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.

Method and device for the contamination-free metering and conveying of

A new process for preventing the crystallization of certain azole derivatives in the spray equipment upon spraying mixtures containing

Use of phosphoric esters as crystallization inhibitors

In the spraying of an aqueous liquor comprising at least one of 1-(4-chlorophenyl)-4,4-dimethyl-3-(1,2,4-triazol-1-yl-methyl)-pentan-3-ol and 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-ol, the improvement which comprises including in the liquor an N-alkyl-lactam of the formula ##STR1## in which R represents alkyl having 8 to 18 carbon atoms and

N-alkyl-lactams as crystallization inhibitors

Crystallization of active material in spraying of an aqueous solution of certain specified fungicides is retarded by incorporation therein of an N-alkyl-lactam of the formula ##STR1## in which R represents alkyl having 6 to 18 carbon atoms and

N-allyl-lactams as crystallization inhibitors

Crystallization of active material in spraying an aqueous solution of one of ##STR1## and is prevented by incorporation therein of an alkylcarboxylic acid dimethylamide of the formula ##STR2## in which R represents alkyl having 5 to 19 carbon atoms.

Alkylcarboxylic acid dimethylamides as crystallization inhibitors

In the spraying of an aqueous liquor comprising at least one of 1-(4-chlorophenyl)-4,4-dimethyl-3-(1,2,4-triazol-1-yl-methyl)-pentan-3-ol and 1-(4-chlorophenoxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-ol, the improvement which comprises including in the liquor di-styryl-phenyl-tri-glycol ether, whereby crystallization of II and III is reduced.

Di-styrl-phenyl-triglycol ether as crystallization inhibitor

The present invention relates to polycarbonate articles and films characterized by their antistatic properties comprising polycarbonate resin and alkali, or alkali earth, salts of specific aromatic sulfonic acids, specific aromatic phosphonic acids or aromatic partial phosphoric acid esters.
