Abstract: An improvement for a turbocompressor having a rotor, a stator and a casing, and an abradable coating provided between the rotor blades and the casing, or between the stator vanes and the rotor, such that the blades make initial contact with the coating to abrade the coating and produce a minimal clearance. The abradable coating is formed on a member having a first layer of carbon-fiber reinforced graphite adapted for attaching the coating member to the casing or rotor, and a second layer of graphite in the region in which the blade tips are intended to rub. The second layer may optionally contain, preferably radially oriented brush-type graphite-fiber reinforcements, or be entirely composed thereof.

Abstract: Method and apparatus for manufacturing planar fiber webs from reinforcing fibers which are oriented in their passage through a hydrodynamic orientation section and deposited on a filter surface. In the process, the rotating orientation section produces a laminar flow pattern causing the reinforcing fibers in the slurry to be oriented. The filter surface is rotated, as is the orientation section, to hasten the extraction of the slurry liquid by filtration, to improve the degree of orientation of the fibers, and to fix the oriented fiber cake on the filter area. Extraction of the slurry liquid by filtration eliminates the need for washing or rewashing.
