Patent DE-2829006-A1 (DE)
Inventor: UHLMANN GEORG
IPC: C02F3/08
Filed: 1978-07-01
Abstract: An improvement for the aeration of the water and combining the aeration with the cleansing of the water by a biological cover, in which one or several circular disks rotate in a clarifying reservoir about a horizontal shaft. These carry at their circumference annularly bent funnels which extend in part above the water surface and continuously converge in direction from the inlet opening to the outlet opening. Above the water surface air enters through the inlet opening into the funnel and below the water surface water enters into it. Because the funnel converges continuously, both water and air are accelerated and compressed in the funnel. The compression assures that the amount of oxygen which is soluble in the water and can be accepted by the same from the air, is substantially increased. The biological cover forms on the disks and on the outer surface of the funnel.

Title: Pusher furnace scratch prevention - by glazed coatings on sliding workpiece undersides
Inventor: KNAAK RUEDIGER DIPL ING DR
IPC: F27D3/02
Filed: 1978-08-18
Abstract: A pusher-type conveyor furnace can be operated without risk of producing scratch marks by scale particles trapped between the workpieces and the supporting rails. Prior to charging the workpiece, they are given a nonmetallic coatingat certain areas, applied by spray gun or scraping trowel. The coating is produced from a glazing fluid and retains its lubricity even at high temps. This produces a heat-treated output of the same high scratchless quality as a walking beam furnace but without the complicated mechanism of the latter.

Title: Double sleeve filter unit to remove dust from gases - having rotating suction pipe with nozzles below the sleeve inlet to clean sleeves
Inventor: LUEBKE GUENTER
IPC: B01D46/48
Filed: 1978-12-04
Abstract: Filter unit consists of double wall cylindrical sleeves, the dirty gas being blown up the annular space between the two sleeves. The sleeves are firmly supported at the top and the inner sleeve has a spring mounting at the base. To clean them, a suction pipe is mounted below the inlets on a rotating flange coupling. This rotates around and subjects all the sleeves in turn to suction and thereby a reverse gas pulse. This discharges the dust and allows it to flow over to a cyclone collector. Coarse material is removed from the base. Used for removing dust from gas streams. Arrangement gives a simpler and more reliable system than shaker or reverse pulse systems.

Title: Vehicle seat belt tightening system - winds belt around drum using electromotor actuated by switch when tension drops below min.
Inventor: WYCHNANEK RAINER DIPL ING
IPC: B60R22/44
Filed: 1979-02-28
Abstract: The tightening system has an electromotor (2) connected in series with a switch (3) that operates depending on the tension in the seat belt. The motor drives the drum and may be located inside the drum or adjacent to it. The switch has a unit (6) that measures seat belt tension and operates the switch when the tension reaches a given value. The measuring unit consists of a spring-loaded guide rod (9) with two rollers between which the belt passes.
