Abstract: An electrical circuit and method for providing electrical coupling from a CB antenna to both a CB (Citizen's Band--Class D) transceiver and to an AM-FM receiver (amplitude modulation--frequency modulation) whereby only a single antenna need be used for both CB transceiver and AM-FM receiver.

Abstract: An aural-visual display system especially suitable for visually displaying a number of items, such as products, and playing a recorded message relating to a displayed item in response to actuation of a selector corresponding to the item. One of a number of different messages on a magnetic tape are selectively played by changing the positional relationship between a magnetic pickup and the message location on the tape, in response to operation of a selector. This concurrently produces a visual display associated with the selected item to which the message relates.

Abstract: A high-efficiency loudspeaker with a split voice coil and directly coupled push-pull audio amplifier circuit, especially useful when energized through a single-ended, low voltage, external power source to increase the output of a relatively low-power audio amplifier without undue distortion.

Abstract: A mirror assembly for a motor vehicle, in which a mirror backplate is angularly adjustable by an electric motor and drive mechanism. The mirror backplate is pivotably connected to a motor drive casing with a secure yet releasable interconnection that includes a central stud on the backplate, locating structure for the stud on the casing, and a coupling member for releasably securing the stud to the casing. The central stud and two extending screws on the backplate are universally pivotable and integrally formed with the backplate. The screws are driven axially relative to the casing by motor driven rotated nuts within the casing to pivot the backplate and a supported mirror about the central stud.

Abstract: An assembly, specifically a mirror assembly for a motor vehicle, in part angularly adjustable by an electric motor and drive mechanism. A fixed motor drives a worm that is angularly movable through a flexible coupling into selective engagement with one of two nuts to drive adjusting screws that cause a mirror element to pivot about one of two mutually perpendicular axes. The screws and pivot structure for the mirror are integrally formed as part of a mirror supporting plate. The nuts are yieldably coupled to the threads of the adjusting screws to permit slippage between the two when forces exceed the wormed driving force. Operating noise is reduce by a vibration-damping motor mounting and by structure limiting worm engagement with the nuts. Projections are carried by the mirror supporting plate resiliently biased against a fixed support to reduce vibration.

Abstract: A collapsible antenna, adjustable in length and carrying an impedance-matching coil, especially suitable for use with citizens-band transceivers that are operated from automobiles. When the antenna is collapsed, the coil is concealed within an antenna support, which in automotive applications is typically located beneath a vehicle body panel.

Abstract: An adjusting means for azimuth and elevation adjustment comprising a hollow support and a universal joint connected to the support and to the part to be adjusted. A reversible electric motor is mounted in the support having a shaft, a reduction gear and an electro-magnetically controlled coupling. Planetary transmission means are provided and means whereby the shaft may optionally be coupled with each of said transmission means by a reduction gear and an electro-magnetically controlled coupling. The transmission means are capable of acting on the universal joint to bring about a rotation around two different axes.

Abstract: A support for effecting limited universal adjustment of a part, comprising a universal joint member formed of moldable vibration absorbing material and comprising an elongated body having bearing means thereon for pivotally mounting the joint on a support for pivotal movement in one plane, and having a mounting plate adjacent an end of the body for attachment to the part to be adjusted, with a flexible connection to the body, for pivotal mounting of the part to be adjusted in another plane. The support is especially useful for mounting a rear view mirror on a vehicle for adjusting movement in both a horizontal plane and a vertical plane.
