Abstract: The present invention is a rotary indexing table driven by an induction motor. The rotary indexing table includes a rotatable work supporting platform, an AC induction motor including a motor shaft coupled to the rotatable work supporting platform; and a controller operatively coupled to the AC induction motor. The AC induction motor is equipped with a high resolution positional feedback device. The high-resolution positional feedback device may be an encoder or a resolver. The controller is configured to drive the AC induction motor in a direct drive manner. The high-resolution positional feedback device is operatively coupled to the controller, and the controller is configured to filter a signal provided by the high-resolution positional feedback device. The signal provided by the high-resolution positional feedback device may be a square wave or a sine wave. The present invention is also directed to a method precisely driving and positioning a rotary indexing table.

Abstract: A V-band clamp that includes an annular band having an inner surface and an outer surface. A latch assembly is attached to the outer surface of the band for attaching objects together. A plurality of insert segments are attached to the inner surface of the band, wherein each segment includes a contour edge for preventing damage to objects being joined together during installation of the V-band clamp.
