    Abstract: PROBLEM TO BE SOLVED: To enable using of a coating suspension having a high solid substance content and make the position of a coated edge part inside a passage highly reproducible, sufficiently irrespectively of the cell density of a carrier. SOLUTION: The carrier is loaded starting with the lower end face by the filled volume of the coating suspension which is measured so that the carrier is loaded only upto the previously prescribed height of a part of the length L of the carrier. Thus the excess coating suspension is removed downward and a desired coating amount of the suspension is made to remain in the carrier.

    Abstract: PROBLEM TO BE SOLVED: To apply aspiration impact and quickly separate an excess coating dispersion from air current used for aspirating and releasing a catalyst support by vertically orienting a cylindrical axis, supplying a prescribed amount of a coating dispersion to the upper end face of the support from a storage container, passing the dispersion through flow routes by aspiration, removing the excess coating dispersion from the flow routes by opening the flow routes in aspirating condition, turning back the excess dispersion to the storage container, and firmly fixing the dispersion coating by firing. SOLUTION: Flow routes of a catalyst support are coated by passing a coating dispersion at 0.1-1 m/s flow rate by aspiration, removing the excess coating dispersion from the flow routes by applying aspiration impact from a lower side on completion of the passing of the dispersion by aspiration while controlling aspirating air flow rate at 40-1 m/s through the flow routes and removing the excess coating dispersion discharged together with the air flow from the air flow in less than 100 ms after discharge out of the catalyst support.

    Abstract: Delivery and dissemination of aqueous hydrophobic silicic acid dispersion includes passing the dispersion within a conduit and conveying the conduit onwards by squeezing motion. The squeezing motion is performed by hose pump, hose-type screw pump, peristaltic pump, or rotary positive-displacement pump. ACTIVITY : Acaricide; Insecticide. No biological data given. MECHANISM OF ACTION : None given.

    Abstract: The invention relates to a process for coating the flow channels in a monolithic, cylindrically shaped catalyst carrier with a coating dispersion, wherein the carrier has two end faces which are connected to each other by flow channels arranged parallel to the axis of the cylinder, by vertically aligning the axis of the cylindrical carrier, placing a predetermined amount of coating dispersion from a storage container on the upper end face of the carrier and drawing the dispersion through the flow channels under suction, removing excess coating dispersion from the flow channels by emptying the flow channels under suction, returning the excess dispersion to the storage container and fixing the dispersion coating by calcination. The process is characterised in that the coating dispersion is drawn through the flow channels under suction at a rate of flow of 0.1 to 1 m/s and that after completion of passage under suction the excess coating dispersion is removed from the flow channels by applying a suction impulse from below, wherein the suction air is drawn through the flow channels under suction at a rate of flow between 40 and 1 m/s and the excess coating dispersion discharged with the air stream is separated from the air stream within a time of less than 100 ms after discharge from the catalyst carrier.

    Abstract: The coating dispersion is sucked through the flow channels of a monolithic catalyst support at a rate of 0.1-1 m/s. Excess dispersion is removed from the channels by applying a suction impulse from below. Extraction air is sucked at a rate of 40-1 m/s through the channels and the excess coating dispersion removed from the air stream is removed from the air stream within a time from less than 100 ms after leaving the catalyst support. Process for coating the flow channels of a monolithic cylindrical catalyst support with a coating dispersion comprises vertically directing the cylindrical axis, charging a predetermined amount of dispersion from a storage vessel to the upper front surface of the support, sucking the dispersion through the flow channels, removing excess dispersion from the channels, returning the excess dispersion to the storage vessel and fixing the dispersion by calcining. The coating dispersion is sucked through the flow channels of a monolithic catalyst support at a rate of 0.1-1 m/s. Excess dispersion is removed from the channels by applying a suction impulse from below. Extraction air is sucked at a rate of 40-1 m/s through the channels and the excess coating dispersion removed from the air stream is removed from the air stream within a time from less than 100 ms after leaving the catalyst support.
