Abstract: The invention relates to a method to determine the volume of small, spherical moving objects in which the objects move through the optical path of a photo electric sensor that comprises at least one light beam transmitter and one light beam receiver, and the change in the light intensity at the light beam receiver caused by objects passing through the optical path is registered and converted into an electrical measurement signal by means of an evaluation unit. The invention is distinguished by the fact that before a measurement process, the amplitude of the electric measurement signal is calibrated to a previously determined average standard volume of the objects and during the measurement process, the volume of each measured object is determined using the change in amplitude of the measurement signal.

Abstract: To provide a measuring method on an electric motor with a rotor and a stator for determining the fly height and/or axial play, the rotor being mounted, and in particular fluid-mounted, on the stator, with which method the axial position of the rotor in relation to the stator can be determined with high levels of accuracy and reproducibility, it is provided that the electric motor is operated at a defined measuring speed, at which the rotor is in a specific axial position in relation to the stator, with this relative axial position being determined in that the rotor is brought in a defined manner, with the motor at a standstill, into a first stop position in relation to the stator, in that the rotor is brought in a defined manner, with the motor at a standstill, into a second stop position in relation to the stator, lying opposite the first stop position, and in that the relative axial position between the rotor and the stator is respectively measured in the two stop positions.

Abstract: A guide rod assembly for a Jacquard loom is described which is narrower (10 mm or less), instead of 13 mm of conventional guide rods. This reduction in width is attained reducing the overall height of the magnet system integrated in the guide rod. The magnet system has a support member in the form of an iron core with an elongated or oval cross-section, with an excitation coil wound around the iron core. Pole strips are in contact with both front faces of the iron core. The respective top surfaces of the pole strips are spaced apart by less than 13 mm.
