Abstract:
A description is given of electrochromic thin-film systems and their components, especially an improved electrochromic thin-film based on tungsten oxide and/or molybdenum oxide into which alkali metal ions are incorporated, an electrolyte which is improved in particular with respect to its conductivity and is based on pre-hydrolysed, organically modified alkoxysilane and on organic diol (triol), and an improved process for producing a noncolouring ion insertion layer based on cerium oxides and titanium oxides.
Abstract:
Luster pigments obtainable by treating titania-coated silicate-based platelets at from 400.degree. to 900.degree. C. with a gas mixture comprising a vaporized organic compound and ammonia are useful for coloring paints, inks, including printing inks, plastics, glasses, ceramic products and decorative cosmetic preparations.
Abstract:
Preparation of bluish luster pigments by treating titania-coated silicatic platelets with a reducing gas mixture, which comprises treating titania-coated silicatic platelets whose titania coating has a geometric layer thickness of from 10 to 60 nm at from 800.degree. to 900.degree. C. with a gas mixture comprising a vaporized organic compound and ammonia, and also bluish luster pigments based on silicatic platelets comprising a reduced titania coating with a geometric layer thickness of from 10 to 60 nm and CIELAB color coordinates -2.ltoreq.a*.ltoreq.2 and b*.ltoreq.-20 (measuring angle 20.degree., standard illuminant D65).
Abstract:
Metal and ceramic sintered bodies and coatings are produced using a combination of:(a) nanocrystalline metal or ceramic powder wherein less than 1% of the individual particles have a deviation of more than 40%, and no individual particles have a deviation of more than 60%, from the average grain size, and(b) at least one low molecular-weight organic compound having at least one functional group that can react and/or interact with groups present on the surface of the powder particles, the materials (a) and (b) being dispersed in water and/or a polar organic solvent as dispersion medium.
Abstract:
Luster pigments comprising coated, plateletlike, silicatic substrates wherein the coating comprises a layer consisting essentially of carbon and aluminum oxide, chromium oxide, cerium oxide, zirconium oxide, antimony oxide or mixtures thereof, are obtainable by applying carbon-containing compounds of the metals aluminum, chromium, cerium, zirconium, antimony or mixtures thereof with or without further carbon-containing compounds of the molecular formula (CH.sub.2 O).sub.n, where n is from 1 to 6 for one monomeric unit, to the substrate particles and then thermally decomposing the carbon-containing compounds on the surface of the substrate particles under oxygen-excluding conditions.
Abstract:
Mixtures useful as luster pigments for coloring paints, printing inks, plastics, decorative cosmetic preparations and ceramic products and usable in dry form in printing and coating processes consist ofA) iron oxide-coated aluminum particles andB) iron oxide-coated mica particles with or without a prior coating of a colorless, highly refractive metal oxide as essential components.
Abstract:
An equipment stand, in particular for dental implements, which consists of a carrier possessing holders for the dental implements or instruments. A stand which extends in a vertical direction, concurrently forms the carrier possessing the implement holders, so as to thereby eliminate a separate component as a carrier in the form of a cross-bar, and consequently avoids a complex construction. Furthermore, through a superimposed arrangement of the implement holders there is afforded a good overview of the implements which are located in the holders.
Abstract:
An equipment stand for dental implements, consisting of a support column mounting holders for the implements, wherein the holders are horizontally reciprocable; in effect moveable to and fro. The horizontally reciprocable holders facilitate that the mostly different kinds of implements which are positioned in the holder can be brought into a suitable nearness for gripping at the working location of the dental technician, and pursuant to need; for instance, for the creation of the free space which is necessary for carrying out any such work which is to be done without the above-mentioned implements, can be again moved away from proximity to the gripping location.
Abstract:
The viscosity of aqueous printing inks for gravure printing is adjusted by means of partially organophilic gels which contain plastics mixtures of at least one polymer swelling in water and at least one polymer not swelling in water or to an insignificant extent only, in a solvent mixture of at least two hydrophilic organic hydroxy compounds and one hydrophobic organic hydroxy compound. The printing inks prepared with the aid of the thickener mixtures of the invention contain up to 90% of water, and can be handled as textile printing pastes.Gravure printing inks on the basis of such plastics gels containing disperse dyestuffs are suitable for the manufacture of transfer printing paper sheets. Since the thickening system adjusting the viscosity contains aqueous alcohols, if any, and no solvents as usual in transfer printing inks, no special measures have to be taken with respect to flammability and explosion risks.
Abstract:
The heat-transfer coloring process using sublimable disperse dyestuffs can be applied on cellulosic materials if these are treated with an aqueous preparation containing a thickening agent and an addition compound of a lower alkylene oxide onto a compound having active hydrogen atoms. If the thickener is a synthetic polymer containing carboxy group the alkylene oxide addition compound can be omitted.
