Patent number: 6086824Abstract: An automatic sample testing machine for testing samples stored in test cards. The machine has a test sample positioning system for moving a tray containing a plurality of test sample cards and fluid receptacles among various stations in the machine. The machine has a diluting station for adding a predetermined quantity of diluent to the receptacles as needed. A pipetting station transfers fluid from one receptacle to another. A vacuum station is provided having a vacuum chamber moveable relative to the tray between upper and lower positions. The chamber cooperates with the tray to make a sealing engagement with the top surface of the tray when it is lowered to the lower position. A vacuum generator supplies vacuum to the chamber. When the vacuum is released from the chamber, the fluid samples are loaded into the cards from the receptacles.Type: GrantFiled: June 7, 1999Date of Patent: July 11, 2000Assignee: bioMerieux, Inc.Inventors: Mark Joseph Fanning, Jean-Pierre Bernard Gayral, Roger James Morris, Ron Robinson, William Ernest Seaton, David B.

Patent number: 5900519Abstract: A catalytic process is described for the selective alkylation of a polycyclic aromatic compound comprising reacting the polycyclic aromatic compound with an alkylating agent in the presence of a catalyst to thereby yield the desired alkyl substituted polycyclic aromatic compound with improved selectivity and improved yield. The process is particularly suitable for the selective dialkylation of polycyclic aromatic compounds in the para-, respectively beta-positions. The catalyst is a protonic form of a mordenite having an atomic Si/Al ratio of at least 5:1, comprising additional metal species in a molar ratio metal (in the metal species)/aluminium of at least 0.10 and having a biphenyl sorption of at least 0.05 g biphenyl per g of catalyst.Type: GrantFiled: October 28, 1996Date of Patent: May 4, 1999Assignee: Solutia Inc.Inventors: Patrick Pierre Bernard Notte, Georges Marie Joseph Luc Poncelet, Marc Joseph Henri Remy, Pierre Fernand Marcel Ghislain Lapdinois, Marina Jeanne Madeleine Van Hoecke

Patent number: 5853667Abstract: A positioning system for a sample testing machine incudes a base pan and a set of independent drive systems for sliding a sample tray across the base pan. Each of the drive systems incudes a paddle that engages a side of the sample tray. The paddle is slideably mounted to a shaft with a collar that slides over the shaft. A motor and drive belt is provided to move the collar along the shaft, causing the paddle to engage the side of the sample tray and slide the sample tray across the base pan. Track sections are provided in the base pan to prevent the sample tray from rotating as the paddle slides the sample tray across the base pan.Type: GrantFiled: September 22, 1997Date of Patent: December 29, 1998Assignee: bioMerieux Vitek, Inc.Inventors: William Ernest Seaton, Mark Joseph Fanning, Craig Drager, Ron Robinson, Roger James Morris, Jean-Pierre Bernard Gayral, JoAnne T.

Patent number: 5808304Abstract: The most common method of determining whether a breast contains cancerous tissue utilizes ionizing radiation, i.e. x-rays, which possible have tissue damaging properties. It has been found that lasers can be used as a light source in a breast tissue transillumination process. However, due to the high scattering coefficient (or diffusing properties) of breast tissue, it is not possible to obtain images having good resolution using classical transillumination techniques, even when a laser is used as the light source. When passing through a diffusing medium, a laser pulse decomposes into three classes of photons, namely ballistic, snake-like and diffuse photons. In most practical situations, the ballistic photon portion of a laser pulse, which travels in a straight line, does not pass through the tissue, i.e. only snake-like and diffuse photons pass through the tissue.Type: GrantFiled: November 18, 1996Date of Patent: September 15, 1998Assignee: Aerospace Research Technologies, Inc.Inventors: Andre Parent, Pierre Bernard, Pierre Galarneau

Patent number: 5245116Abstract: A process for the treatment of spent pot linings impregnated with alkali metal cyanide and fluoric products by grinding previously crushed pot linings in the presence of lime, suspending the ground pot linings in an aqueous medium in order to precipitate a flux in the form of CaF.sub.2 accompanied by the release of soda, followed by the heating of the suspension at a temperature T>140.degree. C. in the presence of clay to form, after fixing the free soda, insoluble synthetic silicate compounds of the feldspathoid or zeolite type and finally the separation by filtration of the resulting solid phase from the liquid phase, which liquid phase is recycled to form a new ground pot lining suspension.Type: GrantFiled: November 18, 1991Date of Patent: September 14, 1993Assignee: Aluminium PechineyInventors: Jean-Claude Bontron, Pierre-Bernard Personnet, Jean-Michel Lamerant

Patent number: 4702820Abstract: Process for pretreatment at atmospheric pressure or a pressure close to atmospheric pressure by alkaline wetting and holding at temperature of natural materials whose gangue comprises argillaceous compounds capable of forming a stable plastic suspension in the presence of water and containing at least one combustible element which can be put into useful form wherein, in order to permit subsequent easy operations for separation of the liquid aqueous and solid phases of the gangue:(a) the natural material which was possibly been subjected to a preliminary drying operation is brought into intimate contact with at least 4 kg expressed in terms of OH.sup.- of at least one alkaline agent per ton of clay contained in said material, the total volume of liquid present in the natural material after the contacting operation being such that the ratio L/S of said volume expressed in terms of cubic meters to the weight of solid expressed in tons of dry ore is at most equal to 0.Type: GrantFiled: August 8, 1986Date of Patent: October 27, 1987Assignee: Uranium PechineyInventors: Pierre-Bernard Personnet, Jean-Michel Philbert

Patent number: 4613361Abstract: A process for pretreatment at high temperature by means of an aqueous pretreatment solution, of crushed ores containing at least one usable metal element, whose gangue contains argillaceous compounds which, in the attack operation for making use of the ore, are capable of forming a stable plastic suspension in the presence of water, which makes it virtually impossible subsequently to separate the liquid and solid phases by virtue of its character being such that it cannot be subjected to filtration and/or settlement, which is characterized in that, to cause stabilization of the argillaceous gangue before the operation of subjecting the ore to attack and to produce easy separation of the liquid and solid phases after the attack operation, the ore, the granulometry of which is at most equal to the liberation sieve mesh size of the metal or metals to be put to use, and before being subjected to the attack operation for making use of the ore, is brought into contact with an aqueous pretreatment solution containinType: GrantFiled: November 28, 1984Date of Patent: September 23, 1986Assignee: Uranium PechineyInventors: Jean-Michel Lamerant, Francois Pallez, Pierre-Bernard Personnet

Patent number: 4470824Abstract: The pulley of moulded plastics material is mounted adjacent to the outer side of the bicycle wheel flange, concentrically with this flange. The pulley comprises a grooved ring around which extends a belt for driving a distance recorder. From the periphery of the ring, on the side of the latter adjacent to the wheel flange, extend in generally radial directions are three arms which are angularly spaced 120.degree. apart. Mounted on the free end portion of the arms by means of a pivot pin are the end portions of tabs which are provided with a mounting device at the opposite end. This mounting device is adapted to engage with a wheel spoke so as to maintain the pulley in a centered position relative to the wheel flange.Type: GrantFiled: March 8, 1982Date of Patent: September 11, 1984Assignee: Huret et ses FilsInventors: Roger Huret, deceased, by Alain Pierre Bernard Huret, legal representative
