Filed:

Mar 5, 2003

Appl. No.:

10/382018

Inventors:

Travis Harris - Spring TX, US

International Classification:

E04G005/00

US Classification:

182/113000, 182/045000

Abstract:

A safety device and methods for providing fall protection during the installation of roofing panels. A moveable safety handrail system includes a pair of safety rails that are supported in a generally horizontal orientation by a plurality of outrigger assemblies. The outrigger assemblies each include a support portion for support of the rail members and a rolling frame portion that engages the purlins of a rooftop structure in rolling contact. The handrail system also features a braking system that prevents inadvertent movement of the handrail device upon the rooftop understructure.

US Classification:

166193, 251213, 251359

Abstract:

A pluggable seat includes, a first portion, positionable within a tubular, that is receptive to a runnable member seatable thereagainst, a second portion positioned downstream of the first portion, having a radial dimension smaller than a smallest radial dimension of the first portion, and a profile disposed at the second portion configured to increase resistance to extrusion of a runnable member past the pluggable seat in comparison to the same pluggable seat without the profile.

Abstract:

A rupture disc assembly and a float tool incorporating the rupture disc assembly is disclosed. The rupture disc assembly may include a rupture disc assembly comprising a rupture disc, an upper tubular portion and a lower tubular portion, and a securing mechanism for holding the rupture disc between the upper and lower tubular portions. A float tool for creating a buoyant chamber in a casing string may include the rupture disc assembly and a sealing device for sealing the lower end of the casing string, the buoyant, sealed chamber may be created there between. In operation, applied fluid pressure causes the rupture disc to move downward. The rupture disc may be shattered by contact with a surface on the lower tubular portion. Full casing internal diameter may be restored in the region where the rupture disc formerly sealed the casing.
