Patent DE-4320096-A1 (DE)
Inventor: COENEN HUBERT DR ING
IPC: C02F3/28
Filed: 1993-06-17
Abstract: In biogas reactors of the UASB type, the biogas is separated off from the rising wastewater stream by staggered collection hoods in which a free surface is maintained at which gas transfer takes place. In the known cross-sectional shapes of the collection hoods, the free surface area when the water level is high is greatly decreased and gas transfer is correspondingly greatly hindered. According to the invention, therefore, a rectangular profile having a constant free surface area is utilised. The upper side of the collection hoods can be designed in a roof shape as a sliding surface for the sedimenting anaerobic sludge.

Patent DE-4335368-A1 (DE)
Title: Device for cleaning bottles
Inventor: PFANNENSTIEL HUBERT
IPC: B08B9/34
Filed: 1993-10-16
Abstract: The invention relates to a device for cleaning bottles in automatic bottle cleaning installations. The bottles, located in holders, are here guided by means of a continuously circulating carrier chain initially through various cleaning baths and finally, to clean the internal space, sprayed out with cleaning liquors and rinsing waters. The spray nozzles, which are arranged on a spray carriage, are guided along with the bottles over a selectable distance, the spray nozzles rotating slowly about their axis. Upon reaching the end point of the distance, the spray carriage is displaced back to the starting point of the distance by means of a suitable drive, the nozzles being rotated during this moving back in such a manner that no cleaning fluid emerges. The nozzles now spray out the row of bottles following in the bottle chain and, after a specific number of cycles, the nozzle holes are flowed through in each case in the opposite direction, which leads to self-cleaning of the nozzles.

Title: Method for structure generation in a semiconductor component
Inventor: LEE KANG-HYUN
IPC: H01L21/302
Filed: 1994-04-15
Abstract: It is known, for structure generation in a semiconductor component to apply a photoresist onto the layer to be structured which is located on a substrate, and to generate a photoresist structure from this photoresist by a lithographic process and to etch the layer to be structured by using this photoresist structure as an etching mask. The novel method provides, before etching the layer (22) to be structured, execution of an anisotropic etching process such that an etching byproduct (26) is formed on the side walls of the structure (23, 25) formed over the layer to be structured, after which the layer (22) to be structured is etched by using this etching byproduct (26) and the other structure (23, 25) lying over the layer to be structured as the etching mask. In this way a fine structure can be generated, with low expenditure and in a simple way, with structure intervals which are smaller than the limits intrinsically set by the exposure device used for photoresist structuring. Use, for example, in the production of large-scale integrated semiconductor memory components. <IMAGE>

Patent DE-4431189-A1 (DE)
Title: Fuel injection for vehicle IC engine
Inventor: HIMMELSBACH JOHANN DR ING
IPC: F02M53/06
Filed: 1994-09-01
Abstract: The engine fuel-injection management system includes monitoring of the temperature of the injected fuel and calculating the optimum temperature level. The fuel is heated by increasing the energy to the injectors and thereby generating additional thermal losses which directly heat the fuel. No separate heaters are required. The enhanced energy is obtained by increasing the voltage or current applied to the injector during the ignition cycle. For increased voltage the injector is supplied with a voltage greater than the remainder of the electrical system on the vehicle. The additional energy can also be provided by modulating the drive pulses for the injectors with a higher frequency signal. The electric leads to the injectors double as thermocouples to monitor the temperature.
