Title: Cathode ray tube voltage supply
IPC: H04N3/185
Filed: 1968-10-17
Abstract: In a power supply circuit for a cathode-ray tube, the focus electrode 115 is supplied by rectifying at 165 the flyback pulses induced in a transformer 153, the focus voltage being arranged to follow changes in the E.H.T. voltage by means of a circuit such as 183 which inhibits conduction of rectifier 165 during the first half of each flyback pulse and permits conduction during the latter half of each pulse to an extent dependent on the magnitude of the E.H.T. voltage. As shown, each sweep is provided by discharging capacitor 131 through the primary winding 153a of the line output transformer 153 under control of thyristor 127 and is terminated by each pulse from the blocking oscillator 121 which turns on the commutating thyristor 141. The E.H.T. supply is provided by rectifying the flyback pulses at 157 whilst a screen supply for the cathode-ray tube is similarly provided by rectifier 159 which supplies 1000 V. across capacitor 163. The flyback pulses have a double-peaked waveform shown at A due to tuning of the E.H.T. system to a harmonic of the flyback frequency, the second peak tending to reduce in proportion to the reduction in E.H.T. voltage (as shown in broken lines) following increase in E.H.T. loading. A further oscillation B is provided by a ringing circuit 183 connected to the primary 153a and is fed to the cathode of the focus supply rectifier 165 so as to inhibit its conduction during the first peak of waveform A and permit conduction during the second peak so that the focus voltage follows changes in E.H.T. voltage. The focus voltage may be adjusted by resistor 173 which alters the bias on the further focus rectifier 171. In Fig. 1 (not shown), transformer 153 is replaced by an autotransformer driven by a pair of parallel-connected line output transistors. A single thermionic diode (67) provides the focus supply, its cathode being fed with a differentiated version of the flyback pulses (provided by a capacitor and voltage-dependent resistor) so that the focus voltage follows changes in E.H.T. voltage. Fig. 3 (not shown) relates to line output transformer construction, the filament of the focus rectifier being supplied with a single turn winding the capacitance of which is arranged to differentiate the flyback pulse. Fig. 4 (not shown) relates to a line output transformer construction having a ringing circuit inductively coupled to the primary and connected to the anode of the focus rectifier so as to provide tracking according to the invention.

Filed: 1969-03-06
Abstract: A tandem hydraulic brake actuator for a split system using two separate hydraulic pressures supplied at 30, 32 comprises a main piston 14 responsive to one of the pressures and a floating piston 24 responsive to the difference between the two pressures to move also in a brake-applying direction when one system fails, and an automatic adjuster between the two pistons and means for reducing the pressure area on the outside of the floating piston. The device for adjusting the spacing of the two pistons for pad-wear, comprises a thread 38 projecting from the piston 24 and engaging a threaded sleeve 40 slightly movable in piston 14 and is rotatable against ball-bearing 44 and under the non-return effect of a coiled spring 48 to continuously take up slack. A pin 36 prevents rotation of piston 24. Under normal conditions, floating piston 24 is held back by the suction of a pin 34 in a blind hole 35, the pressure being applied at space 28 to the main piston. But if pressure at 32 fails, pressure at 30 into space 26 pushes the piston 24 against piston 14 to effect braking. Part of the active face of piston 24 may be shrouded off (Fig. 3, not shown) to hold this piston back under normal conditions without using the pin 34. In a modification, (Fig. 3, not shown), the floating piston 25 is carried on a piston-rod, 60 in Fig. 4, which extends out of the casing for mechanical hand-brake operation by cam 70. Fig. 4 shows the application to reaction frame disc brakes, the end of bore 18 is not integral but is itself a piston 22a which abuts a frame 80.

Title: Electro-magnetically operated friction clutch or brake
IPC: F16D65/18
Filed: 1977-07-19
Abstract: A fixed part of a clutch (1) comprises a magnet body (2), a permanent magnet (3), a coil of an electromagnet (5) and a nonmagnetic insert (4). An armature (19) comprises an armature disc (12) which is made up of two concentric rings and is connected firmly in terms of rotation to a driver (18) via an annular spring (11). Between the fixed clutch part (2, 3, 4, 5) and the armature (19) there is an axially fixed but rotatable clutch disc (15) which has a deflector (8), a nonmagnetic intermediate layer (9) with an insert (10) and a hub (17). A nonmagnetic intermediate layer (16) is arranged in the hub (17), concentrically to the axis of the hub. In the deenergised condition of the coil of the electromagnet (5), the magnetic flux lines of the permanent magnet (3) follow a path (26). In the excited condition of the coil, the magnetic flux lines follow a path (22) while the flux lines of the electromagnet (5) follow a path (21). The nonmagnetic intermediate layer (16) and the nonmagnetic insert (4) reduce the magnetic leakage flux to a minimum. A fail-safe clutch or brake with a high torque and a short response time and with small dimensions is thus created.
