Abstract: An authentication method (30) that permits a user (12) and a file serving workstation (13) to mutually authenticate themselves. This is accomplished by exchanging a random number that is encrypted by a password (22) that is known to the user (12) and stored in a password file on the file serving workstation (13). A logon ID (21) is sent from the client workstation (11) to the server workstation (13). The stored user password (22) corresponding to the user ID (21) is retrieved from the password file. A random number is created that is encrypted by a symmetric encryption algorithm on the server workstation (13) using the retrieved user password (22), and which provides an encrypted password (24). The user (12) is then requested to enter the password (22) into the user workstation (11). The entered password (22) is used to decrypt the encrypted password (24) received from the server workstation (13) and retrieve the random number therefrom to authenticate the server workstation (13). The random number is then used as the encryption and decryption key for communication between the user and server workstations (11, 13). An encrypted message is transmitted using the random number from the client workstation (12) to the server workstation (13). The encrypted message is decrypted at the server workstation (13) to authenticate the user (11).

Abstract: A system for disinfecting the water lines of a dental unit is provided with first and second unidirectional check valves. Water at a first pressure is normally supplied to the water lines of the dental unit through the first check valve. A reservoir of liquid disinfectant can be pressurized at a second pressure higher than the first pressure by the air compressor already equipping the dental unit to supply disinfectant to the water lines of the dental unit through the second check valve. Liquid disinfectant is prevented from reaching the water supply line by the first check valve. In the same manner, when the reservoir is not pressurized, the second check valve prevents water from the water supply line from reaching the disinfectant. The reservoir is formed with an upper neck and a bottom, and the disinfectant system is provided with a housing on which an upper stopper fitting into the neck and a lower reservoir bottom support are mounted, whereby for mounting the reservoir on the housing, one successively tilts the reservoir, places the neck on the stopper and slides the reservoir bottom on the support, which sliding movement is facilitated by a rounded edge of the reservoir bottom.

Abstract: Attachment means for attaching a flexographic printing form, particularly a printing form of photopolymeric material, on a plate cylinder, is provided with a flexible supporting layer and a photopolymeric layer supported by the supporting layer being fully exposed. In order to obtain a particularly effective attachment means the adherent characteristics of a photopolymeric layer are advantageously utilized. Experiments have shown that these adherent characteristics are also maintained in case of intensive use during at least 8 to 12 months. Moreover, on the one hand a good attachment of the printing form on the plate cylinder is achieved, whereas on the other hand the printing form can relatively easily be removed from the adherent photopolymeric layer and no residual photopolymeric material remains on the printing form. In this way a long lifetime of the attachment means applied on the plate cylinder is achieved, while on the other hand the printing form needs no longer undergo any cleansing treatment. Damaging of the printing form by removal is excluded as well so that the printing form is more times available for repeat order without any problem.

Abstract: Méthode et dispositif de mesure de la concentration de l'urée ou d'une substance similaire, dans une solution composite, notamment une solution de dialyse, par décomposition catalytique de l'urée par l'uréase. On mesure la différence de conductivité entre la solution ayant subi la réaction et la solution ne l'ayant pas subi, cette conductivité étant proportionnelle à la concentration d'urée. La décomposition s'opère selon la réaction suivante: (NH2)2 CO + CO2 + 3H2O } 2NH4<+> + 2HCO3<-> (5). Sous l'effet de l'addition (41, 60) de dioxide de carbone sous forme gazeuse et de la catalysation par l'uréase, la réaction se déplace vers la droite, ce qui signifie que cette proportionalité s'applique sur une vaste plage de concentrations d'urée, jusqu'à et même au-delà de 35 mM. L'addition de dioxide de carbone sous forme gazeuse assure également une valeur de pH suffisamment basse dans la solution pour prévenir la précipitation de carbonate de calcium.

Abstract: This is a braided tubular device used in the occlusion of various lumen or cavities in the body. In particular, it may be used to form an endovascular occlusion. Most desirably, it is braided of a majority of super-elastic alloy ribbons and therefore is both inherently non-stretching and most difficult to permanently deform. It may be deployed using an electrolytically severable joint. A radio-frequency modulated current may optionally be applied to the device after its placement in the body. The elongated device preferably is insulated along its length to optimize its occlusive activity without harm to the body.
