    Abstract: A flexure or bending coupling member (10) is disclosed for precision scales and the like, including a pair of clamping end portions (12) joined with a central bar portion (18) via a pair of flexure portions (15), characterized in that the bar portion is arranged normal to the plane containing the end portions and the bending axes of the flexure portions. The central bar portion is connected with the flexure portions (15) via twisted portions (20) rotated 90.degree. about the longitudinal axis of the flexure coupling member, thereby affording improved resilience in the lateral direction and greater insensitivity regarding dimensional inaccuracies at the clamping locations and/or with respect to temperature variations.

    Abstract: Scale in which force applied to a platform is transmitted to a transfer lever arm through flexure plates. In one embodiment, the transfer arm is connected to a load cell which produces an electrical signal which actuates digital means to provide a digital indication of the weight of an object on the platform. In other embodiments the transfer arm bears against a hydraulic load cell which is connected to a pressure gauge or digital display means for indicating the weight of an object on the platform.

    Abstract: A weigh scale apparatus in which forces caused by the applied load are transformed into moments of opposite sense and applied to opposite ends of a substantially rigid beam. Deflection of the beam is measured by centrally disposed strain gage resistors to produce an electrical signal quantity proportional to the applied load. The conversion of applied load to moments of opposite sense is accomplished by a pair of spaced parallel pivot members which are suspended by straps between the load receiving pan and the base such that the pivots tend to rotate in opposite directions. The beam is mechanically connected between the pivots such that it is subjected to the bending moment over substantially its entire length. A split scale device is provided by a composite pan, one portion of which is connected to the pivots directly and another portion of which is connected to the pivots through long lever arms to provide moment multiplication. A vibrator device for dithering the pivots is provided. .Iadd.

    Abstract: This inventive scale consists of a frame (2), a platform (3) parallel and perpendicular to the frame (2), a load lifter (5) and a level mechanism consisting of at least one arm (1). The lever mechanism transmits the load from the platform (3) to the load lifter (5) and is connected to the frame (2), the platform (3) and the load lifter (5) by means of couplings (10, 13, and 15). The lever mechanism, consisting of at least one arm (1), has a flexible connector at each end and one in the middle (7, 8, and 9). The end connectors (7 and 9) are attached to the platform (3) and the load lifter (5) by means of pins (10 and 15), respectively. The middle connector (8) is attached to the frame (2) by means of two swivel couplings (13).
