Date Nov. 30, 1989.A method of transmitting an audio signal wherein the audio signal is partitioned into successive (in time) blocks by means of time windows, the signal parts contained in the blocks are converted to short-time frequency spectrums by transformation, subsequently the short-time frequency spectrums are coded on the basis of psycho-acoustical masking laws and are transmitted. The received coded signals are decoded, the short-time frequency spectrum signals are brought back into the time domain through re-transformation, and finally the blocks present in the time domain are assembled. Moreover, the blocks are partitioned into sub-blocks and, in case of signal level changes from one block to the other which exceed a predetermined value, the signal parts in the sub-blocks are subjected to a compression prior to transformation and to a complementary expansion after the re-transformation. To improve the signal-to-noise ratio, the signal is amplified and/or attenuated in the sub-blocks during the compression dependent on the average signal powers in the respective sub-blocks.

Abstract: A method and apparatus for sorting articles with small density differences utilizing a flotation stream. A separator is provided in which a flotation stream continuously flows through a trough and is used to effect the separation of a mixture of articles having small density differences into several groups. Each density group of the mixture of articles to be separated is introduced at the head of the flotation stream at a selected depth. In one embodiment, the flotation stream may be comprised of a fluidized bed which is created by forcing a gas upwardly through a fluidization medium such as sand. In another embodiment of the invention, the flotation stream may be formed from a liquid. Once the mixture of articles is introduced at the selected depth into the flotation stream near the head of the stream, since the density of the flotation stream is greater than the density of the articles, the articles of lesser density begin to ascend toward the top of the flotation stream while at the same time the articles are carried downstream by virtue of the velocity of the flotation stream. Articles having a greater density will be carried further downstream whereas articles having less density will ascend to the top of the stream at a point further upstream, thereby effecting a spacial separation of the articles based on their differing densities.

Abstract: A method for determining the amount of an analyte in a sample fluid utilizes a multilayer assay element which comprises at least one reagent layer and a light-blocking layer. The assay method includes the steps of optically reading a signal producing species, e.g. a fluorescent label, a first time before the sample fluid is applied to the assay element and a second time, at the same wavelength and in the same location within the assay element, after the sample fluid has been applied to the assay element and the sample analyte has interacted with the reagent(s) present in the assay element. The ratio of the two signals is taken and compared with that for known amounts of the analyte to determine the amount of analyte in the sample fluid.

Abstract: L'invention a pour objet un procédé et un dispositif pour produire une table d'impression numérique pour les couleurs d'imprimerie dans les appareils de reproduction des images. A cet effet, on obtient des valeurs chromatiques par un balayage des originaux. On mesure les couleurs pures des trois couleurs d'imprimerie et du blanc. Ensuite, on détermine des couleurs-modèles qui ont une relation aussi linéaire que possible avec les couleurs d'mprimerie. On atteint cet objectif en disposant le domaine de chromaticité de l'échelle d'imprimerie de telle manière que les stimuli primaires de couleur des couleurs-modèles du diagramme de chromaticité se trouvent chacun sur un rayon des trajectoires des couleurs de l'échelle à travers le point blanc, le triangle établi entre les stimuli primaires de couleur englobant le domaine de chromaticité de l'échelle d'imprimerie. La graduation des stimuli primaires de couleur est adapté aux couleurs d'imprimerie selon une racine cubique. Le nombre des champs à balayer est déterminé au moyen des valeurs de mesure des diagonales dans l'espace. Il s'ensuit une interpolation spline cubique pour la production de la table d'impression.

Abstract: The process relates to the biological oxidation of pollutants to give CO2 and H2O in biofilters. The rate of degradation for paint-thinner mixtures of toluene, butyl acetate, xylene, white spirit and butanol can be increased to values above 150 g of organic substance per m<3> filter volume and hour, if granular material of porous hydrophilic substances is coated with activated charcoal (or adsorption resins). Microorganisms form colonies both in the pores of the hydrophilic granules and also on the outside of the granules (for example in compost, which partly fills the interstitial spaces of the granular packing). Control of the gas resistance of the filter layer is achieved by controlled spraying with aqueous liquids. Any pollutant content of the aqueous liquid is likewise supplied to the biological oxidation by this means.
