Abstract: PROCESS FOR PREPARING D-MANNITOL    ABSTRACT    A D-glucose solution is added molybdic acid compound thereto and heated at a temperature of 110 - 160 °C with pH 2.0 - 4.5 to perform epimerizing reaction of D-glucose, and thereby 30- 36 °%, based on the D-glucose, of D-mannose is formed.  To the epimerized mixture thus obtained is further added glucose-isomerase to per-form enzymatic isomerizing reaction of D-glucose remaining in the epimerized mixture, and thereby 46% based on the remaining D-glucose is converted into D-fructose.  The enzymatically isomerized mixture is subjected to catalytic hydrogenation under high pressure, and thereby is produced D-mannitol at   high yield based on the initial D-glucose.

Abstract: FIELD CORRELATOR                             ABSTRACT         A method and apparatus for correlating two time series of digital quantities comprising means for converting one of the time series to a sign bit series and means for algebraically summing values of the second series which occur at times corresponding to the zero crossings of the sign bit series.  The algebraic summation includes the modification of the signs of the summed values according to the direc-tion of the zero crossing which occurs in the sign bit series.  The preferred embodiment is a field correlator for use in geophysical seismic surveying to monitor data as it is recorded.  The field correlator converts a digitized pilot signal into a sign bit only series, which is then correlated to a digitized record of a geophone spread output by summing only those samples of the geophone outputs which correspond to zero crossings of the pilot signal for a given lag value.  As in standard correlation, the summation is repeated for each lag of the pilot relative to the detected signal so that an earth spikes trace is generated.

Abstract: ABSTRACT OF THE DISCLOSURE       This disclosure describes a process for the prepara-tion of iron-bearing and calcium-bearing sorbent solids for use in the desulfurization of gases.  The process involves mechani-cal procedures for generating porous agglomerated solids that are high in surface area and uniquely suitable in both particle size and mechanical properties for processing in gas-solids contacting equipment of conventional design.  The process also involves the use of water in the agglomeration procedures in quantities controlled to react both chemically and mechanically with solid components of the feed materials and to generate ad-hesive cement between finely divided solids in porous agglomer-ated particles of the sorbent product.  All components of the solid feed to the sorbent preparation process may be obtained from both finely divided new solids and solids obtained by re-cycle of regenerated solids from other sections of the combined process.  The selection of either iron-bearing or calcium-bearing solids for use in the process generally depends on the type of gas that is to be desulfurized, and on both the total demand and the net cost of the new solids required by the com-bined process,  Iron-bearing sorbents are significantly less costly to regenerate than calcium-bearing sorbents, and gene-rally are preferred for most industrial uses.  When iron-bear-ing sorbents are utilized in the desulfurization of fuel gases at temperatures above 750°C, magnesium and/or aluminum bearing diluent materials are employed as components of the new feed to the sorbent preparation process.  These diluents, when con-verted to refractory oxides in agglomerated particles of the sorbent solids by procedures of the combined process, eliminate the tendency of these solids otherwise to fuse, to agglomerate, and to defluidize in contact with the hot gases in desulfuriza-tion absorber equipment.
