摘要： A force-reduction mechanism for a force-measuring device is made of a monolithic material block (1) and has a stationary support (8), a plurality of levers (9, 15, 17), and coupling elements (11, 14, 16) connecting the levers. The fulcrum (10a) of at least one lever (17) is movable in relation to the stationary support (8). A movable fulcrum (10a) can, e.g., be located on a preceding lever (9), so that the fulcrum (10a) shares the motion of the preceding lever (9). The concept of a movable fulcrum allows a more space-efficient design of the mechanism.

摘要： A precision balance includes a load receiving member, a balance housing and a measuring cell connected to the load receiving member and the balance housing. The measuring cell is arranged between side portions of an intermediate support member and is fastened thereto in a frictionally engaging manner. The contact surfaces between the intermediate support member and the measuring cell can be produced with narrow tolerances in a simple manner, so that a screw connection between the intermediate support member and the measuring cell does not introduce significant distorting forces into the measuring cell. The measuring cell can be adjusted with the intermediate support member before being mounted in the balance housing. The later mounting of the measuring cell does not influence the adjustment because the intermediate arrangement of the intermediate support member disconnects the measuring cell from inaccuracies of the fastening surfaces on the housing.

摘要： The invention is a load cell for the measurement of force, independent of displacement, created by means such as weight, acceleration, pressure, and the like. The load cell has a beam structure with beams positioned parallel to each other in at least one plane. Generally, these parallel beams are attached to a stationary base and have sensing means attached between the two beams. In operation, deflection of one beam creates a response in the sensing means due to the relative action or deflection in the second beam.

摘要： The rod-shaped load cell consists of a guide section (1), which is subdivided into a frame (6) and a load-bearing element (7), and two parallel, rigid plates (8) connecting the two cited elements. Plates (8) are connected to both frame (6) and load-bearing element (7) by band-shaped flexural joints (9) which extend across the overall length of guide section (1). The load cell rests via frame (6) upon two feet (2) located outermost on rod-shaped guide section (1). The platform (5) rests upon two mounting elements (3) also located outermost on guide section (1), with the mounting elements (3) acting on load-bearing element (7). A force sensor (4) is diagonally installed at half the length of guide section (1). When platform (5) is loaded, tensile force acts upon force sensor (4) (see FIG. 1).

摘要： It is disclosed for a balance with a scale on top based on the principle of the electromagnetic compensation of force with a system carrier fixed to the housing, with a load receiver, with two guide rods which connect the load receiver to the system carrier in a vertically movable direction as parallel guide, whereby the stem carrier, the two guide rods and the load receiver are designed as a one-piece casting, with a translation lever and with a coupling element between load receiver and translation lever, whereby the force from the load receiver corresponding to the mass of the weighed material is transferred via the coupling element to the shorter lever arm of the translation lever and the coil of the electromagnetic compensation of force is fastened to the longer lever arm of the translation lever that the system carrier comprise lateral projections which extend into the area between the guide rod arms. This achieves a distinct reinforcement of the system carrier without having to increase the outer dimensions of the system. The stability of the entire system can be further increased by means of further reinforcement measures in the lad receiver and in the guide rod arms.

摘要： The hospital bed is provided with a scale assembly which is incorporated into the bed between the bed support frame and patient supporting section. The links which connect the patient support section to the bed support frame are connected to the load frame of the scale assembly so that weighing may occur in any position of the patient support section. The scale assembly is connected to the transverse beams of the bed support frame in a depending manner via bolts. Linear variable differential transformers are used to obtain read-out signals for the displacement of the load frame as a measure of the weight on the load frame.

摘要： The specification discloses a balance for measuring a load. This balance uses an electronic or optical transducer and a parallelogram support for the load to be weighed. The parallelogram linkage uses one or more torsion bars to resiliently support the load, wherein the deflection of the parallelogram is proportional to the weight of the load. When used with a capacitance transducer, the parallelogram linkage also enables the capacitor plates to remain parallel to one another as the parallelogram is loading, thereby producing a signal that can be electronically processed to provide a liner digital read out signal on indication of weight. Electronic data processing means as provided to calculate and display on indication of weight and/or volume. An optional opitcal indicator means is also disclosed to provide an optical reading of the weight of the load.

摘要： In an analytical balance with a pan and a four-bar mechanism which keeps the balance pan parallel horizontally during its vertical travel, the one vertical side of which is held fast to the housing, the other vertical side of which, in the form of a coupling piece, carries an extension which receives the pan, and both horizontal sides of which are connected in an articulated manner by an upper and a lower rod to the vertical sides, whereby the four-bar mechanism is loaded by the restoring force of a load converter, the extension (16) which receives the pan (17) is L-shaped, the horizontal L-shank (pan arm) (16") carries the pan (17) rigidly connected to its free end and the vertical L-shank (bearing arm) (16') is mounted on the bar (18'") of a U-shaped arm bearing (18) which projects above and below over the vertically movable end (9) of the four-bar mechanism (5, 6, 7, 8, 9) with its two horizontal U-shanks (18, 18") in the rod planes and is rigidly fastened to it in two vertically superposed bearings (118'). Such a construction avoids the introduction of damaging torques from the extension (16) and the balance pan (17) into the sensitive parallel guide (5, 6, 7, 8, 9).

摘要： A weighing system includes a weighing pan connected to a rigid armature by a mechanical filter constraining the armature to motion along a reference axis with respect to a housing and damping out transient forces along this axis resulting from the placement of objects on the pan. The mechanical filter includes spring and damping elements that provide a low-pass filter, that is, one that efficiently and quickly eliminates high frequency oscillations. In one form, the mechanical filter couples the pan to the armature. Because of this connection, friction in the mechanical filter does not result in frictional errors in the weighing measurement. In another form, a mechanical linkage couples the armature to the housing. A force transducer, comprising a pair of complementary opposed surfaces having a mutual separation which is related to the force across the transducer, is coupled between the armature and the housing. Coupled to the transducer is a position sensor which generates a signal representative of the separation between the complementary opposed surfaces of the transducer.

摘要： An improved weighing scale comprises a base support for a plurality of load cells, a resilient load decoupling member for each load cell, and a platform. The resilient load decoupling member allows each load cell to be decoupled from non-vertical forces, but still provides positioning and self-centering means. The load cells provide an output signal indicative of the applied weight on the platform.
