Patent GB-2133941-A (GB)
Title: Switching circuit
Inventor: BESZANT STANLEY GEORGE
IPC: H05B37/02
Filed: 1984-01-30
Abstract: There is disclosed a switching circuit in which DC power is provided by an array of diodes 32, across which there is derived a appropriate voltage. The voltage is rectified by diode 34. The DC circuit includes a time delay circuit 38, 48, 46 which actuates the primary winding of a relay 12. The switch 12A controlled by the relay allows power to flow to the load 11. The time variable of the time delay circuit may be set by a varying value of resistor 38. The load may be switched on by either one of two switches; if the first of the two switches is selected the load is switched on, and is not switched off until a predetermined delay after the first switch has been turned off. Alternatively two switches may be provided, of which the first selects whether or not a time delay is initiated, and the second switches on the power. <IMAGE>

Patent GB-2162617-A (GB)
Title: Valve stem seal
Inventor: BAKE EARL ALLAN
IPC: B41J25/304
Filed: 1985-02-25
Abstract: A circuit and related method are provided for maintaining a desired spacing between an ink-jet printing means and a receiving surface along a line scanned by the printing means. An ultrasonic transducer transmits signals at timed intervals to the receiving surface from the printing means. A reflected signal from the receiving surface is sensed by the transducer during a receiving time window after the signal is transmitted. A reference position signal representative of the head to surface spacing at a printing location is compared to the desired head to surface spacing to produce a position error signal. A servomotor responds to the position error signal to move the printing means toward and away from the receiving surface to maintain the desired spacing.

Patent GB-873022-A (GB)
Abstract: 873,022. Zeroizing-mechanisms. ATVIDABERG-FACIT A.B. Jan. 8, 1960 [Jan. 9, 1959], No. 821/60. Class 106 (1). A totalizer of a calculating-machine has zeroizing mechanism of the type in which a toothed zeroizing rod slides axially in a groove of the totalizer wheel shaft. The zeroizing rod is first moved axially, without movement of the shaft, and the rod and shaft are then rotated together to zeroize the wheels. As described, zeroizing of a totalizer is effected by rotating a toothed segment 7 against the action of a spring, thereby rotating clockwise a toothed wheel 3 freely mounted on the totalizer shaft 1. During this rotation a cam surface 3b engages a tooth 2d on a zeroizing rod 2 to shift the rod 2 axially to the right (Fig. 9) until the tooth 2d strikes an end face 3c of the cam 3b, zeroizing teeth 2b on the rod 2 having now moved into alignment with projections 5a on the interior of the totalizer teeth 5. Rotary movement of the shaft 1 has so far been prevented by the engagement of a further tooth 2a in a slot 4a in a fixed guide member 4, but when the tooth 2d strikes the cam end face 3c, the tooth 2a has moved out of the slot 4a, and rotary movement of the rod 2 and shaft 1 is caused by co-operation of the tooth 2d and cam end face 3c, such movement continuing until the wheels,5 have been zeroized whereupon the mechanism returns to its original state under the action of a spring attached to the segment 7, leftward movement of the rod 2 being caused by the co-operation of a cam surface 3a with another tooth 2c on the rod 2.

Filed: 1988-06-14
Abstract: Apparatus for monitoring a video signal receiver (3, Fig 1) capable of being tuned to a plurality of channels to determine if the receiver is tuned to receive one of the plurality of channels comprises a first sensor 17 to sense the synchronisation signal associated with a selected one of the channels, and a second sensor 20 to sense a signal related to the synchronisation signal associated with the video signal to which the video signal receiver (3) is responding. A phase detector 18 determines the phase relationship between the two sensed signals, and a modulator 22 supplies a delayed form of the synchronisation signal sensed by the first sensor 17 to the video receiver (3). A processor 10 determines whether there is then a change in the phase relationship between the two sensed signals. <IMAGE>
