Patent DE-4037765-A1 (DE)
Title: Bio-reactor for producing carbon di:oxide gas in bottled drinks - with yeast etc. carried on porous fabric layers and spirally wrapped in filter layers, leaving central hole for nutrient access
Inventor: QUETSCH KARL-HEINZ
IPC: C12G1/073
Filed: 1990-11-28
Abstract: A bioreactor produces gas in drinks by fermentation without clouding with materials such as yeasts or microorganisms.  The active materials are enclosed in a single or multi-layer porous filter material. Embedding the microorganisms between porous filters prevents cavity formation, pressure build-up and obstruction to diffusion. One or more layers of a porous fabric are spirally wound with the filter layers to produce a bioreactor with a central hole through which nutrients can easily reach the microorganisms. USE/ADVANTAGE - Creates carbon dioxide in sparkling drinks without the appearance of cloudiness. Diffusion is unhindered and uncontrollable pressure build-up is avoided.

Title: Method of improving efficiency of IC engine - involves mixing combustion air with water and ionised oxygen@
Inventor: WANKA EDWIN DIPL ING
IPC: F23L7/00
Filed: 1991-04-25
Abstract: The combustion process in an internal combustion engine, a gas turbine, or a steam boiler, is made more efficient in the following way. The moisture content of the main stream of combustion air is increased to a defined level. Before this stream of air with increased moisture content reaches the combustion chamber, it is mixed with ionised oxygen. The stream of moist air is heated causing the disassociation of the hydrogen ions which then react with the ionised oxygen atoms to increase the heat output during combustion. USE/ADVANTAGE - Method of improving the thermal efficiency of internal combustion engines and steam boilers

Patent DE-4121021-A1 (DE)
IPC: B27G19/08
Filed: 1991-06-26
Abstract: A method and an apparatus are disclosed for separating or slitting a rigid material, in particular a piece of wood, having a modulus of elasticity of between 50,000 and 400,000 kg/cm2. A narrow tool having chip-removing elements, in particular a circular saw blade, produces a slot or kerf of finite width in the material at a cutting speed of more than 40 m/s. After the chip-removing elements having passed, a separator element bends a side piece out of the slot plane so that after the chip-removing elements have passed, the side piece is always at a distance from the tool. When viewed along the feed direction of the material, the separator element is provided with a hump at a distance from its periphery adjoining the tool and being first to come into contact with the material when the material is fed in. An imaginary connection line extending between the hump and the chip-removing elements is at a distance above a first portion of the separator element lying between the hump and the periphery.

Title: Fitting card wire to opening rollers for rotor spinning - using longitudinal compression of roller body to grip wire and eliminate gaps between body and wire
Inventor: SCHMOLKE KARL-HEINZ
IPC: D01H4/32
Filed: 1991-10-02
Abstract: An opening roller for rotor spinning machines has card wire spirally wound into grooves machined into a body.

Abstract: A steam generator has a flue gas channel with several sections (3, 4, 5). A first vertical section (3) is linked to an equally vertical third section (5) by a second section (4) that extends at least approximately in the horizontal direction. In order to prevent the flue gas channel from being obstructed or distorted by thermal expansion, the first section (3) is suspended in the support structure (1) by support elements (16, 19) which adopt an inclined position (16', 19') with respect to the vertical in their cold state and which extend parallel to the vertical in their hot state. The flue gas channel remains thus a structural unit whatever its operational state, allowing free thermal expansion both in the vertical and in the horizontal directions.
