Patent DE-19645311-A1 (DE)
Inventor: NERGER CHRISTIAN
IPC: C02F3/06
Filed: 1996-11-04
Abstract: A method for phased biological treatment of raw untreated sewage entailing a biofilter, which has a fixed bed of supporting material covered with micro organisms located in a container. The raw untreated sewage is fed into the container batchwise while the withdrawal of previously treated waste water from the biofilter occurs in an exchange phase through the displacement of the subsequent batch of raw untreated sewage. The waste water passes through the fixed bed during a circulation phase whereupon an exchange of materials between the fixed bed and the constituents occurs in the waste water. The raw untreated sewage is continuously treated as a result of an accumulation of large quantities of raw untreated sewage and a low concentration of inflowing raw untreated sewage.The raw untreated sewage passes through the biofilter with simultaneous separation of waste water by displacement involving further raw untreated sewage and exchange of materials.The raw untreated sewage is treated discontinuously during operations involving partial hydraulic load and high concentration of inflowing raw untreated sewage. The raw untreated sewage is fed into the biofilter in batches by displacement and the exchange of materials occurs in a circulation phase with or without reduced simultaneous feed of raw untreated sewage and withdrawal of waste water. The process is controlled continuously or discontinuously according to requirements.

Title: Automatic steering system for motor vehicle
Inventor: KAGAWA KAZUNORI
IPC: B62D6/00
Filed: 1996-11-04
Abstract: The automatic steering control operates in certain conditions and steers the vehicle via a servo motor while the steering wheel is blocked. When the manual steering is reset a servo drive first moves the steering wheel until its setting coincides with that of the steering column and locks the two together. The change over from automatic steering to manual follows a progressive course. An indicator reminds the driver when the steering is by automatic control. A locking mechanism holds the steering wheel during automatic steering. The two servo motors operate together in the change over period between automatic steering and manual steering.

Title: Angle of advance determination in IC engine
Inventor: HESS WERNER
IPC: F02P5/152
Filed: 1996-12-10
Abstract: A primary unit (10) holds in memory engine characteristics, derived from test bench results bearing e.g. on fuel consumption, pollutant emission, etc., generally relating the range of angles to selected parameters such as speed and load.
