Abstract: Method and apparatus are provided for efficient metal distillation, and for related primary product process. Vertically stacked and gravity-driven evaporators and condensers are employed to distill metals, such metals having different volatilities. A multiple-effect thermal system of magnesium and other volatile metals is used to efficiently distill and separate metals from multiple metal alloys.

Abstract: One embodiment provides for a media playback device comprising a memory device to store instructions; one or more processors to execute the instructions stored on the memory device, the instructions to cause the one or more processors to provide a playback queue manager to manage one or more media playback queues including a set of media items associated with a scheduled event and a playback routing manager to determine an output destination for the set of media items based on context associated with the scheduled event, the playback routing manager to route output of playback of the set of media items to one or more of multiple different connected media playback devices based on the context associated with the scheduled event.

Abstract: An organic phosphor which is a solid insoluble in water and organic solvents and which may be used in a phosphorescent printing ink or a paper coating composition comprises molecules of at least one phosphorescent activator held within a matrix of a condensation resin that does not itself absorb ultraviolet or visible radiation at the excitation and emission frequencies of the phosphorescence activator(s). The phosphorescence activator(s) is/are a compound or mixtures of compounds of the general formula(A).sub.m --Ar--CO--X (I)wherein Ar denotes a fused ring polycyclic aromatic group;m is zero or an integer of from 1 up to the maximum number of ring positions available for substitution;X denotes an alkyl group or a group of the formula (A).sub.m --Ar-- or (B).sub.n Ph--wherein Ph is a phenyl group and n is zero or an integer of from 1 to 5; andA and B represent ring substituents, or an acid addition salt thereof when said compound is basic.
