Abstract: An optical filter comprises a multi-mode waveguide (W2) and a single-mode waveguide (W1, W3) coupled in series, the interference of different modes at the multiple-mode/single-mode, interface being effective to filter an optical signal propagating through the waveguides to provide a desired wavelength response characteristic. The offset between the waveguides may be varied to control the filter characteristic. The filter may be formed in the cavity of a laser to produce an output having a comb-filter characteristic. It may be used as channel selector in WDM systems.

Title: Bcl-2-associated proteins
Inventor: REED JOHN C
IPC: C12Q1/02
Filed: 1994-11-09
Abstract: The present invention provides nucleotide sequences encoding proteins and fragments thereof that bind to Bcl-2-related proteins.  The invention also provides a Bcl-2-associated protein (BAP) such as the BAG-1, which is encoded by the Bcl-2-associated athanogene-1 and binds to Bcl-2. The invention also provides antibodies that specifically bind to a BAP.  The invention further provides methods for detecting agents such as drugs that alter the binding of a BAP such as BAG-1 or Raf-related protein with a Bcl-2-related protein and methods for detecting agents that induce dissociation of a bound complex formed by the association of a BAP and a Bcl-2-related protein. The invention further provides methods for modulating the activity of a Bcl-2-related protein in a cell by introducing into the cell a nucleic acid encoding a BAP or by introducing into the cell an antisense nucleotide sequence, which is complementary to a region of a gene encoding a BAP.
Patent CA-2176558-A1 (CA)
Inventor: CASE RONALD BURTON
IPC: C08G67/02
Filed: 1994-12-06
Abstract: Selon l'invention, on obtient des compositions adhésives améliorées à base de copolymère d'éthylène, pouvant être traitées en fusion, durcissables à l'humidité et présentant une aptitude à l'adhésion à la fois sur un substrat spécifique et sur une large gamme de substrats. Ces compositions sont des copolymères d'éthylène greffés contenant à la fois un groupe carbonyle dans la chaîne principale et un groupe alcoxysilane dans la greffe. Afin d'utiliser la composition en tant qu'adhésif servant à des températures élevées, il faut que le substrat contienne un catalyseur de condensation à base de silane, ou qu'il ait été préalablement traité à l'aide d'un tel catalyseur, ou que la composition adhésive elle-même contienne une faible quantité de ce catalyseur. Cette composition ainsi que le procédé l'utilisant sont particulièrement appropriés pour faire adhérer du PVC ou du polyester sur du bois ou du verre, et plus généralement pour faire adhérer entre eux une large gamme de substrats polymères.

Patent CA-2184982-A1 (CA)
Inventor: WHITEHOUSE CRAIG
IPC: G01N27/62
Filed: 1995-03-07
Abstract: Improvements have been made to the Electrospray and Atmospheric Pressure Chemical Ionization source chambers interfaced to mass spectrometers to simplify source performance optimization and source operation and to improve system sensitivity. The atmospheric pressure ion source procedure for optimizing performance has been simplified by adding windows along the sides of the atmospheric pressure ionization chamber allowing direct viewing of Electrospray and Atmospheric pressure ion source during operation. A cylindrical lens which extends along the side walls of atmospheric pressure chamber has been configured to be semitransparent for viewing into the chamber. This cylindrical shaped side lens is electrically isolated from the Electrospray liquid introduction needle and Electrospray chamber endplate. Improved Electrospray mass spectrometer system sensitivity can be achieved when operating the cylindrical lens with a higher potential difference between it and the Electrospray liquid introduction needle than is set between the needle and the endplate.

Abstract: L'invention porte sur un procédé de synthèse permettant d'obtenir un sesquioxyde de germanium carboxyéthyle pur en l'absence d'impuretés toxiques. Dans le cadre de ce procédé, ni le dioxyde de germanium ni le germanium métallique ne constituent des produits de départ. Le procédé comporte plusieurs étapes, soit: a) s'assurer de l'absence de tout tétrachlorure de germanium résiduel afin d'éviter qu'il ne contribue à la formation d'oxyde de germanium, b) éliminer tout dioxyde de germanium, c) faire disparaître toute trace de tétrachlorure de germanium qui aurait été produit, dans l'intervalle, par un quelconque dioxyde de germanium et, d) éliminer définitivement toute trace de dioxyde de germanium. Selon un autre procédé, on obtient un produit intermédiaire, de l'acide propionique trichlorogermane, (TPA), par la précipitation directe d'une solution concentrée au moyen d'un solvant halogéné, du dichlorométhane, de préférence, versé dans un solvant non polaire alkyle, de préférence de l'hexane, à la température ambiante, produit intermédiaire que l'on convertit ensuite en sesquioxyde de germanium carboxyéthyle.

Patent CA-2211841-A1 (CA)
Title: Overflow water screening apparatus
Inventor: FILION GILLES
IPC: E03F5/12
Filed: 1997-07-29
Abstract: The  water  screening  apparatus  of  the  invention includes a conduit in which is positioned a discharge pipe opening through which water flowing in the conduit is to be dispatched completely during normal water flow conditions.  The discharge pipe opening is positioned adjacent the conduit bottom wall portion so that as long as the water level does not rise above it, the water is completely dispatched therethrough.  A bar screen is transversely disposed inside the water conduit and downwardly slopes from the conduit upstream end to the discharge pipe opening and covers the whole conduit width.  When the water level rises above the discharge pipe opening, the water flowing above the discharge pipe opening will flow through the bar screen, the latter intercepting any macroparticles beyond a set threshold level carried by the water flow.  These intercepted solid particles will  slide along the bar screen under the pressure exerted by the water flow, to be carried in this way into the refuse discharge pipe to be disposed of along with part of the water flow.  This way, during water overflow conditions, even if the water is not completely disposed of by means of the discharge pipe opening, the overflow water will not carry large solids or suspended matter, since it will be screened before being conveyed elsewhere, for example to a river.

Patent CA-2224299-A1 (CA)
Inventor: TENSOR PAUL M
IPC: F16J15/12
Filed: 1997-12-10
Abstract: A composite gasket including facing material and a core material. The core material includes tanged portions which are formed by disturbing a surface of the core. The tang portions preferably terminate into pointed tips which penetrate the facing material when it is forced against the tangs. When sufficient force is applied against the facing material, the pointed tips of the tangs deform inwardly forming hook shaped ends. These hook shaped ends help form and maintain an excellent mechanical bond between the core material and the facing material. The forming of the tangs does not penetrate completely through the thickness of the core material but simply forms a slight divot in the surface of the core material. Thus, there is no possibility of leakage through the core material.
