Abstract: A fuel injection system for internal combustion engines with a pressure step-up means is proposed, in which the fuel is pumped out of the low-pressure supplier into the injection nozzle via a feed line and is measured correctly in terms of time and quantity via a control line by the high-pressure part of the injection pump.

Abstract: For reducing the number of acoustic transducers required by a torpedo sonar for target searched the transducers are arranged in four particular zones at the curved contour of the torpedo bow forming a conformal sonar array. A circular first zone covers the vertex region of the torpedo bow and is surrounded by a ring-shaped second zone. Extending from said second zone on both sides of the torpedo are third lateral transition zones, which change over into fourth lateral zones of constant width ending at the great circle of said hemispherical or paraboloid-shaped torpedo head.

Abstract: The composition for removing or lightening hair color is in the form of a hair color lightening suspension and is mixed with an aqueous oxidizing composition immediately prior to use. The composition includes a combination of from 0.1 to 80 percent by weight of one or more organic lipophilic compounds, namely vegetable or animal fats, vegetable or animal oils, vegetable or animal waxes, paraffin hydrocarbons, higher alcohols or ethers, aliphatic and aromatic esters and/or silicone oils; from 0.1 to 40 percent by weight of at least one lipophilic inorganic or organic thickener, which forms an oleogel and/or lipogel with the lipophilic compounds; from 0.1 to 40 percent by weight of one or more hydrophilic inorganic or organic thickeners; from 10 to 65 percent by weight of at least one inorganic persalt; from 10 to 45 percent by weight of at least one alkaline reacting salt; and auxiliary substances and cosmetic additive ingredients, as needed.

Abstract: A tubular reactor characterized by having short static mixing elements separated by coalescing zones is used to conduct multiphase liquid/liquid reactions. Small droplets of one of the phases are dispersed into the other phase by the static mixing elements. These droplets coalesce and at least partially phase separate as the mixture passes through the subsequent coalescing zone. The tubular reactor is particularly suitable for nitrating organic compounds while forming low levels of improperly nitrated by-products and low levels of nitrophenolics.

Abstract: Device for the vacuum coating of mass produced products. By means of the ice small parts, such as screws and bolts, as mass produced products are highly productively coated by vacuum deposition or sputtering, also under plasma action. In a container is located a drum rotatable at high speed about its horizontal axis and in which the parts to be coated are fixed to the inner wall by centrifugal force. The surface of the inner wall is geometrically constructed such that the parts to be coated are reliably held and moved with it. The coating devices are located in the drum. A stripping device, whose spacing with respect to the inner wall is adjustable at programmable time intervals, is located in the drum and has an abutment surface directed opposite to the rotation direction.

Abstract: Process and device for electron beam treatment of bulk material where the bulk material is fed into a continuous stream by means of compression stages (3) which can be evacuated. It is dispersed and directed into a dosed irradiation chamber (1), passing in this chamber through an irradiation field in a free-fall process, and discharged from the irradiation chamber through a compression stage system (4). The invention enables electron beam treatment of biological materials to be carried out to particularly good advantage, e.g. in combatting harmful organisms in seeds.

Abstract: A sensor for automatically triggering safety devices in motor vehicles, the sensor has a housing having a housing recess with a base and a tilting body located in the housing recess, the tilting body serving as a seismic mass and triggering a control signal when a predetermined threshold value is exceeded, the tilting body having an edge and a base. The base of the housing recess is provided with knobs at least in the region of the edge of the tilting body. The base of the tilting body is flat at least in the region of the knobs.
