S. Elwood Yandle, II has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11946545
    Abstract: The present invention provides a method of replacing a failed pump seal of a pump having a pump housing and a rotating pump shaft. As part of the method, there is provided a specially configured rescue seal. The rescue seal is placed on the pump shaft above the failed seal so that the pump shaft extends through both the failed seal and the rescue seal. In order to affix the rescue seal to the pump shaft and above the failed seal, a plurality of studs are first attached to the pump housing after removing some of the bolts that fasten the failed seal to the pump housing. The failed seal is then secured to the studs with nuts. Nuts are then placed on the studs to secure the rescue seal to the studs above the failed seal.

  • Patent number: 11644132
    Abstract: Apparatus and method for shielding leakage from a flanged pipe coupling comprising: a housing having a front wall, a rear wall, and a top wall, the top wall depending downwardly to form side walls intermediate the front and rear walls thus forming a closure having a bottom which is open; wherein the housing contains an interior space in between the front and rear wall and below the top wall, the interior space shaped to fit around a flanged pipe coupling; and wherein the housing is shaped so as to prevent rotation of the apparatus with respect to the flanged pipe coupling.

  • Patent number: 11085458
    Abstract: An improved pump and sealing assembly having particular utility to vertically extending pumps/pump shafts provides an arrangement that enables field repair as opposed to requiring travel of the host vessel to a shipyard. The apparatus includes an adapter housing that is configured to provide easy access to set screws that enable field disassembly. This adapter housing carries a sleeve and a bearing. The adapter housing can be fitted to a pump seal assembly that can include a mechanical seal and under bearing assembly.

  • Patent number: 10480657
    Abstract: An improved mechanical seal and repair method can be used with mechanical pump seal assemblies. The improved seal utilizes rotating and non-rotating sections of improved configuration, each of which can form a seal using a standard size carbon-face O-ring. The rotating section includes an upper seal member and a lower drive member, the upper seal member being made of a first material and the lower drive member being made of a second material, the upper seal member and the lower drive member being connected such that movement of the lower drive member causes movement (rotation) of the upper seal member. The mechanical seal can be in the form of replacement parts that replace the old parts without modifications to the overall seal and assembly.

  • Publication number: 20140345732
    Abstract: A modular hydraulic hammer reduction system for railroad tank cars includes tubular hydraulic hammer reduction devices which include means to connect the tubular devices to flanges other than by welding or being cast together. For example, the tubular devices can be press fit into the flanges, or the tubular devices can be connected to the flanges with snap rings (preferably spiral-lock snap rings), or even more preferably the tubular devices can be press fit into the flanges and the tubular devices can be connected to the flanges with snap rings (preferably spiral-lock snap rings). The advantage of this modular construction is that one can manufacture multiple tubular devices and multiple flanges of each type, and connect the flanges to the tubular devices on an as-needed basis.

  • Patent number: 6715270
    Abstract: Apparatus similar to a Weed-Eater® weed trimmer, but instead of monofilament line, it uses recycled coat hangers to cut weeds. There are two plates, the lower one having grooves within which to fit the coat-hangers after they are prepared using a special tool to bend them to the proper shape. Aside from the cutting part, the rest of the machine can be like a Weed-Eater® brand weed trimmer. The two plates are held together with a retaining nut. Hardwire, wire cable, nails, or heavy duty plastic cord can also be used as blades.

  • Patent number: 6382233
    Abstract: A mobile tank car or like vehicle includes a mechanical hydraulic dampening device having kinetic energy dissipating baffles in its interior with no moving parts. The moving tank car carrying a liquid load, such as for example a railroad tank car, including a rupture disc assembly or a safety relief valve at the top of the tank to prevent fracturing of the tank due to excessive pressure. The dampening device is located in line between the rupture disk assembly or safety valve and the liquid load. When the tank is suddenly moved, the shifting liquid load passes through the pipe-like device, impacting against impact surfaces of a baffle, causing its energy and the hydraulic hammer action to be dissipated.
