Abstract: ABSTRACT One program in one address space is permitted to obtain access to data in another address space or to call a program in another address space without invoking a supervisor, with authorization to use a storage protect key other than that specifically assigned to the program by a supervisor program when in a new semi-privileged state.  Programs executing in a particular address space have supervisor assigned storage protect key masks permitting the program, when authorized, to utilize a storage protect key other than the one specifically assigned by the supervisor.  A second address space can be designated by a program, and when authorized, can cause transfer of data in main memory from one physical location to another associated with the different address space, and two different storage protect keys can be utilized.  A calling program can provide addres-sability to data in its address space by combining storage protect key masks from the calling program with a key mask of a called program to permit access to data by the called program.  Entering the called program causes the saving and changing of a problem/supervisor control bit and instruction address.

Abstract: ABSTRACT OF THE DISCLOSURE          Purification of gases from sulphur dioxide components according to the dry method means that the gas is contacted with an absorbent in a solid phase, which yields a relatively low reaction rate. In order to increase the reaction rate according to the invention, the gas is contacted with a mixture  consisting partially of a solid absorbent phase and partially a liquid phase on the  surface of the solid phase. At the purification of flue gases from sulphur dioxide hot gas is contacted with an absorption liquid in a drying apparatus, where evaporation of the water supplied and a reaction between sulphur dioxide and the absorption substance take place simultaneously, whereafter the solid product phase is separated from the gas in a dust separator and a slower, secondary absorption reaction is operative. In order to achieve a higher reaction rate in the dust separator, a substance is added to the flue gas which, together with other chemical species derived from the gas or the solid absorbent forms a liquid phase distributed over the surface of the solid phases. The liquid phase usually contains water and has a good solubility for reactants and reaction products.

Abstract: ABSTRACT          An improved peripheral processor architecture wherein the function controlling information of a program is separated from portions of the sequence of execution controlling information and each are stored in the form of tables.  The function controlling in-formation takes the form of a table including a plural-ity of function specifying entries.  The function execution sequence controlling information takes the form of a table of pointers.  In this invention, function controlling entries, each having a plurality of fields for defining, modifying, and specifying the functions and related data to be executed, need not be repetitively duplicated throughout the program. Instead, the shorter pointers to the function table entries can be provided in the sequence table in the sequence in which the functions are to be executed.          In a keyboard display controller application, further economy of storage is obtained by retaining a first level of function specifying information in the sequence table in the form of a bit identifying whether the function to be executed is a complex function, in which case the pointer identifies an entry in the function control statement table, or whether the function to be executed is merely the display of information on the display, in which case the pointer in the sequence table entry specifies an entry in a guidance table.

Abstract: ABSTRACT OF THE DISCLOSURE Gelation and setting of desirably miscible and pumpable aqueous crutcher slurries comprising zeolite (hydrated sodium aluminosilicate), so-dium bicarbonate, sodium silicate and sodium carbonate are retarded and often are prevented by the addition of sodium sesquicarbonate (which also serves as a source of sodium carbonate and sodium bicarbonate) after admixing of the zeolite, sodium bicarbonate, sodium carbonate (if added earlier) and sodium silicate.  Desirably, citric acid (and preferably also, magnesium sulfate) is (are) dissolved in the crutcher medium before addition of the sodium sesqui-carbonate but the presense(s) thereof is(are) not necessary.  The method of the invention appreciably increases workable crutcher time, stabilizing the mix against gelation, compared to prior methods for the manufacture of similar crutcher mixes of similar contents of water, zeolite, bicarbonate, carbonate and silicate (considering the sesquicarbonate of the present method as a source of carbonate and bicarbonate), whether all the carbonate and bicarbon-ate are separately added to the crutcher before the silicate are added par-tially before and partially after silicate addition.  The improved workability and stability of the crutcher mix permit the making of higher solids content crutcher slurries, thereby resulting in significant energy savings and in-creases in production rates when such slurries are subsequently spray dried to produce free flowing zeolite - inorganic salt base beads, from which beads built or heavy duty detergent compositions may be made by post-spraying onto them a nonionic synthetic organic detergent in liquid state.
