| 20130126309 | DEVICE FOR PRODUCING AN ARCHIMEDES SCREW - Disclosed is a device for improving the method of manufacturing Archimedes screws by assembling sectors on a shaft without forming gaps, cutting edges or weak regions between one another and ensuring the continuity of the turns of which the screw consists. It consists of a sector having a turn with a length equal to one screw thread and having a geometry that enables it to be interlocked with another, identical sector. The turn sits on a core, the geometry of which is obtained by following in each case a helical generatrix which is offset through at least one turn thickness. The terminal face of the turn is inclined at an angle with respect to the axis of the sector. The device according to the invention is particularly intended for the production of systems for metering or pumping viscous, pulverulent or granular products, the systems including at least one Archimedes screw. | 05-23-2013 |

| 20140102861 | WORKPIECE FEEDING APPARATUS - In a workpiece feeding apparatus having a rotating shaft adapted to rotate to separate and individually feed a plate-like workpiece suspended side by side in an axial direction along a helical region formed on an outer peripheral surface of the rotating shaft and drop the plate-like workpiece from an edge thereof and a motor rotating the rotating shaft, the rotating shaft includes a first rod connected to the motor, and a second rod rotatably connected to the first rod and having a helical region formed on the outer peripheral surface of the second rod and a workpiece hanger at the edge to extend perpendicular to the axial direction and to be bent at a distal end, such that the second rod stops rotating when the workpiece is hung from the distal end of the workpiece hanger. | 04-17-2014 |
| 20150014127 | Auger with Laser Cladding and/or Laser Heat Treatment and Method - An agricultural auger for conveying grain material is provided. The agricultural auger includes a shaft that is adapted to rotate about a central axis. A flight extends and spirals about the shaft. The flight further includes a base material of a first hardness. A laser treated material is formed on or into the base material along a portion of the flight. The laser treated material comprises a second hardness greater than the first hardness. | 01-15-2015 |
