Abstract: A receptacle for receiving a plug includes a frame and an electrical connector mounted on the frame. A switch is electrically connected to the connector and can disconnect it. A manually operable interlock has an on and off position. This interlock is mounted on the frame for operating the switch to apply power to the connector after the securing of the plug into the connector. The interlock has a grasping device for grasping the plug on a rearward external surface of the plug. The grasping device prevents the removal of the plug in response to the interlock being placed in the on position.

Abstract: A high torque rotary electromagnetic actuator is described which includes a U-shaped stator formed from a substantially planar sheet of magnetic iron to have two parallel leg portions joined by a transverse connecting portion. The single piece stator which is so formed is joined to an axial core which is staked or riveted to the stator connecting portion by an intimate or press-fit to minimize reluctance to the magnetic flux flowing through the stator and core. The rotor is mounted on the free end of the core and is provided with cam surfaces for providing variable gaps with relative rotation between the rotor and the stator. The rotor is provided with an enlarged axial hub portion which is configured to compensate for the reduced axial thickness thereof produced by the provision of a counterbore which receives a portion of the core therein.
