Abstract: A device for semi-permanently sealing a leaking fluid delivery system comprising generally cylindrical resilient tubing comprising a material that permits delivery through a portion of a fluid delivery system at a first diameter and application to an interior wall of the fluid delivery system at a second diameter when exposed to temperature and pressure gradients, and further configured to undergo a change from the second diameter to a third diameter when exposed to reduced pressure to enable removal of the cylindrical resilient tubing from the fluid delivery system for replacement by a second length of generally cylindrical resilient tubing that permits delivery at a first diameter and application to an interior wall of the at least a portion of the fluid delivery system at a second diameter when exposed to temperature and pressure gradients.

Abstract: An injection molded water soluble golf ball of unitary construction formed entirely from a liquid mixture comprising a non-toxic water soluble filler material mixed with a water soluble thermo setting adhesive material which when combined, injected into the proper sized closed mold cavity under high pressure and heat cured forms a dimpled water soluble golf ball that has substantially the same appearance, weight, size and playing characteristics of a conventional regulation golf ball.
