Abstract: An interlocking assembly includes a frame, a first arm coupled to the frame, and a second arm coupled to the frame. The first arm and/or the second arm is moveable between an open position and a closed position, such that the first and second arms overlap to define a first area when the first and second arms are in the closed position.

Abstract: A redundant clock module provides a highly reliable fixed clock reference output. This clock reference output is based on at least two internal reference oscillators that are monitored and eliminated from use if they are not operating or within tolerance requirements. The redundant clock module comprises at least two oscillators, detection circuitry, switching circuitry and control circuitry. If a primary oscillator fails or is out of tolerance, the redundant clock module will detect the failure or out of tolerance condition and switch to a secondary working and in tolerance oscillator to take over primary timing functions of an end user application. The redundant clock module provides a slow and seamless transition between oscillator switching to assure no significant phase shift or runt pulses will affect the end user application.

Abstract: A method for performing pixel addressing operations for a tiled image. The method maintains separate X and Y components of a pixel address in a tiled image. Each component includes a tile and pixel index spaced apart by blank bit fields such that when combined, the X and Y components form a pixel address that is directly dereferenced to read or write a pixel in the tiled image. To decrement or increment the X or Y component, the method introduces a mask such that any carry bit can be moved across the blank bit field between the tile and pixel indices. This enables the method to use the same efficient add/subtract and mask operations whether or not a pattern of pixel accesses crosses a tile boundary. The X and Y components are represented as virtual X and Y coordinates in a two-dimensional array of pixels to hide the details of the add/subtract and mask operations from the programmer.

Abstract: A support for a cylindrical container adapted to engage said container at its mid-section and containing a rapid connect and disconnect flexible member adapted to pull together two hinged semi-circular members to permit the container to be firmly held in position.

Abstract: A method for a computer compiler for an object-oriented programming language for implementing virtual functions and virtual base classes is provided. In preferred embodiments of the present invention, the data structure layout of an object includes a virtual function table pointer, a virtual base table pointer, occurrences of each non-virtual base class, the data members of the class, and occurrences of each virtual base class. If a class introduces a virtual function member and the class has a non-virtual base class with a virtual function table pointer, then the class shares the virtual function table pointer of the non-virtual base class that is first visited in a depth-first, left-to-right traversal of the inheritance tree. In preferred embodiments of the present invention, each instance of a given class shares a set of virtual function tables and virtual base tables for that class.

Abstract: A system and method of incrementally coupling a high level language into an object file is disclosed. A source file and an object file are organized into logical blocks. An intermediate file, termed an .mdt file, is generated and stores information about the logical blocks in both the source file and the object file and their relationship to each other. Boundaries are established in the source program to define logical blocks within it, each block being termed a function. Each function is further divided into a global region and a local region. If a change has been made in a particular local region in the source file, only that region is recompiled. The recompiled portion of the .obj file is patched into the .obj file to replace the previous material corresponding to that region. Significant time savings is realized by incrementally compiling the source program because only those local regions which have been changed are recompiled and they are patched into the existing .obj file.

Abstract: A method and system for recording debug commands as they are executed on a program is disclosed. The line number in the program reached after executing the debug command is also stored on the tape. The debug history tape is a sequential record of the debug commands. A user may reexecute one or more of the debug commands on the program by running the debug history tape. The user may stop the reexecution of the debug commands on a given line in the program generally in the area thought to contain the error, by moving an ending pointer to that region in the debug history tape. The tape will execute up to the ending pointer and then stop. The user may then examine the program, execute additional debug commands or take other action to locate the error. Any additional debug commands are also stored on the tape. The ability to reexecute the debug commands and stopping their execution at selected lines in the program aids the user in locating errors. After locating the errors, the user modifies the program.

Abstract: The disclosure is of the extraction by ion exchange and use, especially in edible materials, of functional protein material having one or more useful surface-active properties such as foaming, foam stabilization, gelation, or water-or fat-binding characteristics.

Abstract: An ion exchange process is characterized by the use of an ion exchange cellulose made by reacting unregenerated cellulose with a monomeric substance having at least one ionizable chemical group which imparts ion exchange properties to the cellulose reaction product, and thereafter regenerating the activated cellulose reaction product to yield an activated regenerated cellulose having ion exchange properties.

Abstract: Cellulosic ion-exchange materials, 0-10% cross-linked, are used to extract dissolved materials (especially those giving large ionic species) from liquid media by ion-exchange interaction conducted under agitated conditions produced by an agitator located in the reaction zone or by certain turbulence-inducing arrangements. The cellulosic material can be recirculated to treat further liquid, and the process is particularly suited to continuous operation.
