Abstract: PURPOSE: To facilitate the speed adjustment and miniaturize the device by controlling an electromagnetic valve which adjusts an oil stream from a hydraulic pump and a valve which by-passes the electromagnetic valve, in correspondence to the deviation between the rotating speed of an output shaft and the set temperature thereof.  
     CONSTITUTION: The constant speed control device comprises a control circuit 24 which compares the output of a pickup 22 which detects the rotational speed of the output shaft with the output of a speed setter 25, and delivers a signal corresponding to the deviation between both speeds to a pressure regulating electromagnetic valve 20. Further, there is provided a by-pass valve 21 which automatically by-passes the electromagnetic valve 20 when the deviation becomes large. The by-pass valve 21 leads a fluid pressure adjusted by the electromagnetic valve 20 to clutches 6 and 7 when the deviation is smaller than the predetermined value to control the clutch oil pressure in a semiclutched state. On the other hand, when the deviation is larger than the predetermined value, the hydraulic pump 2 is connected to the clutches 6 and 7 to put the clutches 6 and 7 in a directly connected state.

Title: Concentration of organic substance by reverse osmosis membrane
Inventor: NARUTO SATOSHI
IPC: C07C229/24
Filed: 1983-02-28
Abstract: PURPOSE:To remove inorg. salts and to concentrate an org. substance to a high concn. in high purity, by treating an org. substance solution containing inorg. salts with reverse osmosis low in a salt exhaustive ratio. CONSTITUTION:A solution mixture of an org. substance and inorg. salts is received in a recirculation tank 1 and subjected to reverse osmosis treatment by a reverse osmosis apparatus into which a reverse osmosis membrane low in a desalting ratio is inserted by using a pump 2. By this treatment, a part of inorg. salts and moisture in the solution mixture are permeated to the side of a permeation liquid A and a non-permeation liquid B containing the org. substance and the residual salts is recirculated to the recirculation tank 1. When treatment is successive, the concn. of the inorg. salts in the side of the non-permeation liquid B is also increased and, therefore, desalted water C in an amount corresponding to the flow amount of the permeation liquid A is flowed into the tank 1. By this method, the content of the inorg. salts is lowered by initial permeation pressure and the org. substance can be concentrated. In addition, because the reverse osmosis membrane is utilized, this method can be adapted to the recovery of the org. substance having a relatively low M.W. such as amino acid.
