Filed: 1988-10-17
Abstract: The profiled cylinder (38) seated in an insertion opening (87) of the lock housing (7) is guided by a retaining bracket (93) and fixed centrally by a detent pin (121) on the retaining bracket (93). The detent pin (121) is guided displaceably on a slide piece (103) and initially stressed by a spring (131) towards the profiled cylinder (38). The profiled cylinder (38) contains a reading device for en electronic key, which device is connected through a plug-in connection (89) with an electronic circuit of the lock. The plug-in connection (89) and the detent pin (121) are so adapted to one another that the detent pin (121) firstly fixes the profiled cylinder (38) on the pedestal (93) before the slide piece (103) guided in centered manner in relation to the pedestal (93) closes the plug-in connection (89). In this way defects of alignment of the plug-in connection (89) and damage to its contact elements (107, 109 ) are avoided.

Title: Method for preventing sintering of drainages and apparatus for carrying out the method
Inventor: DEUS ULRICH
IPC: C02F1/48
Filed: 1988-12-23
Abstract: The invention relates to a method for preventing sintering of drainages and an apparatus for carrying out the method. Drainage water is taken off from the drainage and conducted through a field magnet in such a way that as a result of the field magnet oscillations the calcium carbonate crystals are formed in a manner preventing deposition. The drainage water thus treated is then returned to the drainage as flushing water upstream from the water take-off position and flows back in the drainage to the water take-off position.

Title: Multistation winder - cuts yarns to full bobbins simultaneously to give identical bobbins from each station
Inventor: DAMMANN PETER DIPL ING
IPC: B65H54/71
Filed: 1989-06-19
Abstract: When changing the bobbins at a multi-station winder, to give identical bobbins from each station which behave the same way, e.g. in dyeing, on interrupting the winding action all the yarns are led to a waste unit at each winding station and cut simultaneously between the catch points and the winding bobbins. The rotary speed of the bobbin sleeves and the yarn feed speed are reduced to inching levels. The full bobbin is doffed at each station and replaced by an empty sleeve, and the yarn is passed to each empty sleeve to form a reserve winding, as one leg of a loop formed by the waste yarn and length between the sleeve and the waste unit is cut, or the waste yarn is passed to a transfer unit which forms a yarn loop to be cut between the waste and transfer units and laid as a yarn reserve round the sleeve and again cut between the empty sleeve and the transfer unit. When all the yarns have been laid, the speeds of the rotating sleeves and the yarn feeds are returned to operating levels and the yarn reserve units are brought out of action in a sychronised operation. The yarns return to their reciprocating guides through the draw tension applied to them, to be caught automatically and directed along the sleeve lengths. ADVANTAGE - Operation gives a simple and trouble-free method to provide identical wound bobbins from winding stations.

Patent DE-4016513-A1 (DE)
Inventor: ADELMANN WALDEMAR
IPC: B01D5/00
Filed: 1990-05-22
Abstract: To separate a mixture of two gaseous components having different boiling temperatures, it is proposed that the mixture is first compressed and is then cooled to such an extent that its temperature is below the boiling temperature of the gas component to be removed. The gas component to be removed will then condense out and can be recycled, without polluting the environment. It is further proposed to pass the gas mixture, after the condensation process, over activated charcoal filters (4, 5) in order to bind remaining portions of the gas component to be removed. Return of part of the gas mixture, after passing the activated charcoal filter, for renewed liquefaction is also envisaged. The invention simultaneously proposes an expedient apparatus for carrying out this process.
