The use of a plastic foam system, which contains at least one filler capable of swelling in the presence of water, for sealing openings in buildings, which are in contact with the outside, especially wall, floor and ceiling channels of pipes and/or cables.

Use of plastic foams containing swellable fillers for sealing wall channels

For sealing an annular space ( ) between opening ( ) in a wall or similar, member ( ) and an object ( ), extending through the opening ( ), by introducing a sealing agent into the space ( ), at least one bag ( ), into which the sealing agent is introduced, is positioned in the space ( ). For this purpose, a supporting element ( ) is used, which can be positioned in the opening and to which a bag ( ) is fastened. The annular space ( ) can be sealed easily and also liquid-tight in this manner.

Method and apparatus for sealing a space

A method of and a device for sealing a gap ( ) between a leadthrough ( ) arranged in a constructional element ( ) and an object ( ) extending through the leadthrough ( ), according to which an elastic sealing element ( ) which surrounds the object ( ) is placed in the gap ( ) and is compressed in an axial direction of the leadthrough ( ) and is fixed in its compressed condition with a fastening element ( ).

Method of and device for sealing a gap

A method for sealing a gap ( ) between a leadthrough ( ) provided in a constructional element ( ) and an object ( ) extending through the leadthrough ( ), the method including placing in the gap ( ) a plurality of elongate sealing elements, formed as hot melt elements ( ) provided with heat-activated blowing agent, and applying heat to the hot melt element from outside; and a sealing element used by the method.

Method of and a sealing element for sealing a gap

For sealing an annular space or space ( ) between an opening ( ), in a wall or similar member ( ), and an object ( ) extending through the opening ( ), at least one sealing element ( ) is placed in the annular space ( ). Initially, the sealing element ( ) is placed in the compressed state between the wall ( ) and the object ( ) and subsequently is released from the compressed state to an expanded state. For this purpose at first, the sealing element ( ) is compressed by a sheath ( ) which, after the sealing element ( ) is positioned in the annular space ( ), is destroyed and makes the expansion of the sealing element ( ) possible.

A valve arrangement ( ) for use in a container for discharging a fluid medium maintained under pressure in the container, particularly a cylindrical container. The valve arrangement includes a pot-shaped valve disk ( ) to be secured in an open side of the container. The valve disk ( ) has a coupling device ( ) for connection to a container adapter of a discharging device. The valve disk ( ) has a discharging valve ( ) including a valve piston ( ) and a restoring device ( ). The pot-shaped disk valve ( ) is formed of a plastics material with a plastically deformable and especially clinchable cylindrical pot wall ( ). The coupling device ( ) is an integral part of the valve disk ( ) and is joined by thin cross sections ( ) with the pot wall ( ).
