A copper base insert coated with a layer of aluminum oxide ceramic prevents frictional binding between the gate and base surfaces of a gate valve which are subject to rapid sliding action and high temperatures.
Theory of solar wind as hydrodynamic expansion of outer corona due to gravitational binding and thermalization
Fabrication techniques for high temperature thermocouples bind all components so that differential thermal expansion and contraction do not result in mechanical slippage and localized stress concentrations. Installation space is reduced or larger thermoelements and thicker insulation can be used to improve temperature measurement accuracy.
Field emission of cesium ions from positive electrode formulated for electric field range that binds ions to electrode surface
Major axes distribution of long period comets, stressing number distribution and binding energy
Level structure of hydrogen isotope of mass four, determining binding energies and widths
Scattering of neon, argon and xenon from silver surfaces, discussing values of interatomic binding energy
Spherical depressions on the wall of the inner tube increase the heat flux in a concentric tube heat exchanger. Regularly spaced patterns of precisely formed depressions on the inner wall alleviate the film-binding phenomenon without significantly degrading the flow characteristics.
One-shot, breakaway multiwire cable connector is fabricated by using a number of small-diameter interconnecting wires, each of which, differing incrementally in length, is welded to neighboring pin and cable terminations. This design eliminates frictional binding and provides highly reliable cable interconnections until the connector is disengaged.
Rhenium effect on lattice solid solubility of oxygen in tungsten, calculating rhenium-oxygen cluster minimum binding free energy
Approximate ionization potentials for high ionization stages of elements with atomic numbers 31 to 92 obtained by binding energy calculations
DNA and d/A-T/ oligomers enzyme binding to DNA polymerase by sucrose density gradient centrifugation
Elastic electron scattering by metastable states of rare gases, using effective potential matching experimental binding energy of negative ions
Flow liner eliminates high-cycle fatigue in ducts carrying cryogenic fluids. It is capable of handling two-directional, high-velocity cryogenic liquid flow with a 3-inch axial motion without binding within a 25-inch length.
Nonequilibrium and equilibrium schemes studies of nuclear symmetry energy of finite nuclei, discussing binding energy of nuclei with neutron excess
Liner for hybrid solid propellants to bind propellant to rocket motor case
Computations of binding energies and vibrational energies of ground state molecular hydrogen to measure accuracy of dissociation energy
Variation method, and binding energy and structure of atoms and molecules
