Abstract: Novel methods for sealing a closure member to a substrate make use of pressure generated in a chamber to create and/or maintain a seal between a closure member and a substrate. The chamber has a flexible wall which is urged towards the substrate by the pressure. Where the substrate has a hollow interior which is maintained at superatmospheric pressure, e.g. a pressurized telephone cable, a fluid passage is preferably provided between the interior and the closed chamber after the seal has been formed, thus taking the closure member out of peel with the substrate. A preferred closure member is an inflatable bag which has sealing material on selected portions of one surface thereof, so that it can be wrapped around the substrate to form a hollow enclosure around the substrate. After placing a restraining means around the wrapped closure member, the closure member is inflated, thus improving the seal around the enclosure.

Abstract: The invention relates to a novel case for enclosing a short length of at least one elongate substrate, especially a cable splice. The case has a wrap-around body section and end sections comprising deformable sealing members which in use are deformed into a configuration in which an increase in pressure within the case increases the forces maintaining the sealing members in contact with the substrate. Preferably the case includes heating means which is used to heat the sealing members and to activate a hot melt adhesive placed thereon.

Abstract: A protective sleeve for a cable which is to be pressurized internally for leak-detection and cable preservation has a seal near an end thereof through which one or more cables pass into the interior of the sleeve. The seal has a lip formed about the periphery of its inner face, subject to pressure within the sleeve and extending radially and longitudinally from the face to engage the interior surface of the sleeve or sealing compound placed thereon. Pressure within the sleeve forces the lip against the interior surface of the sleeve to form a gas-tight seal regardless of reasonable variations in the internal diameter of the sleeve. One or more lamellations back up the inner, sealing face of the seal and engage each cable passing through the seal. The seal is conveniently made in two pieces for fitting about a continuous cable, and the sections of the seal are joined by tongue and groove arrangements or enlarged sealing surfaces at the joints.
