Abstract: A process for the manufacturing of a valve (1) having a rigid carrying body member (2) and a gasket member (3). The gasket member (3) is moulded through means of injection moulding in an elastic thermoplastic material by means of a gasket mould. Said gasket member (3) is then arranged in a body member mould, said body member mould being intended for moulding the carrying body member (2). A thermoplastic material is injected into said body member mould thereby mechanically integrating said gasket member (3) with said carrying body member (2).

Abstract: Transport assembly comprising a transportation means which comprises a pallet-like carrying structure with two long sides, two short sides, four corners, an upper surface and a lower surface. The carrying structure is provided with wheels at each of the four corners of which at least two of the wheels possibly are of the swivel castor wheel type. The upper surface is furthermore provided with receiving means which are intended to receive the wheels of a second transportation means stacked on top of a first transportation means so that a number of such transportation means may be stacked, and fixated horizontally, one on top of the other. The upper surface is provided with two narrow long side channels arranged parallel to the long sides and stretching from one short side to the other.

Abstract: Flat or semi-flat element (1) including a partly or completely circumambient frame (2), which element (1) is manufactured through molding of a polymeric material. The element (1) includes a carrying structure, constituted by the frame (2), and an intermediate wall section (3). The wall section (3) is connected to the frame (2) via a resilient section (4), the resilient section (4) being a part of the wall section (3). The differences in the temperature related shrinkage between the frame (2) and the wall section (3) is absorbed by the resilient section (4), whereby warping of the element (1) is avoided.
