  • Patent number: 7390144
    Abstract: A method for installing a pre-cast/pre-stressed concrete and steel pile used in the construction of pile foundations and the resulting installed pile that has its distal end anchored to bedrock is disclosed. After the pile is located on bedrock, a first hole is drilled into bedrock that is of sufficient depth to accommodate a lower portion of the steel pipe that extends below the concrete pile and contains a plurality of orifices. A second hole is drilled into bedrock that is below and concentric to the first hole and has a diameter than that is usually less than that of the first hole. The second hole forms an anchoring socket to accommodate an anchoring anchor. Grout is injected into the steel pile and anchoring socket until the grout fills the voids in the interior of the steel pipe. Grout also seeps through the orifices in the lower end of said steel pipe and fills the second hole, and an annular space between the outer circumference of the steel pipe and the walls of the first hole.

  • Patent number: 5673810
    Abstract: A counterweight assembly for a container lid that allows for control over the operating characteristics of the lid during opening and closing. The counterweight assembly is preferably used with a container having one or more walls, a floor, and a lid positioned on top of the walls, the lid being rotatable about a horizontal hinge axis. The counterweight assembly includes a counterweight, and a coupling arm rotatable about a counterweight axis that is located within the container. The counterweight is connected to one end of the coupling arm. The other end of the coupling arm exerts a force against the downward facing surface of the lid.
