Abstract: In a process for reducing dyes in aqueous solution, a pair of electrodes is immersed in the solution. The cathode potential is maintained below the value at which hydrogen is evolved. A reducing agent is then used, the redox potential of which, increased by the charge transfer overvoltage required for the reduction of the oxidized form of the reducing agent to the reduced form at the cathode, is less than the cathode potential.

Abstract: Caméra à mise au point automatique effectuant cette opération de manière que les niveaux des composants haute fréquence des signaux d'image produits par un élément de formation d'image soient détectés sous forme de valeurs d'évaluation de la mise au point à des intervalles déterminés. L'une des spécifications techniques comprend la possibilité d'effectuer une mise au point très rapide. A cet effet, la lentille de mise au point est déplacée par pas approximatifs sur une plage allant de l'infini jusqu'à un point proche, afin d'obtenir des valeurs d'évaluation de la mise au point pour chacun des pas. Selon une première méthode, la lentille de focalisation est déplacée à une distance correspondant à une valeur maximale d'évaluation de la mise au point par l'organe de recherche, et cette lentille de mise au point est ensuite déplacée par petits pas afin d'obtenir une valeur réelle maximale d'évaluation de la mise au point. Selon une deuxième méthode, on obtient une valeur réelle maximale d'évaluation de la mise au point à partir d'une valeur interpolée d'évaluation de la mise au point obtenue par l'interpolation de valeurs d'évaluation de la mise au point qui sont avoisinantes entre elles et proches de la valeur maximale d'évaluation de la mise au point obtenue par ledit organe de recherche.

Abstract: A pellet press (1) is equipped with a control device by means of which it is possible to maintain a desired degree of pressing roller slip, for example none, or a presettable maximum value. 
<??>For this purpose, the pellet press (1) has a first measuring device (27, 28) for measuring the circumferential speed of the perforated die (8) and a second measuring device (23, 24) for measuring the circumferential speed of the pressing rollers (11, 12). The two circumferential speeds are compared in a comparison device (30, 31) and when a preselectable maximum value for the difference of the two measured values is exceeded, a slip signal is generated by means of which the press drive and/or the feeding of starting material to be pressed is influenced in such a way that the slip is suppressed.

Abstract: A technique is described for the production of manufactured articles of composite material of large thickness, the matrix of which is composed of polymerizable resins, using electron beams. To achieve the polymerization of the matrix, it is proposed to induce the adhesion of the resin of a layer (1) of already polymerized material with the resin of a second layer (3) to be polymerized by irradiating the second layer and the zone of adhesion between the first and the second layer with electron beams (F) of appropriate energy. The method can also be used for the welding of a plurality of layers or portions of already polymerized material. This permits the polymerization of matrices of such a thickness as not to be penetrated in a single phase by electron beams of limited energy. The treatment by successive phases performs the polymerization of the resin matrix in a manner equivalent to a simultaneous treatment over the entire thickness. <IMAGE>

Abstract: A combination electric motor and transmission unit device has two inputs and a rotational mechanical output, at least one of the inputs being of electrical power, to a corresponding integral combination of an electric motor means with a transmission means. The directions of rotation and the rotational speeds of the two inputs can be controlled to provide the mechanical output at any desired rotational speed with peak power output, depending on the controls, thus providing an ideal infinite speed device. The device employs a novel arrangement of a differential unit or a planetary gear unit. The combined motor and transmission device is lightweight, requires a small number of moving parts, and is useful in vehicles powered by electricity, including for regenerative braking. Another embodiment of the drive device is useful for a flywheel for peak power supplementation and also regeneration.

Abstract: L'invention se rapporte à un procédé, à un dispositif d'identification et à un dispositif de vérification servant à identifier et/ou à réaliser une signature numérique permettant un contrôle d'accès à la connaissance zéro. Dans de nombreuses applications, par exemple des cartes de crédit, des passeports, des clés éléctroniques ou systèmes analogues, il est nécessaire d'utiliser des systèmes de contrôle d'accès ou de signature numérique infalsifiables. Ces systèmes de contrôle d'accès et de signature peuvent comprendre des codes publics. Mais, dans la plupart des systèmes de codes publics, la gestion du code devient très compliquée au fur et à mesure que le nombre des usagers augmente. L'invention utilise le fait qu'il est difficile de calculer un modulo n de racines quand la factorisation de n est inconnue. L'invention est basée sur l'identité suivante: xd(x-1)d = 1 modulo n qui est calculé et vérifié entre un dispositif d'identification et un dispositif de vérification. Un organisme autorisé enregistre les données de départ, le modulo n, une fonction pseudo-aléatoire et un ensemble de nombres calculés à partir du modulo n des racines dans un dispositif d'identification. Le répertoire de codes publics est remplacé par une transmission unique de données de départ depuis l'identificateur vers un vérificateur qui donnera, après un traitement approprié, à la fois l'information sur l'identité destinée à l'identificateur et le code public.

Abstract: Described are preferred processes for recovering citric acid from a medium in which it is contained. The citric acid is recovered both effectively and in a form which is readily purifiable. In one preferred process, the citric acid-containing medium is contacted with a solid-phase free base resin having tertiary amine groups to adsorb the citric acid. The citric acid is then desorbed by displacement with a stronger acid, and a citric acid-containing fraction is collected substantially free from contamination by the stronger acid. In another preferred process, a citric acid-containing medium is contacted with a solid-phase polymer having pyridine functions to adsorb citric acid, the contacting being at a temperature below about 40  DEG C. Adsorbed citric acid is then desorbed with hot H2O at a temperature of at least about 75  DEG C. Unnecessary impurities such as those arising from the use of organic solvent or throughput inorganic acid desorbents are thereby avoided while at the same time achieving a commercially attractive recovery of the citric acid. Additional preferred modes and process features are also described.

Abstract: A turbo engine is provided with several sequentially configured chambers (18a,b, 19, 29, 30a,b, 27) in which intake, precompression, final compression, ignition, combustion, expansion and gas discharge take place in parallel during one revolution. The gas flow through the individual chambers is controlled symmetrically in rotation in the logic of this engine via a central gear shaft (52) by gear wheel transmissions (53a,b,c, 15, 17, 39, 40, 41) and by cylinders (3, 22) and pistons (1, 2, 11, 23, 24, 25) which rotate in/about the chamber(s). It is expected that the configuration and mode of operation described will significantly improve efficiency by comparison with conventional engines and thereby considerably reduce fuel consumption and environmental damage. The design of the engine offers many possibilities for further development and optimization of all the operating parts.
