Abstract: A process is described for the continuous thermal cracking of hydrocarbon oils, which process comprises heating a hydrocarbon oil feed, introducing the hot feed into a soaking vessel having its interior divided into a plurality of consecutive, interconnected compartments, and causing hot liquid to pass through the consecutive compartments prior to withdrawal of liquid material from the soaking vessel. The gas present in each compartment is collected and is separately withdrawn from the soaking vessel.

Abstract: This invention relates to an improved process for the production of liquid carbonaceous fuels and solvents from carbonaceous solid fuels, especially coal.The claimed improved process includes the hydrocracking of the light SRC mixed with a suitable hydrocracker solvent. The recycle of the resulting hydrocracked product, after separation and distillation, is used to produce a solvent for the hydrocracking of the light solvent refined coal.

Abstract: An automated apparatus for the solvent separation of a coal liquefaction product stream that operates continuously and unattended and eliminates potential errors resulting from subjectivity and the aging of the sample during analysis. In use of the apparatus, metered amounts of one or more solvents are passed sequentially through a filter containing the sample under the direction of a microprocessor control means. The mixture in the filter is agitated by means of ultrasonic cavitation for a timed period and the filtrate is collected. The filtrate of each solvent extraction is collected individually and the residue on the filter element is collected to complete the extraction process.

Abstract: A perio-dontal surgical instrument is disclosed which includes a handle, shank and a cutting head. The cutting head possesses two interior surgical blades each possessing terminus points having their confluence at a substantial V-shape to form an apex. At least one exterior surgical blade is positioned on the cutting head with its beginning at a first point substantially equal to the terminus of one of the adjacent blades. A method of use is also described for this perio-dontal surgical instrument for Gingivectomy and Gingivoplasty operations.
