Abstract: A water stopping configuration of linear members, includes a liquid water stopping material which is cured after the liquid water stopping material is penetrated into interstices between the linear members bundled together. The water stopping material is a magnetic fluid. The water stopping material is cured in a condition that a magnetic field is applied to the water stopping material from the outside of a covering member which covers an outer periphery of bundled portions of the linear members having the water stopping material penetrated therein so as to gather the water stopping material at a predetermined portion within the covering member.

Abstract: Submersible cables that are placed in a body of fluid such as water or other fluids such as chemicals or sewage often require a takeoff to be added to the submersible cable wherein a window is cut in the exterior insulation of the submersible cable or parent trunk exposing interior wires or fiber optical cables or tubes and the like.

Abstract: This invention discloses a method and apparatus for waterblocking wire-to-wire connections in a cable using an arrangement of seals. Lead-in transmission lines are slid through a multiple-aperture seal to produce a compression seal between the transmission lines and the seal and the trailing transmission line is slid through a single-aperture seal to produce another compression seal. A piece of constrictive tubing is slid over the first seal before splicing the wires in the lead-in and trailing transmission lines together. The tubing then is positioned over both seals to produce a compression seal between the tubing and the seals to form a waterblock in the area defined by the two seals containing the splice.

Abstract: A communications cable for use in buried environments in an outside plant includes a core (22) comprising at least one transmission medium and a mechanically strengthened, thermal resistant barrier layer (40) disposed about a plastic tubular member (23). A metallic shield (32) and a plastic jacket (36) are disposed about the barrier. The barrier layer may comprise a tape (41) which is made of a material such as woven glass or an aramid fibrous material, for example, which is resistant to relatively high temperatures, which has suitable strength properties in all directions and at elevated temperatures and which is characterized by properties which cause the barrier layer to impede the passage therethrough of particles which are sufficiently large to cause damage to the core. In a preferred embodiment, the thermal barrier layer also includes provisions for preventing the longitudinal flow of water within the cable.

Abstract: Described is a fiber optic distribution cable having increased flexibility despite the presence of a metallic shield. The shield is a metal tape having dense transverse corrugations. Flexibility also arises from the use of multiple strength members and filaments rather than a single tensile strength member. Such flexibility is highly useful when routing the cable through distribution pedestals.

Abstract: A sealing arrangement having a pre-sealing element and a pourable sealing compound. The sealing arrangement is intended for use in electrical cables where several insulated conductors are enclosed within an insulating hose. To achieve the desired moisture-resistant sealing effect with minimal expenditure of time and material, and to avoid damage to the cable and/or conductors, the pre-sealing element is in the form of an elastic sheath which encloses all the individual conductors at a pre-set location. The sheath comprises a tubular portion which tightly encloses the conductors, pressing them together, and a funnel-shaped portion joined with it, which fits tightly against the wall of the insulating hose.

The termination fitting also includes an annular dielectric plug which concentrically surrounds the inner conductor. The plug is resiliently compressible to seal against the inner conductor under a radial pressure exerted upon the plug and to release itself when the pressure is removed. A holding device is detachably mounted to hold the plug in a sealing position and also to form an airtight seal with the shroud means. The holding device engages one axial side of the plug to compress it against an abutment surface and opposing radial surfaces of the plug and device also apply a radial pressure to the plug.
