Abstract: A sealed gas burner for a cooking range has a venturi tube assembly which is attached directly to a range top of the cooking range. A burner cup slidingly and releasably engages a venturi tube of the venturi tube assembly which extends through the range top. A burner cap releasably engages the burner cup and it defines a plurality of burner ports. The burner cup and the burner cap define an annular gas chamber in communication with the burner ports. The burner ports can be cleaned by removing only the burner cap. Additional cleaning of the burner and the range top can be accomplished by removing both the burner cap and the burner cup.

Abstract: A system is described for forming a recycled copper product from at least one copper scrap feedstock source containing at least one contaminant. A pre-determined maximum weight percentage of the contaminant in the recycled copper product is initially established. The weight percentage of the contaminant in the copper scrap feedstock source is then determined. A determination is then made as to whether the weight percentage of the contaminant in the copper scrap feedstock source will exceed the established maximum weight percentage of the contaminant in the recycled copper product. If so, another copper scrap feedstock source is then added to the first copper feedstock source so as to cause the combined copper scrap feedstock sources to have an average weight percentage of the contaminant that does not exceed the established maximum weight percentage of the contaminant in the recycled copper product.

Abstract: An incrementally positionable ball valve for use in the fluid circuit of a refrigeration or air conditioning system which can be remotely controlled by a low amperage control signal is disclosed. The ball valve harnesses the pressurized refrigerant from the fluid circuit in which it is installed as the primary power medium to actuate the valve. A sensor provides feedback to a controller relating to the incremental position of the valve. The controller then controls the operation of the valve in accordance with predetermined criteria. In another embodiment, the ball valve incorporates locator detents so that its incremental position can be determined by an operator manually controlling the valve. In still another aspect of the invention, a restrictor is provided for varying the flow capacity of the valve.

Abstract: The present invention relates to an apparatus and in-situ method for immobilizing mine drainage from spent mine works. This apparatus and preferred method are readily adapted for use in any mine, but particularly well-suited for mines which are located on steep hills or mountain sides having limited infrastructure to permit access for utilities and construction equipment. The present invention utilizes known technology for erecting a bulkhead in the portal of a mine drift, providing a distribution system for controlling drainage of mine water collected behind the bulkhead, mixing the mine water with a constituent to form a slurry, and introducing the slurry into the sealed mine. The present invention has the advantage of neutralizing the mine water to make discharges, if any, acceptable; precipitating dissolved metal out of the mine water within the sealed mine; and further sealing fissures that create seepage from the sealed mine.

Abstract: A refrigerant powered actuated ball valve for use in the fluid circuit of a refrigeration or air conditioning system which can be remotely controlled by a low amperage control signal is disclosed. The actuated ball valve harnesses the pressurized refrigerant from the fluid circuit in which it is installed as the primary power medium to actuate the valve. The valve includes actuation means with a manifold having an inlet port which is in constant fluid communication with a high-pressure side of the fluid circuit. Pressurized refrigerant supplied to the manifold is branched to a series of fluid channels running through the manifold. Exhaust port operators are mounted in conjunction with the manifold to connect the actuation means to the low-pressure side of the fluid circuit and to direct the flow of pressurized refrigerant to either an exhaust port or the manifold.

Abstract: A machine for forming a metallic tubular section in which the tubular section is located, retained, has at least one end formed, filled with fluid that is then pressurized within the tube section, and bend formed into a predetermined shape, all at a single station of the machine. A second station, either coupled with or independent from the first station functions to locate a tube section, retain it, cut off a portion of the tube section, form at least one end of the tube section, and provide for removal of the tube section therefrom. The tube sections are preferably crossover fittings. The present invention further comprises a method of manufacturing a full crossover fitting and a method of manufacturing a half crossover fitting.

Abstract: A valve, such as a compressor or line service valve, for use in refrigeration or air conditioning fluid circuits having an improved flow for improved energy efficiency is disclosed. The valve incorporates a rotary ball member with a 90.degree. fluid passage diameter that is equal to or greater than the diameter of the fluid line that it services. Rotation of a primary actuator stem rotates the ball member to open and close the valve. An annular ball seal provides a seat against which the ball may be positively sealed. A secondary stem is aligned on an alternate axis from the primary stem that is preferably collinear with a fluid line. The secondary stem effectuates a positive engagement between the rotary ball member and the ball seal. A plunger cooperates with locator indentations and a groove in the rotary ball member to center the ball within the valve and align its fluid passage with fluid line connectors.
