Publication number: 20030158916Abstract: A computer network server using HTTP (Web) server software combined with foreground view composer software, background view composer software, a view tile cache, view tile cache garbage collector software, and image files provides image view data to client workstations using graphical Web browsers to display the view of an image from the server. Problems with specialized client workstation image view software are eliminated by using the Internet and industry standards-based graphical Web browsers for the client software. Network and system performance problems that previously existed when accessing large image files from a network file server are eliminated by tiling the image view so that computation and transmission of the view data can be done in an incremental fashion. The view tiles are cached on the client workstation to further reduce network traffic. View tiles are cached on the server to reduce the amount of view tile computation and to increase responsiveness of the image view server.Type: ApplicationFiled: January 17, 2003Publication date: August 21, 2003Applicant: Digital Paper CorporationInventors: John C. Cronin, Cecil V. Hornbaker

Patent number: 4300028Abstract: A rotary selector switch comprises a generally flat blade mounted for rotation in its own plane about an axis passing through it into and out of contact with one or more of several spaced terminal contacts.Type: GrantFiled: September 25, 1979Date of Patent: November 10, 1981Assignee: Gould Inc.Inventors: John C. Cronin, Walter M. Wilson

Patent number: 4202998Abstract: An internal shield ring for the air entrance bushing of a gas-insulated bus system tapers inwardly at its free end and has a reduced spacing with respect to the central bushing conductor to increase the dielectric stress between the end of the shield ring and the central bus. This reduces the stress on the external bushing insulation material and thus permits a reduction in the bushing diameter.Type: GrantFiled: July 17, 1978Date of Patent: May 13, 1980Assignee: Gould Inc.Inventor: John C. Cronin

Patent number: 4132855Abstract: A support insulator for supporting a high-voltage conductor within the interior of a gas-filled grounded housing has a generally triangular configuration, with the central bus supported within the interior of the triangle and with the apices of the triangle engaging the inner diameter of the grounded enclosure. An inner hub extending from the legs of the triangle assists in the support of the central insulator. The combination of a gas-filled high-voltage transmission line with a plurality of support insulators extending along the length of the line is disclosed.Type: GrantFiled: February 14, 1977Date of Patent: January 2, 1979Assignee: Gould Inc.Inventors: Robert M. Clark, John C. Cronin, David H. Reighter, Vasu H. Tahiliani

Patent number: 4130850Abstract: A high speed fault diverter switch is connected near the input side of a gas-insulated substation. The switch is normally open and is used in response to arcing anywhere within the substation to connect the gas-insulated high-voltage conductor to ground for each phase of the system at high speed to divert the fault current to ground.Type: GrantFiled: January 12, 1977Date of Patent: December 19, 1978Assignee: Gould Inc.Inventors: John C. Cronin, Willy Schuetz

Patent number: 4034147Abstract: A contamination control device for use in a gas-insulated transmission bus consisting of a cylindrical center conductor coaxially mounted within a grounded cylindrical enclosure. The contamination control device is electrically connected to the interior surface of the grounded outer shell and positioned along an axial line at the lowest vertical position thereon. The contamination control device comprises an elongated metallic member having a generally curved cross-section in a first plane perpendicular to the axis of the bus and having an arcuate cross-section in a second plane lying along the axis of the bus. Each opposed end of the metallic member and its opposing sides are tapered to form a pair of generally converging and downward sloping surfaces to trap randomly moving conductive particles in the relatively field-free region between the metallic member and the interior surface of the grounded outer shell.Type: GrantFiled: February 25, 1976Date of Patent: July 5, 1977Assignee: Gould Inc.Inventors: Robert M. Clark, John C. Cronin
