In a method for the combustion of a fuel, a fuel or a premixed combustible mixture is introduced into a combustion space as a combustible fluid open jet. The velocity of the open jet is selected in such a way that it is impossible for a stable flame front to form, i.e. is in any event greater than the flame front velocity, and that, on account of a jet pump effect, flue gas is mixed into the combustible fluid jet from the combustion chamber in a jet-induced recirculation internally within the combustion chamber. The admixed flue gas dilutes and heats the combustible fluid. The heating causes the spontaneous ignition temperature to be exceeded, and a low-pollutant volumetric flame is formed in a highly dilute atmosphere.

A high-voltage circuit breaker includes two arcing contacts, which are capable of moving relative to one another along an axis, an insulating nozzle, a heating volume for accommodating quenching gas, a heating channel, and an overpressure valve. The pressure of the quenching gas is based on the energy of a switching arc, which is formed when the breaker opens and generates arcing gas, and the heating channel opens out, with axial alignment, into the heating volume. The heating channel connects an arc zone, and the overpressure valve limits the pressure of the quenching gas by opening a relief duct, which opens out into an expansion space. In high-current switching, the pressure of the arcing gases in the arc zone is limited, and the quality of the quenching gas stored in the heating volume is improved, due to the relief duct having an outflow section extending in the radial direction.

The invention is related to a thermally insulated and moisture-repellent textile structure, consisting of 1. an inner layer (contact skin): made of moisture-absorbance and sweat-repellant ultrafine fiber; 2. a middle layer: made of thermally insulated and anti-static metal yarns combined with moisture-absorbant and sweat-repellent ultrafine fibers; 3. an outer layer: moisture-absorbant and breathable pure cotton. When such textiles are applied to apparels like underwears, sweaters or jackets, the ultrafine fibers in the inner layer can completely absorb excessive water molecules on skin surface. When these water molecules that carry body heat pass through the middle layer, through the dual functions of the metal yarns of thermal insulation and the ultrafine fibers of moisture absorbance and sweat repellency, the water molecules are completely absorbed by the outer layer of pure cotton and repelled from the body. The body heat is conserved between the middle layer and human body. Thus, when such textile is worn, besides the anti-static and anti-bacteria property of the metal yarns, body dryness and comfort can be kept at a constant body temperature. It greatly improves the textile in the effect of moisture-absorbance and sweat-repellency and thermal insulation.

Method for producing a porous titanium material for example a support. Starting from a titanium powder this powder is sintered under vacuum conditions in an inert / reducing atmosphere.
