Abstract
Abstract An apparatus and method for protection of a substrate, e.g. an electrical contact. The apparatus comprises a support member and an encapsulant which has a cone penetration value of 100 to 350 (10 -1 mm) and an ultimate elongation of at least 200%, and preferably an elastic modulus of less than 10' dynes/cm 2 . The encapsulant and the substrate are pressed together so that the encapsulant is deformed into close and conforming contact with the substrate. Preferably at least part of the deformation is elastic deformation.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
37 words
Apparatus comprising a support member and an encapsulant, the encapsulant being adherent to the support member and having a cone penetration value of 100 to 350 (10 -1 mm) and an ultimate elongation of at least 200%.
Claim 2
Dependent Claim
37 words
Apparatus comprising a support member and an encapsulant, the encapsulant being adherent to the support member and having a cone penetration value of 100 to 350 (10 -1 mm) and an ultimate elongation of at least 200%.
Claim 3
Dependent Claim
38 words
Apparatus as recited in claim 1, wherein said support member comprises a plurality of individual open containers, which are connected to each other by a flexible connecting means, and each of which contains a separate mass of encapsulant.
Claim 4
Dependent Claim
79 words
An apparatus as recited in claim 1, wherein said support member is a flexible matrix which comprises a plurality of open interstices, the interstices having an average volume of less than 0.01 inch 3 , and wherein said encapsulant comprises a plurality of interconnected segments which lie within the interstices of the matrix; the matrix and the impregnant being such that, when the article is stretched, the matrix reaches its ultimate elongation before the impregnant reaches its ultimate elongation.
Claim 5
Dependent Claim
15 words
An apparatus according to Claim 3, wherein the matrix is an open cell polymeric foam.
Claim 6
Dependent Claim
57 words
Apparatus as recited in claim 1, wherein said support member comprises: a) an electrical connector which is adapted to receive electrical wires and electrically connect electrical wires received therein; and b) an insulating member adapted to surround and retain said connector; said encapsulant being disposed within at least one of said electrical connector and said insulating member.
Claim 7
Dependent Claim
16 words
Apparatus as recited in claim 1, wherein at least part of said support member is heat-recoverable.
Claim 8
Dependent Claim
25 words
Apparatus as recited in any one of the preceding claims wherein the encapsulant has an elastic modulus of less than 10 7 dynes/cm 2 .
Claim 9
Dependent Claim
23 words
Apparatus as recited in any one of the preceding claims wherein said cone penetration value is 150 to 350 (10 -1 mm ).
Claim 10
Dependent Claim
20 words
Apparatus as recited in any one of the preceding claims wherein said encapsulant has an elongation of at least 500%.
Claim 11
Dependent Claim
17 words
Apparatus as recited in any one of the preceding claims wherein the encapsulant is an oil-extended polyurethane.
Claim 12
Dependent Claim
78 words
Apparatus as recited in claim 10, wherein the encapsulant has been prepared by gelling a liquid mixture comprising 20 to 40% of curable polyurethane precursor materials and 80 to 60% of a mixture of mineral oil and vegetable oil in which the ratio by weight of mineral oil to vegetable oil is 0.7 to 2.4; the percentages being by weight based on the total weight of the polyurethane precursor materials and the mixture of mineral and vegetable oils.
Claim 13
Dependent Claim
23 words
Apparatus as recited in claim 1 or 2, which comprises a force member for maintaining the encapsulant in compressive contact with a substrate.
Claim 14
Independent Claim
40 words
A method of protecting a substrate which comprises pressing together the substrate and an apparatus as recited in any one of the preceding claims, so that the encapsulant contacts the substrate and is deformed into close and conforming contact therewith.
