Abstract: The door seal comprises a fixing element (20) for fixing to a door, a seal receiving element (40), a lowering mechanical unit (20) for lifting and lowering the seal receiving element (40) relative to the fixing element (20), and a sealing element (50) fixed to the seal receiving element (40). The sealing element (50) provides a first sealing line (54a) by means of a first sealing element portion (54) which can be lifted or lowered by means of the lowering mechanical unit, and the first sealing element portion (54) is a sealing lip and/or a sealing arc. The sealing element (50) provides a second sealing line (55a) by means of a second sealing element portion (55), said second sealing line running parallel to the first sealing line (54a). The second sealing element portion (55) has a first and a second side (52, 56), said first side (52) can be lifted and lowered by means of the lowering mechanical unit and said second side (56) is fixed in its position relative to the fixing element (20).

Abstract: A device for adjusting and fixedly securing window frames and door cases or the like within wall openings comprising at least one manually rotatable threaded shaft upon which a fixture is mounted and adapted to be connected with a portion of the frame, the fixture being supported upon a side wall of the wall opening, wherein the threaded shaft is directly supported upon the side wall of the opening by means of a thrust element at its free end, the fixture comprising a shaft nut portion, and wherein the fixture detachably grips the frame portion by means of support portions such that the frame can be fixedly secured with respect to the associated wall of the opening, and is also transversely displaceable.

Abstract: A supplementary device for driving screws by means of a power-driven screw driver having a driver blade or the like and the device comprising a holding member extending parallel to the driver blade, variable in its length and having a lateral extension, and a magazine disc releasably attached to and rotatably supported upon the lateral extension, the magazine disc being adapted to receive a plurality of screws arranged upon a circular locus, the axis of the driver blade substantially extending through a point of the circular locus and the screws being supported upon the disc such that they can be removed from the disc by means of axial pressure applied thereto by means of the driver blade.
