摘要:
An apparatus for dosed dispensing of a plurality of different liquid or pasty masses to a receiving container. The apparatus includes: a first supporting device for supporting containers for the masses in fixed positions; a fixedly disposed annular frame bearing a plurality of dispensing nozzles controllable by a control device and each individually connectable to the containers via respective conduits; a second supporting device controllable by the control device for supporting the receiving container such that the receiving container is displaceable in an annular path corresponding with the annular form of the annular frame and placeable temporarily beneath a chosen dispensing nozzle for receiving mass dispensed by the chosen dispensing nozzle; a weighing device supported by the second supporting device and configured to support the receiving container, with the weighing device further configured to supply weight signals to the control device; wherein the weighing device is connected via the second supporting device to the control device by cables such that when the second supporting device progresses through a path extending through 360° net torsion of the respective cables is substantially zero.

An ink dispensing apparatus is comprised of a support frame capable of supporting a plurality of ink containers. The apparatus is provided with an agitating mechanism to agitate the containers from time-to-time to maintain the ink and coloring agent therein in admixture and substantially homogeneous, particularly before dispensing ink. Pressure is applied to the ink container to assist in the discharge of ink from a flexible dispensing spout which is connected to the mouth opening of each container. A scale is displaceable under each container and on which a vessel is supported for receiving a desired weight quantity of ink from selected ones of the containers which contain inks of different colors. The ink is dispensed by operating a hand-operable dispensing valve mechanism which closes and opens the flexible tube in a regulated manner.

An automatic fluid mixing device wherein a cylindrical supporting structure supports a first number of valves angularly spaced along a first circumference, and a second number of valves angularly spaced along a second circumference concentric with and inside the first; the valves are three-way types, and present a control rod extending axially from one end; and the mixing device presents a blade type selecting device movable angularly about an axis through the center of the circumferences, and which singly engages an end portion of the control rod to move the rod axially and so open the valve.
摘要:
A process for preparing aqueous pigmented ink jet inks with improved properties, comprising the steps of (a) charging a rubber two-roll milling apparatus with a pigment and a polymeric dispersant; (b) milling to obtain a dispersion of pigment with polymeric dispersant; and (c) dispersing the dispersion in an aqueous carrier medium.
摘要:
In accordance with this invention there is provided a process for the preparation of pigmented ink jet inks comprising:(a) mixing at least one pigment and at least one pigment dispersant in a dispersant medium to form a pigmented ink mixture wherein pigment is present in an amount up to 60% by weight based on the total weight of the mixture;(b) deflocculating the pigmented ink mixture by passing the pigmented ink mixture through at least a plurality of nozzles within a liquid jet interaction chamber at a liquid pressure of at least 1,000 psi to produce a substantially uniform dispersion of pigment particles in the dispersant medium.
摘要:
A marking apparatus comprises a plurality of containers of colored inks and a solvent connected to a mixing chamber and a rotating applicator. Insulated wire is marked by passing it through the applicator housing which collects the excess colored ink. The excess ink may be returned selectively to either the mixing chamber or a disposal container. Solvent purging of the system permits rapid changeover of colors.
