Abstract: A high-temperature insulation for thermally insulating pipes includes a carrier layer, wound helically to form a tubular main body and has four or more windings, and has three or more different insulating layers. The inner winding circumferentially surrounds the inner cavity of the tubular main body. The circumference of the inner cavity is at least 50 mm. The insulating layers are arranged in the gaps between the windings of the carrier layer and contact the carrier layer both radially inwardly and radially outwardly. The insulating layers are arranged in the carrier layer have, along the circular path specified by the winding, a length that corresponds to at least 80% of the circumference of the inner cavity of the tubular main body. The carrier layer, the first insulating layer, the second insulating layer, and the third insulating layer each consist of different materials and/or thermal conductivities and/or temperature resistances.

Abstract: The invention relates to a packaging unit of an insulating material, and, in particular, of high-temperature wool, preferably formed from a mineral fibrous raw material, and of a wrapper (6) made of a foil (6) or the like. To create a packaging unit (1), for which significantly less space is needed for transport and storage without destroying the inner fiber structure, thereby incurring enormous cost savings, particularly transport costs, an elongated insulating material (2) is rolled up into a bale (3) having straight long sections (4) and round short sections (5).

Abstract: In standardized mold making the structure of the mold is at present generally formed according to the following principle: A so-called clamping plate (1 to 3), having usually a larger width, is attached at the end of both half-molds and the other mold structure plates (4) are screwed thereto. The area of the clamping plate that projects the most on both sides is then used to connect the half-molds with the molding press. Thermal protection plates are often employed to minimize the heat transfer to the molding press. The thermal protection plates are commonly screwed onto the front surfaces of the clamping plates. This can lead to problems vis-a-vis the overall parallel alignment of the mold structures. The invention arises out of the underlying requirement to provide an optimal thermal protection over the entire equipment lifetime without limitations vis-a-vis the parallel alignment of the mold structures.
