  • Synchronous sampling system
    Patent number: 4905085
    Abstract: The pixel clock of a system for receiving, sampling, and digitally storing the information contained in an analog sampled-data video signal is automatically synchronized and stabilized so that the received data is sampled by said system at or near the center of each successive received pixel period. A preset counter is employed to determine whether the receiving system clock is running at a predetermined number of pixel periods per horizontal sweep; any variation from the predetermined number is sensed and converted to a DC voltage level which is used to adjust the receiving system clock automatically to the correct number of periods per sweep. Synchronization of the receiving system clock is accomplished by triggering it with the sync pulse portions of the received video signal.

  • Lamination for use in transformers or the like and method of making the same
    Patent number: 4904527
    Abstract: An inexpensive lamination for use in transformers and/or other static or dynamic electric machines has a metallic layer one side of which is provided with a coat of hardenable adhesive and the other side of which is provided with a coat of insulating material. At least the adhesive coat can contain particles of sand, glass, a metallic oxide or a synthetic plastic material; such particles act as distancing elements between the respective side of the metallic layer and an adjacent metallic layer. The two coats are applied simultaneously between an unwinding station for a web or strip of coherent metallic layers and a winding station for the freshly coated web or strip of coherent metallic layers.

  • CMOS cell for logic operations with fast carry
    Patent number: 4905179
    Abstract: The elementary adder, as far as carry propagation is concerned, has two circuit branches: the first is an inverter (II) followed by a transfer gate (T1, T2) activated when two operands have opposite logic levels, in which case it transfers complemented input carry Cin to the output CoutN; the second consists of a 4-transistor series cirucit, two P-MOS (T3, T4) and two N-MOS (T5, T6) geenrating carry output CoutN complemented when the two operands have equal logic levels.

  • Circuit condition monitor with integrally molded test point socket and capacitive coupling
    Patent number: 4904932
    Abstract: A circuit condition monitoring system for an electrical power distribution system includes a system connector component having an integrally molded test point socket within which a circuit module is received to provide fault current or voltage loss monitoring of a system conductor within the connector. The test point socket provides capacitive coupling to the monitored conductor without the use of a metallic test point, and a ground return to the electrically conductive outer sheath of the connector. An electrically conductive end cap may be provided to cover the projecting end of the module when the module is installed in the socket. Adapters installed on the other end of the module enable the module to be installed on prior metallic contact-type test points.

  • Nylon fabrics with cupric salt and oxanilide for improved dye-lightfastness
    Patent number: 4902299
    Abstract: A surprising improvement in dye-lightfastness of dyed nylon automotive fabrics is achieved by a combination of a copper salt and of an oxanilide light stabilizer. The oxanilide is effective with a surprisingly broad range of copper derivatives. Both the copper and the oxanilide may conveniently be applied from the dyebath, or, surprisingly, the copper provides improvements even if melt-spun into the fiber.
