Patent CA-2071413-C (CA)
Inventor: ROHLAND WILLIAM S
IPC: G06F21/00
Filed: 1992-06-17
Granted: 1999-01-05
Abstract: Le dispositif A dans un réseau de chiffrement à clé publique sera limité pour continuer à pratiquer fidèlement une politique de sécurité émise par un centre de certification du réseau, longtemps après la certification de la clé publique PUMa du dispositif A. Si un dispositif A modifie ses opérations au-delà des limites encodées dans son vecteur de configuration, par exemple en chargeant un nouveau vecteur de configuration, le dispositif A se verra refuser la participation au réseau. Pour réussir à appliquer la politique de sécurité du réseau dictée par le centre de certification, ce dernier doit vérifier qu'au moment de la demande de certification de sa clé publique PUMa, le dispositif A est configuré avec le vecteur de configuration autorisé. Le dispositif A est nécessaire pour transmettre au centre de certification une copie de son vecteur de configuration actuel, dans une fiche de vérification. Le centre de certification compare alors la copie du vecteur de configuration du dispositif A au vecteur de configuration autorisé pour le dispositif A entreposé au centre de certification. Si la comparaison donne des résultats satisfaisants, le centre de certification émettra le certificat demandé et produira une signature numérique dSigPRC sur une représentation de la clé publique PUMa du dispositif A, à l'aide de la clé de certification privée PRC du centre de certification. Si le dispositif A essaie, par la suite, de changer son vecteur de configuration, la clé privée PRMa du dispositif A correspondant à la clée publique certifiée PUMa sera automatiquement mise hors d'utilisation pour fins de communications au sein du réseau.

Title: Vector with multiple tat activation response elements affecting gene expression
Inventor: LISZIEWICZ JULIANNA
IPC: A61K48/00
Filed: 1991-01-16
Granted: 2004-05-11
Abstract: The present invention relates to viral inhibition, particularly HIV inhibition, by DNA sequences including multiple target response elements. This is the first time that a construct, proposed for gene therapy use, is under the control of a biological regulation. The protective gene product will only be expressed, if the cell becomes infected and a viral protein is made. The DNA construct of the present invention comprises a vector and a promoter operably linked to multiple tat activation response elements so that the elements are transcribed in tandem.      The DNA construct can be used in the treatment of viral infections, in particular HIV associated diseases, by obtaining cells from an HIV-infected patient, transforming the cells with the construct and administering the transformed cell to the patient.

Abstract: A drawn and ironed container (C) that includes a cylindrical side wall, a smoothly-tapered neck (134) with an open end and an integral bottom wall (137) at the opposite end has a plurality of inwardly-deformed panel segments (130) located in the side wall between adjacent arcuate segments (132) with the panel defin-ing generally chordal bottom walls for the panel seg-ments. The container is formed using a multi-station processing apparatus that consists of a plurality of identical stations (30) located around the periphery of a rotating turret (26). Each station includes a support mandrel (50), a container loading means (52, 53) and an impression mandrel (54), with the impression man-drel being pivoted into and out of pressure engage-ment with the support mandrel to deform the side wall of the container. The support mandrel has a cylindri-cal peripheral surface (102) that conforms to the inner diameter of the container side wall and has circumfer-entially-spaced, axially-extending pockets (104). The pockets have sharp opposite edges (108a) that cooper-ate with the impression mandrel to produce the panel segments in the side wall.

Filed: 1993-04-07
Granted: 1996-03-26
Abstract: A four color toner single pass color printing system consists generally of a raster output scanner (ROS) optical system and two tri-level xerographic units in tandem. Only two of the three subtractive primary colors of cyan, magenta and yellow areavailable for toner dot upon toner dot to combine to produce the additive primary colors. The resulting color printing system would be able to produce pixels of black and white and five of the six primary colors, with pixel next to pixel printing producing all but the strongest saturation of the sixth primary color, an additive primary color. The color printing system uses either four color toners or a black toner and three color toners.

Granted: 1997-07-15
Abstract: A visco-elastic polymer liner for use in donning over a residual limb and fitting within the socket of an artificial limb.  The liner is shaped to have its cavity formed with a volume and shape less than a volume and shape of the residual limb for both tension and tissue configuration relief while the liner has an outer surface formed with a volume and shape greater than the volume and shape of the artificial limb socket for relief of certain tissue configurations and to create weight bearing, relief and compression areas on and in the liner to absorb and dissipate shock, shear and mechanical forces through the liner otherwise transmitted to the residual limb.  The liner may have imbedded on its inner cavity side electrodes adjacent muscles that are sensitive to the muscle action potentials to generate signals to a power source to move an articulable artificial limb.  The liner may take the shape of a tube to be donned over a paralyzed limb similarly having electrodes imbedded in its inner cavity side adjacent neuromuscular junctions which are connected to a muscle action potential generator to activate flexion and extension of the paralyzed limb.  A method for making the liner is also claimed which comprises the making of a positive model of the residual limb, reducing the model, forming the liner about the reduced model and laminating a hard socket over a reduced model of the liner.

Title: Process for high purity tetrabromobisphenol-a
Inventor: MCKINNIE BONNIE G
IPC: C07C37/82
Filed: 1993-03-19
Granted: 1999-01-26
Abstract: The purity of a tetrabromobisphenol-A(TBBPA) product can be enhanced so as to make it more valuable as a flame retardant by contacting it with a quality-enhancing amount of water having a resistivity >50,000 ohms and subsequently heat-treating it to provide a TBBPA product containing <20 ppm of total ionic impurity. The tetrabromobisphenol-A product subjected to this treatment may be a TBBPA prepared by any known process but is preferably a TBBPA having a low organic impurity content and most preferably a TBBPA prepared by (1) adding 3.9-4.2 molar proportions of bromine and optionally also a methanol solvent to a solution of one molar proportion of bisphenol-A in a methanol solvent while maintaining a reaction temperature in the range of 0-40°C, (2) optionally adding more methanol solvent, and (3) precipitating the TBBPA thus formed after bromination is substantially complete; the methanol solvent of steps (1) and (2) containing less than 5% by weight of water and being used in a total amount in the range of 25-43 molar proportions.

Title: Prosthetic heart valve
Inventor: BOKROS JACK C
IPC: A61F2/24
Filed: 1993-09-10
Granted: 2003-08-19
Abstract: Bi-leaflet heart valves (10, 91) have valve body contours and pivot arrangements that create quick valve response to flow reversal. Valve members or leaflets (14, 95), which can have flat or curved inflow and outflow surfaces, are slidably and pivotally mounted in a heart valve body (12, 93) of contoured profile so they can be aligned precisely parallel to blood flow in the open position. The leaflets engage either projections (26, 28) extending radially inward from flat wall sections (24) in the valve body sidewall or grooves (101, 103) in flat wall sections (117). The shape and relationship of these interrogating surfaces, together with a centrally directed surge of backflowing blood which results from the strategic location of a pair of downstream side openings provided by recesses (45, 114a) in the annular valve body, cooperate to provide prompt closing rotation of the leaflets from a parallel open orientation.
