Title: Precision deep input guide clip for document scanners and document scanners incorporating same
Inventor: GATTO JEAN-MARIE
IPC: H04N1/12
Filed: 2000-06-27
Granted: 2004-07-27
Abstract: A document-guiding device that clips onto the image sensor of a document scanner ensures that documents to be scanned are introduced into the scanner at an optimal angle and are applied to the transparent surface of the image sensor at an optimal pressure, thereby avoiding scratching and soiling the sensor glass surface. Moreover, the deep input guide clip includes a sharp edge that acts as a scrapper to remove or flatten protruding impurities to further reduce soiling the sensor transparent surface. The deep input guide clip has the added benefit of stopping parasitic ambient light and protecting the image sensor against hard falling objects thus avoiding breakage of the transparent surface. The deep input guide clip forms a compact enclosure that may also hold a set of document proximity sensors and associated control electronics for precisely detecting the leading edge of the document when it is introduced in the scanner, its width and its trailing edge.

Patent CA-2327547-C (CA)
Title: Oligonucleotides containing pyrazolo[3,4-d]pyrimidines for hybridization and mismatch discrimination
Inventor: KUTYAVIN IGOR V
IPC: C12Q1/6827
Filed: 1999-04-05
Granted: 2009-10-27
Abstract: Oligonucleotides in which one or more purine residues are substituted by pyrazolo[3,4-d]pyrimidines exhibit improved hybridization properties. Oligonucleotides containing pyrazolo[3,4-d]pyrimidine base analogues have higher melting temperatures than unsubstituted oligonucleotides of identical sequence. Thus, in assays involving hybridization of an oligonucleotide probe to a target polynucleotide sequence, higher signals are obtained. In addition, mismatch discrimination is enhanced when pyrazolo[3,4-d]pyrimidine-containing oligonucleotides are used as hybridization probes, making them useful as probes and primers for hybridization, amplification and sequencing procedures, particularly those in which single- or multiple-nucleotide mismatch discrimination is required.

Granted: 2008-07-29
Abstract: L'invention concerne un procédé d'extraction de cuivre dans une extraction liquide-liquide par solvant, à partir d'une solution aqueuse comprenant une teneur élevée en sulfate, ce procédé consistant à élever la viscosité de la solution d'extraction et à disperser la solution aqueuse en gouttelettes, de manière à obtenir une agglomération dense des gouttelettes. On peut élever la viscosité de la solution d'extraction soit en augmentant, dans la solution d'extraction, la teneur de l'agent extractant utilisé, du réactif d'extraction, soit en utilisant un agent de dilution possédant une viscosité supérieure à celle de l'agent de dilution généralement utilisé. En élevant la viscosité de la solution d'extraction, on peut augmenter la durabilité du mélange de la dispersion d'extraction, ce qui contribue à faire diminuer la quantité de gouttelettes résiduelles. D'autres avantages résident en ce que l'écoulement de la solution d'extraction du procédé d'extraction décroît par rapport à l'écoulement de la solution aqueuse agissant en tant que source de cuivre, et en ce que la dimension du matériel d'extraction requis est réduite.

Abstract: A surgical spring clip includes two molded components, each having a jaw and a finger tab. The first component has a telescoping relationship with the second component and is moveable by operation of the finger tab between a first position wherein the jaws are generally open. A spring disposed between the tabs and the jaw biases the first and the second components toward the first position. The clip has a telescoping barrel with the general shape of a polygon in radial cross-section. An increased guidance link provides the clip with a guidance ratio of about 1.5 ratio. Alignment of the components is further enhanced by the provision of ramped projections and the accomodation of tolerances only along one side of the telescoping barrel. A simplified method of assembly requires movement of the second component through a window in the first component.

Abstract: The present invention relates generally to combustion engines, and more specifically, to an apparatus for controlling the power of combustion engines which have electrically-modulated throttle systems (also known as drive-by-wire throttle systems).  There are many applications in which it is desirable to modify the throttle control system of vehicles, for example, in limiting the power production of trucks operating in under ground mines. It is prohibitively expensive for vehicle manufacturers to supply such modified vehicles, so a system must be provided and installed as an after market product. The invention provides a simple and inexpensive solution in the form of a voltage modifying device which can be installed inline, between the accelerator pedal sensor and the engine control unit. The voltage modifying device can be designed to limit the power of the engine, or alter the performance profile in a desired manner.
