  • Patent number: 4217542
    Abstract: A self inverting gauging system for such parameters as capacitively sensed distance or inductively sensed resistivity in which the sensor provides an output inversely varying with the dimension of interest. The gauge typically includes a dual slope integrator responsive to a reference value on the up integration and to the sensor output on the down integration. The interval of the down integration necessary to reset the integrator to the original value varies directly, rather than inversely, with the dimension of interest and is typically provided as the digital output indication of a counter. In the application to resistivity gauging, the up integration reference signal is preferably provided by the output of a thickness gauge such that the ultimate counter display represents element resistivity compensated for thickness.

  • Patent number: 4217494
    Abstract: Method and apparatus for isotope separation by selective ionization of a desired isotope in an environment of plural isotopes without corresponding ionization of the other isotopes in the environment. The selective ionization is achieved through a three step excitation of atoms of the desired isotope in response to laser radiations applied to the environment. The transition for each step is selected to be less than one half the ionization potential for the isotopes to avoid two step nonselective ionization.

  • Patent number: 4215802
    Abstract: A needle valve nozzle is employed in a hot melt adhesive gun used to apply thermoplastic adhesive. Actuation of a trigger mechanism supplies pressurized gas to a nozzle chamber which urges the nozzle in an outward direction to an open position, the needle remaining stationary during operation of the nozzle. Deactuation of the trigger mechanism stops the flow of pressurized gas to the chamber and a vent allows the pressurized gas to flow from the chamber, permitting a spring-biasing mechanism to return the nozzle to a closed position. Pressure on the adhesive can also be employed to urge the nozzle to an open position.

  • Patent number: 4210814
    Abstract: Apparatus to reduce pyrophoricity in deposits collected upon collection plates within a chamber employed for vapor deposition. The apparatus is preferably employed in a chamber utilized for isotopically selective photoexcitation, ionization and separation of metallic uranium vapor. The uranium vapor which collects on all surfaces exposed to it within the chamber is caused to collect in a relatively dense, non-porous body by maintaining a suitably elevated temperature for those surfaces while at the same time keeping the chamber itself cooled. The elevated temperature is achieved by baffles shielding the collection plates from the cooler chamber walls to reduce thermal radiation thereto and/or by applying additional thermal energy to the plates.
