Patents by Inventor Shelby M. Shreve

Shelby M. Shreve 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: 11878485
    Abstract: Embodiments of the present invention include a press base assembly, a strengthening ring for use with press bases and related methods. In one embodiment, a press base assembly includes a press base having a body that includes a piston cavity at one end. The body, at a second end opposite that of the piston cavity, may exhibit a desired geometry. A strengthening ring may be shaped, sized and configured to substantially mate with the geometry of the second end of the body and be placed thereover. For example, the geometry of the second end may be substantially circular exhibiting a particular diameter and circumference. The strengthening ring may have substantially circular internal surface sized and configured such that the strengthening ring is positioned on the second end of the body in a manner that results in an interference fit between the two components.

  • Patent number: 11858230
    Abstract: In an example, a cubic press is described having press bases with spacers disposed between adjacent press bases. Sets of two or more tie bars are also disposed between adjacent press bases. The tie bars are placed in a state of compression while the spacers are placed in a state of compression. During operation, the press bases may become displaced relative to one another such that additional tension is experienced by the tie bars while the amount of compression experienced by the spacer is reduced. The tie bars exhibit a relatively small cross-sectional area as compared to the cross-sectional area of the spacer.

  • Patent number: 11524473
    Abstract: High pressure presses, components for high pressure presses and related methods are provided herein. In one embodiment of the invention, a press base may include a piston cavity formed in the press base and a piston cavity sleeve positioned in the piston cavity. The piston cavity sleeve may include a wall having an outer surface and an inner surface opposite the outer surface. The piston cavity sleeve may further include a floor having an upper surface and a lower surface opposite the upper surface. An outer radius may be formed at a juncture of the outer surface of the wall and lower surface of the floor and an inner radius may be formed at a juncture of the inner surface of the wall and upper surface of the floor. The inner radius may exhibit a radius of curvature that is greater than a radius of curvature of the outer radius.

  • Patent number: 10195700
    Abstract: A high pressure press assembly along with related methods and components for the press assembly are provided. In one embodiment, a press assembly includes a first press base having one or more tie bar receiving holes extending therethrough. A second press base may also include one or more tie bar receiving holes extending therethrough. A tie bar extends between the first press base and the second press base. A tensioning assembly is operatively coupled to the tie bar to place the tie bar in tension.
