  • Patent number: 5248003
    Abstract: A cantilevered jack-up rig having a support for supporting the free ends of the rig's cantilever beams when said beams are extended over a platform to be serviced by the rig, thereby maximizing the lateral reach of the rig and increasing the load capacity at the maximized reach. The support is positioned between the top of the platform and the bottoms of the extended cantilever beams. The top of the support is provided with a motion block to facilitate lateral and rotational motion of the extended cantilever beams relative to the support.

  • Patent number: 4639167
    Abstract: The mobile marine drilling structure is of the submersible type for operation in ice-covered waters. The structure comprises a base for placing the structure on the sea bed, a hull extends from the base, and a deck is supported by the hull. The deck is located above the water line for conducting drilling operations. The hull has an internal frame assembly including ballast tanks, and external wall sections at different inclinations to the horizontal to engage and break up the moving ice masses encroaching on the hull. These external wall sections include a plurality of matching polygonal, frusto-pyramidal, apex-up and apex-down walls extending above the base, and two transitional wall sections to provide two inflection points to the hull.

  • Patent number: 4494785
    Abstract: The round sandwich holder is made of paperboard stock and has folded end sections which form open cup-like receptacles at either end of an elongated accordion-folding central body. The open cup-like ends are the handles to accommodate the insertion of a round sandwich, such as a hamburger. The bottom outside perimeter edge of the sandwich rests along the accordion-folding central body between the open cup-like ends. The accordion-folding central body is then adjusted to accommodate the diminishing bottom edge perimeter of the sandwich as the sandwich is consumed.
