Patent DE-3941908-A1 (DE)
Title: Colour coded yarn tubes with additional markings - can be identified automatically at winding
Inventor: WEICH OTTO
IPC: B65H67/06
Filed: 1989-12-19
Abstract: The yarn tube (2) from the spinning machine has a specific physical property which can be automatically identified by a detector (3) at winding. The property correlates with the type of yarn and corresponds with the tube colour normally used to identify the yarn type. The tube is divided into sectors I to VI and at one or more positions an aluminium strip is wound into the paper tube and detected by a proximity switch (4). Alternatively the paper tube is fitted with metallic ends and a conducting material such as carbon fibre is incorporated. Different values of electrical resistance between the ends as measured by contact strips provide the identification signal. Other alternatives are signals provided by measurements of different tube lengths or the detection of various notches in the tube by a laser. ADVANTAGE - Automatic identification can give an error signal and avoid the accidental use of the wrong type of yarn at winding. The quantity of waste yarn produced is therefore reduced.

Title: Restoring ozone level in upper atmosphere - involves fitting ozone generating equipment in all high-flying aircraft
Inventor: SCHNEE DIETER
IPC: B64D1/16
Filed: 1990-10-17
Abstract: It has been proven that even with a 100 percent cessation in the prodn. of chloroflurocarbon gas such gas will still rise into the stratosphere for another 120 years, disturbing the ozone layer, and, as of now, no natural or technical solution is in sight. Up to the year 2000, it is expected that air traffic, both civil and military, will have doubled, and that from an energy-saving point of view flying heights in the stratosphere should be preferable. It is therefore proposed that ozone producing equipment should be installed in all aircraft, which would be started once the aircraft had entered the stratosphere. The thus produced ozone would be discharged into the stratosphere, and when the aircraft would re-enter the tropopause, the ozone producing equipment would be switched off. USE/ADVANTAGE - To replenish the depleted ozone layer by generating ozone in high-flying aircraft.

Title: Tool for inserting retaining rings in bores - has ring pushed into groove in inclined position by three push rods, one being spring loaded
Inventor: NAUJOKS KURT
IPC: B25B27/00
Filed: 1991-01-15
Abstract: The tool consists essentially of a magazine (6) for a stack of retaining rings (2), a ring dispensing slide (7), and three sliding push rods (9a, 9b, 9c). By way of example the retaining ring is inserted in the groove (3) to retain the gudgeon pin (5). A guide piece (8a, 8b) aligns the nose of the tool with the bore. One ring is released by actuation of the dispensing slide and the handle (10) is pushed downwards, taking the push rods with it. Because rod (9a) is in advance of the others the ring takes up an inclined position (II)( as it is moved into the bore. The end of the gudgeon pin acts as a stop and continued downward movement of the handle advances rods (9b) and (9c) relative to (9a) and seats the ring squarely int he groove. ADVANTAGE - Inclined position of ring during insertion prevents jamming. Simple and easy to use.
