Abstract: An air flow generating device, a graphene dispersion, and a preparation method thereof are provided. The graphene dispersion is formed by a graphene powder and a processing solvent, wherein the graphene in the graphene dispersion has an average diameter of 0.5 ?m to 1 ?m, 3 to 5 layers, a solid content of 5% to 50%, and a residue oxygen content less than 1 wt %, and after being left to stand for 12 hours, the graphene dispersion has a distribution concentration increasing from the top section to the bottom section of the storage container, a viscosity of 5000 cps to 8000 cps, and a graphene concentration of 20 wt %.

Abstract: A combine harvester with separably driven rotor portions for threshing grain is described herein.

Abstract: An Improved Apparatus and Method for Moving and Placing Granulate is disclosed. The disclosed device is a portable, self-contained apparatus capable of discharging granulate into hard-to-reach areas, as well as providing assistance in covering vast open areas with granulate in a short time. Furthermore, the device and method described herein permit the application of granulate into areas that are normally inaccessible and would require many hours of human labor, and thereby potentially avoiding damage to the site that might be incurred if employing a prior method and device.

Abstract: A particulate material accelerator conveyor includes a housing having a wall with openings therein for an air inlet, a particular material inlet, and a mixture outlet; a feed auger rotatably mounted in the housing and in fluid communication with the particulate material inlet so as to convey particulate material from the inlet into an acceleration chamber within the housing; and a fan rotatably mounted in the housing in fluid communication with the air inlet and the acceleration chamber. The fan includes a plurality of fan blades for accelerating air from the air inlet toward the housing wall and thereby providing a flow of accelerated air along the inside of the wall and toward the particulate material and move therewith toward the mixture outlet. The positioning of the fan in the housing and the resulting air flow therefrom prevents particulate material from contacting the fan blades and thereby damaging the particulate material.

Abstract: An injector for a material transport system includes a helical inducer having a housing with a fluid input port, a material input port and a discharge port, each port is open to an internal chamber of the housing. A rotor with a helical blade is mounted to the housing and constrained for rotation within the chamber. A fluid entering the fluid input port is formed into a fluid vortex having a ventilated core by the rotating rotor blade. A feeder assembly feeds the material to be transported into the material input port where it is carried by the fluid vortex to the discharge port for transmission to a hydraulic transport line.

Abstract: A feed residue saver attachment for combines has a trough adapted to be mounted in a transverse position beneath the rearward portion of a combine to receive residue which the combine would otherwise discharge onto the ground. A driven auger in the trough moves residue out an open end and into an impeller housing from which it is blown through a duct into a wagon. The attachment has alternative modes of operation so that it may be selectively used either to save substantially all the feed residue including chaff, or to save substantially only large material such as corn cobs, corn husks and pieces of stalk (known in some farming areas as "husklage") and permit chaff and other fine material to drop to the ground.
