Filler assembly for cable gland
DCFirst Claim
1. A filler assembly for filling with curable liquid material a cable gland, the cable gland having a plurality of cores of at least one cable extending therethrough, the assembly comprising:
- (a) a dispenser apparatus for a curable liquid material, the apparatus comprising;
a body adapted to define at least one first chamber for accommodating a first component of a curable liquid material, and at least one second chamber for accommodating a second component of said curable liquid material and adapted to communicate with at least one said first chamber to enable mixing of said first and second components to initiate curing of said curable liquid material;
at least one first barrier apparatus for temporarily preventing mixing of said first and second components;
at least one elongate dispenser apparatus adapted to communicate with at least one said second chamber and to dispense said mixed curable liquid material therefrom between a plurality of cores of at least one cable; and
at least one second barrier apparatus for temporarily preventing passage of said curable liquid material from the or each said second chamber to at least one said dispenser apparatus; and
(b) at least one flexible barrier member having at least one respective aperture therethrough adapted to stretch to engage a plurality of cores of a cable to provide a barrier to passage of said curable liquid material along said cores.

Abstract
A dispenser apparatus (2) for a curable liquid material is disclosed. The apparatus comprises a flexible bag (8) defining a first compartment (10) for accommodating a first component of a curable liquid material, and a second compartment (12) for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp (14) temporarily prevents mixing of the first and second components, and an elongate nozzle (16) communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp (18) temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

14. A method of filling a cable gland with curable liquid material, the method comprising:
-
using a filler assembly that includes; (a) a dispenser apparatus for a curable liquid material, the apparatus comprising;
—a body adapted to define at least one first chamber for accommodating a first component of a curable liquid material, and at least one second chamber for accommodating a second component of said curable liquid material and adapted to communicate with at least one said first chamber to enable mixing of said first and second components to initiate curing of said curable liquid material; at least one first barrier apparatus for temporarily preventing mixing of said first and second components; at least one elongate dispenser apparatus adapted to communicate with at least one said second chamber and to dispense said mixed curable liquid material therefrom between a plurality of cores of at least one cable; and at least one second barrier apparatus for temporarily preventing passage of said curable liquid material from the or each said second chamber to at least one said dispenser apparatus; and (b) at least one flexible barrier member for having at least one respective aperture therethrough adapted to stretch to engage a plurality of cores of a cable to provide a bather to passage of said curable liquid material along said cores; locating at least one said barrier member in the cable gland; and locating an outlet of at least one said dispenser apparatus in said cable gland and dispensing curable liquid material therefrom so as to expel air from the cable gland. - View Dependent Claims (15)

- 16. In a cable gland through which a bundle of cores of a cable extend and that is filled with a curable material so as to block the passage through the gland of gases from an explosion, the improvement wherein the gland defines a resin well at the bottom of which resides a flexible barrier member having an elastomeric membrane in a central portion thereof, the flexible barrier member sealing the bottom of the resin well except for an aperture through the membrane through which the cores extend, the aperture being smaller than the bundle of cores so that the cores stretch the aperture to fit tightly around the bundle, and wherein prior to curing the curable material is a liquid when it is placed in the well that flows in between the cores and around the bundle of cores.
