20130175730 | SEALANT MOLD FIXTURE FOR A DOME ELEMENT - A sealant mold for sealing a dome element particularly at a lower region about an interface with a substrate such as an aircraft fuel tank wall. The sealant mold is formed from a lightweight plastic material, and includes an outer cap portion having an opening formed therein, in combination with an integral outer skirt to define a gap or trough for receiving and supporting a metered quantity of a curable sealant material. The mold is slidably fitted onto a dome element with outer skirt displaced downwardly to extrude the sealant material about the lower region of the dome element. The sealant material is allowed to cure, after which the sealant mold can be stripped from the cured sealant material. | 07-11-2013 |
20120219380 | INSULATED AND SEALED CAP FOR A FASTENER COMPONENT - An insulated, sealed cap overlies and protects a fastener component or the like on a substrate in association with a substrate opening. The sealed cap includes an outer cap component filled partially with a selected sealant material and assembled with an inner collet sized and shaped to fit with a slip fit about the fastener component such as a nut or the like at one side of a selected substrate, such as the skin of an aircraft. An inboard edge of the inner collet seats on and substantially seals with the substrate. The outer cap component is then displaced toward the substrate to extrude the sealant material into a thin and substantially uniform layer joined with an extruded outer bead on the substrate, and then permitted to cure. Tapered ribs on the inner collet effectively lock with the outer cap component during sealant material curing and subsequently. | 08-30-2012 |
20120217673 | SEALANT MOLD FIXTURE FOR A DOMED CAP - A sealant mold for sealing a domed nutplate unit particularly at a lower region about an adhesively attached interface with a substrate such as an aircraft fuel tank wall. The sealant mold is formed from a lightweight plastic material, and includes an inner cap in combination with an outer skirt to define a gap or trough for receiving and supporting a metered quantity of a curable sealant material. The mold is fitted onto a dome of the nutplate unit with an inner cap inboard edge landed onto a dome shoulder. The outer skirt is then displaced downwardly about the landed inner cap to extrude the sealant material about the lower region of the nutplate unit particularly such as the adhesively attached interface with the substrate. The sealant material is allowed to cure, after which the sealant mold can be stripped quickly and easily from the cured sealant material. | 08-30-2012 |
20100314511 | LOW PROFILE ADHESIVE MOUNTED FIXTURE BUTTON - A low profile fixture button is provided for adhesive attachment to a substrate in a temporary or substantially permanent manner. The fixture button includes a plurality of preferably four over-center spokes substantially in a common plane and carrying a mounting plate having a pressure sensitive adhesive material thereon. The spokes are carried by an outer backstop rim, and are initially oriented with the mounting plate advanced toward the substrate. In a preferred form, the backstop rim seats within a counterbore formed in the rear side of a larger attachment adapted for low profile mounting onto the substrate. Pressing of the fixture button toward the substrate engages the advanced mounting plate with adhesive thereon with the substrate, and forces the spokes to displace over-center to a retracted position withdrawn substantially into the backstop rim and any associated larger attachment for low profile mounting onto the substrate. | 12-16-2010 |
20100147453 | PEEL PLY MASKING DEVICE FOR AN ADHESIVE BONDED ATTACHMENT - A peel ply conformable masking device for protectively overlying a pre-cleaned bonding surface of an adhesive attachment adapted for bonded affixation to a selected substrate, such as an adhesive attachment of the type disclosed in U.S. Pat. Nos. 5,013,391 and 6,773,780 having a bonding surface circumscribing a temporary attachment member for holding the attachment against the substrate for the duration of a bonding agent cure time. The bonding surface of the adhesive attachment is pre-cleaned as by sand blasting and/or etching, and the masking device comprising a peel-off film carrying a thin layer of a peel-off adhesive is placed thereover to prevent contamination thereof. The masking device includes at least one aperture surrounding the temporary attachment member, and further includes at least one outwardly protruding and easily grasped pull tab for facilitated peel-off separation from bonding surface immediately prior to bonded affixation to the selected substrate. | 06-17-2010 |
