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： In an electromagnetic balance based on the principle of the eletromagnetic compensation of force a weight-proportional counterforce is generated by a current-carrying coil in a permanent magnet system. An arrangement with annular coil with vertical axis and with a permanent magnetic system constructed symmetrically to the central plane of the coil has proven to be advantageous. However, this arrangement results in a relatively great construction height of the balance. In order to decrease this height, the invention suggests that the soft iron pole plate which is usually present between the like poles of the plates of active magnetic material be reduced in its diameter or entirely eliminated and that the coil be allowed to extend into this area between the plates of active magnetic material. This in conjunction with the use of materials having high coercivity makes a very low constructional height possible.

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.

摘要： It is known in high-resolution electronic weighing scales based on the principle of electromagnetic force compensation that the load-dependent development of heat in a coil and a precision resistor can be compensated by sending an additional alternating current through the coil and the precision resistor which is complementarily regulated in its amplitude. In order to regulate the amplitude of this alternating current, the invention proposes a simplified circuit which comprises a highly temperature-dependent resistor, the resistance value of which is set at a fixed theoretical value.

摘要： A filtration or diffusion cell, consisting of adjacent facing support plates and cut diaphragm sections of a semi-permeable diaphragm, for the treating fluids. The support plates are sealed by stringlike or bandlike sealing elements for the separate flow conduction of the fluids. Support plates are provided with channel grooves, for holding the sealing elements. The channel grooves are open toward the plate plane and are provided with perforations through which a sealing material inserted in a flowable state and solidified in the grooves. Several support plates are connected by the sealing material to form a plate holder-like unit, and form seals for separate flow conduction. The support plates are square-shaped, and the front side and the back side of the cut diaphragm sections are subjected to crosswise flow of the fluid. The cut diaphragm sections are supported by grooves and groove crests extending in flow direction of the support plates. The grooves are provided with longitudinally spaced passages leading to the opposite side of the support plates. Flow barriers crossing the grooves under an angle of about 45.degree. bring about a uniform overflowing of the diaphragm surfaces and prevent shortcuts.

This makes it possible to display in a simple manner the relative position at which taring was performed. Still other segments (8, 10') can also be used in an advantageous manner as a scale for the quasi analog display.

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.
