Title: Method for protection of an invertor
Inventor: NESTLER JOHANNES DR ING
IPC: H02M3/315
Filed: 1982-06-11
Abstract: In a method for protection of the thyristors of an invertor against excess current in the event of a defect in invertor synchronisation, freewheeling diodes being connected in opposite senses in parallel with the thyristors, the object is to protect the thyristors of the invertor against excess current in the event of a defect in invertor synchronisation, operation being interrupted neither by the triggering of fuses nor by the operation of a switch. This is achieved in that existing smoothing capacitors (4, 5) or capacitors which are inserted in parallel with the invertor input are supplemented by inductors (6, 7) to form a series tuned circuit which acts as an extinguishing path for the invertor in the case of the invertor pulling out. <IMAGE>

Title: Measurement method for detecting metallic objects, and metal detector for carrying out the method
Inventor: AICHELE GERD
IPC: G01V3/11
Filed: 1982-07-30
Abstract: The invention relates to a measurement method and a metal detector for detecting metallic objects, in which according to the invention the magnetic field used for the measurement is an alternating magnetic field which is received in a resonance circuit tuned to the frequency of this alternating field. If the transmitted measurement signal is influenced by metallic objects, there is a phase shift in the received measurement signal, by comparison with the transmitted measurement signal, which is measured in a circuit arrangement. A display characterising the respective metal is produced as a function of the measured phase shift. It is possible in this way to distinguish a specific metal or a specific group of metals from other metals and to detect them in an entirely pinpointed fashion.

Title: Process for removing excess metal ions from acidic chloride-containing electroplating baths
Inventor: KUEBLER EBERHARD
IPC: C25D21/18
Filed: 1983-03-24
Abstract: In a process for removing excess metal ions from acidic chloride-containing electroplating baths, that is to say, in particular, from zinc and nickel baths, part of the electrolyte is fed into the cathode space of an electrolysis cell in which the cathode space is separated from the anode space by a cation exchanger membrane. The anode space of the cell is filled with dilute acid containing an anion which does not attack the anode, for example 0.1 N sulphuric acid (pH = 1). During electrolysis, metal is deposited on the cathode and oxygen is liberated at the anode; the harmful attack of chlorine on the anode is suppressed. At the same time, the pH in the cathode space decreases. The catholyte, which is depleted in metal ions, can be returned to the electroplating bath.

Patent DE-3347794-A1 (DE)
Title: Clamping device for toothed workpieces
Inventor: BERGER GUENTER
IPC: B23B31/02
Filed: 1983-09-28
Abstract: Three toothing sections (18, 26, 26') are formed on a basic body (12), and two annular clamping bodies (30, 30') are rotatably mounted between these toothing sections (18, 26, 26') in such a way as to be essentially free of play and thus protected from contamination. The clamping bodies (30, 30') have teeth (32) which in a rest position are in alignment with one tooth each of the toothing sections (18, 26, 26') and by rotation of the clamping bodies (30, 30') can be clamped against tooth systems of two workpieces (W, W') pushed onto the toothing sections (18, 26, 26'). Mounted in the basic body (12) are two drive bodies (40, 40') which can be adjusted by means of a common actuating member (44) and have radial projections (38, 38') which are guided in helical grooves (36, 36') of the basic body (12) and engage in axially parallel grooves (34, 34') of the clamping bodies (30, 30'). If an axial force is exerted on the drive bodies (40, 40') by the actuating member (44), the drive bodies (40, 40') perform a screw motion which results in rotation of the clamping bodies (30, 30'). The tooth systems of the workpieces (W, W') can thereby be restrained between the toothing sections (18, 26 or 26') and the teeth (32, 32') of the clamping bodies (30, 30'), as a result of which the workpieces (W, W') are centred and clamped in place on the clamping device. <IMAGE>
