Abstract: Case 4073 ELECTROCHEMICAL APPARATUS AND PROCESS         FOR MANUFACTURING HALATES                ABSTRACT OF THE DISCLOSURE        An apparatus for the manufacture of halate, such as sodium chlorate, includes an electrolytic cell having a plurality of anodes and cathodes, clearance passageways between the anodes and cathodes have electrolyte, hypohalite and gaseous electrolysis product, principally hydrogen, moving upwardly between them an enclosure covering the tops of at least four such passageways and narrowing down to a passageway extending upwardly from the top of the en-closure and a downward passage for circulation of electrolyte which includes an upper baffles portion and a lower unbaffled portion, the unbaffled  part being alongside the electrodes and extending to the bottom of the cell, from which electrolyte is drawn upwardly past the electrodes.  Natural circulation due to gravity flow and density differences between the liquid electro-lyte and that entrained in gas or having gas entrained in it is normally sufficient so that stirring or pumping means are not required.  The invention provides a means for converting higher current density cells to lower current density cells so as to be more energy efficient.  In such conversions additional anode-cathode units are installed between those already in place and gases generated from them are collected with gases generated from a adjacent originally present anode-cathode unit and are moved upwardly with entrained liquid through previously existing passages while other circulating electrolyte is moved downwardly, also through previously existing passageways, baffled and un-baffled.  Other aspect of the invention relate to particular types of spacers between electrodes and to more energy efficient lower current density electrochemical processes for manufacturing sodium chlorate.

Abstract: ABSTRACT        Growth of Acinetobacte? Sp. ATCC 31012 on various substrates and under varying conditions has been used to produce two classes of extracellular microbial protein-associated lipopolysaccharides (the "emulsans") which, on a weight-for-weight basis, are probably the most efficient emulsifiers discovered and which possess certain character-istics that permit these unique extracellular microbial lipopolysaccharides to be widely used in cleaning oil-contaminated vessels, oil spill management, and enhanced oil recovery by chemical flooding.  These classes have been named  ?-emulsane and ?-emulsane, both of which have substantially the same polymer backbone but differ from each other in certain important structural aspects.           Deproteinization of emulsane by hot phenol extraction produces the lipopolysaccharide components (the "apoer_1-sans") of each of such emulsane, which components have been shown to be completely N-acylated and partially 0-acylated heteropolysaccharides made up of a major amounts of D-galactosamine and an axinourons acid, the 0-lipoacyl portions of such apoemulsans containing varying percentages of fatty acid esters in which the fatty acids contain from about 10 to about 18 carbon atoms, base hydrolysis under mild conditions of the emulsans and apoemuslans produces derivatives (the "?-emulsans" and "apo-?-emulsans", respectively) which are completely ?-acylated and partially to completely 0-deacylated. Base hydrolysis under strong conditions of any of these products produces another derivate (the "proemulsans") which is completely 0-deacylated and is partially N-deacylated, Emulsans and apoemulsans, both of which biopolymers are strongly anionic, exhibit a high degree of specificity in the emulsification of hydrocarbon substrates which contain both aliphatic and cyclic components.  In addition, these extracellular microbial polysaccharides as well at their 0-deacylated and N-deacylated derivatives are absorbed or and capable of flocculating aluminosilicate ion-exchangers, such as kaolin and bentonite.

Abstract: ABSTRACT         There is disclosed a method of separating exhaled gas into two portions,  A body in a first duct is heated to a starting temperature.  The exhaled gas is passed through the first duct and around the body to cool the body.  When the temperature of the body has fallen by a predetermined amount, further exhaled gas is caused to pass through a second duct.  The apparatus for carrying out the method includes a heater, a temperature probe and a controller for controlling the actuation of the heater and of a valve for switching the flow to the second duct.  The invention is applicable to the separation of exhaled air into two portions, the first of which can be dis-counted and the second of which can have its alcohol concentration determined. In the second portion the concentration of alcohol should correspond to the concentration of alcohol in the blood.  The method according to the present invention utilises the new knowledge that the alcohol concentration in exhaled air varies continuously and is found both in the portion of respiratory air from the lungs and in the air from the other respiratory organs.  Even the respiratory air flowing when exhalation commences can be utilized to determine the testing moment, i.e. the time when the alcohol concentration is measured. The further exhaled air, hence the sample for the alcohol measuring sensor is introduced into a measuring chamber when the body is cooled by a temperature difference .DELTA. T.  Cooling of the body depends on the total volume of air which flows past the body, and on the period of time in which it flows by.  The re-quirement for the moment at which the sample is taken (i.e. the moment when the further exhaled air commences flowing through the second duct) is therefore met either by a large volume exhaled over a short period or by a small volume ex-haled over a fairly long period.  In both cases, reliable measured values for alcohol are obtained.  The individual differences between the individual test subjects do not affect the result of measurement in this connection.

Abstract: PHB. 32,649.                13 ABSTRACT:            A method of forming an emissive coating on a dynode substrate.  The method comprises the steps of vapour depositing afor example by evaporating or sputter-ing) a composite coating consisting of magnesium and aluminium onto the dynode substrate.  A 50 to 500 .ANG. thick layer of aluminium is vapour deposited over the composite coating and the aluminium layer is oxidized.  The coated dynode is then activated by heating it in an oxygen atmosphere at a pressure of at least 5 x 10-6 Torr oxygen at a temperature between 270 and 400°C.  The resulting secondary emissive coating contains from 1.5 to 90% by weight of magnesium.  The coated dynodes are used in channel electron multipliers which are suitable for use in electron display tubes such as image intensifiers or colour television display tubes.

Abstract: ABSTRACT              BURNING SOLID FUEL       Solid fuel such as coal is fed into an inlet shaft of the furnace through a rotary feeder constructed to prevent the admission of air.  Primary air channels supply the major part of the air required for combustion of the fuel in a region in which the fuel bed is sufficiently thick to avoid disturbance and the formation of "holes" by this air.  Further, narrower air channels supply sufficient, diffused and low velocity air to complete the combustion of the fuel without substantial entrainment of grit and ash.          Air is prevented from flowing in contact with the fuel up stream of the channels and the metering edge.

Abstract: WELL TREATING FLUID (C-845) ABSTRACT OF THE DISCLOSURE          The instant invention is directed to shear thick-ening fluids which comprise a water-swellable material (clay), present in a sufficient concentration so as to be capable of forming a stiff paste upon interaction with the water used, and water wherein the clay and water are kept separated by an intervening hydrocarbon-surfactant compo-sition.  The intervening oil phase prevents the interaction between the water and the clay phases and results in a stable, nonreacting, pumpable composite until such time as the oil envelope is ruptured by application of a sufficiently high shear force.  Upon such rupture, the materials inter-act rapidly forming a semi-rigid stiff paste.          Various well-control problems, such as oil and gas with blowouts, can be controlled by use of the above-described composite.  The composite is pumped down the well pipe. Exiting the orifices of the drill bit or a nozzle supplies the shear force needed to rupture the oil envelope thereby permitting the interaction between the clay and the water resulting in the formation of a stiff paste which can stop or prevent unwanted flow in or near the wellbore.
