Title: Process for the Electrostatic Coating of Workpieces
IPC: B05D7/26
Filed: 1979-06-05
Abstract: The invention relates to a process for the electrostatic coating of workpieces which are completely or partly composed of insulating material. In electrostatic coating, the coating material is applied to the workpiece in powder or other freely-flowing form, using the forces of an electrical field, and dried or melted (fused) in subsequent heat treatment. An electrostatically semi- conductively acting surface having a surface resistance of 10<9> to 10<12> ohms is produced in a workpiece to be coated. Such a surface may be provided by coating with quaternary ammonium compounds or by incorporation of quaternary ammonium compounds into the substrate. Thereafter a coating of a powdery or other free-flowing material is applied with the use of coating appliances using the principle of creating an ionized cloud of electrically charged particles of atomized coating material to effect coating of the surface of said workpiece.

Title: A driving tool powered by internal combustion
Inventor: JOCHUM PETER
IPC: B25C1/08
Filed: 1982-04-08
Abstract: This tool is used for driving fasteners, such as nails, into receiving material. Combustion pressure of propellant gases which are ignited by means of a spark plug (13) serves to propel the fasteners. The propellant gases pass, for this purpose, by way of a supply line (15) and a feed duct (16), formed through the spark plug (13), into a combustion chamber (12). The flow of propellant gases along the feed duct (16), both during the introduction of said gases and during the combustion procedure, rids those parts of the spark plug (13) which form the feed duct (16), particularly the insulator (19), of deposits of condensate or dirt. In this way the retention of high ignition qualities of the driving tool is ensured. <IMAGE>
