Publication number: 20200086593Abstract: Complex laminated composites may be repaired by removal of individual damaged plies through peeling in order to exploit the weaker interlaminar properties of these composites. Upon removal of the individual damaged plies through peeling, replacement plies may be added to restore the laminated composite. In addition, when damage extends through the thickness of a laminated composite, a plug may be used to allow plies to be replaced while maintaining contour within the repair region. A caul plate also may be used to stiffen and maintain the contour of a repair region while peeling and removing plies from the repair region.Type: ApplicationFiled: November 25, 2019Publication date: March 19, 2020Inventors: Denver R. Whitworth, Eric W. Nottorf, Vance N. Cribb, Dumitru Jitariu

IMPROVED APPARATUS FOR SEALING AND INFLATION OF DAMAGED INFLATABLE ARTICLES, SUCH AS PUNCTURED TIRES
Publication number: 20200086595Abstract: An apparatus for repairing and/or inflating a damaged and/or deflated inflatable article, such as a punctured and/or flat tire, includes a container for receiving and retaining for dispensing, a sealant composition and a compressor assembly which is releasably connectable to the container. The container has associated therewith a valve assembly which allows for controlled dispensing of the sealant composition from the container to the damaged and/or deflated inflatable article. The container is progressively and selectively movable between respective first and second positions/configurations. In the first position/configuration, the container is disposed substantially parallel to the compressor assembly and in the second position/configuration the container is disposed at substantially right angles to the compressor assembly. The first and second positions/configurations correspond to storage and dispensing positions respectively for the sealant composition from the container.Type: ApplicationFiled: February 15, 2017Publication date: March 19, 2020Inventor: Terence Dowel -
Publication number: 20200086596Abstract: A method of installing a slide fastener assembly in a thin shell garment includes: providing a slide fastener chain comprised of two interlocked rows of teeth, each row of teeth being attached to a cord bundle of a respective slide fastener tape; removing the interlocked rows of teeth from a portion of the slide fastener chain, thereby defining a length of the slide fastener chain without teeth; introducing a reinforcing film to the cord bundles, at a location along the length of the slide fastener chain without teeth, to shape the cord bundles for accommodation of a pin and box assembly; cutting the slide fastener chain at a film-reinforced location along the length of the slide fastener chain without teeth, thereby defining a semi-finished slide fastener assembly terminating in a film-reinforced end; and attaching the semi-finished slide fastener assembly to one or more panels of a thin shell garment.Type: ApplicationFiled: November 25, 2019Publication date: March 19, 2020Inventors: Gary DAVIS, William Garland MAYO
