Abstract: A filler for plastics or elastomeric materials comprising a powder having a ferromagnetic material content greater than 20% by weight and a silica content greater than 20% by weight, the powder being coated with an electro-conductive metallic material. The filler is designed to provide shielding for electromagnetic radiation.

Abstract: An arrangement for interconnecting wall panels of corresponding construction with one another to form walls of predetermined size and orientation is disclosed. The arrangement comprises a series of spaced apart parallel channels in the vertical sides of the wall panels; outwardly and upwardly extending fingers along each vertical side of each of the wall panels and positioned between the parallel channels; a columnar vertical standard which is received between the respective vertical sides of the adjoining wall panels and which column includes a plurality of spaced apart parallel vertical flanges which are of a size and spacing for being engagingly received in the channels; and parallel sets of vertical web members positioned at locations along the columnar standard which correspond to the location of the upwardly facing fingers along each vertical side of the adjoining wall panels.
