A device for preventing axial movement of an elongated member (1) applied through the skin of a mammal at a puncturing position has a plaster (2) designed to cover the surface around the puncturing position and having at least an adhesive layer (4) for securing it to the skin as well as an opening (9) through the layer thereof for the passage of said elongated member therethrough. The device also has a clamp (8) secured to plaster and adapted to clamp around the elongated member when the elongated member is applied to the skin and the plaster is applied on the surface around said puncturing position. The clamp is thin and substantially flat.

The invention relates to a diffuser having a substantially cylindrical container through which cellulose pulp is arranged to be transported, nozzle arms for delivering a fluid to the pulp, a scraper arm with scrapers spaced apart from the nozzle arms, and concentrically disposed screen surfaces and screen arms disposed on and connected to the screen surfaces for withdrawal of the fluid. The screen arms are provided, at their outer ends, with fixed, non-pivotal withdrawal pipes that are slidably controlled and are connected in sealing arrangement to filtrate outlets. The screen arms have interior withdrawal areas with increasing cross-sectional areas as the screen arms extend toward the withdrawal pipes. The screen arms also include long and short plugs for controlling the filtrate flow capacity of the diffuser. The invention relates also to a stuffing box designed to receive a rod, preferably a pull rod for raising and lowering a screen pack having screen surfaces in a diffuser, the rod being guided in sealing arrangement and slidably through a fixture which is mounted in a bearing for free movement in a plane substantially perpendicular to the rod. The bearing comprises a radially directed bearing flange extending around the fixture, which bearing flange is mounted between two radially directed retaining flanges extending around the fixture.
