Abstract: Un ensemble d'appui et d'étanchéité pour supporter et sceller des parties d'extrémité d'un arbre rotatif à aubes dans les parois d'extrémité d'un malaxeur à mortier ou d'un appareil semblable. Chaque ensemble d'appui et d'étanchéité comprend un appui et un logement d'étanchéité fixés de manière amovible à une paroi d'extrémité du tambour malaxeur par des boulons pour faciliter le remplacement des appuis et des étanchéités lorsque cela devient nécessaire pendant l'utilisation. La paroi extérieure du boîtier comprend un anneau ou un épaulement périphérique pour un engagement avec un extracteur d'appui classique pour faciliter l'enlèvement du logement, des appuis et des étanchéités en une seule unité. Les unités de boîtier, d'appui et d'étanchéité préassemblées peuvent alors être utilisées comme pièces de rechange. Les appuis et les étanchéités sont également espacés longitudinalement pour fournir un espace pour les matériaux abrasifs qui peuvent migrer au-delà des étanchéités afin de prolonger l'espérance de vie des appuis en diminuant l'exposition à la contamination. Le boîtier comprend également une ouverture dans la partie inférieure de celui-ci communiquant avec l'espace entre les appuis et les étanchéités pour permettre au matériau qui migre au-delà des étanchéités de tomber à travers l'ouverture sur le sol, protégeant de ce fait les appuis de la contamination et indiquant à l'opérateur de malaxeur que les étanchéités sont usées ou sont défaillantes de telle sorte qu'il puisse en effectuer l'entretien ou le remplacement rapide.

Title: Paper pulp refiner control system and method using active hydrostatic bearings
Inventor: EGAN JOHN J III
IPC: D21D1/22
Filed: 2001-03-07
Granted: 2008-10-07
Abstract: A paper pulp refiner with control system employs active hydrostatic bearings for supporting the refiner rotor, at least in part, the hydrostatic bearings are defined between the refiner rotor plates (25, 55) and stator plates (22, 60) through openings (40, 62, 85) formed in the stator plates for the admission of active hydrostatic fluid. The control fluid flows into the refiner gap under controlled volume and pressure, employing the refining plates as active hydrostatic bearings and flows into the process fluid. Hydrostatic control fluid is used, which is non-contaminated to the process fluid. The rotors of the paper pulp refiners may also be controlled by hydrostatic bearing surfaces formed between relative rotating and non-rotating components, such surfaces having passageways also opening into the process fluid. In the event of loss of control or function, the refiner may continue to operate on the hydrostatic bearings until the control function can be restored.

Title: A technique for setting up calls in internet protocol mobile network
Inventor: BERTENYI BALAZS
IPC: H04L29/06
Filed: 2001-04-10
Granted: 2006-12-12
Abstract: In a technique for setting up calls in IP mobile networks, when an application level in a mobile station sends a setup message to set up a multimedia call, before sending such a message over the radio interface, the mobile station performs the appropriate procedures to setup the appropriate bearers over the radio interface and in the network to satisfy the call requirements specified by the application level in the setup message. The technique applies to both mobile originated calls and mobile terminated calls, the mobile station performing the transport level procedures after having received a setup message and before sending a confirmation/call acceptance message back to the calling party. Furthermore, the allocation of radio resources for PDP contexts that will be used to carry the media of a multimedia IP call is delayed so that no radio resources are allocated to the PDP contexts activated before the call control signaling is exchanged. The radio resources are allocated only when the call signaling has been completed and the called party has accepted the call and indicated the call characteristics that it can support. An indication is forwarded from the SGSN to the GGSN advising that no packets are to be sent on the PDP context because there are no radio resources for the PDP context. Quality of service negotiations for RAB are effected with an additional parameter that contains either a list of alternative values or the lowest acceptable value.

Filed: 1997-03-25
Granted: 2003-08-26
Abstract: A method and apparatus for producing a transition-controlled, DC-balanced sequence of characters from an input sequence of data bytes is disclosed herein. The bits in each of the data bytes are selectively complemented in accordance with the number of logical '1' signals in each data byte in order to produce selectively complemented data blocks. A cumulative disparity is then determined between the logical values of different type included within ones of the selectively complemented data blocks previously encoded into characters. In addition, a current disparity in a candidate character associated with a current one of the selectively complemented data blocks being encoded is also determined. The candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of a polarity opposite to a first polarity of the cumulative disparity.      Alternately, the complement of the candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of the first polarity. In a high-transition mode of operation, the bits within data blocks including fewer than a minimum number of logical 'I' signals ate selectively complemented so that each such selectively complemented data block includes in excess of the minimum number of logical transitions. In a low-transition mode of operation, the bits within data blocks having more than a predefined number of logical 'I' signals are selectively complimented so that each such selectively complemented data block includes less than the maximum number of logical transitions.

Granted: 2011-02-15
Abstract: Disclosed are methods of inducing or modelling the pathological state of an aggregating disease protein (ADP - e.g. tau protein) which is associated with a disease state in which the ADP aggregates pathologically (e.g. Alzheimer's disease) through an induced conformational polymerisation interaction, the method being characterised by the step of providing a membrane-localisable fusion protein comprising (i) an aggregating portion, which is derived from the ADP, or from a protein which initiates pathological aggregation of the ADP, (ii) a heterologous membrane-localising portion. Membrane-localisation of the ADP-based fusion protein is believed to cause the high-affinity capture site of the ADP protein to become exposed such that aggregation of further ADP, which may be native or heterologous to the system, to be promoted. The method can be carried out in vitro, or in cell- and animal-models, and may be used to screen for modulators of the aggregation process by monitoring aggregation e.g. by monitoring the production of the ADP-related degradation products resulting from the aggregation. Also provided are materials, processes for use in or with the methods.
