Title: Assembly process for base linings - uses refined steel sheets with deep-drawn upwardly tapering grooves
Inventor: SCHMIDT ULRICH
IPC: B65D90/24
Filed: 1990-06-20
Abstract: The assembly process is for base linings (a-e). It uses refined steel sheets with deep-drawn grooves in the form of lyre-shaped arcs.

Title: Tool changer gripper with spring-loaded closing mechanism - has bent hole in space under actuating plunger to allow free movement of plunger
Inventor: HANINGER RUDOLF
IPC: B23Q3/155

Patent DE-4211167-A1 (DE)
Inventor: MUELLER VOLKER DR
IPC: C21D1/09
Filed: 1992-03-31
Abstract: The invention relates to a process and apparatus for thermal surface treatment of wire rods with a metallic surface by means of an electric arc which rotates, magnetically driven, about the axis of the billet, the arc moving between an annular electrode (anode) and a billet taken through the latter and serving as cathode. According to the invention, the problem of developing improved measures for stabilizing the arc is solved, inter alia, in such a way that the rotation of the arc is achieved by means of a direct-current magnet arranged downstream of the annular electrode in the direction of running of the billet and, at the same time, the magnetic field induced by the direct-current magnet counteracts the effect of the arc root being taken along by the moving billet, and that the annular electrode current is divided into two part currents. The field of application is predominantly the thermal surface treatment of wire rod materials with a metallic surface.
