An air removal and fastener extraction system for use in retreading tires is disclosed. The system includes a strap that is disposed over a splice region of the tread during precure retreading. A plurality of fasteners are inserted through the strap and across the splice. This securely holds the splice region intact, allows air to be vented during curing, and permits removal of all fasteners in a single pulling motion exerted on the strap after the curing process is completed.

Air removal and fastener extraction system

A method and adhesive system for bonding at least two elastomeric substrates together. The method comprises subjecting the substrates to a priming treatment followed by applying to the primed substrates a heat-curable polyurethane adhesive composition comprising an isocyanate-terminated prepolymer and a polyhydroxide compound. The surfaces of the substrates so treated are contacted and subjected to heat-curing to bond the substrates together.

Tire bonding systems

Method for forming a composite elastomer tire tread by applying a heat curable liquid elastomer mixture to a thin rubber sheet and curing the liquid mixture to form the composite tire tread. A tire retreaded with such a composite tire elastomer tread is also described.

Method of fabrication of composite tire thread

Disclosed is an erasure-prevention clip for use with an information disk or diskette assembly of the type comprising a jacket or envelope containing a magnetic diskette. Conventionally, the jacket, which is typically square, has in one edge thereof a notch which is covered by some removable tab to prevent erasure of recorded data; e.g., tape or the like, which, after removal, leaves the notch exposed and therefore subjects the diskette to possible erasure of the material previously recorded thereon. The present invention provides a notch-closing clip in the form of a U-shaped member having a bight dimensioned to fit the notch and a pair of legs closely spaced apart to receive the jacket and dimensioned to overlie relatively broad areas of opposite faces of the jacket that border the notch. The legs converge away from the bight so as to increase their grip on the jacket. The clip is of opaque material and is designed primarily for soft or so-called floppy disks of the five-inch size and having the notch in that edge that is parallel to the line of movement of the jacket into and out of the disk drive.
