Abstract: Method and apparatus for controlling the stacking height of stackable products during compression molding off stops includes slides that are movable into and out of an end of blind pockets in a compression mold in which the stack height surfaces are formed during the molding cycle. The slides are held in a retracted position until after the mold is closed and the molding compound flows to the shape of the molding cavity inside the mold including the blind pockets. Then the slides are extended into the ends of the respective blind pockets the same distance to compress the molding compound and obtain the desired height of the stack height surfaces formed by the blind pockets.

Abstract: A preformed pallet is provided having first and second outer layers that sandwich a cellular or honeycomb shaped core. The peripheral edge of the preformed pallet may be inserted into the molding device having one or more heating elements, which function to focus heat onto the peripheral edge. Once heated, the peripheral edge of the preformed pallet may be reshaped by one or more die sets forming the peripheral edge into an enclosed pallet.

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: A tray suitable for use in mass raising insect larva, particularly flys (flies), in and artificial environment from incubation through hatching and growth and including a smooth bottom and four upwardly extending sides being open about fifty percent (50%) of the total height to provide sufficient ventilation to maintain a predetermined temperature to satisfy the developing process. The trays are stackable and have ribs at their corners to provide structural strength.

Abstract: An apparatus is disclosed for use in the exercise of the human body, which comprises a fiberglass pultruded shape of a predetermined oblong geometry with an elastic sheath formed about the exterior thereof over the length of the fiberglass pultruded shape. The fiberglass pultruded shape has fiberglass filaments dimensionally stabilized in a hardened resin system. Material properties of the filaments in the resin system are selected such that the ultimate elongation design value of the filaments and the resin system is greater than the actual maximum elongation of the filaments and the resin system when the fiberglass member is flexed in the exercise process. Also, the resin is selected for toughness sufficient to provide a useful flexural fatigue life.

Abstract: The invention relates to a method of manufacturing a sign or similar article by providing a fiber reinforced plastic laminate structure having pre-selected dissimilar laminate layers. After sandblasting, the dissimilar materials that have been exposed present different textured patterns to the observer, and therefore allow the sign designer greater latitude in the design and layout of the sign. Portions of the sign material may extend outwardly or downwardly from the sign body, for connection to the ground or any other secondary support structure. The materials of construction of the sign apparatus significantly enhance the longevity of the structure, as compared to the sandblasted wooden structures currently being used which are subject to rot or decay.

Abstract: Apparatus is disclosed for use in the exercise of the human body, which comprises a fiberglass pultruded shape of a predetermined oblong geometry with an extruded rubber compound sheath formed about the exterior thereof over the entire length of the fiberglass pultruded shape. The fiberglass pultruded shape has fiberglass filaments dimensionally stabilized in a hardened resin system. Material properties of the filaments in the resin system are selected such that the ultimate elongation design value of the filaments and the resin system is greater than the actual maximum elongation of the filaments and the resin system when the fiberglass member is flexed in the exercise process. Also, the resin is selected for toughness sufficient to provide a useful flexural fatigue life.

Abstract: A sucker rod construction including a connector member being formed to define a rod receptacle having a closed axially inner end and an open axially outer end. The rod receptacle has a plurality of axially spaced, tapered annular surfaces. The end of a cylindrical fiberglass rod is received within said rod receptacle through the outer end and cooperates therewith to define an annular chamber between the outer surface of the end of the rod and the tapered annular surfaces. A bonding material is positioned in the annular chamber and bonds the outer surface of the end of the rod and the tapered annular surfaces. Each of the annular surfaces has an angle of taper with respect to the outer surface of the fiberglass rod, and each angle of taper is progressively less toward the open end by at least one and one-half degrees.

Abstract: A rack for printed circuit boards is disclosed. The rack has a first wall with a circuit board engaging surface and a second wall with a circuit board engaging surface disposed generally perpendicular to one another. The two surfaces are rigidly fixed together at right angles to each other and the board engaging surfaces are fixed to and supported by a first lateral flange and a second lateral flange. The first board engaging surface has ribs at the side edges for engaging the edges of boards and a recess is formed between the two board engaging surfaces which receives projections on the boards, debris, liquids or other foreign material. For manual handling and quick access to boards, the rack can be used alone on a desk top or the like wherein bottom board edges rest at an acute angle to the desk surface. For mechanical handling and shipment of boards, the rack can be used in opposed pairs adjustably connected and within a container wherein bottom board edges rest parallel to support surface.

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: Reinforced plastic (FRP) panels of substantial width are manufactured continuously in a machine utilizing two stainless steel belts, with an inner belt trained about a driven rotating heating drum and an idler sheave. An outer belt is trained about the inner belt as it passes around the drum and also about three idler sheaves, two being employed to direct the outer belt about the inner belt and the third being employed for tensioning and tracking purposes. An additional idler roll is employed as a nip roll where the two belts join substantially tangent to the heating drum. Both belts may have substantially horizontally flights for application of heat curable resin. A fiberglass or other reinforcement mat is fed into the nip. The resin such as unsaturated polyester may be fed in controlled doctored amounts of liquid form to provide a bead or puddle at the nip into and through which the mat is drawn. The heat of the drum initiates the cure to form a wide controlled thickness reinforced sheet.
