Patent ID: 7785670

Claim:
A method utilizing a spray instrumentality for spray-applying to a target surface in a target zone a defined, composite-material layer which is to play a role in defeating a liquid leak from a puncture wound created in the wall of a container holding liquid of a particular character, said method comprising initiating a flow toward the mentioned spray instrumentality of curable, liquid elastomeric body-forming material, at a selectable point, within a range of selectable points, downstream from where said initiating takes place, introducing a flow of plural, liquid-imbiber bead elements which are relevant to the mentioned particular-character liquid, in a user-chooseable manner in relation to said introducing, recognizing that the liquid-imbibing behavior of the bead elements has a dependency on bead-element contact with yet-uncured liquid body-building material, and based on said recognizing, merging the two flows, and following said recognizing and merging, applying the merged flows to a target surface thus to create the desired, defined composite-material layer, which layer takes the form of a body of elastomeric material containing a distribution of the mentioned liquid-imbiber elements.
