  • Patent number: 5072070
    Abstract: A resilient electromagnetic shielding gasket utilizes a plurality of conductive wire coils which are loaded in a manner so that coil spacing may be selectively adjusted at specific areas along the circumference thereof in order to provide an electromagnetic shield. Other portions along the circumference of the gasket provide sufficient biasing capability to take up for variations that may occur due to torquing, eccentricities, irregularities and other variables and thereby imminent contact between mating surfaces under load. The spacing along a seal-load portion of the gasket is selected to limit the passage of electromagnetic energy with a wavelength greater than a selected value.

  • Patent number: 4890937
    Abstract: A cartridge bearing assembly includes a non-resilient tubular bearing element and a spring for causing the tubular bearing element to float with a shaft therethrough within a surrounding housing. Because loading between the bearing element and the shaft is eliminated, very close tolerances can be held therebetween and wear between the bearing and the shaft therethrough is substantially reduced. Seals may be incorporated into the bearing member in applications where a pressure drop is desired across the bearing shaft interface.
