Filed: 1997-01-22
Abstract: The invention concerns a method for processing alumina monohydrate by means of a sodium attack at high temperature characterised in that it consists of the following successive steps: a) disintegrating at more than 200  DEG C the bauxite with a concentrated solution of more than 160 g Na20/litre of which the weight ratio ranges between 0.45 and 0.75, during a contact time sufficient for solubilising the alumina monohydrate and for reaching a weight ratio ranging between 1.10 and 1.20; b) cooling the suspension and introducing alumina trihydrate in said suspension, to less than 200  DEG C, so as to obtain a weight ratio of the aluminate solution ranging between 1.20 and 1.30; c) a first dilution for obtaining a concentration ranging between 160 and 175 g Na20/litre; d) decanting so as to separate from the insoluble residual matter a sodium aluminate solution of which the weight ratio ranges between 1.20 and 1.30; e) filtering the aluminate solution; f) complementary dilution before or during decomposition; g) recycling, after separating the alumina trihydrate by filtration, the decomposed solution which, after concentration, is used again as attack solution at the start of the process with a concentration higher than 160 g Na20/litre.

Title: Control mechanism for stopping or recovering winding-unwinding devices of flexible products
Inventor: MAZEAUD GUILLAUME
IPC: B65H75/44
Filed: 1997-10-30
Abstract: The invention concerns a control mechanism for a winding device comprising a rotating cylinder (800) on which is wound a flexible product capable of being wound for being subjected to a traction in the unwinding direction ( alpha ), said cylinder (800) being further provided with return means (100) operating in the winding direction ( omega ), characterised in that it comprises a stop mechanism (400) capable of taking two distinct states (blocking state and releasing state), said stop mechanism co-operating with a release system (300, 460), said release system being itself capable of taking two distinct states (blocked state, restarting state). Said stop mechanism (400) and said release system (300, 460) co-operate such that, when tensile load ( alpha ) is interrupted on the flexible product capable of being wound, the stop mechanism (400) travels along a different cycle for changing the state on the basis of its initial state and of the angular displacement travelled by the cylinder (800) when said traction is exerted on the flexible product capable of being wound.
