Abstract: A material processing vibrating screen with diverting systems configured to deliver material, via a plurality of material diverters, to locations closer to a feed end of the screen than would otherwise be done in the absence of the diverters. The diverters can be fixed to a cross member, the underside of a screen, and may be adjustable and easily replaceable. The materials for the deflectors can vary depending upon the material being screened. The screen may be also be a variable sloped vibrating screen.

Abstract: The ends of cigarettes (10) are verified in a cigarette magazine (12) by testing units (24, 25) coordinated with the ends of cigarettes (10) at a testing level (20). The testing units (24, 25) consist of mutually adjacent and removable testing elements (33) with transmitters (28, 29) and planar receivers (30, 31) at the sides of the cigarettes. The testing units (24, 25) are fitted so that they can move parallel to the axis of the cigarettes (10) relative to the cigarette magazine (12), so that the testing unit (25) can moved back in order to advance the cigarettes from the cigarette magazine (12).

Abstract: A granular material cleaning apparatus and method. The apparatus has an upright container housing assembly; an inlet housing assembly pivotally connected to the upright container housing assembly to receive a contaminated granular material; and material inlet control assembly mounted to the upright container housing at an upper inlet portion thereof. A discharge housing assembly is mounted to the upright container housing assembly; and a material flow channel assembly is mounted within the container housing assembly generally underneath the material inlet control assembly to initially receive the contaminated granular material at an upper end thereof and pass the same under gravity moving transversely on the material flow channel assembly until discharged into the discharge housing assembly.

Abstract: A multiple deck screening machine wherein the feed material is divided into separate equal fractions on a rubble screen deck and scalp screen decks. Each deck includes downwardly slanting distribution panels having serrated lower edges. Particulate flow over the serrated edges is divided into separate fractions. Each adjacent fraction passes into a different parallel vertical channel which serves a particular screen deck via a chute. The chutes and channels extend the full width of the screens. Flow across the serrated edges is separated due to the notches and tongues and upstanding dividers along the common edge to each notch and tongues. Each notch and tooth of the rubble screen deck is disposed in juxtaposition to an opposed tongues and notch respectively so that excess flow over a tongues may pass over its channel into the channel of the opposed notch. The rubble screen deck including a pair of downwardly and inwardly inclined distribution panels which oppose each other and define a flow gap therebetween.

Abstract: An apparatus for cleaning grain and the like by gravity feeding through a casing having within it a central zig-zag chute with top-hinged screens resting across openings in each underside of each zig and each zag of the chute, the action of the grain itself resonating the screens for increased agitation. A large access door to the edge of the screens permits each inspection and replacement as the screens are hinged by means of a top strip which slides into an open-ended slot at the knee of each zig and each zag.

Abstract: A grain cleaner having a plurality of cleaning sections radiating outwardly from a grain inlet. Each cleaning section has upper and lower downwardly sloped screens over which grain flows by gravity to sift out fine foreign material. Upper and lower foreign material chambers underlie respective screens, and external bypass ducts bypass foreign material from each upper chamber to an associated lower chamber of each cleaning section. Each lower foreign material receiving chamber communicates with a centrally located foreign material discharge outlet at the bottom of the cleaner.

Abstract: For screening oversized objects and especially long slender particles wherein the long dimension of the particle is aligned in the direction of flow through a fluid-flow conduit, there is provided a screen comprising a pair of opposing corrugated surfaces, the folds or corrugations on the opposing surfaces being substantially parallel, and separated by a distance, and having a wave length, determined by the size particle to be screened. Preferably, the corrugated surfaces are formed as two sets of a plurality of corrugated plates inserted within and extending along the direction of fluid-flow in a conduit, the sets being relatively movable between a position where the two sets are interleaved, and a position where the two are separated.

Abstract: An apparatus for sizing or separating different types of particulate material such as grain, seeds and the like without the need for replacing the sizing screens includes a movable diverter disposed between upper and lower sets of screens. When the diverter is in a first position, material passing through a first sizing screen is directed to the top of a second sizing screen and material which has not passed through the first sizing screen is directed to a discharge pan. When the diverter is in a second position, material which has passed through the first sizing screen is directed toward a discharge pan and material which has not passsed through the first sizing screen is directed toward a second sizing screen.
