  • Patent number: 6861491
    Abstract: A method for producing thermosetting polyurethane after transformation from thermoplastic polyurethane with a hydrolyzable organo-silane which is grafted onto macromolecules of said thermoplastic polyurethane by means of a bonding agent. Said organo-silane has general formula (I), wherein R1,R2,R3=aliphatic alkyl, aromatic alkyl; n>1; R4 is an organic radical which can react with said bonding agent which comprises at least two isocyanate functions and the thermoplastic polyurethane obtained can, after transformation, become automatically cross-linked by coming into contact with water molecules in order to become thermosetting. The invention also relates to a product which can be obtained according to the inventive method.

  • Patent number: 5435641
    Abstract: A cabinet formed from a unitary open-faced cubicle structure having two lateral walls, an upper wall, a bottom wall, and a rear wall. A door closes the open face of the structure. The cabinet has at least one chimney along one lateral wall, the chimney extending from the front, open face to the rear wall of the cabinet. The chimney opens at both the rear wall of the structure and the front face of the structure. The opening at the front face is positioned to receive a lock carried by the door. Therefore, the lock is isolated from the interior of the cabinet, and the interior is protected from entry of dust and moisture. The cabinet also has a flashing system in the vicinity of its edges, which prevents entry of water into the interior of the cabinet. Additionally, the cabinet has edges in the vicinity of the door that provide additional pressure on seals within the door.
