Abstract: The open end of a cylindrical or dome shaped cover closed at the other end fits snugly within the raised outer rim of a flat base formed of a heat transmitting material such as metal. A holder structure, preferably of lightweight metal supportable on the base to be enclosed within the cover, has one or more lightweight plates that are the approximate size and shape of a standard tortilla disposed in a roughly horizontal attitude one above the other. The base beneath the plates has concentric shallow liquid retaining areas to hold small amounts of water that can be heated and turned to steam to warm the tortillas and keep them pliant. Heat insulating handles on the cover and base permit the entire assembly to be placed over the heating element on a stove.

Abstract: A decorative light and method of manufacture thereof, said light having an outer transparent tube, a pair of electrical supply wires in the tube, and a plurality of miniature lamps within the tube, the lamps being connected in series between the supply wires, and a protective dielectric material within the tube which coats the supply wires and the lamps forming a protective dielectric cushioning layer between said wires and lamps and the walls of the tube to prevent electrical failure of the decorative light tube circuit as a result of moisture, shock and vibration.

Abstract: Pools and spas formed with lamp house accommodating wall conformations below normal water level are fitted with a flexible tubing lamp house containing special lamps having a safety conductor ending unconnected in the interior of the lamp envelope. The lamp energizing circuits and a grounding circuit connected to the safety conductors of the lamps are disposed in the lamp house with a water insoluable, light transmitting electrical insulating material which serves to insulate the circuits and exclude water.

Abstract: Decorative light tubing, which has unbased miniature lamps connected in series by soldering or welding the ends of the flexible wire leads together to form parallel strings between a pair of elongated parallel wire conductors, is substantially filled with mineral oil or other clear, viscous dielectric fluid to protect the lamps and wiring against the adverse effects of vibration, shock and moisture while also enhancing the visual effect.

Abstract: The flexible wire leads of several unbased miniature lamps are welded or soldered end to end in series to form a lamp string that has one end electrically connected to a rigid center wire extending upwardly from the center foot terminal of a lamp base so that, with the base fitted on a spherical or other rounded transparent bulb, the lamp string connection to the rigid wire will be near the central longitudinal axis at the opposite end of the bulb. With the other end of the lamp string held stationary, the base is twisted within the bulb to expand the lamp string, which is folded in a flat S-shape to fit through the narrow tubular base opening in the bulb, until the lamps are each positioned within the bulb at locations displaced from the central axis and inner concave reflecting surfaces. This insures myriad reflected lamp images that give the visual impression of many more lamps with greater apparent illumination though requiring only a few watts of energy.
