摘要： The invention discloses an arrangement for mechanically and electrically contacting a glow wire of a thermal radiation source, comprising a glow wire made of refractory metal having at least one flat connection surface to be contacted, a contact surface on which the glow wire is contacted, and a contacting means which connects the glow wire to the contact surface. The invention also relates to a method for producing the contact according to the invention. The problem addressed by the invention, of providing a reliable and enduringly stable mechanical and electrical contact of glow wires made of refractory metals, is solved in that the flat connection surface has at least two perforations and/or at a circumferential edge of the connection surface of the glow wire at least two recesses are formed, wherein the contacting means is integrally connected to the contact surface at the location of the perforations and/or recesses and forms both an electrical and a mechanical connection to the glow wire at the location of the perforations and/or recesses by means of a flange-like design of the contacting means above the connection surface of the glow wire.

摘要： A high luminous efficiency energy-saving halogen tungsten lamp includes a bulb shell, a molybdenum bracket, a tungsten wire, molybdenum strips and molybdenum wires. The molybdenum strips, the tungsten wire and the molybdenum bracket are packaged in the bulb shell, the bulb shell is filled with circulating gas, an upper end of each molybdenum strip is respectively connected with one molybdenum wire, an upper end of each molybdenum wire extends out of the bulb shell, a lower end of a first molybdenum strips is connected with an upper end of the molybdenum bracket, a lower end of the molybdenum bracket is connected with the tungsten wire, and an upper end of the tungsten wire is connected with a second molybdenum strip. The high luminous efficiency energy-saving halogen tungsten lamp adopts a single-filament and single-end structure, the size of the bulb shell is smaller, and it has only one cold end, so that the heat loss of the glass bulb shell and a filament can be reduced, the luminous efficiency can be maximized, visible light output is much more, and the service life is also prolonged.

摘要： It has been discovered that potassium retention in NS tungsten processing may be improved by double doping tungsten blue oxide (TBO) prior to reduction. The novel `double-doping` process consists of dry doping standard singly doped K--Al--Si TBO with potassium nitrate, KNO.sub.3, followed by the standard reduction, acid washing, sintering, rolling and drawing steps. In another aspect, the novel method includes an aqueous extraction of heteropolytungstate anion [SiW.sub.11 O.sub.39 ].sup.8- from a sample of the singly doped tungsten blue oxide to predict potassium retention.

摘要： Life expectancy, through reduction of filament sag and halogen corrosion of tungsten filaments, is greatly increased for tungsten-halogen lamps by including within the filament environment a quantity of copper. The copper can be present as one of the lead-in wires; a plating on the lead-in wires; a separate copper insert; or a coating on the filament. It is believed the copper acts as an oxygen getter.

摘要： INTERMETALLIC COMPOUNDS WHICH, UPON COOLING BELOW A CHARACTERISTIC TEMPERATURE TF, ARE SUBJECTED TO A SO-CALLED MARTENSITE CRYSTAL TRANSFROMATION TO A CRYSTAL STRUCTURE HAVING A CLOSER PACKING MAY BE USED AS SHAPED MEMORY ELEMENTS. SHAPE MEMORY ELEMENTS HAVE THE PROPERTY THAT, AFTER DEFORMATION AT A TEMPERATURE BELOW TF, THEY REASSUME THEIR ORIGINAL SHAPED BY HEATING ABOVE TF.

摘要： A high temperature heater lamp including a ceramic envelope is disclosed. The ceramic envelope is substantially infrared transparent and is composed of a refractory ceramic. The heater lamp also includes two lead wires communicatively coupled via a filament. The filament is enclosed within the ceramic envelope, which is evacuated. The heater lamp may include at least two metallic IR shields within the ceramic envelope, at least one located on either side of the filament. The filament may be tungsten, a carbon filament, or molybdenum. At least one end of the ceramic envelope may be sealed with a metal cap affixed to the ceramic envelope by a high vacuum sealant. The heater lamp may be configured to operate at above 1500° C. The ceramic envelope may have a wall thickness less than 1 mm thick.
