of the valve 1 is coupled with the inductance 7 and is connected to a tuned branch circuit comprising an inductance 11 and condenser 10 and adjusted to oscillate at the frequency of the piezo-electric element 5. The coupling between the circuit 7, 8 and winding 9 is so adjusted that highfrequency oscillations may be sustained. The piezo-electric crystal 5 is ground to oscillate at a comparatively low frequency, for example 50 kilocycles, the branch circuit 10, 11 being adjusted to a corresponding frequency. The circuits 7, 8, 9 respond to a frequency range of, for example, 3000 to 4000 kilocycles. As the inductances 7, 9 are small the impedance to the low-frequency oscillations of the crystal 5 is negligible. The capacity 10 is sufficiently large to have negligible impedance to the high-frequency oscillations, so that the valve circuits may oscillate at both frequencies simultaneously. Beat tones are produced as the circuit 7, 8 is tuned through harmonics of the low-frequency oscillations of the crystal 5, providing a means of calibration. By closing a switch 14, the oscillations of the crystal 5 may be stopped when not required for calibration.

Title: Improvements in or relating to Differential Braking System for Reeling Apparatus
Inventor: SCHOLFIELD MAX WENDELL
IPC: H02P3/24
Filed: 1968-07-18
Abstract: 1,171,428. Control of two A.C. motors. INTERNATIONAL RADIO & ELECTRONICS CORP. 18 July, 1968 [31 July, 1967], No. 34268/68. Heading H2J. [Also in Division G5] In a magnetic tape recorder, the reels are driven by split-phase motors 20, 21 and, when switch 38 is actuated to energize the motors for recording or reproducing, current is supplied through switch 40 and circuit 41 to the motor 20, the switch 40 being connected to terminal 31 or 32 for selecting the magnitude of the supply voltage. The circuit 41 inserts resistance into the circuit of the motor 20 after it has started. The voltage applied to the pay-off motor 21 is reduced by resistor 42 to a low value, whereby the motor acts as a drag to hold the tape taut. When switch 38 is released, direct-current from terminal 34 is applied to motor 21 which is braked. The braking current is also applied through lamps 45 to the motor 20 so that less braking is applied to this motor which is coupled to the reel on which the tape is being wound. The lamps 45 act as a resistor having a positive temperature coefficient, whereby the differential braking action increases until the motors are stopped. Switches 37, 38 are actuated for fast forward operation, the motor 20 being connected to high-voltage terminal 31 and the motor 21 to the low-voltage terminal 33. For rewinding operation, switch 36 is operated along with switch 38, in which case motor 21 receives high voltage and motor 20 receives low voltage to act as a drag. When switch 38 is released, the motor 20 receives maximum braking current whilst reduced braking current is applied to the motor 21. The switches 36, 37, 38 may be operated by a relay system controlled by push-buttons.

Abstract: 343,455. Spray carburetters. JAMES, F. A., 35, Parkdale, Wolverhampton. Nov. 11, 1929, No. 34327. Addition to 326,541, [Class 7 (iii), Internal-combustion engines, Carburetting-apparatus &c. for]. [Class 7 (iii).] The parent Specification describes a carburetter wherein the fuel discharged from the nozzle is decreased as the suction increases, by a valve in the nozzle actuated by a plate against which the air stream impinges. According to the invention, the valve is in the form of a sleeve caused by the air current to slide over the nozzle body. The mixing chamber A has an air inlet B, and a throttle valve the spindle C of which is actuated by an arm D. The nozzle body M has an axial bore N communicating by radial ducts P with an annular groove Q above which the body is tapered. A sleeve S is adapted to slide over the nozzle, and has a flange T loaded by a weak spring a bearing against an adjustable head W. The upper edge of the sleeve co-operates with the tapered portion of the nozzle to control the fuel flow. As the throttle approaches full open position, an arm E, Fig. 1, thereon encounters a stud H on a spindle F and causes a head K, Fig. 2, to depress the flange T and enlarge the fuel orifice during heavy load. In a modification, the nozzle body is parallel throughout, and the fuel outlet is controlled by an inverted triangular slot in the sleeve.
