Abstract: High surface purity heat transfer solids are formed, suitably by washing and treating particulate refractory inorganic solids, notably alumina, which contains as impurities up to about 0.5 wt% silicon and/or up to about 500 wppm boron, with an acid, or dilute acid solution sufficient to reduce the concentration of silicon and boron in the outer peripheral surface layer of the particles, e.g., as measured inwardly toward the center of a particle to a depth of about 50.ANG. using X-ray photoelectron spectroscopy, to no greater than about atom % silicon and boron, preferably about 2 atom % silicon and boron, based on the total number of cations within said outer peripheral surface layer, thereby reducing the tendency of said particles to sinter and agglomerate in the conversion of said hydrocarbon to hydrogen and carbon monoxide in a fluidized bed synthesis gas operation vis-a-vis particles otherwise similar except that the particles are not treated with the acid. The tendency of the particles to sinter and agglomerate is further reduced by the additional removal of sodium, iron, calcium, and titanium impurities from the outer peripheral surface layer of the particles. Preferably the latter named impurities, or impurities other than silicon and boron, are reduced to a concentration below about 20 atom %, more preferably to a concentration below about 15 atom %, in the outer surface layer of the particles.

Abstract: Electric apparatus responsive to currents and/or voltages having wide dynamic ranges incorporates ranging circuits for each input in which a multiplexer providing the ranging selection has a common input connected to the output of an operational amplifier providing the selective gain and has a plurality of outputs connecting selected ones of a plurality of series connected precision resistors in a feedback loop around the operational amplifier. A second operational amplifier is connected as a follower to the last output of the multiplexes so that the gain applied to the output signal is not distorted by the resistance of the switches in the multiplexer. For three-phase systems not having a neutral conductor, phase to neutral voltages with ranging are generated by subtracting a neutral-to-ground voltage produced from an artificial ground created by connecting three resistors in a wye across the phase conductors from the phase-to-ground voltages applied to the ranging circuit input.

One such sequence can be obtained by screening a genome bank containing the chromosome DNA of a branch of H. pylori with the above specillum, recuperating the DNA sequences that hybridise with the specillum, sub-cloning the DNA sequences obtained in an appropriate plasmide-type vector and selecting modified vectors that hybridise in conditions of great stringency with the specillum.

Abstract: Vibrations are dampened by determining two principal frequencies of excitation for the structure and coupling thereto a damping member to produce an absorber. The spring damper characteristics of the absorber are determined at these frequencies and the displacement of the damping member is monitored. The monitored displacement of the damping member is processed together with the spring damping characteristics of the absorber to output a signal. This produces two frequencies of vibration in the damping member substantially equal to the determined frequencies of excitation and thereby produces a resonance of the damping member at the determined frequencies of excitation. The resonance is effective to damp the vibrations at the determined frequencies of excitation.
