Title: Operation of natural draught cooling tower - uses cooling water indirectly warming incoming air via incorporated partition
IPC: F28C1/14
Filed: 1992-09-23
Abstract: In the cooling tower cooling water warms the inlet air in direct contact, thus forming a humid air stream, while cleaned flue gases are introduced into the humid air stream. Before the water directly contacts the inlet air, it warms indirectly the inlet air via an intermediate partition. Thus a dry air stream is formed and used to form a jacket round the humid air stream. The cooling tower has a vertical axis shell with inlet at lower end and outlet at the top. The cooling water feed is coupled to a wet portion in the inlet region, above which is an opening for the cleaned flue gases. USE/ADVANTAGE - For power plant cooling water, with increased tower shell protection against corrosive components of cleaned flue gases.

Patent DE-4326182-A1 (DE)
Title: Transmission control for vehicle - indicates if transmission ratio can be raised to next level without losing vehicle speed.
Inventor: SCHULZE BERND GUIDO DIPL ING
IPC: F16H61/02
Filed: 1993-08-04
Abstract: The transmission control system monitors vehicle speed, gear ratio and engine torque. Using a programmed table of engine torque versus driving conditions, the system determines the available torque if the gear ratio is switched up one setting and from the computed torque the system determines if the current road speed can be maintained with the higher gear setting. The control program is continuously updated to take account of the vehicle loading and vehicle drag, e.g. if a roof-rack is fitted. The switch-up signal is activated if the new computed torque is greater than, or equal to the current torque minus the product of the vehicle mass and the current acceleration. The system is applicable to manual gear changes and automatic transmissions. ADVANTAGE - Simplifies gear changing, reduces switching rates when under load.

Title: Bio-film process for denitrification of waste water
Inventor: SIEKER CARIN DIPL ING
IPC: C02F3/12
Filed: 1994-01-31
Abstract: A biological film denitrification process comprises contacting the biomass alternately with effluent water containing biodegradable organic materials, and effluent water containing nitrate. The process is effected in an assembly with two independent hydraulic zones; an enrichment and separation zone, (1) and a denitrification zone (2). These zones are arranged over each other, and each has an inlet and outlet. Each zone is differently charged, first with organically-laden effluent water (3) and then with effluent water containing nitrate (5). The assembly has a biomass system with the following features; the microorganisms form a biofilm on freely moving carrier particles which  have a lower density than effluent water, through which they therefore rise; the microorganisms are introduced into the enrichment and separation zone (1) and by reason of their upthrust climb against the flow of effluent water into the denitrification zone (2); the microorganisms are removed from the denitrification zone (2) and are returned to the absorption and separation zone (1), where they again rise through the denitrification zone (2).
