Abstract: An article of jewelry comprising a body having two plate members which sandwich a battery between them and having lighting elements electrically connected between the plate members to be illuminated by the battery. A circuit element in the form of a removable microchip and carrier is attachable to one of the plate members providing a means to control the characteristics of the illumination. The construction of the article renders it susceptible to easier assembly whether by manual or automatic means.

Abstract: An article of jewelry includes at least one electrically activated light source, at least two elongated and stiff electrical conductors connected to and extending from the light source, and an attachment assembly for attaching the article of jewelry to a wearer. The electrical conductors conduct electrical power to the light source and are spaced apart to provide an aperture for detachably receiving and retaining an electrical power source between the conductors with at least one conductor contacting the positive terminal and at least one conductor contacting the negative terminal of the electrical power source. The conductors frictionally retain the power source in the aperture. The conductors, aperture, light source, and electrical power source are the visible article of jewelry when the article of jewelry is being worn. The article of jewelry may be worn with or without the electrical power source.

Abstract: A cartridge type radio transceiver for citizen band radio reception and transmission, adapted for free standing use at any location, and use as a cartridge inserted into a conventional cartridge tape deck. The transceiver cartridge includes a transmitter and receiver which may be of conventional design, housed in a housing which comprises two parts, a first part insertable into the tape deck, and the other part extending forwardly of the tape deck. Microphone-loud speaker means are provided, and means for an attachment of a radio antenna. Contact means are provided for contacting conventional contact means inside of a cartridge tape player, to provide power for powering the transceiver and including magnetic transducer means for inducing receiver audio output signals into the magnetic head means of the tape deck so that said signals can be amplified and played out through the speaker means attached to the tape deck.
