Title: Method for the insolubilisation and consolidation of used brasques from hall-heroult electrolyte vessels
Inventor: BOUZAT GILBERT
IPC: B09B3/00
Filed: 1997-11-25
Granted: 2007-05-15
Abstract: The invention concerns a method for the insolubilisation and consolidation in the form of pellets of used brasques from electrolyte vessels for producing aluminium comprising the grinding of said brasques and mixing them closely with various refractory pulverulent additives before burning characterised in that it consists in: introducing a first additive selected from the group of aluminium silicates for fixing the alkaline metals during burning; introducing a second additive which, during burning, will combine with the saturating fluorine-containing compounds to form new stable and insoluble compounds and by its non-combined supernatant fraction, will ensure the consolidation of the mixture, and this additive is selected from the group of calcium oxides and salts and preferably of lime cements and mortars; carrying out a forming by agglomerating in the form of pellets the close mixture of used ground brasques with said first and second pulverulent additives before burning at a temperature between 700  DEG C and 950  DEG C.

Title: Method, system and data structures for computer software application development and execution
Inventor: MCGUIRK FRED
IPC: G06F9/46
Filed: 1997-12-12
Granted: 2009-06-02
Abstract: A method, system and data structures for software development and execution includes a Run Time Event Manager and a set of Models. A Model is a type of data structure that contains no code but an ordered set of references to other Models, to Methods, or other Objects. Models are made accessible to the Run Time Event Manager by registering them upon satisfaction of a set of conditions. In one embodiment of the invention, the Run Time Events Manager is a fetch-execute loop implemented in code that, upon each loop, operates upon one of a set of Models, checks external I/O conditions and, subject to such conditions, may process different or Variant Models, rather than standard or Paradigm Models associated with default conditions.  Also, an Elastic Database may be implemented according to the invention that permits dynamically extensible database functionality.

The antioxidant material is from the group containing nickel, chromium, gold, or an alloy of these metals. The deoxidation is by treating the chips with nitric acid. The plate (20) has an opening for the passage of the gate electrode and the interposition of an insulating material in the formation of the emitter electrodes. In the formation of the emitter electrodes, the gate electrode is formed, and also a supply track insulated from the rest of the chip. The plate (20) is made of anodized metal, e.g. aluminum, and gate electrode production comprises forming a conducting layer by metallization of the anodized plot surface, forming the supply track by metallization of the anodized chip surface, and deposition of a layer of the antioxidant material on the plots. The supply track after formation is covered with a metallic layer. The covering of the metallized track is done by anodizing.

Title: Liquid filter with centrifugal separator
Inventor: WONG JOHNNY
IPC: B01D35/22
Filed: 2000-09-08
Granted: 2009-08-04
Abstract: A filter cartridge which removes particulate contaminants from liquids includes an annular filter element which, for example, may be a pleated paper filter element, as well as an array of fins which impart a spiral motion to the liquid prior to the liquid passing through the filter element. The spiral motion imparts a centrifugal force to the particulate contaminants causing heavier filter contaminants to move away from the filter media to proximity with the wall of a housing enclosing the filter media and to subsequently accumulate in an axial space disposed beneath the filter media. Since the filter media does not need to remove particles already precipitated out of the liquid, the life of the filter media is extended, the capacity of the filter media is increased, and the distribution of contaminant particles over the upstream side of the filter media is made more uniform.

Abstract: In a mobile communication system, when a mobile visitor terminal registered at a first network enters a second network, it sends a registration signal to a first exchange belonging to the second network. The first exchange sends a roaming start request signal to the first network. On receiving authentication information from the first network, the exchange writes it in a VLR (Visitor Location Register) storage. On the origination of a call on the visitor terminal, call information is written to a call information storage. A third exchange stores in a VLR holding node number storage the fact that the call information is stored in the first exchange. when the visitor terminal moves to the area of a second exchange, the second exchange sees, based on the content of the VLR holding nude number storage, that the authentication information is stored in the first exchange, and obtains it. The second exchange switches connection thereto on the basis of the authentication information and call information.

Abstract: Disclosed is a method for obtaining a precise detected value of a similarity between voices or the like. Standard and input pattern matrices, each having a voice feature amount as a component, are prepared (S1 and S2). A reference shape having a variance different for each specified component of the pattern matrices is prepared, and positive and negative reference pattern vectors, each having a value of the reference shape as a component, are prepared. Then, while the specified component (a center of the reference shape) being made to move to each component position j1=1 to m1, j2=1 to m2 of the standard pattern matrix, a shape change between the standard and input pattern matrices is substituted for shape changes of the positive and negative reference pattern vectors. And, an amount of change in kurtosis of each reference pattern vector is numerically evaluated to obtain a shape change amount Dj1j2 (S3). Then, a value of a geometric distance between the pattern matrices is calculated from Dj1j2 (S4).
