Patent GB-1095320-A (GB)
IPC: H04L25/04
Abstract: 1,095,320. Testing transmission systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Nov. 30, 1964 [Dec. 6, 1963], No. 48507/64. Headings H4L, H4P and H4R. [Also in Division G1] In apparatus for deriving a measure of the distortion in a pulse transmission system the received signal is applied to a device which develops a signal representing the algebraic difference between the instantaneous algebraic value of the signal and the mean of the algebraic value of the signal. In Fig. 2 the signal from the transmission system is applied to the unit 1 to obtain the algebraic value of the signal which is applied direct to one input of the summation circuit 4, and via a low pass filter and an inverter to the other input, the low pass filter extracting the mean value of the algebraic value of the signal. The resulting difference signal is passed through circuit 5, to obtain the algebraic value of the difference signal, and a low pass filter 6 to obtain the distortion representing signal. In an alternative arrangement the mean of the algebraic value of the signal is removed from the instantaneous algebraic value by passing the instantaneous algebraic values through a high pass filter 7. It is suggested that the circuit for converting algebraic values to absolute values may comprise a squaring circuit.

Abstract: 1,239,034. Emergency lighting systems. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION. 7 Oct., 1968 [6 Oct., 1967], No. 47502/68. Heading H2H. Emergency supply system includes a battery which is normally charged by a mains supply, and a number of devices, such as lamps, which are operated by the battery when the mains supply voltage falls. This voltage is detected by a transistor, and another transistor makes or breaks the emergency circuit through a relay or a power transistor. In the circuit shown in Fig. 1, the battery B is normally charged through a transformer Tr, rectifiers D 1 , D 2 , and a pilot lamp Lc. The transistor T 2  is biased to conduction so that the transistor T 1  is blocked and no current flows through the relay Ra. A drop in the mains supply voltage of, say, 50%, results in the blocking of transistor T 2 , so that current can now flow through transistor T 1 , energizing relay Ra and closing a switch K so that emergency lamps Ls1, Ls2 are energized from the battery. The actions are reversed when the supply voltage rises towards its normal value, and the emergency lamps are extinguished. During a period of supply failure, the emergency devices may be turned off either locally by means of a push-button switch P which shorts out the transistor T 1 , or by a remote control method which consists in applying a D.C. voltage to the base of transistor T 2  by way of a terminal 2. The devices may be reactivated by applying a suitable voltage to the base of transistor T 1  through another terminal 3. Resumption of the mains supply over-rides and cancels any preceding actions of local or remote control. In modifications of the circuit shown, the relay Ra and switch K may be replaced by a power transistor, and a further transistor may be used to ensure positive switching of the emergency circuit, Fig. 5 (not shown). Also, the emergency lamps may normally be in series with permanent lamps, Fig. 7 (not shown), and be switched to the battery supply on mains supply failure. The current supplied is insufficient to illuminate the emergency lamps when these are in series with the permanent lamps.

Abstract: 1,256,674. Digital transmission systems. YOKOGAWA ELECTRIC WORKS Ltd. 10 July, 1970, No. 33526/70. Heading H4P. A pair of transmission lines are balanced by impedances having the same characteristic impedance connected to opposite ends of the lines. A pulse transmission circuit causes currents of equal amplitudes to flow in the lines, feeding a receiving circuit having a differential amplifier. Line L1, L2 of impedance Zo are terminated in a resistor RZ = Zo and a balanced potential divider R1, R2, where R1/2R2=Zo connected across a supply Vc and a capacitor C. The arrangement ensures that there are no signal reflections at ends of the lines. A pulse generator Fig. 2A comprises a switching transistor Q1 operating oppositely from constant current transistors Q2, Q3, diodes B2, B3 providing temperature compensation. The receiver Fig. 2B (not shown) reverses the polarity of its output at zero signal input, and in the absence of a signal the bias voltage developed across R1 prevents the potentiasdifference between lines L1, L2 dropping to zero in the absence of a signal.  Any number of pulse transmitters not operating simultaneously, and any number of receivers may be connected across the lines if the input impedances of the receiving circuit are made sufficiently high.
