  • Patent number: 5743740
    Abstract: A multi-level educational game apparatus and method for teaching children and adults language, mathematical, and other skills. The educational game includes a board and a plurality of cards. The board comprises a plurality of rows and columns, each having a letter, word, or picture imprinted thereon. The cards have letters, words, numbers, symbols, or pictures imprinted thereon that correspond to the participant's boards. The board game includes multi-levels of difficulty corresponding to varying individual language and other ability levels. An instructor will read aloud the card and give a brief explanation of the card's contents. When a participant recognizes the cards contents on his board, he will cover the respective box with a marker. The object of the game is to complete a row or other predetermined sequence of boxes prior to another participant.

  • Patent number: 5702079
    Abstract: An apparatus and method for cleaning, inspecting and maintaining media disposed within a biological aeration treatment media support frame. The apparatus consists of a frame connected to legs, x shaped cross-members, lifting hooks, lock bar supports and lock bars. The x shaped cross-members are mounted to the sides and bottom of the frame for the support of media as well as contributing to the strength of the frame thus protecting it from external forces. The lifting hooks permit the operator of the biological aeration treatment support frame to remove the frame in an effortless manner when cleaning, maintaining and inspecting the media. The lock bars are supported by the lock bar supports, which, in turn, maintain the media within the frame hence not allowing the media to float around in the wastewater treatment compartment. The lock bar support handle can also be used as a lifting hook. The lock bars are swivel mounted on the lock bar support to allow easy access to the media.

  • Patent number: 5659768
    Abstract: The graphical time representation of tasks for depicting both graphical representation of tasks and alphanumeric representation of tasks. The graphical and alphanumeric representation of tasks are linked so that designation of a timebar results in the designation of a corresponding timecell and vice versa. The timebars and timecells can be manipulated in a coordinated manner. Timebars automatically display symbols indication of the type of manipulation permitted upon designation by a user.

  • Patent number: 5599452
    Abstract: A wastewater treatment plant for removal of organic matter, suspended solids and other pollutants comprising a pre-treatment chamber, a biofilm-aeration chamber and a settling chamber. Biofilm grows on biofilm support structure which is stationary and submerged in the mixed liquor of the biofilm aeration chamber. The combination of submerged or surface aeration and suspended solids particle size reduction occurs thereby creating a sufficient fluid flow within the biofilm aeration chamber. This combination of sufficient fluid flow, and reduced size suspended organic particles results in the efficient digestion of organic matter and pollutants by the biofilm growing on the biofilm support structure submerged in the biofilm aeration chamber. This results in a vastly more effective digestive process than conventional processes producing no sludge. Further, resulting treated effluent has a high dissolved oxygen content and low BOD and SS.
