Abstract: A worm centrifuge system is disclosed wherein a rotatably supported centrifuge drum is provided together with a conveyor worm rotatably supported within the drum. A drive motor is provided for the drum and a separate drive motor is provided for the worm. A centrifuge drum and conveyor worm are normally operated at different RPMs. The conveyor worm is driven by one of the motors through a planetary gear and a housing of the planetary gear is connected to the centrifuge drum. The other drive motor connects with the housing of the planetary gear by a belt system. A switchable coupling is provided to connect the input of the planetary gear to its housing during start-up and then selectively to disengage the housing from the input of the planetary gear after operating speed is attained and the other drive motor is energized. The maximum energy requirements for each of the drive motors is reduced, thereby reducing cost.

Abstract: A method and apparatus for smoothing local unevenness from the surface of bar material, such as anode bars, consisting of clamping the bar rigidly against a supporting frame and moving a smoothing device along the bar, said smoothing device maintained in continued contact with the bar by means of rollers pushing against opposed parallel faces of the bar. The rollers allow the smoothing device to move according to the general contour of the bar, so that only local unevenness is removed, and excessive smoothing due to curvature in the overall bar length is eliminated.

Abstract: An apparatus is disclosed for the determination of particle size distribution of a granular material within a measuring channel. The measuring channel has radiation permeable side walls and a granular material is spread out through the measuring channel by a sifting air current in accordance with grain size. A scanning apparatus is movable external to the measuring channel and includes a frame on which is mounted a radiation transmitter and a radiation receiver lying opposite the transmitter. A measuring beam from the transmitter scans through a measuring zone of the measuring channel. The measuring frame is of closed-loop construction and surrounds the measurement channel. With such construction, the frame is not subject to vibration particularly when reciprocated in order to cause scanning movement of the measuring beam.
