Such a folder-gluey comprises two frames between which are arranged two lateral conveyors (100, 110), the conveying means of which being belts (101, 111). The conveyor of the present invention comprises a structure consisting of four associated components (4, 5, 8, 11) which are transversely movable between the frames of the folder-gluer with respect to the travelling direction of said plate-like workpieces. Among these components of this structure, an upper longitudinal bar (4) can easily be manually lowered, in a vertical slanted movement, from a working position to a retracted position, and inversely raised by independent damping means (15). The central conveyor (1 ) can be retracted between the two lateral conveyors (100, 110) thus enabling the folder-gluer to be used in a new configuration where uncoupling of the transmission means necessary for the independent drive of the belt (30) is not required and which belt (30) is rotatable even in the retracted position. This conveyor allows to arrange the two lateral conveyors (100, 110) side by side so that the useable conveying width of the folder-gluer is reduced to a minimum value.

Granted: 2004-11-09
Abstract: The present invention provides broadband multimedia communication over the standard circuit-switched public switched telephone network infrastructure (PSTN) and other physical or virtual circuit-switched infrastructures while simultaneously and transparently interoperating with the public Internet packet-switched infrastructure to effectively merge the capabilities of the two types of infrastructures into a seamless capability that can bring the benefits of using both types of existing switching infrastructures to large groups of users under the control of the same common and simple interface tools such as web browsers. The invention enables users to establish both packet-switched connections for sending or receiving content for which low-latency and unpredictable response times are not a problem (i.e. text, small graphics, e-mail, small file transfers); and circuit-switched connections for sending or receiving content that benefits from streaming data at fixed data rates, without contention for bandwidth from other users during a communication session, (i.e. video, voice, complex graphics and animations, or large file transfers). The broadband network of the present invention thus mates the convenience of point and-click on-demand Internet-type packet-switched connectivity with the continuity of a circuit switch connection, and bundles B channels, or controls connections on virtual circuit switches such as ATM or RSVP for the required bandwidth on-demand for video conferencing and other high-bandwith applications.

Title: Dvd-authoring system and method
Inventor: WALLACE GREGORY KENT
IPC: G11B27/034
Filed: 1999-01-21
Granted: 2004-01-13
Abstract: A DVD authoring system in a processor-based system removes an author from consideration of the DVD Specification during authoring. According to a preferred embodiment, the authoring system provides an authoring engine having an interactive graphical authoring interface, a data management engine, an emulator, a compiler, a multiplexer and a simulator. Using summary authoring data, the compiler builds a skeleton-form PGC layout structure comprising control PGC abstractions and router PGC abstractions. The compiler then resolves the PGC abstractions according to source-target connections.  During playback on a DVD player, the PGC abstractions form elements in a connection-switching abstraction superstructure. Accordingly, in response to DVD-consumer and other control events, a source PGC preferably determines target PGC information and then transfers control, via virtual connections through necessary router PGC abstractions, to a target PGC abstraction. The target PGC abstraction then correspondingly initiates playback of a movie chapter or displays a menu.

Abstract: Methods and apparatuses for increas-ing the leak-resistance of cryptographic systems using an indexed key update technique are disclosed. In one embodiment, a cryptographic client device maintains a secret key value as part of its state. The client can update its secret value at any time, for example before each transaction, using an update process that makes partial information that might have previously leaked to attackers about the secret no longer usefully describe the new updated secret value. By repeatedly applying the update process, information leaking during cryptographic operations that is collected by attackers rapidly becomes obsolete. Thus, such a system can remain secure (and in some embodiments is provably secure) against attacks involving analysis of measurements of the device's power consumption, electromagnetic characteristics, or other information leaked during transactions.  The present invention can be used in connection with a client and server using such a protocol. To perform a transaction with the client, the server obtains the client's current transaction counter. The server then performs a series of operations to determine the sequence of transformations needed to re-derive the correct session key from the client's initial secret value. These transformations are performed, and the result is used as a transaction session key. The present invention includes a sequence of client-side updating processes that allow for significant improvements in the performance of the corresponding server operations.

Abstract: La 2,3,2 Tétramine (3,7-diazanonane-1,9-diamine) est suggérée pour le traitement de la maladie de Parkinson et des démences caractérisées par des dommages de la mitochondrie, du fait de sa capacité à neutraliser intégralement les effets de suppression de la dopamine du MPTP chez les animaux de laboratoire jusqu'à 12 heures après l'injection de ce dernier, et à maintenir une protection partielle au niveau des tissus suboptimaux pendant une durée pouvant atteindre 36 heures. L'effet de l'injection de combinaisons de MPTP et/ou d'agents de réduction et/ou de xénobiotiques et/ou d'agents de dépigmentation sur les taux de dopamine, de nonrépinéphrine, de sérotonine et d'épinéphrine a démontré que MPTP et MPP+ agissent comme des agents de réduction qui mobilisent le cuivre et le calcium, et séquestrent le fer, et que la sensibilité de la dopamine à ces types de neurotoxines, aux xénobiotiques et au métaux peut être corrigée par l'administration de 2,3,2 tétramine, laquelle semble redistribuer les métaux entre les divers groupes d'unités de stockage et les métaux libres dans le cytosol et semble réguler les événements induits par les récepteurs, parmi d'autres effets antidotaux analogues à ceux de certaines polyamines endogènes.
