Patent number: 6765339Abstract: An infrared lamp with a closed-off enveloping tube which encloses an emission source joined with contacts for a power supply in the form of a carbon ribbon which, extending in a direction of a long axis of the enveloping tube, determines an irradiation length of the infrared lamp in the sense of a higher irradiation output. The carbon ribbon has a length which is larger than the irradiation length by a factor of at least 1.5. With a procedure for heating a material to be processed using the infrared lamp, which makes possible short processing times in connection with a simultaneous high degree of energy efficiency, the infrared lamp may be operated such that its maximum emission lies within a wavelength range from 1.8 &mgr;m to 2.9 &mgr;m, and such that its power output comes to at least 15 Watts per cm3 of the volume enclosed by the enveloping tube over the irradiation length.Type: GrantFiled: November 22, 2002Date of Patent: July 20, 2004Assignee: Heraeus Noblelight GmbHInventors: Walter Dieudonné, Joachim Scherzer, Klaus Schmitz, Siegfried Grob

Patent number: 6713945Abstract: A coolable infrared radiator element of quartz glass with at least one heating tube, which has a gas-tight current lead-through at each of its two ends. A long, stretched-out electrical heating conductor in the heating tube serves as the radiation source. At least one cooling element is provided which has at least one cooling channel for a liquid coolant. A metal reflector is provided at least in the area of the heating conductor, which reflector has at least one reflective surface. The problem is to provide an infrared radiator which can deliver high energy concentrations of >500 kW/m2 in conjunction with low radiation losses. The problem is solved in that at least one reflective surface, when seen in cross section, describes a line around a surface, where the opening for the passage of at least some of the liquid coolant is provided in the area of this surface.Type: GrantFiled: August 17, 2001Date of Patent: March 30, 2004Assignee: Heraeus Noblelight GmbHInventors: Stefan Fuchs, Friedhelm Schneider, Joachim Scherzer

Patent number: 6464918Abstract: In the production of spiral-shaped heating elements, a device winds an oblong base material onto a mandrel while forming a spiral with the base material and equips the ends of the spiral with contacts for electrical connection. The device includes a feeding device for supplying the mandrel, onto whose casing surface the base material is wound in a spiral shape, with the oblong base material. In order to carry out a method for the production of a spiral-shaped heating element made of material containing carbon fibers, the method is as follows: utilize a base material that comprises carbon fibers which have been embedded into IBM a thermoplastic embedding compound, heat the base material to a temperature at which the embedding compound softens, wind the softened base material onto the mandrel while forming the spiral, and set the spiral shape by removing the embedding compound.Type: GrantFiled: August 30, 1999Date of Patent: October 15, 2002Assignee: Heraeus Noblelight GmbHInventors: Joachim Scherzer, Siegfried Grob

Patent number: 5936333Abstract: To provide a easily manufactured high-temperature connection between a pinch-sealed end of a tubular radiator and a base, without requiring cement, the pinch-sealed end has a projecting lead (9) which is fitted into, or against, a projecting end portion (11", 12") of a terminal (11, 12) with a headed outer end (11', 12'); the lead, and the projecting portion of the terminal are securely electrically and mechanically connected within a longitudinal opening (15', 16') of the base (15, 16). This connection can be effected by forming a lateral opening (19, 19') in the base in a region of engagement, or overlap of the lead (9, 10) and the projecting portion (11", 12"), and introducing energy from one side, e.g., by laser welding, or from both sides, e.g., by spot welding, or mechanical compression of the lead (9, 10), and the extending portion (11", 12") of the terminal.Type: GrantFiled: May 28, 1997Date of Patent: August 10, 1999Assignee: Heraeus Noblelight GmbHInventor: Joachim Scherzer
