摘要： In a drying balance with scale on top and with a radiation source for heating and drying material to be weighed located on the balance scale, the radiation source (11) is permanently located behind the balance scale (5) and a bent cover (7) which functions as a radiation deflector is movably located over the balance scale (5). This makes the construction lower and a moving of the radiation source (11) with its electric connections is avoided when the balance scale (5) is loaded. Moreover, differently constructed inner surfaces (7') of the cover (17) permit the drying balance to easily adapt to different radiation sources (11) and to different drying tasks.

摘要： Apparatus for measuring weight and force has a load reception part arranged for deflection on a fixed part of a weighing and force-measuring system and includes a compensation coil arrangement situated in a constant magnetic field. At least one position sensor ascertains load-dependent deflections of the load reception part from a predetermined position and feeds a sensor signal to an electric regulator circuit. The regulator circuit regulates the current through the compensation coil arrangement so that the load reception part is returned to its predetermined position. The regulator circuit includes means which impart, alternately, positive and negative values, determined by the loading, to the current flowing through the compensation coil arrangement.

摘要： Electronic weigher apparatus is disclosed which utilizes a plate situated below the weighing scale and above a load receiver which is part of an electronic weight measuring system. The plate is shaped in such a way that thermal air currents generated by the electronic apparatus are carried through a low air resistance path from the interior to the exterior of the weigher casing while a high resistance airflow path prevents air currents from being carried upward from the electronic apparatus to the weighing scale. A collar encircling the scale prevents external air currents from disturbing it during the loading operation.

摘要： The invention is relative to a method of statically (non-multiplexed) actuating a liquid crystal display which comprises several segments and a common back electrode, using a microprocessor which serially outputs the data to be displayed, and using a serial/parallel converter which statically makes the data to be displayed available for each segment of the liquid crystal display. The invention has the task of achieving recognition of functional error as follows: The data to be displayed is outputted approximately every 0.1 second by the microprocessor and the data for the individual segments and for the back electrode is inverted at every second data output. The failure of components then results in a blinking of the particular segment and is conspicuously indicated in this manner. In the case of alternating voltage actuation of the liquid crystal display, it is advantageous if the clock pulse of the alternating voltage actuation is also inverted at every second data output.

摘要： The invention suggests an intermittent mode of operation to reduce the stray power in the coil in a balance based on the principle of the electromagnetic compensation of force. To this end, switching means (21) are provided which can interrupt the current flow through the coil (11) so that when the current flow is interrupted, the movable parts (2-9) of the balance move against one of the stops (24) or (25). These switching means (21) are controlled by the digital signal processing unit (18). In addition storage means (20) are provided within the framework of the digital signal processing unit which store the last-determined weight value for the duration of the interruption of the current flow through the coil.

摘要： A balance having a setting means with which the relative precision of the weighing result is to be determined can be set by the user. The balance then adapts automatically to the set relative precision. This adaptation can occur, e.g., in the number of positions displayed, in the step width in the last particular position, in the selection of the integration time, in the filtering of the measured values in the digital signal processing unit, in the frequency of the taking over of the measured value into the display and/or at the time of the emission of the standstill signal or of the measured value release signal.

摘要： An electric inclination meter is built into a high-resolution electric balance with a measured value receiver, a microprocessor for digital signal processing and with a digital display. This inclination meter compensates the inclination-dependent errors of the balance. The inclination meter can have a movable suspended mass or it can have a container which is partially filled with liquid, thus forming a gas bubble. The positional deviation of the movable elements can be picked up optically or inductively.
