Abstract: A roof is assembled conventionally from cladding supported by purlins or girders extending between end walls of the building. The cladding can be metal. By providing a single structural spanning member, the requirement for girders or purlins is avoided and construction work is simplified. The usefulness of the structural spanning member is measured by the unsupported span that can be erected when the member is formed from sheeting material of stock width, conventionally with steel 1 or 1.2 meters, of a given thickness and rigidity. This member achieves the desired solution by a novel configuration in which the whole width of sheeting is utilized to form a single member having a top chord spaced from a bottom chord by a strengthened web, wherein pairs of chords of adjacent members nest to provide a single pitch of the roof.

Abstract: A mounting element is anchored in a hole of a support structure by use of a hardenable binder material. The latter is fed from a feeding device which has an outlet section insertable into the hole. The outlet section of the feeding device has a volume which corresponds to that of parts of the mounting element to be inserted into the hole. Thereby only enough binder material can enter the hole to anchor the mounting element so that the expulsion of excess binder material from the hole upon introduction of the mounting element is prevented. A ring-shaped member may be fitted onto the mounting element to center and fix the latter in the hole. The ring-shaped member may be inserted into the hole before or after injecting the hardenable binder material into the latter.

Abstract: The present invention provides a new method of obtaining energy without using fuels. Basically the device consists of a conveyor belt that contains a continuous arrangement of cells or pockets that are open in the outward direction perpendicular to it's motion.
