  • Patent number: 7509977
    Abstract: Devices and methods for evenly distributing sludge, including manure and industrial sludge, to numerous hoses, over a large range of sludge supply pressures. Some devices include a housing having an inlet for receiving sludge under pressure and several outlets disposed outwardly through the housing cylindrical wall for coupling to hoses. The devices can include a rotating plate within the housing sweeping one or more baffles over the outlets to momentarily occlude the outlets and reduce flow through the occluded outlets. The baffles can include a first portion secured to the plate and a second portion removably secured to the first portion and/or the plate. Changing the total length of the baffles can change the affective cross-sectional area of the outlets available for flow at any instant in time.

  • Patent number: 6799591
    Abstract: A wash fluid containment system includes an elevated, fluid impervious surface upon which items to be washed are placed for washing. The surface is configured to cause wash fluid to flow to an edge of the surface and off of the surface to prevent buildup of wash fluid on the surface. A collecting trough is positioned in fluid flow communication with the edges of the surface to which the fluid flows to catch and collect the fluid as it flows from the surface. Used wash fluid is taken from the collecting trough for disposal or recycling and solids and debris can be easily removed from the trough.

  • Patent number: 6427612
    Abstract: A liquid manure application system, including a drag hose assembly and three point hitch adapted to retain the assembly in the course of operation while permitting the releasable three point attachment of tillage tools. The hitch itself provides dimensions and characteristics adapted for such use, including a structural attachment site for the drag hose assembly and a side load capacity considerably greater that comparative available hitches, and sufficient to withstand the side load forces encountered in the course of manure application.
