  • Patent number: 5292559
    Abstract: This invention relates to a method for producing a smooth continuous and adherent pressure bonded or cold welded layer of a metal containing composite on a base or target material through the driving force of a pulsed laser. The method includes the steps of selecting a laser transparent substrate, applying thereto a thin laser absorptive polymeric film characterized by a high optical coefficient of absorption to the wavelength of said laser, applying the metal containing composite to the absorptive polymeric film, and placing the base or target material in close proximity to said composite. The composite is a multilayered composite comprising laser absorptive polymer, gold, nickel and gold-flash, and the pulsed laser energy is directed through the transparent substrate toward said composite and is absorbed by the polymeric film causing heating and vaporization thereof while leaving portions of the polymeric film unvaporized.

  • Patent number: 5265329
    Abstract: A method and product for providing an electrical interconnection between components and a substrate includes the use of an adhesive coating. The coating (40,42) is applied between the contacts (14,22) of component and substrate and the surface of a conductive fiber-filled, elastomeric connector (30) and is operable to bond the contacts to the surfaces of the connector with conductive fibers (34) of the connector piercing the adhesive coating to provide multiple contacts (36,38) and define current paths for the interconnection while mechanically bonding connectors, components, and substrate together. Protective covers (44) are applied to connectors to protect the adhesive coatings prior to use with sheets (50) or rolls (52) alternatively used to carry arrays of connectors in patterns corresponding to substrate contacts (14,22).

  • Patent number: 5259052
    Abstract: A duplex fiber optic connector assembly enables mating the fibers of a first multifiber cable with like fibers of a second cable or cables with maximum axial alignment of the respective fiber paris. An interconnect member receives cable terminating connectors in opposite sides thereof. Each connector carries the fibers of a respective cable in individual ferrules, each ferrule having limited floating mount within the respective connector. The mating pairs of ferrules are received in opposite ends of receptor members each of which has an axially profiled bore adapted to receive the respective ferrules and a profiled outer surface which allows movement about the geometric center of the receptor so as to axially align the bores of the ferrules received therein. Connectors at each end of a predetermined length of fiber optic cable provide a fiber optic extension cord, analogous to the well-known electrical extension cord, for convenient and efficient interconnection between optical signal-using equipments.

  • Patent number: 5253272
    Abstract: A digital data transmission system includes a transmitter connected to a receiver by a twisted pair. A digital transversal filter, included in the transmitter, supplies output signals to one of four resistor banks, as determined by an automatic selection system that selects one of the resistor banks based on the measured transmission characteristics of the twisted pair. The output signals are weighted by the resistors of the selected resistor bank, summed, and used to generate the transmitted pulse. The values of the resistors of each resistor bank are chosen to shape the transmitted pulse for a respective length of transmission medium so that, after distortion by the transmission medium, the transmitted pulse more nearly corresponds to the ideal pulse shape for which the receiver is designed.

  • Patent number: 5247259
    Abstract: A machine for making and testing a cable harness assembly having planar, multi-conductor cable terminated to insulation displacement contacts housed in connectors. The machine includes a test module having a programmed microprocessing unit for executing the testing procedure. A series of manually operable switches are provided, the conditions of which are detectable by the computer. These switches are then set to indicate the number of contacts present in the connectors being terminated and to indicate which of these contact positions are to be tested. Additionally, the order of correspondence of the contacts of one connector to the other connector may be reversed by actuating a forward/reverse switch. The test module includes a learn mode, where a cable assembly of known configuration is placed into the machine. The test module then determines the continuity paths of the cable assembly and uses that information to test subsequently made cable assemblies.

  • Patent number: 5244405
    Abstract: An unkeyed insert (4) removably retained in a electrical connector (2) has a mating portion (44) projecting from a forward face of the connector beside a mating structure (12) also projecting from the forward face of the connector (2). The mating part (44) defines a socket (60) for receiving a screw lock (234) on a mating connector (200). The mating part (44) has an open side (58) closely adjacent to the mating structure (12). By virtue of its rectangular shape, the mating part (44) can only be angularly oriented with its open side facing the mating structure (12). The unkeyed insert (4) cannot be mated with a keyed structure (218) of the mating connector (200) since an end face (62) of the mating part (44) would butt against the distal end of a rib (222) of the keyed structure (218).
