  • Patent number: 11826886
    Abstract: The proposed solution relates in particular to a method for assembling an engine assembly having a first engine component and a second engine component, wherein at least one fastening element is first of all arranged on an assembly aid, the at least one fastening element is arranged on the first engine component via the assembly aid and is held in an assembly position under the action of at least one magnetic element of the assembly aid, the at least one fastening element is fixed to the second engine component, and the assembly aid is removed again from the first engine component.

  • Publication number: 20230157284
    Abstract: The invention relates to an agrochemical composition comprising the potassium salt of dicamba and an adjuvant selected from a) a polyalkylene oxide block-copolymer, b) a hyperbranched polycarbonate, and c) a solvent selected from C1-C6-alkyl lactate, C3-C6-lactone and N—C1-C15-alkyl pyrrolidone. It also relates to a method of controlling undesired vegetation, and/or for regulating the growth of plants, wherein the agrochemical composition is allowed to act on the respective pests, their environment, or the crop plants to be protected from the respective pest, on the soil and/or on the crop plants and/or on their environment; to a method for producing the agrochemical composition; to an adjuvant composition for increasing the solubility of the potassium salt of dicamba in an aqueous composition comprising a mixture of additive a) or additive b) with additive c) fine droplet formation.

  • Patent number: 10703849
    Abstract: Carbon-linked 5-hydroxymethylfurfural (HMF) oligomers contain at least one first HMF unit and one second HMF unit. The first and second HMF units are linked by a carbon-carbon bond with involvement of an aromatically bound carbon atom at position 3 or 4 of the furan ring of the first HMF unit. The HMF oligomers may be used as reactive carbonyl compounds in the manufacture of thermally curable resins on the basis of phenolic compounds and/or aminoplastic forming agents as well as in the manufacture of wood composite products.

  • Patent number: 9416030
    Abstract: Within the scope of hydrothermal carbonization of biomass, not only the main product, coal, but also the platform chemical 5-hydroxymethyl furfural, as well as furfural and levulinic acid, are formed. These are extracted from the process water of the carbonization reaction. However, in this connection, the problem exists that humic substances deposit on the container walls of the extraction column and can only be removed again by means of great cleaning effort. Furthermore, oligomers clearly worsen the purity of the product. This problem is solved by a filtration cascade through which the process water passes before extraction. In this connection, first the impurities mentioned are removed in a first filtration stage, and the remaining products and educts are separated from one another in a second filtration stage. Only the products are passed to extraction.
