  • Patent number: 7906735
    Abstract: A seal including a base and a conductor mounted to conduct current from a source disposed on a first side of said base to a sink disposed on a second side of said base. In the illustrative embodiment, the base is annular (ring-shaped) and fabricated of airtight, watertight and/or electrically insulating and/or conductive material such as rubber, Teflon®, silver impregnated Teflon®, or other suitable substance. In the illustrative embodiment, the conductor is a single strip of conductive material and the base has a recess to allow for deflection thereof. In the best mode, plural conductors are mounted within the annular base. Each conductor has a brush at each end thereof. The brushes are provided by a split(s) at the end of each strip effective to create multiple fingertips. Each strip is secured at an angle in a slot in the base and retained further by an anchor. The anchor is integral with the strip and transverse to the longitudinal axis thereof.

  • Patent number: 7878814
    Abstract: Electrically conductive bearing retainers create an electrical path between the static and dynamic sides of a rotating joint to block EMI radiation from entering or leaving a system. Concentric annular inner and outer bearing retainers with an array of conductive contact members therebetween are installed in contact with the inner and outer races of a dynamic bearing interface. Each contact member includes a base and tips. The outer bearing retainer ring has a recess for mounting a contact member and a notch for positioning the contact member tips to make contact with the inner bearing retainer ring. The inner bearing retainer ring includes a conductive contact surface. The contact member tips contact the conductive contact surface to create a dynamic shield between an inner bearing race and an outer bearing race.
