Effect of the density of the electronic states at the valence orbital of the bridge redox molecule on the dependence of the tunnel current on the overvoltage in the case of fully adiabatic electron transition

Effect of the density of the electronic states at the valence orbital of the bridge redox molecule on the dependence of the tunnel current on the overvoltage and on the width at half maximum of the current-overvoltage curve is studied. A number of the approximate expressions for the density of states, the tunnel current and the width are obtained in the fully adiabatic limit for different particular cases. It is shown that at small values of the coupling of the electronic levels of the electrodes with the valence orbital of the redox molecule and the small values of the bias voltage two regions of the reorganization Gibbs energy exist with different dependence of the width on the reorganization Gibbs energy. The results of calculations of the density of states, the tunnel current and the width are presented and used for the interpretation of the experimental data [N.G. Tao, Phys. Rev.

Refractory compounds of basic composition for the monolithin lining of steel-teeming ladles

Conclusions Questions of the method of production of basic ramming compounds at Panteleimonovka Refractory Plant and their use in the monolithic lining of the walls of 160-ton steel-teeming ladles of the No. 2 Converter Shop of Kirvoi Rog Steel Combine are considered.An analysis of the wear of the lining during service showed that it occurs as the result of spalling of the sintered zone and salamandering of the lining. The use of a movable thermally insulated lid made it possible to hold the temperature of the ladle lining within limits of 730–1120°C between heats and to obtain a basic rammed lining life of 21–39 heats as opposed to an average life for the shop of 14.8 heats.A reserve for increasing the ladle basic lining life is optimization of the thermal conditions of its service, including high-temperature heating of the lining before pouring of the metal, the use of thermally insulated lids with the minimum consumption of time for placing of them, an increase in the life of the well refractory to the life of the walls and bottom, and elimination of cooling of the lining between heats.A Discussion: Problems of the Production and Use of Refractories for the Lining of Steel-Teeming Ladles.

Experimental technology for manufacturing ceramic articles

The production of ceramic articles includes five principal operations, namely, preparation of the powder, pressing of the preform, its treatment, sintering, and grinding. If it is necessary to increase the adaptability to manufacture and improve the physicomechanical properties of the sintered material, the operations of hydrostatic treatment of the powder, preliminary sintering of the preforms, repeated mechanical treatment, etc. can be added. The technology is used for manufacturing the working part of cutting tools, dies, tools for shaping alloys of nonferrous metals, bearings, hinges, valves, ball locks, nozzles of hydromonitors, parts of pressing molds, lining parts, milling bodies, etc.Translated from Ogneupory i Tekhnicheskaya Keramika, No. 6, pp. 25 – 27, June, 1996.     

Some gas phase reactions during the firing of magnesite-chromite refractories in a tunnel kiln

Conclusions A correlation is shown between the high-temperature, physicochemical processes in basic refractories, changes and reactions in the gaseous phase, and the nature of the wear of the roof of a tunnel kiln.As a result of dissociation, oxidation, and volatilization the waste gases are enriched with vapors of alkalis, CrO₃, sulfur trioxide, and oxides of iron and magnesium, and become corrosive with respect to the kiln lining. The reaction of the oxides vapors with each other and with the lining of the roof and their condensation determines the nature of the wear in the magnesite-chromite refractories, the chemical and mineral compositions of the resulting deposits and crusts. The main source of alkalis and sulfur trioxide is the sulfite yeast dregs (sulfite lye) present in the goods being fired.We determined the temperature relationship with the composition and amounts of deposits and crusts. Carcase and skeletal deposits and crusts formed on the firing section of the kiln, mainly periclase and spinel compositions; in the warming-up section the deposits were brittle, granulated, consisting of sulfates, chromates, chromium oxide, periclase, and spinels.It was found that the deposits on the walls of the pores in the MKhS refractories consist of sulfates and chromates, forming solid solutions.Translated from Ogneupory, No. 5, pp. 13–16, May, 1980.

Selektives Trocknen gemischhaltiger Produkte

Selective drying of mixture-containing products . Properties and quality of products containing solvent mixtures can be influenced considerably by the drying process. This concerns, e. g. the aroma content of fruit concentrates, the tear resistance of paper, the intensity of the colour of pigments, the ductility of cable insulation, toxic residues in tablets, residual monomers in polymers, etc. Both, the amount of residual moisture and its composition are of decisive importance. Predictions are possible given a knowledge of both the course of the drying curve and the course of the composition curve. The latter results from five basic physical processes, viz. vapour-liquid-solid phase equilibria, diffusion in the gas phase, diffusion in the liquid phase, capillary flow, and heat transfer. This combined action can be described both theoretically and experimentally for simple but indicative cases. There result practical hints for the choice of dryers and drying conditions to fulfill the demands placed on the properties of the dried product.     

Characterization of oils from low-gland and glandless cottonseed

New varieties of cotton which contain few or no gossypol pigment glands are being developed. Commercial production of such varieties should contribute to improving meal quality and reducing the color problems encountered with cottonseed oil. Samples of gland-containing, low-gland, and glandless seed grown in California were obtained, and the oils were extracted and characterized. With regard to the over-all characteristics the oils from the low-gland and glandless seed were indistinguishable from regular cottonseed oil. Iodine values, contents of unsaponifiables, cloud- and pour-points, response to the Halphen test, and similar characteristics resembled those of commercial cottonseed oil. No differences were found in behavior during winterization. Determination of the component fatty acids by gas chromatography showed the fatty acid composition of the oils to be typical. Determination of the positions of the double bonds in the unsaturated acyl groups showed no differences between the oils from gland-containing, low-gland, and glandless seed. Ultraviolet, visible, and infrared spectra of the oils revealed no differences other than the presence of gossypol in the crude oil from the gland-containing seed. The infrared spectra of the unsaponifiable fractions obtained from the oils showed some differences, which were not believed to be important.

Designing a band for a detachable unit of an induction channel furnace

Conclusions The calculations carried out indicate that a metal cylinder applied with a tolerance to the lining of the longitudinal channel creates stresses that are inverse in sign to the tensile forces at the danger site of the lining. This excludes the development of tensile forces in the danger zone of the lining, both during short-term heating and during prolonged service, i.e., it eliminates one of the main causes of cracking in the lining of the longitudinal channel of a detachable unit.During the development of microcracks in the lining, when the induction furnace is working, the band, tightening the lining, prevents microcracking. Moreover, the metal cylinder prevents penetration of melt into the heat-insulating layer through the pores of the lining, especially during vacuum melting.Translated from Ogneupory, No. 6, pp. 14–16, June, 1992.
