  • Patent number: 6733011
    Abstract: A method of playing a Super Baccarat card game involves a fixed number of players in one round of game, wherein a Host is selected from the players to play against the rest of the players. The Host and the players invest a Capital and Investments respectively wherein each player selectively invests the respective Investment at a BANKER position or a PLAYER position. Two cards are dealt to the BANKER position and the PLAYER position respectively. By determining and comparing total point values of the BANKER cards and the PLAYER cards, which has a higher total point value wins the round of game. An action player is determined by an action number according to the higher point value, so as to determine which of the player to play against the Host and start to collect or payout the Investment until the Capital is totally paid out.

  • Patent number: 6732514
    Abstract: A hydraulic jack with dual pump system includes two fluid reservoirs, two pumps for pumping the hydraulic fluid from the fluid reservoirs to an inner fluid chamber of a hydraulic cylinder respectively, and two sequence valves each opening at a predetermined control pressure to enable the hydraulic fluid flowing from the inner fluid chamber back to the respective fluid reservoir, wherein the control pressure preset at the first sequence valve is smaller than that preset at the second sequence valve. Therefore, at a no load condition, the pumps are pumping the hydraulic fluid to the inner fluid chamber to speed up the lifting up of the lifting arm, and at a load condition, the first sequence valve is opened by means of a loading pressure while the second pumping means keeps pumping the hydraulic fluid to the inner fluid chamber to substantially lift up the lifting arm.
