Patent CA-2288416-A1 (CA)
Title: Cut-off filters
Inventor: LI LI
IPC: G02B27/28
Filed: 1999-11-03
Abstract: A cut-off filter is based on the use of light at non-normal angles of incidence and on the use of coating materials with a large dispersion of the optical constants. The filter has a pair of optical media respectively defining an inlet port and an outlet port and having an inclined interface such that a light beam passing between the inlet and outlet ports strikes the interface at a non-normal angle of incidence. An active core is sandwiched between the optical media at the interface. In one embodiment, the active core has a refractive index which has high dispersion in the vicinity of the predetermined cut-off wavelength and an extinction coefficient which is high on the cut-off side and low on the transmission side. The angle of incidence .alpha. is selected such that total internal reflection occurs at the predetermined wavelength .lambda., to bring about a sharp cut-off in the transmittance of the filter at the predetermined wavelength.
Patent CA-2288562-A1 (CA)
Inventor: PROUGH J ROBERT
IPC: D21C7/06
Filed: 1999-11-04
Abstract: By establishing a relatively flat, for example, non-sharply conical, top profile of wood chips in a treatment vessel (such as a chip bin), the chips will be more uniformly steamed or otherwise treated (or have the treatment time of the chips extended) compared to if a conventional sharply conical top profile is established in the treatment vessel. The relatively flat top profile of the chips in the treatment vessel is established by utilizing a plurality (typically at least three, and preferably four or more) individually controlled gates (typically having a substantially polygon shape, such as triangular). The gates are mounted below the inlet of chips into a treatment vessel so to deflect, not significantly affect, or substantially preclude the flow of chips past them into the vessel depending upon the positions of each. An individual actuator is provided for each of the gates, such as a pneumatic piston and cylinder assembly, and the actuators are typically automatically controlled either by a controller including a timer, which opens and closes the gates in a predetermined established sequence and for a particular period of time (typically ranging between about one second-ten minutes), and/or utilizing a sensor for sensing the level of material in the treatment vessel (for example a plurality of sensors disposed around the treatment vessel for sensing the top profile of the pile of chips in the vessel).

Abstract: Provided are metal-air cells for connecting to one another to form a battery stack. Two or more of the cells are joined by heat or chemical fusing to create the battery stack. Each of the metal-air cells have a case with an exterior surface and an interior surface that defines a chamber that contains an anode and an air cathode. The case defines air openings that extend between the exterior surface and the interior surface for supplying air from the environment exterior to the case to the air cathodes within the chamber. In one embodiment, each metal-air cell includes a plurality of protruding connector members and a plurality of protruding mechanical stops. Two cells are joined by fusing connector members of one cell to connector members of the other cell. During the fusing of the connector members, the mechanical stops of the cells being joined abut one another to arrest movement of the cells toward one another. The arresting causes a plenum to be uniformly defined between the cells. The fused connector members and abutting mechanical stops cooperate to define a three-dimensional truss-like system that provides structural integrity. In an alternative embodiment, at least one of the two metal-air cells to be joined includes a plurality of connectors and is otherwise free of stops. These connectors can be aligned with and fused to similar connectors on the other cell or be fused directly to the exterior surface of the other cell. Connector members and mechanical stops are preferably integrally formed with their case and interspersed with the air openings.

Abstract: A neighborhood zone covering an enclosed or surrounded environment, such as a man-made building or high-rise, is defined (400) within a mobile telecommunications network by associating a plurality of base stations with respective cell areas. A same neighborhood list indicating all measurement channels being utilized within the neighborhood zone by said plurality of base stations is then further defined (400). The defined same neighborhood list is then transmitted (410) by each of the base stations within its respective coverage area. A  mobile station traveling within the neighborhood zone then scans and reports measurements (420) from the indicated measurement channels to the serving mobile telecommunications network. The mobile telecommunications network then effectuates a handover (460) in accordance with the received signal measurements. An idle mobile station further utilized the measurements to effectuate a cell re-selection.

Abstract: A system and method for performing the digital receive processing for multiple signals received over the same RF band is described. In a preferred embodiment of the invention, digital RF samples are stored in a queue which is accessed by a searcher (130) and demodulator (112). The searcher (130) and demodulator (112) are preferably located on the same integrated circuit along with the queue. The demodulator (112) demodulates a set of reverse link signals stored within the queue where each reverse link signal is received with at a particular time offset and processed using a particular channel code. The searcher (130) periodically searches for reverse link signals not being processed by the demodulator (112), and for access requests transmitted via the access channel. The searcher (130) preferably searches during the worthy power control groups of each reverse link signal, which corresponds to the two of sixteen power control groups transmitted during an eighth rate frame.

Title: Novel angiotensin receptor modulators and their uses
Inventor: THOMAS G ROGER
IPC: C07C215/00
Filed: 1999-06-07
Abstract: This invention relates to novel multibinding compounds that bind to angiotensin (AT) receptors and modulate their activity. The compounds of this invention comprise 2-10 AT receptor ligands covalently connected by a linker or linkers, wherein the ligands in their monovalent (i.e., unlinked) state bind to one or more types of AT receptors. The manner of linking the ligands together is such that the multibinding agents thus formed demonstrate an increased biologic and/or therapeutic effect as compared to the same number of unlinked ligands made available for binding to AT receptors. The invention also relates to methods of using such compounds and to methods of preparing them. The compounds of this invention are particularly useful for treating diseases and conditions of mammals that are mediated by AT receptors.  Accordingly, this invention also relates to pharmaceutical compositions comprising a pharmaceutically acceptable excipient and an effective amount of a compound of this invention.

Abstract: De nombreux gènes sont identifiés comme étant des gènes à régulation p-53, alors qu'ils n'étaient pas connus jusqu'à présent pour être régulés de cette manière. Il s'agit à la fois de gènes dont l'expression est induite et de gènes dont l'expression est inhibée par l'expression de p-53 de type sauvage. La surveillance de l'expression de ces gènes est utilisée pour fournir des indications de l'état de p-53 dans une cellule. Cette surveillance peut également être utilisée pour cribler des médicaments utiles contre le cancer, ainsi que des substances cancérogènes. Les anomalies de p-53 peuvent être compensées par apport de gènes induits par p-53 aux cellules. Elles peuvent également être compensées par apport de produits de recombinaison antisens à des gènes inhibés par p-53.
