Title: Process and installation for the production of ethanol by fermentation
Inventor: DAMBRINE FRANCIS
IPC: B01D3/00
Filed: 1985-11-20
Abstract: The invention relates to the production of ethanol by fermentation according to the process consisting in separating the wine obtained by fermentation into a yeast-enriched stream, which is recycled into the fermenter, and a stream practically free of yeast cells, at least part of which is sent into an evaporator where it is separated into an ethanol-rich vapour stream, which is fed to a distillation column, and a liquid stream, at least part of which is concentrated to give vinasses. In order to reduce the heat consumption of the installations designed for implementing this process, the evaporator consists of the final effect 71 of a multiple-effect evaporator in which the liquid and the vapour circulate countercurrentwise, and the liquid stream leaving this evaporator is concentrated in the preceding effects 72 and 73 of the said evaporator.

Title: Apparatus for stimulating circulation in the limbs
IPC: A61H15/00
Filed: 1987-11-26
Abstract: The invention relates to an apparatus for stimulating venous and lymphatic return circulation in the limbs. The apparatus is simple, and consists of a set of balls joined together by an elastic tie. Each ball is allowed a rotational movement, but no translational movement, this being by virtue of an intermediate piece which is integral with the tie. The modulus of elasticity of the tie is calculated as a function of the physiopathological requirements of the venolymphatic circulation deficiency in the limbs. The apparatus is manipulated using two rigid handles which are approximately 1 metre long. The apparatus is intended for relieving the symptoms of return circulation deficiency, by allowing manipulation by the patient himself, at reduced cost.
