Patent DE-2614343-A1 (DE)
Title: Cone winder for textured, esp. air textured yarns - has rotating disk reserving and paying out yarn alternately
Inventor: HEYNER HARALD
IPC: B65H59/00
Filed: 1976-04-01
Abstract: When yarn is wound on to a conical spool at a constant delivery speed by way of a traversing yarn guide, as the yarn passes the median dia. of the cone on its way to the smallest dia. and back to the middle of the cone, its path across the stretch between the yarn feeder and the traversing guide is diverted transversely. The extra distance the yarn has to travel corresponds to the conicity of the spool and as the yarn guide moves from the middle of the cone towards the largest dia. and back to the median dia. the diversion is eliminated. In the zone between the yarn feeder and the traversing guide, a disc is arranged between two fixed guides. During the double stroke of the traversing guide, the disc turns through 180 degrees along or close to the straight line connecting the two fixed guides, carrying two diametrically opposite guide rollers which are brought into contact with the yarn; the disc being arranged so that as the traversing guide moves from the median towards the smallest dia. a guide roller is brought into contact with the yarn, and is held in contact during the double stroke. When the yarn is drawn off overend, each winding comes off at constant tension without catching on the layer beneath, so that the bulking and intertwining of the filaments are not prejudiced. The invention ensures that cone is wound at uniform tension without insupportably expensive equipment. The excess yarn being fed whilst the smaller diameters are being wound is paid out whilst the larger diameters are wound so that tension remains near enough constant.

Title: Aerator for biological sewage treatment - directing water jet across air exit pores for fine bubble distribution
Inventor: WILCKE THEODOR
IPC: B01F27/94
Filed: 1976-04-27
Abstract: An aerator for use in activated sludge tanks of biological sewage treatment produces air bubbles by an element with fine pores at the submerged outlet of compressed air pipe. To achieve a certain water velocity across the air exit plane, a slotted nozle produces a tangential water jet or the exit plane is moved mechanically relative to the water. The aerator consists of a tube which is connected to a blower and terminates in a discharge element with fine pores. The bubbles leaving the pores are torn away by a water jet before they can grow. A preferred method of producing this jet is by a slotted nozzle which is directed tangentially against the element. This results in bubbles of much smaller dia. so that the better ratio of contact are to volume ensures a higher oxygen diffusion efficiency.
