Process for sealing cable at fittings

Claim 2

A process for sealing cable at fittings connected to a pressurized environment or the like, comprising the steps of: securing the fitting to a console or the like which is in communication with said environment; pulling a group of cables through said fitting and connecting said cables within said environment; placing a split ring sealing assembly around said cable group and moving said assembly inside said fitting; assembling a split tube around the cable group; attaching a sleeve or container to one end of the tube; forming a dam between and around all of the cables; disposing the tube, with the attached sleeve, within the sealing assembly such that the sleeve surrounds the dam; and, filling the tube with a fluid sealing compound.

Claim 3

A process as defined in claim 1, in which the step of pulling the group of cables is performed after the fitting has been secured.

Claim 4

A process as defined in claim 2 further including the step of positioning a plurality of screws within spaced apertures in the sealing assembly and tightening such screws to insure a good seal.

Claim 5

A process as defined in claim 3 further including the step of applying sealing putty around the cables, and extending a securing means around said sleeve at the point where said sealing putty has been disposed so as to form the dam and thereby prevent downflow of the sealing compound.

Claim 6

A process as defined in claim 1, in which said sealing compound is a polyurethane resin.

Claim 7

Apparatus for providing sealing of an opening in a console or the like through which a group of cables extend into a pressurized environment or the like, comprising: a nipple assembly adapted to surround said group of cables and adapted to be connected to said console or the like; a sealing assembly, including a pair of axially spaced rings and a resilient sealing ring extending between said axially spaced rings, all of said rings being split so that said sealing assembly is adapted to be placed around an already extended group of cables and to be positioned inside said nipple assembly; a sealing-compound-retaining means comprising a tube in two sections, adapted to be placed around said group of cables and thencE to be disposed within said sealing assembly and to be engaged by the resilient sealing ring, and a sleeve attached to said tube and extending below the lower end of said tube; a sealing compound contained within said tube and retained by said tube and attached sleeve so as to surround said group of cables and to provide sealing of said environment.

Claim 8

Apparatus for providing sealing of an opening in a console or the like through which a group of cables extend into a pressurized environment or the like, comprising: a nipple assembly adapted to surround said group of cables and adapted to be connected to said console or the like; a sealing assembly, including a pair of axially spaced rings and a resilient sealing ring extending between said axially spaced rings, all of said rings being split so that said sealing assembly is adapted to be placed around an already extended group of cables and to be positioned inside said nipple assembly; a sealing-compound-retaining means comprising a tube in two sections, adapted to be placed around said group of cables and thencE to be disposed within said sealing assembly and to be engaged by the resilient sealing ring, and a sleeve attached to said tube and extending below the lower end of said tube; a sealing compound contained within said tube and retained by said tube and attached sleeve so as to surround said group of cables and to provide sealing of said environment.

Claim 9

Apparatus as defined in claim 6, in which said nipple assembly includes a nipple and a locking nut, said nipple being adapted to extend through said opening in the console, said nipple being provided with a flange for engaging one side of the console at the opening thereof and said locking nut being adapted to engage the opposite side thereof; and further comprising a locking collar secured to said nipple and having an inwardly extending flange engaging one of said split rings.

Claim 10

Apparatus as defined in claim 6 in which each of said axially spaced rings is split in two places and said sealing ring is split at a place substantially corresponding with one of the two places; and further including circumferentially spaced, aligned apertures in each of the split rings and the sealing ring for receiving screws.

Claim 11

Apparatus as defined in claim 6, in which said sealing compound is a polyurethane resin.

Claim 12

Apparatus as defined in claim 6, in which the upper one of said pair of axially spaced rings has a diameter smaller than the lower one such that the entire sealing assembly can pass into the opening in said nipple except for the lower ring which is stopped at the end of the nipple.
