  • Patent number: 6647620
    Abstract: A center bond flip chip device carrier and a method for making and using it are described. The method includes forming a seat with a cut out portion in at least one trace on a substrate and providing an elastomeric material over the substrate. The seat is sized and configured to receive a conductive connecting structure. The elastomeric material has a gap at the seat to allow electrical connection of the conductive connecting structure with a semiconductor die.

  • Patent number: 4277885
    Abstract: Apparatus for the manufacture of circular wreaths, such as Christmas wreaths, is adapted for making either single-faced or double-faced wreaths, utilizing either artificial or natural wrapping materials.Disclosed is an apparatus or machine for securing facing materials to an elongated, straight wire core to form a wreath section capable of being joined end to end with other similar sections in a separate, subsequent assembly operation to produce a circular wreath of selected diameter. The machine includes means for feeding a wire core in the direction of its length, while imparting intermittent rotational movement thereto about its own axis, with each such movement being on the order of approximately of angular travel about the core axis. The opposite sides of the core are thus alternately presented to the operator for positioning of the wreath facing material in longitudinal contact with the core.

  • Patent number: 4255924
    Abstract: The method and apparatus for producing pipe cleaners each of which comprises two wires which have been twisted into interlocking spirals with fiber elements clamped between the wires. Two primary wires pass through a spinning head and three continuous strands of fibers are wound into spirals covering the wires. Holding wires are passed against the spiral strands upon opposite sides as the entire assembly moves between a pair of pulleys. As the assembly emerges, the fibers are cut diametrically of the spirals to form two continuous rows of fiber elements. Each row is clamped to its adjacent primary wire by a holding wire thus to form a workpiece. Each workpiece passes through a transfer assembly in which the row of fiber elements is clamped to a pulley by one of the wires while the other wire passes along a free loop around pulley and thence back to the row of fiber elements in the wire holding them.

  • Patent number: 4171850
    Abstract: Pipe cleaners comprising a plurality of short pieces of threads as active elements are formed in machines arranged in pairs. Threads are wound in helices around two rigid wires, which are advanced adjacent and parallel to each other and each belong to a different one of the machines of the pair. The turns of the helices are severed between the wires in such a way that two pieces of thread are formed of each turn. Half of the thread pieces are secured to each wire by approaching one additional wire to each of the firstmentioned wires and twisting the wires pairwise for clamping the thread pieces between the wires of each pair and for forming two pipe cleaner strings, which are subsequently cut into individual pipe cleaners.The common parts of the machines of a pair comprise thread bobbins, thread winding means, thread severing means and means for guiding the thread helices forming wires.

  • Patent number: 4117582
    Abstract: Process for winding and unwinding a parallel wire strand consisting of a multiplicity of individual wires onto and from a cable drum, and apparatus for performing such process. In the winding process, the parallel wire strand which is supplied in generally circular cross-sectional shape is fanned out so as to form a layer or layers of individual wires disposed in generally parallel position. The lead ends of the wires are anchored and such anchored end is mounted in a support therefor in the interior of the drum in such a manner that the subsequent winding of the individual wires in layers on the drum is without tension. In the unwinding operation, the individual wires are reformed into such circular cross-sectional strand shape at the bridge construction site, with corrosion-preventing material being applied to the individual wires during such unwinding, and a tubular casing of metal or plastic subsequently formed around the wires for sealing the same.
