Abstract: 1,177,438. Controlling microbiological processes. KYOWA HAKKO KOGYO CO. Ltd. June 24, 1968 [June 30, 1967], No.29945/68. Heading C6F. The cultivation of micro-organisms e.g. yeast, in culture flasks or tubes mounted on a shaking machine 7 within a culture chamber 1 is controlled by producing a pressure difference between the inside and the outside of the culture chamber in a regular sequence and utilizing this pressure difference as an impulse to increase the supply and exhaust of gas across the gas permeable stoppers of the flasks or tubes within the chamber. Pressure differences of plus to minus one meter of water head at a rate of between 5 and 10 pulses per minute are suitable. These are produced by operating the valves 4 and 5 such that in the one arrangement gas e.g. air, is taken from a tank 9 through blower 3 and into the culture chamber 1, and in the other arrangement the gas is taken from the culture chamber 1 through the blower 3 and back into the tank 9. The fermentation of a butaneassimilating micro-organism may be controlled by increasing or decreasing the partial pressure of butane in the pressure air. Similarly, the pH of a fermentation medium may be regulated by alternately adding hydrogen chloride gas and ammonia gas to the pressure air.

Title: Improvements in and relating to the concentration by evaporation of heat sensitive liquors
Inventor: REAVELL JAMES ARTHUR
IPC: B01D1/28
Filed: 1949-11-24
Abstract: <PICT:0687106/III/1> Heat-sensitive liquids such as fruit juices, coffee extracts and milk, are concentrated by evaporation under reduced pressure in a climbing-film evaporator, by heat-exchange with a compressed gas such as ammonia or sulphur dioxide.  The compressed gas is thereby liquified in the evaporator and the resulting liquid, after cooling, is used as cooling-medium in the condenser for the process-vapours.  The cooling liquid vaporizes in the condenser; and the gas, after compression, is re-circulated to the evaporator.  The liquid heating-cooling medium is preferably cooled, between the evaporator and the condenser, by heat-exchange with cooling water and partial flash-vaporization. Weak liquor is passed from storage-tank 1 through heater 3 wherein the temperature of the liquor is raised several degrees above its boilingpoint under the low-pressure existing in condensers 5 and 9.  The heated liquor flows through valve 2 into separator 4, which is maintained under reduced pressure, so that flash-vaporization of part of the liquor occurs.  The separated vapour is condensed in condenser 5, the condensate being withdrawn by pump 6.  The liquor withdrawn from separator 4, is passed to climbing-film calandria-evaporator 7 wherein further evaporation takes place.  The mixture of concentated liquor and vapour enters separator 8; the separated vapour passes to condenser 9 from which the condensate is removed by pump 10, and the concentrated liquor is withdrawn from the separator by pumps 11.  The heating and cooling in the system is effected as follows:-Compressed gas from compressor 12 is introduced through valves 13 and 14 into the calandria of evaporator 7 and heater 3. The greater part of the compressed gas is condensed to liquid by heat-exchange with the process-liquor; and the two condensates are passed, by way of traps 15 and 16, through coil 17 which is mounted in a tank supplied with a continuous flow of coolingwater, introduced through valve 18 and withdrawn at overflow 19.  The cooled liquid is then passed through expansion valve 20 whereby a part of it is flashed into vapour.  This vapour is separated in receiver 21, and passed through pipe 25 to compressor 12.  The cooled liquid from receiver 21 is introduced through pipes 22, 23, 24 into condensers 5 and 9 wherein it absorbs heat and evaporates, by heat-exchange with the process-vapours from separators 4 and 8 respectively.  The vaporized gas is passed to the compressor through receiver 21 and pipe 25, for compression and recirculation to evaporator 7 and heater 3.  Specifications 498,305 and 575,118, [Group VI], are referred to.

Abstract: 1392465 Secret transmission STANDARD TELEPHONES & CABLES Ltd 29 June 1972 30582/72 Heading H4R In a secret transmission system an intelligence signal is transmitted over two paths in antiphase together with different linear combinations of a number of different noise sources while a further different linear combination of the noise signals is applied over a further path. The wanted signal is recovered by mixing signals from the paths in predetermined proportions. In a preferred embodiment, Fig. 4, signals U 1  and U 2  are transmitted in respective directions between stations 1 and 2 with independent noise generators n 1  and n 2  at the respective stations. The wanted signals U 1  and U 2  and noise signals n 1  and n 2  are mixed in the mixing networks so that each station transmits to two channels through respective mixing networks N 15  and N 35  or N 25  and N 45  and derives an output signal from a respective mixing network N2R and N1R with wanted signals, mixed with different noise signals on all the connecting channels 10, 11, 12, and 13 and all the mixing circuits having four inputs and one output. In an alternative arrangement, Figs. 9 and 10 (not shown), balanced wanted signals are transmitted over a four wire line between two stations with each wire of the two pairs being treated as an independent signal channel, the sheaths (95, 96) of the two pairs used as further independent channels for the transmission of noise signals and the overall cable sheath as a reference earth. In this arrangement the four independent noise generators (n 1 <SP>1</SP>, n 2 <SP>1</SP>, n 3 <SP>1</SP>, n 4 <SP>1</SP>) used are all located at one station, e.g. the exchange, and the noise signals are added to the lines via impedance matching networks (NI 1 , NI 2 , &c.). In this arrangement attempts to tap the lines to listen to the signals thereon cause unbalance and increase in noise level at the receiver, indicating unauthorized interference.
