Abstract: In a method and a device for controlling a brake system, the wheel brake pressure is set at the wheel brakes electrically as a function of the driver's braking input. The high-pressure supply arrangement for pressure buildup, for which at least one pump and one accumulator are provided, is monitored by comparing the change in accumulator pressure to a least one permissible limiting value. In the case of a fault in the pressure supply, it is made possible for the driver to grip through hydraulically to the wheel brakes.

Abstract: A method is described for examining a solidifying and/or hardening material such as cement, concrete or the like, using ultrasound waves emitted by an ultrasound transmitter, which penetrate the solidifying and/or hardening material, are continuously measured and analyzed. During solidification and/or hardening of the material, the signal shapes of the ultrasound waves penetrating the material, are recorded. The change with time of the compression wave velocity and/or the relative energy of the ultrasound waves and/or the frequency spectra of the ultrasound waves is extracted from the ultrasound wave shapes during the entire course of solidification and/or hardening of the material. This change with time of the compression wave velocity and/or the relative energy of the ultrasound waves and/or the frequency spectra of the ultrasound waves is approximated through a compensating function, preferably the Boltzmann function.

Abstract: A combustion chamber for a rocket engine expels a hot stream of gas and has a cooling device. The inner wall of the combustion chamber adjoins the cooling device and contains depressions formed in such a way that the stable outer layer of the stream of gas that forms in the proximity of the inner wall of the combustion chamber during operation of the combustion chamber is destabilized in the area of the depressions.

Abstract: Within an injector housing, a nozzle needle comprising a nozzle needle shaft is accommodated in a first guide boring in a longitudinally displaceable manner. A nozzle prechamber which is arranged in front of the nozzle needle shaft and which is situated on the fore-part of the first guide boring is supplied with fuel via a high pressure channel. A control valve permits a control chamber, which is coupled to the nozzle needle and which is subjected to the action of highly pressurized fuel, to be relieved from pressure by opening the nozzle needle. According to a second embodiment, a spring chamber is configured as a high-pressure chamber on the rear side of the first guide boring that guides the nozzle needle shaft. The spring chamber is separate from the control chamber and contains a readjusting spring that impinges upon the nozzle needle in a direction of closure. This configuration prevents fuel exiting the nozzle prechamber from overflowing over the guide boring which guides the nozzle needle.

Abstract: The braking effect in a vehicle is set in the sense of preventing a tendency to lock-up with at least two wheels which are arranged on at least one axle on the right and left and whose motion characteristics are detected. The braking effect on the two wheels is set jointly, with at least two operating modes (select low, select high) being provided; they can be selected depending on the coefficients of friction prevailing on the wheels and/or depending on the vehicle speed. An operating mode is selected according to the value of the prevailing coefficients of friction when there are coefficient of friction differences of a preselectable lower value. As an alternative or in addition, an operating mode is selected according to the detected vehicle speed when there are coefficient of friction differences of a preselectable greater value.

Abstract: A device for wiping the surfaces or rotors used to portion mixed materials. The device removes adhering materials, such as cookie dough, from the cutting or metering surfaces. Typical application is for use in large automated bakeries or cookie manufacturers wishing to transport larger slabs or chunks of cookie dough from a mixer to machines which portion the dough prior for baking or freezing. The device has a wiper located proximate to the rotors. The device then moves the wiper along the rotors to release the adhering materials.

Abstract: A method and device for controlling a braking system of a motor vehicle in open loop, in which the wheel-brake pressure in the individual wheel brakes is adjusted via closed pressure-control loops. Different secondary braking operations are initiated depending on the fault condition. The faults are detected on the basis of a model which takes into account the prevailing operating state of the braking system.

Abstract: A method and a device for controlling a braking system of a motor vehicle in open loop, in which a driver's braking input is converted into setpoint wheel-brake pressures for the individual wheel brakes, and the wheel-brake pressure is adjusted to the setpoint wheel-brake pressure in view of the measured wheel-brake pressure. Various secondary braking operations are initiated as a function of the type of fault. In response to a serious fault such as failure of the electrical energy supply, of the pressure supply, or an electrical fault in the control unit of the braking system, the valve arrangements controlling the wheel-brake pressures are switched over into a currentless state, and in response to a fault in detecting the driver's braking input, only the valve arrangements allocated to the front axle are switched into a currentless state.

Abstract: A wall structure for fuel-cooled engine walls, with a cooling structure having an inner wall to which hot gas is admitted; an outer wall located at a spaced location therefrom; as well as a plurality of webs, which connect the two walls and divide the intermediate space between the walls into cooling channels (19), and with a support structure in the form of at least one stable outer jacket. The cooling structure is slotted from the outside in the area of each web, wherein the slots (22) pass through the outer walls and the centers of the webs into the area of the inner wall. The support structure is designed as an elastically nonrigid support structure at least in the area joining the cooling structure and/or is located at a spaced location from the cooling structure.

Abstract: Cooling of engine walls with fuel, wherein the walls have a structure which has an inner wall, to which hot gas is admitted during the operation, a colder outer wall, as well as a plurality of webs which connect the walls and divide the hollow space present there into a plurality of cooling ducts.The fuel is introduced in the cold state into the wall structure, is delivered through the cooling ducts while absorbing heat via the inner wall, and is subsequently used to generate thrust.A hot fluid flow taken from the engine is admitted during the operation from the outside to the "cold" outer wall of the wall structure, through which fuel flows, and this "cold" outer wall thermally expands as a result, or its thermal contraction is reduced.

Abstract: Injection element of coaxial design for rocket combustion engines and for operation with two propellants, at least one of which disintegrates into drops with difficulty only, comprising a central body for the more readily disintegrating propellant (oxidant), whose flow channel generates a conical drop distribution at the outlet; a sleeve concentrically surrounding the central body to form an annular flow channel for the less readily disintegrating propellant (fuel); and a flow splitter which splits this propellant flow into a plurality of individual flows. The flow splitter has an even number of passage channels, which are uniformly distributed around the central body and cooperate in pairs in terms of an impact atomization ("impinging"), wherein the axes of two adjacent passage channels each intersect downstream of the flow splitter and upstream of their points of impact on the propellant cone discharged from the central body.
