Abstract: The particulate material handling system comprises a tube, an endless belt that passes through the tube and returns outside of the tube, and a flighting that is suspended a predetermined distance from the belt through the entire length of the tube. The distance may be varied for the various materials being handled. An intake hopper is mounted at one end of the tube for receiving the material to be moved and a discharge spout is mounted at the other end of the tube for discharging the material from the tube. The endless belt and flighting are driven such that their speed may be varied and such that their relative speeds are synchronized to drive the material at substantially the same speed whether it is being carried by the belt or the flighting. The combination of the belt and the flighting drives the material through the tube, minimizing damage to the material, which may be granular fertilizer, pulse crops, grains or other particulate material.

Abstract: A mounting system for a compressible conveyor belt drive roller comprises lower and upper bearing assemblies, and in accordance with a first embodiment, a jack screw mechanism is provided for engaging the upper bearing assembly so as to cause axial movement of the upper bearing assembly toward and away from the lower bearing assembly. As a result of such axial movement, the compressible conveyor belt drive roller is axially compressed or expanded so as to accordingly cause radial expansion and contraction of the drive roller. The radial expansion and contraction of the drive roller alters the circumferential extent of the drive roller which alters the conveying speed of a conveyor belt operatively engaged with the outer peripheral surface of the drive roller such that the conveyance speed of the conveyor belt can be synchronized with the conveyance speed of an oppositely disposed paired or companioned conveyor belt.

Abstract: A device for conveying separated objects (1), especially disk-shaped objects, such as coins, includes a guideway (2) and with a lamellar belt (4) circulating on a conveying arm (3), wherein a strand (5) of the lamellar belt (4) facing the guideway (2) is guided over the entire longitudinal extension of the conveying arm (3), providing that lamella tips (6) of the lamellar belt (4) pointing toward the guideway (2) have a distance A from the guideway (2) that is smaller than the smallest height of an object (1) over the guideway (2). A support feature (8) for supporting the lamella tips (6) in the direction at right angles to the direction of conveying is installed at least in an intake area (7) of the conveying arm (3).

Abstract: A dual belt conveyor includes a pair of flexible endless loop conveyor belts arranged at an incline with a lower flight of the upper belt in face-to-face conveying relationship with an upper flight of the lower belt to retain and convey granular material between the belts. Drive pulleys are connected to both belts to move the belts at the same speed, and the conveying flights of the belts are journaled through a trough which forces the belts into a curved concave orientation between the side edges with the upper belt biased downwardly into engagement with product on the lower belt to retain product therebetween.

At least one corner of the back edge or of the front edge of the book block is aligned with a position, which can be set in a predefined manner, by relative displacement of the two sides of the book block in the plane of the book block. The book block is then clamped in a force-locking manner by the transport device.

Abstract: An assembly for conveying stacked documents includes a conveying surface extending along the conveying path and a conveyor roller that is suspended opposite to the conveying surface for movement between positions at different distances from the conveying surface. In the operating condition, the conveyor roller exerts a press-on force. The assembly also includes a transmission for driving the conveyor roller. The transmission is coupled with the conveyor roller in such a manner that if a couple is exerted on the conveyor roller in the conveying sense, a force directed against this press-on force is exerted on the conveyor roller. As a result, the temporary increase of the couple and the temporary reduction of the circumferential speed of the conveyor roller is limited.

Abstract: An object stabilizing device for use with a continuous moving surface is disclosed and which includes a drive roller disposed in spaced relation relative to a continuous moving surface; and a flexible continuous belt having a proximal end driven by the drive roller and an unentrained distal end which is disposed in rested relation on the continuous moving surface.

Abstract: A stabilizer unit for material on a moving conveyer surface comprises a framework mounted over the surface with a drive pulley making driving engagement therewith. A drum is rotatably supported in the framework and carries a stabilizer surface thereon. The drive pulley is coupled to the drum to rotate the drum with its peripheral velocity substantially equal to that of the drive pulley, thus imparting the corresponding velocity to the stabilizer surface. The stabilizer surface can be a belt loosely carried on the drum, which follows a path with a first section overlaying the conveyer surface, a second section in engagement with a segment of the drum surface, and third and fourth sections extending between the drum surface and the respective points of separation of the stabilizer belt from the conveyer surface. Movement of the conveyer surface rotates the drive pulley and thereby the drum to advance the stabilizer belt around its path at a speed equal to the speed of the conveyer surface.

Abstract: A screw conveyor for conveying containers such as bottles and cans is arranged adjacent a guide rail which restrains the containers to stay in the groove of the screw until they are discharged, this being known per se. The angles for the screw conveyor and guide rail are adjustable to assure guidance of the center points of containers of any size along the same straight line without relying on inserting test containers. The guide rail is supporting on a transversely movable carriage and is pivotable thereon. The undriven end of the screw is supported on a member which is movable by a small amount. Stop elements such as bolts having different lengths are mounted in groups on a slidable member to enable positioning concurrently a stop element for the screw conveyor and a stop element for the guide rail pertaining to a particular container size and the stop elements react against stops on the carriage and the screw conveyor support member.

Abstract: A fuser belt for a reproduction machine is disclosed. The belt may have one of several configurations which all include ridges and interstices on the outer surface which contacts the print media. These interstices are formed between regularly spaced ridges, between randomly spaced particles, between knit threads. These interstices allow the free escape of steam from the media during high-temperature fusing of the reproduction process. As the steam escapes freely, the steam does not accumulate in the media causing media deformations and copy quality deterioration. Additionally, media handling is improved because the ridges and interstices reduce the unwanted but unavoidable introduction of thermal energy into the copy media.

Abstract: A first-in last-out reservoir system for storage of stacked cigarettes or filter rod sections has two coaxial helically convoluted walls which are rotatable about their common axis on grooved internal and external rolls and define a helical chamber with an opening for admission of successive increments of a stack of rod-shaped articles. The walls are elastically deformable and those portions of the walls which are adjacent to the opening are spaced apart at a distance exceeding the length of an article to permit unimpeded admission of articles into or evacuation of articles from the chamber. The articles are delivered to or removed from the opening by one reach of an endless belt conveyor which is tangential to the walls. The pitch of the walls is constant or nearly constant, and the walls are rotated by one or more shafts for the aforementioned grooved rolls.

Abstract: Logs are advanced substantially in the direction of their longitudinal axes through a saw while engaged between a driven pusher dog and a retarded holdback dog. The pusher dog is on an endless carrier chain located above an initial log support, and the holdback dog is on an endless carrier chain located below the log path and forwardly of the support. Logs on the support are movable angularly and laterally from the machine axis to displaced positions which are unobstructed by the carrier chains, to permit offset sawing and taper sawing. Chipper heads produce planar surfaces on logs approaching the saw. A retractible preliminary holdback dog engages the forward end of a log and moves past a bottom-flattening chipper head to a tranfer area where the chain-carried holdback dog engages the log and the preliminary holdback dog is retracted.
