| 20120003386 | METHOD FOR PRODUCING AMORPHOUS METAL ORGANIC MACROMOLECULES, MATERIAL OBTAINED BY SAID METHOD, AND USE THEREOF - The present invention relates to a method for producing a material suitable for producing ceramic oxide coatings, comprising the following steps: (a) preparing at least one first compound of a metal cation, selected from the cations of manganese, cerium, gadolinium, and/or yttrium, having at least one organic anion or an anion comprising an organic part, (b) dissolving or suspending the compound(s) prepared according to (a) in a protic, hydrolytically active solvent, such that the compound(s) is (are) present in a completely dissolved or colloidally dispersed form, (c) heating the suspension or solution thus formed in a closed vessel to at least 80° C., and (d) expanding and cooling the suspension or solution thus formed. Using said method, amorphous macromolecules are obtained, comprising molecular or polycyclic complexes having a primary particle size of <1 nm and an agglomerate size of 5 to 120 nm, preferably 10 to 80 nm. Applied to a substrate as a solution or suspension, said particles yield a coating material by means of which dense oxide coatings can be obtained even at relatively low temperatures. | 01-05-2012 |

| 20100302053 | SWITCH HAVING A FLAT DISPLAY - A switch, particularly a switching device or operating device, includes a flat display, wherein the flat display is provided for the visual display of at least one item of information related to a current or future condition of the switch or a system or machine associated with the switch. A more effective spatial arrangement of the switch components, and reduced energy consumption, is accomplished by a flat display of the switch of at least one embodiment, at least partially including an electrochromic material and electrodes. The electrodes are provided to supply particular regions of the electrochromic material with an electrical voltage, in order to thus activate a color change, and to provide one or more items of information to the use by means of an intelligent control | 12-02-2010 |
