摘要： Two series connected high pressure sodium arc discharge tubes include a saturated arc tube and an unsaturated arc tube. When the saturated arc tube voltage shifts in value due to changes in operating conditions, the other unsaturated arc tube voltage does not shift to compensate for the voltage increase. Because the unsaturated arc tube voltage does not shift, the rate of voltage shift of the saturated arc tube is smaller in magnitude than otherwise would occur if both arc tubes were saturated.

摘要： A 1000 watt arc discharge arc tube assembly comprises two series connected side-by-side arc discharge tubes whose combined break down voltage in sufficient for a standard 2-5 kv starting pulse to simultaneously start both arc tubes without additional structure. A standard ballast, starter and fixture can be used with the arc tube assembly whose overall length is less than 300 millimeters. The lamps are spaced sufficiently apart to preclude detrimental heat transfer effects on one another and sufficiently close to act as a single source of light in standard fixtures normally employing lamps having a single discharge tube.

摘要： The present invention relates to a direct method to convert fine and ultra fine silicon powder from polysilicon manufacturing sources such as fluid bed and free space reactors into densified granular forms. This conversion process is effected by the use of lasers of selective wavelengths from solid state diode or optically-pumped YAG sources to locally heat, melt and densify a controlled quantity of silicon powder, and comprises the steps of distributing dry silicon powder on an inert substrate, subjecting the silicon charge to a focused laser beam to realize melted and densified granular forms, and discharging the product. When adapted to high purity silicon powder, the end use for the densified silicon granular forms is primarily as feedstock for silicon-based semiconductor and photovoltaic manufacturing industries. The process, suitably modified, is adaptable to form other silicon body shapes and components.

摘要： This invention describes methods of compacting and densifying high purity silicon powder to defined geometric forms and shapes. High purity silicon powder is first mixed with binder from a select group of binders and pressed into desired shapes in a mechanical equipment. The binder is removed either in a separate step or combined with a subsequent sintering operation. The binders and process conditions are chosen to make negligible change to the purity of the silicon in the end product. When high purity silicon powder is utilized in the process, the end use for the densified silicon compacts is primarily as feedstock for silicon-based photovoltaic manufacturing industries.

摘要： A high pressure discharge lamp formed of a polycrystalline alumina ceramic arc tube which includes a discharge zone and end tubes on each side to seal the tube, the discharge zone containing light emitting metal halides and mercury and a starting gas of argon or xenon. The end tubes have longitudinally extending openings therein. The end tubes have proximal ends adjacent the arc tube and distal ends furthermost removed from the arc tube. An electrical feed through is disposed in each of the end tubes which includes a thin metal foil section disposed between two electrically conductive lead in wire wires. One of the lead in wire wires has an electrode disposed thereon. A sealing compound seals the electrical feed through to the alumina of the end tubes at the outer ends thereof.

摘要： A fluorescent lamp having an adjustable color temperature comprising at least two elongated fluorescent discharge tubes (10 & 20), one tube (10) having a larger diameter than the other (20). The tubes (10 & 20) are assembled into a single unit. A groove (12) is disposed within the larger tube (10) and runs parallel to the longitudinal axis. The smaller diameter tube (20) is snugly nested within the groove (12) and in intimate contact with the larger diameter tube (10). The larger diameter tube has a phosphor coating producing one color temperature and the smaller diameter tube produces a different color temperature. Preferably, the larger tube has a phosphor coating that emits a low color temperature of 3000.degree. K. or below and the smaller tube's phosphor coating emits a high color temperature of greater than 10,000.degree. K. A controller divides the power to the two tubes such that a variable color temperature is produced at nearly constant total power.
