  • Publication number: 20180057023
    Abstract: An air handling system (1) for a land transport vehicle, in particular a railway vehicle (M) is disclosed. The system includes: one or more air handling units (2) distributed within the vehicle (M); a cooling machine (4) that supplies frigories to the air handling units; and a frigories storage unit (8) that is capable of being loaded by the cooling machine and of supplying frigories to the air handling units when the vehicle is travelling in an enclosed or partially enclosed space. When the vehicle (M) is travelling in the open air, the cooling machine (4) supplies frigories to the air handling units (2) and loads the frigories storage unit (8) if a surplus of frigories is produced, by discharging into the exterior of the vehicle (M) the heat extracted from an interior volume of the vehicle.

  • Patent number: 6193177
    Abstract: A grinding apparatus for forward feeding material in a drum in which the grinding apparatus has a circular grinding track therein. The drum is driven in rotation at a speed such that material therein is held on the circular grinding track by centrifugal force. A knife is positioned in an upper descending portion of the drum for detaching material from the circular grinding track. A deflecting plate is disposed beneath the knife so as to receive materials detached by the knife and to divert the detached materials toward the output of the drum. The knife is disposed such that the knife has an active face forming an angle of between +15° and −50° with a radial plane extending between a horizontal axis of the drum and an edge of the active face.

  • Patent number: 6138933
    Abstract: A grinder having an annular track with a horizontal axis (14), a roller (16) capable of travelling over the track, a mechanism for pressing the roller against the track and means (18) for displacing the material from one edge of the track to the other in such a way that it passes several times beneath the roller before being evacuated. To enhance the efficiency of the grinder and the distribution of mechanical stresses in the roller and the track, the track (14) and the roller (16) are designed in such a way that the gap between them decreases from the edge of the track (14) located on the side for supplying the material to be ground to a distance from this edge at least equal to 80% of the width of the track, and in that this interval then swiftly increases to form a decompression area (19) on the ground material evacuation side.

  • Patent number: 5425273
    Abstract: A pressure sensor for connection to a transmission optical fiber which allows the transmission of a light beam. The pressure sensor comprises a material which is essentially elastic to deformation and optically transparent to the wavelengths of light used. The material includes at least two inclusions, each comprising an optical fiber segment. The distance between the inclusions varies when a deformation is exerted on the pressure sensor. This, in turn, modifies the focal length of the optical system defined thereby, and leads to a variation of the light energy collected by a transmissive optical fiber. The pressure sensor is suitable for detectors or measuring devices for medical use, and in this regard, a method for measuring blood or respiratory pressure is also provided.

  • Patent number: 4490609
    Abstract: The invention relates to a method of measuring the absorption of a photon flux in the fluid flowing in an oil well, for the purpose of determining the composition of the fluid. The invention also relates to a logging sonde for implementing such method.The photon flux produced by a source such as an X-ray generator irradiates the entire volume of fluid surrounding the sonde, and the energy of the photons is lower than a predetermined value, preferably 100 kev, so that the walls of the well are capable of substantially absorbing the photons impinging thereon. The photon flux includes an energy level at which photoelectric absorption is significant and another energy level at which Thomson scattering is predominant. Measurements of the photoelectric absorption coefficient and density are used to determine water, oil, and salinity.

  • Patent number: 4235278
    Abstract: The invention concerns an improvement in the casting ring which is provided on the periphery of the wheel in continuous casting machines. This ring is characterized in that its entire internal surface is in contact with the cast metal in the region of solidification, it is mounted completely freely on its support means, and it has a thickness in the vicinity of 1 mm. These characteristics enable it to be deformed when hot into a shape which is similar to its cold profile. This gives rise to the possibility of controlling the solidification of ingots and the aptitude for withdrawing the ingots without surface defects at a temperature higher than that obtained by the customary machines.
