Abstract: A non-contact type coaxial switch that eliminates all contacts and inner conductors. The switch includes a stator/coax base assembly and a rotor. The stator/coax base assembly is fixed, while the rotor is rotatably mounted to the stator/coax base assembly and eliminates all contacts and inner conductors. The rotor is disposed between bearings, and consists of waveguide paths that couple between selected coax connectors. When the rotor is rotated, different selected coax connectors occur. For other arrangements selected, the rotor can switch between a condition of coax and waveguide outputs. The rotor, between bearings, consists of waveguide paths which couple between selected coax connectors. When the rotor is rotated, a different selected coax connector occurs. For other arrangements selected, the rotor can switch between a combination of coax and waveguide outputs.

Abstract: In one embodiment, a latching sector motor actuator includes a housing, a permanent magnet, and a pole piece. The permanent magnet rotates relative to the housing. The pole piece has a polarity and a pair of wound wire coils, is fixedly attached to the housing, and communicates with the permanent magnet to cause the permanent magnet to rotate one of clockwise and counterclockwise, depending upon the polarity of the pole piece. In another embodiment, a failsafe sector motor actuator has a pole piece with a singularly wound wire coil and further includes an auxiliary permanent magnet. The auxiliary permanent magnet is adjustably attached to the housing to extend rotation of the permanent magnet from 80° to 120°, depending upon location and magnitude of the auxiliary permanent magnet.

Abstract: A two-position rotary actuator provides a latching or holding torque which can be adjusted by altering the magnetic properties of a selected pole member. The actuator also functions as a sector motor over a selected range of angular motion and provides failsafe operation which returns the actuator to a starting position when electrical power is removed.

Abstract: A ratchet and ball magnetic index device having a drive motor plate with a top surface and a bottom surface. The drive motor plate contains at least one ball receiving recess on the periphery of the bottom surface of the drive motor plate. A permanent magnet armature is secured to the top surface of the drive motor plate and rotates freely around a rotor shaft. A sector motor rotates the armature and drive plate when turned on. A ratchet plate, attached to the rotor shaft, has a bottom surface and a top surface with a plurality of contours displaced in a circular direction around the circumference of the ratchet plate. Each of the contours has a flat plane connected to an incline plane which is connected to a vertical plane. At least one magnetically attractable drive ball is positioned between the top surface of the ratchet plate and the bottom surface of the drive motor plate, wherein the drive ball moves freely within the ball receiving recess.

Abstract: A switch includes switching elements which are mounted within a sealed radio frequency cavity. The switching elements provide electrical contact paths between contact portions of connectors which project into the cavity. The switching elements are urged against the contacts by magnetic forces. During operation, unselected paths have their switching elements grounded out by the action of external magnets which attract the unselected switching elements to a ground plate with a magnetic force which overcomes the magnetic forces urging the switching elements against the contacts.

Abstract: A device for cyclically enhancing driving torque in a mechanical assembly having a torque driven rotatable body, including a nonrotatable support carrying the body a drive means applying driving torque to the rotatable body fixed magnetic members, and a rotatable magnetic means arranged to react intermittently to enhance cyclically the driving torque applied to the driven body. The torque driven body exerts a flywheel driving effect on the magnetic members to rotate them between angular positions when the magnetic members are not enhancing the driving torque.

Abstract: A microwave waveguide switch assembly comprises a stationary housing having four openings and a cylindrical chamber of housing rotor which has a microwave switch section formed with two cylindrical axially spaced plates at ends of an integral bar to contain the microwave energy between the walls of the rotor and the chamber wall during transmission of microwave energy through selected passages in the housing. The plates and the bar along with the chamber wall provide an essentially sealed microwave passageway thus minimizing transmission losses and at the same time, preventing leakage of microwave energy between passageways.

Abstract: A sector motor has a rotor which is rotatable to one of three positions in a housing. The rotor carries field magnets surrounding stationary armature poles carried by the housing. An arcuate 90.degree. slot in one end of the housing receives an arcuate 45.degree. arm projecting from the rotor thereby limiting the rotor to a total angular rotation of 90.degree.. Spaced latching magnets coact in mutual repulsion or attraction or both to latch the rotor at either end of rotor rotation. The motor's inherrent magnetic restoring force assisted by a magnetic detent carried by the housing and rotor and located midway between opposite ends of the 90.degree. slot latch and prevent vibration of the rotor in a central position between opposite ends of its range of rotation.
