Patent ID: 7854968

Claim:
A method for establishing a sprayable stream of composite material for spray-applying to a target surface in a target zone to create a defined coating 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, where the target surface is on a side of such a container wall, said method comprising initiating a pair of respective sub-flows of two, precursor elastomeric materials for later blending to create a formed elastomeric body, at a point downstream from where said initiating takes place, introducing a flow of plural, liquid-imbiber beads which are reactive to the mentioned, particular-character liquid, in a user-chooseable manner upstream from where said later blending takes place, merging the flow of liquid-imbiber beads with at least one of the two sub-flows of precursor elastomeric materials, wherein said introducing includes introducing to provide a time-dependant contact interval between the liquid-imbiber beads and a sub-flow for ultimately controlling the speed with which the liquid-imbiber bead-containing composite material reacts to the particular-character liquid, thereafter, blending the two sub-flows, and following said merging and blending, spray-applying the merged and blended flows/sub-flows to such a target surface thus to create the desired, defined composite-material coating which takes the form of a body of elastomeric material containing a distribution of the mentioned liquid-imbiber beads.
