Abstract: A compensating tank for a hydraulic motor vehicle brake system, having a housing including a housing upper part and a housing lower part and having a device for monitoring the tank filling level of the compensating tank, including a switching unit, which is welded to the housing and has a plug connector, and including a sensor or switching element which can be switched by a transducer at a switching point S at which the switching unit generates a signal for an electronic control unit. The housing has a depression for holding the switching unit, with the switching unit having a base body composed of plastic, which base body is welded to the housing in the depression, and with the depression being provided such that the base body of the switching unit forms a planar surface with the housing.

Abstract: A combustion chamber for a gas turbine is provided. The combustion chamber comprises at least one first and one second jet carrier, of which at least one is provided for injecting an operating gas in the combustion chamber such that waste gas fanned in the flame zone thereof is circulated to a mixing zone of the first jet carrier. In order to achieve a compact combustion chamber, the jet carriers are positioned in relation to each other such that waste gas from the flame zone of the first jet carrier flows directly to the mixing zone of the second jet carrier.

Abstract: An equalizing tank for a hydraulic motor vehicle brake system, with a housing including a housing upper part and a housing lower part, and with a device for monitoring the fluid level in the equalizing tank, the device including a switching unit which is fastened to the housing and has a plug-in connector and a contact carrier, a portion of which projects into a guide pipe which extends into an interior space of the tank, and a sensor element or switching element which is arranged on the contact carrier in the region of the guide pipe and which can be switched by a transmitter in a switching point at which the switching unit generates a signal for an electronic control unit.

Abstract: The invention is based on a gas turbine burner comprising a combustion zone for burning a mixture consisting of combustion exhaust gas to which fuel gas is added, and comprising a fuel intermixing arrangement having a fuel nozzle for spraying the fuel gas into the combustion exhaust gas. In order to achieve low-pollutant and uniform combustion, it is proposed that the fuel intermixing arrangement be designed for spraying the fuel gas into the combustion exhaust gas at at least 0.2 times the speed of sound.

Abstract: A regulating device for regulating the course of a gas turbine plant has at least one sensor for sensing a measurement variable and for outputting a measurement signal which represents the measurement variable; at least one adjusting system for influencing air and/or fuel supply to a combustion chamber of the gas turbine plant on the basis of a correcting variable; and a regulator connected to the at least one sensor so as to receive the measurement variable and to the at least one adjusting system for outputting the correcting variable, the regulator being designed to determine the correcting variable on the basis of the measurement variable received and its deviation from a pilot variable. At least one sensor is designed to sense the variation in time of at least one burner or combustion chamber parameter as measurement variable.

Abstract: This invention relates to a burner, especially a gas turbine burner, wherein a Helmholtz resonator downstream of a fuel inlet position in directly linked with a burner channel. In this manner, combustion oscillations do not arrive at the fuel inlet position, thereby reducing acoustic disturbances and air ration deviations which are the main cause for the formation of combined oscillations. The invention also relates to a method for operating a burner and a gas turbine.

Abstract: The invention relates to a gas turbine comprising a combustor that extends into a combustion chamber. The port of the combustor is surrounded in a ring-shaped manner by a Helmholtz resonator, whereby combustion oscillations are effectively suppressed due to close contact with the flame while irregularities in temperature are prevented.

Abstract: Disclosed is a container for supplying pressure fluid to a master cylinder of a hydraulic motor vehicle brake system. The container includes a filling reservoir (2,29) arranged at a first level (14,45) and including a fill hole (15,31) and a discharge opening (16,32), a main reservoir (3,30) arranged at a second level (19,46) and including an inlet opening (35, 44 and discharge openings (47,48), as well as a device 8 for monitoring the container's state of filling, with the first level (14,45) being disposed above the second level (19,46), and the filling reservoir (2,29) and the main reservoir (3,30) being interconnected. A device (17,33) for filling the main reservoir is integrated with the container and includes one or more channels (18,34).

Abstract: A process for the preparation of an anthranilamide of the formula ##STR1## in which R.sub.1 and R.sub.2 each independently is hydrogen orC.sub.1 to C.sub.4 alkyl, or R.sub.1 and R.sub.2, together with the nitrogen atom to which they are bonded, form a heterocyclic ring,comprising reacting isatoic anhydride of the formula ##STR2## with an approximately equimolar amount of an amine of the formula ##STR3## in water at a pH of about 7 to 10.5 and a temperature of about 20.degree. to 100.degree. C. Advantageously the reaction is effected in the presence of a buffer system comprising an amine of the formula ##STR4## plus at least one of a hydrohalide and carbonic acid salt of such amine, e.g. ammonia or a lower alkyl amine plus the corresponding hydrochloride and/or carbonate.
