Abstract: A mortarless block system for forming walls from blocks which are stackable in sequential rows upon each other. Upper rows of blocks positioned upon lower rows are securable by positioning of support rods through aligned passages thereof. The passages extend between upper and lower notches in each respective block. The support rods are engaged to connectors which are sized to fit completely within the notches to thereby leave the upper and lower surfaces of each lower row flush to stacking overhead rows thereon.

Abstract: A block used for building a structure such as a wall, floor or roof comprises deep recesses in the top and bottom surfaces. A bracket is attached between two blocks by inserting the flanges of the bracket into the deep recesses, thereby creating a central void between the two blocks. The block also comprises protruding portions and recessed portions wherein the protruding portion of one block fits snugly within the recessed portion of an adjacent block.

Abstract: A method and a system for developing/customizing web-based collaborative applications are provided. The system is a scalable, secure, enterprise class software platform for web and email-based collaborative application. The system provides a platform to develop and customize as well as deploy these applications. The application engine of the system can leverage libraries of pre-existing applications or rapidly build entirely new that allow focusing on the solution to customer needs. A web-based application built employing the system's application engine is a composite of definitions of application components. Browser-based wizards are provided by the application engine of the system to define application component types. The application engine of the system also provides for combining/tying these application component types together.
