Title: Generator to detect movement of component - converts uniform primary control signal into secondary control signal applied to drive
Inventor: HOPPE WALTER PROF DIPL CHEM DR
IPC: H02P8/14
Filed: 1977-08-18
Abstract: The component movement has a specified speed characteristic, and the device comprises a drive for the component.

Title: Combined ultrasonic and electric resistance welding appts. - for welding metals coated with oxide
Inventor: RASKE HANS-ERICH
IPC: B23K28/02
Filed: 1978-06-16
Abstract: The process uses a sonotrode subjected to ultrasonic vibration and also used to apply pressure on the workpieces being welded; and the workpieces are also exposed to an electric resistance welding current via an electrode. Welding is achieved without deformation of the workpieces, which consist of metals, or non-metals coated with metal, where one or both metals is covered by a layer of oxide, and/or the metals have very different m.pts. An example is the welding of Be-Cu either to Be-Cu or to the nickel-silver. Pref. the two workpieces are pressed against an anvil by a sonotrode, which is also fed with teh electric welding current; the second welding electrode may be replaced by anvil. The joint is first preheated by electric current and then the sonotrode is vibrated by an ultrasonic generator. Ultrasonic vibration destroys the oxide layer, and the combined process produces very strong welds.
