20130047411 | Temporary Rivet - A temporary fastener and method, the fastener having a cylindrical sleeve and a sleeve head thereon, the region where the sleeve and sleeve head mate having a plurality of local protrusions thereon, with a stem passing through the sleeve head and sleeve and having an enlarged stem head adjacent the end of the sleeve opposite the sleeve head for pulling relative to the sleeve head to cause the enlarged stem head to form a blind side head on the sleeve and to cause the local protrusions to make depressions in an outer edge of the hole, and to pull through the sleeve and sleeve head to expand the sleeve into a tight fit in the workpieces. The protrusions make indentations in the edge of the hole in the adjacent workpiece to provide increased resistance to spinning when the temporary blind rivet is drilled out for a permanent fastener. | 02-28-2013 |
20120034045 | Temporary Rivet - A temporary fastener or temporary blind rivet having a cylindrical sleeve and a sleeve head thereon, the region where the sleeve and sleeve head mate having a plurality of local protrusions thereon, with a stem passing through the sleeve head and sleeve, the stem having an enlarged stem head thereon adjacent the end of the sleeve opposite the sleeve head, the stem for pulling relative to the sleeve head to cause the enlarged stem head to form a blind side head on the sleeve, to pull the workpieces together, to cause the local protrusions to make depressions in, and to fill the depressions in, an outer edge of the hole in the adjacent workpiece, and to pull through the sleeve and sleeve head to expand the sleeve into a tight fit in the hole in the workpieces. The protrusions make indentations in the edge of the hole in the adjacent workpiece to provide increased resistance to spinning when the temporary blind rivet is drilled out for a permanent fastener. | 02-09-2012 |
20110300406 | PAINTED METAL PARTS WITH NON-HEXAVALENT CHROMIUM CHEMICAL CONVERSION COATING AND PROCESS - A method including forming a first layer comprising a non-hexavalent chromium chemical conversion coating on a metal surface; and forming a second layer on the first layer through a sol gel process. An apparatus including a metal component having at least one surface; a first layer comprising a chemical conversion coating on the at least one surface; and a second layer derived from a sol gel composition on the first layer. | 12-08-2011 |
20110076109 | Blind Fasteners and Methods of Manufacture - Blind fasteners and methods of manufacture. The blind fasteners each have a sleeve with a sleeve head thereon and a stem having a stem head thereon. The stem extends through the sleeve from an end of the sleeve opposite the sleeve head with the stem head adjacent the end of the sleeve opposite the sleeve head. The sleeve has a non-uniform wall thickness to cause the sleeve to buckle outward against a blind side surface of a work piece to form a blind side head when the stem is pulled relative to the sleeve head to set the fastener in a work piece, the work piece having a thickness which may range from a predetermined minimum grip to a predetermined maximum grip. Various embodiments are disclosed. | 03-31-2011 |
