Title: Measuring the number of turns imparted by false twisting - shrinkage determined by yarn speed being used as control
Inventor: ANAHARA MEIJI
IPC: D02G1/02
Filed: 1975-02-25
Abstract: To determine the approximate number of turns imparted to a thermoplastic yarn of synthetic fibres by false twisting as it runs under the action of heat and possibly stretching through feed rollers, a false twister, and draw rollers, the speed of the yarn under normal operating conditions is measured between the feed rollers and the false twister, and is compared with that of a yarn running under the same conditions, but without false twisting. From these figures, the actual contraction in the length of the yarn can be ascertained, and on the basis of an already determined relationship for the yarn in question, between the number of turns and the amount of shrinkage, the actual degree of false twisting can be verified. A yarn speed meter may be used to put out a signal to a comparator in which a nominal value has been registered, so that when a predetermined tolerance is exceeded, the degree of false twisting is adjusted to suit. The number of turns can be counted accurately without interruption of the operation and without any harmful effect on the yarn.

Title: Potato harvester with balanced digging cutting blades - used with variety of known riddling mechanisms
Inventor: HAGEMANN ULRICH
IPC: A01D21/02
Filed: 1975-04-10
Abstract: A potato harvester has three attachment points at the front, for the tractor. The earth is dug, and weeds cut down, by a balanced pair of blades, which move sideways in and out on their crank-driven arms and cross at the centre (5) like shears underneath the plant row. With this balanced design, it is no longer necessary for the riddle to shake sideways to compensate for the sideways swing of the cutter. This makes possible the use of other riddling mechanisms. The endless chain riddle is used in conjunction with earth-loosening rods attached to the digging blades, which vibrate sideways with them in balanced pairs.
Patent DE-2530513-A1 (DE)
Title: Plastic trim strip for car - with embedded wires to clip to securing catches internally or externally
Inventor: FRITSCH WALTER
IPC: F16B5/12
Filed: 1975-07-09
Abstract: The profiled plastic foam strip (11) which forms the main body of the trim strip, is fitted with two parallel wires (30) embedded in its underside. The wires are at the top edges of ribs formed by grooves cut on either side. They form gripping points for the ratchet shaped securing clips (40) which clip onto the strip with one end and onto the car (50) with the other end. The system eliminates the need for an accurately shaped securing bar moulded to the strip, with its inherent drawback of foam peeling off the strip. The securing catch is double headed and pulls the strip against the car, so that sealing lips (14) press the strip securely against the car.
