Abstract: 777,865. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Sept. 15, 1955 [Dec. 7, 1954], No. 35362/54. Class 40 (3). The datum level of television signals in a circuit including a video amplifier 2, a D.C. amplifier 3 and a television transmitter 4 is maintained constant by means of two synchronizing period datum " clamp " circuits the first comprising diodes 6 ... 9, serving to " clamp " the input signal to amplifier 3 to a reference potential dependent on the departure of the datum level from a desired value such departure error being determined by the amount that the second " clamp " comprising diodes 20 ... 23 is required to return the datum level of the signals (derived from the transmitter 4 and demodulated by means of 19) to a predetermined fixed value set by potentiometer 26. The error signal, which consists of the synchronizing pulses as " clamped by the second " clamp " and the varying amplitudes of which represent the departure error, is derived by amplification and limiting (in 27 and 28 respectively) of the signal at the second " clamp " and supplied to the first " clamp " as a reference potential via a delay device 29 which introduces a delay of about 5 microseconds in order to make the tips of the synchronizing pulses coincide with the back porch of the synchronizing signals in the signal input to amplifier 3.

Filed: 1931-12-23
Abstract: 394,360. Direct-call systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, and BAKER, G. T., Blackbrook, Caerphilly, Glamorgan. Dec. 23, 1931, No. 35592. [Class 40 (iv).] In a system of the kind in which stations can be connected one at a time to an attendant who is able to give information, e.g. stock prices or exchange rates, a single manual operation by the attendant automatically effects the interruption of the connection with one party and the subsequent completion of a connection with a new calling party. The drawings show one line 10, 11 from a station to the positions of several attendants, of which two are shown in Figs. 1 and 2 respectively. Apparatus above the dot-and-dash line is individual to line 10, 11 and that below is common to all lines. There may be several lines from each station to the attendants' positions. When the line 10, 11 calls, relay CL common to the positions pulls up, locks and lights the calling lamp RC at each position. The attendant who answers throws TRK to complete a circuit for M in series with TR which remains inert until M short-circuits its lower winding. CL falls back and the calling lamps are replaced by answering lamps VE at each position. TR holds to a contact of K and connects up the attendant's set, and as the operation of key TRK was momentary, M falls back, operates K and holds TR. If now another calling line is answered by throwing its key TRK, M again pulls up but TR of the new line remains inert because the short circuit about M (lower) is open at K3. The relay TR in the previous call is however released and is followed by K which replaces the short-circuit so that the new call is switched through bv its relay TR. The connection may be released by throwing RLK to operate M. An attendant may call a sub-station by throwing TRK and sending out ringing current.

IPC: H02P7/288
Filed: 1968-07-26
Abstract: 1,270,411. Control of D.C. motors. CLARK STACATRUC Ltd. 14 July, 1969 [26 July, 1968], No. 35691/68. Heading H2J. A battery-fed lift truck is driven by a series motor 10 which is initially supplied from batteries B1, B2, in parallel, the field winding 12 being reversibly energized through contactor F or R. When starting, a resistor R2 is connected in series with the motor, pressure on a pedal operating an hydraulic actuator to compress a carbon pile 19. When a predetermined pressure is reached, contacts CP1 close to short-circuit the carbon pile, and, at the same time, contates CP2 open to de-energize a relay DR which closes contacts DR1 in series with contactor BS after a time delay. Further depression of the pedal causes the batteries to be connected in series through contact BS1, so increasing the motor voltage. An hour meter 34 records the elapsed hours of use of the battery. Movement from forward to reverse is prevented, when the pedal is fully depressed, by means of relay APR which is de-energized as a selector switch DCS is moved from forward to reverse. Contacts APR1 open, and it is necessary to release the pedal and so close contacts MSIA before the reverse contactor can be energized. A pump motor 23 for lifting is brought into circuit by contactor P provided that the switch BS1 is not closed to supply full voltage to the traction motor. The maximum rate of lift is obtainable when the truck is stationary, the switch BS1 being closed under these circumstances. When the motor acts as a generator for braking, a solenoid valve 20 is energized by the voltage generated to compress the carbon pile 19 slightly and so allow a reduced voltage to be applied to the motor.
