Abstract: Adaptable clevis kits may be used when calibrating crane scales, dynamometers and tension links for force calibration laboratories. An adaptable clevis kit may include one set of devises (one pair) with multiple sets of pins with different diameters. With this kit, the same set of devises may be used for calibrating several models of instruments. For each instrument, the pin may be designed with the same diameter that the manufacturer originally made the equipment and reported on its specification sheets. With this method, the error due to difference in pin sizes is eliminated, and the laboratory may save the cost of purchasing dozens of different devises. The adaptable clevis kits may also be provided with a guiding table that help the user find the right size pin for the instrument being calibrated based on the manufacturer's original design.

Abstract: A micro-gripper includes a support to which are articulated fingers and an actuating diaphragm, adjusting the spacing of the fingers. The support being circular, the fingers may be arranged in any number around it, and the diaphragm delimits a chamber with the support assembled to an equipment for distributing fluids, the pressure of which elastically deforms the diaphragm and controls a simultaneous movement of variations in spacings of the fingers. If the diaphragm is conical and the fingers link up all around, an independence of the movements of the fingers remains.
