  • Patent number: 4569749
    Abstract: A process for the liquefaction of coal wherein raw feed coal is dissolved in recycle solvent with a slurry containing recycle coal minerals in the presence of added hydrogen at elevated temperature and pressure. The highest boiling distillable dissolved liquid fraction is obtained from a vacuum distillation zone and is entirely recycled to extinction. Lower boiling distillable dissolved liquid is removed in vapor phase from the dissolver zone and passed without purification and essentially without reduction in pressure to a catalytic hydrogenation zone where it is converted to an essentially colorless liquid product boiling in the transportation fuel range.

  • Patent number: 4560721
    Abstract: A novel ether solution of dinitrobenzophenone and a process for preparing an ether solution of diaminobenzophenone therefrom which comprises subjecting a dinitrobenzophenone dissolved in said ether solvent to hydrogenation in contact with a continuous nickel catalyst to obtain said solution of diaminobenzophenone dissolved in said ether solvent. In a specific embodiment said nickel catalyst is mounted on an inert support. In a still further embodiment, said diaminobenzophenone dissolved in said ether solvent, after removal of water therefrom, is reacted with an aromatic dianhydride to obtain a polyamic acid solution. The polyamic acid solution can be heated at a temperature above 100.degree. C. to drive off water of cyclization and thereby obtain the corresponding polyimide resin.

  • Patent number: 4558438
    Abstract: In a system for displaying geophysical information on a video screen, data representative of spaced subsurface strata are stored in a computer memory. The data are extracted, plane by plane, and data bytes representative of the planes are stored in pairs in memories in an image processor. The data representative of one plane is displayed and recorded on a medium such as video tape. An image is then formed using a large fraction of the value of the data representative of one plane and a smaller fraction of the data representative of the next plane, and that image is stored. Successive images are formed using decreasing fractional amounts of the data representative of the first plane and increasing fractional amounts of the data in the next plane. Each image is stored and displayed, the display presenting a sequence of images which appear to merge or dissolve smoothly from one to the next. The process is repeated through all stored strata.
