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.

Abstract: Devices, methods, and systems for providing portable dredging flotation hoses capable of being wound on reels in a reduced volume configuration and transported to dredging sites. Some dredge flotation hoses include a first lay-flat hose disposed about a second, inner lay-flat hose and sealed at both ends of the first lay-flat hose to form an inflatable annular space therebetween. Some devices have a coupling member at either end of the lay-flat hoses to receive and couple the inner lay-flat hose within the outer lay-flat hose and provide external access to the channel flowing through the inner lay-flat hose. A closeable orifice can be provided through the body of the coupling device to allow inflation of the annular volume between the inner and outer lay-flat hoses. Lay-flat hose pairs having sizes of 3 and 4 inches to 10 and 12 inches, and other combinations are provided by the present invention.

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.
