Publication number: 20060207239Abstract: Compact exhaust mixer assemblies comprising a compact mixer and a trimmable open centerbody are provided. The trimmable center body allows for adjustments of the open centerbody after manufacturing and during production testing. The trimmable open centerbody may be used to compensate for production tolerances making it possible to obtain the desired core effective area for proper engine operation. The compact mixer may be either lobed or serrated. The compact exhaust mixer assemblies have a length of about half that of conventional exhaust mixer assemblies.Type: ApplicationFiled: September 9, 2005Publication date: September 21, 2006Inventors: Morris Anderson, John Gerrard, Ron Ruiz, Robert Mitchell

Patent number: 6251843Abstract: A detergent composition which is suitable for making into bars for personal washing comprises: (a) 10 to 60% wt. of a synthetic, non-soap detergent; (b) 20 to 60% wt. of water soluble material which is neither soap nor a non-soap detergent and which has a melting point in the range 40° C. to 100° C.; and (c) 5 to 50% wt. of water insoluble material which is neither soap nor a non-soap detergent and which has a melting point in the range 40° C. to 100° C. The content of water, if any does not exceed 20% wt. of the composition and better is less than 15% wt. The materials (b) and (c) serve to give structure to the bars. The compositions can be prepared by melting together the above mentioned components at a temperature of 50-100° C., without the conventional energetic working. Desirably the molten mixture contains less than 20% wt. material, other than synthetic, non-soap detergent, which does not enter the liquid phase.Type: GrantFiled: September 28, 1999Date of Patent: June 26, 2001Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: John George Chambers, Bryan Stuart Joy, Melissa Iva Katz, John Gerrard Sheehan
