Patent DE-19730385-A1 (DE)
Title: Generation of fuel- and synthesis gas from domestic waste char
Inventor: SCHINGNITZ MANFRED DR
IPC: C10J3/66
Filed: 1997-07-16
Abstract: The process generates fuel and synthesis gas from pyrolysis (3) products by gasification in suspension. The gasification unit combines combustion (15) and gasification (17) stages. Mineral components of fuel and residual waste matter are fused in the combustion stage, flow down a cooling screen and are granulated in a water bath (22), to a glass-like product (23). This resists leaching in the environment. The combustion stage is fired to slagging temperatures, with a feed of pyrolysis char (11) and air, or alternatively oxygen and steam. Conditions are oxidising and temperatures exceed the m. pt. of mineral components in the solid pyrolysis products. The gasification stage is above the combustion stage. Pyrolysis- and fluid products are mixed with flue gas from the combustion stage, with further addition of gasifying medium, e.g. air, or oxygen and steam if necessary. Gasification temperatures lie below the melting point of pyrolysis pro ducts, under reducing conditions. In accordance with calorific value and mass distribution of individual pyrolysis products, and as a function of the exothermal liberation during combustion, compared with the endothermal consumption in gasification, to maintain the necessary temperatures in both stages, the fluid products are supplied in part or entirely to the combustion stage, and there, with further air or oxygen/steam, they are burned to form the gasification medium.

Patent DE-19753728-A1 (DE)
Inventor: NITZSCHKE RUEDIGER
IPC: F16H63/32
Filed: 1997-12-04
Abstract: The invention relates to a 12-speed gearbox for utility vehicles with a 2x3x2 construction. The shift lever (1) is configured as a universal joint with a shift fork (2) and a reversing lever (3). Said shift fork is arranged in such a way that it pivots jointly with the gearbox, whilst the reverse lever (3) is mounted on the shift fork in such a way that it can pivot. When the shift fork is operated, the synchronising movement which occurs upon engagement in a synchronisation mechanism runs in an opposite direction. When the reverse lever is shifted, the movement is in the same direction. This makes it possible to shift through the six speeds of the main gearbox in one stroke with successive shift movements in opposite direction.
