Patent DE-4141972-A1 (DE)
Inventor: VOGT WERNER
IPC: B30B15/34
Filed: 1991-12-19
Abstract: For laminating layers consisting at least in part of thermoplastic films, in particular in the production of information-carrying and/or data-carrying identification cards and the like, it is proposed, first of all, to exert on the blank inserted between press plungers the pressure and heat necessary for complete lamination and simultaneously, during this heating phase, to prevent a removal of heat in that cooling components (21) are kept at a predetermined distance (A), whereupon subsequently, during the transition from the heating phase to the cooling phase, the heating effect is switched off and only then are the cooling bodies moved against the pressing and heating components in order to reduce the temperature of the finished laminated product. <IMAGE>

Title: Method for regenerating water-glass-bonded used foundry sands
Inventor: HIERY HERMANN
IPC: B22C5/02
Filed: 1993-02-26
Abstract: In the foundry, waterglass is employed as moulding-material binder which, after the moulding, is cured by gassing with acidic gases. Foundry sands of this type can generally be used only once and must be disposed of after the casting process. The new method is to enable the foundry sand to be treated in such a way that it can be reused without restriction. The water-glass-bonded foundry sand is heated after destruction of the sand lumps in a furnace (4) to a temperature exceeding 200 DEG C, as a result of which the troublesome constituents are destroyed or converted, so that there is no disadvantageous influence on a further moulding process. Subsequently, the sand is cooled to processing temperature in a cooler (5). <IMAGE>
