Title: N-port reconfigurable dwdm multiplexer and demultiplexer
Inventor: KECK DONALD B
IPC: G02B6/293
Filed: 1999-01-07
Abstract: An N-port optical wavelength division multiplexer (10) and demultiplexer includes two evanescent wave couplers (30, 70) connected by N optical paths (110, 112, 114, 116, 11N). Each of the optical paths includes wavelength-selecting elements (50, 52, 54, 56) that are used to select specific wavelengths of light. Light signals composed of N wavelengths of light introduced to an exterior port in one of the couplers are split substantially equally among all the optical paths within the coupler, so that each optical path exiting the coupler includes light of all the wavelengths initially introduced to the coupler. The wavelength selecting elements disposed on each optical path are situated to direct the light in a manner such that light of only the selected wavelengths interferes constructively at a given exterior coupler port and other wavelengths interfere destructively.

Title: Method of treating spent potliner material from aluminum reduction cells
Inventor: BARNETT ROBERT J
IPC: C01F7/50
Filed: 1997-12-11
Abstract: A process for treating spent potliner material from aluminum reduction cells and recovering useful products. In the process, spent potliner material is introduced into an acid digester containing, for example, sulfuric acid.     A gas component is produced which includes hydrogen fluoride and hydrogen cyanide. A slurry component is produced which includes carbon, silica, alumina, sodium compounds such as sodium sulfate, aluminum compounds such as aluminum sulfate, iron compounds such as iron sulfate, magnesium and calcium compounds such as magnesium and calcium sulfate. The slurry component remains in the digester after the gas component is removed. The gas component is recovered and heated an effective amount to convert or decompose the hydrogen cyanide to a remaining gas component including CO2, H2O, and nitrogen oxides, as well as HF gas. The remaining gas component is directed through a water scrubber in which the HF gas is converted to liquid hydrofluoric acid. The hydrofluoric acid is then admixed with alumina trihydrate to form aluminum fluoride and water. Valuable refractory materials and salts are recovered also.

Patent CA-2325331-A1 (CA)
Inventor: EMLER CAROL A
IPC: C12N15/09
Filed: 1999-03-26
Abstract: A transformation protocol is described for the particle mediated transformation of soybean. This protocol is based on gene delivery into the growing meristem of a soybean embryo. Prior transformation protocols based on meristematic gene delivery in soybean did not depend on selection due to difficulties in using selection agents in differentiated tissue in soybean. It has been found that a post bombardment culture with glyphosate selection can dramatically increase the efficiency of such a transformation protocol.

Title: Method and apparatus for data compression of network packets employing per-packet hash tables
Inventor: DORWARD SEAN MATTHEW
IPC: H03M7/40
Filed: 2001-02-07
Abstract: A method and apparatus for compressing packets that enables inter-packet compression thereby achieving greater robustness and increased compression ratios. More particularly, a variable-length coding is used in conjunction with maintaining a separate hash table for each packet. Further, the per-packet hash table indexes particular byte strings in the packet but does not index data in any other packet(s).  That is, a respective separate hash table for each packet is employed wherein such hash table is constructed as the particular packet is compressed. As such, the respective hash table is encoded with the particular packet. Employing a per-packet hash table in combination with variable history state inter-packet compression provides for efficient and robust overall compression of the packets.

Inventor: MAROCCO GREGORY M
IPC: F01N13/04
Filed: 1999-08-13
Abstract: A catalytic converter and resonator combination (10) is contained within a common canister (12). The catalytic converter component (24) is positioned upstream of the resonator component (34) (relative to engine exhaust flow) for receiving additional heat from the engine exhaust entering the device.  Preferably, the substrate element (28) of the catalytic converter component (24) is formed of a strong and heat resistant ceramic material, such as Dow-Corning XT (tm) or other suitable ceramic material. The use of such strong and heat resistant material allows the substrate walls to be relatively thin, thus providing a high surface area to substrate volume ratio. The passages between the substrate walls are also relatively large, thus reducing internal resistance for increased flow therethrough.
