摘要:
Plateletlike titanium dioxide reduction pigment consisting of titanium dioxide, titanium suboxides and, if desired, a further metal oxide or titanium oxynitride, obtainable by solidifying an aqueous solution of a thermally hydrolysable titanium compound on a continuous belt, detaching the resulting coat, coating the resulting titanium dioxide platelets, with or without drying in between, with further titanium dioxide by a wet method, drying and, if desired, calcining the material, and treating the material obtained with a reducing agent in a nonoxidizing gas atmosphere.
摘要:
Single-layer or multilayer titanate-containing pearlescent pigments comprising iron titanate and, if appropriate, titanium oxide and/or iron oxide, which is obtainable by solidification of an aqueous solution of a thermally hydrolysable titanium compound on a continuous belt, detachment of the layer formed, coating of the resulting titanium dioxide platelets, after or without intermediate drying, with iron oxide in a wet process, and drying and calcining of the resulting material in an oxidizing or reducing gas atmosphere at not less than 500.degree. C., the layer thicknesses of the titanium dioxide layer and iron dioxide layer being adjusted such that either the stoichiometric ratio between iron oxide and titanium dioxide necessary for the formation of pseudo-brookite or ilmenite is obtained or an excess of iron oxide or titanium dioxide is present.
摘要:
Plateletlike, substrate-free titanium dioxide pigment obtainable by solidifying an aqueous solution of a thermally hydrolyzable titanium compound on a continuous belt, detaching the resulting layer, coating the resulting titanium dioxide platelets, with or without drying in between, with further titanium dioxide by a wet method, and separating off, drying and calcining the material obtained.
摘要:
The invention relates to a sampling device (1) for a microreaction system (3), comprising an outlet (4) and a suction line opening (9) which is arranged next to the outlet (4). A depression can be produced in the suction line (9) for the suction of the substances (13) leaving the outlet (4). The outlet (4) is embodied as a capillary and can be positioned in relation to the opening of the suction line (9). The outlet (4) is surrounded by a housing (6) comprising a discharge outlet (14) for the substances (13) leaving the outlet (4), and a through-opening (8) for the suction line (9). Said suction line (9) opens up into a collecting tank (10) that is connected to a vacuum line (12) by means of an electrovalve (1).
摘要:
A microcomponent connection system (1) having an accomodation device for plate-shaped microcomponents (7) has a connection block (2) and a lifting device (6), by means of which the microcomponent (7) and the connection block (2) can be pressed against one another. The connection block (2) has electrical and fluid line connections (8, 9) and optical line connections (16), each of which projects in a sprung or spring-mounted manner on the underside of the connection block (2). In order to connect the microcomponent (7) to the associated line connections (8, 9, 16), the microcomponent (7) is pressed by the lifting device (6) in the direction of the connection block (2) against the electrical line connections (8) or fluid line connections (9) designed as electrically conducting spring tongues or as hollow rams (10), or optical line connections (16).

摘要:
The salts of N-unsubstituted, N-monosubstituted and N,N-disubstituted 7-(3-amino-2-hydroxypropyl)theophylline and 5-methylisoxazole-3-carboxylic acid are hypolipidaemic agents. The compounds, of which the 7-[3-(N-methyl-N-2-hydroxyethyl)amino-2-hydroxypropyl]-theophylline salt of 5-methylisoxazole-3-carboxylic acid is a representative embodiment, are prepared by allowing the isoxazole acid and the amine to react.
摘要:
A compound of the formula ##STR1## wherein R is hydrogen or methyl, n is a number from 1 to 4 and `Acyl` is nicotinoyl, 3-methylpyrazole-5-carboyl, 3-methyl-isoxazolyl-5-carboyl, 5-n-butylpyridin-2-carboyl, 2-(4-chlorophenoxy)-2-methyl-propionyl, 2-acetoxybenzoyl or theophyllinyl-7-acetyl, are useful for their effect on serum lipoids and, in particular, for treating adverse hyperlipidemic states in humans.
