Abstract: 2 of 15 ABSTRACT A braid wrapping wheel or carrier is mounted for rotation about its axis and concentrically surrounds a mandrel. The carrier bears rotatable spools of filament or fibre material about its periphery. One end of each filament is affixed to the mandrel at a point axially displaced from the plane of carrier rotation and the filaments braid about the mandrel during carrier rotation and axial shifting of the mandrel along its axis. A guide ring assembly contacting the filaments intermediate of the spools and the filament contact area on the mandrel define a path of movement for the inclined filaments. A fixedly mounted annular guide ring assembly formed of two concentric annular rings, concentric about the mandrel partially defines a closed plenum chamber bearing a liquid resin under pressure. The resin is fed through a thin slit created by the space separating the two concentric rings over which the filaments are trained to resin impregnate the filaments. By control of the pressure of the liquid a bead of liquid is maintained at the slit for wiping by the filament during passage with the pressure being sufficient to cause the resin to bleed from the plenum chamber via the slit during filament training about the guide ring in a suitable quantity as to fully resin impregnate the filaments.

One set of tubes are straight and are substantially in contact with the bends of the serpentine tubes so they close the lowermost chamber and the gas passages on one side.  The gas passages are closed on the serpentine tube side by a removable closing plate.  One set of tubes joining the upper left side of the upper manifold to the lower left side of the lower manifold, and the other set of tubes joining the upper right side of the upper manifold to the lower right of the lower manifold.  The openings from passage to passage are offset so to require a gas flowing through said passages to traverse one passage from front to back and the next passage from back to front.  Means are provided for introducing liquid into the lower manifold and for withdrawing the liquid from the upper manifold, and means for introducing a combustion gas into the lowermost of the superimposed passages. The combustion gases rise successively through the passages which it successively and alternatingly traverses from front to back and then from back to front until it exits from the uppermost chamber through the gas outlet in the top, liquid flowing through the manifolds and tubes being heated by the combustion gas.
