Translation of "Schadgas" in English

However, silicone-containing products accelerate the degradation of indigo by harmful gas.

The harmful gas causes irritation to the calves’ sensitive mucous membranes, thus opening ideal routes of entry for infectious agents.

Carbon monoxide is a combustion gas (harmful gas) that is released when combustion processes are incomplete.

The quantity of water is regulated by a control system, which is symbolically shown by a dashed line extending from the temperature control device 10 to the valve 10. This water quantity is so regulated that the temperature of the waste gases in discharge conduit 9 is maintained constant above a dew point, for example 105 degrees C. Noxious gases or pollutants contained in the waste gases, for example as SO2, react in the intermediate portion of the absorber first with dry particles of the neutralizing agent.

Elasthanes essentially have to be stabilized against light and noxious gases and for this reason contain stabilizers which are either introduced as additives to the spinning solution or incorporated into the segmented polyurethane.

Moreover, the circuit system must often be protected from noxious gas; with the known lacquer system such protection can only be obtained by using costly multiple coatings.

In the production of elasthane threads by solution spinning of polyurea polyurethanes by conventional spinning processes, excellent stabilization against light and noxious gases are obtained if at least one component of the system to be spun contains tertiary amino groups and the substances used as antioxidizing agents are phenols of the kind which do not form colored nitro compounds.

As the level of NO emission of an engine hardly rises at. all ? a result of a deterioration in the combustion process, a'nd as the average value for NO emissions falls to almost l/4'of the threshold value under full load and at rated speed during ope­rational use, an additional safety factor can safely be dispens with for this particular noxious gas.

High priority problems still remain to be solved with respect to the heavy metal contaminants Hg, Cd, Pb, Sb, Sn, and Zn, as well as others contained in the flue ash, the flue gas and/or the slag from the refuse incineration system.

Beyond that, with the known lacquer systems, additional permanent protection of the circuit surface (which is often sensitive to damaging gases) can only be achieved through elaborate multiple coating processes.

In order to get this harmful gas under control, the present invention provides that, together with the Ca(OH)2 which may also contain CaCl2, hartshorn salt, primarily NH4 HCO3, and/or baking soda (NaHCO3), and/or similar compounds, are admixed with the Ca(OH)2. Alternatively, the aforementioned hydrocarbonates, which are not stable and disintegrate into component parts at temperatures from 30° C. to 400° C., may be entirely substituted for the Ca(OH)2 adsorbent.

The polluting gas NOx is almost entirely transformed into the natural components nitrogen and hydrogen through selective catalyzed reduction (SCR) additives separated from ammonia, like urea.

We offer highly secure, press-fit connections between contacts and PCB holes – connections capable of resisting shock, vibration, extreme temperatures, and corrosive gases.

This double contacting approach guarantees reliable, gas-tight contacting in industrial environments and is resistant to external influences such as: shock, vibrations, thermocycles, corrosive gases, etc.Contacting on the roller surface with high-quality finishing guarantees at least 500 mating cycles and reduces abrasion of the surface when exposed to micro-movements.

In Central Europe tropospheric ozone is likely to be the most important gaseous air pollutant in recent years.

When a concentration of 400 ppm is reached in the security entrance, the filter unit removes 4 L/minute of toxic gas from the air.

The apparatus as defined in claim 17, wherein a regeneration unit for a 3-stage desorption process, in which pollutant-loaded active coke is initially guided from said moving bed reactor of a vertically extended regeneration unit from above through an indirectly heated desorber, and subsequently is conducted from above through a post-degassing zone, with suctioning-off of desorbed polluting gas, and finally, from above, through an indirectly cooled cooler.

To prevent ammonia, which is also a noxious gas, from being released into the atmosphere in such a process, the exhaust gas resulting from e.) is passed through an ammonia-oxidizing catalyst under conditions effective for at least partially oxidizing ammonia to nitrogen.

However, it must be borne in mind here in particular that objects and processes which generate particles and noxiant gas are eliminated in the cleanroom.

It is the objective of the invention, in particular, to provide a generic redox device which avoids accumulation of harmful gas, in particular a hydrogen/oxygen gas mixture, without a flushing process.

The measured signal S 35 shows at the time t 0 410 a base signal, which represents the absence of test gas or harmful gas.

Another object is the provision of such an improved electrical connector assembly that overcomes the above-given disadvantages, in particular that is adapted for motor-vehicle use and that simultaneously enables low longitudinal insertion forces and high transverse contact forces, and meets the most demanding requirements such as vibration, temperature, harmful gases, and media resistance, as well as ease of assembly for mass production.

In the case of the T 90 values, values in the range of 430-450° C. according to the pollutant gas were determined for the inventive catalyst #2.

The longer jeanswear is exposed to the action of harmful gas, the greater the probability of the development of irreparable lightening and yellowing.

Y series motors are widely used in many places, where do not exist combustible, explosive or corrosive gas, without any special requirements, such as machine tools, pumps, fans, transport machinery, mixer, agriculture machinery and food machines etc.

This product should not be installed in places such as outdoors ,humid and corrosive gas and so on.

Dürr has developed new, highly efficient and, above all, future-proof solutions for the treatment of harmful, solvent-laden, or odor-intensive emissions.
