International Classification:

A62C 3100

US Classification:

239566, 239438, 239442, 239447

Abstract:

A remotely operated cutting mode shifting apparatus for use with a decoking tool of the type in which the cutting mode is changed by rotation of a diverter valve plate, has a shifter body adapted for mounting to the decoking tool and a control rod for engaging with the diverter valve plate. It includes a mechanism within the shifter body for rotating the control rod to drive the diverter valve plate to shift the cutting mode of the decoking tool upon release of cutting fluid pressure from the tool.

US Classification:

202241, 202262, 202239, 202268, 239446

Abstract:

A mode shifting apparatus for a decoking tool, a decoking tool and method of operating same. The apparatus includes features to make it rotatably and translationally responsive to changes in pressure of a decoking fluid such that the apparatus is cooperative with the tool and the decoking fluid in a first operating condition to establish a drilling mode with one or more of the tool's drilling nozzles, and in a second operating condition to establish a cutting mode with one or more of the tool's cutting nozzles. In one form, the apparatus includes one or more sets of tandem seals disposed along a component interface within the apparatus or between the apparatus and the tool to help redundantly isolate seizure-sensitive components within the apparatus from the pressurized decoking fluid. In another form, the apparatus includes a gas spring to counteract the forces imposed by the pressurized decoking fluid. In another form, the apparatus includes a manual override connection.

International Classification:

D07B 1/18
D07B 9/00
B64D 17/24

Abstract:

A continuous tensile system is disclosed. The system is braided from individual ropes that form bridle legs, riser, and extension lines in a parachute system. The continuous nature of the braided system allows load sharing between strands and an increased mass efficiency for the breaking system of a payload.
