Patent CA-2137376-A1 (CA)
Title: Methods and compositions for enhancing carbon fixation in plants
Inventor: NONOMURA ARTHUR M
IPC: C05G5/23
Filed: 1993-06-14
Abstract: 2137376 9400009 PCTABS00030 Plant growth stimulants containing compounds which increase intracellular carbon dioxide as the main active component and optionally supplemented with specific nutrients have been found to enhance productivity of plants. Exemplary compounds include lower alcohols, such as methanol, ethanol, propanol, and butanol, and amino acids, such as glycine, glutamate, and aspartate. Such growth stimulation appears to result, in part, from inhibition of stress-induced photorespiration according to a previously unrecognized photosynthetic pathway. Exposure of the plants to sunlight or other sufficient illumination following treatment with the compositions results in enhanced fixation of carbon dioxide and turgor.  Stimulant compositions may comprise from 5 % to 50 % by volume aqueous solutions of methanol or 0.1 % to 10 % by weight amino acids and are preferably applied by foliar spraying of plants and plant shoots.

Patent CA-2156417-A1 (CA)
Inventor: TINGLEY DANIEL A
IPC: D04H5/08
Filed: 1994-03-17
Abstract: A reinforcing panel (22) and process for making the same for use in reinforcing wood structural members uncluding laminated beams, wood I-beams, and trusses. The reinforcing panel is comprised of a plurality of synthetic fibers (24) that are arranged parallel to one another and aligned with the longitudinal direction of the panel, and accordingly the wood structure. The panel has substantially no transverse fibers. The fibers are maintained in position by a resin encasement (26) that completely encloses the fibers with the exception of some fibers that are closest to the surface. The surface of the reinforcing panel is treated so that those fibers (28) closest to the surface of the panel are caused to "hair up" so that the reinforcing panel may be used with nonepoxy adhesives which are commonly used in the laminated beam industry, such as resorcinal. The reinforcing panel of the present invention is fabricated by an improved pultrusion process which uses no mandrels, or woven mats and which provides for a selectable back pressure so that the fibers of the reinforcement panel are maintained in a state of tension during the resin cure, thereby: maintaining the parallel arrangement of the fibers, maintaining the longitudinal alignment of the fibers, and setting the initial strain of the fibers to decrease the initial deflection of a wood structure that is reinforced with the reinforcing panel of the present invention.

Patent CA-2162579-A1 (CA)
Title: False bar code inhibitor circuit
Inventor: BREMER EDWARD C
IPC: G06K7/10
Filed: 1994-05-09
Abstract: A false bar code inhibitor circuit includes a detector, a signal restore circuit, a comparator software controller, and a high impedance clamp circuit. Basically, the detector circuit detects the first transition from either high to low reflectivity or low to high reflectivity. The transition triggers the signal restore circuit which is set for a time constant which is longer than the longest possible time needed to encounter another transition during a valid bar code read. Each time a transition is encountered signal restore circuit is triggered. The externally adjustable comparator circuit compares the output from the signal restore circuit against a limit, which can be adjusted by the software controller. The output of the comparator drives a clamp which controls when the bar code digitizer can pass an output. With the software controller, the output of the comparator can be controlled allowing for control over the digitizer output. With the false bar code inhibitor a false bar generated at the start of a bar code scan can be masked. The inhibitor circuit also creates a "window" which is used to mask out valid bar code from a signal. Additionally, the inhibitor circuit allows for external control for adjusting threshold levels and for external control over the bar code digitizer output.

Title: A synthetic gene for d4 dopamine receptors
Inventor: HUFF RITA M
IPC: G01N33/566
Filed: 1994-06-01
Abstract: A modified gene coding for the human D4 dopamine receptor has been synthesized by chemo-enzymatic methods. The nucleotide sequence of the D4 dopamine receptor gene was changed to reduce the G+C content and to eliminate intronic sequences, while maintaining the published amino acid sequence. Using gene splicing by overlap extension and PCR amplification of long oligonucleotides (> 200 bases), 3 synthetic fragments of about 400 base pairs each were amplified, from which the full length gene was assembled.  Stable expression of this gene has been achieved in CHO-K1 cells, using an inducible expression system, and in HEK293 cells.

Abstract: A method of increasing retroreflective brightness in a retroreflective sheet material.   The retroreflective sheet material has a multitude of prism-like reflective elements imbedded in a transparent polymer plastic top film and glued by a grid of adhesive to a backing sheet.  The method includes the step of heating the retroflective sheet material until bubbles form in the transparent polymer plastic top film containing the prism-like reflective elements. The bubbles are confined  by  the  grid.    The  bubbles  serve  as  miniature magnifying lenses which increase retroreflective brightness and increase  the  exposure  area  thereby  providing  a  wider observation angle.
Patent CA-2165212-A1 (CA)
Inventor: COBURN DAVID CARL
IPC: G01R21/133
Filed: 1995-12-14
Abstract: An electrical metering system includes an electrical meter which is free of current sensors and an external current sensor for producing an output signal related to electrical current conducted by a transmission line to an electrical load associated with the electrical meter such that the power consumption of the electrical load can be computed by the electrical meter.  The current sensor generally can include an unbalanced bridge circuit for producing a scaled output signal related, according to a predetermined ratio to the electrical current conducted by the transmission line.  The electrical meter generally includes a register, responsive to the output signal produced by the external current sensor, to tabulate load data related to the power consumption of the associated electrical load.  By employing an external current sensor capable of providing relatively large current transformation ratios, the electrical meter need not include a current sensor and the design of the electrical metering system can be greatly simplified.
