  • Patent number: 4626231
    Abstract: A one piece sheet metal pulley has a support structure for rigidly affixing the pulley to an end of a rotary shaft. The pulley includes a peripheral surface, a web, and a hub integrally formed of a single metal sheet. A plurality of protrusions are raised from the hub, each protrusion being a portion between two spaced slits bent upwards to hold the shaft end. The bent-up portion is contiguous with the sheet metal hub at opposite ends of the slits and is raised axially from the hub intermediate the ends, the protrusions bearing radially against the shaft adjacent the shaft end. A bolt hole is centrally provided in the hub for inserting an axial bolt through the hub and into the shaft, and a rotation preventing means having an eccentric attachment means on the hub resists relative rotation.

  • Patent number: 4262259
    Abstract: A magnetic amplifier having two saturable reactor cores with a separate excitation winding on each connected in series opposition, a common control winding and a common output winding, is adapted for use as a low level signal transducer by exciting the separate excitation windings in push-pull mode through a center tapped transformer, and including at least one diode in series with a load resistor connected to the output winding. A resistor in series with the output winding and load resistor is connected between the center tap of the excitation transformer and the connection between the two excitation windings of the saturable cores. This series resistor provides a return current path for the output winding and allows the excitation windings of the saturable cores to operate as primary windings of transformers.

  • Patent number: 4213064
    Abstract: Redundant operation of counter modules is maintained by detecting the zero state of each counter and clearing the other to that state, thus periodically resynchronizing the counters, and obtaining an output from both counters through AC coupled diode-OR gates. Redundant operation of counter flip-flops is maintained in a similar manner, and synchronous operation of redundant squarewave clock generators of the feedback type is effected by connecting together the feedback inputs of the squarewave generators through a coupling resistor, and obtaining an output from both generators through AC coupled diode-OR gates.

  • Patent number: 4150425
    Abstract: A module failure isolation circuit for paralleled inverters senses and averages the collector current of each inverter power transistor and compares the collector current of each power transistor with the average collector current of all power transistors to determine when the sensed collector current of a power transistor in any one inverter falls below a predetermined ratio of the average collector current. The module associated with any transistor that fails to maintain a current level above the predetermined ratio of the average collector current is then shut off. A separate circuit detects when there is no load, or a light load, to inhibit operation of the isolation circuit during no load or light load conditions.
