  • Patent number: 5743940
    Abstract: A process for producing a fabric absorbent that is capable of efficient removal of odorous substances, in particular malodorous substances. The absorbent is obtained by exposing an organic high-molecular weight compound, such as polyolefinic polymers or halogenated polyolefinic polymers, to an ionizing radiation and thereafter graft polymerizing the high-molecular weight compound with a polymerizable monomer that contains ion-exchange groups and/or a polymerizable monomer that can be converted to ion-exchange groups so as to incorporate the ion-exchange groups in the high-molecular weight compound.

  • Patent number: 4110596
    Abstract: The apparatus for transporting and collecting self-propelled carriages for carrying out fillet welding of a construction in the rectangular form has carriages adapted to move along rails extending in the longitudinal direction which rails are in turn movable in the transverse direction, extension ladders each suspended by the respective carriages through rotating means so as to be rotatable about its longitudinal axis, clamp jaws each supported by the respective extension ladders. The clamp jaws are adapted to releasably clamp the respective self-propelled carriages so that the carriages are lifted and swivelled to assume orientation required for the fillet welding in the desired direction and again lowered and released from the clamp jaws thereby permitting the fillet welding of a construction in the rectangular form in different regions.
