Abstract: A method for dynamically assigning a displayable realm name begins upon receipt of an authentication request to an application, such as a web application, being executed by an application server. In response, a determination is made whether an application realm name has been set in a configuration file associated with the application. If not, a custom display property is then evaluated. If the custom display property is set true, a realm name associated with an active authentication mechanism is retrieved and provided for display in an authentication panel. If the custom display property is set false, a default string is provided for display in the authentication panel. In this manner, an application server administrator can control what realm name is displayed to an end user in the event an application developer has not specified the realm name in the application configuration.

Abstract: Mechanisms are provided for performing security role definition testing. An application is received in a container of a runtime environment of the data processing system. The application has methods and security role definitions associated with the methods. A properties object, which specifies a user identifier to security role mapping, is received in the container. A test application is executed, in the container, by the processor, on an execution of the methods of the application based on the user identifier to security role mapping and the security role definitions. The test application tests an operation of the application with regard to the security role definitions. A result of the execution of the test application on the execution of the methods of the application is then output.

Abstract: A method, system and computer-usable medium are disclosed for managing identity authorizations to access information processing system resources. An application thread requiring access to target resources is initiated and associated with an authenticated client identity and a server identity. The resource authorization attribute of a resource required for execution of the application thread designates the use of a client identity, a server identity, or a client identity and server identity when attempting authorized access of the resource. The client identity, the server identity, or the client identity and server identity is then respectively used to access the target resource and the application thread is executed.

Abstract: A process for preparing isoflurane (1-chloro-2,2,2-trifluoroethyl difluoromethyl ether) by reacting PFE (2,2,2-trifluoroethyl difluoromethyl ether) with chlorine in the presence of ultraviolet light and added water, at a low temperature and/or at a high conversion.

Abstract: Apparatus suitable for annealing the interior walls of a nuclear reactor which comprises a nuclear reactor shell, a cap securely attached to the nuclear reactor shell, wherein the cap has an inlet line for the introduction of a hot gas under high pressure and an outlet line for removing low pressure gas from the interior of the apparatus, means, such as a cylindrical shell, that helps define an annular space adjacent to the vertical walls of the reactor through which gas can flow and means for directing low pressure gas to the outlet line.

Abstract: A process for improving resistance of pressure vessel shells, tubesheets, tubes, pipes, pipe fittings and machine parts to stress corrosion cracking comprising heating at least those portions of such bodies subject to danger by stress corrosion cracking to a critical elevated themperature level, cooling at least the surface portions of the metal body subject to stress corrosion cracking and then permitting such treated portions of the metal body to come to ambient temperature.

Abstract: A process for obtaining a gaseous sample from a stream containing solid particulate material, a gas, water and steam which comprises withdrawing a stream containing said particulate material, a gas, water and steam from a system containing the same through an elongated tubular member extending into said system and discharging said stream from said tubular member externally of said system, heating said stream in its passage through said tubular member, removing from said tubular member externally of said system a gaseous sample consisting essentially of said gas and said steam through a porous section of said elongated tubular member having openings in the wall thereof smaller in cross-section than the solid particulate material in said stream, and apparatus for carrying out the same.

Abstract: A process for improving resistance of control rod guide tube split pins in nuclear reactors to stress corrosion cracking comprising heating the split pin to a critical elevated temperature level, cooling at least the surface portions of the split subject to stress corrosion cracking and then permitting the split pin to come to ambient temperature.

Abstract: A process is claimed for removing the residual tensile welding stresses in the inner layer of the weld metal and the heat-affected zone of steel piping elements that have been butt-welded to each other end-to-end by means of a circumferential weld. The process involves mechanically introducing circumferential compressive stresses in the piping elements by applying a radial load inwardly on a section of at least one of the piping elements away from the weld such that the distance from the midplane of the section of the piping element upon which the radial load is applied to the weld midplane is equal to about two to about 12 times the thickness of the piping element upon which the radial load is applied. The distance from the edge of the section of the piping element upon which the radial load is applied that is adjacent the weld to the weld midplane is at least equal to about one-half the thickness of the piping element upon which the load is applied.

Abstract: A process for reducing the residual welding stresses in the weld metal, heat-affected zone and in the adjacent base metal of steel piping that have been butt welded to each other end to end by means of a circumferential weld which comprises mechanically introducing compressive stresses in said weld metal, heat-affected zone and adjacent base metal higher than their individual yield strengths but not exceeding their ultimate strengths in compression.

Abstract: A novel pipelock comprising a first pair of rings facing each other axially, with the inner diameter of each ring at the outer face being smaller than the inner diameter of each ring at the inner face, each of said first pair of rings comprising at least two circumferential parts, means to restrain longitudinal movement of facing circumferential parts outwardly from each other, at least one second ring comprised of at least two circumferential parts connected to each other, outwardly surrounding said first pair of rings, and constraining outward radial movement of said first pair of rings.

Abstract: An expansion joint for heat exchangers, reactors, steam boilers and the like to compensate for differential displacements. Differential axis expansion occurs when the pressure within the tubes or outside the tubes is raised or when a thermal expansion of the tubes and shells are different. The invention comprises a multi-layer flexible connection between the tube sheet to shell junction. The thin layers can bend parallel and accommodate large axial displacements between the shell and tubes without excessive stresses in the tube sheets. The fully penetrated but-weld of a central layer can be easily inspected by X-ray and provide the required seal between the shell and tube sheets. Other layers increase the strength of the joint.
