Patent CA-2235164-A1 (CA)
Inventor: GIOLANDO DEAN M
IPC: B01J27/125
Filed: 1997-07-15
Abstract: A method for producing organo metal chlorides directly from molten metal. The organo metal chlorides are formed by contacting an organo chloride directly with a metal melt. The preferred method includes the use of indium as the metal and methyl chloride as the organo chloride. The direct contact of the methyl chloride with the indium metal results in the production of dimethyl indium chloride or methyl indium dichloride depending on the contacting time and efficiency of the process. The resulting products are suitable for use as a precursor gas for chemical vapor deposition processes. Additionally, activator compounds such as oxides or halides are optionally added to the metal melt to enhance the reaction rate.

Title: Hierarchical error reporting system
Inventor: MCQUEEN STAN
IPC: G06F11/34
Filed: 1996-11-15
Abstract: Error reporting may be enhanced by utilizing a programming language, such as C++ and its attendant enhanced error reporting facility. The invention generates an error message at the function level where the error occurs, as well as noting the line of source code during which time the error occurred.  The resulting populated error message (82) is then rolled up toward the main program (20). At each preceding roll up level, an additional error message (90) is populated which notes the original error message (104) information as well as adding return path information. Thus, after completed roll up to the main program (20), stacked error messages (76) are made available to the user (10) that fully define the complete path involving the error (80), in addition to the identification of the source code line where the error occurred.
