Abstract: This invention relates to catalysts containing crystalline alumino-silicate zeolite and hydrothermally treated silica-alumina cogels and the employment of the same as cracking catalysts.

Abstract: The invention relates to bore hole drills employing spaced shaped cutters in arrays separated by fluid channels in which there are positioned arrays of nozzles suitable for bit cleaning and detritus removal action.

Abstract: A hanger for supporting dual tubing strings in a well casing from hanger mandrels which can swivel to facilitate threadedly connecting each mandrel to its associated tubing string. The hanger includes an orienting sleeve for receiving safety shut-off valves, the sleeve being adapted to swivel with respect to the rest of the hanger, making it easier to assemble the hanger onto the running and setting tool used for setting the hanger in the casing.

Abstract: A hanger for supporting dual tubing strings in a well casing from hanger mandrels which can swivel to facilitate threadedly connecting each mandrel to its associated tubing string. The hanger includes an orienting sleeve for receiving safety shut-off valves, the sleeve being adapted to swivel with respect to the rest of the hanger, making it easier to assemble the hanger onto the running and setting tool used for setting the hanger in the casing. The running and setting tool is releasably secured to the hanger. By imposing fluid pressure on the setting tool, the tubing hanger slips are expanded against the casing.

Abstract: Stabilizer apparatus for a rotary drill string, or other running string, including a body structure forming part of the rotary drill string and a stabilizer positioned on an end portion of the body structure, the stabilizer comprising a stabilizer sleeve having a conical interior surface shrink-fitted onto a mating external conical surface of the body structure by fluid pressure actuated or hydraulic means, permitting a safe, strong interconnection between the stabilizer and the drill string body structure. The stabilizer can be readily removed when necessary and replaced with another stabilizer similarly shrink-fitted onto the drill string body structure. The lower end of the stabilizer is internally upset and is received in an annular groove in the body structure, or under the lower end of the body structure, providing a large contact area between the stabilizer and a device threaded on the body structure which engages the lower end of the stabilizer.

Abstract: A tool joint for well drilling pipe includes a body having a wear protector including a split ring disposed in an annular groove in the tool joint body, the ring segments being welded together and to the groove portion of the body. Hardmetal elements secured in the outer periphery of the ring are irregularly distributed, with the distribution or density of the hardmetal elements being greatest adjacent to the end of the tool joint body and progressively less inwardly from the end of the tool joint body.

Abstract: A cosmetic applicator, such as a lipstick applicator, includes an inner cosmetic holder or cup in which a cosmetic mass or lipstick is securable and which is disposed within an outer cylindrical tubular member, the holder or cup being shiftable in forward and rearward directions to propel the cosmetic mass or lipstick out of the tubular member or to retract it therewithin. A transparent enclosing cap can be moved over the tubular member when the holder and cosmetic mass or lipstick are in retracted position to protect the internal mass or lipstick. The base of the cap carries an opaque dummy lipstick top simulating the shape of the lipstick or other cosmetic mass disposed in the holder or cup, the dummy top having a shade matching that of the lipstick. The dummy lipstick top can be seen through the transparent cap to indicate the shade of the lipstick without removing the cap. The dummy top covers the outer end portion of the lipstick and guards or shields it against the harmful effects of ultraviolet light.

Abstract: A cosmetic applicator, such as a lipstick applicator, includes an inner cosmetic holder or cup in which a cosmetic mass or lipstick is securable, and which is disposed within a carrier sleeve fixed to a base and surrounded by a tubular member having an internal helical groove or thread receiving one or more cup keys extending through longitudinal slots in the sleeve into the helical groove, or meshing with the internal helical thread, so that relative turning between the tubular member and the carrier and base effects advancing and retracting movements of the cup and cosmetic mass along the carrier sleeve. The carrier sleeve has an unslotted forward extension on which an enclosing cap can be mounted which has substantially the same external diameter as the tubular member and base, resulting in an applicator of greater slimness than prior applicators, better appearance and requiring less material.

Abstract: Apparatus for and method of gravel packing a well, wherein a well liner is run into a well bore on a hydraulically set packer assembly which is releasably supported on a setting tool which provides a fluid flow crossover and seals which are selectively positionable within the packer body and a sealing receptacle in the liner. A ball is dropped to enable pressure to set the packer. The running tool is released and moved upwardly to a circulating position at which fluid can circulate downwardly through the running pipe string and the running tool, through the crossover to the annulus outside the liner to deposit gravel, the fluid flowing upwardly through the crossover and past the packer into the annulus outside of the running pipe string. The running tool is then moved further upwardly to position the seals for reverse circulation of fluid down the annulus outside of the running pipe string and through the crossover into the liner, and then back through the crossover into the running in pipe string.
