Patent number: 6677264Abstract: A catalyst for purifying exhaust gases of a diesel engine. The catalyst contains two functional layers superimposed on an inert supporting body, whereby the first layer, which is situated directly on the supporting body, has a nitrogen oxide storage function and the second layer, which is in direct contact with the exhaust gas, has a catalytic function. The second functional layer additionally has a hydrocarbon-storage function and its catalytic function is provided by catalytically active noble metals of the platinum group which are deposited in highly dispersed form on finely divided, acidic carrier materials. Nitrogen oxides in the oxygen-rich exhaust gas of a diesel engine can be converted with optimal utilization of the reductive constituents contained in the exhaust gas. For this purpose, no reducing agents going beyond the reductive components (carbon monoxide and hydrocarbons) which are contained as a consequence of incomplete combustion need to be added to the exhaust gas.Type: GrantFiled: November 18, 1999Date of Patent: January 13, 2004Assignee: Degussa-Huls AktiengesellschaftInventors: Harald Klein, Wolfgang Strehlau, Egbert Lox, Thomas Kreuzer, Wilfried Müller

Patent number: 6425863Abstract: Method for monitoring insulin medication in which blood sugar values are determined before and after a meal. The difference between these measured values is plotted against a quotient calculated from the bread units ingested during the meal and the insulin units used to compensate for these bread units. Displaying many such points on a graph provides criteria for improving the insulin medication.Type: GrantFiled: February 28, 2001Date of Patent: July 30, 2002Assignee: Roche Diagnostics GmbHInventors: Karl Werner, Peter Blasberg, Wilfried Muller

Patent number: 6220022Abstract: A catalyst system for the treatment of exhaust gases from a diesel engine includes a first and a second catalyst reducing catalyst arranged in series in an exhaust gas treatment system. The first catalyst is located near the engine in a region of the exhaust gas treatment system in which the exhaust gas temperature reaches temperatures of more than 200° C. under full engine load. The second catalyst is located further from the engine in a region of the exhaust gas treatment system in which the exhaust gas temperature reaches a maximum of 500° C. under full engine load. The maximum nitrogen oxides reduction in the first catalyst takes place at a lower temperature than the maximum nitrogen oxides reduction in the second catalyst.Type: GrantFiled: August 4, 1999Date of Patent: April 24, 2001Assignee: Degussa AGInventors: Wilfried Müller, Jürgen Leyrer, Rainer Domesle, Klaus Ostgathe, Egbert Lox, Thomas Kreuzer

Patent number: 5375692Abstract: A transfer device for books, inner books, newspapers, stacks or papers or similar products that are fed to a distribution point in a product stream on a high speed conveyor which includes a rotationally driven accelerator/decelerator. The speed of the accelerator/decelerator is controlled in such a manner that the product to be distributed is first accelerated to separate it from the next succeeding product in the product stream and the product is then controllably slowed so that it may be stopped at the distribution point without damage.Type: GrantFiled: June 11, 1993Date of Patent: December 27, 1994Assignee: Kolbus GmbH & Co., KGInventors: Reimar Staudinger, Gunter Geldmeier, Wilfried Muller

Patent number: 5353506Abstract: The invention is directed to a motor-driven chain saw having a drive motor arranged in a housing. The drive motor drives a saw chain on a guide bar via a sprocket wheel. The guide bar extends forwardly in the longitudinal direction of the chain saw and has an elongated slot in its rearward end facing toward the housing. Stud bolts fixed on the housing extend through the elongated slot in a direction transverse to the longitudinal direction of the chain saw. The rearward end of the guide bar is clamped between the housing and a sprocket-wheel cover through which the stud bolts extend. A holding device separate from the sprocket-wheel cover is provided at the rearward end of the guide bar for holding the rearward end of the guide bar in its position on the housing when the sprocket-wheel cover is removed. This holding device reliably holds the guide bar for mounting the saw chain.Type: GrantFiled: December 23, 1992Date of Patent: October 11, 1994Assignee: Andreas StihlInventors: Wilfried Muller, Helmut Zimmermann

Patent number: 4867270Abstract: The invention relates to an exhaust gas muffler for a two-stroke engine of a portable handheld tool such as a chain saw. The exhaust gas muffler includes a catalyzer wherein high exhaust gas temperatures are developed because of the exothermal reaction which takes place therein. The catalyzer is located in the forward portion of a gas-tight hollow body mounted in the housing of the muffler. The hollow body has a tapered portion which extends out of the housing in the direction of the exhaust gas flow. In this way, the surface temperature of the muffler housing is reduced.Type: GrantFiled: October 17, 1988Date of Patent: September 19, 1989Assignee: Andreas StihlInventors: Michael Wissmann, Jurgen Grassmuck, Wilfried Muller, Helmut Zimmermann

Patent number: 4012136Abstract: A projecting device, particularly for use in photogrammetry, employs a Fresnel condensor for illuminating a picture carrier which is imaged through an objective, including a diaphragm, onto a projection table. At least half of the illumination rays entering said objective, is suppressed by said diaphragm. The Fresnel condensor and the severe stopping-down of the objective produce interfering chromatical effects on the projection table. Said chromatical effects are eliminated either by means of a bi- or multifocal embodiment of the Fresnel lens or by insertion of optical means which extend the optical illumination path or by a respective embodiment of the light source.Type: GrantFiled: February 5, 1975Date of Patent: March 15, 1977Assignee: Jenoptik Jena G.m.b.H.Inventors: Harald de la Croix, Wilfried Muller
