Abstract: An installation for hot dip coating a metal strip is provided. The installation includes a device for moving the metal strip along a path, a pot for containing a melt bath and a wiping system including at least two nozzles placed on either side of the path downstream the pot. The wiping system has a box with a lower confinement part confining an atmosphere around the metal strip upstream of said nozzles and an upper confinement part confining the atmosphere around the metal strip downstream of the nozzles, first moving means for vertically moving the lower confinement part with respect to the pot and second moving means for vertically moving the upper confinement part with respect to both the pot and the lower confinement part. The nozzles are vertically movable relative to the pot.

Abstract: A type of tomography is described, wherein occupancy of lattice sites in a microscopic sample of crystalline material is predicted. An electron beam is projected through the sample, at a specific angle, causing discernible spots in a detector, such as photographic film. Each spot corresponds to a row of atoms. The intensity of each spot indicates the number of atoms in the row, and the number is called a "line count." Projecting the electron beam at specific additional angles produces additional line counts. From all the line counts, a set of equations is derived. Each variable in the equations corresponds to a lattice site in the material. A solution to the equations is found by linear programming techniques, thus assigning a value to each variable. Each value indicates the probability of occupancy of a respective lattice site.
