Abstract: Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.

Abstract: The invention relates to a portable drive-over grain hopper for use in moving grain. The hopper has an endless chain linkage with laterally extending paddle assemblies spaced therealong. A grain transfer bed extends from a low profile location in position to receive grain from a belly-dump or side-dump truck or trailer to a higher elevation discharge outlet. The grain transfer bed has a generally planar lateral width which is the same from the grain inlet to the discharge outlet, and is substantially spanned by each paddle assembly. Fold-down ramps are provided adjacent the inlet to allow a truck or trailer to drive over the grain hopper, which has a very low profile. The grain hopper has removable wheels and a removable hitch to allow it to be relocated as desired.

Abstract: An improved auger assembly for providing a sealed path for transport of grain. The improved auger assembly includes a first angularly adjustable hopper tube, a second hopper tube, and a joint mechanism. The first angularly adjustable hopper tube contains a first auger for transporting grain from a first grain-containing volume. The second hopper tube contains a second auger for transporting grain to a second grain-containing volume. The joint mechanism couples the first and second hopper tubes and allows the grain transported by the first auger from the first grain-containing volume to be further transported by the second auger to the second grain-containing volume. The joint mechanism includes flexible flaps that sealably couple the first hopper tube and the second hopper tube at all angular orientations of the first hopper tube relative to the second tube.

Abstract: A center drive portable auger system for transporting particulate material. The auger includes an auger tube having a feed end and a discharge end, an auger drive shaft within the auger tube, and an auger flighting mounted to the auger drive shaft for transporting particulate material from the feed end to the discharge end of the auger tube. A gear box is positioned adjacent an external surface of the auger tube between the discharge end and the feed end for center driving the auger flighting. Since the central gear is external to the auger tube it does not restrict the flow of the particulate material within the auger tube, does not leak oil into the particulate material, and runs cooler than the internal gear boxes due to less friction during operation. A drive linkage operates between the gear box and the auger drive shaft for driving the auger flighting.

Abstract: A feed auger for transporting particulate material to a main auger which has a drive shaft driven by a direct mechanical connection from a PTO of a tractor vehicle. The feed auger is attached to a hopper at one end and pivotally mounted to the main auger at the other end such that particulate material entering the hopper is transported through the feed auger and into and through the main auger. The feed auger is driven by a hydraulic system operated from the drive shaft of the main auger, the hydraulic system providing independent control of the operation of the feed auger.
