  • Patent number: 4135598
    Abstract: Apparatus for truck-mounting of vibrational seismic energy transducers, particularly shear wave transducers, that provides improved vibrational damping and energy coupling into the earth. The apparatus consists of a four column, hydraulically actuatable suspension system operative from the truck or carrier frame as opposite side pairs to support a box frame under which the vibrator and earth coupling assembly is supported by a system of lateral and vertical springs. The vibrator assembly is entirely supported by means of left and right transverse springs to transmit reactive forces resulting from isolation through the box weldment and four columns to the vehicle body. Thus, the vibrator and its associated base plate structure is entirely supported from the vehicle and positioning assembly by resilient means having the requisite interactive constants.

  • Patent number: 4134821
    Abstract: A coal liquefaction process is provided in which a solvent is used to at least partially liquefy the coal. The process is maintained in solvent balance without extraneous addition of make-up solvent. The required balance is effected by selectively recovering from the liquefaction product an oil-containing liquid phase, at least a portion of the liquid phase being thereafter hydrogenated to form coal solvent in sufficient amount to replenish that lost. The selective recovery of the desired liquid phase is effected by means of a deasphalting solvent that preferentially separates asphaltenes and benzene insolubles from the coal extract.

  • Patent number: 4128405
    Abstract: A method for adsorbing VCM from vapors through the use of incompletely dried activated carbon under essentially adiabatic conditions allowing most of the VCM to adsorb on carbon having water previously adsorbed, the heat of adsorption of VCM desorbing the water instead of heating the carbon bed. The VCM adsorption is greater than that found on a dry bed when an adiabatic temperature rise is allowed to occur on the dry bed. A portion of the carbon bed can be kept dry if necessary to reach desired VCM levels. The advantage of the invention resides in adsorbing greater amounts of VCM per pound of carbon used, less drying necessary after regeneration, and less likelihood of high temperature deleterious reactions occurring.

  • Patent number: 4126750
    Abstract: High pressure methylation of 2,6-xylenol to produce 2,3,6-trimethylphenol is accomplished by maintaining the methanol/2,6-xylenol feed at temperature and pressures sufficient to keep the feed liquid in a reactor head then forcing the feed through orifices, expanding the feed into a mixed vapor liquid phase, the feed after expansion being in the range of reaction conditions of pressure and temperature while in the presence of the catalyst where the reaction takes place. The process avoids the current problems of uneven feed mixtures and catalyst tube plugging.

  • Patent number: 4125736
    Abstract: This invention provides an improved process for the disproportionation of highly alkylated phenols with phenol using an improved magnesium oxide catalyst promoted with tungsten oxide, silica sol, and sodium silicate. The method provides a catalyst having a high reactivity, high surface area, and high crush strength compared to known magnesium oxide, tungsten oxide catalysts. The catalyst is useful in phenol methylation and disproportionation. The effect of silica sol and sodium silicate is synergistic since these materials alone will not catalyze these reactions. Surprisingly, the catalyst will not disproportionate olefins.
