A method of constructing a fiberglass structure features that enable a gelcoat protective layer to be applied to an article formed in an automatic process. In the process, a web of fiberglass is drawn through a bath of structural resin to impregnate the fiberglass with the structural resin. A web of organic, porous veil material is drawn through a bath of gelcoat resin simultaneously with the structural resin impregnated web of fiberglass. The two webs are squeezed together, and the resin metere...

An improved filing cabinet is provided which lends itself particularly to a double-walled fiberglass construction. The filing cabinet of the invention includes a molded fiberglass base which defines a rectangular frame normally disposed in a vertical plane. One or more file drawers are supported within the frame above one another, the support of each drawer being effectuated by elongated strips mounted on the ends thereof. The strips are supported in depressions formed in the inner wall of the f...

An antenna which is constructed exclusively of fiberglass, with the sole exception of the electrical conductors, couplings, and upper and lower ends, which may incorporate fiberglass or some other material, which antenna is constructed in a series of lengths, or in a single length in the case of a very short antenna, each of the lengths being essentially of hollow tubular construction, with the walls of the tube made up of alternate layers of glass fiber filaments, one such layer being made up o...

A shoe for sanding and rubbing tools is made of laminations of fibre glass of predetermined thickness to provide the right amount of stiffness, flexibility and 100 percent memory. For orbital machines, a vinyl rubbing surface is bonded to the circular shoe with a peripheral edge part forming a tire bonded to the edge of the shoe.

A molded resin-bonded fiberglass processing tank having a hub structure formed integrally with the end wall. The hub structure is made up of a laminated core overlayed with a fiberglass laminate. A gudgeon is attached to the core. Reinforcing ribs are laid on the end wall, the ribs, which radiate from the hub, extend over the contiguous portions of the cylindrical wall of the tank. The ribs are formed with a center core, preferably of foamed plastic. A belt track and a support ring are also form...

A tapering tool having an expandable collet over which the end of a fiberglass pipe is received incorporates a mechanism to lock an expandable collet in a fixed position to prevent same from expanding outwardly and becoming tightly wedged against the interior of the pipe during the cutting cycle. The tapering tool further includes a radially-fed cutter blade arrangement which progressively draws the cutter blade onto the pipe being tapered during the cutting operation.

The present invention provides a narrow orthopedic casting tape which can be handled in longer lengths suitable for economical production of coated fabric products. The narrow casting tape of the present invention is knitted as a wide fiberglass fabric with at least one removable connecting yarn in the length (i.e., warp) direction of the fabric which acts to connect two narrower strips of fiberglass fabric. The removable connecting yarn is subsequently removed from the fabric by a heat treatmen...

A fiberglass insulated conductor referenced by numeral (100) is provided for which at least one fiberglass layer (6') in close proximity to the electrical conductor (2) has been treated with a solution operative upon heat aging to render the treated fibers sufficiently frangible to break and eliminate stringing during the process of stripping the fiberglass from conductor (2). Another embodiment referenced by numeral (300) illustrates that one or both an electrically insulative tape or extruded ...

A fiberglass bulkhead door assembly includes a bulkhead enclosure for mounting on a bulkhead, at least one door and top and bottom hinges for mounting the door to the bulkhead enclosure. The bulkhead enclosure includes fiberglass side walls, a sloping fiberglass top wall and a tie bar connected between the side walls. The top wall has a door opening. The door is movable between a closed position covering the door opening and a open position providing access to the bulkhead. Each of the hinges in...

A liquid cooling tower is formed from fiberglass reinforced polyester resin panels, a fiberglass reinforced polyester resin liquid basin, and a fiberglass reinforced polyester resin top assembly which includes a fan and a water distribution pipe. One or more cross beams extend between two opposed side panels for supporting a porous heat and mass transfer section. The panels are formed so that the weight of the tower and the fill material is distributed to, and supported by, the corners and inlet...
