Claim 5

Apparatus having at least one cable passing therethrough for preventing moisture and other contaminants from entering a cable housing, said apparatus comprising first and second halves each having first and second longitudinal edges, said first and second halves forming a first inner chamber when assembled for permitting at least one cable to pass through said inner chamber, first means for securing said first and second halves along the first longitudinal edges of said first and second halves, second means for securing said first and second halves along the second longitudinal edges of said first and second halves, selectively removable means along a first end surface of said apparatus so as to permit at least one cable to pass therethrough, and means made from a synthetic material for filling the space surrounding the cable within said first inner chamber so as to prevent passage of contaminants through said apparatus, the outer surface of said synthetic material conforming to the contour of the inner surface of said first chamber, said synthetic material having at least one set of concentric perforations cut therethrough defining a plurality of annular layers which are secured to each other at predetermined intervals, and each set having at least one radial perforation so as to permit removal of one or more selected ones of said annular layers.

Claim 6

The apparatus of claim 3 wherein said first securing means comprises an eye-hook shaped cross-section member integral with and running along the first longitudinal edge of said first half, and a rod shaped cross-section member integral with and running along the first longitudinal edge of said second half for insertion into the eye-hook shaped cross-section member running along the first longitudinal edge of said first half to lock said first and second halves at their first longitudinal edges.

Claim 7

The apparatus of claim 4 wherein the second securing means comprises a tab integral with and running longitudinally along the second longitudinal edge of said second half including a plurality of apertures spaced at predetermined intervals along said tab, and a tab integral with and running along the second longitudinal edge of said first half, a plurality of projections spaced at intervals along said second longitudinal edge of said first half, each projection being substantially aligned with said apertures when said first and second halves are assembled, each projection comprising first and second prongs, having oppositely sloped shoulder sections spaced apart and outward from the tab member to snap into said rectangular aperture to lock said second longitudinal edges of the first and second halves, and a long nose section extending outward from the sloped shoulder section for directing the spaced prongs toward each other when said second longitudinal edges are locked to disengage the second longitudinal edges of the first and second halves.

Claim 8

The apparatus of claim 5 wherein said second half comprises a first ridge running longitudinally along its inner surface and spaced apart from the aforesaid rod shaped cross-section member and projecting outwardly from said second half, and said first half comrises a first trough running longitudinally along its surface and spaced apart from the aforesaid eye-hook shaped cross-section member, said first ridge mating with said first trough when said first and second halves are assembled.

Claim 9

The apparatus of claim 6 wherein said first half comprises a second ridge running longitudinally along its inner surface and spaced apart from said plurality of spaced apart prong projections and projecting outwardly from said first half, and said second half having a second trough running longitudinally along its surface and spaced apart from the aforesaid tab having a plurality of apertures, said second ridge mating with said second trough when said first and second halves are assembled.

Claim 10

Apparatus having at least one cable passing therethrough for preventing moisture and other contaminants from entering a housing for said at least one cable, said apparatus comprising: a first end having one or more end plates, each end plate having a plurality of perforations, said perforations defining a plurality of selectively removable sections to permit one of said cables to pass therethrough, a compliant synthetic material for filling the space between said inner surface of said apparatus and said one or more cables comprising an outer surface which is shaped to conform to the contour of the inner surface of the apparatus, a plurality of perforations cut through the compliant material to define a plurality of selectively removable annular layers, said layers being joined to one another at predetermined intervals, and a radial perforation through all of said layers, providing access to said layers for their selective removal and for installing said material as a jacket around said at least one cable.

Claim 11

Apparatus having at least one cable passing therethrough for preventing moisture and other contaminants from entering a housing for said at least one cable, said apparatus comprising: a first end having one or more end plates, each end plate having a plurality of perforations, said perforations defining a plurality of selectively removable sections to permit one of said cables to pass therethrough, a compliant synthetic material for filling the space between said inner surface of said apparatus and said one or more cables comprising an outer surface which is shaped to conform to the contour of the inner surface of the apparatus, a plurality of perforations cut through the compliant material to define a plurality of selectively removable annular layers, said layers being joined to one another at predetermined intervals, and a radial perforation through all of said layers, providing access to said layers for their selective removal and for installing said material as a jacket around said at least one cable.
