A coating composition suitable for forming an adhesive primer layer on a hydrophobic polyester resin support, wherein said coating composition essentially consists of (an) addition polymerizable monomer or mixture of such monomers having dissolved therein at least one of the polymers (i) and/or (ii), wherein : i) is a linear copolyester of isophthalic acid and at least one other dibasic carboxyl...

A new tire construction and method which makes the toe guard integral with the inner liner is provided. A tire is made using an inner liner that has a width substantially equal to the width of a prior art inner liner plus the width of prior art toe guards minus any overlap. The edges (14) of the inner liner (12), which wrap around the bead, are reinforced so that the edges of the inner liner prote...

An arc plasma torch having a tapered-bore electrode provides a long, columnar plasma arc. The torch includes a torch housing, a tapered-bore electrode, a gas-constricting nozzle, and a swirling gas flow generator. The electrode is mounted within the housing and has a closed inner end and an open outer mouth. The electrode has a longitudinally extending, tapered bore. The bore has its largest dimen...
