Title: Starting of static-bed coal gasification reactors - from cold or when already ignited, by adjusting compsn. to steadily increase temp. and treating with steam
Inventor: DUERLICH MANFRED DIPL ING
IPC: C10J3/02
Filed: 1990-04-28
Abstract: This method of putting static-bed pressure gasification reactors into operation includes both the igniting procedure (from cold) and the starting of an already-lighted reactor. The igniting and starting gasification mediumm is varied in composition while the reactor is being put into operation. At first, the composition of this mixture is adjusted so that a steady temp. rise in the reactor is possible without an explosive gas mixture being able to form.  Next, after the charged reactor and crude-gas passages  have been inerted, the method includes treating the system with steam in the ignition process, or with N2 or CO2 in the starting process. A number of variants are claimed. USE/ADVANTAGE - Used for starting operation from cold or otherwise of coal pressure-gasification reactors in a more economical and environment- friendly way than hitherto, with, in partic.  freedom and harmful emissions.

Patent DE-4121027-A1 (DE)
Inventor: MAIER GERHARD
IPC: H03D9/06
Filed: 1991-06-26
Abstract: Known circuit boards having an oscillator and a modulator or demodulator are very costly, because the perturbing radiation emitted by the oscillator must be well screened off. In order to decouple the oscillator frequency, a transmitter was used that needed to be aligned in a precisely symmetrical manner. Besides such a balancing, such arrangements required a high number of mechanical components. In order to reduce these costs, the oscillating circuit of the oscillator is designed as a printed circuit with a printed inductive resistor connected to a capacitive diode, whereas the printed inductive resistor is coupled to an equally printed inductive resistor of the modulator. In the area of the oscillator and modulator, on the opposite side of the circuit board, is arranged a conductive surface connected to a reference potential and to conductive surfaces (14) arranged in the oscillator and modulator area on the other side of the circuit board by means of plated through holes. The invention is suitable for video recorders and stand-alone decoders (such as satellite receivers).
