Water based waxing mixtures for protecting surfaces providing ionically neutral ingredients adhering to the surface while repelling environmental impurities, such as dirt. Surface precleaning need not precede the wax application because of an exchange, which takes place between the mixture and surface dirt. The mixture constitutes an emulsion of an organic phase in an aqueous phase. The aqueous phase amounts to 70 percent to 92 percent by weight, while the organic phase provides the remainder of...

The present invention relates to a method and apparatus for positioning a tapered member so that the taper of a tapered surface thereof can be verified. The apparatus comprises a first surface having an angle with respect to the horizontal which is equal to the included angle of the shaft to be measured. A vertical surface having an angle equal to one half the included angle of the shaft to be measured is arranged along one edge of the first surface. A plurality of horizontal gauge block surface...
