Abstract: A lock and pin for the structural and fluid tight repair of cracks not amenable to high temperature repairs or synthetic material patches. Fluid tight pins and locks seal the crack while one or more locks prevent the crack from growing. These repairs need to endure the remaining life cycle of the machinery part while withstanding all the strain, pressure, heat and expansion and contraction of the part before the crack(s) were formed. Often these cracks evolved due to engineering design flaws that will require even greater strength from these areas than when new.

Abstract: In a system for stabilizing a wall, especially a masonry wall (10), movement away from the wall of a rigid member (30) is prevented by a thrust rod (70) that is anchored to joists associated with the wall.
