Publication number: 20040216715Abstract: In an internal combustion engine having direct injection and spark ignition, charging air is introduced in stratified charge operation through one of two valve-controlled intake channels into a cylinder having a roof-like cylinder head end and a piston having a piston head with a recess oriented toward the intake side. The charging air is introduced forms a swirl flow, into which fuel is introduced. To avoid fuel accumulation on the recess wall, a strong swirl flow with a compact swirl core is achieved through a flow-optimized filling channel, with the swirl core being held in a fixed position in a rotor recess at the latest in the second section of the stroke of the piston toward top dead center such that fuel introduced into the swirl core with a relatively late end of the injection is supplied to an ignition device due to the piston movement toward top dead center.Type: ApplicationFiled: June 4, 2004Publication date: November 4, 2004Applicant: Baverische Motoren Werke.Inventors: Klaus Schmitz, Stephan Rubbert, Martin Berckmueller

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: 5276763Abstract: In infrared radiators whose heater is disposed in an envelope tube of transparent or opaque fused vitreous silica, radiation losses can be reduced by a reflective coating, for example of gold, placed on the envelope tube. To improve the thermal stability of the reflective coating, a protective coating of zirconium, silicon and/or tin dioxide is proposed. The protective coating can be made by using thermally degradable organic zirconium, silicon and/or tin compounds.Type: GrantFiled: September 22, 1992Date of Patent: January 4, 1994Assignee: Heraeus Quarzglas GmbHInventors: Wolfgang Gobel, Klaus Schmitz, Wolfgang Wild

Patent number: 5220774Abstract: The invention is directed to a cutting filament for a vegetation cutter. The vegetation cutter includes a drive motor which sets the cutting filament in motion thereby producing noise. The cutting filament extends substantially radially outwardly because of the centrifugal force. The cutting filament reduces noise especially at high rotational speeds and thus also at high peripheral speeds. This is achieved in that the cutting filament is configured to have a cross section not having point symmetry. The cutting filament preferably has at least one slot and/or protrusion formed in the surface thereof to extend in the longitudinal direction. The slot and/or protrusion can, for example, be formed so as to follow a helical path with respect to the longitudinal axis of the filament or it can extend parallel to this axis.Type: GrantFiled: February 22, 1991Date of Patent: June 22, 1993Assignee: Andreas StihlInventors: Jorg Harbeke, Klaus Schmitz

Patent number: 4658392Abstract: An optically readable, high storage density information carrier usually in the form of a disk, for example, a digitally recorded audio disk (CD) or a video disk (VLP) including a base, and a microstructure on the base which contains the recorded information, and consists of spiral or annular tracks or channels on one or both sides thereof. A reflective layer of a suitable metal or alloy is applied to the side of the information disk carrying the microstructure in at least that portion in which the microstructure exists. The present invention provides an improved reflective layer which, in turn, is covered by a protective layer. The improved reflective layer is a metal alloy selected from one of the following groups of alloys: (1) a Cu-Cr alloy containing from 0.3 to 1.5% chromium, (2) an Al-Mg-Si alloy containing 0.5 to 1.5% each of magnesium and silicon, and (3) an Mg-Mn-Si alloy containing 1.2 to 2% manganese and 0.05 to 0.1% silicon.Type: GrantFiled: April 26, 1985Date of Patent: April 14, 1987Assignee: Polygram GmbHInventors: Horst-Christian Langowski, Klaus Schmitz
