摘要： A process is disclosed for transporting a thermally unstable viscous mass through a pipe with a predetermined breaking point for letting out an overpressure. When an overpressure is reached, said predetermined breaking point breaks and lets out the overpressure. The predetermined breaking point is located inside the pipe but is not part of the inner wall of the pipe.

摘要： The invention concerns a device for controlling the pressure in a flowing viscous material, the device being characterized by: an inlet (8a) through which the material flows into the device, a cylinder (9) capable of holding a particular volume of the material flowing in through the inlet (8a), a plunger (11) which has an aperture (11d) and is fitted to move in the cylinder (9), changing the capacity of the cylinder (9) as it moves, a receptacle (11a) which is fixed over the aperture (11d) in the plunger (11) and connected to the inlet so that the material flows from the inlet (8a) through the receptacle (11a) and through the aperture (11d) in the plunger (11) into the cylinder (9), an outlet (10a) connected to the cylinder (9) and through which the material is discharged from the device. According to the invention, the inlet (8a), the cylinder (9) and the receptacle (11a) must be tubular in design and the receptacle (11a) must slide in telescope fashion over the inlet (8a) when the plunger (11) moves.

摘要： In order to produce cellulose fibres, a solution of cellulose in a tertiary amino oxide is hot-shaped into filaments, the filaments are cooled and brought into a precipitation bath in order to precipitate the dissolved cellulose. Before being brought into the precipitation bath, the shaped solution is exposed for cooling to a substantially laminar gas current.

摘要： A device is disclosed for producing cellulose films by extrusion of a heated solution of cellulose in a tertiary amine oxide. The device has an extrusion die with an extrusion slit (15) and is characterised in that a coolant gas supply (2C) for cooling the extruded film is arranged directly underneath the extrusion die. This device is particularly suitable for producing cellulose tubular films.
