  • Patent number: 11955863
    Abstract: A motor assembly includes a stator having a stator core, stator windings, and a routing insulator configured to electrically insulate the stator core from the stator windings; a rotor rotatably received within the stator; and a bearing bridge received at least partially within the routing insulator and including a main body forming a center pocket arranged to support a bearing of the rotor shaft. A circuit board is provided including a circuit board, and an overmold structure forming an annular body on a surface of the circuit board arranged to mate with the main body of the bearing bridge to substantially seal the center pocket from ingress of debris particles.

  • Patent number: 4930941
    Abstract: A customer terminal for a single tube pneumatic system for banking and the like features a two-piece carrier receiver which includes a carrier tray that first moves downwardly from a stationary receiver housing and then forwardly and upwardly to present a carrier in the tray to a customer, the tray and carrier remaining parallel to the receiver housing. The tray is resiliently mounted to the mechanism which manipulates it and the joint between the tray and housing is contoured both to improve sealing between the two parts and to reduce wear on the seal itself. The air pressure/exhaust ports into the carrier chamber within the receiver are disposed between the ends of the chamber in order to provide an air cushion for reducing the shock of an arriving carrier and to prevent loose items in the system from being sucked into the blower.
