摘要： The method and apparatus herein described relate to the indirect measuring of thermal energy supplied to a number of user stations, for instance to all the apartments of a single building or to many buildings or the like. A temperature sensor with a voltage frequency converter provides an electric signal with a frequency which varies according to the temperature of the thermal carrier fluid. An electronic circuit processes the temperature signal through a variable multiplier which is set by respective multiplexed heat transfer ratings of the corresponding stations to produce a series of impulse trains corresponding to thermal energy consumed by the corresponding stations. Multiplexed counting devices, controlled by demand signals corresponding to fluid flow in the respective stations, receive the respective pulse trains to produce readings of the thermal energy consumed by the corresponding stations.

摘要： A flap valve for controlling a gas flow has an elastically deformable valve tube that conveys the gas flow and having a valve flap that is disposed in the valve tube for movement between an open position and a closed position by a flap shaft that can be driven in order to adjust the valve flap and which is disposed at an acute angle in relation to the valve tube axis, to which shaft the valve flap is fastened so that in the closed position of the valve flap, the flap normal encloses an acute angle with the valve tube axis, in order to assure only a slight amount of leakage in the closed position of the valve flap and a low opening torque, the outer contour of the valve flap is approximately oval in shape. Preferably, the outer contour is embodied as an ellipse.

摘要： In the direct measurement of thermal energy transferred in heating or air conditioning installations, the difference between voltages from outflow and return flow temperature sensors is integrated during a first timing period and then discharged during a second timing period with a constant current to operate a gate passing a number of pulses proportional to the voltage difference. The first and second timing periods are initiated by impulses from a volume flow sensor. During non-timing-period intervals a reference voltage capacitance is set by integrating circuit feedback.In collection of data from a plurality of thermal energy transfer meters, inputs from the meters are scanned at rates greatly exceeding the pulse frequencies to increment or decrement the count in digital filter stages of corresponding pairs of counters depending upon whether sensed voltage levels are opposite or equal to the last accepted voltage level as recorded in a most significant stage of the digital filter.

摘要： The invention relates to a circuit arrangement for the dynamic control of ceramic solid-state actuators, such as piezotranslators with energy recovery by means of magnetic intermediate stores and/or storage capacitors as well as by clocked switches. For achieving a predetermined linear voltage characteristic at the piezotranslator, according to the invention, a single inductive intermediate store is arranged in the secondary circuit, which is connected in series with the piezotranslator, and the secondary circuit is designed as a half-bridge. The switches provided in the respective half-bridge are controlled at a high cycle or switching frequency by an external controller, with the series connection of piezotranslator and inductive intermediate store furthermore carrying a superimposed bridge direct current in order to ensure the desired charging of the capacitance of the piezotranslator, on the one hand, and to optimize the energy recovery, on the other hand.

摘要： In a flap valve for controlling a gas flow, with a valve tube that conveys the gas flow and a valve flap, which is disposed in the valve tube, is non-rotatably supported on an adjustable flap shaft, and can be pivoted between an open position that maximally unblocks the tube cross section and a closed position that blocks the tube cross section, in order to produce a high degree of tightness of the flap valve with the least possible torque, the tube end of the valve tube is inclined so that the circumferential tube edge is essentially disposed in a plane extending at an acute angle in relation to the tube axis. The valve flap has an approximately elliptical outer contour and is disposed in the valve tube at or near the inclined tube end so that its tube normal encloses an acute angle with the tube axis. The valve flap and/or the valve tube may be totally or partially embodied so that they can be elastically deformed and/or tilted.

摘要： A sensor controlled leveling device comprises an attitude detector and/or a laser sensor. In order to create a sensor controlled leveling device with which a desired relative attitude may be automatically set and held the attitude detector has a float which is supported and pivoted in a central part. The laser sensor comprises a zero point recognition means whose output is connected with electronic processing circuitry for at least one servo drive. Using the control unit it is possible for the drive to be operated in a direction opposing a relative change in setting of the laser sensor in relation to a reference plane as swept out by a laser generator so as to correct deviation of the laser sensor from the reference plane.
