Abstract
Abstract A method of providing a dam in a loading coil case for the blocking of an encapsulant solutions penetration into the cable beyond a desired distance by inserting, via a hypodermic needle, a quantity of encapsulant activator at the desired site of a dam. The encapsulant upon contacting the activator jells very rapidly preventing the remaining encapsulant from draining into the cable.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
66 words
In a method of applying a water repellant substance into a loading coil container including a protruding cable stub; the step of: injecting a polyurethane system activator through the container a predetermined distance into the cable, thereafter pouring into said container in a single operation a low viscosity polyurethane, thereby forming a dam at said system activator and polyurethane interface and moisture sealing said container simultaneously.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
22 words
A method of applying a water repellant substance as claimed in claim 1, wherein said injecting is done using a hypodermic needle.
Claim 4
Dependent Claim
26 words
A method of applying a water repellant substance as claimed in claim 1 further including the step of curing the low viscosity polyurethane above said dam.
