  • Patent number: 5924490
    Abstract: A well treatment tool is installed along the sucker rod string of a well, within the surrounding production tube string. The tool provides for the distribution of a treatment fluid (solvent, etc.) within the fluid being pumped or flowing from the well. The tool receives treatment fluid through the hollow sucker rod string, and distributes the fluid through a valve which is set at a predetermined pressure. When the treatment fluid pumped down the sucker rod string from the surface exceeds the predetermined opening pressure of the valve, the treatment fluid is distributed into the production tube string through one or more passages in the tool. The present tool may be used simultaneously with well production, with fluid (oil, etc.) rising up the production tube string, carrying the treatment fluid therewith. The treatment fluid is thus distributed throughout the local fluid processing system, including pipelines from the well, any initial treatment operations, and any storage tanks.

  • Patent number: 5921709
    Abstract: A ditch check for controlling erosion or sediment run-off in a ditch or swale is configured as a generally planar panel. The panel has suitable water-conducting passages to permit and is given holes to insert anchor stakes to anchor the panel to the ground. The panel is preferably made substantially of a polymer or resinous moldable material. The panel is given such formed side edges that adjacent panels can overlap or enmesh one another where they meet to close a gap therebetween. It is optional that the panel be stackable with other like panels, for greater convenience during non-use periods, as while being transported and/or during storage. Given the foregoing, the panel is meant to replace straw bales as ditch checks because the panel is very much lighter, is non-absorbent and inexpensive, and is indefinitely reusable.

  • Patent number: 5915880
    Abstract: A cylindrical structure suitable for use as a drainage culvert made from the side walls of discarded motor vehicle tire casings. The side wall sections are stacked and bonded in axial alignment so that the concave face of each of the next adjacent side wall faces the convex face of the next adjacent side wall. One end face of the structure is thus concave and the other end face is convex so that the cylindrical structure can be placed in close alignment with the concave end face of one cylinder in close abutting contact with the convex end face of a second cylinder. Wide kerfs are cut in selected side walls between the outer rim of the side wall and the inner rim so that the selected side walls can expand or contract during banding to provide a rather uniform opening in the cylinder. The kerf also allow the cylinders to weep when water is being conducted therethrough.
