Abstract: A heater for heating turbine exhaust gas (TEG) flowing in a downstream direction through a duct formed by sets of opposing side walls is described. A flame shield has first and second plates which extend symmetrically with respect to a horizontal center line substantially across the duct, diverge in the downstream direction, and terminate in plate edges which are spaced from proximate duct side walls. Each plate defines spaced-apart, first and second slits which communicate an upstream side of the plate with a downstream side thereof. The slits are spaced from the center line and from the plate edges. A heating gas supply pipe extends parallel to the center line across the duct and has a plurality of spaced-apart orifices that face in a downstream direction and are in flow communication with the downstream side of the plate.

Abstract: A device for fastening down one section of a strap, cord or the like is disclosed herein. This device which is especially suitable for use in the installation of solar panels includes a base member to be fixedly attached to a given support structure, for example a roof, and a cap disengageably connected with the base member in a predetermined way. The base and cap include confronting surface segments which cooperate with one another for engaging and retaining the strap or cord section in a fixed position along a path having a plurality of bends, preferably four 90.degree. bends.

Abstract: A solar panel assembly is disclosed herein and includes a solar panel arrangement having a main body which defines internal passageways, between inlet and outlet headers, a corrugated glazing sheet located on the top side of the panel body and at least one but preferably two corrugated support sheets located under the panel body. The assembly also includes a header cover on each end of the panel which, in part, encloses a corresponding one of the headers and which, in part, nests against the corrugated glazing sheet and one of the corrugated support sheets.
