Patent DE-2835052-A1 (DE)
Inventor: SIEGWART EMIL
IPC: F24F11/75
Filed: 1978-08-10
Abstract: An arrangement for regulating the flow of a gaseous medium in a conduit includes a flap valve pivotably mounted in the conduit and biased by a spring toward its open position and by the pressure of the gaseous medium flowing through the conduit towards its closing position. A rod-shaped member is pivotally mounted on one section of the flap valve, and a sleeve-shaped member is pivotally mounted on a plate-shaped element rigid with the conduit and extending axially thereof downstream of the flap valve. The sleeve-shaped member has a passage therein in which the rod-shaped member is received with play so that, upon rapid movement of the rod-shaped member in the passage, the sleeve-shaped member is entrained by friction on pivots, thus seizing the rod-shaped member. In this manner, the flap valve is prevented from fluttering, while its responsiveness to gradual pressure changes of the gaseous medium is unaffected.

Title: Marking out of garment section patterns on fabric - by means of aerosol dispersing wetted powder around profile
Inventor: BADDE ANGELIKA
IPC: A41H3/01
Filed: 1978-08-26
Abstract: With the help of an aerosol or other propellant device, a material which can be atomised into fine granules such as powdered chalk, is sprayed onto a fabric along the edges of a dressmaking pattern, so as to mark out the contour. The granular material may be mixed in with an easily vapourised fluid. The nozzle directs an acutely conical jet with an outlet angle of 5 to 25 degrees towards the edge of the pattern. The process not only prevents the tearing of the tissue paper pattern, but also ensures that the contour is marked out accurately and quickly on the thinnest and most elastic fabrics.

Title: Paper pulp shredding mill - fed with water and air under pressure and at high temp., through porous coating
Inventor: SCHMOELLER KARL-HEINZ
IPC: B27L11/06
Filed: 1979-02-20
Abstract: Paper pulp is produced from wood in a shredding mill comprising a concrete central body with a porous shredder coating disposed on its peripheral surface. In the process, water is brought to the shredding zone, at least in part, from the inside of the shredding mill, passing through holes in the central body to strike against the porous shredder coating, and through this outwards into the shredding zone. Water and air may be fed in under pressure, and the water is heated before delivery. The water feed may easily cross the porous coating material, to ensure a copious quantity of water reaching the outer surface of the shredding mill, thus feeding the shredding zone, and avoiding the possibility of premature evaporation. The water may further be fed at higher temps which assists the softening of the lignin. By feeding pressurised water and/or compressed air, the temp. of the water may be increased before it reaches boiling point, which improves the milling process. Further, after stoppage, the mill may be re-started, fully charged without delay to warm up. Steam may also be fed directly through the shredder coating to moisten it like a sponge.
