Abstract: A tri-fold plastic egg carton for protecting jumbo eggs in both oriented and non-oriented positions. A cell base and cell cover are hingedly connected in a closed position with the cover over the base to form a complimentary 2×6 matrix of cell pockets for holding individual eggs. A lid is hingedly connected to another edge of the base for closing over the assembled cover and base. The non-hinged peripheral edges of the base, cover and lid form a trim perimeter having a turned up lip edge, the lip edges mating when the carton is in the closed position to increase the carton strength. The carton can accommodate a full range of jumbo eggs, and accept a variety of smaller size eggs, while fitting within standard cases and half-cases.

Abstract: A mounting pad and method for mounting a plurality of light bulbs in a compact and shock resistant arrangement for storage in a box and for transport, the plurality of light bulbs being arranged in rows generally parallel to each other by mounting the terminal ends of a row of light bulbs in a mounting pad disposed at each terminal end of the bulbs and stacking successive rows of mounted bulbs one on top of each other.

Abstract: Porous leach pipe and method for leaching metals from mining ores. The porous pipe may be buried beneath the surface of a pile of mined ore, providing a more even and uniform distribution of the leaching solution across the pile, increasing metal yields, reducing water consumption and eliminating pooling and ponding of the solution on the top of the piles as occurs with prior art drip line emitters.

Abstract: Plastic egg cartons having mating cell and lid posts for improved egg protection. The carton has a base tray and hinged lid, the tray including a plurality of cells for receiving individual eggs, and the tray having a plurality of cell posts each formed at an intersection of four adjacent cells as an extension of the sidewalls of the four adjacent cells. Preferable, each cell post has four generally planar ramp surfaces, one disposed respectively on each of the four sidewall extensions. The lid has a plurality of lid posts for mating with the cell posts when the lid is in a closed position.
