Title: Process for immobilising the sulphur present in lignite in the solid combustion residues, and lignite briquette
Inventor: TEGGERS JOHANNES DIPL PHYS DR
IPC: C10L9/10
Filed: 1983-05-26
Abstract: To reduce the sulphur dioxide emissions when lignite dust and lignite briquettes are burned, these are provided during the manufacture with a defined proportion of sulphur-binding substances, preferably CaO and/or MgO or compounds which release CaO and/or MgO at elevated temperatures, in such a way that, for use in small burning installations, sulphur-binding substances are added to the lignite and, if appropriate, the resulting mixture is ground or briquetted. The operator of such furnaces thus does not need to take any special measures for reducing the sulphur dioxide emission. In particular, it is not necessary to provide the furnace with additional devices for feeding sulphur-binding substances into the combustion chamber.

Title: Process and apparatus for the supply of metal into a metal melt
Inventor: ROGGEN ROLF
IPC: F27D3/14
Filed: 1983-08-05
Abstract: In a process for the supply of metal into a metal melt, especially for melting solid metal, for example metal scrap or dross granules, the metal melt is to be at least partially divided and each part set in a rotary motion contrary to the other part, so that at least two melt rollers arise, the mid-axes of which form an angle to each other. The metal is fed in at the place at which the two melt rollers meet. The melt rollers are produced by introducing the metal melt into two pipe sections, approximately at right angles to the mid-axis and approximately tangentially to the cross-section of these, these mid-axes including an angle, or by setting the melt in rotary motion in the pipe sections by electrodynamic forces. <IMAGE>

Title: Machine for cleaning heating rails on machines for producing or finishing chemical fibres
Inventor: KEGEL GERNOT
IPC: D02J13/00
Filed: 1984-01-13
Abstract: The invention relates to a machine which eliminates the deposits on the heating rails of machines for producing or finishing synthetic yarns, this being an operation which has to be carried out at regular intervals in order thereby to guarantee a uniform quality of the synthetic yarns passing through. The cleaning has hitherto been carried out manually and is therefore time-consuming, cost-intensive and of varying thoroughness. The object on which the invention is based is, therefore, to provide a machine, by means of which the cleaning of the heating rails can take place with the saving of time and thoroughly. The machine consists essentially of a guide rail, which is attached parallel to the heating rail by means of appropriate mountings, and of the cleaning unit positively guided on the guide rail. The cleaning unit itself consists of one or more brushes which are guided along with oscillating movements, by means of an automatic advance, on the heater surface to be cleaned. The pressing force of the brush on the heating-rail surface to be cleaned, the oscillating speed of the brush and the advance on the guide rail are continuously adjustable.
