Title: Diaphragm pumping system
IPC: G21C15/243
Filed: 1962-05-28
Abstract: 945,120. Reciprocating pumps. UNITED STATES ATOMIC ENERGY COMMISSION. May 28, 1962 [June 16, 1961], No. 20362/62. Heading FlA. In a diaphragm pump actuated by a reciprocating pump through a liquid column, the phase relationship between the diaphragm and the reciprocating pump is maintained by means acting in response to a fall in output from the diaphragm pump to temporarily increase the displacement of the reciprocating pump. In the embodiment shown, e.g., for pumping radio-active or corrosive liquids, the reciprocating pump is constituted by an hydraulically-actuated diaphragm pump 2 which acts through a liquid column in conduit 14 to reciprocate a pumping diaphragm 9. When a difference in phase develops between diaphragms 9 and 2, the fall in output from pump 9 is detected by sensing means 33, 34 which act to increase the stroke of a variable stroke pump 32 driving diaphragm 2. The pumping chamber volume of pump 2 is greater than that of pump 9 so that, when on its rightward stroke, increasing the stroke of pump 32 and hence pump 2 forces diaphragm 9 to its full right-hand position. Excess pressure in conduit 14 is relieved by valve 29. On the return stroke of the system, diaphragm 9 reaches its left-hand position before diaphragm 2, the remainder of the left-hand stroke of diaphragm 2 acting to draw hydraulic fluid into conduit 14 from a reservoir 25 via a check valve 27. The diaphragms are now in phase again and the normal output of pump 9 is detected by sensing means 33, 34 which act to reduce the stroke of pump 32 to its former value. A reservoir 24 and stop valve 22 may be used for initially filling conduit 14. In another embodiment diaphragm pump 2 is omitted and pump 32 acts directly on the liquid colum in conduit 14.

Abstract: 1423642 Yeast AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY MINISTRY OF INTERNATIONAL TRADE & INDUSTRY and MITSUBISHI GAS CHEMICAL CO Inc 9 May 1974 [11 May 1973] 20593/74 Heading C6F In a process for the culture of a methanolutilizing yeast involving the inoculation of a seed culture (or the cells) a strain of yeast capable of assimilating methanol into a nutrient medium containing methanol as the main carbon source and aerobically growing the yeast so inoculated in the medium, there is employed a seed culture which immediately before the inoculation, has been grown in a seed stage nutrient medium containing methanol as the main carbon source, with the methanol at a concentration greater than 0À1 wt per cent and not greater than 6 wt per cent. The Examples, directed to the cultivation of methanol utilizing Candida alcomigas, Saccharomyces me tha-nonfoams, Torulopoils methanofloat, Candida N-17 (NRRL Y-8024), Saccharomyces H-I (NRRL Y-8027) and Hansenvla alcoolica, respectively, serve to demonstrate that the growth induction period is significantly reduced when the methanol concentration in the seed culturing is kept within the stated range. The yeast began to propagate vigorously after an induction period of, say, 6 hours instead of 16 hours. The seed culture may be grown by batch fermentation or by continuous culture. The methanol concentration may be controlled by providing at least one of the nutrients, other than the methanol, in a growthlimiting concentration, or by other conventional procedures.
