Abstract: Complexes in powder form of iodine and a crosslinked polymer based on N-vinyl compounds are obtainable by dry heating of iodine and a polymer which is obtained by polymerization of monovinyl compounds (monomers A) whose vinyl group is bonded to a nitrogen atom of a nitrogen-containing heterocycle, in the presence of from 0.5 to 10% by weight, based on the monomers (A), of a compound (B) of the formula I; where A is —CH— or a nitrogen atom, and n is 2 or 3. The complexes are suitable for producing antidiarrheals.

Abstract: A process brings out a high contrast in natural grain of a naturally pale wood via infrared irradiation having a wavelength which is as long as possible. This infrared radiation can come from a conventional infrared emitter or, more preferably, from a carbon dioxide laser. Due to the contact-free heating near the surface which is effective in a stagnant ambient atmosphere, the new wood part of the grain is browned, while the harder old wood part remains essentially unbrowned. This causes the natural grain of the wood to stand out in contrast. Due to the contact-free and turbulence-free mode of operation of the heating, the grain pattern produced is uniform. Any scratches or chatter marks in the wood are simply covered over and remain invisible.

Abstract: Direct tableting auxiliaries essentially consists of(A) from 88 to 96% by weight of pulverulent carrier conventionally used for the preparation of tablets and consisting of lactose, or lactose together with not more than the same amount of another carrier,(B) from 2 to 6% by weight of polyvinylpyrrolidone having a K value of from 20 to 40, and(C) from 2 to 10% by weight of crosslinked, insoluble polyvinylpyrrolidone, all percentages being based on the direct tableting auxiliary, and are obtained by spray drying, spray granulation or wet granulation.The novel direct tableting auxiliaries exhibit good flow and good compressibility under low pressure, and the tablets produced using the said auxiliaries possess excellent disintegration properties coupled with great hardness and low abrasion.
