Translation of "Luft zuführen" in English

The respiratory muscles need to supply the lungs with the required air under more difficult conditions.

You need to draw in fresh air and draw out the hot, stale air.

Give as much as possible fresh air to the cacti.

Several compressors can simultaneously supply air to the pressurized medium chambers or air can be withdrawn from the pressurized medium chambers.

A humidifier can add moisture to the air, which relieves the irritation in the nasal cavity.

The valve 16 is open in an unactuated condition in the illustrated position, that is to say the air outlet A is connected to P and the knocking device is loaded as soon as the air supply connection 30' can supply air.

On the other hand, there will be combustion air supply openings located considerably above the bed of embers and, according to the described mode of operation, no longer supply combustion air, yet are in a place suitable for the supply of secondary air.

Even the newest proposals (open German application Nos. 30 44 229, 31 23 886, 32 09 365) deal with various possible solutions for supplying the mangle with air.

The rear footwell/rear-defrosting air duct 70 R generally conducts hotter air than the rear-ventilating duct 72 R in order to be able to supply hotter air to the rear footwell and/or the rear window panes.

On the same representation are projected delivery apertures 7 and transfer apertures 17, which, when they overlap, supply air to one group 31 of relay system jets 3 in the double hatched region of the travelling field for axial sections 4.

In the Helmholtz-Resonator, through the elasticity of a larger volume of air, and together with the inertia of the air-column, one can achieve autonomic oscillations which supply more air to the individual cylinders.

In the enlargement you recognize three black plastic pipes which supply the air to the cylinder head above the fuel-distributor pipe.

Between the compressor 4 and the internal combustion engine 1 in addition a charge-air cooler 10 can be arranged, which cools the charge air provided for combustion in the internal combustion engine 1 and thereby can feed more air for each combustion process.

Activation of the primary valve and/or the secondary valve can take place for blowing off air or for delivering air to an air bellows.

The door frame contains a number of ventilating openings, both in the lower as well as the upper holding strip, so that the air heated in the space between the panes can move by convection and supply the operating space with warm air.

Swirl generators 37 are disposed in the air supply duct 35, to swirl the air flowing toward the combustion chamber 13 .

Provide fresh air not only on the day to the cacti (above all during very warm weather) but also at night.

A small group of plants with large leaf surfaces, such as the African calla lily, can suck up water at a prodigious rate - about 1,000 gallons per day, depending on sunlight - and release it into the air through evapotranpiration.

Under ideal ventilation of the mattress due to the airvent function of Feeling- Air cushions, which make active fresh air the mattress.

At the same time the air is filtered before leading to the object to be enveloped.

Ionization of the air is an ENVIRONMENTAL FRIENDLY technology to clean the air without adding any chemicals.

Air intake is used for burning and the fireplace only warms up air in the room in circulatory way.

Hydraulic linking is easier but there is a risk of causing ruptures in the walls of the seam and provoking swelling problems, which would make things very difficult if an attempt was made to circulate air instead of water in order to effect oxidation.

I have found that this object is achieved, according to the invention, and other advantages are attained, by a process for the thermal decoking of cracked gas coolers for the indirect cooling, by means of water, of ethylene-containing cracked gases which are obtained by thermal cracking of hydrocarbons in the presence of steam in an indirectly heated tube cracking furnace, at cracked gas exit temperatures of above 750° C., wherein, instead of a heated steam/air mixture, heated air, without introduction of steam, is passed through the cracked gas cooler tubes which are to be decoked.

Using the process according to the invention, the cracked gas cooler is thermally decoked by passing heated air, without added steam, through it.

When using the arrangement described under clean room conditions it is not absolutely essential to use pure air but filtered air can be supplied instead.

Comparison Example In the attempt to condition the "peeled" product in an apparatus according to U.S. Pat. No. 4,089,119, FIG. 7, the air being introduced via the feed (there: 19) and the sesame grain via the feed (there: 3), a product is obtained having a residual moisture content of only 4%.

The blast-material air supply is then connected and the pressure of the air entraining the blast material increased until the initially rod-shaped jet leaving the exit nozzle becomes white and assumes the form of a cone.

This can be industrially exploited by sucking the air from the supply 4 by means of an ejector 12 by the stream of steam.

The mode of operation of said multiple cyclone is not described here in detail, i.e., the dividing of the air, the spiral-like feeding of the air into the cyclones, the depth of the immersion pipes referred to as the exhaust conduit and the like, because said details are basically prior art.

If necessary, the glass in the vessel can be cooled by blowing air into the vessel via an inlet port 33 (see FIG. 16).
