摘要： A arc discharge headlamp system (10) is disclosed. An arc discharge headlamp system (10) may be formed with a lamp housing (22) including an enclosed reflector (24), a double ended arc discharge lamp (16) having a two leads at offset ends, enclosed in the reflector. A first lamp support (18) for the front end of the lamp is coupled to the lamp housing, and a first lead connection (38) for the lamp is coupled through a high potential conductor (28) embedded in the lamp housing (22). The high potential conductor (28) embedded in the lamp housing extends subsurface to a ballast cavity (30) formed in the lamp housing and enclosing a ballast (34). The ballast (34) is potted in the cavity (30) to protect it. A second lamp lead (42) extends through a second lamp support (20) to the rear of the lamp housing to be connected to the ballast (34). The lamp capsule, high potential leads, and ballast are all securely enclosed as a single unit with potential leakage between elements, and with the outside prevented.

摘要： A metal halide arc discharge lamp comprises an arc tube containing a chemical fill including mercury and metal halides and having first and second electrodes respectively sealed at opposite ends thereof. An outer envelope surrounds the arc tube and has first and second terminals for electrical connection thereto. A source of ultraviolet radiation is provided within the outer envelope proximate the arc tube for producing radiation which illuminates the path between the electrodes of the arc tube to decrease the amount of time for generating a gaseous discharge therebetween. The ultraviolet light source includes an envelope of ultraviolet light transmitting material containing a fill material and having a single electrode sealed in one end thereof. The single electrode is electrically coupled to one electrode of the arc tube. A portion of the envelope of the ultraviolet light source is capacitively coupled to the other electrode of the arc tube such that the source produces ultraviolet radiation during lamp starting when the first and second terminals of the lamp are energized.

摘要： A process is disclosed for producing fine powder, which comprises entraining a starting powder material in a carrier gas, injecting the starting powder material using the carrier gas into a high temperature jet to form a high velocity stream of molten droplets, fragmenting the resulting high velocity molten droplets by impacting against a substrate wherein the temperature of the substrate is above the melting point of the powder material, to form smaller droplets, and allowing the resulting fragmented smaller droplets to spheroidize and solidify in flight.

摘要： A method of yielding selectively a desired enrichment in a specific isotope includes the steps of inputting into a spinning chamber (4) a gas from which the specific isotope is to be isolated, radiating the gas with frequencies characteristic of the absorption of a particular isotope of the atomic or molecular gas, thereby inducing a photoionization reaction of the desired isotope, and collecting the specific isotope ion by suitable ion collection means (28).

摘要： A method of constructing a filament support member from a single-piece preformed refractory metal wire (12) having at least one loop protrusion (20) formed in the wire and positioned between the ends of the wire. A section of glass tubing (22) is positioned over and supported by the loop protrusion (20) with a head portion (19) of the loop extending beyond the section of tubing (22). Heat (21) is applied to melt the section of tubing to form an insulating bead (23) at the base of said loop protrusion (20). The head portion (19) of the loop protrusion is then trimmed to interrupt electrical continuity in the wire (12) and thus electrically isolate the respective ends of the wire (14,16).

摘要： An improved fluorescent lamp (1) is disclosed. The lamp of the present invention includes an envelope (2) containing an ionizable medium including mercury and having electrodes (3) located within the envelope; an aluminum oxide reflector layer on the inner surface of the envelope, and a phosphor layer (4) disposed on the reflector layer. The aluminum oxide reflector layer comprises particles of high purity aluminum oxide having an average particle size greater than 0.5 micrometer and less than or equal to about 1 micrometer and having a surface area of about 4 to 6 meter²/gram. The aluminum oxide reflector layer preferably includes at least 95 weight percent alpha-alumina. Preferred coating weights for the reflector layer are from about 8.8 to about 11.1 milligrams/square centimeter.
