Patent DE-4040150-A1 (DE)
Inventor: SCHMIDT FELIX DR
IPC: B01J37/02
Filed: 1990-12-15
Abstract: The invention relates to a method of uniformly coating honeycombs with finely divided solids from a dispersion in a quantity which is less than that arising in conventional dipping. For this purpose, the honeycomb is flooded from below with dispersion, and emptied after a holding time and blown out. The filling time, filling quantity, flooded holding time, emptying time and the time between emptying and blowing out are fixed at such values that, to increase the quantity of deposited solid, the filling time, holding time, pump-out time and the time between emptying and blowing out are increased but the filling quantity is decreased.

Title: Protective treatment for terracotta tiles - involves scrubbing with acid, washing with water, drying, and treating with impregnating fluid followed by polymer-wax dispersion
Inventor: DILLER HARALD
IPC: C04B41/52
Filed: 1990-12-22
Abstract: A process is claimed for the protective treatment of terracotta surfaces (I), pref. such as are laid inside buildings and left in a natural state, by applying an acid (II), allowing it to react and then removing it almost completely with water; the novelty is that the dry, cleaned surface is then treated with an impregnating fluid (III), followed by a polymer-enriched wax dispersion (IV).

In a material compsn. ratio of pullutants to the vitrifiable raw material mix plus additives is about 1:1 with 10% variation, the overall melt having a frit and/or cullet content of about 20%. USE/ADVANTAGE - Esp. useful for disposal of heavy metal laden filtered solid waste, e.g. filter dust from steelmaking and filter cake from special waste incineration. Can convert large amts. of noxious waste into a non-polluting prod. having a wide variety of uses e.g. in the building, chemical and electrical industries.

Title: Mobile container for roll-on-roll-off loading system - has rubber wheels, moving or locked in grooves in vehicle chassis, for loading or unloading via ramps
Inventor: SCHATTA MARTIN
IPC: B61D3/20
Filed: 1991-09-13
Abstract: The container (1) has rubber wheels (2), which roll in rubber-lined recesses (14) in chassis struts (13) to a certain depth. This ensures, that the container struts (15) almost engage on the chassis struts, so that they can be locked together by screws.

This permits un/loading via conventional ramps by traction vehicles, on all sites. Instead of struts, narrow- gauge rails may be used. Screw bolts in bores give optimum connection between chassis (5) and container, while the container remains standing on its wheels. ADVANTAGE  - Permits use of large containers on sites without cranes, etc.
