Title: Braking system for forklift truck
Inventor: JOHN UWE DIPL ING
IPC: B62B5/04
Filed: 1990-03-15
Abstract: The forklift truck fork (40) is raised and lowered by a hydraulic cylinder (1). The pressure of the hydraulic field in the lower part (34) of the cylinder under the piston (35) is thus proportional to the load supported by the fork.  The road wheels of the truck are fitted with a brake formed by curved levers (3, 5), which press brake shoes against a disc (6). The levers are actuated by brake cylinders (24, 25) which are connected to the fork lifting cylinder so that the brake cylinder pressure is the same as that of the fork lifting cylinder. The braking force applied to the truck is thus proportional to the truck load.

Patent DE-4117444-A1 (DE)
Inventor: SCHNEIDER DIETMAR DR
IPC: C03B5/04
Filed: 1991-05-28
Abstract: The invention relates to the treatment of residues, such as grate ash, boiler ash and flydust from a waste incineration plant. It is known to collect the residues and to melt them in a melting furnace. In this case, however, metals and metal compounds remain in the slag produced, so that the re-utilisability of the latter is restricted. The invention is intended to improve the re-utilisability of the slag. A melt enriched in metals is additionally tapped from the melting furnace. A completely glassy slag which can be used, for example, in road construction is thus formed from the remainder of the melt. <IMAGE>
