Patent CA-2477565-A1 (CA)
Title: Extraction de composes contenant du soufre de flux d'hydrocarbures liquides
Inventor: KOCAL JOSEPH ANTHONY
IPC: C10G27/12
Filed: 2002-02-28
Abstract: L'invention porte sur un procédé efficace permettant d'extraire des composés de soufre organiques d'hydrocarbures liquides. Ce procédé porte plus particulièrement sur l'extraction de thiophène et de dérivés de thiophène d'un certain nombre de fractions de pétrole, y compris de l'essence, du diesel, et du kérosène. Au cours de la première étape du procédé, l'hydrocarbure liquide est soumis à des conditions d'oxydation afin d'oxyder au moins certains des composés de thiophène en sulfones. Puis, ces sulfones peuvent être décomposés par catalyse en hydrocarbures (par exemple de l'hydroxybiphényle) et en composés de soufre volatiles (par exemple du dioxyde de soufre). Ces produits de décomposition d'hydrocarbure demeurent dans le liquide traité en tant que composés de mélange utiles, alors que les composés de soufre volatiles peuvent être facilement séparés du liquide traité au moyen des techniques connues telles que la vaporisation ou la distillation instantanée.

Title: Method and system for processing tones to reduce false detection of fax and modem communications
Inventor: RESUTA DAVID P
IPC: H04Q1/30
Filed: 2003-04-29
Abstract: A tone processing method and communications which reduce the probability of falsely detecting modem and facsimile communications that occur on a communications link. The link connections a calling endpoint (105) to an answering endpoint (110). In a preferred embodiment, when the answering endpoint (110) goes off-hook in response to receiving a call from the calling endpoint (105), an elapse of time is measured while monitoring the link. If a predetermined amount of time elapses without detecting at least one tone on the link, tone detection criteria is modified to reduce tone detection sensitivity, or to ignore tones all together. In another embodiment, the tone detection criteria is similarly modified if voice activity is detected on the link. In yet another embodiment, when tones and voice activity occur at different times during a call, at least one characteristic is modified to optimize the link for the type of communications occurring on the link.

Title: Non-invasive substance concentration measurement using an optical bridge
Inventor: KUN STEVAN
IPC: G01N21/31
Filed: 2003-04-24
Abstract: An improved method for non-invasively measuring a concentration of a target analyte dissolved in a fluid flowing through a sample (80) is presented. It includes directing a probe beam (202) of electromagnetic radiation, consisting of time multiplexed components of different wavelengths (.lambda.P, .lambda.R), through the sample and measuring the difference of the absorption of the radiation at least one wavelength pair at different sample states.  During sample state changes, the amount of fluid containing the target analyte within the sample is changing, which varies the total amount of target analyte in the sample, as well as the absorption properties of the sample. The sample states are produced, for instance, by compressing (400) and uncompressing the tissue sample. The accuracy of the presented method is enhanced by including continuous estimation (94) of the amount of the fluid containing the target analyte within the sample, and measurement of the variations of the absorption at a wavelength at which the target analyte absorbs significantly. The method is particularly useful in measuring the concentration of a target analyte, such as glucose, in tissue containing blood. An apparatus for performing this method also is disclosed.

Inventor: ULCAR JOHN
IPC: C08J7/048
Filed: 2004-10-29
Abstract: A coating that can be adhered to a polyethylene gasoline container to substantially reduce its gas permeability, and a gasoline container treated with such a coating. A single-component cationic curing composition with increased impermeability to gasoline vapour uses a bis 'F' epoxy in combination with a catalyst and oxetane. The invention takes advantage of a narrower ultraviolet absorption spectrum of the bis 'F' epoxy, whereby ultraviolet radiation outside the UV absorption spectrum of the bis ',F' will activate the catalyst, the highly active superacid from the antimonate anion, without any significant reduction of the cationic curing reaction. In the preferred embodiment the bis 'F' and oxetane combination is used along with various additives included for flow and cosmetic purposes.

IPC: A21D13/00
Filed: 2005-02-09
Abstract: Toasted sandwich bread slices are provided having crusts that remain chewable and crunchy in texture even after the sandwiches are frozen and reheated. This improved crust texture is achieved by a process of physically tenderizing the crusts of toasted bread slices before they are frozen. The bread crusts are cracked by application of compressive force to the bread slices without permanently substantially flattening the bread slices. The cracked toasted bread are highly useful in constructing a sandwich that is frozen for stable storage, and later reheated for consumption without the crusts becoming overly hard, dry and difficult to chew.

Abstract: The present invention provides a lint pick-up device which includes an adhesive roll sleeve-engaging hollow support cylinder having an elongate handle portion extending outwardly thereof, and constructed and arranged to permit rotation of the support cylinder with respect to the handle portion. Suitable selected weight or weights are operatively associated with the hollow cylinder, thereby providing a weighted hollow cylinder. Such weight or weights fill or partially fill the interior of the hollow cylinder.  A closure plug is provided to make sealing closure engagement with the other end of the hollow support cylinder so as to cooperate therewith to define an enclosed weight-containing compartment. The mounting of the hollow cylinder to the handle may be directly by means of a sealed bearing to prevent the escape of material from the interior of the hollow cylinder. Alternatively, the mounting of the hollow cylinder to the handle may be indirectly through the intermediary of a compressible core onto which the hollow cylinder is slipped on and off An adhesive tape roll sleeve assembly is provided on the hollow cylinder. This invention thus provides a lint pick up device which can be used without the application of excessive force to the surface being cleaned.
