摘要:
According to known methods, biomass is broken down under the action of water vapour via a carbon monoxide-hydrogen mixture (called synthesis gas) as an intermediate stage into hydrogen and carbon dioxide instead of being combusted directly to generate energy. Carbon dioxide is stored/sequestered and the hydrogen is used to generate energy. The transfer of bio-activity can also be effected within the same process by breaking down a mixture of biomass and fossil fuel (e.g. wood and coal) into carbon dioxide and hydrogen. The hydrogen is then reacted with half of the formed carbon dioxide to form methane and the remaining carbon dioxide is stored. The stored carbon dioxide and generated methane respectively comprise one half each of biological and fossil carbon. If the bio-activity of the stored biocarbon dioxide is transferred to the fossil carbon in methane, a corresponding mixture of wood and coal produces 100% biomethane. Here, too, up to 100% biomethane can be obtained from coal-wood mixtures. By adding the hydrogen obtained from excess electrical energy to the biocarbon, the bio-energy based on the biomass used is even quadrupled. For a traceable eco-balance with such mixtures, it is important to quantify the bio-proportion in the two “end products” stored carbon dioxide and generated methane. For this purpose, use is made e.g. of the radiocarbon (C14) method.
摘要:
The method and apparatus disclosed herein improve throughput conditions limited by multiplicative noise by determining precoder weights for each data stream communicated between a MIMO transmitter node and a MIMO receiver node. The precoder weights are determined based on information derived from non-precoded reference symbols to decrease the energy allocated to the dominant signal path relative to the energy allocated to the non-dominant signal paths.

A portable analytical device is provided for analysis of a component of a body fluid. A measuring facility within the device may carry out the analysis on a test element inserted therein. The test element may contain a reagent that reacts with a liquid sample of the body fluid when the test element is contacted thereby to produce a change that is characteristic of the analysis. A processor may process measuring values determined by the measuring facility to yield analytical measuring data taking into account calibration values. A standardized, wire-based computer interface may be provided on the analytical device via which the analytical device can be operated by a computer, the analytical measuring data can be transmitted from the analytical device to the computer, the analytical device can be supplied with electrical power by the computer, and the analytical device can provide software to be read-out by the computer.
摘要:
A propellant charge arrangement for barrel-weapons or ballistic drives comprises a conventional core charge having an ignition system and a consolidated propellant surrounding the core charge and having its own high electrical energy ignition system which can be controlled in a time-delayed manner after triggering the core charge ignition system. The structure and arrangement of the consolidated propellant and its ignition system are chosen such that, during combustion of the core charge, the consolidated propellant disintegrates into fragments of essentially uniform geometry in response to triggering of its associated ignition system, wherein the fragments are accelerated into the gas volume generated during combustion of the core charge.

The purification of high-melting organic products, such an anthraquinone and substituted anthraquinones, which is substantially free from lower-boiling impurities, by melting the product to be purified by heating, while mechanically conveying the same along a path with a screw conveyer, as for example, in a melting screw; degassing the melt at a reduced pressure in a column, as for example, at a pressure of 50 to 400 mm Hg; passing the degassed melt through a thin film evaporator at a reduced pressure of, for example, 5 to 250 mm Hg to evaporate the high-melting organic product and discharging the remaining high-boiling impurities and such impurities which are not capable of being distilled from the evaporator through a conically tapering sump, while mechanically scraping residue from the sump wall, preferably with the use of a rotating helical screw in the sump; the discharge from the sump being effected into and through an enclosed path at a rate sufficient to prevent liquid accumulating in the sump, while maintaining the central portion of the enclosed discharge path at a lower temperature than its end portion to form a crystal sludge in the central portion, which acts as a pressure seal; and solidifying and recovering the product discharging from the enclosed path. The enclosed path is preferably established through a screw-type pump which feeds into a crystallizing screw where the solidification takes place, the crystallizing screw being preferably maintained above the screw-type pump and is maintained filled with an amount of sump product which approximately corresponds to the amount of product in the sump take-off screw. The vapors produced in the thin film evaporator are passed via a heated rectifying column into a condenser, and a portion of the condensate is passed to the column as a reflux and another portion taken off and solidified in a crystallizing screw.

A mixture of dinitroanthraquinones of which at least 35% is 1,5-dinitroanthraquinone is dissolved at elevated temperature in a halogenated aromatic hydrocarbon, a carboxylic acid nitrile or a cyclic sulphone and is thereafter cooled selectively to precipitate substantially pure 1,5-dinitroanthraquinone. Preferred solvents are 1-chloronaphthalene, sulpholane and adipic acid dinitrile. The temperature of dissolution ranges from about 120.degree. C up to the boiling point and cooling is by about 10.degree. to 200.degree. C to a temperature not below about 0.degree. C.
