Abstract: Disclosure is made of a specific process for producing activated carbon in spherical form, starting with organic polymer spherules based on styrene and divinylbenzene, wherein said polymer spherules contain chemical groups leading to the formation of free radicals and thus to cross-linkages by their thermal decomposition, in particular sulfonic acid groups. Furthermore, various application purposes for the thus-produced activated carbon spherules are named.
Abstract: An odor filter for exhauster hoods, which filter includes an adsorption filter bed regenerable by washing. The filter bed is made of a highly air-permeable substrate material and an adsorbent affixed thereto in the amount of 50 to 400 g/l by an adhesive mass and has a mean particle diameter between 0.2 and 2 mm.
Abstract: The present invention relates to a process for the decontamination of chemical warfare agents which are present on the skin or have penetrated below the surface into the skin, or materials contaminated therewith, by a micro-emulsion which contains a C.sub.8 -C.sub.14 alkane, an anionic surfactant, an aliphatic C.sub.3 -C.sub.10 alcohol, and water, and to which possibly a wetting agent and/or antifreeze components such as antifreeze agents, NaCl or CaCl.sub.2 are also added.

Abstract: A seal-free and frame-free odor and/or pollutant filter, e.g., in air conditioners and motor vehicles, having a self-supporting and elastic adsorption filter bed installed under slight compression in air supply ducts. The filter bed is made of a highly air-permeable substrate material and an adsorbent affixed thereto by an adhesive mass.
