Abstract: Coating of solid particles in a fluidised bed by application of a gaseous coating agent from a plasma, wherein the plasma is generated outside the fluidised bed at a pressure of 0.01 to 500 mbar, and the plasma-activated gas is passed into the fluidised bed which is operated at a pressure of 0.1 to 500 mbar, where a. the plasma is generated from the total amount of gaseous coating agent with or without another gas, or b. the plasma is generated from a portion of the gaseous coating agent with or without another gas, and the remaining portion is introducd directly into the fluidised bed, or c. the plasma is generated from another gas, and the total amount of gaseous coating agent is introduced directly into the fluidised bed.

Abstract: A ferromagnetic material is based upon an exhange coupling mechanism in which a hard magnetic phase (1) and a soft magnetic phase (20 are combined. While hard magnetic materials have a high anisotropy and a relatively low magnetic saturation, the soft materials exhibit the opposite effect. By coupling the materials an optimum is achieved. The volume of the soft magentic material is selected to be greater than that of the hard magnetic material. After removing a magnetic field from the material the remnant field effect is such that MRev is greater than 2.5. The material is an alloy of REx.Fey.Bz.Vu.Siv, where REx is a rare erth material. USE/ADVANTAGE - High performance material for permanent magnets, broad band microwave absorbers, magnetic recording material.

Abstract: The invention relates to a process for producing magnetic recording media for perpendicular recording by coating, by means of a PVD process, a non-magnetic substrate with a cobalt-containing, ferromagnetic metal layer which has a magnetic anisotropy perpendicular to the plane of the coating, the temperature of the substrate being increased during the coating by means of external heating.

Abstract: Preparation of protected aldehydes and ketones of formulae (I) and (II) comprises addition of alcohols of formula (III) to acetylenes or allenes of formulae (IV) and (V) in the gas phase at elevated temperatures in the presence of a heterogeneous, X-ray amorphic zinc or cadmium silicates. The content of zinc or cadmium, calculated as the oxide, is 1-40 wt.%. The catalyst is prepared by bringing a zinc or cadmium salt and an organic acid (which decomposes at below 400 degrees C) into contact with amorphic silica. Formation of the catalyst takes place at 50-500 degrees C in the presence of an OH-containing compound selected from water, 1-10C alkanols, 2-6C diols or triols or 1-6C carboxylic acids. R1OH (III) (R)2C=C=C(R)2 (V) R1 = H or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic group or acyl (all optionally containing inert substituents); R = H or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic groups (which optionally join together to form rings); and m = 0 or 1.
