Abstract: A method determines a volumetric power distribution of a core of a nuclear reactor using a set of detectors for measuring a neutronic flow provided outside the reactor vessel, and a set of probes for measuring the temperature of the coolant at the outlet of the fuel assemblies. The method comprises the step of determining a first volumetric power distribution using a neutronic calculation code instantaneously solving the diffusion equation and updating the isotopic balance of the core during the fuel depletion based on values of the core operation parameters, and the step of determining a new volumetric power distribution by adjusting the first volumetric power distribution using the measures provided by the sensors for measuring the neutronic flow and provided outside the reactor vessel and by the temperature measuring probes.

Abstract: The conversion device includes an input for receiving data corresponding to an image to be displayed. The received data is in a JPEG decoder output data format A processor is included for reconstructing and writing the image to be displayed into the image memory, in a display module expected input data format. The bandwidth of the image memory is greater than one byte. The processor is fully hardwired and includes a first logic stage for writing the received data byte by byte into an intermediate memory at chosen addresses such that the written data form a sequence of data in the display module expected input data format, and a second logic stage for reading the written data in the intermediate memory, forming successive packets of read data having a size corresponding to the bandwidth, and successively writing the packets into the image memory at chosen addresses such that the written packets together form all the lines of the image.

Abstract: An installation for measuring the pressure of at least one tire of a wheel of an aeroplane includes: at least a pressure measuring sensor associated with a tire; a unit operating on the pressure measurement provided in the aeroplane; and radio-frequency transmission elements including for the or each sensor, a revolving antenna borne by the wheel and connected to each measuring sensor and to a fixed antenna connected by a conductive cable to the unit operating on the pressure measurement. The fixed antenna is adapted to be borne by the aeroplane structure away from the or each wheel at least in an upper part of the shock strut of the landing gear bearing the wheel.

Abstract: A wheel assembly includes a wheel having a rim which is adapted to receive a tire. The wheel carries a sensor for measuring pressure inside the tire. The wheel is mounted so as to rotate around a spindle. In addition a communication device is located between the sensor and a device which is associated with the spindle for using measurements that are performed by the sensor. The communication device comprises a radio transmission device which includes a rotary antenna carried by the wheel and a fixed antenna that is carried by the spindle.

Abstract: The invention concerns and installation (12) for measuring the pressure of at least one tyre of a wheel (16, 24) of an aeroplane (10) comprising: at least a pressure measuring sensor (26) associated with a tyre; a unit (30) operating on the pressure measurement provided in the aeroplane (10); and radio-frequency transmission means including for the or each sensor, a revolving antenna (28) borne by the wheel (16, 24) and connected to each measuring sensor (26) and to a fixed antenna (34; 134) connected by a conductive cable (32) to the unit operating (30) on the pressure measurement. The fixed antenna (34; 134) is adapted to be borne by the aeroplane structure away from the or each wheel (16, 24) at least in an upper part of the shock strut (18, 20, 22) of the landing gear (14, 20) bearing the wheel.

Abstract: A wheel arrangement includes a wheel having a sensor for measuring pressure in the tyre; a spindle, about which the wheel is rotatably mounted with the aid of bearings around the spindle, and of communication elements between the sensor and elements for using measures, which are associated with the spindle. Communication elements are adapted to a transmission system with a frequency higher than 50 kHz comprising a rotating antenna which is supported by the wheel and a fixed antenna. The two antennae do not have their own rotational guiding element. The antennae are generally annular and disposed in a concentric manner on the same level around the wheel axis (X-X) of rotation, the average radial distance between the antennae exceeding 2 mm.

Abstract: The aldehydes, N-hexanal, 3-(Z)-hexen-1-al and 2-(E)-hexen-1-al, and their corresponding alcohols are enzymatically produced in high yield from linoleic, linolenic acid or a natural precursor thereof such as hydrolyzed oil. The acid or natural precursor is mixed with soy flour containing lipoxygenase which converts the acid to 13-hydroperoxy-octadeca-9,11-dienoic acid or 13-hydroperoxy-octadeca-9,11,15-trienoic acid. Guava homogenate containing lyase is added to convert the 13-hydroperoxy-octadeca-9,11-dienoic acid into n-hexanal or the 13-hydroperoxy-octadeca-9,11,15-trienoic acid into 3-(Z)-hexen-1-al. The n-hexanal or 3-(Z)-hexen-1-al is recovered, or reduced with yeast to n-hexanol or 3-(Z)-hexen-1-ol, respectively. Alternatively, the 3-(Z)-hexen-1-al is isomerized to obtain 2-(E)-hexen-1-al which is recovered or reduced with yeast to 2-(E)-hexen-1-ol which is recovered. The yeast used for reducing and isomerizing is Saccharomyces cerevisiae.
