Abstract: The invention is particularly useful for coacting with roller tubes of conveyor apparatus. A cartridge bearing including a stub axle with a tip of greater hardness than the surface circumscribing the aperture receiving the stub axle is inserted into an end of a conveyor roller tube. Along with being electrically conductive, the stub axle can be provided with a damper for reducing vibration. The stub axle engages an electrically conductive stub shaft and moves axially with respect to the stub shaft to operatively interlock with the aperture of the fixed structure. Use of the cartridge bearing provides for the grounding of static charge that can accumulate during operation of conveyor roller tubes.

Abstract: The present invention relates to sliding shoe sorters and methods of using those sorters. One or more pluralities of the shoes are interposed between the conveyors lateral edges and can be orderly advanced in lines. Controllers activate or deactivate the diverters which direct the sliding shoes toward one or more receivers, and the diversion of the shoes can result in the egressing of an item away from the conveyer. The receivers can be provided with rediverters to redirect the shoes toward the interposed sliding shoes. Items advanced by the conveyor may have a code placed about them, and after a code has been placed about the item to be sorted, a paradigm or paradigms responsive to the code can be created to orchestrate activation or deactivation of the diverters and/or the rediverters.
