  • Patent number: 5671727
    Abstract: A gas fireplace has a set of artificial logs. The logs rest on top of a burner. The burner is formed from top and bottom metal sheets. The sheets are sealed together around a channel matched generally to the prospective position of the logs. A gas orifice feeds gas into the channel, while gas ports in the top sheet release the gas. The gas ports are positioned to match the final position of the logs. The channel is formed by creating a depression in the bottom sheet using a press with a general purpose stamping die moving in the pattern of the channel, or a single hit special purpose die, or a rolling die moving in the pattern of the channel, or by the bottom sheet being moved across a stationary rolling or beading die in the pattern of the channel. Secondary air holes feed air through the burner adjacent to the channel and the gas ports.

  • Patent number: 5267552
    Abstract: A direct vent gas fireplace has a firebox surrounded by an enclosure. The enclosure has an inclined surface between the top, rear and sides. The surface is inclined at approximately 45 degrees and has an exhaust opening. The firebox has an inclined surface parallel to the inclined panel and has an aperture in each side of the firebox. A duct connects each of the apertures to the exhaust opening. A heat exchanger lies between the inclined surfaces in line with the duct. The surface has a gap in it which connects through an air combustion conduit to the bottom of the firebox. The conduit may be pre-formed. An angle adaptor has an inner cap over the exhaust opening and an outer cap over the inner cap and the gap. The adaptor may be mounted vertically or horizontally. Alternatively, an inclined plate may be placed over the inclined surface with a hole concentric with the opening and of greater area. A first wall of a double walled vent duct may enclose the opening, while the second wall encloses the hole.

  • Patent number: 4619706
    Abstract: A di-phase stripping composition is disclosed wherein an aqueous phase having a non-aqueous solvent phase dispersed therein is employed to provide significantly improved effectiveness to remove a wide variety of organic coatings from substrates coated therewith. The aqueous phase preferably includes alkaline components and the organic solvent phase comprises a glycol phenol ether or ethoxylated furfuryl alcohol alone or in combination. Other additives can be used effectively to improve the stripping action such as surfactants, chelates and/or sequesterants and dispersants.
