Patent number: 4552702Abstract: Lower alkyl esters of higher fatty acids with improved processing properties, particularly sulfonation, are obtained by subjecting lower alkyl esters of higher fatty acids of plant and/or animal origin, or said fatty acids per se, in the presence of esterification catalysts and/or carboxylic acid anhydrides, to a brief temperature treatment above 150.degree. C., and separating simultaneously and/or subsequently, preferably by distillation, the purified lower alkyl esters of higher fatty acids or the purified higher fatty acids from the treated material and the purified higher fatty acids are then esterified with lower alkanols.Type: GrantFiled: July 12, 1982Date of Patent: November 12, 1985Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Karl Schmid, Horst Baumann

Patent number: 4479555Abstract: A power tool having a plastics material housing and a power output spindle is provided with a tube-like metal member in the front end of the housing. A bearing is received within the tube-like member for supporting the spindle. The tube-like member has at the front end thereof radially outwardly extending tabs for dissipating heat therefrom. The tabs are preferably partially embedded in the plastics material of the front end of the housing for anchoring the member therein, alternate tabs preferably being angled rearwardly. The member may also support ratchet teeth of a hammer drill. A fan may be mounted on the spindle in the region of the front end of the member for facilitating dissipation of heat from the radial tabs.Type: GrantFiled: November 12, 1982Date of Patent: October 30, 1984Assignee: Black & Decker Inc.Inventors: Horst Grossmann, Rolf Meier, Karl Schmid

Patent number: 4470878Abstract: In a coking process, coal to be coked is preheated in a cascaded whirling bed drier into which the coal is charged from above and exposed to an indirect heat transfer while whirling in a coal-stream mixture. Hot gas applied to the heating pipes in respective cascades of the drier is branched off from the total amount of hot gases discharged from a dry cooler in which hot coke from the coke oven is cooled by recirculating cooler gas constituted by a partial gas stream discharged from the cascades of the drier and reunited with the other partial stream subject to a heat exchange for generating steam. Steam from the whirling beds is discharged from the cascaded drier, separated from the entrained dust particles, and then the excessive steam is drained in a branch conduit and the remaining steam is compressed and reintroduced into the lowermost whirling bed in the drier.Type: GrantFiled: February 22, 1983Date of Patent: September 11, 1984Assignee: Krupp-Koppers GmbHInventors: Vladan Petrovic, Karl Schmid, Friedrich Jokisch, Heinz Rotthaus
