  • Patent number: 5045756
    Abstract: An electric discharge device has a conductive shell mounted in a non-conductive tube. A non-conductive collar can mount in the conductive shell. The collar includes an annular neck and an annular flange. The neck is encircled by a central annular groove located between a spaced pair of circumferential plateaus. The plateaus are radially dimensioned to fit in the conductive shell. The annular flange is coaxially affixed to and radially larger than the annular neck.

  • Patent number: 4781641
    Abstract: A tool for making bases for three-way lamps in which it is easier to feed lead wires through because the tool has a first projection in the middle of its base which projection has a round cross-section of a given diameter in the plane perpendicular to the tool's longitudinal axis and a second projection having a cross-section in the forementioned plane having a longer circumferential dimension than a radial one and in which the circumferential dimension is at least as large as the diameter of the first projection in the forementioned plane.

  • Patent number: 4283214
    Abstract: A method and apparatus for forming and delivering insulating glass in gob form to a lamp base making machine from a continuous stream of molten glass. A rotating dial severs the glass stream into uniform gobs and during rotation forms the gobs into a ball like form and delivers the gobs to a pair of radially spaced drop points for delivery to the base shells on an indexing base making machine.

  • Patent number: 4255642
    Abstract: A method and apparatus for tipping off the refractory metal tubulation of a high pressure sodium discharge lamp arc tube including a machine which repetitively squeezes the tubulation through two pairs of sequentially reciprocating jaws to mechanically swage the tubulation to a reduced diameter prior to electrical flashing to cause separation and sealing off of the tubulation.
