Abstract: Stable dry powders which are insoluble in hot water and which contain one or more lipid-soluble vitamins an/or one or more carotenoids are formed in an aqueous dispersion containing 2 to 50% by weight of at least one protein, 1 to 30% by weight of at least one sugar, 0.2 to 20% by weight of K2HPO4, Na2HPO4 or mixtures thereof, 0.1 to 20% by weight of at least one lipoid-soluble vitamin and/or at least one carotenoid and 5 to 95% of water. This dispersion is converted into dry powder which is heated in the range of 55° C. to 1800° C.

Abstract: A medical device which has a data generating unit and a data processing unit that can be displaced relative to each other, as well as an arrangement for transferring the data from the data generating unit to the data processing unit. The arrangement for transferring the data includes a hollow conductor and an antenna that works in conjunction with the hollow conductor, which are displaced relative to each other in a defined manner in the displacement of the data generating unit and the data processing unit relative to each other, and via which the data transfer is accomplished.

Abstract: An x-ray exposure apparatus is freely movable in space without a cable, and allows the electronic production of x-ray images at the bed of a patient. The apparatus includes a cart with an image receiver, such as an amorphous silicon-based solid state detector, to which an image memory on the cart is allocated. Power supply ensues by means of a rechargeable battery that is integrated into the cart.

Abstract: In a process for preparing dry, free-flowing choline chloride-containing powders by atomizing an aqueous choline chloride solution, a colloid-free aqueous choline chloride solution is atomized in a countercurrent-flowing air stream that contains, finely dispersed, a hydrophobic spraying auxiliary metered in in such amounts that the sprayed choline chloride droplets are coated with 2 to 15% by weight of spraying auxiliary, based on choline chloride calculated as 100%, and the coated particles are, if desired, collected in a fluidized bed and dried in the gas stream.

Abstract: Ascorbic acid 2-phosphate is prepared by reacting ascorbic acid or an ascorbic acid derivative with POCl.sub.3 in the presence of a tertiary amine in a suitable aqueous solvent at from -10.degree. to 25.degree. C. while maintaining a pH of about 8-13.5 with KOH during the entire phosphorylation reaction and then isolating the ascorbic acid 2-phosphate, by a process in which an aqueous solution of a magnesium compound is added to the reaction mixture obtained in the phosphorylation, without prior treatment with an ion exchanger, until the formation of crystalline KMg PO.sub.4 is complete, the KMgPO.sub.4 which is crystallized out is separated off, the resulting filtrate is evaporated down at a pH of from 6 to 11 and/or from 0.
