Abstract: A water conditioner that utilizes ionic flow and selective ionic filtering to control water hardness and/or pH. In some embodiments, the water conditioner includes one or more conditioning cells each having electrodes and a cathode side and an anode side separated by an ion-selective filter. The ion-selective filter is design/configured/selected to pass alkaline earth metal cations and block corresponding carbonate anions. When the electrodes are energized and water is present on the cathode and anode sides of the filter membrane, the alkaline earth metal cations pass from the anode side to the cathode side through the membrane, while the membrane blocks carbonate ions on the cathode side from passing to the anode side. In this manner, alkaline earth metal cations, and water hardness, can be reduced in the anode flow.

Abstract: A thermally activated vent damper assembly for occluding passage of gases in a passageway such as a flue. The assembly includes first and second damper members which are pivotable about a common axis. Coaxial first and second support members which are spaced apart along the common axis support thermally activated biasing members which are attached to the damper members to thereby suspend the damper members within the flue. When heated, the biasing members pivot the first and second damper members about their common axis from a flue closing orientation to a flue opening orientation. The assembly may include a housing mountable to the flue and to which the first and second support members are attached.

Abstract: A thermally activated vent damper assembly for a flue is adapted to be situated in relation to the flue for occluding the passage of gas through the flue. A support member traverses the flue and suspends the damper member across the flue for movement between an open and a closed position. A thermally activated biasing member is operatively coupled between the support member and the damper member to bias the damper member in the open position in the presence of heat and to bias the damper member in the closed position in the absence of heat. The coupling of the biasing member between the support member and the damper member is such that potential sites for frictional inhibition of damper member movement are eliminated. Upon breakage or other failure of the biasing member to apply bias, the damper member defaults to or remains in an open position under the force of gravity, providing for a unique fail-safe feature.

Abstract: A fireplace gas burning assembly for producing a clean burning yellow flame in a chamber is disclosed. The assembly includes at least one means for introducing a substantially vertical flow of a flammable fluid into the chamber. The assembly also includes at least one means for introducing a substantially vertical stream of secondary air into the chamber. The means for introducing a substantially vertical stream of secondary air into the chamber is positioned such that the stream of air and flow of flammable fluid intersect such that when ignition occurs a yellow clean burning flame will be produced.

The housing has a first housing wall, a second housing wall and intermediate walls connecting the first and second housing walls. The first housing wall has an opening therein to receive combustion chamber effluent. The second housing wall has an opening for emission of combustion chamber effluent which is adapted for communication with the flue of the fireplace assembly for exhaust of the combustion chamber effluent from the fireplace assembly.

Abstract: An assembly is disclosed for enhancing the aesthetics of a gas fireplace. The assembly includes an elongated burner tube which is laterally disposed within the combustion chamber of the fireplace and which includes discharge ports which are inwardly oriented with respect to the combustion chamber. A tray adjoins the front side of the burner tube and may support lava rocks or the like for hiding the burner tube from view. A gap is defined between the floor of the combustion chamber and the bottom surface of the tray so that secondary air can travel from the front end of the combustion chamber towards the burner tube. A support adjoins the rear side of the burner tube and includes an inclined surface facing the burner tube. An emberizing material such as mineral wool is supported by the inclined surfaces. Ignition of the burner tube causes flames to be directed rearwardly and to impinge upon the emberizing material, causing it to glow.

Abstract: Method and gas burner assembly for producing among the arrangement of non-combustible logs, and essentially yellow flame pattern with substantially low levels of carbon monoxide production. In general, method hereof employs a gas burner assembly having one or more burner each having a plurality of gas jets. The burner assembly is disposed between the combustion chamber of fireplace enclosure which contains a predetermined volume of combustion chamber air which is continuously provided from outside of the combustion chamber. Non-combustible fireplace logs are arranged above the gas burner assembly so as to provide one or more flow paths between the burner and adjacent logs, for allowing free flow of combustion chamber air through the flow paths and about the burners. Flow of gas is provided through the burners so that the gas flows out of the gas jets and mixes with the combustion chamber air about the jets of the burner.

Abstract: The improved incinerator apparatus of the present invention is particularly applicable in the purification of air contaminated with volatilized solvents, and functions through the use of a venturi within the assembly which imposes a low pressure drop while simultaneously obtaining a high degree of turbulence and mixing of the primary fuel with the effluent waste gas being incinerated. The incinerator apparatus of the present invention comprises a solvent vapor conduit for directing a stream of air containing solvent vapors in a first longitudinal direction to be redirected into a venturi. The venturi is preferably disposed within the solvent vapor conduit. A supplemental fuel injector is disposed within the central bore of the venturi to provide gaseous fuel through the central bore to comingle with the solvent vapor containing air for ignition, to provide a sustainable flame for burning the volatilized solvent in the air and thereby to provide air free of such solvent vapors.

Abstract: The improved burner unit of the present invention is designed for use in relatively lower oxygen and/or lower pressure drop environments. The improved burner unit of the present invention comprises a burner base disposed at the bottom of the burner trough. A pair of mixing plates having aeration openings therein are attached on opposite sides of the burner base. The mixing plates include a lower flange for attachment to the burner base and a mixing plate body extending upwardly from such lower flange. The mixing plate body forms the sides of the burner trough and includes an outwardly protruding bulge at the center of the mixing plate. The burner unit also includes side flanges disposed on and extending from the sides of the mixing plate for engagement with like side flanges on like mixing plates to form a burner of the desired length. In preferred embodiments, the bulge in the side of the mixing plate body is generally parabolic in shape as viewed from the trough of the burner.
