Patent number: 6799080Abstract: The present invention provides an automated configurable control system (CCS) for a manufacturing process system, which permits a user to address menus on screen images for initially configuring the process, and for subsequently rapidly adding, modifying, and deleting components and control signals, without revising software programs. The control system utilizes a configuration tool for automatically providing a configuration database file from data inputted by a user into the CCS. A deployment tool automatically downloads the configuration database file to a SCADA application responsive thereto for defining the system, monitoring the status of the processing system, and displaying screen images. The deployment tool also provides the data via a download application to a PLC application for defining the objects and logic of the processing system.Type: GrantFiled: June 12, 2003Date of Patent: September 28, 2004Assignee: The BOC Group, Inc.Inventors: Mark W.

Patent number: 6769310Abstract: A flow-indicating device is provided, comprising a tubular body adapted to direct a flow therethrough. The body has opposed ends, with one end being a downstream end, and has a flow element disposed therein. A shaping block is operably engaged with the body so as to form a constricted portion between the ends, the constricted portion of the body defining a constricted orifice having a downstream side. The constricted orifice is configured to prevent the flow element from passing therethrough. The flow element is disposed on the downstream side of the constricted portion and is configured to engage the constricted orifice when the flow is below a flow rate and to move toward the downstream end of the body as the flow increases over the flow rate to thereby indicate the flow through the body.Type: GrantFiled: June 10, 2002Date of Patent: August 3, 2004Assignee: The BOC Group, Inc.Inventor: Stephen John Carlson

Patent number: 6761109Abstract: An apparatus and method are provided for mixing a gas and a liquid to produce a gaseous vapor of the liquid that is substantially free of droplets. Gas, e.g., carbon dioxide, is divided into first and second streams. The first stream is combined in an atomization zone with the liquid, e.g., acetic acid, to form an atomized mixture of the gas and liquid. This atomized mixture is then contacted with the second gas stream in a mixing zone within a mixing/separation chamber in which the second gas stream vaporizes substantially all of the atomized liquid, and the resulting mixture of gas, vaporized liquid and residual droplets moves to the separation zone of the mixing/separation chamber. In the separation zone, the residual droplets gravitationally separate from the vaporized mixture, and the vaporized mixture free of a substantial amount of residual droplets is removed from the chamber.Type: GrantFiled: March 28, 2001Date of Patent: July 13, 2004Assignee: The BOC Group, Inc.Inventors: Michael D.

Patent number: 6761838Abstract: Partial oxidation of hydrocarbons to produce hydrogen and carbon monoxide is carried out by a cyclical process, which includes (a) contacting an oxygen ion conducting ceramic with air at a pressure between about 1 and 50 bara in a reactor, wherein oxygen from the air reacts with the ceramic, thereby producing an oxygen-enriched ceramic, and (b) contacting the hot, oxygen-enriched ceramic with hydrocarbon gas and optionally steam in the reactor. During the partial oxidation reaction phase of the process, the oxygen-enriched ceramic reacts with the hydrocarbon, thereby producing the desired gas products and regenerating the oxygen ion conducting ceramic for the next cycle of the process.Type: GrantFiled: July 20, 2001Date of Patent: July 13, 2004Assignee: The BOC Group, Inc.Inventors: Yongxian Zeng, Satish S.

Patent number: 6722161Abstract: A method for melting glass forming batch material includes charging the glass forming batch material to a glass melting apparatus; impinging a flame proximate to the surface of the batch materials to form a glass melt from the batch material; and bubbling the glass melt in proximity to the impinging flame with a fluid, advantageously producing a shearing action sufficient to enhance the solution rate of the glass forming batch material relative to the same system without bubbling, but without splashing glass and without significant production of seeds or blisters in the glass melt. Melting of the glass forming batch material with bubbling proceeds more quickly, and/or at lower temperatures than occurs in a comparable conventional glass melting furnace.Type: GrantFiled: April 15, 2002Date of Patent: April 20, 2004Assignee: The BOC Group, Inc.Inventor: John R.
