Abstract: A container for storing compressed gas includes a plurality of aligned glass capillaries extending into a tubesheet. Each of the capillaries has an open end flush with a front face of the tubesheet. An end cap having a gas outlet connectable to a compressed gas valve or conduit is fitted to the tubesheet in gas-tight fashion to form a high pressure space defined by inner surfaces of the capillaries, the front face of the tubesheet, and inner surfaces of the end cap.

Abstract: A method of integrating an Xt Intrinsics based toolkit with a JAVA application. The application includes a process thread that implements an X event loop and an application thread that suspends execution of the event loop to allow a call to be made through the JAVA Native Interface to a toolkit or a widget to cause something to be displayed. The application thread includes a write socket to communicate a token to a read socket of the event loop, and performs a blocking read suspending the thread. The event loop returns an acknowledgment token via a write socket to a read socket of the thread that unblocks its blocking read and the event loop invokes its own blocking read suspending its execution. The file descriptor function, XtAppAddInput, preferably, is used to read the token and to set the blocking read. After a toolkit call is made, a token is sent from a second write socket of the thread to a second read socket of the event loop that unblocks its blocking read resuming the event loop.

Abstract: A workstation includes a regression testing program which tests application programs developed on the workstation using stored test scripts. A test directory tree is maintained to mirror a source code directory tree, and the test directory tree is employed to select the test scripts to be used in testing any newly compiled application programs.

Abstract: A graphic workstation receives digitized medical images and the user creates textual information that is to be displayed on the images. The text along with associated properties are packaged as a data structure along with a set of properties, and the data structure is passed through a pipeline having a series of formatters. The formatters are easily configured by the user to modify the properties of the text data structures as they flow through the pipeline prior to being rendered on a display.
