Title: Heat recovery from gaseous exhaust of pulping mill - using condenser preceded by gas scrubber employing recycled condensate
IPC: B03D1/14
Filed: 1982-03-09
Abstract: In the thermo-mechanical pulping of wood chips in an atmosphere of steam, heat is recovered from the resulting mixt. of vapour, gas and solid particles by condensing at least one of the component vapours, and the condensate is used in a scrubber which precedes the condenser to remove solid particles from the mixture entering the condenser. The solids-condensate mit. is returned to the pulping mill from which the gaseous mixture is extracted. The condensate is sprayed into the scrubber through an atomiser, and collects in the bottom of the scrubber, where the solids are concentrated by flotation before being recycled. This arrangement keeps the condenser clean and corrosion-free, and prevents environmental pollution by removing the solids from the exhaust gases. The heat is the exhaust is almost completely recovered, with almost no loss of pressure in the recycled steam.

Title: Machine for delivering materials in film form.
IPC: B65H16/02
Filed: 1982-07-13
Abstract: The invention is an apparatus essentially intended for delivering materials of the film type which are received as rolls. Its main element is a rewinding rotor consisting of a shaft 8 and of rails 2 carried by arms 10. A fixed rail 3 is fitted with a device 12 pinching hold of the initial edge of the film. The other rails can be moved closer to the shaft, at least at one end, in order to facilitate the release of the delivered film. However, for certain films, a rotor of constant cross-section may be suitable. The shaft of the rotor rotates in bearings of the support 4. For the stripping process, it is released from one bearing and it remains embedded in the other bearing designed for this. A manoeuvre of the pinching device 12 releases the film, which is extracted longitudinally from the rotor whose diameter is optionally reduced, simultaneously with the unpinching operation. The invention relates particularly to cutters for materials in film form: plastics, metal or plastic netting, coverings for grounds or walls, fabrics, papers, etc.
