Abstract: A method of continuously producing paper pulp by integrating the process ste ps of impregnating fiber material and boiling the impregnated fiber material, the boiling being commenced with digesting liquo r containing white liquor of high sulphidity. According to the invention the process includes a pretreatment of the fiber material in a tan k (1) with a liquid containing alkali metal bicarbonate and alkali metal hydrogen sulphide. The pretreatment liquid is brought into contact wit h the fiber material under reducing pressure, whereby, through the pressure reducing and under the influence of heat in situ, said compound s from H2S, CO2 and alkali metal carbonate so that a part of the H2S and HS- formed is absorbed by or diffused into the fiber material, while said CO2 is withdrawn from the tank. A liquor is formed during the pretreatment, which contains said alkali metal carbonate and whic h is withdrawn from the fiber material.

Abstract: A method for copy protecting a record carrier is disclosed, in which method the copy protected record carriers are provided with a pattern of logical errors which cannot be corrected by the error correcting rules predefined for said record carrier. The pattern of logical errors represents access control information. The logical errors are generat ed during decoding the bit sequence read from the record carrier. Bit errors may be positioned in the bit sequence so as to counterac t de-interleaving which is part of an error decoding process in a reading device and accumulate in error words which are uncorrectable. Also a method for detecting access control information and a retrieval arrangement are disclosed, which retrieval arrangement serves to detect the access control information by selecting at least one error location, but not all error locations on the record carrier, and verifying the presence of an error by reading the selected error location via the reading means.

Abstract: L'invention concerne deux capteurs (78, 80) piézoélectriques, qui sont montés sur l'arrière d'une plaque (14) élastique d'un balayeur (10) à résonance mécanique en étant placés de chaque côté d'une ligne centrale coïncidant avec un axe de rotation (16). Tandis que le miroir (12) du balayeur est animé d'un mouvement rotatif de va-et-vient, les deux capteurs sont accélérés et décélérés à une différence de phase de 180·. La tension de sortie de chaque capteur passe par un niveau zéro lorsque l'accélération est constante. Un amplificateur (88) différentiel détecte les passages par zéro pour se déplacer le long de l'axe de rotation. Un taux d'élimination en mode commun élimine les accélérations non rotationnelles associées à des vibrations et à des chocs extérieurs et empêche que les passages par zéro du miroir ne soient masqués.

Abstract: Il est possible de diagnostiquer le syndrome de fatigue chronique par détection dans des conditions natives d'une molécule de RNase L d'environ 30 kDa dans des extraits cellulaires de cellules contenant de la RNase L telles que les cellules mononucléaires du sang périphérique. Les protéines sont fractionnées en fonction de leur poids moléculaire dans des conditions non dénaturantes. Les protéines fractionnées sont testées pour y rechercher de protéines d'environ 30 kDa présentant une activité enzymatique de RNase L dépendant de la 2-5A. La sévérité de l'affection peut s'évaluer en testant la présence de molécules de RNase L présentant des poids moléculaire approximatifs de 30 et de 80 kDa. La présence de molécules de RNase L d'environ 30 kDa et l'absence de molécules de RNase L d'environ 80 kDa est en corrélation avec un sévère syndrome de fatigue chronique. La présence des deux types de molécules indique un syndrome de fatigue chronique. Dans des conditions dénaturantes, et en présence d'inhibiteurs de la protéase, le syndrome de fatigue chronique peut être diagnostiqué par détection d'une protéine de liaison 2-5A d'environ 37 kDa.

Title: Electrical switchgear with synchronous control system and actuator
Inventor: DUNK MICHAEL PETER
IPC: H01H33/59
Filed: 1999-06-24
Granted: 2003-01-07
Abstract: In a power distribution system, synchronizing switchgear operations with an AC voltage or current waveform can be accomplished more precisely with a closed-loop feedback, microprocessor-based motion control design. By employing a closed-loop feedback, microprocessor-based design, switchgear contact position and velocity can monitored and optimized in real-time during a switching operation, thereby assuring a more accurate switching operation. Moreover, the closed-loop feedback design intrinsically compensates for the affects of such things as ambient temperature, AC waveform fluctuations, and changes in the physical condition of the switchgear. The closed-loop position feedback design is also capable of optimizing various transfer function parameters associated with the closed-loop feedback process, both during and subsequent to a switching operation, to further assure that switching operations are more accurately synchronized with the AC voltage or current waveforms.

Abstract: A connector plug can be removably snap-fitted into the adapter which has a cavity into which the connector plug is inserted and a hole for locking the connector plug. The connector plug has: an optical fiber; a ferrule; housing; an elastic engagement piece with an projecting engagement portion and a projecting press portion, the engagement portion being adapted to snap into the hole of the adapter and become locked there when the connector plug is inserted into the adapter; and a stopper for locking the elastic engagement piece from being pressed. A height of the projecting press portion is set almost flush with a surface of the housing of the adapter, or is set almost equal to the height of the receptor portion of the adapter.      Therefore, the connector plug can easily be connected to and disconnected from the adapter and its connection with the adapter is not easily broken.

Granted: 2010-12-07
Abstract: A telecommunications network architecture provides transport and switching of user services, particularly PSTN/ISDN services. In the network, connections are set up between end points which typically comprise narrow band exchanges serving subscribers. Calls are set up between the end points via call servers using e.g. ISUP signalling between the end points or exchanges and the call servers.    The call servers set up connections via a concatenated series of paths or tunnels across an intermediate MPLS network via media gateways serving respective nodes in the MPLS network. User information packets are carried across the MPLS network by the attachment of an appropriate label, this label being removed on egress from the MPLS network to recover the original packet.
