Crosslinked (meth)acrylates with a particle size in the range from 0.001 to 10 mu m, which have a degree of swelling from 100 to 2000% by weight and a degree of crosslinking of from 50 to 100% by weight, based on the polymer, are fillers for dental applications.

Dental materials contain a filler which consists of polymeric crosslinked (meth)-acrylates having a particle size in the range from 0.001 to 100 mu m, a degree of swelling of 50 to 2,000% by weight and a degree of crosslinking of 1 to 100% by weight, (meth)-acrylic acid esters which form crosslinkages and no crosslinkages, and additives.

Each room has a separate input air unit and output air unit, or, alternatively, a common output air unit may be used for a number of rooms. Each group of rooms, e.g. apartment, has a unit which is fed with input air and distributes is separately to each room. This unit contains a heating element which can either be electrical or fed with waterborne heat. - The input and output air system contain o...

The invention relates to a method for the manufacture of a load-bearing structure and the load bearing structure itself. According to the invention this is manufactured by casting a frame part 13 and at least one bracket, that is fixed to the frame part. In the frame part 13 and the bracket, casings 8, 5 are arranged, the ends of which casings open out into the surfaces of the frame part and the b...
