If the furnace is a cross-fired regenerative furnace, the method and apparatus for introducing oxygen enriched air can be mounted to at least one regenerator for the furnace.

Abstract: A method for melting meltable stock, such as glass includes a melting furnace (10) heated via a burner flame (25,29) generated by a burner port, through which fuel and oxidizer are supplied, a fuel-rich gas stream introduced into the furnace downstream from the burner port via at least one substoichiometrically operated burner (20,22) and/or a fuel or fuel mixture being introduced into the furnace downstream from the burner arrangement via at least one fuel nozzle, and a oxygen containing gas stream being introduced into the furnace downstream from the at least one substoichiometrically operated burner and/or the at least one fuel nozzle. A furnace device is also provided.

Abstract: A spray dispenser is provided, the spray dispenser comprising a container for holding a liquid to be dispensed and a dispensing assembly for extracting liquid from said container, the dispensing assembly comprising a pressure-relief valve for release of excessive pressure in the container and a filter arranged to permit egress of gas through the filter, inhibit egress of liquid from the container and to inhibit ingress of contaminants into the container through the pressure relief valve. A dispensing assembly for use is a spray dispenser is also provided.

Abstract: A method is provided to facilitate combustion in a furnace having at least one burner, an inlet, an outlet, and sidewalls and a crown defining a combustion chamber for the furnace, the method consisting of identifying a region of the combustion chamber where a furnace atmosphere therein requires an increase in oxygen for combustion in the furnace atmosphere, and providing fresh oxygen to the region at a controlled flow rate for the combustion, wherein the fresh oxygen provided causes circulation of the furnace atmosphere for combining existing gases and existing oxygen of the furnace atmosphere with the fresh oxygen provided to the region for combustion.

Abstract: A burner for use in a combustion chamber of a furnace or a forehearth includes a gas delivery member for delivering a gaseous oxidant, a fuel delivery member for delivering a fuel and having a portion disposed at an interior of the gas delivery member and offset from a longitudinal axis of the gas delivery member, and a flange assembly mechanically associated with the gas and fuel delivery members, the flange assembly adapted for rotational movement to releasably secure the gas and fuel delivery members with respect to each other to provide a flame footprint at a select location in the combustion chamber.

Abstract: Methods relate to tubulars that may be part of a tubular string for isolating one or more zones within a wellbore. In one embodiment, the tubular string includes a first expandable zone isolation unit disposed on a first side of a zone to be isolated, a second expandable zone isolation unit disposed on a second side of the zone to be isolated, and a perforated tubular disposed in fluid communication with a producing zone. The tubular string may be expanded using an expansion assembly having a first expander for expanding the first and second expandable zone isolation units and a second expander for expanding the at least one perforated tubular. Tags or markers along the tubular string may indicate locations where expansion is desired such that connections or connectors between joints are not expanded.

Abstract: A burner and method of combustion for a furnace or a forehearth includes a gas delivery member and a fuel delivery member having a portion thereof disposed at an interior of the gas delivery member and offset or angled from a longitudinal axis of the gas delivery member to provide gaseous oxidant and fuel flows for combustion.

Abstract: A glass melting furnace has a gas inlet positioned proximate to a charging section oxy-fuel combustion region to introduce gas into the region and to at least partially displace gas having a partial pressure of alkali vapor from the region, and optionally a gas outlet is adapted to provide an exit for a volume of furnace atmosphere. A method for reducing alkali vapor corrosion of glass furnace refractory structures includes providing a gas inlet proximate to the oxy-fuel combustion region; introducing a volume of gas from the inlet into the region, displacing a volume of gas having a partial pressure of alkali vapor from the region; and, optionally providing a gas outlet adapted to provide an exit for a volume of furnace atmosphere.

Abstract: A method of lining a bore section, the method comprises providing a first tubing section and an expandable thin-walled second tubing section. The first tubing section is run into a section of a bore. The second tubing section is then run into the bore section, within the first tubing section, and expanded to a larger diameter, such that the bore section is lined by at least two tubing sections.

Abstract: A system 100 for scan testing at least two substantially identical modules 140 and 150 within an integrated circuit is provided. The system 100 includes a first module 140 to receive and process scan input and produce a first scan output. The system 100 includes a second module 150 substantially similar to the first module 140. The second module 150 receives and processes scan input and produces a second scan output. The system 100 also includes a first component 180 to receive the first and second scan outputs and to produce a first output. The first output is used to determine whether the first and second modules 140 and 150 are functioning properly.

The dispersants are thought to be pyrophosphates.

Abstract: A system for testing input characteristics of an integrated circuit device includes an integrated circuit device. The integrated circuit device includes, an input pad, an output pad, an input register, and a data register. The input register receives an input value from the input pad and communicates the input value to a portion of the integrated circuit for processing when the integrated circuit is not in test mode. The data register receives a test value from the input register and communicates the test value to the output pad when the integrated circuit is in test mode.

Abstract: The present invention relates to methods and apparatus for expanding tubulars in a wellbore. In one aspect of the invention, an expansion tool with hydraulically actuated, radially expandable members is disposed on a string of coil tubing. In another aspect of the invention the apparatus is utilized to expand a tubular lining a lateral wellbore into contact with a window of a larger tubular lining a central wellbore.

Abstract: The present invention provides methods and apparatus for cutting tubulars in a wellbore. In one aspect of the invention, a cutting tool having radially disposed rolling element cutters is provided for insertion into a wellbore to a predetermined depth where a tubular therearound will be cut into an upper and lower portion. The cutting tool is constructed and arranged to be rotated while the actuated cutters exert a force on the inside wall of the tubular, thereby severing the tubular therearound. In one aspect, the apparatus is run into the well on wireline which is capable of bearing the weight of the apparatus while supplying a source of electrical power to at least one downhole motor which operates at least one hydraulic pump. The hydraulic pump operates a slip assembly to fix the downhole apparatus within the wellbore prior to operation of the cutting tool. Thereafter, the pump operates a downhole motor to rotate the cutting tool while the cutters are actuated.
