Abstract: A hot-extraction paper consisting substantially of cellulose and manufacturing assistants needed in cellulose and manufacturing assistants needs in cellulose production, such as pH modifiers based on acids and/or bases, the paper comprises exclusively cellulose having fibre lengths of at least 2.0 mm on length-weighted average, more particularly at least 2.5 mm on length-weighted average, and has isotropic extension properties which are substantially equal in machine and cross directions and amount to at least 7.5%, more particularly at least 8.5%.

Abstract: The invention relates to a facade construction comprising first thermal barrier elements which are arranged on a supporting framework, in particular of an outer wall of a building, second thermal barrier elements which are arranged on the first thermal barrier elements and a retaining device which is arranged on the supporting framework and holds the first and second thermal barrier elements on the supporting framework. The facade device further comprises an intermediate layer in the form of a multiplicity of mounting plates, which intermediate layer is attached to and supported by the retaining device, wherein the second thermal barrier elements are arranged on the intermediate layer.

Abstract: The invention relates to a transport device for welding wire feed for welding equipment, in particular arc sheild-gas welding tools on manipulators. The welding wire is transported from a magazine or reel with the aid of two separate drives. The main drive determines the feed and it is mounted near the application welding die, while the auxiliary is arranged spaced therebehind. The motor of the main drive is controlled to a constant speed corresponding to the selected feed, while the auxiliary drive acts on the welding wire with slip. The motor of the auxiliary drive is also controlled to a constant speed, the speed adjustment of the drives being, however, control-technologically connected for maintenance of a certain difference of the transport speeds.
