Patent CA-2197058-A1 (CA)
Title: Anti-inflammatory agent
Inventor: ROTSTEIN ORI D
IPC: C12N5/08
Filed: 1997-02-07
Abstract: Alterations in the cellular redox state play a critical role in cell signaling and cell activation, suggesting that administration of sulflhydryl-reactive agents have important modulatory effects on the inflammatory response. Intracellular thiol depletion attenuates the pulmonary inflammatory response following intratracheal administration of endotoxin (LPS), and this attenuation supersedes the reduction in antioxidant defenses associated with depletion of the endogenous antioxidant, glutathione (GSH). Sprague Dawley rats were administered diethylmaleate (DEM, 6 mmole/kg), a rapidly acting GSH-depleting agent, followed by intratracheal administration of LPS. Lung injury was assessed by measuring the transpulmonary flux of 125l albumin and expressed as a permeability index (Pl). Administration of DEM reduced lung GSH levels from 1310~114 to 185~48 nmoles/g. This was associated with a reduction in the Pl following LPS treatment (LPS: 0.22~0.03 vs LPS+DEM: 0.03~0.01). Bronchoalveolar lavage fluid PMN counts were markedly reduced in animals pretreated with DEM (LPS: 90.5~24x106 vs LPS+DEM: 1 .9~0.4x106). The reduction in lung neutrophil sequestration was not due to an effect on the neutrophil, as peripheral blood PMN isolated from DEM-treated animals had equivalent chemotactic responses to fMLP, and normal upregulation of CD11b. DEM pretreatment mitigated LPS induced upregulation of lung lCAM-1 protein and mRNA expression as demonstrated by immunohistochemistry and Northern analysis, respectively. DEM attenuates LPS-induced lung injury by preventing lung PMN sequestration. This effect appears to be mediated through abrogation of endothelial lCAM-1 upregulation in response to LPS. These data suggest that intracellular thiols modulate lCAM-1 expression.

Abstract: La présente invention concerne un procédé de transformation et de récupération des explosifs non utilisés, principalement des explosifs militaires contenant à la fois des substances cristallines fusibles et non fusibles. Selon cette invention, l'explosif non utilisé est traité en plusieurs étapes, la première étant une étape de lixiviation durant laquelle on extrait le composant non cristallin, de préférence fusible, de l'explosif sous forme de trotyl, de cire ou de plastic. La substance utilisée lors de l'étape de lixiviation, de préférence du toluène, n'altère pas les composants cristallins de l'explosif. Le liquide recueilli après lixiviation est ensuite séparé, puis le toluène, ainsi que la cire ou le trotyl dissous qu'il contient, est ensuite acheminé vers une autre étape de transformation. Le toluène recueilli lors de la transformation est renvoyé dans le système de traitement alors que les produits issus de l'étape de filtration sont traités à l'aide d'un solvant afin de dissoudre, respectivement, l'octogène et l'hexogène cristallins hautement explosifs qui sont concernés. Lors de l'étape de traitement suivante, ces explosifs sont précipités sous forme de nouveaux cristaux prêts à l'emploi, après une éventuelle recristallisation. Le solvant utilisé lors de cette opération est renvoyé dans le système de traitement.

Title: Process for activating polysaccharides, polysaccharides made by this process and their use
Inventor: STEINMEIER HANS
IPC: C08B1/00
Filed: 1996-03-22
Abstract: The invention concerns a process for activating polysaccharides, wherein the polysaccharide starting material is brought into contact with liquid ammonia at an initial pressure which is higher than atmospheric pressure and at a temperature of at least approximately 25 ~C, the amount of liquid ammonia being sufficient at least for wetting the surface of the polysaccharide starting material which is then expanded. The volume available for the polysaccharide/liquid ammonia system is enlarged in the manner of an explosion by lowering the pressure by at least 5 bar. The process is particularly suitable for activating cellulose, guar gum, starch and chitin. The process enables cellulose to be modified in a novel manner. The activated polysaccharides display higher reactivity and improved elimination of reagents during acylation, alkylation, silylation, xanthogenation and carbomoylation with largely homogeneous reaction processes.

Abstract: In accordance with the present invention, a general antenna system is disclosed suitable for applications in which an RFID Tag passes by an Interrogator. We then disclose a specific antenna design that uses a single planar antenna fortransmit and a multi-element planar antenna array for receive. The multi-elementplanar antenna array is spaced such that each of the planar elements is four inches apart, center-to-center, thus defining a narrow 30° receive beamwidth in the horizontal plane. The vertical receive bandwidth is much greater than 30°, facilitating the Interrogator receiving signals at a variety of elevations. Furthermore, a multi-way microstrip combiner is used to sum the signals received from each of the planar antenna.  To block interference from the transmit antenna and to improve receivesensitivity, this multi-way microstrip combiner is shielded using, in one embodiment, copper tape along its edges. In a specific embodiment, a four element receive antenna design is disclosed.

Title: Drywall-trimming article having curved surface covered with discrete fibers
Inventor: KOENIG JOSEPH
IPC: E04F19/02
Filed: 1997-10-30
Abstract: For trimming a drywall corner, a drywall-trimming article has an elongate portion and two flange portions, which are extruded unitarily with the elongate portion from polyvinyl chloride. The elongate portion has an arcuate profile. Each flange portion has an array of apertures. One of the convex and concave surfaces defined by the central portion is covered substantially with discrete fibers, which adhere to the substantially covered surface but which do not cover the remaining surfaces of the central portion and of the flange portions. Such adhering fibers facilitate application of a coat of paint and texturization of the coat of paint over the substantially covered surface without separating the inner surfaces of the flange portions from the underlying drywall by any appreciable thicknesses due to such adhering fibers. The apertures are substantially free of such adhering fibers so that drywall-finishing material, when pressed onto the outer surfaces of the flange portions, can be thus pressed through the apertures, into intimate contact with the underlying drywall, without intrusion of said adhering fibers that could interfere with bonding between such material pressed therethrough and the underlying drywall.

Abstract: The invention concerns a process for dispensing smart cards to smart card users from a magazine in a storage container. The smart cards are available in a non-predetermined way, without restriction to a particular provider or particular use. The smart cards at a point in time t1 contain those electronic components whose functions are sought before t1 by many undefined and unknown users for smart-card applications. For the purpose of loading a smart card with data and dispensing a smart card to a user, the smart card dispensing station can communicate via a user menu with a user during a period .DELTA.t between t1 and a later time t2. The user menu gives unambiguous and repeatable specifications regarding loading and dispensing. During the period .DELTA.t, the card dispensing station is connected via a cable- and/or radio-linked active communication adapter to an automatic or human-operated verification system. In the period .DELTA.t, the user can enter particular features via the user menu and data link into the dispensing station which transmits those features to the remote station; during the period .DELTA.t, the programs and/or data at the dispensing station can be modified by back-transmitted data and/or programs from the remote station. Personalisation, i.e. initial loading of the smart card with programs and/or data which are unique to and identify the card user, is done during the period .DELTA.t and the selection (controlled from the dispensing station) of a particular smart card from the magazine at time t2 takes place in such a way that the user operating the menu receives his own non-exchangeable card corresponding to the specifications which he or she entered via the menu and suitable for use as a smart card at some time after t2.

Abstract: Recovery of an insoluble polymeric sulfur species from the reaction solution of a hydrogen sulfide conversion process is enhanced by adding a sulfur debonding agent to the hydrogen sulfide conversion reaction solution either at the outset of the process or after conversion of the hydrogen sulfide. Conversion of the hydrogen sulfide initially produces a soluble complex having the polymeric sulfur bound therein. The sulfur debonding agent breaks the soluble complex to produce a free insoluble polymeric species readily separable from the reaction solution by conventional physical means to obtain the desired sulfur product.
