Title: Buoyancy system for ship's hull - consists of chambers filled with cork amidships to enable hull to float even when flooded
Inventor: ERDMANN WOLFHARD
IPC: B63B43/10
Filed: 1991-04-05
Abstract: The ship (1) has cork buoyancy chambers amidships. When seawater enters the ship, superstructure and top deck project from the water.

Title: Thermal spray cladding - has mechanical surface cleaning action before further layer is sprayed on workpiece surface
Inventor: ASCHBACHER ADOLF
IPC: C23C4/12
Filed: 1991-07-23
Abstract: In the thermal spray process, to apply a layer of material on a flat or curved surface of a workpiece, such as a calender or press roller for a papermaking machine, the sprayed surface is treated mechanically before a further layer is sprayed. The mechanical treatment polishes the surface, and also removes any sprayed material which has not bonded sufficiently or has built up into thickened zones at the edges, working together with an underpressure. The treatment removes any surface oxidisation before the next layer is sprayed on to the surface. ADVANTAGE - The sprayed layer applied continuously to the workpiece surface has an improved adhesion and the max.  homogenous density, while the jet(s) and/or the workpiece are moved in relation to each other.
