Inventor: TANAKA MICHIO C O MITSUI PETRO
IPC: C07C37/84
Filed: 1989-11-20
Abstract: A process of producing isopropylnaphthols by oxidizing diisopropylnaphthalenes with molecular oxygen in a liquid phase to provide a reaction mixture which contains therein diisopropylnaphthalene monohydroperoxides and then acid decomposing the monohydroperoxides to isopropyl-­naphthols, is characterised by separating an organic layer from the reaction mixture, adding a aliphatic alcohol of 1-4 carbons to the organic layer, and crystallizing the diisopropylnaphthalenes while allowing the diisopropylnaphthalene monohydroperoxides to remain dissolved in the organic layer thereby to separate the monohydroperoxides from the diisopropylnaphthalenes. 
     In a further embodiment the isopropylnaphthols are crystallised from aromatic hydrocarbons of 6-12 carbon atoms.

Abstract: The present invention relates to a directly heated thermoelectron emission cathode. It consists of a hollow perforated cylindrical base structure made of pyrolytic graphite which is covered with a layer of the thermoemissive material. The loss of thermoemissive material by evaporation is limited by depositing a layer of a refractory material onto it. The refractory material is a compound of boron and a transition metal, or a compound of boron and a metal of the platinum type, or a compound of silicon and a metal, or a metal carbide. Application to cathodes for high power electron tubes or for electron microscope filaments.

Abstract: A process and apparatus for the ultrapurification of cryogenic low boiling liquified gases such as oxygen and nitrogen which contain trace impurities. The impure gas (20) is introduced into a first distillation column (32) and is substantially at its liquid-gas equilibrium temperature at the pressures within the first distillation column. Here the gas is separated by distillation into a first vapor fraction (100) containing low boiling point impurities and a first liquid fraction (38) containing high boiling point impurities. The first vapor fraction is withdrawn and introduced into a second distillation column (52).The first vapor fraction is substantially at the liquid-gas equilibrium temperature at the pressures within the second distillation column. Here the vapor fraction is separated by distillation into a second vapor fraction (94) containing high boiling point impurities and a second liquid fraction (60) free of trace impurities which is withdrawn as product. Cooling for the process is provided by indirect heat exchange with a cryogenic low boiling gas such as nitrogen, oxygen, or air. The gas to be purified as well as the heat exchange gas can be obtained from a standard air separation unit or the process can be conducted using gases obtained from storage.

Abstract: A suction device (1) is used by the mobile set to automatically hook to the putting-out mouth of the station on the ground, which device lets the containers flow together into a hopper (3) by means of a ventilator (2). The loaded material is broken by a turning breaker (8) and falls into a centrifuge (10) where the liquids are separated from the plastic materials. Subsequently a magnetic end instrument (12) keeps back the metal parts whereas the plastic one is at first grinded by a mill (13) and subsequently arrives in a tank (15) wherein washing and degreasant solutions are contained. At the end of the flotation, the product is then discharges, by means of a valve (17), into a lower tank (16) where, in presence of an agitator, a salt solution is used which lets the light materials float whereas the heavy ones sediment on the bottom. Through a valve (18) the product is at last discharg­ed into a centrifuge (19). The drainage product gets out from a higher outlet of this centrifuge and is sent by a fan (2) into a pipe (20) and by a deflector (21) to the stockage containers (22 and 23).

Abstract: When a blood is collected into a blood container, the present invention relates to a blood collection apparatus equipped with blood collection quantity measurement means having a measurement sensor for measuring the blood collection quantity and control means for calculating the blood collection quantity on the assumption that the output y of the measurement sensor constitutes a function y = f(w) with respect to an n-dimensional measured blood collection quantity w. The control means acquires the output yi of the measurement sensor for each of (n + 1) known blood collection quantities wi and calibrates constants constituting y = f(w) on the basis of this acquired data. The control means acquires automatically the output yO of the measurement sensor under a state where a measured blood collection quantity w is zero at a predetermined cycle, and corrects the offset value of y = (w) on the basis of this yO.

Abstract: The invention relates to a pushbutton arrangement for actuating a controllable element of a watch, having a button head 1 which projects radially from the watch case 16 and which is arranged so as to be axially displaceable. Located on the button head 1 is an actuating tappet 10 which can be displaced axially through a recess 15 in the watch case 16 axially into the case interior by means of the button head 1 and by which the controllable element can be actuated. At the same time, the button head 1 and actuating tappet 10 can be spring-loaded towards the housing interior. The button head 1 and actuating tappet 10 are displaceable axially relative to one another counter to a spring force. In the position of the button head further from the case, the actuating tappet 10 can be blocked in its position external to the case by a locking element fixed to the case. In the position of the button head 1 nearer to the case, the locking element can be moved by the button head 1 into a position cancelling the blocking of the actuating tappet 10. <IMAGE>

Abstract: L'invention concerne un récepteur adaptatif de signaux numérique s à division dans le temps, dans un système radio mobile numérique, comprenant deux branchements ou plus, recevant les signaux non mis en corrélation, provenant du même nombre d'antennes (A, B). On utilise les signaux de chaque branchement, codés sous forme numérique après démodulation et échantillonnage, afin d'estimer la réponse en impulsion des canaux (RIC), et afin de produire des paramètres (sA, qA, sB, qB), lesquels sont traités à l'aide de signaux (pA, pB) représentant la puissance reçue à chaque branchement. Ainsi l'on obtient deux signaux (Zcom, Sc), lesquels commandent un élément d'égalisation (EQZ) permettant la reconstruction du signal reçu. Le procédé de combinaison permet de procéder à l'estimation de la réponse en impulsion des canaux, sur chacun des canaux reçus, le filtrage appareillé ainsi que l'addition des signaux résultants, pondérés en fonction du niveau de puissance et selon un facteur de qualité à l'aide duquel chaque signal a été reçu.

Abstract: Un procédé et un appareil permettent de générer des images échographiques de basse puissance et de haute résolution d'objets cibles sélectionnés, tant stationnaires que mobiles. L'appareil comprend un dispositif (12) de transmission d'une pluralité de signaux ultrasoniques vers une région sélectionnée du tissu et un dispositif de réception des signaux d'écho ultrasoniques correspondants à chaque signal transmis. Un corrélateur (14, 16) met en fonction d'autocorrélation et de corrélation croisées les signaux ultrasoniques transmis et reçus. Les signaux mis en corrélation sont additionnés, combinés en fonction de leurs taux et groupés en données sur l'amplitude de la visibilité, sur les phases de visibilité, sur les phases différentielles, sur l'amplitude de fermeture et sur les phases de fermeture (26a-26c) à des fins de traçage (27). Dans l'appareil et selon le procédé préférentiels, le traitement de l'image est non-linéaire, par un procédé (34) de traitement des signaux par soustraction itérative des lobes latéraux, afin d'éliminer le bruit des signaux, et/ou par un procédé de traitement des signaux par traçage hybride itératif.

L'invention concerne également le traitement des signaux afin de montrer le déplacement ou des modifications de l'objet cible après la réduction du bruit. Dans un mode préférentiel de réalisation, l'appareil et le procédé sont employés comme outils de diagnostic clinique afin de générer de manière non-traumatisante des images de haute résolution des tissus du corps.
