Translation of "Leichter unterdruck" in English

There is preferably a slight negative pressure inside the chamber.

A slight negative pressure is generated in the housing interior 33 .

This will create in the living area a slight vacuum.

This suction syringe is slightly drawn up so that a slight subpressure is created in the cannula.

To this end, because of the inherent resiliency of the PET material, a slight negative pressure must be applied to the feed side.

As there is constant slight low pressure during operation, this is not necessarily noticeable.

When burning the ear candle in the external auditory canal creates a slight negative pressure (chimney effect).

In this case, the danger exists that, on account of undefined flow conditions, pressure fluctuations occur and a slight depression temporarily comes about in the furnace interior, which would result in the penetration of secondary air into the furnace through the furnace door and/or the casting spout.

Depending on whether ink is applied to one or both sides of the sheet and depending further on the nature of the ink and stock used, a substantial or a small air cushion or a reduced or a considerable negative pressure can be produced on the guide surface.

A slight negative pressure is advantageously maintained in the entire processing- and conveying system when performing the method.

If at least one of the two containers is deformable, the deformable container can be compressed slightly before the plug connection is produced, forming a slight vacuum pressure for sucking or drawing a liquid out of the other container.

According to the previous state of the art--see German patent (DE-PS) 36 07 738--minor stone throw damage to laminated safety glass is repaired by generating a slight vacuum over the spot to be repaired by means of a suction cup and then, by means of a one way syringe, piercing the outer skin of the suction cup, which is homogeneous with respect to the wall thickness, in order to introduce the repair resin.

It is even possible to arrange the supplementary cam in such a manner that during the expansion stroke of the piston in the cylinder, a slight underpressure results.

The process according to the invention is expediently carrier out in such a way that burner flame gases of usual temperature, preferably between 50° C. and 2000° C., particularly preferably between 800° C. and 1500° C., and very particularly preferably from 1000° C. to 1500° C., that is to say flame gases and/or industrial waste gases at these temperatures, are introduced with turbulence in the form of bubbles into the absorbent liquid through a tube by means of an homogenizer, vibrator or rotor, the homogenizer, vibrator or rotor propeller being of such dimensions that a slightly reduced pressure is generated in the tube when the equipment is in operation.

Method according to claim 1, wherein a slight underpressure is maintained in the interior of the furnace.

In accordance with an additional advantageous embodiment of the invention associated therewith, the exhaust is suctioned off and an exhaust filter is disposed on the air outlet so that the entire exhaust is guided through the exhaust filter to effect a slight partial pressure within the building.

As a result of the air flow resistance through the first opening 9 into the vacuum chamber, a slight vacuum forms therein, whilst an inflow corresponding to the suction takes place through the opening 9, i.e. meeting the still closed edge of the pouch in the vicinity of the opening zone.

After the measured injection of the conductive paste 10 into the holes 5 in the circuit board 2, a slight vacuum is applied to the cartridge 23 and the cartridge needle 8 by the control unit 18, so that no more conductive paste can come out.

Prior to opening, by folding up at least one corner it is necessary to produce a slight vacuum, so that the container can be opened by tearing off a corner region without overflowing.

The brewing process may create a slight vacuum in the coffee brewing housing to an extent sufficient to prevent the coffee brewing housing from swiveling down out of the housing by gravity.

With the help of the suction opening it is possible to produce a slight negative pressure in the front portion so that surrounding tissue is slightly pulled towards the front end portion.

Together with the cover they form an evacuatable space 36 where, as a result of the sealing measures, a slight vacuum can be maintained.

The dust or respective spray cloud can be removed with an extraction tube or cannula introduced into the mouth, wherein a slight under-pressure or vacuum is provided in the patient's mouth at the same time.

In principle, only a slightly reduced pressure should prevail in the crankcase throughout the operating range, since, the greater the reduced pressure, the more oil is disadvantageously extracted together with the BB gas.

After all, the pressure inside this capsule is only the atmospheric pressure of the surrounding air or a slight partial vacuum if the capsule has been connected to an extraction system.

If the vein segment 5 is to be extended somewhat more in the radial direction, a slight vacuum may be formed in the space 17 by an additional syringe 28 which is attached to the end of the flow path 25 via the shut-off valve 27.

The embodiment wherein the gas from the space above the stored products, which is then passed through gas purifying equipment for binding and/or decomposing any hydrogen phosphide contained therein, is exhausted only at the end of fumigation, is not the only possible approach, one may also continuously withdraw gas and pass it through the purifying equipment during the entire fumigation period, thus creating a pressure slightly below atmospheric in the space directly above the stored products or within the storage facility itself, respectively.

In this way, a slight underpressure is produced in blow duct 19, whereby dust is prevented from leaving blow duct 19.
