ISSN: 1573-8906Source: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyNotes: Conclusions 1. The design formulas recommended in educational and technical literature for determining temperature deformations cannot be used for practical purposes. This is due mostly to the fact that it is virtually impossible to determine the temperature which affects deformations. It is not always clear which component or which dimension is subject to temperature deformation, not to mention the fact that the linear expansion coefficients are hardly ever known. In all the measurements temperature oscillations were observed within the range of a few degrees even in a single instrument. 2. In view of the impossibility of using computation formulas recommended in literature, temperature corrections cannot be applied in production measurements. In those cases when such corrections, nevertheless, have to be used, they should be determined experimentally for the various production conditions. Work should be directed in this field towards producing conditions for which no temperature correction are required. 3. It is necessary to provide the majority to hand-operated instruments with thermal-insulating spacers so as to reduce the effect of the operator's hands heating up the instrument and altering its dimensions. Instrument-making plants should check up all their instruments for the effect of temperature deformations. 4. In order to reduce the effect of the heat produced by the hands on the error of the instrument it is necessary to grip it and hold it in the operating position for 5 to 15 min before setting it to the required dimension.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-8906Source: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyNotes: Conclusions The application of computers in the measurement of linear and angular dimensions follows a certain specific direction. Widespread application of computers requires cooperation of several specialized organizations. Even now it is necessary to set up departmental and interdepartmental stations, for example within the staff of the Gosstandart, which would assist organizations and enterprises in the application of computers for getting the fullest possible data on the measured parameters. It is necessary also to set up computing centers which would serve the industry. Computer and mechanical engineers should cooperate in the design of basic measuring machines of advanced designs.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-8906Source: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyNotes: Conclusions 1. In the manufacture of high-quality products it is necessary to reject the application of fixed gauges and to test components by means of scale measuring instruments, with the exception of splined and threaded joints and small diameter holes, for which reliable scale instruments do not exist. 2. This changeover is necessary above all in the production of components to the second, first, and higher classes of precision, as well as in the cases when the permissible error in the shape is smaller than the tolerance for the size. 3. In observing technological processes it is advisable to have scale measuring devices instead of or in addition to fixed gauges, in order to be able to determine the true deviation of sizes from the tolerance boundaries. 4. In using fixed gauges it is necessary to provide sample testing of the geometrical-shape error, if it is specified to be smaller than the manufacturing tolerance for the size.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-8906Source: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyNotes: Conclusions 1. The error in measuring curvilinear surfaces is affected by two specific properties: the necessity of superposing the pointed tip on a given point of the surface and the variation of the angleγ between the measuring direction and the normal to the tested surface. 2. The root-mean-square subjective error in placing the measuring tip on the marked-out point of the surface increases from 0.004 to 0.13 mm with the angleγ rising from 0 to 47°. 3. With a rising angleγ between the line of measurement and the normal to the tested surface the measurement error increases, so that at angles above 37° many instruments fail to give stable readings owing to the jamming of their measuring stems. 4. For calculating contact deformations it is necessary to supplement the Hertz formula for the general case of a contact between two curvilinear surfaces by means of corrections for the angleγ and the moving force of the measuring tip along the surface. 5. Variation of the measuring force in the range from 15·10−2 to 2 N virtually does not affect the measurement error of static ary measuring devices. 6. A rise in the measuring force of portable measuring devices from 15·10−2 to 2 N increases the root-mean-square measurement error from 0.004 to 0.07 mm if the angleγ changes from 5 to 47°. 7. Increasing the tip radius rt from 0.5 to 2.0 mm and setting it by means of the marking-out method raises the root-mean-square measurement error by 50–100%; the error increases by a factor of 2–2.5 for rt=2.5 mm. 8. Raising the surface finish from Δ4 to Δ11-reduces the root-mean-square error on an average by a factor of two. 9. If in measuring curvilinear surfaces the measuring tip is locked, the measured surface is lubricated, or the measuring system is provided with artificial vibration, the measurement error can be reduced on an average by a factor of 1.5 for small anglesγ and by a factor of 0.2–0.85 for larger angles.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-8493Source: Springer Online Journal Archives 1860-2000Topics: TechnologyProcess Engineering, Biotechnology, Nutrition TechnologyNotes: Abstract The efficiengy of using diffeent inorganic catalytic additives in fabrication of carbon fibre mateials was evaluated by TGA. The important possibility of obtaining CFM with a high yield on the existing equipment at the Svetlogorsk Khimvolokno Industrial Association was demonstrated. The structure and properties of TS and NS carbon materials fabricated with the technology developed were investigated by methods of mercury porosimetry, electron microscopy, cryosorption of nitrogen, sorption of benzene vapors, and sorption of large organic ions. The possibility of using the developed carbon sorbents in purification of virus-containing solutions and for removal of organic contaminants from aqueous solutions was investigated.Type of Medium: Electronic ResourceURL: -
