  • Pedestal assembly having an RFI/EMI labyrinth shield
    Patent number: 5216431
    Abstract: A pedestal assembly for rotatably carrying a load containing radio-sensitive equipment is disclosed, with the assembly having a turntable and base. The profiles of the turntable and base adjacent to one another are both stepped and define a tortuous path between them. The assembly further is designed to distribute any attached load directly to a driven bull gear, rather than to the turntable.

  • Pedestal with tilting bearing race
    Patent number: 5090823
    Abstract: A bearing assembly is disclosed in which a bearing having inner and outer races is seated in a manner which accommodates thermal expansion and contraction without allowing radial pressure to constrict the bearing. Two materials of differing coefficients of thermal expansion form the seat for the outer bearing race such that temperature variations cause the race to tilt around the ball of the bearing. The bearing assembly is particularly useful in rotary drive assemblies for antenna pedestals.
