Patent DE-2730069-A1 (DE)
Inventor: FAHRENSCHON KURT DIPL PHYS
IPC: G09F9/00
Filed: 1977-07-02
Abstract: A chronometric indicator has a multidigit display each of whose digits is formed by a plurality of individually energizable digit segments having respective digit-segment connections and having a common digit-display connection so that simultaneous energization of the common connection with any of the digit-segment connections will optically activiate the respective digit segments. An annular array of sixty angularly equispaced analog display segments surrounds the multidigit display and has an analog-segment connection for each part and inner and outer rings subdividing the analog display segments into inner and outer parts. Simultaneous energization of the inner or outer rings and one of the analog-segment connections will optically activate the corresponding inner or outer part. Each of the digit-display connections is connected to a respective one of the analog display segments. A sequencer is connected to the rings and all of the connections and in the first part of a three-part cycle energized the outer ring and one of the analog segment connections to display the minute, in the second part it energizes the ring and one of the analog segment connections to display the hour, and in the third part energizes the common connection of the multidigit display and several of the analog segment connections to form a digital display of the second.

Title: Single phase induction motor with two windings - with auxiliary winding current controlled by PTC resistor which heats up to close open circuit
Inventor: GHOSH SHYAMAL
IPC: H02P1/44
Filed: 1978-05-12
Abstract: The auxiliary winding (3) is in series with a parallel combination of a capacitor (4) and a PTC resistor (5). The object of the circuit is to give enhanced starting performance. At starting the PTC resistor (5) has a low value, and a high current flows throug the winding thus assiting in giving a high strating torque. As the PTC resistor heats up its resistance becomes high and in effect becomes an open circuit. The motor then continues to run with a capacitor linked auxiliary winding and the main winding (2).

Patent DE-2823820-A1 (DE)
Inventor: KLEEBERG WOLFGANG DR RER NAT
IPC: C08J3/24
Filed: 1978-05-31
Abstract: The invention relates to a method for cross-linking radically cross-linkable polymers and for stabilizing such polymers against oxidative and/or thermal decomposition. The method is developed so that rapid and economical cross-linking of radically cross-linkable polymers is obtained in the presence of oxidation inhibitors without adverse effects on the cross-linking process due to the oxidation inhibitor. For this purpose, the invention provides that the cross-linking is carried out in the presence of oxidation inhibitors, wherein the inhibition-active -OH and/or -NH functions are at least partially substituted by protective silyl- and/or silylene groups, the inhibitor molecule containing at least one Si-alkenyl group. The method according to the invention is suitable for use with radical as well as radiation-cross-linkable polymer.
