Title: Http distributed remote user authentication system
Inventor: REICHE ALBERT F
IPC: H04L29/06
Filed: 1997-11-25
Abstract: The present invention relates to the field of data and computer network security. Data and computer network security is of the utmost importance to most organisations that possess such networks. One of the difficulties that users and managers of these networks face is that the users have to provide a user ID and password every time they wish to access one of the organisation's secured HTTP servers or URLs. This creates a problem for users and managers since lists of numerous user IDs and passwords need to be maintained and therefore can easily be lost or their confidentiality compromised. This invention addresses these problems by providing a transparent, scalable, single point of authentication for remote users across any number of HTTP servers anywhere on a data network, such as an Intranet, using any user ID and password scheme implemented by a main authentication HTTP server.

Title: Poutre maltem
Inventor: MALOUIN JEAN-MARC
IPC: E04B5/10
Filed: 1998-02-16
Abstract: Dans la façon habituelle de construire une habitation -ou un bâtiment commercial de petite envergue- l'utilisation de poutres de bois pleines ou de madriers assemblés outre leur installation plus complexe, due entre autres aux étapes de nivelage et de mesurage qu'elles demandent, font subsister d'autres inconvénients. D'abord, les poutres pleines ne permettent pas le passage de composantes primaires (fils, conduits,...) et l'on ne peut les percer pour ce faire. Cette problématique se présente surtout lors du montage de la structure. D'antre part, les poutres dites conventionnelles de soutènement, sont toujours apparentes et posent problèmes lors des travaux de recouvrement de plafonds entre autres. Une poutre de soutènement affleurée, ajourée et d'un matériau plus fort que le bois pourrait combler ces lacunes et sauver du temps lors de l'assemblage des poutrelles secondaires (de planchers).

Abstract: Le gène d'activation des lymphocytes (LAG-3), qui est un membre de la superfamille des immunoglobulines, est transcrit sélectivement dans les lymphocytes T et les cellules tueuses naturelles activées de l'homme. Il y a une corrélation entre l'expression de la protéine de surface LAG-3 et la production d'IFN-.gamma. dans les lymphocytes T stimulés par un antigène, mais pas celle d'IL-4, et cette production est stimulée par IL-12. Cette production est associée, de préférence, avec les lymphocytes T CD4+ produisant des cytokines du type Th-1. La présence de LAG-3 sur la surface des lymphocytes Th1 est utilisée comme marqueur pour détecter et identifier les lymphocytes Th1 et les distinguer des lymphocytes Th2. On utilise des anticorps monoclonaux dirigés contre LAG-3 pour détecter et isoler les cellules Th1, ainsi que pour diagnostiquer des maladies associées à Th1. La présente invention concerne également des procédés de traitement de maladies infectieuses, du cancer et de troubles associés à un déséquilibre Th1/Th2.

Abstract: In order to supply the base bias voltage of bipolar IC current source transistors with a band gap reference circuit that supplies a temperature-dependent and resistance tolerance-dependent base bias voltage so that the current supplied by the current source transistors causes a constant voltage drop in the load resistances through which the current flows, the base bias voltage is supplied by a distributor circuit connected downstream of the load resistances and having an input stage, an output driver and an intermediate inverter composed of a first transistor, a first resistance, a second transistor and a second resistance mounted in series and connected to the supply voltage. In order to supply the base bias voltage to current source transistors having another type of resistance than that for which the band gap reference circuit is designed, the corresponding distributor or converter circuit has a second resistance of the same type as that of the resistance for which the band gap reference circuit is designed, and a first resistance composed of a resistance of this same type connected in series to the other type of resistance.

Inventor: HOSHINO NOBUAKI
IPC: F24J3/00
Filed: 1998-02-25
Abstract: A viscous fluid type heater includes a heating chamber for holding viscous fluid and a rotor located in the heating chamber.  A holding chamber is located below the heating chamber to communicate with the heating chamber.  A plunger, which is actuated by a solenoid, is movable between a forward position for maximizing the volume of the holding chamber and a rearward position for minimizing the volume of the holding chamber.  When the plunger is at the forward position, viscous fluid is discharged from the heating chamber to the holding chamber.  When the plunger is at the rearward position, viscous fluid is supplied from the holding chamber to the heating chamber.  This allows the load of the heater to be removed or reinstated selectively. In an engine-driven vehicle, the engine can thus started without being hindered by the heater.

Abstract: A utility knife has a blade magazine (18) removably mounted in a manually holdable housing (12) and rotatable about an axis parallel to a longitudinal axis of the housing (12). The blade magazine (18) has a series of radially and longitudinally extending circumferentially spaced blade-receiving slots (20) for separately receiving thin blades (22) having a cutting edge (24) at at least one end thereof, each slot (20) having an open front end to enable a blade (22) therein to be removed from the magazine (18) by forward movement through the front end of the slot (20). The housing (12) also carries a slidable transport mechanism (42) having a manually engageable actuator (44) projecting from the housing (12) and slidable in a longitudinal direction between front and rear positions, the transport mechanism (42) also having a blade-engaging arm (112) within the housing (12). Positioning of the actuator (44) at the forward position causes a blade (22) carried by the arm (112) to project from the front end of the housing (12) in an operative position, and movement of the actuator (44) from the forward position to the rear position causes the blade (22) to be retracted from the operative position into the housing (12) and into an empty slot (20) in the magazine (18). The magazine (18) is rotatable to move the retracted blade (22) from the arm (112) of the transport mechanism (42) and to position a new blade from another slot onto the arm for subsequent movement by the actuator to an operative position.

Title: Microparticle enhanced light scattering agglutination assay and microparticle reagents therefor
Inventor: EDA SHINICHI
IPC: G01N33/543
Filed: 1998-07-29
Abstract: The invention relates to a new microparticle enhanced light scattering agglutination assay for determining the amount of an analyte, and a microparticle reagent for performing that assay. The microparticle enhanced light scattering agglutination tests are quasihomogeneous and do not need a separation and washing step. They thus meet the requirements for the automation with commonly used clinical chemistry analyzers or dedicated nephelometers. Such tests provide an increased sensitivity by a factor of 2 to 3 orders of magnitude (down to 10 -11 mol/l analyte) compared to direct agglutination tests not using microparticles and, in addition, less matrix interference and higher flexibility. The specification provides a microparticle enhanced light scattering agglutination assay for determining the amount of an analyte which comprises using a mixture of particles of strong light scattering properties carrying at least one binding partner of high reactivity for the analyte and particles of weak light scattering properties carrying at least one binding partner of low reactivity for the analyte. The assay of the invention shows an unexpectedly high dynamic range (DR).
