Patent CA-2253940-A1 (CA)
Inventor: SCHROEDER JON M
IPC: H01L35/30
Filed: 1997-05-09
Abstract: A series of closely packed thermocouples formed into a torus (60) are held in compression against the Lorentz Force by a dielectrically insulated tie strap (61). High current circulates through the torus (60) due to reduced electrical path length effected by low-thermal-conductivity elements (64) and grooves (38) formed in hot and cold fins (66 and 65). Reduced heat transfer between hot and cold fins (66 and 65) generates higher circulating current.  Thermoelectric junctions formed between the hot and cold fins (66 and 65) and the low-thermal-conductivity elements (64) are preferably established by coated layer(s) (67) of dissimilar materials including bismuth, constantan, nickel, selenium, tellurium, silicon, germanium, antimony, nichrome, iron, cadmium, tungsten, gold, copper, zinc, and silver. Operating as a thermoelectric generator (40), electrical power may be drawn from the circulating electric current using either a vibrating mechanical switch (70), a Hall effect generator (140) or a Colpits oscillator (159).

Patent CA-2258743-A1 (CA)
Inventor: PAULING HANS JUERGEN
IPC: H01M2/36
Filed: 1997-06-16
Abstract: L'invention concerne une batterie qui, lors de la maintenance ou en cas de danger, peut être aisément et en toute sécurité convertie d'un état de fonctionnement à un état de repos non dangereux de manière à éviter un court-circuit. Pour y parvenir, un dispositif de vidange actionnable par commande permet de vidanger rapidement l'électrolyte, tous les processus de production d'énergie étant arrêtés après vidange de l'électrolyte. D'autre part, on a mis au point une batterie présentant ces caractéristiques, dans laquelle, en cas de danger, une substance désactivante est introduite dans l'électrolyte par l'intermédiaire d'une canalisation, ce qui arrête tous les processus électrolytiques de production de courant.

Title: Maintaining document state history
Inventor: HAMBURG MARK
IPC: G06F17/24
Filed: 1999-01-21
Abstract: Methods and apparatus embodying techniques useful in systems for creating and modifying documents. A state history of a document for storing document states is maintained; and, whenever an interesting operation has occurred, the state of the document is automatically captured as it exists after the operation. The captured state is added to the state history. In another aspect, the techniques identify for a user on a display device a set of states that the document has been in by operation of the system; and enable the user to designate any arbitrary one of the identified states for further operations. The techniques may provide both linear and non-linear history.

Abstract: A device and method for re-vascularizing my-ocardial tissue of the heart using a stent (8) are pro-vided. Multiple stents (8) are implanted into an area of hibernating myocardial tissue to permit blood to flow from the left ventricle directly into the tissue for re-vascularization. Various stent (8) embodiments are disclosed that simultaneously pierce and penetrate the tissue during delivery, and that are configured to re-sist migration out of the tissue once implanted.    Alter-natively, the stent (8) may be inserted into myocardial tissue over a piercing delivery device (104). The stents are preferably delivered through a steerable catheter (46) percutaneously inserted into the left ventricle, and con-figured to hold multiple stents (8). The stents (8) are pushed from the catheter directly into the myocardium sequentially.

Title: Method for forming a non-uniform interface adjacent ultra hard material
Inventor: KESHAVAN MADAPUSI K
IPC: E21B10/56
Filed: 1999-02-12
Abstract: A non-uniform interface is formed between a polycrystalline ultra hard material layer and a cemented tungsten carbide substrate, or a polycrystalline ultra hard material layer and a transition layer, or a transition layer and a substrate of a cutting element.  A first sheet made from an intermediate material is formed and embossed on one face forming a non-uniform pattern raised in relief on the face. The embossed sheet is placed on a face of a presintered substrate. An ultra hard material sheet is formed and embossed, forming a non-uniform face complementary to the non-uniform face on the sheet of intermediate material.  The ultra hard material sheet is placed over the intermediate material sheet so that the complementary faces are adjacent to each other. The assembly of substrate and sheets is sintered in a HPHT process. The sintering process causes the first sheet to become integral with the substrate and results in a substrate having a non-uniform cutting face onto which is bonded a polycrystalline ultra hard material layer. Embossed transition material sheets may be employed between the ultra hard material sheet and the first sheet to form transition layers with uniform or non-uniform interfaces.

Patent CA-2264464-A1 (CA)
Title: Prioritized transaction server allocation
Inventor: DONAGHUE NORMAN J JR
IPC: G06F9/50
Filed: 1999-03-05
Abstract: A facility for distributing transaction servers to process transactions of a number of different types is provided. The transaction types are organized into two or more priority levels ordered from highest to lowest. Each priority level has one or more transaction types. In the facility, a service level goal attribution system attributes a service level goal to each transaction type reflecting the level of service sought for transactions of the transaction type. An identification subsystem identifies transaction servers when they become available to process transactions. In response to each transaction server identified by the identification subsystem, a transaction server distribution subsystem assigns the identified transaction server to process a transaction of a type that needs an additional transaction server to meet its service level goal, and whose priority level is at least as high as that of any other transaction types that need an additional transaction server to meet its service level goal. When the assigned transaction servers complete processing of the transactions to which they are assigned, the identification subsystem reidentifies these transaction servers as again being available to process transactions.

Title: A method and a device for coding data sequences
Inventor: PASSAGGIO FILIPPO
IPC: H03M7/36
Filed: 1998-04-08
Abstract: In a method and a device for tranforming a stream of digital numbers, the correlation between successive numbers is utilized in order to obtain a new stream having a very low correlation between the numbers, whereby the sequence of numbers can be coded much more efficiently from a compression point of view. The numbers are for this purpose coded with the difference between a predicted number (s'(i)) and the actual number (s(i)) taking into account that the sequence does not need to be possible to decode in reverse order. The non-reversible codes can also be applied in lossy data compression schemes. Such schemes can change in accordance with the currently available bandwidth in order to obtain a graceful degradation and optimal bandwidth usage when the compressed data stream is transmitted over a channel having a time varying bandwidth. A general method and device for reversible coding are also provided.
