Patent CA-2343892-A1 (CA)
Inventor: PEDRETTI GIUSEPPE
IPC: B32B15/08
Filed: 1999-09-06
Abstract: A method is described for the manufacture of a Copper-Aluminium-Copper component (C-A-C "sandwich") which can be used in the production of multilayer printed circuit boards, obtained by means of joining two external sheets of copper to one internal sheet of aluminium by means of a process of electro-mechanical or mechanical joining, which does not require the use of additional material (such as, for example, an adhesive) and guarantees a consistently high level of quality. According to a first embodiment, the joining process, normally continuous, is based on the use of a sonotrode to effect ultrasonic welding, wherein a single ultrasonic weld provides two joining zones between the two external copper sheets and the one internal aluminium sheet.  Alternatively, the joining process is based on the exploitation of the plasticity of the materials under the action of knurling wheels in order to effect the joining of the various sheets. At last, according to a further embodiment, the component is manufactured with at least one layer of resin deposited externally on one of the external faces of the two copper sheets, which are not into contact with the internalaluminium sheet.

Title: Anticorps anti-facteur de von willebrand specifiques de conformation
Inventor: MCLEOD ANNE
IPC: A61K39/395
Filed: 1999-10-20
Abstract: L'invention concerne des anticorps et des fragments d'anticorps qui se fixent spécifiquement sur la conformation active du facteur de Von Willebrand humain. Les anticorps préférés sont des fragments constitués de la région variable à chaîne unique des immunoglobulines, produits par recombinaison. Du fait que lesdits anticorps ou fragments d'anticorps n'agissent qu'au niveau des sites de formation du thrombus et n'interfèrent pas avec l'activité normale des plaquettes circulantes, ils conviennent particulièrement bien comme antithrombotiques dans une large gamme d'applications.

Title: Method of water distribution and apparatus therefor
Inventor: WALKER ROBERT E
IPC: E03B7/10
Filed: 1999-09-29
Abstract: Water is supplied to a water user outlet facility (41, 42, 43) by maintaining a tappable flow of water in a recirculating loop that includes a pump (20) for establishing and maintaining the flow while imparting thermal energy to water, a water delivery path that extends from the pump to the outlet facility, a water return path that extends from the outlet facility back to the pump, and one or more water treatment devices (30, 31) for improving the potability of and imparting further thermal energy to water within said loop.      The flow is permitted to be controllably tapped at the facility by a water user while directing any untapped portion of the flow into the water return path. Such recirculation makes the recirculating loop and water within the loop less sensitive to the temperature of the surrounding environment and enables water distribution in freezing temperatures without a need for external heating,
Patent CA-2348864-A1 (CA)
Inventor: HAYES MARK A
IPC: G01N27/447
Filed: 1999-11-10
Abstract: A device for control of ultrasmall volume fluid flow used in the fields of electrophoretic separation, chemical analysis, and microchemical reactions has a substrate defining a capillary channel and integrated external electrodes to control electroosmotic flow. The channel geometry and integrated external electrode proximity reduce the voltage required for control of flow.  Longitudinal electrodes provide electrophoretic separation of components. High dielectric material between the integrated external electrode and capillary reduces the voltage required for the control of flow. Real-time flow monitoring and capillary channel surface coating enhance the control of flow.

Abstract: The invention relates to a method of separating substances according to which a substance containing at least a first and a second component are introduced, together with a wash fluid, into a container having at least one settling chamber and subjected to a gravitation field. Under the effect of the gravitation field the first substance component is concentrated in the settling chamber in a settling zone which is limited by a base. Next the substance containing said concentrated first component is evacuated from the settling zone through an opening in the base in the form of a sediment layer.  The wash fluid flows against the sediment layer from the side and then passes through said sediment layer such that the remaining second component is at least partly displaced from the sediment layer. The invention also relates to a device, notably for carrying out the above method.

Title: Method and apparatus for scalable probabilistic clustering using decision trees
Inventor: SAHAMI MEHRAN
IPC: G06F17/30
Filed: 2000-04-28
Abstract: Some embodiments of the invention include methods for identifying clusters in a database, data warehouse or data mart. The identified clusters can be meaningfully understood by a list of the attributes and corresponding values for each of the clusters. Some embodiments of the invention include a method for scalable probabilistic clustering using a decision tree. Some embodiments of the invention, perform linearly in the size of the set of data and only require a single access to the set of data. Some embodiments of the invention produce interpretable clusters that can be described in terms of a set of attributes and attribute values for that set of attributes. In some embodiments, the cluster can be interpreted by reading the attribute values and attributes on the path from the root node of the decision tree to the node of the decision tree corresponding to the cluster. In some embodiments, it is not necessary for there to be a domain specific distance function for the attributes. In some embodiments, a cluster is determined by identifying an attribute with the highest influence on the distribution of the other attributes. Each of the values assumed by the identified attribute corresponds to a cluster, and a node in the decision tree. In some embodiments, the CUBE operation is used to access the set of data a single time and the result is used to computer the influence and other calculations.

Patent CA-2389493-A1 (CA)
Inventor: MASINO MICHAEL D
IPC: E04G1/15
Filed: 2002-06-06
Abstract: Platform assemblies may be built up using a substantial number of inverted U-shaped vertical supports with platform hold down members that hold the platforms in place, thus avoiding slippage or pilferage. The hold down members form a unitary structure with the supports and platform assemblies to hold the platforms securely in place. The unitary structure of the scaffolding assembly with hold down members acts as a deterrent against pilferage of the platforms because the unitary structure does not allow the planks to be removed unless the platform assembly is substantially disassembled. It also reduces the steps required to assemble a secure platform assembly with hold down members thus saving time while still preventing slippage and pilferage. The hold down members have holes at one end, and these holes have a diameter slightly greater than the outer diameter (OD) of the guide pipes at the junctions between vertically extending pipes. The other end of the hold down member is substantially U-shaped and at least partially wraps around the platforms. As the scaffolding is erected, once the first, lower set of U-shaped supports and overlying planks are set in place, then the hold down members are mounted on the upwardly-extending guide pipes and across the planks. Then, when the next higher set of U-shaped supports is mounted onto the lower set, the hold down members are held in place between the two sets of pipes, and the planks are held in place.
