Title: Improvements in television receivers
IPC: H04N5/10
Filed: 1936-11-04
Abstract: 484,412. Television receivers. MURPHY RADIO, Ltd., and FAIRHURST, H. A. Nov. 4, 1936, No. 30041. [Class 40 (iii)] The frame-frequency deflecting oscillator is tripped by an impulse derived from an interruption in the frame synchronizing signal and whose amplitude is determined by a circuit which discriminates between long frame and short line synchronizing impulses, so that only an interruption following a frame synchronizing impulse is effective. The synchronizing signals are isolated from the picture signals by a double diode 5 ; the line and frame synchronizing signals occurring in resistance 6 are applied over 9 to the line deflecting oscillator ; the condenser 10 is discharged over resistance 3 by the synchronizing signals to a degree depending on their duration so that on their cessation the current in resistance 11 reverses to charge the condenser over resistance 7, and the initial value of this charging current depends on the potential of the condenser 10, so that the current is larger following a frame synchronizing signal, and the potential applied to the grid of valve 12 is therefore higher, and valve 12 is rendered conducting only by an interruption following a frame synchronizing signal. The double diode may be replaced by two diodes in parallel, and the output of valve 12 may be phase reversed by a diode, Fig. 4 (not shown). Instead of condenser 10, an inductance may be used, its current reaching an amplitude determined by the duration of the synchronizing signal, Fig. 5 (not shown).

[Class 69 (ii)] In a progressive speed change gear comprising a hydraulic pump 7<SP>1</SP> between the driving shaft 1 and the driven shaft 6<SP>1</SP> and a hydraulic motor 7 acting on the driving shaft, there is provided one canal only through the driving shaft for liquid under pressure forced by the pump into the motor, while the inlet 16 of the pump and the outlet 17 of the motor are connected with each other by means exterior to the gear. The shaft 1 drives by gears 3, 4 a rotating casing 5 in which the motor pistons are connected to an eccentric 10 on a fixed shaft 6. The pump casing 5<SP>1</SP> rotating with the casing 5 houses the pump pistons which are connected to a fixed eccentric on the driven shaft 6<SP>1</SP>. The driving shaft 1 produces rotation of the whole block 5, 51 but the resistance of the apparatus being driven tends to produce a difference in speed between the shaft 6<SP>1</SP> and the casing 5<SP>1</SP> causing the pump 71 to pump liquid through tubes 121, 12 into the motor 7, the eccentricity of the eccentric 10 being adjusted in accordance with the output torque required. The eccentric comprises two eccentric rings rotatable on each other, the smaller one being rotatable on a fixed cylindrical member eccentrically disposed with respect to the axis of rotation of the cylinder unit, the rings being angularly displaced in opposite directions for varying the stroke of the motor pistons. Rotation of the eccentric rings is effected by longitudinal displacement of a transverse pin passing through a longitudinal slot in the fixed cylindrical member and through two helicoidal slots of opposite directions cut in one and the other of the two said rings. The longitudinal displacement of the pin is effected by a control rod 21 which forms a manometric piston submitted to the pressure of the discharge from the pump 7<SP>1</SP>.
