    摘要： The invention contemplates improved extraocular-lens structures for contact with the cornea of a human eye, to be worn in place of spectacles. The construction features a lens element of requisite prescription power but of diameter which substantially equals or only slightly exceeds the fully dilated pupil size of the wearer, and fenestrated haptic structure engaged to the lens extends radially outwardly and is so thin and axially compliant as to be self-conforming to the curvature of the cornea and to effectively adhere thereto, thus stabilizing the lens for retention of its position on the optical axis of the eye.

    摘要： The monourea adduct of sulfuric acid, when combined with water, has the unique ability to ablate the surface of wooden articles without charring or otherwise disfiguring the surface of the wooden article. Thus, wooden articles can be treated to accomplish a variety of purposes by contacting the surface to be treated with a composition containing the monourea adduct of sulfuric acid. Such compositions comprise mixtures of urea and sulfuric acid in which the molar ratio of urea to sulfuric acid is within the range of 1/4 to about 7/4 so that at least about 25 percent of the sulfuric acid is present as the monourea adduct. Such treatment can be employed to modify the dimensions of the article surface, remove stains, mars or other markings, accentuate the hard grain of the article surface, emboss the surface with a predetermined pattern, or accomplish other objectives that result from generally or selectively ablating the article's surface.
