Abstract: An ovality measurement tool for measurement of ovality of a circumferentially deformable cylindrical element having a cylindrical element support, a sensing element for traversing the circumference of the cylindrical element, which sensing element is movable radially with respect to the cylindrical element, and a readout device for reading the amount of movement of the sensing element as it traverses the circumference of the cylindrical element.

Abstract: A process for application of a protective coating to a steel, concrete, or wooden structure so as to provide protection against corrosion, weathering, or other environmental damage in which the surface to be protected is heated to a temperature in a range of about 75.degree. F. to about 150.degree. F. after which a liquid thermoset primer is applied to the heated material in two stages. The first portion is solidified by heating and then coated with a second portion, forming an uncured liquid thermoset outer primer layer. A melted polymer powder layer is then applied by flamespraying over the uncured liquid thermoset primer layer, forming an intermediate polymer powder layer embedded in the uncured liquid thermoset primer layer.
