Abstract: Composite panels with high fire-proofing capacity have two outer layers and a core that features a core mixture containing aluminum hydroxide in compacted form, lightweight fillers, in some cases fine gained or splintery aluminum hydroxide, as desired magnesium hydroxide and polymer-based binding agents. The composite panels are suitable e.g. as facade panels for building constructions.

Abstract: Wherever large forces have to be applied over short distances it is useful to employ a force multiplier device. Very large transmission ratios are, according to the present invention, obtained by interruption of the axis of rotation (2) and insertion of an only slightly displaced force transmission axis (4). The force transmission axis (4) can be continuously displaced to both sides of the axis of rotation (2) by means of positioning facilities, preferable an adjusting screw (5) or two wedges. This way variable force generation is obtained with a widely variable range of transmission ratio.The invention can be employed e.g. for the manufacture and operation of presses, clamping, bending and tension devices.

Abstract: Metal strips or foils more than 800 mm wide are brought to an end temperature of 100.degree.-300.degree. C. by stepwise heating. The strips or foils are deflected at an angle (.alpha.) of 15.degree.-150.degree. C. over 2 to 6 rolls set at increasing temperatures in the direction of throughput, at least the last roll having a double outer layer that can be heated, and the last roll being set at the final, desired temperature. The increases in temperature from one roll to the next lie between 20.degree. and 70.degree. C., preferably between 50.degree. and 60.degree. C. Usefully all the increases are the same. The process according to the invention is employed in the manufacture of composites and in the laminating and lacquering or painting of metal strips or foils.
