Abstract
Abstract A heat-shrinkable hollow article having one open end affording access to an internal cavity, the wall defining the internal cavity being shaped to provide stop means projecting into the cavity at a position or positions between the open end and the end of the cavity remote from the open end, whereby after heat-shrinking of the article onto a substrate a gap is left between the substrate and the end of the cavity remote from said open end.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A heat-recoverable hollow tubular article having a heat-recoverable wall which defines (a) a relatively large internal cavity, (b) a first open end affording access to the cavity, (c) a second end, and (d) a stop means projecting into the cavity at a position between the first and second ends, said article, when heated to cause complete recovery thereof, recovering to a heat-stable form in which (1) the portion of the wall defining the cavity has recovered to a form which defines a relatively small internal cavity, (2) the portion of the wall defining the stop means has recovered to a heat-stable form which does not project into the relatively small internal cavity, and (3) the portion of the wall defining the second end has recovered to form an open end.
Claim 2
Dependent Claim
130 words
A heat-recoverable hollow tubular article having a heat-recoverable wall which defines (a) a relatively large internal cavity, (b) a first open end affording access to the cavity, (c) a second end, and (d) a stop means projecting into the cavity at a position between the first and second ends, said article, when heated to cause complete recovery thereof, recovering to a heat-stable form in which (1) the portion of the wall defining the cavity has recovered to a form which defines a relatively small internal cavity, (2) the portion of the wall defining the stop means has recovered to a heat-stable form which does not project into the relatively small internal cavity, and (3) the portion of the wall defining the second end has recovered to form an open end.
Claim 3
Dependent Claim
240 words
A process for protecting the end of a cable which comprises (1) positioning over the end of the cable of heat-recoverable hollow tubular article having a heat-recoverable wall which defines (a) a relatively large internal cavity, (b) a first open end affording access to the cavity, (c) a second end, and (d) a stop means projecting into the cavity at a position between the first and second ends, said article, when heated to cause complete recovery thereof, recovering to a heat-stable form in which (1) the portion of the wall defining the cavity has recovered to a form which defines a relatively small internal cavity, (2) the portion of the wall defining the stop means has recovered to a heat-stable form which does not project into the relatively small internal cavity, and (3) the portion of the wall defining the second end has recovered to form an open end; said heat-recoverable article being positioned over the end of the cable so that the end of the cable lies within the relatively large internal cavity and abuts the stop means; and (2) heating the article to cause the portion of the wall defining the internal cavity to shrink into contact with the end of the cable and to cause the portion of the wall defining the stop means to recover to a heat-stable form to leave a gap between the end of the cable and the second end of the article.
