Abstract: Examples include techniques for memory scrubbing associated with reliability, availability and serviceability (RAS) features. Examples include obtaining error correction code (ECC) encoded data stored in a physical memory unit maintained in a physical memory device in associated with a memory scrubbing operation. Examples include correcting detected errors in ECC encoded data and cause the corrected or scrubbed ECC encoded data to be stored in the physical memory unit. Examples include obtaining the scrubbed ECC encoded data from the physical memory unit and responsive to at least one detected error in the scrubbed ECC encoded data, trigger one or more RAS features.

Abstract: An arrangement for charging an electric arc furnace with a relatively free-flowing charge of sponge iron or other iron-containing particles distributes the charge of particles within the furnace through a first chute before a melting stage of an electric arc steelmaking operation is begun, and then continuously through a second chute which extends through the roof of the furnace during the melting stage. The first chute extends from a hopper containing the sponge iron and can be moved when the roof is open to feed the charge into the furnace. A distributor cone at the lower end of this chute distributes the sponge iron in a predetermined pattern. A second chute affixed to the furnace roof and in communication therethrough with the interior of the furnace permits continuous charging of the furnace during operation.

Abstract: In a process of extraction involving the use of solvents, considerable increase is obtained in the effective load of the extraction phase and in the recovery factor, through a new combination of the reactors employed in order that the loading and unloading stages of the organic phase may alternate.
