    摘要： A laminated game racket frame having a closed hoop-shaped inner frame and an outer frame with the outer part of the inner frame integrally bonded to the inner part of the outer frame to form a unitized body, each frame being formed as a laminate comprised of a plurality of strips. Some of these strips are made of wood, thermoplastic resin or metal, and some are made as laminates themselves from plies of reinforced thermosetting resins.

    摘要： Microcapsules having an average diameter below 5 microns and containing a flame retardant material are incorporated into polymeric materials, such as polyurethane foams without affecting the structural integrity of the cell walls of the foam. The capsules are chemically bonded to the foam, as well as physically incorporated therein by employing polyhydroxy polymer-containing capsule wall materials which react with the isocyanate used in the polyurethane. The minute capsules are incorporated into paint to give increased hiding power as well as flame resistance, and are co-extruded into filaments.

    摘要： A substantially colorless dilactone chromogenic material having the structural formula ##SPC1##And ##SPC2##WhereinR represents an alkyl group, an aryl group, an aralkyl group, an acyl group or an aroyl group; andX represents a hydrogen atom, a halogen atom, an alkyl group or a nitro group.The dilactone compounds are produced from precursor compounds that are formed by reacting pyromellitic dianhydride with a resorcinol having at least the fourth or the sixth position unsubstituted, in the presence of a dehydrating agent to form xanthyl derivatives of isophthalic and terephthalic acid. These precursors are then further reacted to form the dilactones. The dilactones are used in pressure-sensitive copy systems comprising a support bearing microcapsules containing the dilactones, alone, or in combination with other chromogenic materials.
