Abstract: A material handling system has a shuttle car attached by an extension element either directly to a supply car or to a staging car attached to a supply car. An object manipulator moves an object into place for acquisition by the shuttle car which is brought into position by retraction of the extension element. The extension element extends and moves the shuttle car away to draw the object most of the way from the staging car. A second object manipulator opposite to the shuttle engages the object before the object is pulled completely from the supply car. The shuttle car and the second manipulator lower the object. Objects may also be retrieved and placed on the supply car. In some embodiments, a track on the staging and supply cars may allow a manipulator to travel along the cars to acquire objects.

Abstract: A vehicle supported mine item positioning apparatus for placing, for example, heavy mining conveyor belt items such as roller assemblies, conveyor frame side rails, frame sections or the like in precise positions for attachment to other conveyor structure, wherein the vehicle can get into cramped quarters in the mine alongside the conveyor and extend, retract, rotate and further manipulate an item pick-up crane mounted on the vehicle, whereby the crane with item pick-up means mounted on an end thereof can pick up and place, e.g., a roller assembly in a precise position and posture on a conveyor frame for making said attachment, and further in a preferred embodiment, the apparatus is provided with second crane means for lifting a moving conveyor belt off of a roller assembly for replacement of said assembly with or without stopping the belt, whereby worker lifting and manipulation of heavy roller assemblies or other heavy mining structures is eliminated.

Abstract: An extendible belt conveyor system for a mine. Cars carrying conveyor rollers are part of a main conveyor. When the conveyor needs to be expanded, the individual cars may be extended to extend the framework for the belt. The wheels on the cars may be both elevated and rotated for positioning. A low profile structure may carry a separate conveyor which can fit below the profile of the cars and thus further extend the conveyor. The low profile conveyor can have an elevating head drive mounted thereon which is slidable and can be fixed in a position as the framework is moved forward. This arrangement can be used also in other situations as for dumping refuse in a pile.

Abstract: The invention provides an apparatus and method for performing a process on a substrate. At least two types of structures may be used to provide a flow path for a substrate so that the substrate may be moved from one processing or loading position to another. The first is a conveyor. The second is a track. The flow path may be a closed continuous loop. Each processing island has a valve for introduction and extraction of the substrate into and out of an interior of the island. The processing island may include load locks, and may include in conjunction therewith an inspection station, a CVD chamber, a PECVD chamber, a PVD chamber, a post-anneal chamber, a cleaning chamber, a descumming chamber, an etch chamber, or a combination of such chambers.

Abstract: A mobile and elevatable train is used in an underground mine to extend, or shorten, a roof-mounted conveyor system. A train is comprised of a plurality of cars, each of which has independent jacks adapted to raise, or lower, each car with respect to the roof. The plurality of cars is linked together by a mechanism which allows the cars to travel together, yet allows them to pivot with respect to another and also assume different elevations with respect to another. Each one of the plurality of cars carries at least one detachable roller structure which is elevated to the position it should have in the conveyor system, after the roof supports have been attached. Each car may also carry at least one permanently attached roller structure so that the mobile and elevatable train can temporary function as the support for a moving conveyor belt, prior to its next move. The mobile and elevatable train is equally adapted to either an advancing, or retreating, belt line.
