Abstract: A linear wave motion conveyor is disclosed. A pan defines a conveying surface and a conveying direction. A linear drive mechanism is provided having an elongated thrust bar extending parallel to the conveying direction and a stator portion configured to drive the thrust bar in relation to said stator portion along the conveying direction. A base supporting the linear drive mechanism and the pan is provided. The thrust bar is fixed in relation to one of the base or the pan and the stator portion is fixed in relation to the other of the base or the pan. A controller is in operative communication with the stator portion to control driving of the thrust bar in relation to the stator portion. The controller is configured to cause the stator to drive the thrust bar in conformity with a cyclic pattern of motion along the conveying direction.

Abstract: A relocatable oil sand slurry preparation system is provided for preparing an aqueous oil sand slurry amenable to pipeline conveyance while producing minimum overall rejects, comprising (a) a relocatable rotary digester for slurrying oil sand and water and digesting oil sand lumps to form a pumpable slurry, the rotary digester having a feed end for receiving oil sand and water, a slurrying chamber comprising a plurality of lifters for slurrying the oil sand and water, and a trommel screen end for screening out oversize rejects from the oil sand slurry which falls through the trommel screen; and (b) a relocatable rejects recirculation unit operably associated with the rotary digester for receiving oversize rejects and delivering the rejects back to the rotary digester for further digestion. In a preferred body, relocatable oil sand slurry preparation system further comprises a rejects crusher for crushing oversize rejects prior to delivering rejects back to the rotary digester.

Abstract: A system, apparatus and/or method for detecting and analyzing light intensities of reflected light from a surface of /a specimen, preferably a web, wherein light is directed onto the surface of the specimen, light reflected from the surface is detected by an array of photosensitive elements, and a signal generated by the array is analyzed to identify reflected light intensities that exceed at least one threshold for a sufficient number of photosensitive elements to warrant classification as indicative of a sufficiently pronounced change in the angularity or reflectance in the surface of the specimen. In particular, the pronounced change can be identified as a defect, for example, a crease, in the specimen surface. Preferably, the array is a CCD array. Preferably, the specimen is a video tape.

Abstract: A film flaw detection system has capacitive sensing members for sensing capacitance changes in correspondence with irregular film variations. The sensing members take two forms. One form senses variation in film thickness by using the film as a dielectric between two plates of the capacitor. Changes in film thickness result in changes in the dielectric and hence in the capacitance. The other form consists of feelers which ride along the surface of the film and which move transversely to the film movement in response to flaws in the film. Each feeler forms a plate of a capacitance, and movement of the feeler changes the distance between this plate and an associated fixed plate which results in a capacitance change. The detecting circuit comprises a phase detection system for measuring phase changes in a high frequency signal. These phase changes correspond to capacitance changes caused by flaws in the film and sensed by either of the two forms of sensing means.
