  • Publication number: 20120194101
    Abstract: Electrical component assembly (30) comprising a first electrical component (32) comprising an electrical connection protrusion (34) (e.g., a solder bump) made of a first metal solder composition having a first melting point, and a second electrical component (36) comprising an electrical contact (38). A second metal solder composition (40) having a second melting point is formed or otherwise disposed so as to function as an electrical connection between at least a portion of the electrical connection protrusion (34) and the electrical contact (38) of the second electrical component (36). The second melting point is lower than the first melting point, and there is a distinct interface of demarcation between the electrical connection protrusion (34) and the second metal solder composition (40).

  • Patent number: 5573626
    Abstract: A continuous tape supply apparatus is provided in accordance with the present invention for supplying tape at a substantially consistent tension to a tape applicator machine having an indexing demand, such as a box sealing and taping machine. In general, the continuous tape supply apparatus includes plural tape sources, such as in roll form, from which tape can be supplied to the tape applicator machine, a splicing station for splicing the tape from at least one of the tape sources to another of the tape sources, a means for causing the splice and thus the changeover of tape from one source to another, and a tension control means for providing the tape from the continuous tape supply apparatus at a substantially consistent tension under an indexing demand. Preferably, the splicing mechanism also splices tape in the reverse order from the other tape source station back to the first tape source stations.

  • Patent number: 5536044
    Abstract: An apparatus for binding a plurality of sheets of paper together is disclosed. A pair of clamping plates presents one edge of the sheets for binding after a jogging plate aligns the edges. After a solid hot melt adhesive material sheet is placed along the edge of the sheets, a heating platen heats and melts the hot melt adhesive material sheet and causes the liquid adhesive to bind the sheets together. The method of binding the stack of a plurality of sheets of paper includes positioning a plurality of sheets between the clamping plates, vibrating the sheets to square and align their edges, clamping the aligned sheets of paper, presenting the aligned edge of the paper to the heating platen, placing an adhesive hot melt material sheet on the edge of the sheets, heating and melting the hot melt adhesive material sheet onto the edge, and removing the bound sheets from the apparatus.

  • Patent number: 5507907
    Abstract: A sensor system for use with a taping head of a box sealing machine includes a tape dispensing sensor and an box presence sensor. The tape dispensing sensor is positioned along the tape guide path of the taping head for determining whether tape is being dispensed from the taping head and for providing a positive response if tape is being dispensed. The box presence sensor is positioned on the taping head for detecting movement of an element of the taping head that reacts to the box being moved along the taping head and for providing a positive response if a box is present. A control system is provided and is connected to the tape dispensing sensor and the object presence sensor for determining a potential error condition if only one of the tape dispensing sensor and the object presence sensor provides a positive response. Preferably, three sensors are utilized in the sensor system. One senses tape dispensing, another senses a box presence, and yet another senses tape supply left on the roll.
