Abstract: A method for marking multiple components, each of which has at least one transponder and a storage device. A first marked component comes in contact with second components disposed in the range thereof and transmits information to them. The components mark themselves while taking the information transmitted by the first component into consideration. At least one second component after the marking thereof comes in contact with further components in the range thereof that are not marked yet in order to bring about the marking thereof. A group of components marked in this way, a corresponding container for carrying out the method, and a rolling bearing, which is a possible component to be marked in this way, are also disclosed. As a result, the self-organization and marking of a group of components is achieved with the help of an interconnected network.

Abstract: The present invention relates to a process for reducing the concentration of organometallic and/or inorganic by-products in product mixtures formed in the synthesis of metallocenes, which comprises treating a mixture comprising one or more metallocenes and one or more organometallic and/or inorganic by-products with a polar extractant.

Abstract: The invention relates to a method of coating red-luminescing phosphor particles with hematite (.alpha.--Fe.sub.2 O.sub.3), whereby first Fe(OH).sub.3 is deposited on the phosphor particles and subsequently converted into .alpha.--Fe.sub.2 O.sub.3 at a raised temperature. A good adhesion of the hematite pigments to the phosphor particles is achieved in that first an aqueous solution of an iron(III) salt and a complexing agent is prepared, in which the complexing agent and its concentration are so chosen that in combination with Fe.sup.3+ ions complex ions are formed which on the one hand do not yet precipitate at a pH-value which is at least 0.5 higher than the value at which the phosphor particles just fail to be chemically attacked anymore, and which are dissociable at a further increase in the pH-value so that Fe(OH).sub.3 is formed, in that subsequently, if the pH-value is not yet high enough, a basic substance is added to the mixture, in that the pH-value is increased to a value which is at least 0.
