Abstract: A continuous flow steam generator with a double-flue construction has a vertical gas flue with an ascending conduction of fuel gas. The combustion chamber rear wall is inclined inwards and towards the combustion chamber in an upper part region and thereby forms, with the bottom of an adjoining horizontal gas flue, a nose which projects into the combustion chamber. Some steam generator tubes of the lower part region of the combustion chamber rear wall are led upwards, uninclined, as supports for the combustion chamber rear wall, as far as a supporting structure located outside the conduction of the fuel gas.

Abstract: The invention relates to a method for operating a ferroelectric memory configuration in the VDD/2 mode. The memory configuration has a large number of memory cells which each have at least one selection transistor, one storage capacitor with an upper and a lower electrode and one short-circuiting transistor whose source-drain junction is connected in parallel with the storage capacitor. After a read or write procedure in which the memory cells are driven via respectively associated word lines and via respectively associated bit lines which are precharged in a precharge phase, the short-circuiting transistor is driven during a standby phase and in the process short-circuits the electrodes in the storage capacitor. The method is characterized in that the time of the standby phase coincides with the time of the precharge phase and, in the process, the bit lines are at a different potential with respect to that of the two electrodes of the storage capacitor.

Abstract: A configuration for triggering a restraining device has firing elements that are optically fired by an associated triggering device. In addition, an optical check signal can be transmitted to the firing element by the triggering device. An evaluation circuit evaluates light signals that have been transmitted to the triggering device. As a function of an evaluated, received light signal, a disable signal, by which emission of a firing signal is prevented, is generated by the evaluation circuit.

The airflow blown against the window is substantially laminar and the air is extracted in an upper region of the window. A dew point is lower than the window temperature in a region of extraction being the upper region of the window, and an absolute humidity of the blown air is lower than that of the extracted air.

Abstract: A brake value signal transmitter that is to be connected to a brake pedal of a motor vehicle senses activations of the brake pedal with a plurality of sensors and converts them into electrical signals. The brake pedal is connected via a rotatably mounted pressure rod to a piston that can be displaced in the interior of a cylinder. A pressure space that is filled with a gas, has a variable volume, and can be filled at least partially with hydraulic oil is provided in the cylinder. The gas is compressed by the piston when the brake pedal is activated, and in the process increases a reaction force acting on the brake pedal.

Abstract: A method for cooling metal components highly heated in a chamber includes effecting a uniform cooling of an entire metal component. The metal component has regions each with a given mass, some of the regions having a larger mass than others of the regions. Housings are provided around regions with the relatively larger masses. The regions are subjected to the inert cooling gas in a controlled manner to a differing extent based upon the mass size. The housings are individually subjected separately with the inert cooling gas. A treatment device for cooling metal components includes a reservoir for holding inert cooling gas and a chamber for receiving a metal component to be cooled. The chamber is connected to the reservoir and has a housing for each of the regions with the larger mass. Each of the housing has an inlet orifice separately connected to the reservoir.

Abstract: A demodulator of an evaluating unit for a device for detecting objects derives a useful signal from a supplied input signal with the aid of a carrier signal. The demodulator further derives a test signal with the aid of a modulated carrier signal. An evaluator detects as a function of the useful signal whether an object is being detected and, as a function of the test signal the functionality of the device.

Abstract: A decoder has a first memory for storing a coded first image. The image is stored in the first memory until it has been decoded at least twice. The results of the decoding operations can be supplied to a playback device. The invention makes it possible to dispense with an output frame buffer for the decoded first image, and thus only little memory is required in the decoder.

Abstract: At least two algorithms are assigned to at least one defined algorithm. Each of these two algorithms has a different probability of being the next algorithm to be executed during and/or after execution of the defined algorithm. Of the two assigned algorithms, the one which is in fact executed next is the one with the greater probability of execution.

Monitoring profiles are also defined for the purpose of simplification.

Abstract: A first sleeve and a second sleeve are put onto the shaft at a predetermined axial distance apart and are pressed radially. The shaft is encapsulated between the first and the second sleeve with a thermoplastic in such a way that a vane body, which has at least one aperture, is formed. The vane body is encapsulated with a sealing compound in such a way that a sealing lip is formed on the vane body at the margins.

Abstract: When determining the amount of a reducing agent solution to be introduced into the exhaust gas of a combustion system, in particular of a diesel engine, for catalytically reducing the nitrogen oxides by the SCR process, the concentration of the reducing agent in the reducing agent solution as well as the parameters characterizing the operating state of the combustion system, the exhaust gas and/or the catalyst are taken into consideration. As a result, the safety margin with respect to a theoretically optimum amount to be introduced that is required to avoid a leakage of reducing agent can be reduced, whereby the conversion rate of the nitrogen oxides is improved.

Abstract: An amplifier output stage is described containing a preliminary stage, a final stage and a control device. The quiescent current that flows through transistors of the final stage is adjusted by the preliminary stage. For this, a current that is proportional to the quiescent current is generated in the control device from which control voltages are derived and controlled. The preliminary stage contains adjustable current sources for adjusting the quiescent current in a final step which are controlled by the control voltages.

The waste-heat steam generator has heating areas connected in a water/steam circuit of a steam turbine. A heat exchanger is provided for cooling a coolant of the gas turbine in order to ensure reliable cooling of the gas turbine even under varied operating conditions. The heat exchanger has a secondary side connected in a second water/steam circuit. The second water/steam circuit is connected to the water/steam circuit of the steam turbine in such a way that it can be shut off. A method is also provided for cooling a coolant of a gas turbine of a gas and steam-turbine plant.

Abstract: A catalytic converter for a small engine and a method for manufacturing the same include a honeycomb body coated with catalytically active material and made from at least partly structured layers of sheet metal with channels for the passage of exhaust gas. In order to reduce manufacturing costs, the honeycomb body is placed in a silencer housing disposed in the proximity of the engine, in such a way that at least a predominant portion of exhaust gas of the small engine has to flow through the honeycomb body. The honeycomb body is a layered, wound or folded stack of sheet metal layers, which is squeezed into the silencer housing, plastically deforming at least 10% and preferably 20 to 30% of the channels, so that it completely fills at least a partial volume of the housing.

Abstract: The integrated circuit has an activation decoder whose outputs are connected to the inputs of a command decoder. When an activation signal is at a first logic level, the activation decoder produces at its outputs a command supplied to it from command inputs. When the activation signal is at a second logic level, the activation decoder produces a deactivation command at its outputs irrespective of the command supplied to it from the command inputs. The command decoder does not activate any of its outputs when the deactivation command is being supplied to its inputs. The command decoder activates one of its outputs in each case when a different command is supplied to its inputs.
