Abstract: 1452449 Disrupting microbial cells IDEMITSU KOSAN CO Ltd 12 May 1975 [27 May 1974] 19937/75 Heading C6F Useful components are extracted from microbial cells by disrupting the cells in one or more stages except the final stage of a high-pressure multi-stage homogenizer and treating the disrupted cells with solvent in the remaining stages of the homogenizer to extract the useful components. Preferably the homogenizer is two-stage, the disrupting step being carried out only in the first stage at a pressure difference between the first stage (higher pressure) and the second stage of 100-1500 kg/cm<SP>2</SP>. The extracting step is carried in the second stage. The microbial cells may be fed as an aqueous suspension having a cell concentration of 1-25%w/v. Microorganisms which can be treated are yeasts, bacteria, actinomyces and algae. Examples describe the extraction of (1) protein from yeast. (Saccharomyces cerevisiae), (2) an enzyme (glutamate dehydrogenase) from bacterium (Brevibacterium sp) and (3) lipids from yeast (Candida utilis).

IPC: H01F7/08
Filed: 1959-06-11
Abstract: 897,230. Valves. GENERAL CONTROLS CO. June 11, 1959, No. 20005/59. Class 135. [Also in Group XXXV] To prevent hum in an A.C., plunger type, electromagnet, a liquid film is maintained between the plunger and its bore. The device is shown applied to a fuel valve, and comprises a coil 124 in a ferromagnetic casing 118 having a non-magnetic lining tube 130 in which a plunger 133 may slide. The casing consists of two tubular members 120, 121 which define a gap 123, and a shell 119 which is tapered to fit a corresponding recess in a body 117. The shell is located against a terminal block 129 by a spring 131. Plunger movements are transmitted by a push-rod 154 and a cylindrical lever 145 pivoted at 144 to operate a valve disc 151. Flexible bellows of synthetic rubber surround the lever 145 to provide a liquid seal. A stop 135, preferably of magnetic material, limits the plunger travel and is slotted to prevent it acting as a shading ring. The corresponding end of the plunger is recessed to prevent sticking. The liquid 158, e.g. oil, glycerin, silicone fluid or the like, has free access to both ends of the plunger, through the stop 135 and via channels 160 (Fig. 3, not shown), and a hole 159 in the otherwise closed end of the lining tube 130. The liquid also permeates between the plunger and liner and it is this film which prevents hum. The size of the hole 159 may be varied to ensure a given rate of plunger movement. In an alternative arrangement (Fig. 1, not shown), the liner is completely closed at one end and the liquid gains access to that end via a groove in the plunger. The push-rod, lever and liquid seal are also of different construction, the latter being a flexible disc, and no plunger stop is provided.

Abstract: 977,917. Electric data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 30, 1962 [June 6, 1961], No. 20753/62. Heading G4C. Audio signals each forming a word are stored one word to a track of a magnetic drum 10. The addresses of words required on a number of output channels are stored on a magnetic core store, word memory 23. During one revolution of the drum the addresses in word memory are scanned repeatedly and to required audio signals time multiplexed on to output channels. The drum has an additional track carrying a single sync pulse. On the detection of the sync pulse a computor command is generated which provides a succession of addresses for the word memory, flip-flops FF2 and 3 are reset and FF1 is set, and the stage RD-1 of the scanner is set. FF1 opens gate 25 to clock pulses which step the scanner through its hundred stages, one read and one write stage for each of the fifty locations in word memory which correspond to the fifty output channels. Each clock pulse complements FF2. Gate 37 is thus open and a write pulse energizes the write drivers 29 to 35 at the same time as the write stage of the scanner are set In this way a set of fifty addresses are delivered from the computor to drum register 27 and from the drum register through the write drivers to the word memory. The drum register 27 is cleared by the signal from gate 37 just after the write pulse has arrived. When stage WRT-50 of the scanner is set, FF3 is reset thus opening gate 26 to every second clock pulse to provide an audio sample signal, and also removing an inhibiting bias on sense amplifiers 41 to 47. The scanner has recycles. At stage RD-1, the first row of the word memory is read out to drum register. At stage WRT-1, the contents of the register are decoded to open one of the gates Wg. Audio sample is the signal enabling the decoding to take place. The set stage also opens gate 12 to pass the sample of the drum track to the first output channel. A write pulse rewrites the contents of the drum register into the first row of word memory. The process is repeated for the stages RD-2 and WRT-2, the second row being operated on and the corresponding word from the drum being gated to the second output channel, and for the following stages. The drum track selection sequence continues using the same addresses until the sync pulse is again detected after one revolution of the drum.
