Abstract: A method for the production of a microcapsule, in particular a microcapsule of spherical shape having a hollow capsule space therein, includes the steps of: a) preparing of a suspension of particulate cementitious material in a solvent b) preparing a dispersion by mixing the suspension of step a) with an immiscible fluid so that (i) the suspension is present as a dispersed phase in the fluid as a dispersion medium or that (ii) the fluid is present as the dispersed phase in the suspension as the dispersion medium, such that the particulate material of the suspension adsorbs at least partially at a phase boundary between the fluid and the suspension, and c) allowing the particulate material adsorbed at the phase boundary to hydrate with the formation of a microcapsule.

Abstract: A method for detecting straightness deviations and/deformations in a rotary kiln, the rotary drum of which features bearing rings spaced apart from one another in the axial direction and respectively supported on rollers, the outer surface area of the rotary drum, the bearing rings, involves scanning the rollers and/or the shafts of the rollers in a contactless fashion with the aid of at least one scanning device and obtaining three-dimensional position data regarding the scanned object(s), and evaluating three-dimensional position data with respect to the occurrence of a deviation of (a) the rotary kiln axis from a straight line, (b) the rotary drum from a cylindrical shape and/or (c) the rotational axes of the rollers from a line extending parallel to the rotary kiln axis. A device for detecting straightness deviations and/or deformations in a rotary kiln, at least one scanning device and a rotary kiln so equipped are provided.
