  • A method of evaluating the dynamic response of materials to forced oscillation
    …extension block is long enough and made of a material which has sufficiently small heat conductivity and sufficiently high stiffness, such as a ceramic , the rest of the apparatus, including the aerostatic linear bearing , can be placed outside the constant- temperature box. .
  • The Electrical Measurement of Pressures and Indicator Diagrams
    Here, the diaphragm bears upon a block of carbon, or certain ceramic materials, whose resistance decreases under compression, arranged … e.m.f. may not be a linear function of load, and … themselves also suffering from high - temperature coefficients and liability to…
  • An Automatically Recording Electrical Sorption Balance
    Here, the diaphragm bears upon a block of carbon, or certain ceramic materials, whose resistance decreases under compression, arranged … e.m.f. may not be a linear function of load, and … themselves also suffering from high - temperature coefficients and liability to…

  • A Comparison of Spindle Ball Bearings with Steel or Ceramic Balls for Very High Speed Applications
    A frequent cause of failure of spindle ball bearings is the loss of the entire radial clearance .... In the case of a ceramic ball, the smaller linear thermal expansion coefficient permits a larger temperature difference between the inner and outer rings and, as a result, a higher degree of reliability results (Fig. 13).
  • Analysis of the status and prospects for the commercial use of fiber-reinforced silicon-carbide ceramics
    Ceramic composites can be used to make nozzles and their components, sprayers, gas burners, heat shields, grates, heat-exchanger components and parts of foundry gates, electrodes for arc furnaces, fire-protection hoods, rollers, bearings , heaters, press molds, slide gates, thermocouple jackets, stirrers .... Also, since their coefficient of linear expansion is almost zero, CCMs can be used to make equip- ment employed in precision casting (crucibles, molds) or high - temperature soldering, such as for automotive heat exchangers.
  • Proposal for material viscoelasticity evaluation method under impact load
    If the material under test is put in a constant temper- ature box, the temperature dependency of the material characteristics, which is especially important for high molecular weight materials materials, can be evaluated using the proposed method. .... In this case, if the exten- sion block is long enough and made of a material, such as a ceramic , which has insignificant heat conductivity and large stiffness, the rest of the apparatus including the pneumatic linear bearing can be placed outside…
  • Modeling and Identification of the Processes of Heat Exchange in Porous Materials of Thermal Protection of Reusable Aerospace Systems
    By virtue of the pronounced difference in the thermal coefficients of linear expansion of the material of the bearing frame and the high - temperature heat insulator, the tiles are stuck to the bearing frame by means of damping substrates from fibrous material. .... However the ceramic tiles covering about 70% of the Space Shuttle and Buran area have a number…
  • Co‐operative study on the release of lead from crystalware
    …with lead release correlated with the time square root by means of a linear regression equation in .... The data available in the literature on lead release from silicate surfaces in contact with food or simulants almost exclusively refer to studies on ceramic glazes or enamels5–8 and the … as it melts at much higher temperatures than do lead- bearing glazes.
