Title: Burning process
Inventor: SCHMIDT ADOLF
IPC: F23L15/00
Filed: 1993-04-02
Abstract: The invention relates to the flexible combustion of solid fuels of all types for energy production, as takes place in the utilisation of biological residual substances and the thermal utilisation of regenerating biomass raw materials. To develop a burning process for solid fuels which, while being highly efficient, can be easily controlled to meet the changing parameters of the biomass and produces waste gases laden only to a small extent with dust, the circulating bulk material and the solid fuel must pass through the burning zone together, during which heat is absorbed by the combustion waste gas, stored and subsequently conveyed to the supply air and it is thus possible to ensure stable ignition conditions.

Title: Method for controlling or regulating a vibratory compaction system for the compaction and moulding of moulding materials in moulding boxes and compaction system for applying the method
Inventor: BALD HUBERT
IPC: B28B3/02
Filed: 1994-09-28
Abstract: When a novel method is used for controlling or regulating a vibratory compaction system for the compaction of moulding materials by means of compacting impacts, that "free-flight travel" is observed which, when the moulding box and moulding material is lifted off from the impacting mass of the vibrating table, occurs until the renewed impact (see Fig. 2). The associated impact phase angle, which can be determined by means of appropriate sensors, is a parameter which is important, above all, for fixing the impact velocity and therefore also the impact acceleration. The impact phase angle is advantageously made the object of a regulating variable, and, in order to perform the regulating function, the influencing variable, which is the oscillation frequency and/or oscillation amplitude, is to be varied. Stone-moulding machines are the typical area of use.
