Publication number: 20030138371Abstract: Gaseous mixture of chlorine dioxide and chlorine produced by reacting an inorganic acid with an aqueous solution of an alkali metal chlorate by controlled introduction of the inorganic acid into the aqueous solution of alkali metal chlorate. Inorganic acid passed through a volume of alkali metal chlorate flowing through a horizontal reactor in a plug flow regime results in an enhanced gaseous mixture of chlorine dioxide, chlorine and steam that can be withdrawn as a product stream.Type: ApplicationFiled: January 18, 2002Publication date: July 24, 2003Applicant: CDG Technology, Inc.Inventors: Thomas E. McWhorter, Aaron A. Rosenblatt, David Rosenblatt, Brazin Keramati

Patent number: 4414823Abstract: This invention is directed to an apparatus for freezing an article under cryogenic conditions which comprises a housing encompassing an entry port, a freezing station, an exit station and an exit port being at a greater vertical elevation than the entry port and freezing station. In connection with the housing, there are means provided for transporting the article to be frozen sequentially from the entry port, entry station, through the freezing station, and then to the exit station, preferably at a rate of travel which increases as the article is being transported through the exit station. A connection is made to the housing permitting the introduction of a cryogen into the freezing station thereby maintaining such station at a cryogenic temperature.Type: GrantFiled: January 21, 1982Date of Patent: November 15, 1983Assignee: Air Products and Chemicals, Inc.Inventor: Thomas E. McWhorter

Patent number: 4391128Abstract: A process is provided for making a distinction between solid, porous materials, e.g. thermoplastics, having surfaces which are either untreated or treated to render them measurably impermeable to volatiles. The surfaces are first exposed to a high concentration of a volatile fluid which is removed after a fixed time period. The surfaces are then exposed to an environment, e.g. a vacuum, to cause the volatile fluid to back-diffuse and the fluid that back-diffuses is measured. The rate at which the fluid back-diffuses from the untreated surface is considerably greater than that of the treated surface.Type: GrantFiled: April 20, 1981Date of Patent: July 5, 1983Assignee: Air Products and Chemicals, Inc.Inventor: Thomas E. McWhorter

Patent number: 4355488Abstract: A cryogenic deflashing apparatus is provided specifically adapted to remove residual flash from relatively large molded articles in a continuous high production deflashing operation. The apparatus incorporates a modular deflashing housing wherein entry, pre-freezing, blasting, and exit of multiple articles is accomplished simultaneously in discrete serially aligned operational compartments. A novel article conveyor transport mechanism is additionally provided which permits the transport speed of the articles through the various compartments to be independently varied during operation to maximize production efficiency.Type: GrantFiled: January 14, 1980Date of Patent: October 26, 1982Assignee: Air Products and Chemicals, Inc.Inventors: Robert E. Schmitz, David T. Stearns, Erwin Stegmann, Thomas E. McWhorter, Warren F. Geiger, Thomas J. Abrahamsen

Patent number: 4312156Abstract: This invention is directed to an apparatus for subjecting an article to shot blasting under cryogenic conditions which comprises a housing encompassing an entry station, an impacting station and an exit station. In connection with the housing, there are means provided for transporting an article to be shot blasted sequentially from the entry station, through the impacting station, and then to the station. A connection is made to the housing permitting the introduction of a cryogen into the impacting station thereby maintaining such station at a cryogenic temperature. The apparatus also has a means for directing media at a high velocity so as to impact upon an article to be treated while such article is being transported through the impacting station. The apparatus of the invention also functions to rotate the article while it is being transported through the impacting station, thereby permitting the stream of media to contact all critical portions of the article.Type: GrantFiled: March 17, 1980Date of Patent: January 26, 1982Assignee: Air Products and Chemicals, Inc.Inventor: Thomas E. McWhorter

Patent number: 4183384Abstract: A safety apparatus for use in fluid blending and dispensing devices wherein it is essential to insure that one of the fluids to be blended be maintained below a defined maximum concentration. The apparatus comprises a single valve located in the inlet line of the fluid to be controlled, which is operable upon detection of an increase in the flow rate of the fluid to be controlled or by a decrease in the flow rate of any of the other fluids with which it is being blended.Type: GrantFiled: January 18, 1978Date of Patent: January 15, 1980Assignee: Air Products and Chemicals, Inc.Inventors: Eugene D. Ervin, Frederick K. Kitson, David M. Krasiewich, Thomas E. McWhorter
