Title: Wall panels of thermally insulating and fire resistant material - have grooves and ridges along their edges to form overlapping edges
IPC: E04C2/292
Filed: 1990-08-28
Abstract: A wall is constructed from rectangular panels made from thermally insulating and/or fire resistant material. Each panel has longitudinal ribs and grooves formed on two opposite edges so that when two panesl are placed side by side the ridges of each panel fit into the grooves of the other panel.

Title: Coating metal with thin corrosion-inhibiting lubricating film of thiol - by directing gas phase produced by heating liq. or solid thiol and depositing on surface by adsorption
Inventor: KARTLUEKE DIETER DIPL ING
IPC: C10M105/72
Filed: 1990-09-26
Abstract: In the application of a thin, corrosion-inhibiting, lubricating thiol (IA) or thioether (IB) coating to metal surfaces, (a) a gas phase produced by heating liq. or solid (I) is directed onto the surface; and (b) (I) is deposited on the surface by adsorption. Pref. (I) have long fatty acid gps. with unbranched C chains, pref. with 14-20 C. The metal pref. is Ag, Cu, or their alloys. The gas phase is produced by heating (I) to up to 150 deg.C and may be mixed with air or inert or reducing gases. USE/ADVANTAGE - The process is very simple and avoids the use of solvents, which can pollute the working area and environment. Non-metallic surfaces, e.g. plastics, remain uncoated, since they do not adsorb (I). The process is esp. useful for making sliding contacts and plug contacts. The coefft. of friction of the coated surface is reduced to 1/3rd of the value for the untreated coating. In addn., the formation of sulphide on Ag is greatly reduced by coating with (IA)

Title: Continuously dewatering sludges - comprises collecting solids on vertical centrifuge bowl while liq. passes over rim and periodically opening or folding bowl to release solids
Inventor: KASTEN HEINZ
IPC: B01D43/00
Filed: 1991-02-02
Abstract: Device consists of a centrifugal system by which heavier components are pressed against the inner wall (3) of the bowl (1), and the filtrate is made to flow over its upper edge. The bowl is made of a flexible material (rubber, plastic etc.), and downwards movement of the finger elements (4) causes the wall (3) of the bowl to fold downwards, allowing the de-watered sludge (7) to leave the bowl under the effect of the centrifugal force.
