Abstract: A microencapsulated adhesive and a method for producing that microencapsulated adhesive is disclosed. The adhesive is produced from an alkyl acrylate or methacrylate monomer having about 4 to about 12 carbon atoms, or a mixture thereof. The monomer is encapsulated by interfacial polymerization, gelatin/gum arabic coacervation or melamine/formaldehyde encapsulation. The microcapsules may be polyamide or polyurea. The monomer is polymerized in the microcapsules by heating to form an adhesive that is non-tacky, but becomes tacky upon application of external forces, such as shearing. The microencapsulated adhesive composition may be used, among other applications, as an adhesive for stamps or envelopes.

Abstract: A break-away lug nut positioner for holding lug nuts on a race car wheel to facilitate more rapid tire changes during pit stops. The break-away lug nut positioner includes a spacer that supports a lug nut at a proper distance over a mounting hole of a race car wheel. That is, the spacer holds the lug nut so that it is adjacent to a threaded mounting stud when the wheel is held flush against the race car hub. During installation, the lug nut is driven into the spacer cavity, forcing the spacer to break into pieces. The adhesive bond between the lug nut and the spacer is weaker than the individual pieces of the spacer, which causes the spacer to separate cleanly from the lug nut, allowing the lug nut to seat properly against the wheel mounting plate. That is, the adhesive and the material and configuration of the spacer are selected so that the spacer breaks cleanly away from the lug nut, and no spacer material remains between the lug nut and the mounting plate.

Abstract: A self-sealing furring nail has a nail and a furring wad assembly. The furring wad assembly includes a plunger friction fit on the nail and a housing friction fit on a shaft of the plunger at one end of the housing, and at the other end of the housing there is a gap between the housing and the nail. The activating surface of the plunger is located within the housing, and the plunger's shaft extends from within the housing outside of the housing towards the nail head. The housing has a package of sealant material inside. The package has a sealant encased within a burstable bag. When the furring nail is driven through building paper into a frame of a building, the head of the nail contacts the plunger's shaft causing the plunger's activating surface to compress the bag of sealant. The bag bursts and the sealant passes through the gap between the nail and housing and seals the penetration hole between the nail and the building paper.

Abstract: A chemical anchor bolt and cap assembly installable in a hole drilled in masonry for fastening an object thereto The threaded shank of the bolt and the hollow cap extending from its end are inserted into the hole, causing an uncured bonding agent deposited in the hole, such as an epoxy, to surround the cap and the shank. When the epoxy hardens the cap is then embedded in the epoxy to create a void below the end of the shank. Cast in the epoxy surrounding the shank is a female thread that complements the shank thread. To permit the bolt to turn and cause the end of the shank to advance into the void and thereby tighten the fastening, the threaded shank has coated thereon a releasable barrier layer that acts to masks surface irregularities in the shank thread and to slightly space the shank thread from the female thread. As a consequence, the female thread cast in the epoxy is functionally free of irregularities and is loosely intermeshed with the shank thread whereby the bolt can then be easily turned.
