Abstract: The method of playing a card game according to the present invention is operated among multi-players, a Dealer and a Banker. The game is played with 12 decks of cards from A to 6, hence there are 288 cards altogether. All cards from 7 to K and Jokers are removed. According to the method of the present invention, each player places a wager before the Banker shakes the Dice Cup which contains 3 dices to determine where the action starts. The Dealer will deliver 4 cards unexposed to each player. The players set their hands by making a front 2 card hands and a back 2 card hands. The back 2 card hands must rank higher than or at least, be even to the front 2 card hands. After all players have set their hands, the Dealer will then reveal the Banker's cards (front & back) the way the Banker wants them to be set. Then the Dealer will compare the cards of each player to the Banker's cards and winners or losers or pushers are determined based on the comparison.

Abstract: Advantageous seal systems (1500) are provided that include a barrier member movable relative (1504) to a shaft (1550) to allow sequential engagement of resilent seal members (1506), e.g., lip seals, with the shaft. Movement of the barrier member (1504) may be effected manually or through introduction of pressurized fluid to effect piston-like movement. The disclosed seal assemblies may include an automatic leak detector and may utilize such leak detection to effectuate automatic movement of the barrier member. The barrier member may be moved relative to the shaft while the shalt is in movement, e.g., rotating or reciprocating, thereby permitting seal maintenance without interruption in operation. As seal members are sequentially brought into sealing engagement with the shaft, the previously engaged seal members contribute to the sealing performance of the seal assembly, although no longer effective to establish a stand-alone seal with the shaft.

A leaf spring is welded at one end to each brush seal segment and has first and second circumferentially extending curved portions. The first curved portion extends lengthwise of the spring from the welded end to engage the base of the groove at a location intermediate the length of the spring. The second curved portion engages the radial outer face of the segment adjacent the tip of the spring. All of the segments are thus biased for movement radially inwardly toward the rotating component, enabling pressure forces during operation to maintain the brush seal segments properly located to ensure the seal.

Optionally, a second locator spring, also a wave spring, may be disposed between the piston ring and the seal support structure for urging the piston ring in a radial direction.

Abstract: This invention relates to the use of elastomers with the sealing element of reciprocating gas compressor valves to increase the reliability of the gas tight seal within the reciprocating gas compressor valve and to increase the useful life of reciprocating gas compressor valve. The elastomeric material is either used as a coating layer on the sealing element of the reciprocating gas compressor valve, or as the entire sealing element. The elastomeric material acts as a cushion to reduce the wear on the sealing element, provides a superior gas tight seal, and is more tolerant of entrained dirt or liquids in the gas stream thereby increasing the operable life of the reciprocating gas compressor valve. Reducing the mean time between reciprocating gas compressor valve failures results in longer reciprocating gas compressor run times for the user, increased revenue generation for the user and safer operation of said equipment.

Abstract: An edge coated gasket includes a base sheet made of compressible gasket material and having opposed faces and an interior edge surrounding and defining an aperture. An edge coating of polymer or other material is disposed on and seals the interior edge of the base sheet and may project beyond the facial planes of the base sheet to define protruding rims extending around the aperture. Face coatings may also be applied to one or more of the faces extending in relatively narrow strips around the aperture of the base sheet. When clamped between flange surfaces, the edge coating engages, conforms to, and seals against the flange surfaces to provide a seal against both interfacial and intersticial migration of fluid past the gasket. At the same time, the inherently good compression failure resistance of the compressible gasket material of the base sheet is preserved. Thus, a gasket with enhanced sealability and compression failure resistance is provided.
