Ce dispositif (10) comporte un carrousel à axe horizontal (D) avec une pluralité de conteneurs (16) aptes à recevoir chacun l'un des produits respectifs. Les conteneurs sont disposés suivant une configuration circonférentielle et sont assemblés en succession les uns aux autres de manière à former une couronne monobloc autoporteuse (12, 14). Chaque conteneur comprend des moyens pour le solidariser de part et d'autre aux conteneurs attenants situés le long de la circonférence de la couronne. Pour supporter la couronne, le dispositif comprend un monorail semi-circulaire (22) s'étendant le long de la circonférence de la couronne, les conteneurs comprenant un organe de guidage et un organe de support (26) apte à reposer sur ce monorail.

White-pigmented and unpigmented base paints and stains are custom-tinted using an automated colorant dispenser having a minimum fluid dispensing quantity less than 0.01 fluid ounce ( 3 ) and an array of colorants including a green-hued colorant having a color strength greater than that of a comparison colorant containing 12 wt. % PG7 pigment, a blue-hued colorant having a color strength greater than that of a comparison colorant containing 7 wt. % PB 15:2 pigment, and a red-hued colorant having a color strength greater than that of a comparison colorant containing 17 wt. % PR209 pigment. The green-hued or blue-hued colorants are dispensed into the base paint or stain whenever a green-hued or blue-hued tint is required. Light pastel tints in small containers and strong colors in large containers may be prepared without requiring the use of additional colorants having the same general hue and lower color strength.

Ce dispositif (10) comprend une pluralité de conteneurs stockant différentes teintes respectives, un carrousel à axe horizontal portant les conteneurs disposés selon une configuration circonférentielle, et un support (18) pour un récipient collecteur (16). Le carrousel est indexé jusqu'à une position de prélèvement où l'orifice d'expulsion d'un conteneur sélectionné est disposé en vis-à-vis du récipient collecteur, des moyens de dosage commandant alors l'expulsion d'une dose prédéterminée de teinte dans le récipient collecteur. Le carrousel est par ailleurs entraîné en rotation permanente pour produire par rapport au contenu des conteneurs un champ de gravité tournant propre à éviter la sédimentation des particules présentes en suspension dans les teintes. Le carrousel comporte une pluralité d'alvéoles (14) définissant chacun un volume intérieur clos apte à loger de manière étanche une poche déformable souple contenant l'une des teintes de base. Le dispositif comprend en outre une source de pression et des moyens de mise sous pression du volume intérieur de l'alvéole préalablement à l'expulsion de la teinte de base.
摘要:
A System and method for measuring the viscosity of printing ink during the printing and ink correction process is presented. A Printing press comprises at least one ink supply system, with which ink can be transferred from an inlet point to the printing substrate, at least one optical measuring device for measuring actual optical values of light, in which the actual optical values are from light of selected wavelength ranges and in which the light has interacted with at least parts of the printing picture, whereby the printing press further comprises an ink mass determination device for determining the weight of at least parts of the ink which is located within an ink supply system a control and evaluation device which can be provided with measured values from the optical measuring device and with measured values from the ink mass determination device and which can be used to determine the optical deviation, that is the deviation of the actual optical values from the optical reference values, which are available as light intensity values of selected wavelength ranges, and which control and evaluation device can be used to determine on the basis of the optical deviation and the values from the weighing devices, how much corrective ink having a determined composition is fed to the printing press in order to approximate the actual optical values to the optical reference values.
摘要:
This invention relates to compositions and methods for treating subterranean formations, in particular, oilfield stimulation compositions and methods using water-in-water polymer emulsions to uniformly dissolve a Theologically active polymer, such as a thickener or friction reducer, in the treatment fluid. The emulsions have a low viscosity and are easily pumped for mixing into a treatment fluid, where upon dilution with an aqueous medium, the polymer is easily hydrated without forming fish-eyes. The partitioning agent in the water-in- water emulsion does not generally affect the rheology of the treatment fluid. The invention also relates to further processing of the emulsion by wet grinding, high shear mixing and/or heating to enhance the hydration rate in the preparation of the well treatment fluid.

Methods and fluid delivery systems mix fluids together. A blender of the system receives and blends at least two chemical compounds together for delivery to one or more vessels, tanks or process tools, such as chemical baths that facilitate processing (e.g., cleaning) of semiconductor wafers or other components. A first fluid enters into a bore of a mixing chamber of the blender through an aperture in a wall of the chamber to enable blending of the first fluid with a second fluid injected into a central region of the bore.
