  • Patent number: 4245150
    Abstract: A power line disturbance (PLD) detector circuit includes a digital counter which is driven by pulses provided by a clock in an associated data processing system. The PLD detector circuit includes a comparator amplifier for comparing primary AC power to a DC reference voltage on a cycle-by-cycle basis. The amplifier generates a reset pulse once during each AC cycle as long as the AC voltage exceeds the DC reference voltage. When a decoder circuit detects a count outside the range of counts attained by the digital counter between normally occurring reset pulses, the decoder circuit responds by generating a PLD signal. The PLD signal is provided both to the associated data processing system and to a Power On Reset circuit. The Power On Reset circuit is initialized by the PLD signal, permitting the circuit to respond consistently upon subsequent restoration of power.

  • Patent number: 4242574
    Abstract: A flexible tape is releasably wound into a coil within a housing. Optically sensed encoded markings along the length of the tape are illuminated by a light source through fiber optic bundles. The light reflected from the illuminated markings is transmitted by additional fiber optic bundles to two light detectors for sensing the markings as the tape is wound or unwound from the coil. The markings are counted as they pass the fiber optic bundles by electronic logic circuitry the output of which controls a digital display on the housing.Two sets of markings are provided along the tape so that the display may be switched between metric and feet and inch units without making substantial changes in the electronic logic circuitry. The electronic count may be reset to zero at any extension of the tape and subsequent readings would then be plus or minus from that extension.

  • Patent number: 4237374
    Abstract: A cutting cylinder of a newspaper press assembly has a magnet member mounted thereon. A semiconductor Hall effect pickoff is mounted in proximity to the cutting cylinder such that the magnet passes by this sensor in close proximity thereto once during each rotation of the cylinder. The output of the Hall effect sensor, which is in the form of pulses, is fed both to a non-inverting and an inverting amplifier. The outputs of the amplifiers are fed to a differential detector which provides an output only in accordance with the difference between the inputs fed thereto, thus eliminating common-mode inputs such as noise signals. The output of the differential detector is fed to a digital counter which provides a count of the input pulses representing the number of newspapers or the like detected by the sensor. The output of the digital counter in turn is fed to a readout device which provides a suitable readout of this count which may be in the form of a display.

  • Patent number: 4234787
    Abstract: An apertured disk which is mounted on a shaft in a loom causes a first photocell to transmit a first signal once during each revolution of the shaft in a preselected angular position of the shaft, and a second photocell to transmit a second signal in response to each incremental angular displacement of the shaft through one degree. A counter is reset to zero in response to reception of each first signal, and the counter thereupon counts the second signals until the shuttle of the loom causes the generation of a third signal which is generated when the shuttle reaches a predetermined portion of its path. The counter displays or otherwise indicates the number of second signals which are generated between the generation of a first signal and the generation of the next following third signal.
