Abstract: A mounting (28) for a side panel (26) of a weighing machine (10) has two rails (30, 32) which lie opposite one another and extend substantially parallel to each other. The side panel (26) is guided between the rails and thereby moves between a closed position and an open position. A stop (46) on the first rail (30) co-operates with the side panel (26), such that the completely open position is defined, and the second opposite rail (32) lies opposite the first rail (30) with such a spacing that the side panel (26), when being located in the open position, can be moved away by lifting of the rear edge (29) of the side panel (26) over the stop (46), but the opposing front edge (27) of the side panel (26) cannot be lifted or can only be lifted insignificantly.

Abstract: In an integrating A/D converter, first and second reference voltage inputs (18, 20) alternatingly connect through a reference voltage switch (16, 16?) via a first reference resistor (Rref) to an inverting input (122) of an integrator (12). A comparator (22) connected downstream of the integrator (12) compares a test voltage applied to its test voltage input (221) with a comparator reference voltage applied to its reference voltage input (222). This input (221) is connected to- the output (126) of the integrator (12). A control device (40) actuates the first reference voltage switch (16, 16?) in a pulsed manner and measures the time intervals between the individual switching processes. An inverter (24) inverting a measuring voltage (UM) and a first heating resistor (RMH) coupled thermally with a measuring resistor (RM), are connected in series between the measuring voltage input (14) and the output of the first reference voltage switch (16, 16?).

Abstract: A balance having at least one adjusting device (2, . . . ) having a drive, wherein the drive of the adjusting device is configured as a fluidic drive (4, . . . ), to which pressure can be applied by a pressure source disposed outside the scales via a pressure connection.

Abstract: A pinch valve with an axially extending tube guide, a clamping jaw (12) which displaces perpendicularly to the axial direction, and an abutment (12; 21) which is opposite the clamping jaw in the jaw displacement direction. The tube guide, the clamping jaw and the abutment are disposed relative to one another such that a flexible tube (18) laid in the tube guide (18) is pinched by the advancing clamping jaw against the abutment. The clamping jaw has a displaceable support element (14) and two claws (16a, 16b) located opposite one another and engaging around the tube guide at least in some regions. The claws are articulated on the support element (14) by the respective rear ends thereof such as to pivot about pivot pins oriented parallel to the axial direction and forming a mouth which opens as the clamping jaw advances and closes as the clamping jaw retracts.

Abstract: Force plate (1) having a plate-shaped carrier (2) which, when arranged vertically, has an upper carrier section (3) at the top in the vertical direction and a lower carrier section (4) at the bottom in the vertical direction. A first end carrier section (5) is connected, on the one hand, to the upper carrier section (3) via a vertical rod (7) and, on the other hand, to the lower carrier section (4) via a horizontally oriented spring element (6). That end of the lower carrier section (4) which faces away from the first end carrier section (5) is connected to the upper carrier section (3) via a horizontal rod (8). A second end carrier section (15) connects the horizontal rod (8) to the lower carrier section (4) via a vertically arranged spring element (16).

Abstract: An optoelectronic inclination sensor determines the inclination of a reference plane relative to the horizontal. A sensor body has a liquid layer, the free surface of which represents a horizon that can be inclined relative to the reference plane, forming an optical boundary to the adjacent medium. A light source disposed below the liquid layer emits a light beam onto the boundary. An optical sensor surface below the liquid layer detects the light beam reflected by the boundary. An analysis unit determines the inclination of the reference plane as a function of the amount of light received by the sensor surface. A deflecting element for deflecting or initially totally reflecting the beam is disposed between the source and the liquid layer. The beam is inclined as a result of said deflection or initial total reflection. A second total reflection occurs at the boundary in both the inclined and non-inclined orientation.

Abstract: A filling system has a filling apparatus (200) and a container arrangement inserted into the filling apparatus. A main line includes a feed line (102), connected to a supply container (304), and a trunk line (104), connected linearly downstream of the feed line (102). Outside the trunk line (104), at a branching point (114), a branch line (116) branches from the main line (102) to a compressed-gas source (306), and the main line (102) and the branch line (116), on that side of the branching point (114) which is directed away from the trunk line, pass through a double-valve arrangement (214) having two hose-clamping valves (214a, 214b) controlled oppositely to one another.

Abstract: A precision balance provided with a windshield having at least one wall element (2, 10, 12, 20, 24), which is provided with an electrically conductive coating (62), and having an electrical connection (66) for the coating. An electrical test device (68) is additionally provided, which is integrated into the precision balance and with which it is possible to check whether the coating (62) is connected to the electrical connection (66).
