Articles and methods are provided for enclosing an elongate substrate. A container is provided which is configured to receive the elongate substrate. A first polymeric sealing material having a first softening point and a first melt viscosity is positioned in the container. A second polymeric sealing material is positioned in the container between the first sealing material and an end of the container. The second sealing material has a second softening point lower than the first softening point and a second melt viscosity lower at a defined temperature than the fist melt viscosity.

Methods and articles for enclosing an elongate substrate using polymeric sealing materials with different softening points and melt viscosities

A closure is provided including a casing part having at least one opening configured to receive an elongate object within the casing part. A sealing chamber defined by the casing part is positioned adjacent the opening so as to receive the elongate object in the sealing chamber and a sealant material is positioned in the sealing chamber. A relatively displaceable wall part of the casing part in provided in various embodiments which communicatively contacts the sealant material and is coupled to another part of the casing part by a flexible hinge part so as to allow movement of the relatively displaceable wall part relative to the other part of the casing. A compression means may be provided for applying a compressive force to the sealant material through the relatively displaceable wall part. In further embodiments a displaceable plunger is provided defining a wall of the sealing chamber and an externally operable shaft threadably engages the plunger so as to displace the plunger to adjust a volume of the sealant chamber.

Sealing device

This invention provides an enclosure for a butt splice of optical fiber cables which includes organizer trays for storing the excess lengths of individual optical fibers. The enclosure and trays provide for access to the individual fibers for splicing or repair.

Electrofit fiber optics butt splice

An electrical connector, particularly an insulation-displacement connector of split-beam design, comprising a metal that at constant temperature has an elasticity of at least 0.8%. This allows the connector to be used with conductors over a large diameter range.

Method of enclosing a substrate within a heat-shrinkable sleeve

A method of environmentally protecting an elongate substrate with a cover and a sealing means comprising a sealing material having an elongation of at least 100% and a compression set at 70.degree. C. of less than 30%, which comprises positioning the sealing means around a portion of the substrate and surrounding the substrate with the cover such that the sealing material provides a seal between the cover and the substrate.

Splice case for optical fibre cable

This invention provides an enclosure for a butt splice of optical fibre cables which includes organizer trays for storing the excess lengths of individual optical fibres. The enclosure and trays provide for access to the individual fibres for splicing or repair.

Electrofit fibre optics butt splice

A telecommunications splice case comprises a flexible sheet that can be wrapped around the splice and optionally further surrounded by a rigid casing. The sheet has a heat-activatable sealing material at its edge and an electrical heater for activation.
