Abstract: A floor joist system (9) comprises a flat sheet metal structural web member (10) for interconnecting a pair of parallel spaced apart wood chord members (11), said web member (10) being V-shaped, comprising first and second legs (12, 13) integrally joined at one of their respective ends, a plurality of teeth struck from said one end of each leg (12, 13) and extending from one face, constituting the inside face, of the web member (10), said teeth being adapted to be driven into one of the chord members (11), and a plurality of teeth struck from the other end of each leg and extending from the inside face of the web member (10), said teeth being adapted to be driven into the other of said chord members (11). The system further comprises a bracket (1) for holding a suspended ceiling.

Abstract: A bracket (1) for holding a suspended ceiling has a first end (2) for anchoring the bracket (1) to a beam or the like of a building structure and a second end (3) to which a mounting profile is attachable on which a building panel is mountable. The bracket (1) has a rectangular and flat part (4) that in use is horizontally arranged between the first and second ends (2, 3). The length (L) of the flat part (4) between the first and second ends (2, 3) is at least 1.5 times as long as the width (W) of the flat part (4).

Abstract: A sealing assembly (1) for a rotary shaft (2), having a metal structure (4) defined by a sleeve portion (6) and by a radially inner flange (7), and a sealing ring (5) cooperating in sliding manner with the shaft (2); the sealing ring (5) in turn has a connecting portion (15) for connection to the flange (7), and a portion (18) projecting from the flange; two sealing lips (19, 20) extend axially from opposite sides of the projecting portion (18); the two sealing lips (19, 20) and the projecting portion (18) are connected in one piece to one another at respective narrow sections (21, 22, 23), each defining a respective virtual hinge permitting rotation of each element with respect to the others; and the respective centers of rotation (A, B, C) of the virtual hinges are defined, at each axial section of the sealing assembly, by three points arranged substantially in the form of a triangle.
