Patent FR-2728556-A1 (FR)
Inventor: DEVILLE JEAN
IPC: C01F7/0633
Filed: 1994-12-22
Abstract: Method of removing iron from supersaturated sodium aluminate solutions resulting from alkaline attack by the Bayer method of treating alumina-monohydrate-containing bauxite. The method comprises the successive steps of grinding and optionally desilicating, in the presence of a decomposed liquor fraction, and then attacking at a temperature above 200  DEG C, generally 240 - 270  DEG C, said ground bauxite possibly desilicated by the remaining decomposed liquor fraction, in order to solubilize the aluminate hydrate and form after the attack a suspension of insoluble residue or red mud in the sodium aluminate supersaturated liquor. After cooling and dilution, said supersaturated liquor is decanted to separate the mud or insoluble residue from the supersaturated liquor, which after filtering is decomposed in the presence of a seed. The invention is characterized in that, after attack and during cooling of the suspension by the gradual reduction of pressure in the reactors, a small quantity of a calcium-containing compound is introduced into the suspension at a temperature exceeding 140  DEG C.

Title: I.C. engine supercharging air temperature controller
Inventor: LAVERAN JEAN LOUIS
IPC: F02B29/04
Filed: 1995-05-18
Abstract: The temperature controller has a primary cooling heat exchanger (5) situated between a supercharging air compressor (8) and the engine's air intake (2). A switching system (16,17) directs the whole of the air from the compressor towards a first heat exchanger or to the engine air intake via a by-pass channel (15).
