  • Patent number: 4807734
    Abstract: Apparatus for loading friable nuclear fuel pellets into a sintering boat from a pellet press which ejects newly made pellets. An inclined pellet chute (preferably a tube) receives the ejected pellets and discharges them against a first resilient brush which reflects the pellets downwardly to a second resilient brush. The brush tips are spaced apart such that a pellet moving downward along the second brush contacts the flexible brush tip of the first brush before dropping off the second brush (preferably with near-zero velocity) into the sintering boat.

  • Patent number: 4765453
    Abstract: A system for loading friable nuclear fuel pellets into sintering boats from a pellet press which ejects newly made pellets. A chute receives the ejected pellets and discharges them into an upright bowl at a location towards the top of the bowl near its inner surface with a tangential horizontal component of velocity. The bowl, which has an open smaller diameter bottom, is rotated such that the bowl near the pellet-discharge location has a velocity which generally matches the magnitude and direction of the horizontal component of the velocity of the pellets at the discharge location. A conveyor moves a line of adjacently positioned boats horizontally beneath the bottom of the bowl. A flexible strap which cushions the pellets as they enter a sintering boat also acts as a seal between boats.

  • Patent number: 4738774
    Abstract: An apparatus for loading open top grain hopper rail cars and trucks which eliminates the buildup of a core of small material and grains directly beneath the load out spout. Also, the grain will not build up heat as easily with the core eliminated and a more representative sample, for grading purposes, can be obtained from the hopper car or truck. The spout line buster is a small, stove-shaped chamber which attaches to the end of a grain load out spout and is lowered about six inches into the hopper rail car or truck being loaded. The grain passes through the down spout and enters the spout line buster where the flow of the grain is directed and slowed by a series of baffles or flow guides. In the model designed for loading hopper rail cars, the grain strikes a screen assembly consisting of a cone screen and two diagonal screens.
