Abstract: A multistage multi-lane singulator conveyor system for separating side by side packages in stages. A first high friction surface conveying moving articles forward is adjacent a second low friction conveying lane in lateral flow communication having both forward and lateral conveying forces urging parcels forward and away from the first conveying lane, wherein the second conveying lane can be level or transversely inclined and angled upward in lateral flow communication with a third high friction surface conveying surface. Controlling residence time and forward and lateral movement of articles by assembling high friction surface conveying lanes and low friction surface conveying lanes in an end to end and/or lateral arrangement in flow communication with one another and/or shifting articles moving forward and laterally by staggering the high friction conveying surfaces and low friction conveying surfaces and adjusting the width by adjusting the number of high friction conveying surfaces adjacent one another.

Abstract: A multistage multi-lane singulator conveyor system for separating side by side packages in stages. A first conveying lane having a high friction surface is combined with a second conveying lane adjacent thereto in lateral flow communication therewith having a lower friction conveying surface including both forward and lateral conveying forces urging parcels forward and away from the first conveying lane. The conveying surface of the second conveying lane may form an inclined plane extending above an inner lateral receiving edge of an adjacent third conveying lane having a high friction surface in lateral flow communication therewith. Each of the high friction conveying lanes may utilize a plurality of narrow belts to vary the area of the high friction surface.

Abstract: A cutting head of a waterjet cutting system is provided having an environment control device and a measurement device. The environment control device is positioned to act on a surface of a workpiece at least during a measurement operation to establish a measurement area on the surface of the workpiece substantially unobstructed by fluid. The measurement device is positioned to selectively obtain information from within the measurement area indicative of a position of the cutting head relative to the workpiece. A control system is further provided and operable to position the cutting head relative to the workpiece at a standoff distance based at least in part on the information indicative of the position of the cutting head relative to the workpiece obtained by the measurement device. A method of operating a waterjet cutting system is also provided.

Abstract: A large volume preconcentrator device for concentrating analytes. A housing accepts an analyte vapor flow, and a plurality of collection surfaces are disposed within the housing. A selectively actuatable heater is disposed on each of the plurality of collection surfaces. At least one selectively actuatable damper is disposed within the housing for selectively restricting a collection flow.
