  • Patent number: 4491555
    Abstract: A method of providing a dam in a loading coil case for the blocking of an encapsulant solutions penetration into the cable beyond a desired distance by inserting, via a hypodermic needle, a quantity of encapsulant activator at the desired site of a dam. The encapsulant upon contacting the activator jells very rapidly preventing the remaining encapsulant from draining into the cable.

  • Patent number: 4490581
    Abstract: A circuit which controls the selection and activation of one of a plurality of clock circuits arranged in copies. Selection circuitry is used to detect failure of an on-line clock circuit, scan a plurality of available clock circuits in a predetermined sequence and place the next available properly operating clock circuit on line. Control circuitry prevents erroneous clock selection during power-up/power down operations and enables predetermined clock circuit copies to be disabled.

  • Patent number: 4467285
    Abstract: A pulse monitor circuit which detects pulse failures through use of a detection circuit and a storage circuit. The detection circuit detects failure of the monitored pulses after being periodically reset by an external reference pulse train. The storage circuit is clocked by the reference pulses and operates to store the output signals of the detection circuit. Upon detection of a pulse failure to monitor can be cleared by external control or detection of a monitored pulse.

  • Patent number: 4452359
    Abstract: A printed wiring card stiffener bracket comprised of a single piece frame and having slotted tab and fastener arrangements for securing the stiffener bracket to the printed wiring card. The stiffener bracket includes blade arms which bear against the printed wiring card preventing distortion and warpage of the card and assisting in the insertion of the card in a card file. A cover interlockingly engages tabs on the stiffener bracket providing protection to the underlying components and added rigidity to the stiffener bracket.

  • Patent number: 4446437
    Abstract: A pulse monitor circuit which detects failure of a monitored pulse by monitoring its expected occurrence during time intervals defined by an external reference pulse train. Failure of the reference pulse train is detected by monitoring its expected occurrence during time intervals derived from the monitored pulse train. Detection circuits are used to detect failure of the pulse trains and storage circuits, which can be cleared by external control or reappearance of the monitored pulse.

  • Patent number: 4427948
    Abstract: A pulse toggle monitor circuit which detects toggling of a monitored pulse. A plurality of detection circuits are connected in a shift register manner. This arrangement provides for detection of pulse toggling of a duration longer than a predetermined time as defined by the period of an external reference signal and the number of detection circuits. The output of the shift register is connected to a storage circuit which is clocked by the reference signal and operates to store failure signals from the shift register. The storage circuit can be cleared either by external control or detection of a valid pulse.
