Abstract: A process to use an unsaturated polyester resin system comprising preparing a curable cumene-quat curing system. The cumene-quat curing system can comprise an unsaturated polyester resin, a peroxide initiator, a quaternary ammonium salt component, a 2,4-pentanedione component, and an inhibitor component. The peroxide initiator can comprise a cumene hydroperoxide component. The process can further comprise applying the curable cumene-quat curing system in a cured-in-place pipe rehabilitation process.

Abstract: A resin composition including a modified acrylic unsaturated polyester resin composition comprising a maleic dicyclopentadienyl glycol polyester which is dissolved in a mixture of styrene monomer and methylmethacrylate monomer. The maleic dicyclopentadienyl glycol polyester is the reaction product of a glycol or mixture of glycols, an ethylenically unsaturated polycarboxylic acid moiety and dicyclopentadiene. The glycol utilized as a reactant preferably has a structure defined by: H--(OCHR--CH.sub.2).sub.n --OH wherein R is H or CH.sub.3 and n is 1-10. The concentration of unsaturated polyester is preferably about 40 weight percent to about 75 weight percent in the resin composition. The concentration of styrene monomer ranges from about 5 weight percent to about 40 weight percent, while the concentration of methylmethacrylate monomer ranges from about 5 weight percent to about 45 weight percent.

Abstract: The present invention employs an arrangement of multiple containers for marinating food. The container arrangement includes an inner container having a bottom wall and side walls which define a food holding chamber. A plurality of apertures are provided in the bottom wall of the inner container for marinade to passage. The inner container further has a noncircular cross sectional configuration defining a plurality of bottom corners. An outer container similarly has a bottom wall and side walls defining a marinade holding chamber for holding a given level of marinade. The outer container is configured in to accept the inner container. Alternatively, the side walls support the inner container in an elevated position on rotation thereof relative to the outer containers.

Abstract: The present invention provides a dunnage rack including a molded pallet having a plurality of legs with caster supports integrally secured thereto, and to a method of forming such a dunnage rack. The dunnage rack is formed by first providing a mold for the pallet. A lower end of each leg portion of the mold is then blanked off with a caster support. The caster supports include a base plate arranged to support a caster and a plurality of flanges which extend upwardly from the edge, of the base plate into the mold. The flanges have an irregular surface. In a preferred embodiment, the irregular surface is formed by a plurality of openings or apertures. A molding material introduced into the mold engages the flange irregular surface to secure the caster support to the pallet legs.

Abstract: The present invention is a shelving system having height adjustable shelves. The shelving system includes a plurality of elongated support posts having recesses spaced along the longitudinal axis. At least one resilient support post clip is attached to each support post within a recess to provide a shelf support. A shelf member having recesses at least partially accepting the post clip, is positioned in detachable nesting relationship with the support clips.The shelf member further includes an upper surface having alternating transverse ribs and recesses, and a lower surface having alternating longitudinal ribs and recesses. The ribs serve to reinforce the shelf member both longitudinally and transversely.Each shelf member further comprises an outward projecting support rail extending along one or more edges of each shelf member. A connecting mechanism simultaneously engages the support rails of adjacent shelf members and retains the adjacent shelf members in fixed relation with each other.

Abstract: Epoxide-vinyl ester resins having significant amounts of epoxide and ethylenically unsaturated groups may be thickened by reaction thereof with polyfunctional amines. The resulting resinous products, when molded at elevated temperatures, exhibit increased viscosity and controlled flow.
