Abstract: 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plate with adhesive thereon with the substrate, and forces the spokes to displace over-center to a retracted position withdrawn substantially into the backstop rim and any associated larger attachment for low profile mounting onto the substrate.

Abstract: 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.

Abstract: A standoff attachment for bonded fixation to a substrate includes a standoff post with internal nut for engaging a mating fastener used to mount a support element such as a line clamp substantially at a distal end thereof. The standoff post extends from an enlarged bond-on base and defines a hollow slotted channel of noncircular cross-section which terminates at the distal end in an in-turned flange defining an open fastener-receiving port. The nut includes a keyed rib sized and shaped for axial slide-fit reception into the slotted channel at an inboard side of the distal end flange, wherein this rib mates with the slotted channel shape to preclude substantial nut rotation. An elongated slotted plug is secured within the slotted channel to retain the nut, preferably with a minor degree of axial freedom, axially between the plug and the distal end flange.

Abstract: An adhesive bonded attachment assembly is provided for supporting and retaining an insulation blanket on a substrate such as aircraft engine nacelle or the like. The attachment assembly includes a stud attachment having a base for adhesive bonded affixation to the nacelle substrate and a fastener element such as a threaded stud extending from the base at least partially into a grommet-lined mounting port formed in the insulation blanket. A radially enlarged, insulated cap fastener is secured to the fastener element to retain the insulation blanket on the nacelle substrate in a manner shielding surrounding structures and components from heat generated during engine operation. The insulated cap fastener projects radially beyond the associated grommet for improved heat-shielding of the adhesive bonded stud attachment, thereby safeguarding against debonding of the attachment base in response to high temperature exposure.

Abstract: An adhesive attachment is provided for securely mounting an attachment component such as a threaded stud or the like on the surface of a selected substrate, wherein the adhesive attachment provides an electrically conductive ground path for grounding the attachment component and/or a selected structure mounted thereto to the substrate. In one preferred form, the attachment component is a threaded element such as a stud or nut. Upon mounting of the attachment component on the substrate and subsequent connection of the threaded element to a mating threaded member, e.g., of the selected structure to be mounted onto the attachment component, a conductive ground pin is pressed into electrical contact with the substrate for grounding the attachment component and/or the selected structure mounted thereto.

Abstract: An adjustable mounting bracket for secure adhesive mounting onto an exposed edge of a substrate, wherein the mounting bracket is adapted for subsequently supporting a selected structure such as tubing, wire bundles, etc., relative to the substrate. The mounting bracket includes slidably interfitting, generally L-shaped bracket members which cooperatively define a slidably overlying pair of mounting plates and an associated pair of slidably separable clamp jaw plates having inboard faces carrying a selected bonding agent and adapted to seat firmly against opposed substrate edge surfaces. A resilient fixture pin is carried by the mounting plates and can be actuated to apply a positive force urging the clamp jaw plates against the opposed surfaces of the substrate edge of the duration of a bonding agent cure time, after which the fixture pin can be forcibly removed from the mounting bracket.

Abstract: A bond strength tester unit is provided for testing adhesive bond strength of a nutplate or the like attached to a substrate, such as by adhesive bonded attachment to a blind side of the substrate in substantial alignment with a substrate opening. The nutplate may be constructed according to U.S. Pat. No. 5,013,391, and carries a fastener element such as a threaded nut or the like for subsequent connection with a mating fastener element such as a threaded bolt or the like passed through the substrate opening. The tester unit includes a tool tip having a reaction head for engaging the substrate, in combination with an actuator pin for applying a test force of selected magnitude against the adhesively bonded nutplate. In the event of inadequate bond strength, the actuator pin will separate the nutplate from the substrate.

Abstract: A sleeve cutter is provided for precision cutting of a length of metal tubing or the like. The sleeve cutter includes a mandrel or spindle for supporting a tube-shaped sleeve thereon between a pair of rotary-driven cutting wheels adapted for movement together between retracted positions spaced outwardly from the mandrel, and advanced position with cutting edges in engagement with the mandrel-supported sleeve. Each cutting wheel further includes a shaping step or land for removing any burr or flare from the cut sleeve end.

Abstract: An installation tool for use with a liner sleeve attachment, such as a nutplate assembly for mounting onto a substrate blind side as disclosed in U.S. Pat. No. 5,704,747. The installation tool includes retractable grip jaws for gripping and pulling a fixture pin protruding from the attachment, for initially advancing a tapered tool nose piece into deforming engagement with an attachment liner sleeve leading end to flare and/or expand the liner sleeve to lock the liner sleeve onto the substrate. Continued pulling action exerts a sufficient force to collapse a fixture pin head and thereby permit pull-removal of the fixture pin from the attachment. The nose piece is carried by a retractable inner housing normally retained in an advanced position for deforming the liner sleeve, and thereafter movable to a retracted position spaced from the liner sleeve to accommodate substantially unobstructed fixture pin separation from the attachment.

Abstract: An adsorbent material, and method for making same, is disclosed wherein an application is made on the adsorbent material of a polymer coating with surface porosity. The product adsorbent material retains it adsorptive properties, while the coating provides advantages such as reduced dusting. For particulate or pellet forms of adsorbents, a reduction in attrited dust is useful for improved performance in emission control systems. The coating may also be used to color the product.

Abstract: The present invention relates to a process for treating wood and other cellulosic materials to render the resistance to wood attacking organisms, such as termite, fungi and insects. More particularly, the present invention relates to a process for treating wood with borate preservative formulation which contains at least one boron-containing component and at least one resinous component capable of retaining impregnated borate inside the treated wood even upon contact with water. The resinous component may be rosin, rosin derivative, tall oil-based compound, or mixtures thereof.
