Abstract: S P E C I F I C A T I O N     TO ALL WHOM IT MAY CONCERN:         BE IT KNOWN that we, HAROLD E. KNOWLTON and RAYMOND A.      PETRICK, citizens of the United States of America and residents, respectively, of Moraga, County of Contra Costa, State of California, and Ocean Springs, County of Jackson, State of Mississippi, have invented new and useful improvements in CLEANING METHOD FOR REFINING PROCESS RUNDOWN TANK   of which the following is a specification:                   ABSTRACT OF THE DISCLOSURE         A method is described for cleaning nonsettling oil-solid mixtures from the bottom of catalytic cracking rundown tanks wherein a solvent of particular specifications is introduced in the rundown tank and circulated around, in and through the non-settling oil solids with an angularly adjustable pumping means.          After the floating oil-solid mixture has been separated by the sol-vent, the solvent and liquid are removed from the tank, separated and recycled to process streams.  The remaining settled solid sedi-ments may then be washed with an aqueous solution circulated in the tank with the adjustable pumping means to water-wash addi-tional oils from the solid sediments, and the aqueous solution and oils carried therewith are removed from the tank and separated.         The remaining solid materials are then vacuumed from the tank or water-washed from the tank to complete the cleaning process totally from outside of the tank.

Abstract: TEMPERATURE COMPENSATING HYDRAULIC JARRING TOOL Abstract of the Disclosure A hydraulic jarring tool is provided that vents pressure slowly from the tool's internal operating fluid chamber to allow maximum filling of the tool prior to the tool's entering a well and to provide for operating fluid expansion with temperature increases.  The jarring tool includes an outer member and an inner member telescopically arranged.  Spline means between said outer member and said inner member transmit torque.  A hammer and anvil system provide a jarring effect upon actuation of the tool.  An operating fluid is maintained in an operating fluid chamber between the outer and inner members.  Seal means between the outer and inner members provides a fluid seal to contain the operating fluid.  The seal means includes a seal and thermal relief valve assembly mounted for axial travel between said inner member and said outer member with a passage extending therethrough.  A thermal relief valve means in the passage provides pressure equalization.  The thermal relief valve means provides a controlled flow of operating fluid from the operating fluid chamber to relieve excessive fluid pressure without undue loss of operating fluid.

Abstract: Case 790429 FAULT INDICATOR WITH MAGNETIC TEST POINT Edmund O. Schweitzer, Jr. Abstract of the Disclosure A fault indicator for use in conjunction with components of a power distribution system contained within a protective enclosure includes a magnetic test point on the exterior surface of the enclosure for indicating the occurrence of a fault in associated circuits of the system. The fault indicator includes a circuit module mounted on a conventional test-point provided on one of the system components, and a magnetic indicator module mounted on the wall of the enclosure. The indicator module includes a magnetizable element which extends through the wall of the housing to provide a magnetic test point. Upon occurrence of a fault in the system, circuitry within the indicator module energizes a first winding in the indicator module to establish a magnetic state of a first polarity at the test point. Upon restoration of power, a reset circuit energizes a second winding to establish a magnetic state of opposite polarity at the test point. A portable test instrument comprising a hand held housing on which a magnetized flag member is rotatably mounted is positioned adjacent the magnetic test point by a lineman to determine circuit status.
