Abstract: An antenna assembly for a radio includes an antenna shaft which is translatable between a retracted position and a protracted position. The antenna shaft is translatable through a support tube which is affixed in position with the radio. A detent engages with the antenna shaft to maintain the antenna shaft in either the retracted or the protracted position.

Abstract: A battery housing base (300) with an integral, sliding channel mechanism (507) for attaching a battery to portable electronic equipment (102) is disclosed. The slide-on battery (105) is captivated by limited travel guide rails (307 through 312) within the sliding channels (507) along each opposite edge of the mating surface (302) of the battery housing base (300). Indentations (313 through 316) are disposed between neighboring limited travel guide rails (307 through 312). The indentations (313 through 316) enable the limited travel guide rails (307 through 312) to be manufactured using a single shot injection, straight pull ejection molding process and to be easily attached to the portable electronic equipment (102). The single shot injection mold process controls all critical interface dimensions on the battery housing base (300) for proper attachment to the portable electronic equipment (102).

Abstract: Method and apparatus are disclosed for printed circuit board assembly wherein optimal placement of components are effected. Components, such as microminiature components, are placed, at least on the underside of the circuit board, whereby specially contoured solder pads effect a self-alignment of such components prior to their being affixed in place by a suitable adhesive material.

Abstract: A housing having a central bore therein receives a rotor rotatably mounted therein and secured thereto having an enlarged round base portion. A thrust plate is mounted for limited axial reciprocation within a recessed opening in the housing concentric with the rotor and adjacent the rotor base. The rotor base and thrust plate are formed with cooperating detents and notches to provide indexing means for rotationally positioning the rotor. The internal recess of the housing and the exterior of the thrust plate are configured with matching shapes to prevent rotational movement therebetween, rotation of the rotor moving the detents from one pair of diametrically opposed notches to the next adjacent pair of said notches, while the thrust plate reciprocates against the action of a biasing means. The lower end of the rotor carries a contactor mounted for fixed rotation therewith and having a pair of downward extending arms.
