  • Patent number: 7857199
    Abstract: An apparatus and method for enhancing the security of a cluster box unit which includes a protective enclosure, internal cabinetry, door, hinge and locking system. The cluster box unit may also include outgoing mail compartment doors that are heavily constructed and rigidly reinforced, with the locks carried thereon protectively shielded, and with the extensible bolts of these locks being engaged by brackets that not only lock the outgoing mail compartment doors but also the master loading doors of the cluster box units. The cluster box unit may also include master loading doors are provided with hinges that extend the full height of the doors—hinges that are defined by pivotally interfitting elements of extrusions that very sturdily mount the master loading doors, that prevent prying or bending the doors in the vicinities of their hinges.

  • Patent number: 7850515
    Abstract: A card game and video gaming system includes a matrix of card positions in addition to cards dealt for a player's hand. The player may select betting lines or line paths in the matrix to play and set a wager for the selected line paths. Line paths may include a variety of line configurations including rows and/or columns of the matrix. One or more cards may be selected for retention from the player's hand and combined with cards in each of the selected line path of the matrix to form patterns. The matrix may activate card positions or cards depending on line path selections as well as a number of cards selected for retention.

  • Patent number: 7788924
    Abstract: A stack system and method for in-line geothermal and hydroelectric generation from recovered natural gas-fired water/steam process waste heat. The stack system and method is a new way of reusing natural gas fired water/steam process waste heat to make more electricity from the same Btu inputs. The stack system and method uses warm industrial demineralized water from various sources, a micro-managed combined stack flue system and specific terrain to ring out every bit of energy possible from traditional, heretofore, acceptable wastes. The stack uses two marginal waste heat sources to make one significant heat source for additional fossil fuel-free generation. This stack is unique in that it incorporates tandem, geothermal and hydroelectric generators. The stack can be applied to closed-loop (Power Stack) and open-loop (Desalination Stack) processes.
