    摘要： A wire wrapping tool comprises a head 10 which is formed integrally with a shaft 11. The head 10 includes a frusto-conical portion 16 which has a chordally extending portion cut away to define a cutting edge 22. A blade portion 18 is formed on the head, the blade having a slot 44 through which a wire can pass. The head also has an axially extending bore 34 into which a wire wrapping post can be inserted. In use the shaft 11 is attached to a pistol gun to rotate the head. Wire from which the insulation is to be stripped is passed over the edge 22, through the slot 44 and around a wrapping post. As the wire passes over the edge 22 a longitudinal slit is formed in the insulation which is then stripped away from the conductive core as the wire passes through the slot 44.

    摘要： The invention relates to the location of contact faults on electrically conductive cables such as telephone pairs. Contact fault location apparatus has a pair of resistors (24, 25), a constant current source (22) and means such as a differential amplifier (30) and meter (35) for sensing the current flowing in the resistors (24,25). A pair of lines (10,11) to be tested is looped at one end (15), the apparatus is connected across the other end and the current flowing in the resistors (24, 25) is measured. The ratio of the current is indicative of the distance to the fault.

    摘要： A control unit for establishing a four-wire connection between two terminals via a pair of telephone lines 21, 22, comprises switching means 24 which are operable to provide a connection to a pair of telephone lines 21, 22, signalling means 10 connectible to said lines via said switching means 24 to enable another control unit to be signalled via a line, and line send and receive circuitry 28, 29 connected to the switching means. The line send and receive circuitry 28, 29 has an input for connection to the send channel of a terminal and an output for connection to the receive channel of the terminal. A central control 82 controls operation of the switching means 24 and line send and receive circuitry 28, 29 to automatically establish a four-wire connection and adjust parameters of the line send and receive circuitry to compensate for loss on the telephone line.

    摘要： Control apparatus for a semi-conductor laser device. Apparatus for controlling the emission wavelength and power of a semi-conductor laser device in which the laser driver (5) is connected in a feedback loop comprising a beam-splitter (6), a photodiode (8) and an amplifier (19), which loop controls the driver (5) to maintain the intensity of the laser emission constant. The emission is also sampled by a beam-splitter (7) and a photodiode (9), which is made frequency-dependent by a filter (10) interposed in the path of the beam. The outputs of the matched photodiodes (8) and (9) are fed via amplifiers (11) and (13) to the positive and negative inputs of a subtractor amplifier (12), the output of which is therefore dependent only upon the emission wavelength. This output is fed as negative feedback to an amplifier (15) for controlling an operating parameter (such as the temperature) of the laser (1) to maintain the wavelength constant.
