  • Patent number: 6994819
    Abstract: An apparatus for rerounding plastic pipe includes a housing having a pipe passage extending therethrough. The housing has a moveable outer frame top positionable between an open position and a closed position to enclose a pipe to be rerounded. A pair of opposing jaws are positioned within the housing and on opposite sides of the pipe passage and have a generally symmetrical configuration with respect to one another. A drive mechanism is connected with respect to at least one of the jaws for compressing the jaws with respect to each other resulting in compression of the pipe to be rerounded.

  • Patent number: 6146709
    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 F. to about 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.
