    CPC classification number: G01L1/08

    Abstract: A DYNAMOMETER COMPRISING A BEAM BALANCE HAVING A MOTOR-DRIVEN FRICTION ROLLER AND A FRICTION WHEEL IN CONTACT THEREWITH, THE WHEEL BEARING VIA A GUIDE BAR AGAINST A RAIL EXTENDING PARALLEL TO THE AXIS OF THE FRICTION ROLLER SO THAT WHEN A LOAD IS APPLIED TO THE DYNAMOMETER THE FRICTION WHEEL IS AXIALLY AND LINEARLY DISPLACED WITH RE-

    SPECT TO FRICTION ROLLER UNTIL A NEW POINT OF BALANCE IS REACHED. THE PARALLEL MOTION OF THE FRICTION ALONGSIDE THE FRICTION ROLLER IS ACHIEVED BY MEANS OF A DRIVE MECHANISM CONSISTING OF ARTICULATED LEVERS.

    Abstract: 1, 244, 790. Weighing apparatus; dynamometers. W. HAACK. Nov.13, 1969 [Dec. 12, 1968], No.55544/69. Heading G1W. An automatic force or weighing balance comprises a motor driven friction gear adapted to adjust the position of a rider weight of the balance, one member 6 of the gear being in frictional contact with a second member 21 which is longitudinally displaceable with respect to the member 6 in proportion to the applied force or weight, the second member being mounted on an articulated lever mechanism 11, 14 and being linearly displaceable. The member 6 consists of a roller mounted on a balance beam 1 and continuously rotated, during the measuring of a force or weighing of a load applied at 5, by a motor 8. The levers 11, 14 are provided with counterweights 12, 17 which are adjusted so that the centre of gravity of the lever system lies on the axle 10 of the lever 11. The member 21, which comprises a friction wheel provided with an arm 22 having a roller 24 adapted to run on a guide rail 25, is mounted on an axle 16 so that when the beam 1 tilts due to the application of a load at 5, the relative pivoting between the members 6 and 21 causes the roller 6 to longitudinally displace the wheel 21 until the balance condition is restored. Modifications are described in which the wheel 21 engages the upper surface of the roller 6 and the levers lie in a plane inclined to the vertical and in which the roller 24 engages the lower side of the guide rail 25.

    Abstract: A manually operable balance has only a single operating member (14) which can be rotated into two positions. In one position (arrow 36), a rapid motion is switched on and displaces the sliding weight (8) very rapidly via a recirculating ball screw. In the other axial position of the setting knob (14) (arrow 48), a reduction gear (20, 21, 22, 24) takes effect and the sliding weight (8) is displaced more slowly. An indicator device has a counter with two groups of number rollers. Between the roller groups is located a planetary gear having two movement inputs and one movement output. The latter is connected to the thousands roller which is rotated directly by the planetary gear via a secondary shaft (31). A main shaft (34) rotates simultaneously and rotates the units roller, by which the tens roller and by this, in turn, the hundreds roller are advanced. In the number position 999, an actuating pin overrides the planetary gear for the thousands roller. The single manual-operation knob (14) can be rotated in both directions. The balanced state can be found in both directions of rotation.

    Abstract: The poise of weighing apparatus is displaced by driving means if the weighing beam is not in the equilibrium position. A very small working force is sufficient to displace the poise because, in an embodiment in which the poise is guided so as to slide along a shaft, permanent relative rotation is maintained between poise and shaft, even in the equilibrium position of the poise. Either the shaft or the poise is constantly rotated. In an alternative embodiment, the poise together with at least one shaft forms one unit which is slidably and rotatably supported in bearing bushes, either the unit or the bearing bushes once again constantly rotated even when the driving means no longer produce any displacement of the poise.
