Title: Outer conductor fault location in telecommunication cables - uses pulse interrogation technique and remote amplifier gain control
Inventor: APEL RUDOLF
IPC: G01R31/11
Filed: 1976-04-30
Abstract: In order to locate cable faults, a sequence of pulses is induced in the live amplitudes of which at one end of the line give an indication of the amplifier nearest which any fault lies. This technique is already in use, though not to locate outer conductor faults, and two remote amplifier gain control circuits are described which allow the method to be extended to this case. The control circuit switches the gain control element of the remote amplifier (RST) to a fixed voltage when the supply current is reduced. This consists of two comparator linear amplifiers (IC1, IC2), the first with a hysteresis characteristic (Rb) and a number of voltage defining diode and resistance chains. These switch current to a heating element (R13) near a gain defining thermistor (RST) to give the control required. The second circuit, which is similar, switches the amplifier gain to a fixed level when the supply current is increased.

Title: PBX circuit for monitoring connections - which are applied to extension with connection broken by counting pulse, depending on output state of timer
Inventor: SCHMITZ RICHARD
IPC: H04Q3/62
Filed: 1976-06-29
Abstract: The extension line is entitled only to local or short distance calls. Time counting in this range is done by charge pulses much wider spaced than pulses used for long distance connection. When the first counting pulse is received, released by the connection completion, a timer (Z) is started measuring at least the time interval corresp. to max. pulse spacing. Depending on the output state of the timer during this period, a further incoming counting pulse disconnects the connection. The timer (2) is controlled by an internal pulse (TG) through a gate element and feeds signals to a flip-flop (R-K) to a security switch (S).
Patent DE-2636600-A1 (DE)
Title: Taped data carrier drive synchronisation - is performed by deriving sync. pulses from data carrier markings and feeding two pulse trains to forward and reverse counter inputs
Inventor: WAWRA HELMUT DR ING
IPC: G03B31/04
Filed: 1976-08-13
Abstract: The content of the counter is compared with a preset rated value and the data carrier drive is readjusted accordingly if the counter content deviates. During the search, the rated value is read into the counter and the counter is fixed at this rated value. The data carrier drive is stopped at the start of the first synchronous pulse generated by the marking of the data carrier. The counter can then be cleared for counting by a counter content corresponding to the rated value. The synchronous pulses are fed to a retriggerable single-shot sweep circuit. A diode can be used to prevent the sweep circuit from being retriggered.
Patent DE-2638616-A1 (DE)
Title: IC engine ignition system - uses triggering signal whose slope and amplitude vary with engine speed to turn on thyristor which blocks transistor
Inventor: BEUTER RICHARD
IPC: F02P1/08
Filed: 1976-08-27
Abstract: Ignition energy is generated by a magnet system driven by the engine and moving relative to the ignition coil, whose h.v winding is connected to at least one spark plug. In order to generate the h.v, the current in the primary winding is switched by a transistor whose base is controlled by a triggering signal induced in an additional control winding. In order to control ignition instant, the trigger signal whose slope and amplitude vary with the engine speed, makes a thyristor (5) conducting at a set threshold. It blocks the transistor (9) in series with the primary winding.

Title: Cold dwell dyeing of carpets - using dye baths contg. wetting agent to improve dye penetration
Inventor: BECKER ERNST J
IPC: D06P3/24
Filed: 1977-01-05
Abstract: In a process for dyeing carpets with acid-, dispersion-, metal complex and/or other cationic dyes, the dye is fixed by the cold dwell process in which the treated carpet is placed on a rotating mandrel with the exclusion of air. The dye compsn. used contains a wetting agent and opt. an anti-foam agent, and is free from foaming agents. Compared with prior art cold dwell deying processes for carpets using a foamed dye compsn., the present agents penetrate more completely down to the base of the pile and into the pile fabric itself, and give more even dyeings with improved moisture resistance.
