Abstract: A retail display hanger for supportively displaying a fluid container and a secondary component, where the fluid container has a neck, typically threaded, with a cap, which is likewise complementary threaded.

Abstract: A foamed rigid bottom sanding block includes a sanding block formed of polyfoam material having a bottom portion with an integrally formed rigid member made of a material to lend weight as well as rigidity to said bottom portion, said rigid member nearly spanning a length and a width of said bottom portion and which encased within said polyfoam material, an upper portion of said sanding block having a handle which protrudes from said bottom portion and is made of said polyfoam material. A method and sanding block formed by the method are included.

Abstract: A drilling tool connection includes a male pin, a female box connector, and a locking pin. The male pin includes a hexagonal outer perimeter, at least a portion of the pin having a cylindrical bore along a longitudinal axis of the pin, where the pin has a transverse slot formed transverse to the longitudinal axis of the pin. The box connector element includes a circular outer perimeter, where at least a portion of the box connector element has a hexagonal aperture aligned with a longitudinal axis of the box. The box connector element has at least one transverse bore formed in the box transverse to the longitudinal axis of the box, and the hexagonal aperture of the box is adapted to receive the hexagonal portion of the male pin. The locking pin is insertable through an aperture defined by the slot of the pin and the bore of the box.

Abstract: A universal joint assembly includes an assembly housing, an assembly cap coupled to the assembly housing, a rotatable mandrel, a plurality of substantially spherical drive balls, and a floating washer. The assembly housing has a plurality of pockets formed in an interior surface of the assembly housing. The rotatable mandrel is fitted within a cavity defined by the assembly housing and the assembly cap and has a plurality of pockets configured to partially receive the drive balls. The substantially spherical drive balls are rotatable within the cavity about a central axis of the mandrel. A substantially circular groove formed in the cavity is defined by a proximal end of the assembly cap and an interior wall and a shoulder of the assembly housing. The floating washer is disposed within the substantially circular groove and configured to radially displace within the groove.

Abstract: A downhole drilling motor beating assembly includes a tubular mandrel adapted to connect to a rotational power output of downhole motor. The bearing assembly includes a mandrel having: an upper end proximal to the downhole motor, a lower end with a pin connection distal from the motor, and a longitudinal passage through the mandrel from the upper end to the lower end. The assembly further includes at least one circumferential ring projecting radially outward from an other surface of the tubular mandrel. The ring has and upper shoulder and a lower shoulder and a radial surface. A circumferential upper thrust bushing contacts the upper shoulder of the ring and a circumferential lower thrust bushing contacts the lower shoulder of the ring. An upper thrust beating contacts the upper thrust bushing and a lower thrust bearing contacts the lower thrust bushing. A tubular bearing housing includes a longitudinal passage from an upper end of the housing to a lower end of the housing.
