Abstract: A kit of components a structure consists of a basic element (3) consisting, in the form of a hollow structural section like a cellular space with a rectangular cross-section, of two parallel side walls (1a) and of a floor slab (1b) and roof slab (1c), leaving two openings (3b), of a two-part folding door (6) that can be set into one of the two opening to constitute a front element, that can be fitted against each vertical side of the opening, and that consists at least partly of light-permeable material, each part of which has at least two wings that can be swung around axes parallel to the vertical front side, whereby the folding door (6) does not when it is open and folded back toward the two vertical front sides extend into the interior of the cellular space.

Abstract: An aqueous bath is disclosed for the galvanic deposition of uniformly rose to violet colored gold alloys and containing an alkali- or ammonium-dicyanoaurate-I, alkali copper cyanide, alkali cyanide and a bismuth compound which is a water-soluble complex compound of bismuth. Also disclosed is a method for the galvanic deposition of the alloys and employing the particular bath.
