Abstract: La soupape à bille décrite, qui est du type à tourillon, comprend un logement de soupape (1) présentant des ouvertures d'entrée et de sortie (4, 5) de préférence concentriques et dirigées dans des sens opposés (4, 5), pourvues chacune d'un siège interne (12, 12'), ainsi qu'un corps de soupape en forme de bille réversible, constituant la bille de soupape (2), qui comporte un passage traversant central (3) destiné à être sensiblement aligné sur l'entrée et la sortie (4, 5), la soupape étant en position ouverte, et qui sert à fermer le passage traversant le logement de la soupape, celle-ci étant en position fermée, tout en maintenant un état d'étanchéité au niveau des sièges (12, 12') du logement de soupape. Pour produire une soupape à bille de ce type, dans laquelle la bille est amenée mécaniquement, sans force élastique ni pression différentielle, à effectuer un mouvement de rotation dans la position fermée, maintenant ainsi une étanchéité optimale au niveau des deux sièges (12, 12') du logement de soupape, la bille de soupape (2) est pourvue de deux joints étanches diamétralement opposés (15, 15') qui, la soupape étant en position fermée, sont destinés à coopérer simultanément et hermétiquement chacun avec l'un des sièges (12, 12') du logement de soupape (1), les surfaces d'étanchéité (17, 17', 16, 16') des sièges de soupape et des joints étanches de la bille s'étendant excentriquement par rapport au point de rotation de la bille constitué par son centre géométrique. Comme les surfaces d'étanchéité des sièges et des joints étanches sont excentriques, l'effet d'étanchéité est optimisé avec une force de serrage mécanique croissante et, la soupape étant en position ouverte, au niveau de chacun des sièges (12, 12') du logement de soupape, est prévue une fente ayant une superficie d'écoulement plutôt importante vers l'intérieur du logment de soupape, ce qui permet un rinçage efficace des composants internes de la soupape au moyen d'un petit écoulement partiel du fluide passant à travers elle.

Patent CA-2085805-A1 (CA)
Title: Fluid flow rate measuring apparatus
Inventor: FRIEDRICH JAROMIR
IPC: G01F1/20
Filed: 1992-12-18
Abstract: ABSTRACT OF THE DISCLOSURE   A liquid flow measuring device has a deflector (31, 69) slidably mounted relative to a cylindric inlet of the liquid to be measured, for a minute displacement along the axis of the inlet conduit. The deflector is exposed to the static pressure created by the fluid. It has a concavely shaped deflection face shaped to reverse the flow of the incoming liquid. The flowing liquid creates a dynamic force vector at the deflector in the direction of the axis thereof. The dynamic force at which the deflector is urged by, and in the direction of, the incoming flow is sensed by an electric pressure cell (42, 81) whose electrical output is then directed to a suitable indicator (47) or controlapparatus. The device presents a simple arrangement. Yet, it is sensible to even minor variations in the rate of flow of the liquid due to the fact that virtually the entire flow participates in the generating of the pressure active at deflector and thus at the cell (42, 81).

Title: Membrane-based process for the recovery of lactic acid and glycerol from a corn thin stillage" stream
Inventor: BENTO JOHN MARIO A
IPC: B01D61/58
Filed: 1993-07-05
Abstract: MEMBRANE-BASED PROCESS FOR THE RECOVERY OF LACTIC ACID AND GLYCEROL FROM A "CORN THIN STILLAGE STREAM                 ABSTRACT OF THE DISCLOSURE    "Thin stillage", discharged from a centrifuge in which relatively large >10~m insoluble solids in an ethanol stillbottoms stream are separated from "whole stillage", is separated in a step-wise membrane separation process to recover lactic acid and glycerol, together. In each step, the permeate recovery is at least 50%. In a first step, an ultrafiltration (~F) membrane means produces a UF permeate stream in which not only essentially all the insoluble por-tion of said thin stillage >0Ø05~m is removed as UF con-centrate, but also at least 50% of solubles having a molecular weight >2x105 Daltons, including dissolved proteins in said thin stillage. In a second step to which the UF permeate is fed, a nanofiltration (NF) membrane produces a NF permeate with a rejection of less than 30% of both the lactic acid and the glycerol, preferably less than 25%. Essentially all molecules larger than lactic acid or glycerol are removed in the NF concentrate. In a third step, to which the NF permeate is fed, a reverse osmosis (RO)membrane means produces demineralized RO water which contains essentially no lactic acid and glycerol, because these are rejected in the RO concentrate. Use of the membrane separation process in the production of ethanol based on the dry-milling of corn, eliminates the use of a conventional evaporator.
