Abstract: A device for real-time correction of set-point signals intended to receive at the input set-point signals and to deliver at its output set-point signals that are modified to compensate for defects, negative effects or the like subsequently encountered during the processing and/or the application of the set-point signals. This device (1) includes at least one circuit (1?) that is based on a microprogrammed structure and composed of several subassemblies (3, 4, 5, 6, 6?) that work with digital components essentially including a micro-sequencer (3) forming a counter, a memory (4) for storing micro-instructions, and a processing unit (5) combined with at least one working memory (6, 6?) and integrating arithmetic calculation modules (7,7?), whereby the processing unit (5) modifies the data of set-point signals in accordance with the micro-instructions that are addressed by the micro-sequencer (3) and by taking into account the correction coefficients that are provided.

Abstract: The invention concerns a method for analysing the intracellular chemical state of living cells by nuclear magnetic resonance (NMR). Said method comprises a step which consists in preparing the cell sample and a step which consists in an NMR analysis of the sample, both steps being carried out at very low temperature so as to freeze the biochemical state of the living cells to obtain specific and accurate reproducible measurements of the cellular functioning in given conditions. The invention also concerns the device coupled to the NMR spectrometer for implementing the method of analysis.

Abstract: An L-C type filter module comprising at least two capacitors and at least one inductor. Each of the capacitors consists of a first elongated element made of conductive material partially fitted in a hole made in a second element made of conductive material, connected electrically to the second elements of the other capacitor(s) or possibly common to the various capacitors, at least the internal lateral surfaces defining the holes being covered with dielectric material, as are the edges of the openings of the holes or perforations and at least parts, or preferably all, of the external surfaces of the second element(s) adjoining the edges, and the coil of each inductor is carried by a support body made of dielectric material, possibly contiguous with the second element(s) or the dielectric coating at least partially covering the external face of each second element.

Abstract: A variable capacitor includes a first component made of conductive material in the form of an at least partially hollow rod, comprising a hole or perforation extending axially into the body of the first component to form a tube portion, and a second component also made of conductive material in the form of a rod able to be fitted to a variable depth into the axial hole, the engagement depth of the second component in the first component determining the degree of capacitive coupling between them and therefore the value of the resulting capacitor. The capacitor tube portion is provided on its internal face, preferably substantially over the whole depth of the axial hole, with a layer of dielectric material, the latter extending in a continuous manner over the edge defining the access aperture of the hole and onto an adjacent part of the external face of the tube portion.

Abstract: The object of the present invention is a variable capacitor comprising on the one hand a first component made of conductive material in the form of an at least partially hollow rod, comprising a hole or perforation extending axially into the body of said first component to form a tube portion and, on the other hand, a second component also made of conductive material in the form of a rod able to be fitted to a variable depth into said axial hole, the engagement depth of the second component in the first component determining the degree of capacitive coupling between them and therefore the value of the resulting capacitor.
