Patent AU-628680-B2 (AU)
Title: Micro-filtration method
Inventor: MUELLER WOLFGANG
IPC: C12H1/06
Filed: 1990-10-31
Granted: 1992-09-17
Abstract: The invention relates to a microfiltration process, in particular for separating beer from a materials flow which is purged during the fermentation process and which takes along the excess yeast produced during the fermentation, wherein the materials flow containing haze substances to be filtered is passed under pressure through at least one microfiltration module with porous membranes carrying a tangential flow and a filtrate is taken off. According to the invention, the materials flow to be filtered is continuously fed to a circulated retentate flow, and a concentrate flow having a substantially constant concentration of haze substances is taken off from the retentate flow. The flow velocity and the flow pressure drop of the retentate flow are measured and the concentration of haze substances in the retentate flow is determined from the measured data according to a function F (v,  DELTA p) which is characteristic of the apparatus and which contains the flow velocity (v) and the flow pressure drop ( DELTA p) as variables. The concentrate flow rate is controlled in accordance with the difference in the concentration of haze substances, resulting from a comparison of actual and set values.

Abstract: PURPOSE:To maintain the engaging force of lock-up suitably for vehicle speed condition, by comparing between the governor pressure and a fixed level pressure, and as well by using the higher one of both pressures as the control index of the engaging force of a direct coupling clutch. CONSTITUTION:When the vehicle speed raises so that a speed change ratio in the intermediate stage is established, a timing valve Tv moves leftward to take a second switching position, and therefore, an oil passage 95 is communicated with an oil passage 83. As a result, hydraulic pressure let from a high select valve Vs to a second pilot chamber 99 in a modulator valve Mv, is set to either one of the governor pressure Pg and the lubrication oil pressure Pu, which is larger than the other, and the hydraulic pressure which is an increased value of the larger one of the pressures is used as the output hydraulic pressure of the modulator valve Mv or the working hydraulic pressure of a direct coupling clutch Cd. By suitable selecting the degree of the lubrication hydraulic pressure Pu, the lock-up of the direct coupling clutch may be maintained even upon running at a speed lower than the lock-up vehicle speed.
