Abstract: An odorless sterilizing and disinfecting solution containing 0.025 to 1.0 weight percent phthalaldehyde.

Abstract: A sterilizing and disinfecting solution is disclosed. The solution contains a saturated dialdehyde such as glutaraldehyde and an aromatic dialdehyde, such as phthalaldehyde, isophthalaldehyde or terephthalaldehyde.

Abstract: This invention relates to a method and apparatus for measuring the optical power of soft contact lenses having a lens holding apparatus which is mountable on known prior art lensmeter structures. The lens holding apparatus includes a basic support housing means, a lens holder assembly mounted on the basic support housing means, and a lens conditioner means connected to the basic support housing means and operably engagable with the lens holder assembly. The lens holder assembly includes a contoured lens support member having a transparent lens support surface to substantially duplicate the outer contour and size of a person's eye. The lens conditioner means includes a lens wiper assembly operable through an actuator linkage assembly to move a wiper blade member over the contoured lens support member with a soft contact lens mounted thereon to provide a wetting action on both sides of the soft contact lens to duplicate the conditions when worn on the cornea of a person's eye.

Abstract: This invention is a revolving examination table apparatus to be used by, for example, optometrists during eye examination to place a desired instrument between the patient and the doctor. More particularly, the table apparatus includes (1) a main, circular support base assembly; (2) a revolving table top assembly rotatably mounted on the support base assembly; and (3) an electrical control and drive assembly operable to control rotation of the revolving table top assembly. A central portion of the support base assembly and the revolving table top assembly is cut out to receive a chair and person (optometrist) therein while the patient sits opposite therefrom with the table apparatus therebetween.

Abstract: Tertiary phosphine oxides are reduced to the corresponding phosphines by halosilanes in the presence of a stoichiometric amount of a primary or secondary amine. The reduction in yield expected using a primary or secondary amine in place of the prior art tertiary amine is not observed.
