    摘要: Interference pigments based on multiply coated plateletlike silicatic substrates comprisingA) a first layer comprising a colorless or selectively absorbing metal oxide with a high refractive index,B) a second, non-selectively absorbing, semitransparent layer consisting essentially of carbon, a metal or a metal oxide, and optionallyC) a third layer comprising a colorless or selectively absorbing metal oxide in combination with scattering color pigments which are complementary in color to the reflection color of the interference pigments are useful for preparing valuable documents that are forgeryproof.

    摘要: A process is described for fixing an inorganic species in an organic matr which comprises bringing a compound of the formula MR.sub.n in which M is selected from sub-group metals, lanthanides, actinides, Al, Sn, B and Si, and the radicals R can be replaced by a complexing agent, into contact with a complexing agent, the complexing agent containing a functional group which is capable of participating in a polymerization or polycondensation reaction. After complexing, hydrolysis and condensation are preferably first carried out, followed by polymerization or polycondensation.

    摘要: A permanent magnet-excited rotor motor is disclosed wherein, a circuit board (6) mounted on a radial motor attachment flange (22) is arranged. The front and rear sides of the circuit board (6) are equipped with conductor strips. On the front side, Hall transducers (15) influenced by rotor magnets (81) in a speed dependent manner are mounted. A flat cable brought in from the outside is divided into a first cable portion (12), passed through from the front with supply and signal voltage lines for the Hall transducers (15), and into a second cable portion (13) passed through from the back to the front with winding feed lines for the stator coil winding ends (14), which are likewise passed through from the back to the front of the circuit board (6) and thus can be soldered to the freely accessible front side.

    摘要: Silicic acid heteropolycondensates made from hydrolyzable silicic acid derivatives and substituted silanes, optionally with either or both of one or more functional silanes and non-volatile metal oxides or their precursors are made by a known technique, in which the reaction mixture is hydrolyzed and condensed by the action of water and a condensation catalyst, the latter being employed in an amount up to 3% by weight, based upon the weight of the reaction mixture. Improved heteropolycondensates usable as adsorbents and porous membranes can be made by using greater amounts of catalyst, ranging up to 75% by weight, based upon the weight of the reaction mixture. These improved products are very stable in use and are characterized by a pore structure which includes fine pores and coarse pores, whereby products in the form of membranes can have an asymmetrical structure, if desired.
