Abstract: An apparatus for continuous heat treating advancing continuously formed pipe in a restricted space with minimal deformation of the pipe during the heat treatment comprising a pipe feeder; curved rollers for receiving the pipe and advancing the pipe there around. A heat chamber for housing the curved rollers. A heat source for providing heat to the heat chamber and the pipe. A first deforming element for deforming the pipe into a curve for following the curve rollers and for directing the pipe to transverse across the rollers as the pipe is advanced around the rollers. A second deforming means for receiving and deforming the said pipe as it exists from the rollers into a substantial straight line and a take-up roller for receiving the pipe as it comes through the second deforming means.

Abstract: A tubular fence post has a U-shaped cut-out portion to receive a top rail, the upward extension of the fence post walls being bendable over the top rail to secure it. In a second embodiment, one of the upward extensions forms a barb arm that attains a diagonal orientation when bent over the top rail. A shorter upward extension opposite the barb arm has a lock tab bendable over side tabs of the barb arm.
