The process includes charges spent catalyst vertically downwards into a lower regeneration zone and an oxygen containing primary regeneration gas is passed under turbulent flow upwards through the lower regeneration zone and into the bottom of an upper regeneration zone,  The oxygen-containing primary regenera-tion gas contains about 25 to 40 percent of the stoichiometric amount of oxygen required for combusting coke spent catalyst.  An oxygen-containing secondary gas is supplied radically to the bottom of the upper regeneration zone and contains about 60 to 85 percent of the stoichiometric amount of oxygen required for combusting coke on spent catalyst, the total amount of oxygen provided being from 100 to 110 percent of the stoichiometric amount required.  A fluidized dense phase bed of catalyst undergoing regeneration is maintained, from the upper portion of which hot regenerated catalyst is removed.  Additionally a method is provided for transferring heat from a dilute phase back to the fluidized dense phase catalyst bed.

Abstract: Abstract of the Disclosure Alkali metal aluminate solutions are subjected to two-stage carbonatation with stirring to produce alum-inium hydroxide, a gallium-containing precipitate, and solutions containing caustic and alkali metal bicarbonate.          Thereafter the produced gallium-containing precipitate is mixed with a solution containing caustic alkali until the content of gallium in the solution is 0.05 to 1 g/l.  Any precipitate formed is separated and the solution enriched with gallium is mixed with a solution containing alkali metal bicarbonate.  The resulting mixture is subjected to evapora-tion to separate alkali metal compounds, and the solution which has been subjected to evaporation is carbonated to produce a solution containing alkali metal salts, and a gallium concentrate from which gallium is produced by trans-forming it into an alkaline solution from which metallic gallium is recovered, either electrochemically, such as by electrolysis, or by reduction with an aluminium-containing gallium alloy.  The proposed method makes it possible to extract gallium at a comparatively low cost from solutions obtained in the processing, for example, of nephelines containing it in amounts which do not exceed 0.02 to 0.03 g/l.  As a result of the proposed method, it has become possible in the processes of concentration of gallium to produce a number of valuable components such as alkali metal salts contained in the starting ore.

Abstract: 191-Canada ABSTRACT OF THE DISCLOSURE          Heretofore the digital display indication of weight loaded on a weighing scale has automatically decreased the resolution of the indication by at least one decimal place on switching from a fine to a coarse measurement range.  This change in range is dependent on the total load applied to the scale, hence display indications after taring inherently lack at least one significant digit relative to the fine indication.          A digital display is provided by which, at any selected point within a coarse measurement range, a control means may be actuated for switching to the starting point of the fine measure-ment range, as when weighing a component added to a previously-loaded component: the indication may thereafter be changed to read the total load weight in the coarse measurement range.  Preferably, the control means are connected to the tare key for actuation therewith.

Abstract: Abstract A set of four cell suspensions containing erythrocytes monospeci-fically sensitized with IgG, IgM, C3, and C4.  The suspensions provide control cells to determine the purity and strength of the antibodies to these immunoglobins or complement components contained in antisera used for clinical testing.  Strict control of the pH, temperature, and EDTA concentration of a solution to which blood is added allows for the elective production of C3- or C4- sensitized cells.  Selecting a serum with IgG or IgM antibodies and inactivating undesired proteins permits the production IgG- or IgM-sensitized cells.  The resultant cells have agglutination reaction strengths of about 2-4+.  Erythro-cytes from humans or other animals may undergo the monospecific sensi-tization.  Other human proteins, such as IgA or CS, and plasma proteins from other animals may similarly be attached monospecifically to red blood cells.
