Abstract: L'ensemble à ébavurer décrit (10), qui sert à enlever les bavures, les barbes et autres protubérances de la surface de pièces coulées, se compose d'un corps de rouleau cylindrique (12), adapté dans des montures d'extrémités (11), constituées par exemple par des paliers de grande résistance, et pourvus de multitudes de marteaux (14) disposés en groupe (15) s'étendant radialement depuis le corps de rouleau (12) et protégés par des barres de retenue (16) contre les effets de chocs et de la rotation. Les barres de retenue (16) s'étendent de part et d'autre de chaque paire de marteaux (14) et sont elles-mêmes fixées dans des fentes (32) de plateaux de support annulaires (18), de façon à être maintenues au plus de niveau avec les bords du plateau (18) au moyen de soudures biseautées (22, 34). Chaque plateau de support annulaire (18) présente huit ouvertures à espacement équiangle entre elles (34), qui sont alignées pour recevoir et retenir huit tiges (26), lesquelles s'étendent parallèlement à l'axe du rouleau (12), à petites distances des cordons (20), et sont maintenues en place au niveau des plateaux d'extrémités (18, 18b) par des disques de retenue (28) assujettis aux plateaux d'extrémités. Les marteaux (14) comportent à une de leurs extrémités des ouvertures (13), grâce auxquelles ils sont soutenus en rotation sur les tiges (26), et sont montés de façon à tolérer un léger mouvement radial. Chaque paire successive de groupes de marteaux (15) est désaxée de 45° par rapport à la paire précédente. Ces mesures servent à compenser les variations de hauteur et de courbure, par exemple des plaques entrant dans l'ensemble. Ce dernier peut être utilisé de façon continue en ligne avec la table à rouleaux de sortie d'une installation de coulée en continu ou dans une variante, lors du traitement par lots de matériaux semi-finis.

Abstract: PCT No. PCT/GB89/01497 Sec. 371 Date Jul. 23, 1991 Sec. 102(e) Date Jul. 23, 1991 PCT Filed Dec. 14, 1989 PCT Pub. No. WO90/07020 PCT Pub. Date Jun. 28, 1990.A two-stage method of producing N2O5 in nitric acid from N2O4 in nitric acid consists of a first production stage in which the anodic oxidation of N2O4 in nitric acid and cathodic reduction of nitric acid are separated by a non-ionic or anionic ion exchange membrane, and a second production phase in which the product of the first stage anodic reaction is subjected to further anodic oxidation, the anodic and cathodic reactions being separated by a cationic ion exchange membrane. The use of a cationic membrane in the second stage promotes, through leakage of N2O4 to the catholyte, an increase in N2O5 concentration and decrease in N2O4 concentration within the anolyte acid while avoiding a significant loss of current efficiency. The two stages may be connected in series and operated continuously to produce a nitric acid solution containing typically 32 wt. % N2O5 and less than 2 wt. % N2O4.

Abstract: The method for producing of recombinant human cysteineless gamma-interferon free of methionine at N-terminal is used for preparing the precious therapeutical means gamma-interferon. It provides for a product yield exceeding 1.10 U/l culture thereby there is no need of applying monoclonal antobodies for purifying. The thus obtained gamma-interferon in which methionine at N-terminal has been discarded intracellularly has a purity of over 99.6%, it is maintaining its biological activity after lyophilizing and it is soluble in aqueous solutions. The method is accomplished in expressing the plasmid pIBM in strain Escherichia Coli LE 392 being recorded in the National Depositing Centre for industrial microorganisms and cellular cultures under Nr 845 and then cultivating it in a fermentator at temperatures from 36° to 38°C under conditions of aeration, thereafter the thus obtained product is purified, renaturated and eluted while the accompanying solvents and admixtures are removed.

Abstract: A fully automatic torque converter transmission is presented that uses a "V" belt (52) with inner teeth (53) that engage mating teeth on a variable pitch pulley (39) core in a low speed high torque state transformable into an infinitely variable higher speed shift mechanism. The bicycle pedal sprocket (17) drives a pivoted cluster of three small sprockets (26,27,28) with a drive chain loop interconnect driving a first sprocket as a driven member, and the other two serving as idlers in maintaining the chain at constant length. A speed ratio of approximately 1:6 from the pedal sprocket to the driven sprocket optimizes torque transmission capacity of the system with the driven sprocket attached to a self-centering, spring loaded, variable pitch pulley. This pulley has a core (37) shaped like a timing belt pulley with grooves (47) (or teeth) at its surface. The "V" belt driven by the variable pitch pulley drives a timing belt type pulley that rotates on a center fixed relative to the bicycle frame, and is a "V" belt with teeth on its inner surface enabling engagement with the variable pitch pulley core at the low speed high torque position. This converts the friction "V" belt drive to a positive drive in low gear. The driven pulley, finally, drives the rear wheel (13) through a conventional bicycle chain (21).

Abstract: The present invention is directed to a reagent for RNA detection comprising at least both reverse transcriptase and thermostable DNA polymerase, and a RNA detection method using the reagent. 
     The present invention makes it possible to perform the reverse transcription reaction in the same reaction solution as with the PCR reaction. This obviates the necessity of transfer of the reaction solution and replacement of the buffer system, thus making it possible to produce an amplified DNA fragment solely by controlling the reaction temperature, whereby the detecting operation is significantly simplified and the time required before detection is shortened.

Abstract: An anti-noise circuit dissipates parasitic tank circuit energy which causes ground undershoot and V cc  overshoot in the power rails (PG,PV) of an integrated circuit device. An anti-noise circuit transistor element, either an anti-undershoot circuit transistor element (AUCT) or an anti-overshoot circuit transistor element (AOCT) incorporates selected resistance in its primary current path for providing dissipating resistance. The anti-noise circuit couples a current source (PV), the anti-noise circuit transistor element (AUCT,AOCT) with dissipating resistance, and power rail parasitic lead inductance in series in a sacrificial current path. A control circuit coupled to the control node of the anti-noise circuit transistor element (AUCT,AOCT) causes sacrificial current flow following switching of potential levels at the output for dissipating parasitic tank circuit energy. The control circuit incorporates an active pullup and pulldown passgate (RST1,ICT1,OCT1) (RST2,ICT3,OCT2) between the data input (V IN ) and the control node of the anti-noise circuit transistor element. The passgate includes a pullup passgate transistor element (RST1,ICT3) and a pulldown passgate transistor element (ICT1,RST2) coupled for active turn off of the anti-noise circuit transistor element following a switching of potential levels at the data input (V IN ).
