Title: User authentication in a communications network
Inventor: HARDING PETER MAXWELL
IPC: H04Q3/00
Filed: 1995-08-16
Granted: 1999-12-21
Abstract: An authentication system of a terminal on a public switched telephone network comprises a security node associated with a local exchange (10) and a network terminal (14). For one-way authentication, the terminal (14) responds to a call initiation by sending a unique authentication code (R) comprising a number (m) and a secret key (S¿j?) encrypted according to a first algorithm (F), the secret key being specific to the terminal. The security node constructs the expected authentication code (E) from the number (m), using the first algorithm (F) and a second key which is a function of a terminal identification number (TN), and compares the expected code (E) with the received code (R). In two-way authentication, the security node responds to the call initiation by sending a transaction number (n) to the terminal (14) encrypted according to a second algorithm (f¿j?). The terminal (14) generates the authentication code (R) as a function of the first algorithm (F), the secret key (S¿j?) and the transaction number (n). The authentication code (R) is sent back to the security node. An expected code (E) is compared with the received one (R) in the same way. In both cases, a match between expected and received authentication codes (E and R) constitutes authentication of the terminal (14), allowing the user access to the network.

Abstract: A new throat bushing for use with rotary fluid equipment (10) having a seal cavity (28) defined by a shaft (14), a shaft housing (13), and a seal (26) engaging the shaft, which includes an annular shaped element (50, 62, 66, 90, 92, 108, 120) for securement to the housing (13) at the entrance to the cavity. The shaft can pass through the element and rotate freely, without contact. A spiral groove (64, 88, 98, 122), or multiple spiral grooves, may be cut into the radial surface (60) facing towards the seal. The groove is configured to guide any abrasives radially inwardly, away from the cavity bore, toward the shaft. Through this mechanism, any contaminants are easily removed from the seal cavity by the use of a minimum flow of clean flush injected into the seal cavity.

Abstract: On a découvert que l'apoptosine ne réussit pas à induire l'apoptose chez des cellules humaines normales mais peut induire l'apoptose chez des cellules normales transformées. L'apoptosine induit chez diverses cellules cancéreuses humaines un type distinct d'apoptose en p53 et ne peut pas être bloquée par différents agents inhibiteurs de l'apoptose. L'invention concerne un agent anticancéreux qui tue spécifiquement des cellules cancéreuses et pas des cellules normales. L'invention concerne en outre l'induction de la mort cellulaire par thérapie génique. L'apoptosine peut induire l'apoptose chez des cellules cancéreuses animales non humaines. On a découvert également que l'apoptosine se retrouve surtout dans le cytoplasme des cellules normales, alors que dans les cellules cancéreuses, elle se retrouve dans le noyau.

Abstract: The primary cable of compressed conductor is properly a low tension primary cable with the particularity of having a same sectional area that permits to conduct , the same amount of electric current to any part of an automotive vehicle. However, its external diameter is much more smaller related to a same caliber of the same nature because of the compression that it suffers during the process of the compacted joining in a joining machine.      The cable of compressed conductor has several advantages over other conventional primary cables, since a bigger standardization in the insulator thickness is found and in this way, a standardization on the results of the chemical-physical, and mechanical tests is accomplished. (these tests are compulsory because of its design.)

Abstract: A composition including polyalphaolefins that function as drag reducing agents and a process for the preparation of polyalphaolefins that function as drag reducing agents are disclosed. The process includes contacting alphaolefin monomers with catalyst particles in a polymerization mixture that includes a hydrocarbon solvent.      The polymerization of the alphaolefin monomers produces polyalphaolefin drag reducing agents having an inherent viscosity of at least 10 dL/g. During polymerization of the polyalphaolefin monomers, localized micelles compromising high molecular weight polyalphaolefin polymer are formed in micellar zones around the catalyst particles. The polymerization is conducted in the presence of a viscosity reducing agent that includes a substantially hydrophobic dispersant. The viscosity reducing agent is present in an amount sufficient to reduce the viscosity of the reaction mixture and disperse the localized micelles. The addition of the dispersant during the polymerization process provides for high molecular weight polyalphaolefin and a more uniform molecular weight distribution of the resulting polyalphaolefin. A process of forming a polyalphaolefin drag reducing agent in one or more polymerization reactors and a process for reducing drag in a conduit are also disclosed. By dispersing the polyalphaolefin throughout the drag reducing agent, the present invention shows improved drag reduction. Additionally, the invention provides a more uniform molecular weight distribution which further increases the efficacy of the drag reducing agent by providing more consistent drag reducing capability.

Abstract: A rotating blowout preventer and method is disclosed that includes a flexible bladder that defines a pressure chamber radially outwardly of the bladder for direct activation of the bladder to allow for gas tight sealing along the variable profile of drill pipe and the irregular shape of the kelly. The pressure chamber for activating the bladder is preferably defined within the rotating seal assembly. As well, the rotating seal assembly includes both the bladder and the bearings. A pressure drop element is included within the hydraulic flow line through the rotating seal assembly so that the upper seal and bearing have a significantly reduced pressure drop for increased lifetime operation. The rotating seal assembly is hydraulically secured within the rotating blow-out preventer housing, preferably by remote control, by means of a preferred single cylindrical latch piston that moves upwardly and downwardly substantially parallel to the well bore axis. The latch piston wedgeably moves latch dogs radially inwardly to effect latching. After the latch piston is moved from the latch position, the latch dogs move radially outwardly as the rotating seal assembly is lifted from the rotating blow-out preventer housing as by a rig cat line to thereby effect quick change out of the bearings and/or the bladder.
