Abstract: The invention relates to a process for encapsulating biologically active compounds in the form of substantially spherical microparticles, comprising the steps ofa) preparing an aqueous solution of surfactants, catalysts and monomers or prepolymers which are suitable for forming a crosslinked polycondensate,b) forming an emulsion of the substantially water-insoluble biologically active compound or mixture thereof in the solution a) by adding said solution under high shear force, andc) forming a solid capsule wall around the biologically active compound or mixture thereof by heating the reaction mixture to a temperature at which the crosslinking reaction tales place,which process comprises fusing the biologically active compound or mixture thereof and adding the melt to the aqueous reaction mixture at a temperature which is higher than the temperature of the reaction mixture.

Abstract: One object of the invention, therefore, is to provide encapsulated biologically active solid microparticle agglomerates, each agglomerate comprising eitherIi) at least two closely associated microparticles, each microparticle being coated partially or completely by at least one discrete layer of a polymer, andii) at least one outer discrete coating layer of the same polymer which envelops the coated microparticles to form an agglomerate of closely associated microparticles, orIIi) a cluster of at least two closely associated microparticles, each microparticle being coated partially or completely by at least one layer of a polymer, the microparticles adhering together through the polymer to form said cluster, andii) at least one outer discrete coating layer of the same polymer which envelops said cluster to form a discrete agglomerate, wherein in types I and II an inter-phase boundary is formed between each particle and the first coating layer, between individual coating layers and between the outer agglomerat

Abstract: Internally cross-linked albumin microspheres their surface being modified by attachment of polyoxy(C.sub.-)alkylene chains having a terminal ether group, especially such containing pharmacologically active agents, usable for pharmaceutical compositions.

Abstract: The invention relates to a novel formulation of per se known pesticides in the form of microcapsules, to a process for the preparation of microcapsules and to the use of said microcapsules for controlling weeds, plant diseases, insects and representatives of the order Acarina.

Abstract: A process for the preparation of microcapsules, which comprises rapidly stirring an aqueous solution of a precondensate of urea and a dialdehyde in the molar ratio of urea to dialdehyde of 1:1 to 1:2.5, into an acidified aqueous dispersion of a water-immiscible pesticide or a readily volatile water-immiscible solvent.

Abstract: The invention relates to aqueous formulations containing 1 to 70% by weight of an agrochemical active substance which is sparingly soluble in water, besides an amount which inhibits crystallization of the active substance or breaking of the emulsion, of a compound of the formula IR--O--M (I),whereR is C.sub.12 -C.sub.20 alkyl; C.sub.12 -C.sub.20 alkenyl; phenyl; 4-biphenylyl; phenyl which is disubstituted to trisubstituted by .alpha.-methylbenzyl or .alpha.-methyl-4-methylbenzyl; or phenyl which is monosubstituted to trisubstituted by alkyl, the total of the carbon atoms in the alkyl groups being 1 to 18; andM is hydrogen; a cation equivalent of an alkai metal ion or alkaline earth metal ion; or, in the event that R is phenyl, 4-biphenylyl or phenyl which is substituted by .alpha.-methylbenzyl, .alpha.

Abstract: A safety receptacle or contact system for use at the outlet end of an electric supply line and for connection of at least one attachment plug that has at least two contact pins; the receptacle comprises a base plate; at least two connector ends supported by the base plate; a lid or cover housing including a front plate having at least two openings for receiving the plug pins and for guiding them into contact with the connector ends; an electrical circuit associated with the receptacle for controlled connection of the connector ends with the electric supply line and comprising a relay for breaking contact between the connector ends and the supply line when the two plug pins are withdrawn from the receptacle; and a light barrier connected with the relay for control thereof and arranged for operation in response to connection or non-connection of the plug with the receptacle.
