Abstract: Abstract The invention relates to an improvement in apparatus for carrying out the submerged arc surfacing of metallic work pieces with metal electrode strips melting in an electric arc while forming welding beads upon the work piece.  A slag breaker comprising a series of parallel plate portions disposed substantially perpendicular to the surface of the electrode strip is positioned on the leading side of the electrode strip adjacent the region of the electric arc.  The slag breaker serves to break up an accumulation of fused flux particles which tend to form a sheet in front of the welding arc which, if permited to form would block the flux feed into the welding arc on the leading side.  The slag breaker thus serves to prohibit formation of such a sheet and thereby permits uniform flow of flux to insure complete submergence of the arc in the flux material thus minimizing the chance of the arc flashing through the flux burden and resulting in defects in the deposited cladding material.

Abstract: PROCESS FOR PREPARING DIISOPROPYL ETHER     Abstract of the Disclosure Diisopropyl ether is prepared from isopropanol in liquid phase in contact with particular Montmorillonite clay catalysts, optionally in the presence of added propylene.  The process is operated in a continuous manner by continuously feeding liquid isopropanol, optionally with added propylene, into a reaction space where the feed contacts the catalyst at 120°C to 250°C for an average contact time of 1 to 120 minutes.  Pressure is maintained in the reactor to keep a liquid phase in contact with the solid catalyst.  Effluent withdrawn continuously from the reaction space at the feed rate is separated by fraction-ation to recover diisopropyl ether.

Abstract: ABSTRACT OF THE DISCLOSURE           Device for selectively positioning one portion of a two-color ribbon between a document-supporting platen and a print head having printing members which are selectively impacted against the desired ribbon and the document, said device comprising a color-select solenoid energized by logic circuitry activated by a print-color signal.  The solenoid is energized to move to a first position to enable characters of a first color to be printed at selected positions along a line.          The logic circuitry selectively omits the performance of a line feed, and delays the generation of print enable and print head movement signals for a time interval sufficient to allow for the color select solenoid to move the ribbon to the opposite color position at which time the characters of the opposite color are printed.  A modification of the logic circuitry enables a dot-matrix impact printer capable of printing in both the forward and reverse directions to print a single line of intermixed characters of first and second colors in a somewhat similar fashion.
