    Abstract: The present invention relates to a product irradiator having a cartridge loading system. The cartridge comprises a plurality of carriers or totes which are transported as a single mass into an irradiation chamber for radiation processing. Products contained within the totes are irradiated while on the cartridge, but individual totes are transferred around the radioactive source by a tote transfer system. The cartridge product irradiator permits quick changes of cartridges thereby minimizing the time that the radioactive source is not in use, and also permits good radiation dose uniformity in products. The cartridge product irradiator is thus highly efficient and economical to use.

  • Patent number: 5008550
    Abstract: Food products are placed on spaced baskets and conveyed into an enclosure, through a irradiation chamber, and then outwardly from the enclosure. The food products are conveyed through tortuously arranged ductwork which serves to absorb radiation streaming upwardly. A portion of the conveyor is positioned within one or more casings and can be withdrawn, if necessary, to facilitate maintenance and repair.

  • Patent number: 5006041
    Abstract: Intercept arms of a stacker are coupled to the drive chains by connecting links pivotally connected at one end directly to one of the drive chain links so that the pivot point of the connecting link is coincident with the pitch centerline of the drive chain resulting from the fact that the connecting link forms an integral part of the drive chain, directly replacing one of the drive chain rollers. The connecting link design provides a mechanical advantage of five to one and is pivotally mounted and angled so that the connecting link is free to pivot about the chain to avoid interference as the intercept arm moves about the sprocket, providing greater stability to the intercept arm while simultaneously increasing the mechanical advantage thereby significantly reducing power losses.

  • Patent number: 4917796
    Abstract: A lift apparatus adapted for reliable, substantially maintenance-free operation in material transfer systems, including systems that are subject to considerable contamination. The lift apparatus includes an open top container, a support plate for normally supporting the container in upright position, and a ball screw drive for moving the support plate and container between a filling station in which material may be introduced into the container and a discharge station. The container is supported for relative pivotal movement with respect to the support plate, and a chain and sprocket arrangement is provided for automatically pivoting the container to a dumping position as it is raised into the discharge station and for returning the container to its normal upright position as it is lowered from the discharge station following dumping.

  • Patent number: 4890722
    Abstract: A conveyor system comprising a series of buckets supported by a chain along a predetermined endless path having straight portions and at least one internal curve. An individual pivoting arm supports a respective bucket on the chain. Each pivoting arm is pivotally attached to the entrainment means at a first end in fixed orientation to the chain, and pivotally supports the bucket at the opposite, second end. A chain guide engages the chain in advance of an internal curve in the path to cause the second end of the pivoting arm to which the bucket is attached to pivot outwardly and the buckets in turn to follow a diverging curved path of greater radius than the radius of the curve in the path being transited and thereby space the buckets further apart prior to negotiating the internal curve in the path than when the buckets are proceeding along a straight portion of the path.

  • Patent number: 4825998
    Abstract: An apparatus for tipping about a horizontal axis a bucket carried by a conveyor chain around a circuit to fill the bucket with contents at a predetermined location and empty the contents thereof at a predetermined location. The apparatus comprises a bucket pulley mounted for rotation with the bucket on one end thereof concentric with the horizontal axis about which the bucket is tipped, and an elongate bucket pulley-engaging device positioned adjacent said chain at a predetermined point on the circuit where the contents of the bucket are to be emptied. The bucket pulley-engaging device has a length at least as long as the circumference of the bucket pulley and frictionally engagable with the circumference of the bucket pulley to rotate the bucket pulley and thereby rotate and invert the bucket mounted thereon as the chain moves the bucket along the length of the bucket pulley-engaging device.

  • Patent number: 4770287
    Abstract: A bucket conveyor with a pair of parallel draw elements between which the buckets are supported on spindles about which they rotate pendulum fashion. Forward rollers are mounted on the ends of the spindles and rear rollers are mounted at the opposite edge of the bucket. Each bucket has a flange or lip which overlaps the top edge of an adjacent bucket. The rollers on the buckets engage guide rails to properly orient the buckets as they pass over return gears and from the loading area to the dumping area and back again. By maintaining proper orientation of the buckets, the load level of each bucket and thus the capacity of the conveyor is increased. The bucket conveyor is of simple design, has low wear and high conveying capacity.

  • Patent number: 4736832
    Abstract: In a flat link chain bucket conveyor constructed in particular as high-speed conveyor with centrifugal discharging, the buckets (4) are mounted with clearance on the chain (2), in particular on the link pins (3), in such a manner that they are freely movable relatively to the chain under the influence of the forces acting on the buckets within the scope of the existing play. As a result the transmission of shocks and vibrations from the chain to the buckets is very greatly reduced and thus crack formation occurring in the prior art in particular at the bucket securing points is avoided or greatly diminished.
