Patent DE-2341900-A1 (DE)
Title: Termination for high-current multi-conductor/strand cable - low-loss connection by use of reinforced holes for increased volumetric density of inserted conductor-strands
Inventor: DUNG HERBERT
IPC: H01B9/00
Filed: 1973-08-18
Abstract: The cable head termination of copper or suitable metal into which the stranded conductors are inserted has a cylindric connecting part to the cable. The connecting part has over the periphery distributed drillings in axial direction the cross-sections of which are reduced by reinforcing seams in axial direction. The inserted ends of the conductor strands are thus compressed to a volumetric efficiency of nearly one. For a water-colled cable the termination has a central bore and on its periphery it carries in axial direction on the jacket between each two adjacent drillings bedlike grooves which end into channels leading to the central bore. The central bore may have a pressure regulating valve at the cable side end. The cable termination may have an annular tee-slot for fixing the insulating and/or coolant hose. The cable termination secures a temperature independent, reliable and tension-proof connection to the cable resulting in no voltage-drop.

Title: Electronic circuit for a stenotype - guides the recording system in a stenotype with a position pickup having screening segment
Inventor: JOPPICH MANFRED
IPC: G01R13/40
Filed: 1974-04-04
Abstract: This segment is connected with the recording system shaft. Phototransistors are illuminated through it by light emitting diodes, in order to apply opposite sense signals to a differential amplifier. These signals are subsequently compared in a comparator with input signals to the recording system. To compensate differential amplifier output signals variations due to temperature changes, a summary amplifier is connected through resistors to the differential amplifier output resistor. Its output is connected through a transistor collector to a series circuit consisting of the l.e.d.'s and their voltage source, so that the sum signal is kept constant by the l.e.d. current control. The l.e.d. material is gallium arsenide, and of phototransistors a silicon compound.
