Patent DE-19754175-A1 (DE)
Inventor: BOENISCH HELMUT DR
IPC: C02F3/22
Filed: 1997-12-06
Abstract: The invention relates to a device for intensive biological waste-water treatment with freely moveable immersed biofilm, combined with mixing devices and, optionally, the introduction of air. The freely moveable immersed biofilm is used to immobilize specific micro-organisms in certain areas for waste-water treatment. In comparison with previously known devices, the invention is characterized in that the clarification process is more intensive due to the additional freely moveable, suspended/ floating immersed biofilm and its proportional oxygen supply from a special mixing device, provided upon emergence into the atmosphere in addition to aeration from fine bubbles. A substantially greater utilization of oxygen is obtained by enriching the air of the recycled sludge or waste-water through multiphase pumps. According to the invention, the activated sludge process is combined with the freely moveable immersed biofilm process in an installation. Said freely moveable biofilm is introduced into a sewage-treatment basin (1) as a biofilm carrier with an activated surface to immobilize specific micro-organisms in association with appropriate mixing devices (7) having a scooping effect due to paddles (3) and the proportion of activated sludge (6). Waste-water (4) flows through the sewage treatment basin (1) which comprises a retaining device (5) for the freely moveable immersed biofilm (2).

Title: Natural stone paving production details
Inventor: SCHWEIKERT OTFRIED
IPC: B28B19/00
Filed: 1998-01-16
Abstract: The paving stones (1) are laid fixing side foremost into a finishing form (8) on plate (9) and arranged in adjacency.   The placing pattern is optional and the completed layer of stones is finalized by a filler (6) first in slurry form into the stone joints and then filled right to the back of the form using reinforcing bars (5). This gives a level surface for topping off by a plate (9) prior to tensioning to the bottom plate (9) etc.   Filling is by concrete, sand and cement mix, bitumen, plastics or mixtures of these, the joints being poured prior to the facing or filling operation.   The bars serve to stabilize the filler.

Patent DE-19821305-A1 (DE)
Title: Niveauregeleinrichtung
Inventor: KLEEN BEREND
IPC: B60G17/052
Filed: 1998-05-13
Abstract: Es wird eine Niveauregeleinrichtung zur Regelung des Abstands-Niveaus zwischen den Fahrzeugachsen und dem Fahrzeugrahmen eines Fahrzeuges vorgeschlagen. Die Federung ist als Voll- bzw. Teilluftfederung ausgeführt, wobei sich der Fahrzeugrahmen über den Fahrzeugachsen über Luftfederbälge abstützt. Aufgrund sehr unterschiedlicher Situationen kann es zu einem Schiefstand, einer nicht parallelen Ausrichtung zwischen Fahrzeugrahmen und Fahrzeugachsen kommen; einen einfachen Grund stellen z. B. Unebenheiten dar, wenn beispielsweise ein Rad einer Fahrzeugachse auf dem Bordstein steht. Um Luftverluste zu vermeiden wird darauf verzichtet, einen Schiefstand bei stehendem Fahrzeug auszuregeln; statt dessen wird der vorliegende Schiefstand beibehalten und dem Regler als Soll-Niveau vorgegeben. Mit dieser Sollwertvorgabe werden alle Niveauänderungen, die sich aufgrund von Änderungen in der Beladung des Fahrzeugs einstellen, ausgeregelt. Bei einem späteren Übergang in den Fahrbetrieb müssen die Drücke in den Luftfederbälgen - wenn überhaupt - nur geringfügig verändert werden, was den Luftbedarf ebenfalls verringert.

Title: Hydrodynamically operated retarder suitable for co-operation with anti-lock braking system
Inventor: BAILLY GERHARD
IPC: B60T1/087
Filed: 1998-06-20
Abstract: The common version of a retarder, normally used as a permanent braking device to be used for instance while driving along long sloping stretches in a mountainous area, was not designed to perform a quick reaction. When used in combination with the brake system of the vehicle, the time needed for reacting has to be reduced. All units (housing, rotor, stator, reservoir) of the new design of a retarder system are arranged immediately beside each other in order to reduce the flow resistance level and to increase the speed of filling and emptying.

Title: Vacuum cleaner suction head
Inventor: GENSLER HORST
IPC: A47L9/02
Filed: 1998-09-28
Abstract: The cleaner suction head has a casing with a rear wheel or wheels, which rotate on shafts. The wheel shafts can be moved vertically in bearings.

Title: Clock signal synchronizing method especially for digital exchanges
Inventor: HIPP IMRE
IPC: H04J3/06
Filed: 1998-10-20
Abstract: The method involves providing a clock signal (ft) and a reference clock signal (fr). It is tested if a slope of the reference clock signal lies outside a predetermined tolerance range with respect to the slope of the clock signal. The clock signal is newly synchronized to the reference clock signal, if the result of the test is positive. When the result is positive, the slope position of the reference clock signal is changed about a predetermined phase value before the clock signal is newly synchronized. The clock signal is only newly synchronized if the slope of the reference clock signal lies outside the tolerance area even after the slope position change of the reference clock signal.
