    • Compositions of matter are provided comprising a stable, non-vaporous monomeric methylene base selected from a 2-methylenethiazoline; a 2-methylenebenzothiazoline; a 2-methylenenaphthothiazoline; a 2-methylenebenzoselenazoline; and a 2-methylenenaphthoselenazoline. The compositions of the invention are prepared by reacting the parent 2-methyl quaternary salt with a non-hydroxylic base which removes a proton of the heterocyclic salt together with a proton acceptor which inhibits build-up of the hydro salt of the non-hydroxylic base, the reaction being conducted under anhydrous conditions in a non-hydroxylic liquid in which the heterocyclic quaternary salt is sufficiently insoluble to inhibit dimer formation. The compositions of the invention are employed in the preparation of methine dyes.

    • A tape measure comprises a main case having first and second sidewalls and a peripheral wall extending between the sidewalls; a flexible tape blade selectively deployable from the case; the tape blade having a generally curved cross-sectional profile when deployed from the main case and having a generally flat profile when retracted into the main case; a hook attached to a first end of the tape blade so as to be movable a distance along a longitudinal axis of the tape blade; the hook having a first section disposed generally parallel to the longitudinal axis and a second section connected thereto and disposed generally normal to the longitudinal axis, the hook comprising titanium and having a weight factor of not more than about 0.60. The tape blade may advantageously be not more than about 1.10 inch in width and have a standout of at least 9½ feet.
