    Abstract: Method for locating the position of the wheels of a vehicle, each equipped with an electronic module for measuring operational parameters of each wheel, includes: controlling the transmission, by the module equipping that wheel, of n signals transmitted at times t1 to tn for given angular positions ?1 to ?n of the module, to a connected central processing unit, and to speed sensors each positioned close to a wheel, capable of delivering, values convertible into angular values, data representing the orientation of the wheel. The central processing unit is programmed to calculate, for each series of angular values ?1 to ?n provided by a wheel measuring sensor at the times t1 to tn, a characteristic value Vn1-Vnr representing the dispersion of the values ?1, (?2??2) . . .

  • Patent number: 9366629
    Abstract: Process for metering lead in a sample of original water, in which is placed a sample of the water of which at least a substantial portion of the colloidal and organic material is passed in solution (sample of pretreated water), having: a first stage, starting from a sample of pretreated water with an adjusted pH, the lead is concentrated and the other parasitic ions are at least partially eliminated to obtain a sample of water that is concentrated with lead and substantially lacking in other parasitic ions (sample of lead-concentrated water); and a second stage in which, starting from the sample of lead-concentrated water, the sample of lead-concentrated water is mixed with a selective, lead-sensitive fluorescent probe whose fluorescence intensity/lead metering function is known; then, the thus produced water/fluorescent probe mixture is excited by the light, and the fluorescence intensity of the thus excited water/fluorescent probe mixture is collected optically; finally, starting from the thus detected fluo

  • Patent number: 5350298
    Abstract: A canal instrument intended to be mounted on the head of a vibrating handpiece and allowing the application in the dental canal of filling paste by applying successive layers in order either to produce a complete filling or to produce a thin layer on the walls of the canal with a view toward lubrication or blocking-out of the spaces which can be left free by condensed gutta-percha points, including a handle (1) of known type for its fastening to the vibrating handpiece and a blade (2) provided over a part of its length, starting from its distal end, with one or more helicoid grooves whose edges (3) are rounded in order to prevent any cutting effect, and therefore reaming the root canal.

  • Patent number: 4559640
    Abstract: The invention relates to the polarization of a cathode of an X-ray tube by a high voltage cable comprising less conductors than the tube has polarization terminals. The missing voltages are processed by a device according to the invention, which comprises a voltage divider positioned between two of the voltages applied to the input terminals. It permits the use of standard long high voltage cables with limited stray capacitance without inducing dimensional control losses with respect to the tube foci.Application to multifocus X-ray sources.

  • Patent number: 4217517
    Abstract: An x-ray tube providing a flat, fan-shaped uniform x-ray beam.The tube includes inside a vacuum glass envelope, a cathode or cathodes, a fixed or cylindrical rotating anode, and an anti-divergence diaphragm. The anti-divergence diaphragm has an opening, through which passes the beam. The walls of the opening have the shape of a sector of the fan-shaped beam in one plane (z-z'), and are flat in a perpendicular plane. A plurality of x-ray absorbing blades are positioned in the opening parallel to the fan-shaped side dividing the opening and the beam passing therethrough, thereby minimizing overall divergence of the beam. A plurality of cathodes may be used in the rotating anode tube, each separately focusable to provide beams of different intensity, and alternately operable.
