Abstract: A chip card includes a semiconductor chip that contains at least one memory. In order to supply energy to the chip and to provide for bi-directional data transmission from and to the chip, both contacts and a device for contactless data transmission are provided. A triggerable switch device which is provided on the chip connects the memory either to the contacts or to the device for contactless data transmission as a function of a state of an output signal of a logic circuit connected to at least a voltage supply contact. The switch device assumes a position of repose when it is not triggered and in that position it connects the memory to the device for contactless data transmission, while only upon application of a voltage to the supply voltage contact, triggered by the logic circuit, does it connect the contacts to the memory.

Abstract: A slurry containing water, carbonate-containing pigment, and dispersant consisting of 25-70 % by weight of agglomerated carbonate-containing pigment, 0.1-1.0% by weight of a dispersant, the balance being water up to 100%, can be used advantageously in papermaking as well as in the paint and lacquer industry. In a novel process for agglomerating ultra-fine particles in slurries the slurry is subjected to heat treatment until the agglomeration is complete.

Abstract: A device for processing and storing data, in particular a chip card, includes a first interface with contacts and a second contactless interface for receiving energy or power from and for communication with a terminal device. A first controllable switching device connects either the first or the second interface to a non-volatile semiconductor memory through address, data and control lines. A logic circuit drives the first controllable switching device. A second controllable switching device disposed between the first controllable switching device and the memory can be driven at least by the logic circuit and an address signal present on the address lines.

Abstract: Reaction spray process for preparing inclusion pigments by suspending the pigment to be encapsulated in an aqueous solution or suspension of a precursor of the inclusion material, spraying the suspension, with or without the addition of nitric acid and fuel, in a tubular reactor heated at from 850.degree. to 1100.degree. C., separating the inclusion pigment from the product stream and, if desired post-calcining the pigment at a temperature of at least 816.degree. C.

Abstract: A pigment composition containing one or more luster pigments, a phosphate derivative and spherical particles having a particle size of 0.05-150 .mu.m useful, especially, in printing inks.
