Abstract: Procédé de mesure de la différence de couleur du contenu de deux échantillons (1, 2) ou de deux zones de composants d'un échantillon, par l'utilisation d'une ou plusieurs sources de lumière (3 à 6) ainsi que d'un détecteur de lumière (7). Selon l'invention, les deux échantillons (1, 2), ou les zones de composants d'un échantillon, sont éclairés simultanément et, des deux échantillons (1, 2) ou zones de composants d'un échantillon, la lumière est envoyée simultanément vers le détecteur de lumière (7). Les rayons lumineux à mesurer émis par les échantillons (1, 2) ou zones de composants d'un échantillon sont de couleurs différentes, comparés entre eux, de sorte que le rayon lumineux à mesurer provenant du premier échantillon ou zone de composants est absorbé faiblement dans l'agent de coloration et le rayon lumineux à mesurer provenant du deuxième échantillon ou zone de composants est absorbé fortement dans l'agent de coloration. Les couleurs des rayons lumineux à mesurer provenant des échantillons (1, 2) ou zones de composants d'un échantillon sont alternées entre elles à une fréquence appropriée, par exemple à une fréquence comprise entre 1 c/s et 10000 c/s. Le signal à courant alternatif produit par le détecteur de lumière (7) est utilisé comme mesure de la différence de couleur des contenus des échantillons (1, 2) ou zones de composants d'un échantillon.

Abstract: In an infrared detector, a shutter is employed in an elastic wave element of a feedback type of oscillator containing the elastic element so that it emits infrared light intermittently. The period during which the peak of the oscillation output waveform from the oscillator exceeds a predetermined value is set to be the opening or closing time of the shutter, the number of clock pulses from a clock signal generator is counted during the time the shutter is opening or closing, and the difference between the counted values is obtained, thereby detecting the energy of the infrared light. This detector features not only an extremely high sensitivity, but a high detection accuracy, as well as the production of a digital output.

Patent EP-0144437-B1 (EP)
IPC: G01N11/10
Filed: 1984-05-14
Granted: 1988-08-10
Abstract: The invention relates to a moving-piece type of rheometer. In conventional moving-piece rheometers, a movable piece of a sensing member is supported by a mechanical structure, or no means for positional control is provided. In consequence, a conventional rheometer has a complicated mechanism, it is difficult to measure a very small sample therewith, and it is not possible to measure high frequencies therewith. A conventional rheometer cannot be hermetically sealed into a sample container, and the position of the sensing member is not fixed and therefore could sink or surface during measurement. The rheometer of the present invention solves these problems and can measure a fluid or viscoelastic substance which moves relative to the sensing member, by a control of the sensing member to a desired position or a movement in a non-contact manner, using magnetic force, not through a mechanical support structure but through a servo mechanism. This rheometer is useful in fields such as biorheological and rheological studies, and in the examination, use and manufacture of viscoelastic substances.

Title: Appareil et procede de congelation par distillation humide et seche pour la separation de melanges
IPC: B01D9/00
Filed: 1985-05-21
Granted: 1989-04-12
Abstract: Le procédé de congélation distillatoire est un procédé qui permet d'économiser de l'énergie lors de la séparation de mélanges et de la surépuration de produits chimiques. Le procédé de congélation par distillation humide et sèche représente une amélioration importante de la technique de congélation distillatoire et a considérablement élargi son champ d'application; la température et la pression de séchage sont sensiblement supérieures à celles du procédé directement sec correspondant, et une proportion importante d'impuretés à volatilité réduite dans la substance d'alimentation peut également être éliminée. Le procédé fondamental de congélation distillatoire humide et sèche comprend (a) une première étape de transformation d'un mélange liquide d'alimentation en un premier mélange solide-liquide, appelé mélange K1, (b) une deuxième étape de lavage du mélange K1 avec un liquide de lavage, de façon à former un deuxième mélange solide-liquide, appelé mélange K2, et un liquide L2 impur, et (c) une troisième étape d'exposition du mélange K2 à une opération de congélation distillatoire sèche de façon à former une masse de phase solide épurée, appelée S3, et une vapeur à basse pression V3. Divers liquides de lavage peuvent être utilisés pendant l'étape de lavage des cristaux. Il est important de noter qu'il n'est pas nécessaire que le liquide de lavage soit pur, et qu'il peut contenir quelques impuretés volatiles, étant donné que les impuretés volatiles dans le liquide de lavage seront absorbées par le mélange K2 et éliminées pendant l'étape de congélation distillatoire sèche. Le procédé de congélation distillatoire à solide recyclé est une autre version du procédé dans laquelle le mélange K2 est formé en mélangeant la substance d'alimentation avec une masse de solide recyclé et en soumettant le mélange K2 à une opération de congelation distillatoire sèche.

Abstract: A method and apparatus for extracting character information from a signal matrix of gray level pixels, including an annular ring binarizer (30) and an adaptive post-thresholder (40). In the binarizer (30), pixels located in a pair of concentric annular rings (R5, R7) around a pixel of interest are compared to determine if a pair of relatively dark pixels occur in neighboring positions in the two annular rings (R5, R7) and if so determining the pixel of interest to be black. A binarized matrix (BI) formed in this manner is combined with the original gray level matrix to form an extracted matrix image (EI) which is used by the post-thresholder (40) to form a histogram. The histogram is analyzed to provide a post-threshold value for each document read, utilized to produce, from the extracted matrix image (EI), an improved two-level output image (PI).
