Patent DE-3933232-A1 (DE)
Title: IC engine fuel injection pump and nozzle
Inventor: KRUEGER HERMANN DR ING
IPC: F02M57/02
Filed: 1989-10-05
Abstract: the pump nozzle comprises a nozzle which is guided so as to be axially displaceable against a spring force out of a position in which it closes off the injection openings.  When fuel pressure is increased by the displacement of the  pump piston, it performs a stroke movement in an injection chamber into a position in which it opens up the injection openings, where the end of the nozzle needle facing the pump piston is in the form of a guide cylinder.  This is open at its front end, for the facing end region of the pump piston. The cylinder is provided at various levels with openings for supplying fuel and for conveying fuel into the injection chamber and the area of the nozzle needle which is acted upon in the injection chamber by the fuel pressure in the axial direction being greater than that of the end face of the pump piston.

Patent DE-4040641-A1 (DE)
Inventor: ROESSLER ERICH
IPC: D06M15/277
Filed: 1990-12-19
Abstract: Highly effective compositions for the water- and oil-repellent finishing of fibre materials, in particular textile materials, contain at least two components which are aqueous dispersions. One of the dispersions contains a copolymer composed of a fluorine-containing (meth)acrylate, vinyl chloride and a fluorine-free (meth)acrylate, and also ethoxylated alkylphenol. The other dispersion contains either a copolymer composed of a fluorine-containing acrylate, vinylidene chloride and a fluorine-free (meth)acrylate and also ethoxylated fatty acids or an isocyanate blocked by means of an oxime, a fluorine-containing oligo- or polyurethane and an ethoxylated fatty amine (salt). The compositions lead to a pleasantly soft feel of the finished fibre material and in many cases reduce the bleeding of dye in the case of dyed textiles.

Title: Degradation of chlorinated aromatic cpds., esp. in soil - by enzymes produced from cellular slime fungi e.g. dictyostelium
Inventor: WURSTER BERND PROF DR
IPC: A62D3/02
Filed: 1991-05-10
Abstract: Biological degradation of chlorinated aromatic cpds. (I), esp. in soil, is carried out by enzymes produced from cellular slime fungi. The soil contaminated with (I) is broken up to ensure adequate availability of oxygen and nutrient, and sterilised in a bioreactor at 30-120 deg.C. The nutrient (if liq. or solid form), bacteria and slime fungi (as cells or spores) are added to the soil. Due to the multiplication of bacteria, growth of fungus is enabled, which in turn causes a redn. of density of bacteria (which serves as the nutrient source). The fungus can then enter a differentiating phase. Alternatively, the fungi are cultivated using bacteria or a nutrient soln. in a fermenter and then distributed onto the soil. USE/ADVANTAGE - Useful for degradation of harmful materials such as herbicides, insecticides, and PCBs. The fungi use bacteria as nutrient rather than (I). The fungus used is, e.g., Dicytostelium discoideum, which degrades (I) due to the similarity of (I) with a differentiation inducing factor produced by the fungi.ate

Inventor: HEES EBERHARD
IPC: B60G17/0185
Filed: 1991-07-17
Abstract: For the active control of a suspension system designed with a plurality of actuators (1-4), the position actual values (Z1-Z4) and the pressure actual values (Pactual-Pactual4), and also the instantaneous longitudinal acceleration values (Ax) and the instantaneous transverse acceleration values (Ay) of the vehicle body are supplied to the computer of a status controller (11). First desired pressure values (Pdesired/1-Pdesired/4) for the individual actuators (1-4) are calculated in this computer, taking into consideration the respective significances. A second desired pressure value (Pdesired/1) which corresponds to the simulation of desired spring/damper behaviour is again determined from the length actual value (Z1) and the pressure actual value (Pactual) for the individual actuators (1). The two desired values (Pdesired/1, Pdesired//1) associated with an actuator (1) are linked to form a resultant desired pressure (Pdesired-res) and this resultant desired pressure (Pdesired-rest) is used, after comparison of desired value and actual value, to actuate supply and discharge valve mechanisms (1c) of the respective actuator (1). <IMAGE>
