  • Patent number: 9573795
    Abstract: A drill pipe screen transporter device rotatably couples a drill pipe screen to a transporter for its insertion and/or extraction into and out of a derrick assembly. A first plate assembly has a first base plate; and first and second spacer plates have arcuate notches for engaging the transporter. U-shaped bolts secure the first plate assembly to the transporter. A second plate assembly rotatably connected to the first plate assembly, has an aperture for supporting the screen. A collar assembly, spacer collar and pivot pin rotatably attach the second base plate to the first base plate for rotation of the screen relative to the transporter. A swivel stopper engages the first base plate of the first plate assembly when the second plate assembly is rotated a predetermined amount. A counterweight located opposite to the swivel stopper returns the second plate assembly to its initial horizontal positioning.

  • Patent number: 4489815
    Abstract: This invention relates to dual purpose tote bags in which one purpose is to provide a carrying bag or box and the other is to provide for a semi-rigid surface, which can be used for carrying and, holding food and for providing a table-like surface during picnics and outings. Prior devices have never fully satisfied the second purpose, their surfaces being too soft and pliable, this leading to problems in fulfilling the first purpose also in that the bag would not provide a semi-rigid internal space for carrying a payload. This invention teaches a new construction and a new method for converting from one purpose to the other.The new construction is both internal; employing three layers, the center layer being of semi-rigid material and, external; in the arrangement of the panels of the three-layered material.The new method of folding employs a stepwise folding of the flat panels into a box-like shape, suitable for maintaining a semi-rigid internal space.
