Abstract: A linear-motor stator assembly comprising a stator and an integral line reactor in one housing. The reactor has inductor coils which are connected in series with the stator windings to compensate for unequal inductances in the stator phases and balance the polyphase currents into the stator.

Abstract: A trough-belt conveyor with adjustable bearing support wings and methods for operating the conveyor to sort or destack articles. The conveyor includes a flexible conveyor belt supported in a series of support beds. Adjustable support beds have a base bearing member flanked by a pair of bearing wings. One or both of the wings are adjustable to raise or lower the sides of the belt above and below the plane of the center of the belt supported atop the base member.

Abstract: A shrimp deveining machine with adjustable blades. The deveiner has an inclined trough with groups of blades arranged in a zig-zag pattern. The trough is lubricated by water to help shrimps advance along the blades, which slit the shrimps' backs to expose their veins. Blade-height adjusters adjust the height of the blades above the trough. Blade-angle adjusters adjust the angles of the blades relative to the length direction of the trough. Magnets are used to hold the blades in place for easy replacement. A feed tank at the entrance to the trough includes a serpentine path to separate the shrimps.

Abstract: A conveyor system and method for cascaded accumulation on a series of in-line roller belts. An accumulation system comprises a series of roller belts that can be actuated in contiguous zones to accelerate conveyed articles forward at twice the belt speed. When articles start to accumulate on the accumulation conveyor, the belt rollers are deactuated downstream to upstream zone by zone. Then the belts are stopped as they fill with accumulated articles. The process is repeated in cascade for the upstream roller belts as articles continue to accumulate.

Abstract: A conveyor for transferring articles off the end of a conveyor belt onto a discharge conveyor. The conveyor comprises a conveyor belt overlain by belt strands along a carryway. The belt strands are received in recesses below the conveying surface of the conveyor belt. The conveyor belt travels an inner circuit inside an outer circuit encircled by the belt strands. The outer circuit diverges from the inner circuit at an end of the carryway. The belt strands extend the carryway and strip articles from the conveyor belt to transfer them to a downstream discharge conveyor or receive articles from an upstream infeed conveyor.

Abstract: A conveyor belt and a weighing system for weighing articles conveyed on a conveyor belt. The conveyor belt includes an array of force-sensing elements embedded in the belt to measure forces normal to the belt's conveying surface. The force-sensing elements form parts of passive resonant circuits that each include a capacitor and an inductive coil.Either the capacitor or the inductive coil can be a force-sensitive element. Measuring circuits external to the belt include an oscillator having a coil that inductively couples to the resonant circuit in the belt as it passes closely by. A force applied to the belt at a force-sensitive element changes the resonant frequency of its resonant circuit, which also causes a change in the oscillator frequency. Frequency detectors in the measuring circuits measure that frequency change and convert it into a proportional force value used to compute the weights of conveyed articles on the fly.

Abstract: A self-biasing conveyor belt scraper for a conveyor belt trained around a sprocket includes a base mounted on a shaft below the sprocket and a tapering scraper tip extending from the base. The top of the base contacts the conveyor belt at a first location. The conveyor belt pushes against the top of the base to bias the tapering scraper tip into contact with the conveyor belt at a second location.

Abstract: A spiral conveyor and a method for taking up slack in a modular conveyor belt traveling a helical path. The spiral conveyor includes a rotating cylindrical drive drum with parallel drive members extending from the bottom to the top of the drum on its periphery. Each drive member includes an outwardly protruding ridge extending from the bottom to the top of the drum for engaging the inside edges of the belt. A motor-driven take-up shaft and shaft-mounted sprocket set takes up slack in the belt after its release from the drum. To control tension at the discharge of the belt from the drive drum, the take-up motor is normally operated in a closed-loop control mode, but switches to an open-loop constant-speed control mode when the take-up motor stalls.

Abstract: A multi-directional roller assembly for directing articles in a conveying system. The multi-directional roller assembly has a rotatable roller frame housing at least one set of mutually-actuating rollers. The multi-directional roller assembly directs an article supported by the assembly along a trajectory determined by the orientation of the multi-directional roller assembly relative to an input force. The orientation of the multi-directional roller assembly may be changed to change the trajectory. A conveyor system may include an array of multi-directional roller assemblies. An actuator controls the orientation of the multi-directional roller assemblies individually and may also control an array of multi-directional roller assemblies as a group.
