Abstract: A clip type nut device for attachment about an aperture or opening of a support structure is provided with the clip nut device having a resilient main body member having a pair of transversely oppositely extending bushings at opposite ends of a flexible strap with a captured nut member in one bushing. One bushing has a first opening and is receivable within the support structure opening. The other or second bushing has a second opening with the threaded nut member captured in the second opening. A securing structure associated with the first and second bushing is operable to secure the first bushing to the second bushing with the first opening being aligned with the second opening such that the threaded nut member is aligned with the opening through the support structure.

Abstract: Water Repellent compositions including a silico-titanium polymer, a cationic, surface-active quaternary ammonium compound, and a spreading agent which provides odor detection properties.

Abstract: An aluminum alloy article is anodized in an aqueous solution of phosphoric acid. Oxide forms on the surfaces of the article and dissolves as it forms to displace contaminants and deoxidize the surfaces. The anodizing etch rate is from about 0.0002 to about 0.0005 inch/surface/hour. Residual oxide on the surfaces is a maximum of about 3000 Angstroms. The article may be left in the solution following anodizing to dissolve a portion of the residual oxide. Preferred anodizing parameters include 15 to 25% by weight phosphoric acid, 75.degree. to 95.degree. F., and 4 to 10 volts. Usual anodizing times are from 5 to 10 minutes. Following deoxidation, the article is ready for subsequent processing, such as anodizing to provide a controlled thickness porous oxide coating followed by adhesive bonding.
