Inventor: TAYLOR JAMES MARTIN
IPC: C08B9/00
Filed: 1992-02-13
Abstract: On obtient un élément oblong de matériau cellulosique, tel que de la fibre, présentant une tendance réduite à la fibrillation grâce à un procédé de filage de solvant qui comprend les étapes suivantes: (i) dissolution de la cellulose dans un solvant miscible à l'eau de façon à obtenir un dope, (ii) passage forcé à travers au moins un orifice de façon à obtenir une forme oblongue, (iii) passage de la forme oblongue à travers au moins un bain contenant de l'eau afin de retirer le solvant et produire l'élément oblong, et (iv) séchage de l'élément oblong de manière à obtenir un élément allongé sec. Le procédé est caractérisé par le fait que le pH du bain ou de chacun des bains à travers lesquels la forme oblongue et l'élément oblong passent lors du traitement entre la production de la forme oblongue et le séchage de l'élément oblong est maintenu à une valeur inférieure ou égale à 8,5.

Title: Systeme de nettoyage d'eau contaminee
Inventor: GILLHAM ROBERT WINSTON
IPC: C02F1/70
Filed: 1992-04-24
Abstract: Le traitement d'eau contaminée par des hydrocarbones organiques comprenant le chloroforme, le trichloroéthane, les solvants, les pesticides, etc. consiste à faire passer l'eau à travers un mélange de charbon actif perméable et des limailles de fer. Lorsqu'on applique une tension négative Eh, le métal provoque la décomposition chimique des contaminants. Le charbon actif agit de façon à retarder le contaminant, lui conférant un temps de séjour avec le fer important. Les conditions de tension Eh négative imposant l'exclusion de l'oxygène, une application préférée consiste à placer le mélange dans une tranchée au-dessous de la surface de la nappe souterraine dans une zone aquifère, dans la trajectoire d'une colonne de contaminant. Le mélange peut également être contenu dans un réservoir situé au-dessus du sol ou dans ce dernier. Une charge inerte, telle que du sable, peut être additionnée au mélange.

Abstract: L'invention se rapporte à un procédé pour la production de composés chiraux de grande pureté optique, dans lequel on utilise des enzymes pour catalyser une réaction entre un matériau de départ chiral et un matériau de départ non chiral dans du dioxyde de carbone surcritique, pour qu'essentiellement un seul des isomères optiquement actifs du matériau de départ chiral réagisse et produise un nouveau composé chiral ayant une pureté optique plus grande que le matériau de départ. En utilisant du dioxyde de carbone surcritique comme milieu de réaction, les problèmes et les risques liés à la manipulation de grandes quantités de solvants organiques sont évités.

Abstract: L'invention concerne un système d'évent (11) conçu pour être installé sur un récipient standard à l'emplacement d'un bouchon pour le transport et le stockage. Ledit système permet d'éventer le récipient sans qu'il soit nécessaire de le modifier. Ce système d'évent est constitué d'un bouton (21) que l'on tourne dans un sens pour mettre ledit système d'évent en position de fermeture, pour transporter, par exemple le récipient, et que l'on tourne dans le sens inverse pour mettre le système d'évent en position de fonctionnement, c'est-à-dire pour laisser entrer de l'air dans le récipient lors du soutirage du fluide. Un boîtier d'évent (13) conçu pour être vissé dans une ouverture filetée du récipient (23) est prévu. Le bouton est constitué d'un chapeau (15) et d'un anneau (19) qui sont maintenus ensemble par un sceau révélant une tentative d'ouverture (17). Ledit bouton est bloqué par le carter de l'évent afin d'empêcher qu'il ne soit enlevé et d'empêcher l'accès au récipient. Le sceau révélant une tentative d'ouverture doit être enlevé pour accéder au carter de l'évent et pour enlever le système d'évent du récipient. Dans un autre mode de réalisation, il est prévu d'empêcher toute fuite de fluide du récipient par le système d'évent au cas où ledit récipient serait renversé.

Abstract: Un dispositif permet de mesurer la pression régnant dans une section de puits sous-marin. Il comporte une partie fixe montée à l'extérieur de la section de puits et une partie mobile que l'on descend en position, au-dessus de la partie fixe, chaque fois que l'on souhaite contrôler la pression. La partie fixe comprend une jauge de contrainte qui permet ce contrôle en mesurant les contraintes qui s'exercent dans la section de puits. La partie fixe est munie d'un émetteur qui émet des impulsions lumineuses correspondant à la pression mesurée. La partie fixe est aussi dotée d'une cellule photo-électrique qui reçoit le faisceau lumineux provenant de la partie mobile. Ce faisceau lumineux et la cellule photoélectrique fournissent l'énergie nécessaire à la partie fixe. La partie mobile comporte un récepteur qui reçoit les impulsions lumineuses de l'émetteur et les corrèle avec une mesure de pression.

Patent EP-0554808-A1 (EP)
Inventor: WAN GANG DR-ING
IPC: C22C1/00
Filed: 1993-01-29
Abstract: The invention relates to a process for producing shaped parts made of metal alloys, in which the metal alloys are brought into the molten state and according to conventional casting methods are cast to produce geometrically simple shapes, which is followed by heating to a temperature between the solidus and the liquidus line to form a thixotropic slip, which consists of a solid-liquid mixture of rounded primary particles homogeneously distributed in a melt matrix and which after a holding time is passed to a shaping system. The object of the invention is to simplify and make more economical the preparation of rheo-alloy blanks having a close-grained and homogeneous microstructure. To this end it is provided that the metal alloys are admixed in the molten state with an amount of grain refiner which is increased compared to conventional grain refining, said increased amount being determined from a curve of a diagram in which the particle size in  mu m is plotted against the addition of grain refiner in per cent by weight, said curve being known for the individual alloys and grain refiners and having a steeply descending first branch and a second branch proceeding asymptotically towards a final value of the particle size, the determination being carried out in such a way that the addition of grain refiner is selected as a value on the second branch of the curve; that the metal alloys are then cooled down to any desired temperature below the solidus line and are then heated to a holding temperature between the solidus and the liquidus line and in the process are held for a holding time of less than 15 minutes. <IMAGE>

Abstract: An air-conditioning installation with, at the inlet, a mixing chamber for mixing outside air with circulating air, a preheater, a cooler, a humidifier, for example an air washer, and a reheater, is to be controlled in such a way that an amount of outlay reflecting the operating outlay, for example the sum of the absolute values of the enthalpy changes caused by the activated units, is minimal. For the purpose of selecting the units to be activated, first state trajectories proceeding from an initial state (full circle) and second state trajectories leading to the desired state (x) are determined in the hx diagram, possible transitions are determined by calculating the sectional state (S; S'; S''), and the corresponding amounts of outlay are calculated. The possible transition with the lowest amount of outlay is selected, that is to say the corresponding units are activated and are controlled with the effect of bringing about the transition, for example by regulating the mixing chamber in terms of temperature and the humidifier in terms of moisture. <IMAGE>

Abstract: In an X-ray tube for an X-ray analysis apparatus an optimized minimum working distance is achieved, together with an adequately high radiation yield, by integrated optimization of the radiation end of the tube, the position and the mounting of the exit window (6), and the electron-optical configuration (8,10) in the tube. This results in an X-ray tube having a conical end (16), an angle of cone of approximately 45° and the use of the cone as such in the electron-optical system of the tube. Exact determination of the anode (14) position relative to a reference face outside the tube enables exact positioning of each individual tube in an analysis apparatus.

Abstract: The frequency of a timing signal generated by a timing source apparatus (102) for battery-operated, clock-driven electronic devices (105) is reduced in a predetermined manner as the battery (101) voltage decreases. The timing source is electrically connected to the internal clock of the device to dictate the speed of that clock. As the frequency of the timing source (102) is decreased in response to lower battery voltage, the internal clock speed of the device is proportionately reduced, causing reduced power consumption and prolongation of the life or charge cycle of the battery (101).
