A thermosetting-resin-based coating that is capable of forming a substantially flame-resistant barrier upon being exposed to heat. The coating includes a thermoset resin, an acid catalyst having a pKa value of less than 2, a filler selected from glass, mica, talc, perlite, vermiculite and combinations thereof, and an organic-intumescent material. The thermoset coating is at least 75% of the total weight of the coating.

Flame-resistant-thermoset coating

A co-injection nozzle pin () having downstream and upstream ends. The nozzle pin has therein a central bore () including an upstream end () adapted to communicate with a first material and a downstream end () exiting at the downstream end of the pin. The nozzle pin also has an outer surface () including a first portion () having a diameter D, a second portion () having a diameter D, wherein Dis less than Dand the first portion is rearward of the second portion. The pin further includes a channel () spiralling around the outer surface and being adapted to communicate with a second material. The channel () includes a first segment () defined in the first portion () of the outer surface and increasing in depth as it travels in a downstream direction and a second segment () defined in the second portion () of the outer surface and decreasing in depth as it travels in a downstream direction.

Co-injection apparatus for injection molding

A method of extruding a homogeneous plastic rod substantially free of shrink voids, the method having the steps of: extruding a rod central portion of plastic material having a glass transition point and a Vicat softening point below the glass transition point, the rod central portion having a center core and an outer skin; cooling the rod central portion while maintaining the outer skin above the Vicat softening point until the center core is cooled to approximately the Vicat softening point; using an extruder to extrude around the rod central portion a sheath of the same plastic material, the sheath having an outer skin and inner and outer portions, such that the rod central portion acts as a heat sink for the inner portion of the sheath, and such that, at the extruder, the plastic material forming the outer skin of the rod central portion is melted upon contact with the plastic material forming the sheath and the plastic material of the rod central portion and the plastic material of the sheath form the homogeneous rod, and such that the plastic material forming the center core of the rod central portion remains at a temperature below the glass transition point; and cooling the sheath while maintaining the outer skin of the sheath above said Vicat softening point until the inner portion is cooled to approximately the Vicat softening point.

Injection molding apparatus comprising a platen, a die which is fixed to the platen and which defines a mold cavity having an inlet, a co-injection manifold mounted on the platen, the manifold including a nozzle housing having forward and rearward ends, the nozzle housing including an outlet which is located adjacent the forward end and which communicates with the mold cavity inlet, first and second spaced apart inlets which are located adjacent the rearward end and which are respectively adapted to communicate with first and second injection nozzles, a first passageway communicating between the first inlet and the outlet, and a second passageway communicating between the second inlet and the outlet.

Co-injection manifold for injection molding

A method of manufacturing an etched extrusion, the method comprising the steps of extruding a thermoplastic material to produce a hot extrusion, and contacting the extrusion, while the extrusion is still hot, with a mixture of at least two fluids having different thermal conductivities so that the extrusion develops an uneven outer surface due to different rates of shrinkage caused by the different thermal conductivities.

A co-extruded welting for fixing a seat cover to a vehicle seat frame, the welting comprising an elongated, single-piece strip including a web having opposite ends and a pair of edges extending between the opposite ends, and the strip also including a sheath extending along one of the edges between the opposite ends, the wed and the sheath being made of a first plastic material, and a core surrounded by the sheath and made of a second plastic material which is different from the first plastic material.

Seat welting

A rain gutter assembly including an elongated rain gutter including an end and a channel extending longitudinally of the rain gutter, and a connecting member engaged with the end of the rain gutter and including a bayonet portion received in the channel. The rain gutter arranged with a grommet along a rear wall thereof and a mounting fastener engaged within the grommet so as to attach the rain gutter to a building wall. The rain gutter assembly including a downspout having a grommet secured to a rear wall thereof for supporting the downspout to the building wall.. With a mounting fastener slidingly engaging the grommet so as to attach the downspout to the building wall.

Hinged rain gutter

A rain gutter assembly including an elongated trough-like rain gutter having a rear wall, a trough and a leaf guard integrally connected by a pair of living hinges, grommets adapted to house a fastener for supporting the rain gutter, and a connector for sealingly connecting a pair of closely-spaced, aligned rain gutters.

An office space dividing partition having an electrical raceway. The raceway includes an extruded plastic spine having a vertical web; a top portion which includes an extruded mounting slot; a bottom portion which includes first and second extruded grooves and a noise seal; and, an intermediate portion which defines four passageways for communication and power wiring. First and second extruded plastic side panels are telescoped into engagement with the first and second extruded grooves of the spine. An extruded panel-to-raceway connector connects the spine to the bottom edge of an office space dividing panel. Raceway stabilizers extend outwardly from the spine to engage support posts which support the panels. Raceway shrouds, which conceal the posts adjacent to the ends of the raceways, are positionally keyed to the spine for accurate mating with the side panels of the raceway.
