Abstract: A gas burner for a fireplace includes a rectangular, unitary pan which is fabricated from a generally rectangular single sheet metal panel. Prior to forming the panel into the pan, an inlet tube hole and gas ports are machined into the panel. Assembled to the unitary pan is a gas inlet tube with an air adjustment sleeve assembled thereto. An optional baffle may be used and the purpose of the baffle is to reduce the back firing of gas. The fabrication steps for converting the flat sheet metal panel into the unitary pan involve forming first and second long edges with specific bend geometries and then folding the panel so as to bring those formed edges into alignment with each other. Those formed edges are then crimped together. Once this is completed, each shorter side edge is then folded to itself and crimped so that on three sides of the unitary pan there are crimped seams which are leak-free and along the fourth side there is a fold.

Abstract: An acoustical panel for use in sound reduction in connection with air compressors and similar equipment includes two oppositely disposed layers of synthetic film material which in the preferred embodiment is polyvinychloride and an intermediate layer of acoustical insulation material disposed between the two outer layers wherein the preferred material for the intermediate layer is fiberglass. The acoustical panel is made in one embodiment by adhesively bonding the first outer layer of synthetic film material to one side of the intermediate layer and then adhesively bonding the other outer layer of synthetic film material to the opposite side of the intermediate layer. Once the adhesive bonding is completed, the outer peripheral edges of each outer panel are placed in abutment and heat-sealed so as to encase the intermediate layer.
