Grout Bag Deployment Pallet
US Patent:
5201610, Apr 13, 1993
Filed:
Feb 7, 1991
Appl. No.:
7/651763
Inventors:
Steven E. Mansfield - Houston TX
Neil A. Stagg - Tinamba, AU
Neil A. Stagg - Tinamba, AU
Assignee:
Diverless Systems, Inc. - Houston TX
International Classification:
F16L 104
US Classification:
405172
Abstract:
An apparatus and method for placement and deployment of grout bags which, when deployed by filling with grout, act as supports for subsea pipelines or structures. The apparatus includes a pallet to which a collapsed grout bag is attached for placement, an alignment member, and a manifold assembly for distributing grout to multiple bags or compartments. The alignment member is abutted against the subsea pipeline or structure to assure proper placement of the grout bag beneath the pipeline or structure. The pallet base structure permits level deployment of the pallet on sloping seabeds. The pallet base structure includes legs and brace members which are specially designed to suit the seabed conditions at the installation site. The length of the pallet legs depends upon the relative softness of the seabed, with longer legs providing frictional support as they embed themselves into the seabed. Short legs provide support for the pallet on relatively hard seabeds by resting on the seabed with minimal embedding.
Lap Siding Installation Tool
US Patent:
2001003, Nov 1, 2001
Filed:
Apr 17, 2001
Appl. No.:
09/836563
Inventors:
Steven Mansfield - Houston TX, US
International Classification:
G01D021/00, B23Q003/00
US Classification:
033/647000
Abstract:
The lap siding installation tool is a reusable tool that allows one person to easily handle and install horizontal lap siding on the side of a house or other similar structure. The preferred embodiment of this invention is a simple squared “Z” shaped bracket with spring mechanism that will grip the lower edge of the siding board to be installed. The upper part of the tool provides a “ledge” or “lip” on the backside of the board which will rest on the upper edge of a previously installed board. This “ledge” is in a defined position above the lower edge of the siding board to be installed such that a consistent overlap of the boards is maintained per the lap siding manufacturer's specifications. The board is then fixed to the structure in two (2) places along its upper edge, normally by nails or screws. The tools can then be easily removed by pulling outward on the lower edge of the board a small distance allowing the tools to be pulled downward off of the board.
