Publication number: 20030039597Abstract: The present invention relates to an article comprising a catalyst composition and a method useful for the removal of NOx and SOx contaminants from a gaseous stream, especially gaseous streams containing sulfur oxide contaminants. More specifically, the present invention is concerned with catalysts of the type generally referred to as “close coupled catalysts” which are designed to reduce pollutants in engine exhaust emissions during engine cold start conditions. The article comprises a lean burn gasoline engine having an exhaust outlet, an upstream section having a close coupled catalyst composite in communication with the exhaust outlet, and a downstream section. The upstream close coupled catalyst composite comprises a first support; a first platinum group component; and a SOx sorbent component selected from the group consisting of oxides and mixed oxides of barium, lanthanum, magnesium, manganese, neodymium, praseodymium, and strontium.Type: ApplicationFiled: August 24, 2001Publication date: February 27, 2003Applicant: ENGELHARD CORPORATIONInventors: Michel Deeba, John K.

Patent number: 6497848Abstract: A catalytic trap (10, 110) effective for conversion of NOx in an exhaust gas stream is inert to high-temperature reaction with basic oxygenated compounds of lithium, sodium or potassium. The catalytic trap may be substantially free of silica components and may include a catalytic trap material (20, 120) which contains a refractory metal oxide support, e.g., alumina, having dispersed thereon a catalytic component, such as a platinum group metal catalytic component, and a NOx sorbent comprised of one or more of the basic oxygenated compounds. The catalytic trap material is coated onto a suitable carrier member (12, 112), such as one made from stainless steel, titanium, alumina, titania, zirconia or silica-leached cordierite.Type: GrantFiled: August 22, 2000Date of Patent: December 24, 2002Assignee: Engelhard CorporationInventors: Michel Deeba, Uwe Dahle, Stefan Brandt, John K.

Patent number: 5251405Abstract: A method serves for circumferential grinding of radially non-circular workpieces, in particular for grinding cams (15) or polygons. The workpiece is rotated about a first second axis (13) extending at an angle, preferably of 90.degree., relative to the first axis (18). Starting out from a raw contour, the material at the surface of the workpiece (15) is removed along spiral-shaped paths of a point of action (20), by a plurality of steps corresponding each to one rotation of the workpiece, until intermediate contours and finally a finished contour are obtained, this being achieved by rotating and/or advancing the workpiece and the grinding wheel (11) in a controlled way, in response to data records. Every time an intermediate contour is reached, a new data record is called up for the next rotation of the workpiece. One measures continuously a predetermined absolute dimension (R.sub.Gist) of the workpiece and derives therefrom the existing deviation (.increment.R.sub.G) from a given setpoint value (R.sub.Type: GrantFiled: July 24, 1991Date of Patent: October 12, 1993Assignee: Fortuna-Werke Maschinenfabrik GmbHInventors: Siegbert Clauss, Peter Meusburger, Stefan Brandt, Roland Schmitz, Gerhard Walz
