20100187755	ANGLED PRESSURE ROLL USED WITH VACUUM BELTS - An apparatus comprises a belt and a pressure roll contacting the belt. The pressure roll comprises at least two roll segments connected to a common axle and contacting the belt. The roll segments are offset from one another along the belt.	07-29-2010
20100320677	SEGMENTED RIGID PLATE BELT TRANSPORT WITH A HIGH MOTION QUALITY DRIVE MECHANISM - A vacuum transport includes a segmented, rigid or solid articulated belt combined with a vacuum plenum in each segment of the belt. Using a rigid segmented belt with a vacuum plenum connected to each segmented belt section eliminates ordinarily encountered drag friction in conventional vacuum transports by reducing the force necessary to move the belt with media thereon while simultaneously improving the motion quality of the move by driving the articulated rigid belt from the top side of the belt in a flat section.	12-23-2010

20090309299	SHEET TRANSPORT ROLLER SYSTEM - A sheet transport roller system and methods for reducing sheet skew using a sheet transport roller system are disclosed. A sheet transport roller system for use in a document processing device may include a plurality of idler rollers, a plurality of drive rollers and a load distribution mechanism. Each drive roller may correspond to a corresponding idler roller. The load distribution mechanism may be configured to support the plurality of idler rollers and to equalize normal forces applied by each idler roller towards the corresponding drive roller. The load distribution mechanism may include a center loading spring in contact with the document processing device.	12-17-2009

20100163310	METHOD OF MANUFACTURING AND REPAIRING FIXED-CUTTER DRAG-TYPE ROTARY TOOLS WITH CUTTING CONTROL STRUCTURES - A rotary tool for drilling subterranean material is disclosed. The rotary tool includes a tool body having a distal crown end comprising a circumferential series of raised cutting blades with recessed junk slots therebetween. Cutting elements are located proximate a leading peripheral edge of the raised cutting blades and cutting control structures are located interiorly of the cutting elements at a leading surface of an adjacent junk slot. Cutting control structures are releasably secured to the tool body in the adjacent junk slot whereby a used rotary tool is refurbishable by removing worn cutting control structures without degradation to the tool body and replacing the worn cutting control structures by installing new cutting control structures in the worn cutting control structures' locations.	07-01-2010
