    摘要: An earth boring bit has a bit body having a depending bearing pin. A cone has a cavity rotatably mounted on the bearing pin. A seal groove is formed in the cavity of the cone. An elastomeric seal ring is located within the groove and forms a seal between a base of the groove and the bearing pin. The seal ring has two side surfaces, each spaced from one of the side walls of the groove by a clearance. Elastomeric protuberances protrude from each of the side surfaces of the seal ring for non-sealing contact with one of the side walls of the groove.

    摘要: An earth-boring bit has a seal assembly with a seal face having a DLC coating. The seal assembly locates between a bearing pin and a cone of the bit. The seal assembly has at least one rigid ring that rotates against a mating surface. The DLC coating is diamond-like carbon that may be coated by different processes onto either the ring, the mating surface, or both.

    摘要: A rock melting penetrator is provided with an afterbody that rapidly cools a molten geological structure formed around the melting tip of the penetrator to the glass transition temperature for the surrounding molten glass-like material. An annealing afterbody then cools the glass slowly from the glass transition temperature through the annealing temperature range to form a solid self-supporting glass casing. This allows thermally induced strains to relax by viscous deformations as the molten glass cools and prevents fracturing of the resulting glass liner. The quality of the glass lining is improved, along with its ability to provide a rigid impermeable casing in unstable rock formations.
