  • Pipe seal capable of use with a filter bag and the like
    Patent number: 5948249
    Abstract: A sealing device 2 for forming a seal against an object such as a pipe surface 12 comprises a sealing strip 6 having a deformable inner pad 8, which is held tightly on the object by a slide fastener 18. The fastener 18 is preferably a hermetic zip fastener. A sealing device of the present invention may be used with a filter bag and the like.

  • Electrical inter-connection method
    Patent number: 4323759
    Abstract: To permit ball-bonding of wires of aluminium or aluminium alloy to small electrical circuits or components, a spark discharge is created between the end of the wire and an electrode in a shielding atmosphere with a peak current density in the wire section which is from 40 to 450 times that used for ball-bonding gold wire. In this way oxidation of the ball is prevented.

  • Bonding method and apparatus
    Patent number: 4098447
    Abstract: Difficulties in forming a ball on the end of a wire of aluminium or aluminium alloy for ball bonding are overcome by applying between the wire and an electrode a low voltage, typically 30 volts, and bringing the wire and electrode into temporary contact to fuse the wire and initiate a spark discharge which results in the formation of a ball on the wire end. The spark discharge takes place in a shielding gas to avoid oxidation of the ball.
