A process for preparing 2-methyl-1-cyclohexanol with high stereoselectivity and high yield by reacting 2-methyl-cyclohexanone in a Grignard reaction with a Grignard compound of 3-bromoanisole in a suitable solvent and in the presence of an inorganic lithium salt and an \u03b1,\u03c9-dialkoxyalkane. Interior surfaces are enhanced in size by projections defined by deformation in sidewalls of the photopanels. Respective percentages of a selected emission time are calculated for each current density to produce a designated luminance and chromaticity. This strip is tensioned when the cover is unwound from the spool and a locking mechanism retains the cover in a desired unwound position against the tension of the rubber strip.
