Title: Remote control of colour tv receivers
IPC: G08C19/18
Filed: 1972-09-28
Abstract: 1396960 Remote control of radio and TV INTERNATIONAL STANDARD ELECTRIC CORP 28 Sept 1972 [4 Oct 1971] 44780/72 Heading G4H [Also in Division H3] A device for the digital remote control of a radio or T.V. set by successive operating function control steps comprises a receiver (Fig. 1) which generates for each control step a unique number of pulses which are transmitted over a common path to a receiver (Fig. 2) wherein they are counted to provide an output signal which effects the required control step. Depression of a switch KT causes an encoder MA2 to set a bi-stable switch ES1 which signals a multivibrator MU and a differentiator/delay VZ. MU is caused to output pulses U1, the first of which sets the outputs of a counter BZK1 to 1, while VZ produces a signal U2 which actuates a triple electronic switch ES3 to permit MA2 to ground selected ones of the outputs F11-F13 of BZK1: as a result, BZK1 counts (under the control of U1) from an initial value which depends on the selected switch KT. The pulses U1 operate an electronic switch ES2 which controls an oscillator UO to cause an acoustic transducer USG to emit a modulated ultrasonic signal until the count is such that output F 14  changes from 1 to 0: this output (and then output F 15  which changes from 1 to 0 when F 14  changes from 0 to 1) is fed to a gate MA1 which disables ES2. BZK1 continues to count until output F 16  changes to disable switch ES1, after which the transmitter is disconnected unless the switch is still pressed. At the receiver the signal is detected (Mi) and demodulated (DEM) to give a pulse signal U3 which is fed to a counter BZK2. The first pulse of U3 triggers a monostable UN whose output U4 is differentiated to give a signal U5 which enables a switch ES4: the (binary) count in BZK2 passes to a decoder DE which produces the required control step output A. Means (switches ES5, ES6 and burst generator BG)are also provided for transferring output 3<SP>1</SP> from ES4 into an (N-1)-pulse burst for backstepping Modulo-N control counters connected to the outputs A1, ..., A8 of DE, for which feature reference should be made to Specification 1,396,417.

A second hook may be provided for engaging another part of the bead wire and preferably a keeper is provided to prevent the wire becoming disconnected from the hook or hooks. The die may be adjustable for various sizes of bead wires. As shown in Figure 2, the tyre 3 is divided into halves and half a tyre is mounted between the die 1 and the hook 4 which is in a position ready to pierce the tyre. Then the connecting rod 5 is moved in the direction of the arrow so that the hook 4 may pierce the tyre and catch a part of the ring- shaped bead wire 2. Hook 4 continues to move in the direction of the arrows to make the bead wire 2 alone pass through the die. The shape of the die consists of a first part shaped to allow passage of the hook 4 and two slitshaped parts projecting away from opposite sides of the first part through which the bead wire 2 is passed. The die 1 is divided on the line of the slit and made moveable so that the shape of the die may be varied to allow use of the die with bead wires of different diameters. The width of the slits correspond to the diameter of the bead wire 2 so that rubber adhering to the wire 2 is stripped off. As shown in Figure 3 part of the die 1 which passes the bead wire is a ring-shaped slit of width corresponding to the diameter of the bead wire 2 and two hooks 4, 4 are provided which pass through respective suitably shaped parts of the die. In another embodiment (Figures 4, 5 and 6, not shown) there are provided dies and hooks respectively facing each other so as to allow the simultaneous removal of the two bead wires embedded in a whole tyre.

Abstract: 1,262,370. Transistor Class B amplifiers; transmitting systems. MARCONI CO. Ltd. 6 July, 1970 [25 Sept., 1969], No. 47378/69. Headings H3T and H4L. [Also in Division H2] A solid state radio frequency transmitter including a Class B transistor power amplifier 1 has a control means A, B operable automatically if the D.C. supply current taken by the amplifier reaches for a predetermined time a predetermined value less than the maximum available D.C. supply current from the power source D for rendering effective circuit protection means 7 for the amplifier. Normally, transistors A4, A12 and 7 are off and transistor A5 is on. The current drawn by the Class B amplifier 1 produces a voltage drop across resistor 6 which is compared with a voltage set by potentiometer A1, A2 by differential amplifier A4, A5. If the output load current drawn by the amplifier 1 exceeds a predetermined amount for a predetermined relatively long time, e.g. a few seconds, as determined by the time constant of A3, A6 and A8, transistors A4, A12, and 7 turn on and transistor A5 turns off so that transistor 7 shunts the r.f. input 3 to the amplifier. Control unit B is similar to unit A and protects against peak output overload. The potentiometer A1, A2 in unit B is adjusted so that the transistors A4, A12 and 7 require a larger current through resistor 6 to switch them on and the time constant of A3, A6 and A8 in unit B has a shorter time constant. Control unit C prevents secondary breakdown of the transistors in the power amplifier 1. The unit C is similar to units A and B but requires a larger current through resistor 6, than that for a peak overload, so as to obtain an output at C13 and the time constant is made very short. This output from C13 turns on SCR 8 so as to shunt the positive supply D2 from D, which may be provided with a current overload protection. A reflection sensor 5 is provided between the output of the Class B amplifier 1 and the transmitter aerial so that impedance mismatch, such as disconnection of the aerial or load,  causing a reflected power exceeding say 10% operates the transistor 7 via connection 513 so as to shunt the input. In a modification  each of the units A and B may feed its output control signal to a monostable or bi-stable which apply protection, e.g. by rendering transistor 7 conductive and/or cutting off the D.C. supplied to the amplifier 1.
