Patent DE-3422202-A1 (DE)
Title: Process for catalytic gasification
Inventor: HUETTINGER KLAUS J PROF DR
IPC: C10J3/00
Filed: 1984-06-15
Abstract: The catalytic gasification of coals or cokes or carbon-containing materials of the widest provenance and composition, preferably by steam, is currently still in the development stage. Industrial introduction has hitherto failed because of the costs of the raw materials such as potassium carbonate used for the potassium preferred for the development of catalytic activity at low temperatures, which costs result both because of the specific price of the potassium carbonate and also because of the high catalyst requirement of potassium carbonate of up to 30%. In contrast, it has been found that by the use of certain raw materials or raw material mixtures which contain the alkali metals potassium and/or sodium in the form of non-readily degradable and reducible compounds such as chlorides and sulphates, a catalytic activity comparable to the carbonates can be achieved. However, the decisive advantage of the salts or salt mixtures underlying the invention lies in that the main components are available almost without restriction as minerals and can be used as such directly or after simple redissolution processes, that is, are available particularly inexpensively. Certain additives are available as by-products of the chemical and metallurgical industry.

Title: Circuit arrangement for the line feed of ancillary devices of a telephone set
Inventor: LANGE HEINZ DIPL ING
IPC: H04M19/08
Filed: 1985-01-30
Abstract: For the line feed of ancillary devices of a telephone set, a shunt arm is inserted between the speech wires which shunt arm is formed by a reactance stage with a constant resistance characteristic. The reactance stage comprises, inter alia, a capacitor which is charged up once the operating voltage has been applied to the reactance stage. Until the reactance stage has attained its charged condition, a period of time elapses such that the desired electric response of the reactance stage is set only when the capacitor is in the charged condition. To reduce this charging time, the capacitor is charged directly via either a Zener diode or a switch monitoring the operating voltage of the ancillary device.

Title: Process and apparatus for the multi-stage combustion of fossil fuels
Inventor: RADKE DIETRICH DR ING
IPC: B03C3/51
Filed: 1986-01-08
Abstract: In order to increase the efficiency of fossil-fuelled combined heat and power stations with the guarantee that the metallic materials are substantially protected from corrosion, a process is proposed in which, in a first stage, the gases are (partially) burnt to give CO- and H2-rich reducing gases and immediately after this, without intermediate cooling, are freed from the gas constituents and dusts at temperatures of 700 DEG C to 1000 DEG C with conversion of the heat removed for temperature control into steam and the purified gases are burnt in the gas turbine. For this, it is advisable to use an apparatus having, successively downstream of each other, a coal gasifier (3), reactor and gas-solids separation device (5) and further purification circuit (8), composed of filter bags, having an after burning circuit (11). Coal gasifier (3), separation device (5) and after burning circuit (11) are connected by shared heating surfaces (15) which serve for the evaporation of liquids which can be fed to a steam turbine unit (18).   <IMAGE>
