  • Patent number: 5750212
    Abstract: This invention relates to a process for the application of conducting metallic, structured coatings on glass substrates, for example, for the manufacture of integrated circuits. The invention relies on placing a negative mask of the structure to be applied into the beam path of an excimer laser. After leaving the mask, the laser beam is directed onto a flat silica glass slice, the back side of which is in contact with a reductive copper bath. The process according to this invention requires exposure times no longer than seconds, after which the process proceeds autocatalytically. It can be stopped as soon as the desired coating thickness has been attained.

  • Patent number: 5543718
    Abstract: A device for testing pairs of wires in a cable which includes a testing console having known means for performing tests on the wires and having a test fixture with a plurality of pins extending through a mating surface, the pins being arranged and arrayed to enter holes containing wires to by tested in a terminal fixture, the terminal fixture having holes into which wires may be inserted and held by friction, the holes opening in a terminal fixture having the holes in the same array as the array of pins in the test fixture so that when the terminal fixture and the test fixture are brought together with the same orientation the pins extending from the test fixture enter the holes in the terminal fixture and make a circuit between the testing console and the wire, and the console includes a rotating switch arrangement to bring both ends of each wire into circuit with testing equipment consecutively and one-at-a-time.

  • Patent number: 5408225
    Abstract: A machine such as a centrifugal pump has a rotating impeller which may get out of alignment if there is bearing wear or if the impeller becomes loose on its supporting axle. A misalignment sensing probe and switch may be installed through the housing of the pump with it probe tip in close proximity to the impeller's face. If the rotating impeller migrates out of alignment it will abrade the tip of the sensing probe. Inside the probe body there is secured a stranded insulated electrical conductor with one of its ends in the tip while the other end extends beyond the other end of the body and is connected into an electrical circuit. Abrasion of the tip will force contact between the stranded electrical conductor wire and the body of the probe. This closing of the switch will activate the electrical circuit which has been designed to shut down the power source and/or activate an alarm and thus avoid destruction of the pump.

  • Patent number: 5367797
    Abstract: Establishing that pressure-influencing factors other than leakage of gas have stabilized before testing the integrity of a vessel in a system including the vessel, a reference vessel that can be connected to and isolated from the vessel, a common source of pressurized gas, a gauge to measure the difference between the vessel pressure and the reference vessel pressure and a computer capable of recording a series of pressure-difference measurements and mathematically manipulating them, the method including equalizing the pressures in the two vessels, then isolating them from each other for a preselected time period, then recording the pressure difference between them at the end of the time period, again equalizing the pressures and repeating that sequence until the pressure difference at the end of two consecutive time intervals is the same, thereby establishing that pressure-influencing factors other than leakage have stabilized.
