Abstract: A system for placing chopped fiberglass strands onto a preform screen where desired includes a relatively light-weight chopper/feeder unit mounted on the outer end of a robot arm in closely spaced relation to the preform screen for robotically directing the chopped fiberglass strands onto the preform screen where desired with very little loss. Within the chopper/feeder unit is a cutter for chopping the fiberglass strands to the desired length. The cutter is driven by a variable speed motor attached to the chopper/feeder unit. Also attached to opposite sides of the chopper/feeder unit are a pair of air amplifiers that produce a sufficient volume and velocity of air flow around said cutter and through said unit to carry the chopped fiberglass strands away from the cutter and out through a discharge chute onto the preform screen.

Abstract: This application discloses a process of making electrically conductive fiber glass articles whereby carbon black is mixed with the resin to provide the desired value of electrical conductivity. A large amount of titanium dioxide is added to counteract the black color resulting from the carbon black addition. The resulting paste is added to fiber glass and the resin is cured thus resulting in a light gray or other gray tones. It is important that the carbon black, titanium and resin be thoroughly mixed to disperse the carbon and other pigments, and the mixing may be accomplished by means of a high intensity mixer or ball mill.

Abstract: A tray is disclosed especially suitable for use in the candy industry. The tray has a unique arrangement of legs, lugs, and anti-slip features which facilitate stacking, handling, and cleaning of the trays.

Abstract: A simulated cedar shake panel for walls or roofs having at least two courses of simulated shakes in relief therein, the shakes being in overlapped and underlapped relation with a varied butt line, and recessed underlaps between side-by-side shakes. Part of each underlap is recessed enough to contact the roof or wall surface and provide a multiplicity of support surfaces for the panel. A step provided in each underlap near the bottom thereof forms part of the shake simulation and also adds to the structural rigidity of the panel.Tongue and groove side-to-side and top-to-bottom panel interlocks form part of the shake array simulation, so that the interlock structure is concealed and the desired non-uniform shake appearance enhanced.A stackable corner member one shake high is provided, the corner member having a skirt element which interfits with the butt edges of overlapped panel shakes to take up gaps due to the random butt line.An angled cap member is provided to finish off hips and ridges.
