Abstract: 503,496. Automatic tuning correction. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BRAILSFORD, J. D. Oct. 5, 1937, No. 26968. [Class 40 (v)] The automatic frequency control of a superheterodyne receiver is made uniform over the entire tuning range by means of an auxiliary control voltage dependent on the setting of the manual tuning, control. In Fig. 2, control voltages from an error detector circuit are applied in known manner to the inner grid G1 of the pentode frequency control reactance VI connected at T1, T2 across the frequency determining circuit of a local oscillator (not shown). A further bias control voltage derived in dependence on the setting of the receiver tuning knob is applied at W to the outer grid G3. The phase-splitting resistance R2 and the valve V1 are enclosed by tubular screens ST, VT connected by earthed screens EP1, EP2. A simple or complex reactanoe X in the cathode lead of VI corrects undesired phase shift. In Fig. 4, the slope of the thermionic control reactance V1 is again controlled by A.F.C. voltages applied to the grid G1, the auxiliary control in dependence on manual tuning being applied to an auxiliary valve V2 which applies positive feed-back, variable by this control, to oppose negative reaction in the reactance V1 due to the resistance R3. The resistance R2 of Fig. 2 may be constituted by the anode-grid resistive impedance of a second control valve, Fig. 6 (not shown). Fig. 7 shows a shortwave arrangement in which the local oscillator V1<11> is controlled by the reactance V1<1>, to the outer grid G3<1> of which are applied A.F.G. voltages. The voltage varying with manual tuning is derived from a rectifier 3 connected through a discriminator or shaping network 4, 5 across part of the oscillator tuning circuit TCO. Alternatively this control voltage could be derived from a logarithmic graded resistance potentiometer conjointly operated with the receiver tuning control. Specification 474,711, [Group XXXV], is referred to.

Filed: 1957-08-27
Abstract: 853,031. Reaction time measuring apparatus. HEYLMUN, S. L. Aug. 27,1957 [Aug. 27,1956], No. 27036/57. Class 81(2) A reaction time tester comprises an electric motor 25 with an output wheel 20, an indicator shaft 3, a solenoid-controlled clutch between the shaft and a gear 5 meshing with a second gear 27 which moves under the control of a solenoid 13 to carry a wheel 17 into and out of engagement with the output wheel. The second gear 27 is fixed to a shaft 28, which is rotated by an electric motor 25 when a wheel 17 on the shaft 28 contacts the output wheel 20 of the electric motor 25. An indicator 67 movable over a dial 60 is carried by the shaft 3 which is coupled to and rotated with the first gear 5 by engagement of a clutch key 22 in a slot 7 in the hub 6 of the first gear 5. The clutch key 22 is slidable in a brake disc 8 fixed on the shaft 3 but is normally held out of engagement with the hub 6 by a first lever 18 which is controlled by a solenoid 12. The shaft 28 carrying the wheel 17 and the second gear 27 (not shown) is mounted on a second lever 14 which is controlled by a second solenoid 13. Brake and accelerator pedals 34, 36 simulating those of a motor car are provided. In use, a switch 31 is closed so that the electric motor 25 is energised, the shaft 3 carrying the indicator 67 remaining stationary. The operator presses the accelerator pedal 36 which closes a switch 32 so that a green lamp 64 lights and the solenoid 12 is energised to lift the first lever 18 and thus release the clutch key 22 and tighten a brake band 21 around the brake disc 8. When after a time which cannot be predicted by the operator the slot 7 registers with the clutch key 22, the latter is pushed into the slot 7 by a spring- pressed collar 10 thus coupling the shaft 3 to the first gear 5. A change-over switch 72 operated by the movement of the collar 10 disconnects the green lamp 64 and the first solenoid 12 so that the lever 18 falls to loosen the brake band 21 and permit rotation of the shaft 3 and the indicator 67. Simultaneously a red lamp 62 is lighted whereupon the operator transfers his foot from the accelerator pedal 36 to the brake pedal 34 which closes a switch 33 to energise a relay 25, which opens the red lamp circuit, and the second solenoid 13 which moves the second lever 14 so that the wheel 17 is lifted out of contact with the output wheel 20 and contacts a stop 16. The wheel 17, gears 27, 5, (not shown) the shaft 3 and the indicator 67 cease to rotate. The total movement of the indicator 67 gives a measure of the reaction time of the operator. On releasing the brake pedal 64, the second solenoid 13 is de-energised and the second arm 14 falls to its starting position, the shaft 3, which is again coupled to the motor, continuing to rotate until a cam surface on the first arm 18 causes the clutch key 22 to be withdrawn from the hub 6. Specification 769,804 is referred to.
