摘要:
A process for the pyrolysis of refuse of all kinds wherein the refuse is subjected to carbonization to produce solid residues and raw carbonization gases, the residues and gases are separated, the gases are divided into two parts, one part of the gases is completely burned to produce hot flue gases, the flue gases are mixed with the second part of the raw carbonization gases, the mixture of gases is cracked in a reactor, and the cracked gases are cooled.
摘要:
The emission of halogens and sulfur dioxide and the formation of water-soluble compounds of heavy metals are suppressed in the pyrolysis of waste in a carbonization zone at a temperature in the range from 300.degree. to 600.degree. C. by adding a fine-grained basic material to the waste prior to completion of the pyrolysis of the waste in the carbonization zone.

Electrolyte materials for use in electrochemical cells, electrochemical cells comprising the same, and methods of making such materials and cells, are generally described. In some embodiments, the materials, processes, and uses described herein relate to electrochemical cells comprising sulfur and lithium such as, for example, lithium sulfur batteries. The electrolyte can comprise a polymeric material and, in some cases, an absorbed auxiliary material. For example, the electrolyte material can be capable of forming a gel, and the auxiliary material can comprise an electrolyte solvent. In some instances, the electrolyte material can comprise at least one organic (co)polymer selected from polyethersulfones, polyvinylalcohols (PVOH) and branched polyimides (HPI). The non-fluid material in the electrolyte, when configured for use, can, alone or in combination with the optional absorbed auxiliary material, have a yield strength greater than that of lithium metal, in some embodiments.
摘要:
A data carrier printed by line intaglio having a halftone image represented by irregular line structures in the manner of an engraving. The line structures are superimposed at least partly by fine structures rendered in positive or negative representation. Methods are provided for generating and processing irregular line structures as digital image data on a computer following individual specifications by an operator. The line structures are transferred to a line intaglio printing plate. The digital image data is used for controlling an engraving apparatus. In the alternative, other printing processes may be involved wherein the digital image data is superimposed at least partly with fine structures rendered in positive or negative representation.

摘要:
A method for thawing frozen road culverts. The first step involves positioning an electrically conductive cable in a road culvert prior to an ice blockage occurring. A connection end of the electrically conductive cable is anchored in an accessible location. The second step involves connecting a power source to the connection end of the electrically conductive cable after an ice blockage of the road culvert has occurred and supplying power to the electrically conductive cable, such that energy generated by power flowing through the electrically conductive cable causes a flow path to be created through the ice blockage in the road culvert.
摘要:
A method is proposed for the desulphurization of sulphur-containing fuels in which the fuels are mixed with at least one solid basic additive and at least one metal in finely divided form, the mixture thus obtained subjected to a pyrolysis and the sulphur adsorptively or chemically bonded to the basic additive separated by methods known per se. The method is particularly suitable for the desulphurization of heavy fuel oil or used oil, and as solid basic additive preferably lime and as metal preferably iron powder are used. The permanent gas forming in the pyrolysis and the simultaneously forming condensate may be directly fired as low-sulphur fuel.
摘要:
A corner deviating device for a locking bar brace supported in a casement frame of window or a door has a one-piece housing which is provided in a corner region with a mounting opening for a spring band having drivers at its ends, the mounting opening being closable by an angular cover. One leg of the housing is insertable into a receiving groove of one wing of the casement frame, while the other leg of the housing is fixable on an edge strip of an associated receiving groove of another wing of the frame.
