Title: Multi-character yarn texturizing process - uses yarn of at least 20 filaments with overfeed through heating and pneumatic texturizing zones
Inventor: HANSEN KAI SIKEBORG
IPC: D02G1/16
Filed: 1975-08-16
Abstract: A process and apparatus are claimed for the texturizing of multi-grade yarns, where at lest one component is a filament yarn. with the yarn of processing being composed of at least 20 threads. The yarn passes through a heat treatment zone to bring it to a softening temperature, followed by rapid cooling and then texturizing by exposure to compressed air of at least 7 atmospheres. The passage of the yarn into the heat and texturizing zones is at a higher speed than the rate at which the texturized yarn is drawn out. The process increases the bulk and density of the texturized yarn reducing the amount of yarn needed for working into a fabric of a given weight.

Title: Rectifier diode mounting for multiphase supply - employing diodes of common polarity for easy assembly and replacement (CS280177)
Inventor: MALCHER JAROMIR DIPL ING
IPC: H02K11/04
Filed: 1976-09-06
Abstract: The application is typically to motor vehicle three-phase generators. The output leads (f1, f2, f3) of the generator (G) are taken to separate terminals (N1, N2, N3) which form the bases for diodes, (D1, D2, D3; D12, D21, D31) comprising, typically, the positive pole of the d.c. output. Where two sets of diodes are used these may be connected to separate supply lines (S1, S2). The d.c. negative terminal is common for the three phases and carries the appropriate diodes, (D4, D5, D6) whose cathodes are joined to the corresponding machine terminals (N1, N2, N3). The arrangement thus employs only one diode type, for example anode base, and, in a practical application, also permits a low space design as well has a saving on stock component costs and simplifying assembly and replacement.

Title: Light barrier operation monitoring in tape recorder - involves testing of phototransistor output signal by reducing light source power
Inventor: KEGLER ERNST
IPC: G11B15/08
Filed: 1976-09-29
Abstract: The system consists of a light source and a photoreceiver with threshold behaviour. The monitoring device gives a warning of accumulation of dirt, ageing and failure. Radiated power of a light source is reduced during a specified testing period to a certain value, and the output signal of the corresponding photoreceiver is checked for whether it remains at its nominal level corresponding to its normal operation, or appreciably drops owing to the illumination falling below its threshold. A test is made to find whether the low output signal regains its nominal value when the light source radiated power is restored to normal. Two LEDs (1, 2) may be used, with corresponding phototransistors (4, 5).
