Patent number: 10449676Abstract: Determining deviation of a multi jointed robot under load using a tribological contact between an end of the robot and any available hard constraint near the robot, involves pressing the end against the constraint, and then soliciting a movement of the end relative to the constraint in a tribologically resisted direction to apply a force that does not overbear the resistance. By measuring the force and a position encoded by the robot, a deviation of the robot under the corresponding load is determined. Correction terms may be required for deformation of the tribological surface and/or constraint. The constraint may be tooling or parts subjected to an intended process. The deviation at many measurement poses of the robot, each in multiple resisted directions, within the ordinary operating space of the robot, was used to derive compliances of the robot, and a kinetostatic model.Type: GrantFiled: March 23, 2015Date of Patent: October 22, 2019Assignee: National Research Council of CanadaInventors: Bruno Monsarrat, Yves Fortin

Publication number: 20090226932Abstract: The present invention is directed to novel G protein-coupled receptors that are found predominantly in the dorsal root ganglia. The invention encompasses both the receptor proteins as well as nucleic acids encoding the proteins. In addition, the present invention is directed to methods and compositions which utilize the receptors.Type: ApplicationFiled: May 11, 2007Publication date: September 10, 2009Inventors: Sultan Ahmad, Denis Banville, Yves Fortin, Paola Lembo, Dajan O'Donnell, Shi-Hsiang Shen

Patent number: 7562692Abstract: A cast composite material is prepared by furnishing an aluminum-based matrix alloy and forming a mixture of free-flowing boron carbide particles and the aluminum-based matrix alloy in molten form which is stirred to wet the matrix alloy to the boron carbide particles and to distribute the particles throughout the volume of the melt. The molten mixture is then cast. The fluidity of the molten mixture is maintained by (a) maintaining the magnesium content of the matrix metal below about 0.2% by weight, or (b) starting with a matrix metal containing less than 0.2% by weight magnesium and adding further magnesium to the mixture a short time before casting, or (c) having at least 0.2% by weight titanium present in the mixture.Type: GrantFiled: October 24, 2003Date of Patent: July 21, 2009Assignee: Alcan International LimitedInventors: Jean-Yves Fortin, Jacques Sheehy, Camil Jean, Paul Brisson, Uta Harnisch, Don Allen Doutre, Xiao-Guang Chen

Patent number: 7550029Abstract: A method is described for reclaiming an Al—B4C composite scrap material. The method involves heating a liquid pool of molten aluminum while also pre-heating the scrap material. The scrap material is then added to the molten aluminum and a predetermined melt temperature is maintained in the liquid pool until all of the scrap material melts into the molten aluminum to form a resultant composite melt. Finally, the resultant composite melt is stirred to promote uniformity. A method is also described for preparing a B4C-containing aluminum cast composite products that involves preparing a mixture of free-flowing B4C particles and molten aluminum and stirring the mixture to wet the aluminum to the B4C particles. The mixture is then cast into a cast composite material and processed to form the cast composite product and Al—B4C composite scrap material. The scrap material is then reclaimed by the method described above.Type: GrantFiled: April 21, 2005Date of Patent: June 23, 2009Assignee: Alcan International LimitedInventors: Xiao-Guang Chen, Jean-Yves Fortin

Patent number: 5364443Abstract: A method of recovering an aluminum-containing metal from a scrap material containing the metal and an organic contaminant, such as paper, plastics, lacquer, paint or oil. The method involves creating a fluidized bed of solid particles, maintaining a zone of the bed at a temperature in the range of the melting point of the metal to 1000.degree. C., introducing the scrap material into the fluidized zone to cause decoating of the metal within a time in the range of 1 to 40 seconds, at least partially melting the metal, and removing the metal material from the fluidized bed. In this way, decoating and at least partial melting is achieved essentially at the same time for improved efficiency. Metals of different melting point may also be separated from each other by providing a series of temperature zones in the fluidized bed (or in a series of fluidized beds) of progressively increasing temperature.Type: GrantFiled: December 1, 1993Date of Patent: November 15, 1994Assignee: Alcan International LimitedInventors: Francois Tremblay, Gilles R.
