Patent FR-2642549-A1 (FR)
Inventor: MEYER JACQUES
IPC: G01D5/26
Filed: 1989-01-27
Abstract: The sources (5) are powered sequentially. Following conversion to an electrical signal, each of the successive light signals coming from a source (5) is compared with two predetermined limit values. The operating condition of each of the sources and of each of the optical surveillance means are determined as a function of the results of the comparisons. The amplitude of the electrical signal corresponding to the output signal obtained successively for each of the sensors (20) is compared with a reference signal. The generator of electrical current (1) is controlled successively as a function of the result of comparing the electrical signal corresponding to the output signal from each of the sensors (5) with the reference signal, in such a way as to make the amplitudes of the compared signals equal. The condition of the surveyed parameter is determined by comparing the signal from the optical source, following transformation to an electrical signal, with two specified values.

Title: Method of optimising a classifier
Inventor: VALLET FRANCOIS
IPC: G06N20/00
Filed: 1989-03-14
Abstract: The present invention relates to a method of optimising a classifier into n classes. The method consists: - during a learning phase, in configuring a classifier which converts an input [Ai] of the learning base, belonging to the ki-th class into a vector-code ¦ ai > corresponding as closely as possible to an ideal vector-code ¦dki > in which the variable at the ki-th place is coded by a specific value, the other variables being coded by a single value different from the specific value, and - during a test phase, called generalisation phase, in applying to the said classifier an input to be classified [Ci] to convert it into a vector-code ¦ ci >, then to associate with it, from relative differences of its coordinates, an ideal vector-code according to a predetermined law called generalised-max criterion. Moreover, during the two learning and generalisation phases, the vector-code ¦ ci > (c1, c2, c3) is converted systematically at the output of the classifier into a vector code ¦ c'i > (c1', c2', c3') with the aid of an affine transform T, such that: T¦dk > = ¦dk > and T¦x > NOTEQUAL alpha ¦1> + T¦y > with non-zero real alpha , ¦x > and ¦y >, two different vector-codes. The invention applies especially to adaptive systems and to neural networks.

Title: Method and device for checking the leaktightness of a container of elongate shape
Inventor: CHENEBAULT PIERRE
IPC: G21C17/07
Filed: 1989-05-11
Abstract: The invention relates to a method and device for checking the leaktightness of an elongate container. The container Cr is placed in a leaktight enclosure Eel containing a control gas G. A first external part I of the container and the control gas G surrounding it are heated to a temperature greater than the liquefication temperature of the gas, a second external part II not surrounded with gas and complementary to the first is heated to a temperature less than or equal to the liquefaction temperature of the control gas G in order to cause, in the event of a leaktightness fault and penetration of the control gas G into the container Cr, liquefication of the gas in the vicinity of the inner wall of the second external part II of the container. The wall of the second part II is subjected to a temperature variation corresponding to the heat released by the transition of the control gas G into the liquid phase. A measurement of the time variation of the temperature of the second external part II is made and a decision criterion of the presence or absence of a leaktightness fault is established. Application to the checking of leaktightness of neutron absorber (control) rods in the reactors of nuclear power stations or to containers for packaging chemical or pharmaceutical products.
Patent FR-2647259-A1 (FR)
Inventor: GALVES JEAN-PIERRE
IPC: H01J29/32
Filed: 1989-05-16
Abstract: The invention concerns display screens and in particular electron beam indexation display tubes. Conventionally, the screen comprises alternate red and blue bands of luminophores separated from one another by black bands (32) providing a clear boundary between the colours. According to the invention, it is proposed to use metal oxides (manganese, chromium, iron) for the black network; these oxides are preferably used as a substrate beneath a chromium reflecting layer (34). The result is both good colour separation and a screen which only slightly reflects the diffuse ambient light. The use of these oxides is, moveover, perfectly compatible with vacuum deposition methods and fine photogravure, making it possible to obtain better resolution than with conventional colour television screens (using shadow masks), which make use of graphite.

Title: Silo for bulk material with bar-type extractor
Inventor: CLAUDE COQUET
IPC: B65D88/54
Filed: 1990-04-10
Abstract: The silo comprises a storage unit (1), an extractor (2) for rendering the material fluid and for conveying it towards an outlet opening (141) in a predetermined direction, and two longitudinal inclined deflectors (41, 42). A third inclined deflector (43) situated above the rear of the extractor (2) is fixed on the lower part of the unit (1) and reduces by approximately 30% the power consumption of the extractor. A fourth inclined deflector (44) is situated above the front of the extractor (2) and overhangs the outlet opening (141) for material, which avoids any obstruction of the said opening. The deflectors (43, 44) prevent any packing of the material on the movable elements of the extractor when the latter is started up.
