Patent CA-2253632-A1 (CA)
Inventor: BOCZKOWSKI DAVID J
IPC: C07K14/47
Filed: 1997-04-30
Abstract: Disclosed are cells and methods for treating or preventing tumor formation or infections with pathogens in a patient. The cells of the invention are antigen-presenting cells (e.g., dendritic cells or macrophage) that have been loaded with RNA derived from tumors or pathogens. By administering the RNA-loaded antigen-presenting cells to a patient, tumor formation or pathogen infections can be treated or prevented. Alternatively, the RNA-loaded cells can be used as stimulator cells in the ex vivo expansion of CTL. Such CTL can then be used in a variation of conventional adoptive immunotherapy techniques.

Title: Novel nucleoside analogs with polycyclic aromatic groups attached, methods of synthesis and uses therefor
Inventor: KOOL ERIC T
IPC: C12Q1/68
Filed: 1997-05-15
Abstract: The present invention provides fluorescent nucleosides carrying polycyclic aromatic hydrocarbons such as anthracene, phenanthrene, pyrene, stilbene, tetracene or pentacene. The subject nucleosides may be synthesized using a C-glycosidic bond formation method employing organocadium or organozinc derivatives of the aromatic compounds and coupling with a 1-.alpha.-chlororibose or deoxyribose synthon. The .alpha.-anomers of the coupling reaction may be epimerized to the .beta.-anomers by acid-catalyzed equilibration. The fluorescent nucleosides act as a DNA or RNA base analogs and can be incorporated into nucleic acids. Resultant fluorescently tagged nucleic acids are useful as probes for target nucleic acids in tissues, solutions or immobilized on membranes.

Title: Method and apparatus for coordinating internet multi-media content with telephone and audio communications
Inventor: HONORE FRANCIS A
IPC: H04M3/56
Filed: 1997-05-07
Abstract: Methods and an apparatus are described whereby Internet content is coordinated with audio communications, such that two or more parties can view the same media content on the Internet while also simultaneously communicating over a traditional telephony network or by using voice over network implementations.  The visual interaction is achieved by having a user computer display shared content that correspond to a second computer's display, such that both parties will be viewing a copy containing the same content on each of their browsers.  The visual interaction further provides a method for allowing either of the parties to update the visual content of their browsers. In a further embodiment the resource collection functions of the user computer are enhanced by having the server only download to the user computer a user applet containing the information required by the user computer as is necessary. In this way, the user computer does not have to wait as long or dedicate resources to the visual interaction that are not necessary at the time. In a further embodiment this method works through firewalls on the network.

Title: Process for coating the flow channels in a monolithic catalyst carrier with a coating dispersion
Inventor: PIROTH JOSEF
IPC: B01J37/02
Filed: 1999-08-19
Abstract: The invention relates to a process for coating the flow channels in a monolithic, cylindrically shaped catalyst carrier with a coating dispersion, wherein the carrier has two end faces which are connected to each other by flow channels arranged parallel to the axis of the cylinder, by vertically aligning the axis of the cylindrical carrier, placing a predetermined amount of coating dispersion from a storage container on the upper end face of the carrier and drawing the dispersion through the flow channels under suction, removing excess coating dispersion from the flow channels by emptying the flow channels under suction, returning the excess dispersion to the storage container and fixing the dispersion coating by calcination. The process is characterised in that the coating dispersion is drawn through the flow channels under suction at a rate of flow of 0.1 to 1 m/s and that after completion of passage under suction the excess coating dispersion is removed from the flow channels by applying a suction impulse from below, wherein the suction air is drawn through the flow channels under suction at a rate of flow between 40 and 1 m/s and the excess coating dispersion discharged with the air stream is separated from the air stream within a time of less than 100 ms after discharge from the catalyst carrier.

Abstract: During a succession of working cycles, a sound synthesizer system for obtaining at an output a series of electrical samples produces first level samples from zero level samples which can come from diverse sources. The samples are produced allowing for parameters such as the frequency, amplitude, phase or a filter coefficient. All of the data used in establishing samples is processed in cells materialized by locations of a plurality of memories. The content of the cells can evolve from one working cycle to the other and data calculation means are used on a timesharing basis for all the cells. The first level samples can be selectively combined to form second level samples before they are transferred to an output.
