Title: Process for destructuring lignocellulosic matter
Inventor: GRANGER MICHEL
IPC: A23K50/15
Filed: 1984-03-06
Abstract: Process for destructuring lignocellulosic matter originating from agricultural waste and scrap timber using an oxidising alkaline treatment. According to the process the cellulose substrate is subjected to a treatment with an alkaline aqueous solution of a peroxide compound: hydrogen peroxide and its solid derivatives capable of reconstituting the H2O2 molecule in an aqueous medium, by itself or mixed - activated by a compound chosen from the class of cyanamides and derivatives, the cyanamide active principle CN2 being used in a proportion by weight of between 0.2 and 3 % relative to the solids content of the substrate. Application of the lignocellulosic matter destructured according to the process in feeding ruminants, in biochemical processes for conversion into sugar, alcohol and protein and for a subsequent bacterial delignification of papermaking pulp.

Title: Process and plant for the manufacture of granulates intended for the manufacture of magnetic tapes or of similar image and/or sound support media, in particular made from polyester
Inventor: GEIER RUDOLF
IPC: B29C48/40
Filed: 1984-11-22
Abstract: This relates to a process and a plant for increasing the roughness and antiblocking propensity of magnetic tapes made from polyester, according to which an additive, which promotes roughness and prevents blocking, is added to the tape originating from a polymer, during its manufacture. In order to do this, the additive is mixed with one part of the polymer, metered out and melted in an extruder, in a first treatment zone, and then dispersed in a second treatment zone with the other part of the polymer, after it has been metered out. The dispersed mixture is then sent into a third treatment zone subjected to a partial vacuum, ejected from the extruder and finally, in a known manner, granulated, dried and mixed with other polymers for special uses. In total, a particularly fine dispersion of the additive or additives is obtained in the polymer and in the magnetic tapes manufactured therefrom.
