Title: Texturised core yarns of continuous filaments - having varying longitudin-ally bulk and resembling folded fancy yarns
Inventor: WATERS GRAHAM THOMAS
IPC: D02G1/02
Filed: 1972-11-13
Abstract: The parent patent, 6904702 (36718Q), describes a synthetic yarn comprising a core of fixed false-twisted filaments, and sheath component(s) of filaments in spiral form, the direction of twist of the spirals being reversed at intervals. Sheath filaments formed with a spiral direction alternating from S twist to Z twist and vice versa, can be wrapped around the core, such yarns being described as of "high degree." In this addition, texturised "low degree" yarns comprise a false-twist texturised core and a sheath consisting of false-twist texturised filament(s) with a higher crimping amplitude than those of the core, wound intermittently in spirals (which may alternately reverse their direction) to produce an integral thread with variable bulk longitudinally and periodic loops in the core. The core has a differing decitex per filament from that of the sheath and the yarns are produced by feeding the two components to feed rollers, heating zone, false-twister and drafting rollers, the latter moving relatively to the feed so that the filaments are stretched to between 1, 5 and 6, 0 times feed length, the component filaments having different stretch characteristics, with stretching taking place in the heating zone whilst they are twisted.

Patent DE-2353677-A1 (DE)
Title: Vehicle braking weight distribution - prevents rocking motion by variable length levers connecting brakes to vehicle chassis
Inventor: OSTWALD FRITZ DIPL-PHYS
IPC: B60G21/00
Filed: 1973-10-26
Abstract: The forward rocking movement when a motor vehicle is stopped leads to the redistribution of the axle loading and also the position of the bumber bars which may not meet correctly in the case of head on collision. The arrangement ensures that the vehicle maintains its normal horizontal position on braking and any kind of wheel suspension system can be used. The pressurised fluid from the brake main cylinder is displaced into the actuating chamber of the connecting lever actuator. The piston of the rocking preventing lever assembly is pushed against the force of the spring and hence the effective lever length is extended, to produce an upwards directed force against forward dipping.

Title: Testing of high voltage divider - includes determination of ratio of division by comparison with standard
Inventor: DRABENKO IWAN FEDOROWITSCH
IPC: G01R27/02
Filed: 1973-11-16
Abstract: The ratio of division of the high-voltage divider for testing is determined with the aid of a low-voltage standard voltage divider by comparing the ratio of division of the voltage divider for testing, under its operating conditions, with that of the standard voltage divider, which is chosen to be equal to the rated value of the ratio of division of the voltage divider for testing. An additional high-voltage divider is connected parallel to the voltage divider for testing and a ratio of division is set on the former, which is equal to the ratio of division of the voltage divider for testing. The standard voltage divider is then cut into the circuit of the additional voltage divider and the potential difference between the outputs of the standard voltage divider and the voltage divider for testing is measured. The value of the potential difference is used to determine the ratio of division of the voltage divider tested.
