Filed: 1998-12-14
Abstract: The telecommunications system comprises an interface mechanism for passing signalling events over a communications link between modules of the telecommunications system separated by the communications link. The interface mechanism comprises a network-side oject on the telecommunications network side of the communications link for receiving a first signalling event from a first module of the telecommunications system and for generating a first signalling message to represent the first signalling event, and a user-side object on the subscriber terminal side of the communications link for receiving a second signalling event from a second module of the telecommunications system separated from said first module via the communications link, and for generating a second signalling message to represent the second signalling event. Further, the network-side object is arranged to pass the first signalling message to the user-side object over the communication link for subsequent processing by modules on the subscriber terminal side of the communications link, and the user-side object is arranged to pass the second signalling message to the network-side object over the communications link for subsequent processing by modules on the telecommunications network side of the communications link. By this approach, a flexible interface mechanism is provided for handling signalling information that needs to be routed between modules of the telecommunications system.

Title: Method of producing hard protective coatings on aluminium alloy items
Inventor: SHATROV ALEXANDR SERGEEVICH
IPC: C25D11/06
Filed: 1997-12-17
Abstract: The present invention pertains to the field of electrolytic and plasmic oxidation of aluminium alloys. This invention more precisely relates to a method that comprises carrying out an anodic-cathodic oxidation in an alkaline electrolyte at a temperature of between 15 and 50 ~C using an alternative current having a frequency ranging from 50 to 60 Hz. During the process initial stage and for a duration of between 5 and 90 seconds, the oxidation is carried out at a current density of between 160 and 180 A/dm2, after which the current density is lowered down to a range of between 3 and 30 A/dm2. The process is carried out according to a mode of spontaneous decrease in the power used and without any adjustment of said mode by an operator until a coating of a desired thickness is obtained. This method uses as an alkaline electrolyte an aqueous solution containing from 1 to 5 g/l of an alkaline metal hydroxide, from 2 to 15 g/l of an alkaline metal silicate, from 2 to 20 g/l of an alkaline metal pyrophosphate and from 2 to 7 g/l of peroxide compounds with a 30 % H2O2 conversion. This method is used for improving the protection properties of oxide-ceramic coatings without additional power consumption and without temporary resources due to a better micro-hardness, a better density and a better adhesion force to the substrate.

Abstract: The present invention provides systems and methods for selectively applying electrical energy to a target location within a patient's body, particularly including tissue in the spine. The present invention applies high frequency (RF) electrical energy to one or more electrode terminals (58) in the presence of electrically conductive fluid (50) to remove, contract or otherwise modify the structure of tissue structures. In one aspect of the invention, a method is provided for treating herniated discs within a patient's spine by applying sufficient electrical energy to the disc tissue to reduce a volume of the disc, thereby relieving pressure on a spinal nerve. In one embodiment, the high frequency voltage is sufficient to ablate a portion of the nucleus pulposis, either the extruded portion outside of the annulus or a portion or all of the pulposis within the annulus. In another embodiment, the electrode terminal is advanced into the annulus and sufficient high frequency voltage is applied to contract or shrink the collagen fibers within the nucleus pulposis.  This causes the pulposis to shrink and with draw from its impingement on the spinal nerve.

Title: Method and apparatus for the management of data files
Inventor: BESSETTE LUC
IPC: G06F17/30
Filed: 2000-12-22
Abstract: The present invention provides a network system for storage of medical records. The records are stored in a database on a server. Each record includes two main parts, namely a collection of data elements containing information of medical nature for the certain individual, and a plurality of pointers providing addresses or remote locations where reside other medical data for that particular individual. Each record also includes a data element indicative of the basic type of medical data found at the location pointed to by a particular pointer. This arrangement permits a client workstation to download the record along with the set of pointers which link the client to the remotely stored files. The identification of the basic type of information that each pointer points to allows the physician to select the ones of interest and thus avoid downloading massive amounts of data where only part of that data is needed at that time. In addition, this record structure allows statistical queries to be effected without the necessity of accessing the data behind the pointers. For instance, a query ran be built based on keys, one of which is the type of data that a pointer points to. The query can thus be performed solely on the basis of the pointers and the remaining information held in the record.

Inventor: CHASE LEE
IPC: D21F7/00
Filed: 1999-04-12
Abstract: An array of sensors that are positioned underneath the wire of a paper making machine are employed to measure the conductivity of an aqueous wet stock.  Conductivity of the wet stock is directly proportional to the total water weight within the wet stock; consequently, the sensor provides information used to monitor and control quality of paper sheet produced. CD water weight profile is obtained practically instantaneously and the MD and CD variations are essentially decoupled.  Quality improvements to the sheet fabricated are achieved by providing fast control of the actuators and by tuning components to eliminate sources of variations. Dry stock weight of wet stock sheet resting on a water permeable moving wire can be measured employing a water weight sensor element positioned adjacent to the wire generating signals indicative of water weight of the sheet. The moisture level CD profile of a sheet of material can also be measured.

Abstract: When charging at a voltage with a polarity different from that of a voltage charged in the capacitive display element, by turning the switch ON, after carrying out a charging/discharging to modulate both electrodes of the capacitive display element to the ground potential, the same is charged at a voltage with another polarity.  As compared with the case where the charging/discharging between the positive power supply voltage + V M and the negative power supply voltage - V M is made directly, the electric power consumption can be reduced to 1/2 when the same is once modulated to the ground potential 0V.  The electric power consumption can be further reduced by modulating the intermediate potential in a plurality of steps.

Title: Integration of solvent deasphalting, gasification, and hydrotreating
Inventor: WALLACE PAUL S
IPC: C10G49/22
Filed: 2000-01-11
Abstract: During the hydrotreating process, hydrogen sulfide and short chain hydrocarbons such as methane, ethane, propane, butane and pentane are formed. The separation of gas from hydrotreated liquid hydrocarbons is achieved using a stripper and a flash drum. High pressure steam or nitrogen is contacted with the hydrotreated liquid hydrocarbon material. This high pressure steam strips the volatiles, i.e., hydrogen, the volatile hydrocarbons, hydrogen sulfide, and the like, from the oil. The gaseous streams is then separated and cooled to remove condensables, including primarily water, short chain hydrocarbons, and hydrogen sulfide in the water. The condensables are advantageously sent to the gasifier, where the hydrocarbons are gasified, the water moderates the gasifier temperature and increases the yield of hydrogen, and where hydrogen sulfide is routed with the produced synthesis gas to the acid gas removal process.
