Any good anagrams for lever rule?

In chemistry, the lever rule is a formula used to determine the mole fraction (xi) or the mass fraction (wi) of each phase of a binary equilibrium phase diagram. It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.In an alloy or a mixture with two phases, α and β, which themselves contain two elements, A and B, the lever rule states that the mass fraction of the α phase is w α = w B − w B β w B α − w B β {\displaystyle w^{\alpha }={\frac {w_{\rm {B}}-w_{\rm {B}}^{\beta }}{w_{\rm {B}}^{\alpha }-w_{\rm {B}}^{\beta }}}} where w B α {\displaystyle w_{\rm {B}}^{\alpha }} is the mass fraction of element B in the α phase w B β {\displaystyle w_{\rm {B}}^{\beta }} is the mass fraction of element B in the β phase w B {\displaystyle w_{\rm {B}}} is the mass fraction of element B in the entire alloy or mixtureall at some fixed temperature or pressure.
