  • Patent number: 6046282
    Abstract: Reactive diluents comprise the amide and/or imidazoline reaction products of low molecular weight carboxylic acids, such as acetic acid, and polyalkyleneamines, such as 2-aminoethylpiperazine (AEP) and triethylenetetramine (TETA). The reactive diluents are prepared by condensation reaction of the carboxylic acid and the polyalkyleneamine at elevated temperature generating a mixture of unreacted polyalkyleneamine, amides and/or imidazolines. The reactive diluent reaction products are used to reduce the viscosity of high viscosity polyamidoamines prepared from fatty dimer acids and polyethyleneamines. Also disclosed is an epoxy composition comprising the epoxy curative composition of a polyamidoamine curing agent reduced in viscosity by the addition of the reactive diluent reaction product and an epoxy resin, such as the diglycidyl ether of bisphenol A.

  • Patent number: 6007424
    Abstract: A method, device and system are set forth for playing a new game of Pai Gow Poker. The method includes dealing seven cards to the dealer and each player, the players and dealer each from those seven cards assembling a five card high hand and a two card low hand. For the player to win their wager, both the player's high and low hands must outrank the dealer's hands according to the ranking of hands of Poker. For a push the player's high hand must have a higher ranking the dealer's and be Jacks or better. All other hands are losses. The method provides for greater payoffs if the player has one of a plurality of payoff qualifying holdings. The device includes a processor programmed to play the game according to the method. The system provides for linking devices to amass a progressive jackpot should the player obtain a qualifying holding.

  • Patent number: 6008313
    Abstract: Compositions of amine terminated polyamide resins useful for curing epoxy resins are disclosed comprising combinations of fatty mono-acids, dimer acids, polyethyleneamines, and piperazine ring containing polyamines having an N--H functionality of 2 or 3 per mole selected from the group consisting of piperazine, or N-aminoalkylpiperazine, where the alkyl chain is a C2 to C6 alkyl chain, wherein the ratio of equivalents of fatty mono-acid to dimer acid can range from about 0.001:1 to about 1:1, the ratio of moles of piperazine ring containing polyamine to polyethylene amine can range from about 0.1:1 to about 1:1, and the ratio of moles of polyamine to equivalents of acid can range from about 0.6:1 to about 1.2:1. Coating compositions comprising these polyamide resins are also disclosed.
