摘要： HIGH OCTANE GASOLINE IS PRODUCED BY ISOMERIZING A C4 THROUGH C6 PARAFFIN FRACTION FROM A STRIAGHT RUN GASOLINE, THE HIGHER BOILING PORTION OF THE STRAIGHT RUN GASOLINE IS PASSED INTO A REFORMING ZONE. THE EFFLUENT FROM THE ISOMERIZATION ZONE IS PASSED INTO A MOLECULAR SIEVE SEPARATION ZONE WHICH SEPARATES NORMAL PARAFFINS FROM NON-NORMALS SUCH AS AROMATICS AND ISO-PARAFFINS. A PORTION OF THE EXTRACTED NORMAL PARAFFINS ARE THEN RECYCLED TO THE ISOMERIZATION ZONE TO EFFECT FURTHER PRODUCTION OF BRANCHED CHAIN PARAFFINS. THE RAFFINATE MATERIAL RECOVERED FROM THE MOLECULAR SIEVE SEPARATION ZONE IS SUFFICIENTLY HIGH IN OCTANE NUMBER TO BE UTILIZED AS A CLEAR GASOLINE. THE REFORMING AND ISOMERIZATION ZONE EFFECT THE CONVERSION OF THE RESPECTIVE FEED TO THOSE ZONES THROUGH THE USE OF SUITABLE CATALYTIC COMPONENTS. THE SEPARATION ZONE
UTILIZES A TYPE A CRYSTALLINE ALUMINOSILICATE TO SELECTIVELY EXTRACT NORMAL PARAFFINS FROM A FEED CONTAINING NORMAL PARAFFINS AND OTHER NON-NORMAL COMPONENTS.-

摘要： Compact ball joint assembly for piping system has ball and socket portions which may be formed of pipe. A reaction member held internally of the socket portion by retaining means such as a retaining ring or radially extending socket screws provides a support for a plurality of adjustment screws which can be moved in a direction parallel to the axis of the socket portion for forcing a pressure ring positioned for axial movement within the socket against a sealing ring which bears against the ball portion of the joint.
