Patent number: 7536307Abstract: An automated method and system for facilitating timely use and/or redemption of the unused portion of an electronic ticket are provided. In accordance with the method, ticket data (e.g., from an electronic ticket) is collected from a financial transaction account, then a search engine uses said ticket data to find open tickets. Finding open tickets includes setting an aging period and adding it to the scheduled departure date of the issued ticket, and a reminder period is set and subtracted from the scheduled date of a ticket. If the scheduled departure date plus the aging date is earlier than the current date, a determination is made as to whether the ticket has been used. If the scheduled date minus the reminder period is earlier than the current date, then a message is communicated to the traveler reminding him to use or redeem the ticket.Type: GrantFiled: February 10, 2004Date of Patent: May 19, 2009Assignee: American Express Travel Related Services Company, Inc.Inventors: Robert G. Barnes, Diego Espinosa, Meg Rediess, Lisa Steury

Patent number: 5919362Abstract: An encapsulated filter cartridge assembly is disclosed which is adapted and configured for reception within an elongated cartridge housing of a filtration system. The filter cartridge assembly includes an elongated filtration element, a connector head positioned adjacent an upper end portion of the filtration element, an outer shell extending axially from the connector head and encapsulating the filtration element, and an expansion joint integrally formed in the outer shell to facilitate expansion of the outer shell within the elongated cartridge housing.Type: GrantFiled: April 28, 1997Date of Patent: July 6, 1999Assignee: Cuno, Inc.Inventors: Robert G. Barnes, William Contaxis, III, Bruce G. Taylor

Patent number: 5399264Abstract: A compressible differential pressure energized seal (18) coacting between a filter element (10) and the like and a housing (21) comprises a compressible portion (35) having a large open end (36) and a small open end (37), the large end (36) directed toward and contacting the housing (21 ) and the small end (37) directed toward the filter (10) element; and an annular flange (38) integrally attached to the compressible portion (35) at its small end (37) and extending outwardly, the flange (38) operatively communicating with the filter element (10). The seal (18) may also include at least one flap (43) to center the filter element (10) to which it is attached onto a centering rod (31 ) carried within the housing (21 ). Such a seal (18) is compressed when the element (10) is operationally enclosed within the housing (21 ) to provide a leak-proof seal during operation and is self-energizing during operation such that as the differential pressure increases, it more forcefully engages the sealing surface.Type: GrantFiled: March 22, 1993Date of Patent: March 21, 1995Assignee: Cuno, IncorporatedInventors: John L. Pulek, Robert G. Barnes, Eugene A. Ostreicher

Patent number: 4783262Abstract: The present invention sets forth an improved cell type filter cartridge in which the individual cells contain a separator disc having stiffening members formed at the central aperture of the cell and connected to a plurality of the separating ribs in spaced relation to each other. The coaction of the two or more discs with the separator ribs provides for a rigid, box-like structure of the ribs to impart a substantial cantilevered strength to the ribs. Additionally, at least one of the stiffening discs is positioned at or near the ends of the separator ribs to act as a load-bearing surface to prevent media intrusion of the filtering medium and thereby maintain the area of the flow path of the filtered liquid as it passes through the central aperture of the disc.Type: GrantFiled: March 30, 1987Date of Patent: November 8, 1988Assignee: Cuno IncorporatedInventors: Eugene A. Ostreicher, Arto Artinyan, Robert G. Barnes

Patent number: 4743418Abstract: A cationic charge modified microporous membrane is provided. The membrane comprises a hydrophilic organic polymeric microporous membrane having bonded thereto, through a cross-linking agent, a charge modifying amount of a cationic charge modifying agent. The charge modifying agent is an aliphatic amine or polyamine, preferably tetraethylene pentamine, and the cross-linking agent is an aliphatic polyepoxide having a molecular weight of less than about 500, preferably 1, 4 butanediol diglycidyl ether. The microporous membrane is preferably nylon. The process for applying the charge modifying agent to the membrane, preferably comprises contacting the membrane with an aqueous solution of the charge modifying agent and then contacting the membrane with a substantially aqueous solution of the cross-linking agent. The preferred process uses high purity water, i.e.Type: GrantFiled: August 17, 1984Date of Patent: May 10, 1988Assignee: Cuno IncorporatedInventors: Robert G. Barnes, Jr., Chaokang Chu, George T.

Patent number: 4735892Abstract: A photosensitive element suitable for manufacture of an external nameplate comprises a substrate carrying a cured non-etchable background surface, an etchable curable polymeric layer that can be etched imagewise to provide an image viewable against a background, and a photosensitive layer. A nameplate or other sign is obtained by imagewise photoexposure of the photosensitive layer, developing the image to reveal the curable layer, etching the revealed curable layer imagewise, removing the residual photosensitive material and then baking the product.Type: GrantFiled: May 22, 1986Date of Patent: April 5, 1988Assignee: Davies Brothers Ltd.Inventors: Kenneth W.

Patent number: 4645602Abstract: A process for producing an integral single layer polymeric microporous filter membrane within which a reinforcing web is embedded. The process comprises passing a reinforcing web through a first reservoir of casting solution of polymer and then simultaneously calendering both sides of the coated web to provide for penetration of the solution into the web and to remove substantially all entrapped air from the web. The calendered reinforcing web is then passed through a second reservoir of casting solution and then through a quenching bath to form micropores throughout the coatings.Type: GrantFiled: September 17, 1984Date of Patent: February 24, 1987Inventors: Robert G.
