Abstract: Apparatus and method for automatically adjusting a rate at which a document decelerates when entering a sort pocket of a document processing machine. The apparatus includes a track adapted for transporting the document, a guide wall, and a stacker flag spaced away from the guide wall to define the sort pocket therebetween. The sort pocket communicates with the track so that the document exits the track to enter the sort pocket. A wave spring is disposed proximate the guide wall so that the document engages the wave spring and is decelerated by the wave spring when the document enters the sort pocket. The weight of the document is calculated, and a signal is produced that represents the weight of the document. The wave spring is distorted according to this signal to vary a configuration of the wave spring depending on the weight of the document to decelerate the document at an optimal rate.

Abstract: Tablets, pills or like discrete products are fed into the upper section of an upright conduit to descend into a vessel under the action of gravity. Excessive acceleration of descending products is opposed by an air stream which is induced by a pump and flows in the conduit counter to the direction of advancement of the products. The vessel contains one or more partitions which have outwardly and downwardly sloping upper sides and central openings for the conduit. The outlet of the conduit discharges products first onto the bottom wall of the vessel and thereupon at a level above the lowermost partition which latter causes the products to slide outwardly toward the sidewall of the vessel. When the space between the bottom wall and the lowermost partition is filled, the lowermost partition prevents crushing of products below it under the weight of products which gather above the lowermost partition.

And the free tip ends of the trapezoidal plates define an opening of a diameter smaller than that of articles to be dropped. When the dropping articles drop, they enlarge the opening of each of the shock absorbing members.

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.

Abstract: A dust suppressor for reducing or substantially eliminating dust in the loading of a particulate commodity, operating on a "dead box" principle but without the use of power operated valves. The dust suppressor normally operates on a three-stage principle, the first stage utilizing an adjustable damper valve which slows the velocity of flow, the second stage comprising a fixed deflector which directs and initially smooths the flow, and the third stage comprising a counterweighted, automatically operating butterfly valve which finally shapes and smooths the flow. Maximum dust suppression is obtained because dust cannot escape the dust suppressor without being forced back into the grain flow, because the velocity of the grain flow is reduced and because the grain flow discharged from the dust suppressor is smooth, non-turbulent and shaped.

Abstract: A material distribution device is disclosed for spreading material such as grain during bin loading. A hopper, having a plurality of funnels therein acts in conjunction with the grain to automatically establish the path of the grain through the hopper according to flow rate of the grain passing through the hopper.

Also, the location of the pivot of the tension link is such that a force component is developed which assists the retracting force acting on the stop member.

Abstract: The grain loading apparatus 2 comprises the housing 4 which is attached to the end of the grain discharge chute. The housing 4 includes a shutoff valve 12 located proximately to a material outlet opening 9.
