Abstract: A casino game, based on the rules of poker, wherein each player is dealt five cards, with an option to utilize a sixth card to improve the five-card hand. The game provides a player with three opportunities to win: 1) head-to-head competition against the dealer, with the higher poker hand winning; 2) competition for a common pot among the players, the amount of the pot increasing until a player has a hand of three-of-a-kind or better; and 3) bonus payments for long-odds hands (e.g., straight or better). Because no player has an opportunity to increase his/her wager during play, the game proceeds rapidly.

Abstract: Slots is a game in a box and is a multi-player manual slot game designed to simulate mechanical and computerized casino slot machines and computerized slot games. This game uses game tiles, chips, pay tables, and interchangeable sets of game tiles to enhance variety, vary the odds, add bonuses, and incorporate current trends. Players draw tiles face down from a pool and place them in a matrix on a tray which forms pay lines according to the game rules. The object is to match tiles along the predetermined pay lines on the pay table. The bank pays winning pay lines; the bank collects losing wagers. Allowing the players to select tile placement in predetermined rows and columns of the matrix enhances odds of winning and maintains interest. Odds of losing are controlled by placement-as-drawn in the final column or columns.

Abstract: In order to increase in concentration of HC in an exhaust gas due to an axial gap between a ring groove and a piston ring, when an internal combustion engine is at a lower temperature, particularly, during the starting or the low-speed operation of the internal combustion engine in which the moving speed of a piston is lower, a restricting ring having a radially outward tension is inserted in a wedge shape into between axially opposed surfaces of a ring groove and a piston ring so that in a lower-speed operational range of a piston, the axial movement of the piston ring within the ring groove is restricted by the wedging action of the restricting ring, and in a higher-speed operational range of the piston, the wedging action of the restricting ring is removed by a floating force of the piston ring generated with the descending movement of the piston.

Abstract: A hydrodynamic shaft seal formed with a spiral hydrodynamic channel in which successive turns of the channel are of progressively diminishing volume toward an air side of the seal. The channel is made by forming a spirally extending first cut in a surface of the seal, and forming a spirally extending second cut in the surface of the seal adjacent to the first cut such that the first and second cuts intersect below the surface of the seal to produce a spiral channel. The spiral of the first cut has a lead different from the lead of the second cut such that the channel is of progressively diminishing volume along its length. Alternatively, the second cut may have the same lead as the first cut for the first few turns, after which the lead of the second cut may be reduced, to provide a channel of constant volume for the first few turns, followed by a channel portion of reduced volume.

Abstract: A fluid coupling device employs a male spherical member with a fluid receiving bore and a female housing. The spherical member abuts two axially spaced Teflon ring seats between the member and the housing in the housing chamber. The ring seats reduce friction between the member and the housing, and axially retain the member in the housing with no metal to metal contact. A first O-ring provides fluid sealing between the spherical member and housing inner wall in the chamber. A hose receiving nipple member with a fluid receiving bore has a threaded concave end with a peripheral region that engages the first O-ring to hold the O-ring against the spherical member, one of the ring seats and housing chamber wall to seal the interface between the spherical member and housing. The nipple member has a flange which abuts the housing to limit squeezing action on the O-ring to ensure sufficient contact of the O-ring and mating surfaces to obtain a good seal without creating excessive friction loads.
