Patent DE-19634615-A1 (DE)
Inventor: KOECK GERHARD
IPC: G10K11/172
Filed: 1996-08-27
Abstract: A sound absorbent component whose chambers present thin side walls and form acoustic resonators of the spring mass system type. The thin side walls are placed next to each other or integrated with each other so that in each case they form partitions (4) assigned to one chamber and the chambers (14) with the partitions (4) are assembled as a compartment-like chamber system. The partitions and the chamber system can be manufactured in a simple cost-effective manner by a deep-drawing type process from a flat foil using thin rods (9) which form, in particular, parts of a deep-drawing grid.

Patent DE-19649244-A1 (DE)
Title: Machine for converting a mixture of biological waste and renewable materials into, e.g. oil, hydrogen, methane, proteins and heat
Inventor: SCHIFF GERHARD DIPL ING
IPC: B09B3/00
Filed: 1996-11-18
Abstract: A switch operated machine is used to treat heterogeneous biological waste and renewable raw materials to form a process cycle that yields useful materials from the solids and the effluent bound inside them. An anaerobic fermentation or a Bayer low temperature conversion process, or a combination of these two processes, can be carried out in the single-unit machine, depending on the composition of the biological material. Sensors are used to determine various biological material parameters and the processed data is used to select the process (combination). Regulators and sensors control material supply in order to achieve a chosen adjustable co-fermentation process for a given relationship between the substances being fermented, in order to optimise synergy. Effluent generated is purified by passing it through a sewage treatment unit containing plants and after that it is converted into useful materials in an algae reactor. Slides are used to open or close compartments in the sewage treatment unit in order to alter the unit surface area. Plant growth varies in the different compartments. The increased purification capacity created by allowing the plants to grow deeper roots to approximately 180 cm in depth reduces the surface area taken up by the machine. Deeper root growth is achieved using a mixed culture of Phragmites communis, forming roots in both the top and bottom layers in the unit. Effluent contaminated with salts leaving the unit can be converted into a useful product in the algae reactor. Hydrogen is formed from methane and oil in the low temperature conversion process with the aid of fuel cells as energy converters. Methane generated is used to drive the heat absorption pump for generating heat and/or cold.

Patent DE-19802048-A1 (DE)
Title: Injection molding tool
Inventor: BAUDISCH ANDREAS
IPC: B29C45/16
Filed: 1998-01-21
Abstract: The tool has two or more independent hot runner systems (3,4), each with a needle valve (5,6,7) opposite the component. Location of the injection points and hot runners is determined by the rheological composition of core/skin material and flow through these can be freely chosen in the injection tool.  Preferred Features: Hot runner channels may be located in both the moving and fixed tool halves. Each hot runner channel (3,4) may have either a single or an unlimited number of hot runner nozzles (13,14), each of which can be independently controlled. Additional independently controlled hot runner channels may be incorporated to allow additional materials to be injected, e.g. for injecting three melt components in the molding. The independent hot runners permit cascade injection molding or the introducing of core material into specific areas. The locations in the component at which core and skin material or only skin material exist are controlled by closing or opening the hot runners. In an alternative tool design closure of the hot runner channels may also be effected by moving slides between the hot runner and component. A runner between the component and hot runner channels may also be closed by moving slides.

Abstract: The invention relates to a tube (7 or 21) with an expansion area (25 or 25A, 25B) presenting a roughness (26 or 26A, 26B). In this area, for example a heat exchanger tube (7A) can be fixed by expanding the tube wall (23).

The tube can be used both as a repair sleeve (21) (sleeve tube) for repairing defective heat exchanger tubes (7A) but also as a heat exchanger tube (7) which can easily be fitted into the tube bottom (9) of a steam generator (1). The invention also relates to a method for producing a tube (7 or 21) having an expansion area (25 or 25A, 25B).
Patent DE-19813551-A1 (DE)
Inventor: BAUERSCHMIDT WERNER
IPC: H04N7/62
Filed: 1998-03-27
Abstract: The invention relates to a method for transmitting time-critical data packets in digital wireless transmission systems. Time-critical data packets are used e.g., in the transmission of MPEG-coded signals, since information about the temporal positions of the data packets in relation to each other must be known in the MPEG decoder. The aim of the invention is to enable data packets of this type to be transmitted via a propagation time-constrained transmission link. To this end, time information relating to the temporal position of a particular data packet is tagged onto said data packet at the sender end. This time information is then used at the receiver end to re-establish the original temporal positions of the individual data packets in relation to each other.
