Title: Voltage drop detector for telephone line - uses transistor as comparator to drive LED indicating presence of call when predetermined voltage drop is sensed
IPC: H04M3/30
Filed: 1981-04-28
Abstract: The telephone lines (L1,L2) are connected via input pins on a printed circuit (1) to a diode bridge (D1-4) and resistive voltage divider circuit (R1,5). This circuit drives the base emitter circuit of a transistor (Q3) which determines the threshold level at which the circuit operates. This transistor drives a switching circuit (3) comprising two transistors (Q2,Q1) connected across a battery (4) in series with an LED (5). A high value resistor (R2) in the base of the switching circuit input transistor enables the current flow from the battery to be adjusted to a value below which the LED does not illuminate until the fall in voltage on the lines exceeds the predetermined threshold value. A resistor (R3) in the switching stage collector circuit is adjusted to ensure the LED illuminates when the threshold value is exceeded.

Title: Gear train comprising pinion and crown wheel - has complementary teeth on exteriors of both elements but with differing angles between flanks of teeth
IPC: B25B33/00
Filed: 1981-05-12
Abstract: The gear train comprises a cylindrical pinion which has external teeth defining three cylindrical surfaces - a head surface, a primary surface and a foot surface. The teeth are spaced at equal angles and the individual tooth flanks are set at an angle (a) w.r.t. one another. A toothed crown wheel also has equiangularly spaced teeth defining parallel head, primary and foot surfaces. The tooth flanks converge towards the axis of the wheel at an angle (a') which is greater than the angle (a) of the pinion tooth flanks.

Title: Resistance welding of very thin metal wire onto metal support - where wire is pressed onto support by cylindrical object making point contact with wire
IPC: B23K11/00
Filed: 1981-05-13
Abstract: The support is connected to one pole of an electricity supply so it forms an electrode(a), on which a thin wire(b) is placed. A round metal cylinder, esp. a wire(c) is placed on wire(b), so the longitudinal axes of the two wires are at 90 deg. w.r.t. each other. An electrode(d) of opposite polarity to the support(a) to weld wire(b) to the support(a). Cylinder(c) may be partly round, and/or may form an integral part of electrode(d). When the cylinder(c) is a wire, it is pref. made of Ni-Cr not welding to wire(b) or to the support(a). Alternatively, wire(c) may be welded to wire(b) during the process. A pref. application is the mfr. of an explosive igniter, where Cu wires(c) are soldered to conductor wires made of a Cu-Ni alloy. Only a point contact is made between wires (b,c) so the distortion of wire(b) can be avoided if required. Alternatively, wire(b) may be forged or flattened during welding.

Title: Optical device for determining electrical state of power line - has sensor emitting optical pulses whose frequency is function of voltage
Inventor: LEFEUVRE SERGE
IPC: G01R15/22
Filed: 1981-08-11
Abstract: The device contains a sensor (12) which is intended to come into electrical contact with the line. This sensor (12) gives an optical signal which represents the voltage on the line. A receiver (14) includes a detector for the optical signal and a display. The sensor (12) contains a voltage-to-frequency converter which produces an optical signal formed by pulses whose frequency is an increasing function of the voltage of the line. The receiver (14) contains a counter for the pulses received by the detector. The device is partic. useful to verify that a high or very high voltage power line, - typically 63 kV to 400 kV -, is at ground potential. The pulses are counted over a predetermined number of periods of the power waveform e.g. 100.

Patent FR-2498864-A1 (FR)
Inventor: HINN WERNER
IPC: H04N9/20
Filed: 1982-01-25
Abstract: The subject-matter of the invention is an arrangement, used in a system processing video signals, for automatically monitoring and controlling the blanking current (black-level current) of a picture reproduction tube. During periodic monitoring intervals in which no picture signals appear, an output signal is generated at the cathode of the picture tube which is proportional to the black level of the cathode current. This cathode signal is produced as a reaction to a grid control pulse applied during the monitoring interval. The cathode signal produced is processed in a digital signal processing circuit (70, 76, 77) in order to generate a control voltage which changes step by step and which, if necessary, changes the cathode bias voltage in such a direction that a desired value for the black level cathode current is obtained. To prevent the system from starting to oscillate in the vicinity of the correct cathode bias voltage, the grid control pulses (GP2) are given a special shape in particular development of the invention.
