  • Publication number: 20040194540
    Abstract: The invention relates to a device and a method for monitoring the dispersibility of solid formulations. The single-measurement method involves measuring the course of the dispersibility of a sample in a fluid over time. The build-up measurement method involves detecting hard particles in a dispersion. The device according to the invention is equipped with a pump, a flow meter, a charging receptacle for the sample, and a filter element, all of which are connected to each other via a fluid circuit, wherein the filter element is arranged downstream behind the charging receptacle with respect to the direction of flow as predetermined by the pump.

  • Patent number: 6079911
    Abstract: A device for the contamination-free conveying of powders which has a movable cone arranged within a discharge hopper, which, when in an open position, forms an annular gap between itself and the wall of the hopper. The amount of powder which is discharged through the annular gap is controlled by the amount of time the cone remains in the open position. The powder which is discharged from the hopper is supplied to a liquid jet pump, and is conveyed by the liquid jet formed by the liquid jet pump to a dispersing or dissolving tank.

  • Patent number: 5476845
    Abstract: A new process for preventing the crystallization of certain azole derivatives in the spray equipment upon spraying mixtures containingA) certain azole derivatives which have a tendency to crystallize andB) if appropriate one or more other active compounds and additives,which process comprises adding at least one phosphoric ester of the formula ##STR1## in which R.sup.1 represents alkyl having 2 to 18 carbon atoms andR.sup.2 and R.sup.3 independently of one another represent alkyl having 2 to 12 carbon atoms,to the spray mixture before spraying.
