Abstract:
The invention relates to a method for cascaded biomass oxidation in a dish burner with ejection firing. The fuel (18), together with oxygen-containing primary air, is fed to a gasifier dish (8) having high thermal conductivity, in which the fuel is gasified by pyrolysis in a first combustion step, the resulting gas is conducted through guiding devices (6, 9) over the dish edge (11) of the gasifier dish, or over recesses on the upper dish edge, to the outside wall of the dish (8), and is enriched with oxygen-containing secondary air in the intermediate chamber (10) and converted into a cyclone flow around the outer shell dish during a second combustion step, through the convection of which strong thermal feedback is created, together with the high reflection of the thermal radiation on the guiding devices.
Abstract:
A memory device is provided, the memory device having a memory cell, a programming unit for programming the memory cell, and a switching unit for optionally connecting or isolating a terminal of the memory cell to or from a potential which serves for altering an electrical property of the memory cell and for thereby effecting an altered programming state of the memory cell.

Abstract:
An electromechanical energy converter for a gaseous or vaporous medium comprising a stator (1) with two pot-shaped stator members (1a, 1b), each open at one end face and adjoining each other at these end faces, the stator members surrounding a working space (12) and forming a common magnetically permeated air gap (7) in which a coreless armature coil (25) is displaceably arranged. Arranged in the working space (12) is a freely oscillating piston (14) linked to the armature coil (25). Furthermore, at least one source (21a, 21b) for the medium, two reaction chambers (66a, 66b) each assigned to a head (15a, 15b) of the piston (14) and control means (17a, 19a, 22a, 23a; 17b, 19b, 22b, 23b) assigned to the reaction chambers (66a, 66b) for self-control of the piston oscillations are provided, by means of which the reaction chambers (66a, 66b) may be opened to the source (21a, 21b) during the piston oscillations for accepting medium under pressure, and to the working chamber (12) for releasing expanded medium (FIG. 11).
