Abstract: A dynamometer comprising a pair of similar leaf springs (4 and 5), lying in approximately the same plane, and at least one additional leaf spring (24). The outer part of the additional leaf spring (24) and any other supplementary leaf springs (6, 7, 19, and 20) replacing the single leaf spring and being fastened to the frame (1) and the inner part being fstened to the middle block (8). The leaf springs (6, 7, and 24) lie in a plane approximately parallel to that of the first pair of leaf springs (4 and 5), while the supplementary leaf springs (19 and 20) lie in the same plane as the first pair of leaf springs (4 and 5). An elastic rod (9 and 10) is attached to the middle of each of the leaf springs (4 and 5), respectively, and a force-measuring device (11) is located between these rods. The force being measured is exerted perpendicularly to the planes of the leaf springs (4 through 7, 19, 20, and 24) on the middle block (8) as a compressive or tractive force, and the middle block is displaced in a parallel direction by the leaf springs. At the same time, the rods (9 and 10) are either spread apart or forced closer together, and the force-measuring device (11) is affected accordingly.

Abstract: A balance, which is virtually insensitive to angular deviation and to the presence of additional accelerations of the base, has two dynamometers (2, 3) each having a parallel guide (26). The parallel guides are mutually parallel and their degree of freedom coincides with the direction of gravitational acceleration when the balance is horizontal. The dynamometer (2) measures the weight (M) of the object to be weighed, and the dynamometer (3) measures that of a reference mass (8, 22,24). The balance also has a computer (4) which, from the signals emitted by the two dynamometers (2,3), accurately determines the mass of the object to be weighed independently of the angular deviation of the instantaneous total acceleration. During calibration, which can be carried out only by the manufacturer, the dynamometer (3) determines the weight R.sub.1, R.sub.2 of the reference mass (8, 22, 24) at two different inclinations of the balance and the dynamometer (2) determines the weight (N.sub.1, N.sub.2) of the empty balance pan (18) and the total weight (m.sub.1 , M.sub.2) using a known standard mass. After appropriate processing, the above-mentioned values and the parameters (s, S.sub.1, P, QR.sub.1, N.sub.1) derived therefrom are stored in the read-only memory (30) of the computer (4). The true mass is then determined from the instantaneous values of the weights (M, R) and the stored quantities.

Abstract: A mass and force meter with a frame, a load-support and a measuring system, wherein the mass or force to be measured acts indirectly on the tension of two transversally vibrating, pre-loaded strings excited by electronic means, so that the resultant frequency changes serve for calculating the magnitude of said mass or force in a computing device. Both strings, a first transmission element for the transmission of a pre-loading force and a second transmission element for the transmission of a force depending on the load to be measured are fixed to a force distributor. The force distributor is guided in a statically determined way relatively to the frame by means of the two strings, and by means of at least one guide with forming the first transmission element respect to the pre-loading force and to the force depending on the load to be measured, said guide being elastic and under a bending pre-tension and able to transmit moments, so that it generates the pre-load of the strings and transmits it to the force distributor.

Abstract: The bulk material, the amount o which is to be determined through second-integration or time-integration, passes over a top chute onto a bottom chute which is disposed at a tilt angle and defines the velocity of the bulk material. The bottom chute channels the bulk material to a slide which has the same angle of tilt as the bottom chute. The weight components of the amounts of bulk material on the slide acting orthogonally along the direction of the slide are determined by a load-sensing device. After passing down the slide the bulk material impacts a vertically arranged deflector plate which is rigidly connected to a connecting plate, with the deflector plate at that point generating a force through its change in its pulse action which is determined by a second load-sensing device. The second load-sensing device only measures the horizontal components of this change in pulse action, and, like the initial load-sensing device, is either parallel channelled or provided with parallel channelling. Both load-sensing devices are connected via lines to a computer which contains the evaluation formula and all relevant correction parameters stored in its memory. Both of the chutes and the load-sensing devices are supported by a frame. Once having been weighed, the bulk material falls into a funnel.

Abstract: The load measuring device according to the invention comprises at least three identical force meters that together support the frame (2) and, for example, are supported on the chassis (1) of a truck. The individual force meter comprises a flexural spring (10) as primary spring of an elastic reduction, and a further flexural spring (17) as secondary spring of the elastic reduction. A force transducer (18) with at least one perpendicularly oscillating cord is inserted between the center section (15) of the flexural spring (10) and the center of the flexural spring (17); this force transducer (18) measures the reduced force flow subject to the firmness of the flexural springs (10 and 17). The outside sections (13) of the flexural spring (10), for example, are connected to the frame (2), and the center section (15), for example, is connected to the chassis (1). The flexural spring (10) in the compression direction has a flat inertia ellipse, therefore in the transverse direction is substantially firmer than in the compression direction, and in contrast is relatively torsionally soft with regard to torques in the horizontal axis.

Abstract: A mass and force meter comprising a frame, a load support, a digital evaluation and display device and two electrically-excited, transversely-vibrating, pre-tensioned strings each having one end fixed to the frame. The other ends of the strings are connected to a force distributor, and first and second transmission elements are provided for transmitting to the force distributor a pre-tensioning force and a force which depends on the load to be measured. One end of each of the transmission elements is fixed to the force distributor and the other ends are connected to the respective pre-tensioning and load forces. A guide member having one end connected to the frame and the other end connected to the force distributor acts together with the strings to guide the force distributor in a statically defined manner relative to the frame with respect to the pre-tensioning force and the force established by the load to be measured. Means are further provided for applying to the evaluation display device the resultant frequency variations caused by application of load to the strings thereby permitting measurement and display of the magnitude of the measured load.

Abstract: The parallel guide of an elastic force reducing dynamometer comprises a frame secured to a base plate, two essentially parallel plates, a load carrier, and four elastic tie joints. The load carrier supports a balance pan for receiving weights. A load-carrying element is clamped between the upper end of the load carrier and the lower end of the frame. Compressive force exerted on the load carrier is converted into an electric signal. The parallel guide is manufactured from a single piece, for example by profile extrusion or wire erosion. In an alternate embodiment of the invention, the load-carrying element is clamped between the lower end of the load carrier and the upper end of the frame. Tensile force exerted on the load carrier is converted into an electric signal.
