Patent DE-4001855-A1 (DE)
Title: Biological treatment of organically contaminated aq. liq. - using biomass filtration and composting system modified by addn. of anaerobic fixed filter reducing molecular nitrogen
Inventor: WAGNER FRIEDRICH DR ING
IPC: C02F3/28
Filed: 1990-01-23
Abstract: In biological treatment of aq. liqs. contaminated with organic materials and having a high nitrogen content, the water passing through a biomass filter body acting as an aerobic region, and from whose outlet the treated water is taken, is in addition passed through an anaerobic region contg. sessile microorganisms, in which its nitrogenous content is converted into molecular nitrogen. This conversion may also take place under aerobic conditions. The anaerobic region consists of a fixed filter bed arranged upstream of the aerobic biomass filter body, and a part of the water leaving the outlet of this filter body is recirculated to the inlet of the anaerobic region. The suspended solids content of the raw water and microbiologically produced sludges are retained in the biomass filter body. A number of biomass filter bodies operating in series may be used. The water may be stored in a holding vessel, in which any sludge is retained, after leaving the biomass filter body. USE/ADVANTAGE - Used in the treatment of waste waters having a high nitrogen content, and at the same time producing a biomass compost suitable for use as a fertiliser. The used biomass from the biomass filter bodies is removed and preserved for future use as fertiliser, and this invention allows a purified water and a suitable fertiliser material to be produced while treating waters which are heavily contaminated with nitrogen compounds.

Title: Tubular guide piece for IC engine gas channel - incorporates bimetal slotted end area assuming different shapes dependent upon temp. conditions
Inventor: HUEBNER WALTER
IPC: F02B29/02
Filed: 1990-02-15
Abstract: The channel (14) involved in the IC engine is for additional air, and the guide piece (1) is heatable at least in parts. The channel is located in the cylinder head (10) in the vicinity of the inlet valve (12). The temp. of the guide piece is determined by that of the cylinder head in the area of the additional air channel, and is also influenced by that of the air flowing through the channel. The slots in the guide piece are formed by sepd. tongues in its end area which, dependent upon temp., move away from or toward each other. Where the tongues move towards one another, the cross-section for flow purposes is narrowed, and the amt. of air entering is accelerated. Shape alteration of the guide piece end area can also produce a turbulent effect. USE/ADVANTAGE - To influence both quantitatively and qualitatively the input air flow in an IC engine.

Patent DE-4009285-A1 (DE)
Inventor: WIMMER WOLFGANG DIPL PHYS DR
IPC: F02D41/14
Filed: 1990-03-22
Abstract: The invention relates to a process for monitoring the power output of the individual cylinders of a multicylinder internal combustion engine. During the working cycle of each cylinder, the instantaneous speed over a given angle of rotation of the crankshaft is determined and squared. Within each working cycle of the internal combustion engine, the mean linear increase or decrease in n<2> is subtracted from the actual n<2> profile to obtain a dynamically corrected n<2> profile, and for each cylinder the difference between the corrected n<2> values is calculated to obtain the ignition top dead centre of said cylinder and that of the next cylinder in the firing sequence. If the difference exceeds a predetermined threshold value, this is a reliable indicator of a combustion misfire. Dynamic variations in n<2> due to accelerating or braking are eliminated by correcting the n<2> profile.

Title: Bin for handling waste material - has hinged flaps in floor which are opened automatically to discharge bin contents
Inventor: ECKART GERHARD
IPC: B65F1/12
Filed: 1990-05-31
Abstract: The bin is used for storing waste material.   It is of cylindrical form and has a floor consisting of two hinged flaps.  The bin is lifted by a crane with the crane hook engaging a device which grips the upper end (36) of a rod (26) which can slide vertically in a guide (32) in the bin cover (14).

Patent DE-4018583-A1 (DE)
Inventor: WUEST WILLI DR
IPC: C07H15/04
Filed: 1990-06-09
Abstract: Alkyl glycosides are produced by direct synthesis from higher monofunctional alcohols and powdered glycoses, in particular anhydrous glucose and/or glucose monohydrate, in the presence of acid catalysts at elevated temperatures. The reaction chamber is maintained under reduced pressure and the glycose is introduced after a delay into the reaction chamber containing an excess of the acid catalyst and alcoholic reagents heated to the reaction temperature. Water released in the reaction mixture is removed from the reaction chamber in the gaseous phase. A partial flow is withdrawn from the liquid reaction mixture and conveyed to a preliminary mixing zone, into which the powdered reactant is introduced simultaneously, where it is processed with the liquid partial flow to a paste and conveyed through a downstream intensive mixer to the reaction chamber. This pressure in the preliminary mixing zone is equalized directly and simultaneously with the reduced pressure in the reaction chamber by the intensive mixer and with atmospheric pressure by the conveying device for the powdered glycose. The consistency of the paste formed in the preliminary mixing zone is chosen so that this paste can be used as a sealant for pressure equalization and hence as a so-called "living seal".
