Embodiment Construction

[0038] FIG. 1 shows a single-sided incandescent lamp 1 with a lamp tube 2 formed of quartz glass, a pressure wall pin 3 and an inner current lead 10 in which a foil 4 is combined with the light-emitting Body 7 is connected. The illuminator 7 is a simple helical, axially arranged wire formed of TaC, the ends 14 of which are not helical and are transverse to the lamp axis. External leads 5 are placed on the foil 4 on the outside.

[0039] The structures described here can, for example, also be applied to lamps with other metal carbide illuminants, such as hafnium carbide, zirconium carbide, niobium carbide. Alloys of different carbides can also be used. Furthermore, borides or nitrides, in particular rhenium nitride or osmium boride, can be used.

[0040] Lamps generally preferably employ luminophores formed from tantalum carbide, which preferably consist of a simple helical wire. Zirconium carbide, hafnium carbide or alloys of different carbides, such as those described in ...

Abstract

A method for heating a fluid using a heating tower. The method includes the steps of drawing an air stream into the heating tower through an inlet and passing the air stream over a series of coils. The method for heating a fluid also includes discharging the air stream from the heating tower through an outlet and isolating the inlet air stream from the outlet air stream.

Description

technical field [0001] The invention is based on an incandescent lamp according to the preamble of claim 1 having a luminous body comprising a refractory metal compound. This relates in particular to incandescent lamps having a carbide-containing luminous body, and the invention relates in particular to halogen lamps which have a luminous body made of TaC or whose luminous body contains TaC as an essential component or as a coating. Background technique [0002] A known option for increasing the efficiency of incandescent lamps is to use a filament formed from a high-melting ceramic, such as tantalum carbide. For this see, for example, Becker, Ewest: "Physical and radiation-technical properties of tantalum carbide (Die physikalischen und strahlungstechnischen Eigenschaften des Tantalkarbid)", Zeitschriftfuer technische Physik, No. 5, pp. 148-150 and No. 6, 216-220 p. (1930). The increase in efficiency follows from the fact that incandescent bodies made of metal carbides ca...
