Patent DE-19634058-A1 (DE)
Title: Office chair for floors with carpeting
Inventor: BIRKENHEUER SVEN
IPC: A47C3/18
Filed: 1996-08-23
Abstract: The office chair has an automatically resettable rotation device mounted beneath the seating surface (14) and which causes automatic rotation into a position in which lateral skids (24) run along the direction of the seating surface, enabling easy sliding of the chair on a carpeted floor, when the chair is unloaded. The rotation device (16) only allows rotation when load is removed from a spring by a person sitting on the seat, whereby two cylindrical plastic sleeves with angled profiles disengage from shape locking to allow mutual relative rotation.

Title: Integral leak testing method for large volume test objects
Inventor: SCHROFF GERHART
IPC: G01M3/22
Filed: 1996-09-05
Abstract: The method involves placing a test object in a test chamber and pressurising the object with a test gas.  The test gas is distinguishable from the atmosphere and naturally occurring only in very low concentrations of preferably less than 100 ppb.  The test gas escapes into the chamber at any leakage points.  The escaping gas is preferably uniformly mixed with the air in the chamber by convection, and its measured concentration is used to determine the size of the leak in the test object.

Patent DE-19724074-A1 (DE)
Inventor: WEIS HANS-JUERGEN DR
IPC: C10G9/28
Filed: 1997-06-07
Abstract: According to the invention, liquid residual oil from processing crude oil, natural bitumen or oil sand is mixed in a mixer with hot coke as a heat carrier (heat-carrier coke) whereby 60 to 90 weight per cent of the residual oil is evaporated. The proportion of residual oil which has not evaporated, i.e. the part containing metalliferous asphaltenes is converted to oil vapour, gas and coke in the mixture with the heat-carrier. The gases and vapours are extracted from the mixer separately from the granular coke and are subsequently cooled to obtain an oil product and gas. The coke extracted from the mixer is re-heated and returned to the mixer as a heat-carrier. The liquid residual oil is mixed with heat-carrier coke in the mixer according to a weight ratio of 1:3 to 1:30, said heat-carrier coke being at a temperature of 500 to 700  DEG C. A residual liquid film forms on the granules of heat-carrier coke as a result of this mixing process. The majority of said residual film evaporates in the mixer at a lowest possible operating temperature of 450 to 600  DEG C. The remaining residual liquid film on the coke is converted to oil vapour, gas and coke during a retention time of 6 to 60 seconds. Dry, pourable coke is extracted from the mixer, said coke being essentially free of any liquid constituents. The gases and vapours produced are extracted from the mixer after a retention time of 0.5 to 5 seconds.

Patent DE-19733923-A1 (DE)
Inventor: LINGENFELDER WOLFGANG
IPC: E04B2/74
Filed: 1997-08-06
Abstract: The invention relates to dividing walls, especially for exhibition booths. Said walls consist of several, intrinsically rigid partition elements which are essentially formed by a frame and at least two panels covering the outside of the frame. The individual partition elements can be detachably interconnected by means of coupling members. Each coupling member essentially consists of three partial elements, i.e. two frame connections (7, 49) and a joining piece (8, 46). Both frame connections (7, 49) are arranged on the outer side of the vertical frame piece (6) of two partition elements that are to be joined. The frame connections (7, 49) and the joining piece (8, 46) can fit together like a clip. This enables individual partition elements to be assembled starting from a pre-assembled dividing wall by removing individual joining pieces in a targeted manner.
