Title: Electrochemical deposition of a composite polymer-metal oxide
Inventor: MCNALLAN MICHAEL
IPC: C25D11/06
Filed: 1998-08-26
Abstract: A process for forming polymer films through electrochemical techniques utilizing electrolytes with include conductive polymer. The resulting polymer films are electrically conductive and corrosion and wear resistant. Polyamino-benzene (polyaniline), for example, undergoes an insulator-to-metal transition upon doping with protonic acids in an acid/base-type reaction. Composite polymer-aluminum oxide films may be formed by modifying the anodizing electrolyte, resulting in the codeposition of polyaniline during aluminum anodization. A nonprotonated, ring-sulfonated aluminun salt of polyaniline was determined to be the reaction product within the aluminum oxide phase of the codeposited films. A second process, which incorporates electrochemical sealing of the anodic layer with polyaniline, was also developed. The formation of these composite films is documented through experimental processing, and characterized through scientific analysis and engineering tests. Scientific characterization determined the codeposition process yields chemically and metallurgically bound composite films. Engineering testing determined the films, obtained through a single step, exhibit superior wear and comparable corrosion resistance to conventionally anodized and sealed films processed through two steps, demonstrating the increased manufacturing efficiency that can be realized using the processes of the present invention.

Title: Oligonucleotides for amplification and detection of hemochromatosis genes
Inventor: GARIC-STANKOVIC ANA
IPC: C12Q1/68
Filed: 2000-04-14
Abstract: The present invention provides oligonucleotides and methods for amplifying, detecting and identifying sequence variations associated with hemochromatosis. It has been found that the reduced efficiency of primer extension by DNA polymerases when the 3' end of a primer does not hybridize perfectly with the target can be adapted for use as a means for distinguishing or identifying the nucleotide in the target which is at the site where the diagnostic mismatch between the detector primer and the target occurs. The efficiency of detector primer extension is detected as an indication of the presence and/or identity of the sequence variation in the target. The inventive methods make use of hemochromatosis gene (HFE)-specific amplification primers and nucleotide mismatches at or near the 3' end of a detector primer to amplify the HFE gene and discriminate between wild-type alleles and single nucleotide polymorphisms which may occur in exon 2 and exon 4 of the (HFE) gene.
Patent CA-2307926-A1 (CA)
Inventor: DEGELMAN WILFRED J
IPC: B62D49/06
Filed: 2000-05-09
Abstract: A high clearance farm vehicle, such as a tractor, is capable of accepting different front attachments to enable it to operate as either a swather or a sprayer. The front and rear sections of the vehicle's chassis are connected by an articulating oscillating joint which permits the vehicle's rear wheels to follow the path of the front wheels while turning thereby reducing damage to crops. The oscillating nature of the joint improves traction by allowing the wheels to always have full contact with the ground. A rear mounted engine counterbalances the weight of a front mounted attachment such as a swather head. The mounting of the cab on the front section of the vehicle away from the engine reduces noise experienced by the operator and permits the operator to have a direct line of sight to the operation of the vehicle. The use of active suspension and chemical application rates permit the vehicle to be transported and operated at higher speeds.

Abstract: This invention relates to derivatives of the conopeptide MII, an .alpha.-4/7 conotoxin peptide, in which amino acid residues are substituted as described herein while maintaining the basic activity of MII. The present invention also relates to the discovery of the 3-dimensional structure of MII, and the relationship of its structure to its specificity to the .alpha.3.beta.2 subtype of the neuronal nicotinic acetylcholine receptor (nAChR). The present invention also relates to computer based programs for the expression of the three-dimensional structure of MII and peptide analogs, peptide mimetics or non-peptide mimetics thereof. The structural characteristics may be correlated with biological activity to enable the design of .alpha.-4/7 conotoxin peptide analogs and peptide mimetics which demonstrate the same specificity to neuronal nAChR. Such analogs and peptide mimetics are useful as cardiovascular agents and for treating or detecting small-cell lung carcinoma (SCLC).

Title: Binary adder
Inventor: BLOW KEITH JAMES
IPC: G06E1/04
Filed: 1998-12-08
Abstract: The present invention relates to apparatus for determining the sum of first and second optical binary words. The apparatus uses a first optical logic gate (35) and a second optical logic gate (17) to generate respective first and second combination words which represent a logical combination of the binary words applied to the respective logic gates (17, 35).

Title: Apparatus and method of preventing sudden acceleration of vehicle
Inventor: LEE SOO SUNG
IPC: B60W10/184
Filed: 2000-09-20
Abstract: Apparatus and method for preventing sudden acceleration of a vehicle having an automatic transmission by detecting the sudden acceleration with use of transmission state information and rpm.      A controller determines that sudden acceleration occurs if the rpm abruptly increases within a first reference time in state that the transmission maintains a stop state, output voltage of an accelerator pedal detected by an ACC detecting unit is less than a predetermined level after inputting a start key. In addition, the controller determines the sudden acceleration if the transmission changes to a driving state and the rpm abruptly increases within a second reference time. When the vehicle drives at a high speed, the controller detects sudden acceleration only when the transmission changes by repeatedly counting the rpm. The controller may also be a central processor unit in an engine control unit of the vehicle.      Such apparatus and method may brake the vehicle in case of sudden acceleration, so prevent accident caused by the sudden acceleration.

Title: Monitoring fluid condition with a spiral electrode configuration
Inventor: HIRTHE RICHARD W
IPC: G01N27/02
Filed: 2000-10-30
Abstract: A plug for insertion through the wall of a vessel filled with fluid to be monitored has an extension immersed in the fluid which has a pair of wire electrodes helically wound thereon in spaced arrangement. The electrodes are wound at a uniform pitch in one embodiment and wound with regions of closely and widely spaced pitches in another embodiment. In a third embodiment, the electrodes are helically wound in spaced parallel arrangement at a pitch greater than the spacing of the pair. A thermistor is disposed on the extension for providing a fluid temperature signal. The electrodes are excited sequentially by a low voltage at a fractional Hertzian (low) frequency and a Hertzian (high) frequency and the current and temperature are measured. The impedance and differential impedance are computed from the measured currents. From stored values of the differential impedance as a function of temperature for various known fluid conditions, the condition of the fluid is determined; and, if greater than a predetermined threshold, an alarm is activated and/or the fluid condition displayed.
