Patent PL-203004-B1 (PL)
Title: Fireproof profile component and method for production thereof
Inventor: GUETTER HARRY
IPC: E06B3/267
Filed: 2002-09-09
Abstract: The invention relates to a fireproof profile component (1), for the production of windows, doors, wall elements, facades and similar. Said component comprises two essentially U-shaped profile pieces, in particular made from extruded aluminium with an inner support shell (3) and an outer support shell (4) and which are connected to a composite profile (35), surrounding a single hollow chamber (H) at the free branch ends (300, 301, or 400, 401) thereof on the branch (5) of the U-shaped profile by means of thermally-separating insulating webs (6). The hollow chamber (H) is at least partly filled with a fireproof insulating mass (7). The particular advantage of said single-chamber composite profile with regard to fireproofing, is based on the fact that a large amount of fireproof insulating mass can be charged in the composite profile with the hollow chamber (H), thus forming a stable insulating block, in which the corner angles and connecting means can also be embedded. In conventional multi-chamber composite profiles this is not possible within the confines of the invention. Various production variants of the profile component (1) are disclosed, comprising amongst others, the user of a mortar-like hardening fireproof insulating mass (7), the use of pre-prepared insulating mass pieces and the recessing of unfilled partial chambers (37) in the hollow chamber (H).

Title: A packaging material of the corrugated cardboard type
Inventor: RYDBERG TOMMY
IPC: E04C2/34
Filed: 2003-03-06
Abstract: A packaging material of the corrugated cardboard type includes a laminate of at least one plane paper layer ( 1 ) and at least one auxiliary paper layer ( 3 ) with waves presenting an amplitude perpendicular to the plane of propagation of the auxiliary paper layer. The two layers are joined by means of a gluing material. The auxiliary paper layer ( 3 ) includes furthermore a system of substantially parallel waves ( 10, 10', 10 ''), the amplitude of which is in the plane of propagation of the auxiliary paper layer ( 3 ). As a result, the packaging material is more stiff than hitherto known without the lightness and voluminocity of the material being affected. In addition, the material possesses an increased tear resistance and is very suited for being provided with prints.
