Patent CA-2224751-A1 (CA)
Title: Self-actuating hot air register deflector and cover
Inventor: CHAMPAGNE DOUGLAS K
IPC: F24F11/76
Filed: 1998-03-09
Abstract: This invention relates to the automatic opening and closing of typical forced hot air registers deflector and cover. The usual and common practice of deflecting hot air as it leaves the register is to place a separate deflector on the register. These deflectors are meant to direct the hot air to the center of the room where it is most desired. The current available deflectors do not act as a cover and are inconvenient as they protrude above the floor and are therefore in a position to be easily displaced and broken. It is the purpose of this invention to prevent this occurrence by automatically closing the deflector almost flat with the floor and at the same time acting as a cover for the register preventing such things as dust, dirt, spilled liquids, dropped objects, insects, etc. from entering the hot air system. The heat from the hot air system causes the bimetallic spring to move, (either expand or contract), causing the actuating rod to push up the register deflector/cover.  The bimetallic spring holds the deflector/cover in the fully opened position until the heat shuts down thereby causing the spring to rotate in the opposite direction and lowering the deflector/cover to the fully closed position.

Title: Targeted cytotoxic anthracycline analogs
Inventor: NAGY ATTILA A
IPC: A61K47/48
Filed: 1996-11-14
Abstract: This invention is in the field of the chemistry of targeting anticancer anthracycline derivatives.     More particularly, it concerns doxorubicin (DOX) or its daunosamine modified derivatives (DM-DOX) linked covalently to analogs of peptide hormones such as LH-RH, bombesin and somatostatin. These covalent conjugates are targeted to various tumors bearing receptors for the peptide hormone analogs.     The compounds of this invention are represented by the General Formula: Q14-O-R-P wherein Q has general formula (II) wherein:  Q14 signifies a Q moiety with a side chain at the 14 position; R- is H or -C(O)-(CH2)n-C(O)- and n = 0-7; R' is NH2 or an aromatic, saturated or partially saturated 5- or 6-membered heterocyclic compound having at least one ring nitrogen and optionally having a butadiene moiety bonded to adjacent carbon atoms of said ring to form a bicyclic system; P is H or a peptide moiety, suitably an LHRH, somatostatin or bombesin analogs. Nevertheless where R' is NH2, then R and P are other than H. When R and P are H, then R' is other than NH2. A novel synthetic reaction has been discovered in the course of this work to form partially saturated heterocyclic moieties from vicinal and disjunct i.e., .alpha.,.beta.- or .alpha.,.gamma.-hydroxy primary amines. Q6 is DOX; Q2 is 3'-deamino-3'-(pyrrolidine-1"-yl)-doxorubicin (AN  181); Q3 is 3'-deamino-3'-(isoindoline-1"-yl)-doxorubicin (AN 184); Q4 is 3'-deamino-3'-(3"-pyrroline-1"-yl)-doxorubicin (AN 185); Q5 is 3'-deamino-3'-(3"-pyrrolidone-1"-yl)-doxorubicin (AN 191); Q6 is 3'-deamino-3'-(2''-pyrroline-1"-yl)-doxorubicin (AN 201); Q7 is 3'-deamino-3'-(3"-piperidone-1"-yl)-doxorubicin (AN 195); Q8 is 3'-deamino-3'-(1",3"-tetrahydropyridine-1"-yl)-doxorubicin (AN 205).

Title: Method and apparatus for improved control over cellular systems
Inventor: REUDINK MARK
IPC: H04W24/00
Filed: 1996-12-31
Abstract: System and apparatus for actively managing calls in a wireless cellular network. A host receives input data from a plurality of cells regarding the status of calls in that cell. Input data may include call variables such as carrier signal strength over interference (C/I), forward and reverse link power, beam and channel assignments, handoff status, and triangulation data regarding location/movement of active calls. The host processes the input data with reference to known cell neighborhoods, and creates output data for each cell that includes information on other active calls in the neighborhood. The output data then updates the cell with information regarding active calls in the cell's vicinity. The cell may then make adjustments to call variables taking into account local interference conditions. Further, through reference to (1) fixed data regarding the network such as topography or statistics, and/or (2) immediate past historical data regarding active calls, the host may also create output data taking into account predicted impending interference conditions.

Title: Dynamic channel allocation in macrocells with deterministic exclusion for allowing underlaying autonomous microcells
Inventor: I CHIH-LIN
IPC: H04W16/14
Filed: 1998-07-23
Abstract: Co-Existence Dynamic Channel Assignment (DCA) techniques for overlay macrocellular systems facilitate the coexistence of embedded autonomous underlay microcellular (e.g., indoor) systems. The co-existence of the two systems without excessive mutual interference is achieved through systematic deterministic exclusion of predefined subsets of the universal channel set from the dynamic assignment to the overlay macrocells. The sets of channels are made available to the underlay systems. The exclusion is done with minimal DCA performance degradation. Multiple deterministic exclusions methods are described.

Abstract: Protéines de fusion de CTLA4-immunoglobuline présentant des fonctions d'effecteur par la région constante d'immunoglobuline modifiées, et acides nucléiques codant les protéines de fusion. Les protéines de fusion de CTLA4-immunoglobuline sont constituées de deux éléments: un premier peptide présentant une activité CTLA4 et un deuxième peptide comprenant une région constante d'immunoglobuline modifiée pour réduire au moins une fonction d'effecteur biologique par la région constante d'immunoglobuline, par rapport à une protéine de fusion CTLA4-IgG1. Les acides nucléiques décrits peuvent s'intégrer dans différents vecteurs d'expression, lesquels peuvent à leur tour commander la synthèse des protéines correspondantes dans différents hôtes, en particulier les cellules eucaryotes. Les protéines de fusion de CTLA4-immunoglobuline décrites ici peuvent être administrées à un sujet pour inhiber une interaction entre un ligand DTLA4 (par exemple, B7-1 et/ou B7-2) sur une cellule présentant un antigène et un récepteur pour le ligand CTLA4 (par exemple CD28 et/ou CTLA4) à la surface de cellules T pour supprimer ainsi une réponse immunitaire du sujet, par exemple pour inhiber le rejet de transplantation, les réaction de greffon contre l'hôte ou les réactions auto-immunes.

Title: In vitro assay for identification of carcinogens
Inventor: KOWALSKI LINDA A
IPC: C12N15/09
Filed: 1997-04-04
Abstract: Disclosed is a method to evaluate the carcinogenicity of a compound using a transformation assay. The method includes contacting a compound to be tested for carcinogenicity with a test cell. The test cell either includes a recombinant isolated nucleic acid molecule which encodes a cellular transforming protein or a modified genome which encodes a cellular transforming protein. Cell growth is scored to identify the presence or absence of a transformation characteristic, such as formation of foci, loss of growth factor or serum requirements or anchorage independence. The development of such a transformation characteristic indicates that the compound being tested is carcinogenic. Cellular transforming proteins of the present invention can include growth factors, growth factor receptors, intracellular transducers and nuclear transcription factors. Further embodiments include a method to evaluate the anticarcinogenicity of a compound, which includes contacting a compound to be tested for anticarcinogenicity with a test cell under conditions which, in the absence of the compound, the test cell is transformed.

Title: Balanced transversal i,q filters for quadrature modulators
Inventor: DENT PAUL W
IPC: H04B1/707
Filed: 1997-03-13
Abstract: Radio transmissions are spectrally contained to reduce adjacent channel interference by a method and apparatus for I, Q filtering of signals before quadrature modulation in digital cellular radio transmission systems such as communications systems following the GSM TDMA, IS-54 or IS-95 standards. The filtering is accomplished by multiple stage registers connected at their complementary outputs to identical resistor networks. The outputs of the resistor networks are summed to represent a smoothly transitioning analog representation of the digital voice or data transmission. The analog representation may be additionally low pass filtered to remove higher frequency components before quadrature modulation. Because rapid transmissions in the transmittal signal are avoided, adjacent channel interference is reduced.
