Abstract: After grading of the ligneous part of hemp obtained by mechanical beating of hemp, it is impregnated with a calcium or barium salt in solution, preferably calcium chloride, a first bleeding of the impregnated ligneous part of hemp is then carried out by incorporating into the above solution pulverised hard bodies such as, for example, silica, lime or cement, with the exclusion of slag or alumina cements, a solution of sodium silicate is then sprayed onto the mixture obtained, which causes a petrification of the core of the ligneous part of hemp as well as a silicate treatment of its sheath and of the powdered hard bodies, finally a second quantity of pulverised hard bodies such as, for example, silica, lime or cement, with the exclusion of slag or alumina cements, is incorporated in the mixture containing the petrified ligneous part of hemp, and this results in a silicate-containing coating of the ligneous part of hemp, while causing the immediate bleeding of the said mixture, the constituents employed by the said process having suitable proportions relative to each other. The invention relates especially to the concrete produced from a charge at least partly incorporating the product obtained by application of the process according to the invention.

Abstract: Dans un transformateur de courant pour installation triphasée à trois conducteurs, on utilise, conformément à l'invention, un seul transformateur de traversée (4) monté côté courant triphasé. Grâce à ce dispositif, deux des trois conducteurs de phase sont traversés, soit avec le même nombre d'enroulements et des sens de traversée mutuellement opposés, soit avec le même sens de traversée et avec un nombre d'enroulements différent, dans un rapport de 2 pour 1, ou encore dans le même sens de traversée et avec un flux de courant divisé en deux parties dans un conducteur de phase, au moyen d'un shunt (15). Ces dispositifs permettent d'éviter l'apparition d'un flux résultant de valeur nulle. La tension secondaire de valeur double provoquée par une valeur double d'ampères-tours apparaissant deux fois à chaque période est divisée en deux par un montage de correction électronique. Ses ordres de commande sont dérivés d'impulsions de commande appropriées pour les thyristors (21-26) du montage en pont à courant continu (16). Deux montages en pont sont décrits. Le principal avantage réside dans l'économie importante réalisée pour le matériau du transformateur et, par voie de conséquence, sur l'encombrement.

Abstract: Une méthode améliorée pour déterminer statistiquement la présence de bruit sur un canal de communications de modulation de fréquence permet d'utiliser des techniques de traitement du signal numérique pour assourdir de manière plus sûre des segments non nécessaires d'un récepteur FM, réduisant ainsi le bruit et la consommation de courant. Des échantillons numériques d'un signal FM ayant des composants réels (en phase) (I) et imaginaires (en quadrature de phase) (Q) représentent les composants réels et imaginaires d'un vecteur tournant en rotation autour de l'origine d'un système de coordonnées cartésiennes à un taux indiquant qu'un signal est sur le canal, sont traités mathématiquement. Des échantillons numériques successifs sont multipliés (54) par le mélange complexe (55) d'échantillons temporairement voisins, produisant un nouveau courant de vecteurs tournants représentant le changement de phase entre les échantillons. Les changements de phase entre les échantillons sont traités (58, 59, 60, 62) pour donner un nombre qui indique la probabilité qu'il y ait du bruit dans le canal. Ce nombre indiquant la probabilité du contenu en bruit est comparé à une valeur de seuil et utilisé pour décider si les étapes de réception successives seront ou non assourdies.

Abstract: Procédé et appareil (1) servant à enlever de la graisse, des bactéries, des solides, et d'autres impuretés de l'eau utilisée lors du traitement des denrées alimentaires de sorte que sensiblement toute l'eau puisse être réutilisée. L'eau subit un filtrage grossier (4) puis est introduite dans la partie supérieure d'une tour (5) et se décharge de la tour (5) près du fond, où un mélange air/ozone est ajouté. Le flux à courant contraire du mélange air/ozone à travers l'eau porte des impuretés, notamment de la graisse, sous forme de mousse (80), qui débordent par-dessus le rebord de la tour (5). Ensuite, la mousse s'écoule vers un égout (12) à déchets. Un autre mode de réalisation prévoit une deuxième tour (55) en aval de la première tour (5), un filtre intermédiaire (54) étant situé entre les deux tours. Le filtre intermédiaire enlève les particules solides restantes et la deuxième tour (55) enlève des impuretés supplémentaires, telles que des protéines. Après la deuxième tour (55), l'eau passe à travers un filtre de polissage (60), une brosse à récupération d'ozone (61), et un appareil de chloration (62).

Abstract: The present invention provides a highly efficient method for the expression of heterologous genes, using as the host an auxotrophic his3 mutant of strain BKM-90 of  Pichia pastoris  and as recombinant DNA for the transformation thereof an integrative vector which contains a functional selection marker of  Saccharomyces cerevisiae , the promotor of the alcohol oxidase gene (AOX₁) of the yeast itself, as the transcription terminator that of glyceraldehyde 3-phosphate dehydrogenase (GAP) of  S .  cerevisiae , or that which is carried by the heterologous gene to be expressed, and another sequence homologous to the genome of  Pichia pastoris  which serves for the integration thereof. The expression vectors used further contain a heterologous gene bound to the signal peptide of the sucrose invertase gene (SUC2) of  S .  cerevisiae . This method guarantees that the polypeptide products are recoverable under controllable conditions and with high yields. The strains according to the present invention can be used for the large-scale production of pharmaceutical products or of enzymes of industrial interest.

Abstract: Frequency domain ECG signal processing systems and methods plot spectral maps and compute statistical parameters from surface electrocardiographic signals, which plots and parameters reveal abnormalities of electrical conduction within the hearts of patients at risk of ventricular tachycardia. Fourier analysis of short overlapping time segments of QRS ECG signal are used to create three dimensional spectral maps disclosing changes in the frequency spectral content of the ECG signal over the whole QRS region. Correlations and statistical evaluations of the spectral content between QRS time segment pairs quantify the spectral turbulence of the ECG and distinguish those at a risk from ventricular tachyarrhythmias.
