Abstract: A system for optimizing the multi-extruder deposition process in a 3D printer including multiple extruders requires each extruder to have a body including an outer thermal insulation shell; the shell allowing the inlet/outlet of a fluid for the active and controlled refrigeration of the extruder. A method for optimizing the multi-extruder deposition process in a 3D printer with multiple extruders involves managing the temperature of each extruder using active refrigeration sized so as to have a sudden control of the cooling ramp and to manage the viscosity of the material in the event of extruder change. For the entire duration of the printing with another extruder, the unused extruder nozzle remains in a limited range around the extrusion temperature, thus eliminating downtime, while the solidified filament from the sudden forced cooling is pulled back into a low temperature nozzle area where it does not degrade during non-use.

Abstract: Synergistic mixtures of fungicidal N-(2,6-dimethyl-phenyl)-N-(1-methoxycarbonyl-ethyl)-phenylacetamide with other selected fungicides which are ethylene-bis-dithiocarbamates, N-trichloromethylthio-imides or copper oxychloride are disclosed as are compositions comprising the synergistic mixtures.Said mixtures and compositions are effective in controlling fungi infections of useful plants.

Abstract: There are disclosed arylhydrazo-aldoximes which, as such, as tautomers, and in the form of organic or inorganic salts thereof, are active in preventing and treating infections of useful plants by fungi, and in immunizing plants against such infections.

Abstract: There are disclosed new fungicidally active N-substituted ethylendiamino-dithiocarbamates, in particular such dithiocarbamates which are active against Plasmopara viticola infections (B. et C.) Berl. et de Toni (Peronoapora of the vine) and against infections by other fungi that are noxious to useful agricultural cultivations. An important characteristic of the new fungicidally active dithiocarbamates of the invention is that use thereof does not result in the formation of ethylenthiourea.

Abstract: Plastic films containing pesticides and useful as coverings for agricultural cultivations which also effectively protect the cultivations from both vegetable and animal pests (parasites) are disclosed, as are methods for obtaining and using the coverings.

Abstract: There are disclosed N-aryl-1,3-oxazolidine-2,4-diones of the formula: ##STR1## wherein: R=C.sub.1 -C.sub.5 alkyl; C.sub.1 -C.sub.5 haloalkylY=H; hydrogen, 3,4-dichloro; 3,5-dichloro; 3,5-difluoro; 3,5-dimethyl; 3,5-dimethoxy; 3,5-bis-trifluoromethyl; andA= ##STR2## wherein R is as previously defined. The N-aryl-1,3-oxazolidine-2,4-diones are useful fungicides, possess systemic action, and are particularly active in the field.

Abstract: A series of condensed heterocycles, more particularly condensates of triazolones with pyrazolones, which exhibit antibotrytical activity, are disclosed. A process for producing the new heterocycles, which are pyrozolo-triazol-triones, by reacting carbethoxy pyrazolones with isocyanates, in the presence of tertiary amines, is also disclosed.

Abstract: New, highly active fungicides which are N-acyl-S-haloalkyl, or S-halovinyl-thiolcarbamates are prepared by reacting a carboxylic acid, e.g., benzoic acid, with an imidoyl chloride, such as trichloromethylthiomidoyl chloride. These new fungicide thiolcarbamates are effective in fighting a wide range of fungi which attack useful plants, being particularly active against fungi belonging to the different orders Ficomicoeti, Ascomicoeti and Basidiomicoeti.
