Abstract: A rotationally molded type III traffic barricade system has a plurality of bases and uprights adapted to be assembled in a shipping configuration, a transportation configuration and a deployment configuration. Each upright has recess for receiving a warning light and a cushion adjacent the recess for absorbing the impact force of a collision between the barrier and a vehicle. Recesses are also provided in the upright for receiving barricade panels in such a manner that the chance of damage to the panels is minimized during transportation, etc. Dimples in the recesses and opposing cones on the rear surface of the upright guide an assembler as to where to drill holes for bolts that mount the barricade panels to the uprights.

Abstract: There is disclosed a dry bulk hopper system that includes a generally frustoconical bottle and a base having a tapered wall that defines a cradle for holding the bottle. The bottle has locking tabs disposed at bottom end thereof that cooperate with engagement ledges to secure the bottle to the base when the bottle has been received into the base in a first orientation, but not in a second orientation. Extruded support columns are disposed inside an interior of the base to distribute loads created by material in the bottle when the system is raised by a forklift.

Abstract: An asymmetric mold core for forming curved floor openings in pallets is taught.

Abstract: An asymmetric mold core and method for use for forming curved floor openings in pallets is taught. The mold core contains: a base, the base attachable to a frame in a rotomold, a bottom section integral at a distal end to the base and a top section integral at a distal end to the base. Both the top section and the bottom section have convex radial curve shape, but the top section curve and the bottom section curve are positioned by having different centers of rotation so when the core is actuated it is only actuated around the center of rotation about the bottom curve which causes the top cure to drop away from the upper molded surface.
