Abstract: A pultrusion machine for forming a laminated composite with a predetermined profile and the product obtained. The apparatus comprises at least two spools for supplying elongated reinforcements. A collator receives the elongated reinforcements and arranges the reinforcements in layered relationship to form a layered elongated bundle. A supply member wets the layered elongated bundle with plastisol to form a wetted elongated bundle. The wetted elongated bundle is transported through a pultrusion die wherein the wetted layered bundle is molded into the predetermined profile. A converting apparatus cures, or converts, the wetted layered bundle into the layered composite. A particularly preferred embodiment is an extrusion comprising a reinforcing material wherein said reinforcing material comprises a fiber reinforced plastisol.

Abstract: Disclosed is a pultrusion machine for forming a laminated composite with a predetermined profile and the product obtained. The apparatus comprises at least two spools for supplying elongated reinforcements. A collator receives the elongated reinforcements and arranges the reinforcements in layered relationship to form a layered elongated bundle. A supply member wets the layered elongated bundle with plastisol to form a wetted elongated bundle. The wetted elengated bundle is transported through a pultrusion die wherein the wetted layered bundle is molded into the predetermined profile. A converting apparatus cures, or converts, the wetted layered bundle into the layered composite. A particularly preferred embodiment is an extrusion comprising a reinforcing material wherein said reinforcing material comprises a fiber reinforced plastisol.

Abstract: A method of manufacturing a sheathed electrical heater assembly comprising the steps of: molding a core element into a desired shape, the core element having an outer surface; heating the core element at an elevated temperature sufficient to release organic material from the core element; placing a heating element in communication with the core element; and, encapsulating the core, and the heating element in an insulation protection layer, whereby the heater assembly is formed. Additionally shown is a sheathed electrical heater assembly comprising: a core made of an organo-ceramic material; a heating element in communication with the core; an insulation protection layer encapsulating the core and heating element to produce the heater assembly, the protection layer comprising and organo-ceramic material; and, a sheath encapsulating the heater assembly, the sheath also comprising an organo-ceramic material.

Abstract: The antenna disclosed is formed of fiber reinforced resin material, having reinforcing fibers in the form of strands of electrically conductive graphite, the strands being embedded under tension in the shaft of the antenna to provide high stiffness, and the graphite strands being electrically connected with a metal antenna lead-in terminal at the base end of the antenna shaft.
