Patent number: 5478343Abstract: A targeting device for making holes in cortical bone for bone nails has a right angle drill which interconnects to a telescopic guide member. The guide member attaches to the drill at the side thereof opposite the chuck. The free end of the telescopic guide attaches to an X-ray machine and maintains the drill in position during the drilling operation. A manual targeting device is used to locate bores in the bone nail and to spot drill the bone. The aligned telescopic guide is then used to complete the drilling operation.Type: GrantFiled: July 22, 1994Date of Patent: December 26, 1995Assignee: Howmedica International, Inc.Inventor: Gebhard Ritter

Patent number: 4906415Abstract: Monocarboxylic anhydrides of the general formula (RCO).sub.2 O are made by reacting a carboxylic acid ester or dialkylether of the general formulae RCOOR and ROR, respectively, in which R stands for one and the same alkyl radical having from 1-4 carbon atoms, with carbon monoxide in gas phase, in the presence of iodine or bromine or their compounds as a reaction promoter and also in the presence of a carrier-supported catalyst containing noble metal compounds of group VIII of the Periodic System, at temperatures of 130.degree.-400.degree. C. and under pressures of 1-150 bars. To this end, a novel carrier-supported catalyst is used in which the carrier material has a noble metal/chelate-compound formed of the noble metal compound and a chelator containing organonitrogen, organophosphorus, organoarsenic or organosulfur groups applied to it.Type: GrantFiled: March 31, 1988Date of Patent: March 6, 1990Assignee: Hoechst AktiengesellschaftInventors: Gerhard Luft, Gebhard Ritter
