Abstract: A method of playing a card game that includes providing a deck of playing cards, assigning a position value to positions at a playing area, dealing a predetermined number of cards to at least one player at least one pre-selected position, and determining if a player is entitled to a payment and/or value based upon at least one dealt card in either the player's hand or a house hand matching at least one assigned position value. Alternatively, bonus values are determined based upon cards dealt to the dealer as opposed to being based upon playing positions.

Abstract: A chuck for use with a manual or powered driver that may also be used for hammer drilling. The chuck is constructed so that during normal operation for its intended purpose, the jaws holding a shaft for a tool do not loosen. The chuck includes at least one pawl to engage teeth on a gear ring such that rotation of a ring driver in a jaw gripping direction causes the gear ring to rotate. When the jaws tightly grip the shaft, the gear ring will frictionally engage a portion of the chuck so that the gear ring is rotationally locked to the chuck body. At the same time, the pawl engages the gear ring such that rotation of the ring driver and thus movement of the jaws in a non-jaw gripping direction is prevented during normal use of the hammerlock chuck.

Abstract: A thread for expandable downhole tubular connections is disclosed. It features a locking pattern on the pin and box, which engages upon expansion of the connection. The locking pattern compensates for longitudinal shrinkage away from a torque shoulder, as a result of expansion. A resilient seal can be incorporated into the design with pin to box clearance disappearing around the seal as a result of expansion. Resilient seals can be used in tandem to trap atmospheric pressure between them. The wellbore hydrostatic pressure helps engage the locking feature by pushing the box into the pin, helped by the trapped low pressure between the seals.

By mating the brake into an annular trough, that is, by placing it between two walls, the rotation of the segment can continue only until points on the brake mure between the two walls. Rotation of the segment in response to increasing thrust pressures can thereby be arrested before the rotation causes the segment to bear on the spigot with a radically inward force great enough to penetrate the spigot.
