20140360014 | METHOD FOR PRODUCING A BUILT HOLLOW VALVE OF AN INTERNAL COMBUSTION ENGINE - A method for producing a hollow valve of an internal combustion engine may include providing a valve stem and a valve disc having a valve bottom and a valve cone; placing the valve bottom centrally in a mounting of an assembly device; holding the valve stem via a holding device; concentrically placing the valve stem onto the valve bottom and rotating the valve stem together with the valve bottom; welding the valve stem to the valve bottom; pushing the valve cone over the valve stem until the valve stem contacts the valve bottom; welding the valve cone together with the valve bottom; and welding the valve cone together with the valve stem. | 12-11-2014 |
20140360447 | GAS EXCHANGE VALVE OF AN INTERNAL COMBUSTION ENGINE - A gas exchange valve of an internal combustion engine may include a hollow valve stem and a valve disc. The valve disc may include a valve bottom and a hollow valve cone which is connected to an outer edge of said valve bottom. The hollow valve cone may taper with increasing distance from the valve bottom. The valve stem may pass through the hollow valve cone. The valve stem may be fixedly connected on the one hand to the valve bottom and on the other hand to the tapered end of the valve cone. The valve stem may include a first hollow space which is fluidically separated from a second hollow space arranged in the valve disc. The first hollow space and the second hollow space may have a different cooling agent filling level. | 12-11-2014 |
20140360452 | METHOD FOR PRODUCING A BUILT HOLLOW VALVE - A method for producing a hollow valve of an internal combustion engine may include providing a hollow valve stem, a valve cone, and a valve bottom; pushing the valve cone over the valve stem via a press fit, wherein the valve cone includes an outer surface transitioning to the valve stem to define a testing surface; and welding the valve cone to the valve stem via at least one of a laser beam and an electron beam, wherein the welding occurs such that no melting of the outer surface in the region of the testing surface of the valve cone occurs. | 12-11-2014 |

20080302888 | Fluid delivery system - An impeller system is provided for the delivery of a fluid, such as liquid manure, through a manifold system to a plurality of hoses. The impeller includes multiple blades for driving the fluid toward the manifold outlets. The impeller also includes a plurality of shut-off gates to close off multiple outlets and, therefore, increase the pressure to the remaining outlets. As the impeller rotates, openings to various outlets are opened and closed, thereby increasing the pressure of the fluid delivered to each of the outlets. | 12-11-2008 |
20080302902 | Hose reel system - A hose reel system for winding a liquid manure hose. The hose reel includes a spool pivoted in alignment with the wheels and axles of the system to allow for even winding of the hose on a spool. The spool is provided with curved domes on either, end and a protective bar to prevent the hose from winding beyond the ends of the spool. Pivoting the spool in alignment with the axle allows for a more even winding and unwinding of the hose, thereby reducing torsion, kinks and other damage to the hose during the rolling and unrolling processes. | 12-11-2008 |
20080302903 | Hose reel system - A hose reel system for winding a liquid manure hose. The hose reel includes a spool pivoted in alignment with the wheels and axles of the system to allow for even winding of the hose on a spool. The spool is provided with curved domes on either, end and a protective bar to prevent the hose from winding beyond the ends of the spool. Pivoting the spool in alignment with the axle allows for a more even winding and unwinding of the hose, thereby reducing torsion, kinks and other damage to the hose during the rolling and unrolling processes. | 12-11-2008 |
20080303268 | Fluid transport system - A fluid delivery system for a fluid distribution system such as a manure distribution inlet. The invention provides an improved coupling between a supply hose and the newer distribution implement includes an angled pipe coupled to a first collar and a second collar. The collars define keyways within which rotate an annular key provided around an inlet pipe and an annular key provided around an outlet pipe. The inlet pipe, outlet pipe and angled pipe are preferably constructed of polished steel to reduce the wear associated with constant rotation of the pipes relative to one another. The combination of the keyways and polished steel construction allows the pipe to be rotated constantly with only a minimum amount of wear, and improved maintenance and failure characteristics. | 12-11-2008 |
20130145980 | FOLDING FLOATING VESSEL - A foldable floating vessel providing a large surface area and heavy payload capability when deployed into a liquid, such as a manure lagoon. The vessel may be folded for transport using linear actuators to fold two hulls of the vessel from a first position substantially horizontal to a second position substantially vertical. Driving and steering assemblies are provided on a center frame to which the foldable hulls are pivotably connected. | 06-13-2013 |
20140077020 | HOSE REEL SYSTEM - A hose reel system for winding a liquid manure hose. The hose reel includes a spool pivoted in alignment with the wheels and axles of the system to allow for even winding of the hose on a spool. The spool is provided with curved domes on either, end and a protective bar to prevent the hose from winding beyond the ends of the spool. Pivoting the spool in alignment with the axle allows for a more even winding and unwinding of the hose, thereby reducing torsion, kinks and other damage to the hose during the rolling and unrolling processes. | 03-20-2014 |
20140112093 | FLOATING MANURE AGITATOR - A floating manure agitator that floats on the surface of a manure lagoon and that may be remotely controlled to agitate manure supernatant into a slurry with sludge settling on the bottom of the lagoon. The agitator is provided with a plurality of fluid outputs, the direction of which may be controlled to motivate and steer the agitator. The outputs are angled to develop vortices of supernatant into the sludge to further mix the materials into a slurry. | 04-24-2014 |
