Title: Carbon or graphite arc-furnace electrode burn up redn - by passing pressurized hydrogen through axial bore of porous electrode
Inventor: ERNST HANS DIPL ING
IPC: H05B7/085
Filed: 1973-06-23
Abstract: The burn-up loss of carbon and graphite electrodes, used in electric arc furnaces, is reduced by designing the porous electrode strand with a through bore parallel to the centre line. A gas pref. H2 which is inert relative to carbon, is passed into the bore at a rate adequate to protect the outer electrode surface against O2 and other oxidising gases. The system is not limited to the temp. range 1800 degrees C. Electrodes are protected over their full length, independent of their quality.
Patent DE-2338783-A1 (DE)
Title: Cassette DC motor current and voltage regulator - has regulating threshold transistor between voltage supply and motor
Inventor: GASTEIGER HERBERT
IPC: H02P7/288
Filed: 1973-07-31
Abstract: The two motors in the cassette reproducing unit have on-off switches and a slow-fast switch for rewinding. For slow speed a transistor receives a lower than normal voltage. For high speeds the voltage drop on the emitter resistance is compared with a reference voltage to produce a current limiter. The generator voltage produced on the pulled motor during rewinding controls the transistor so that its base depends on the voltage. Zener diodes produce threshold and reference voltages. A second transistor is slowly brought into use when the generator voltage increases and reduces the base-emitter voltage of the first transistor.

Title: Optical sensor for orientation of known shapes - compares scan determination of inertial axes with reference value
Inventor: SCHIEF ALFRED DIPL ING DR ING
IPC: G06V10/42
Filed: 1975-07-16
Abstract: An optical sensor for the recognition of the position and orientation of objects of known shape, is especially for use in "intelligent" robots for use in production and handling lines. During scanning the coordinates of the centre of gravity of the area enclosed by the outline of the object, the surface area, and the moments of inertia about the direction of scan and a normal to it are determined, after which the principal moment of inertial of the surface and the direction of the principal inertial axis are calculated. The sensor evaluation system has a model of the shape of the object in a memory so that there is knowledge of the area and directions of the inertial axis relative to fixed coordinates which can be compared with the measured values to determine the orientation of the sample at the time of the scan.
