Inventor: MCINERNEY PETER J
IPC: G06F9/45
Filed: 1994-01-03
Abstract: A human oriented object programming system provides an interactive and dynamic process for the incremental building of computer programs which facilitates the development of complex computer programs such as operating systems and large applications with graphic user interfaces (GUIs). The program is modeled as a collection of units called components. A component represents a single compilable language element such as a class or a function. The three major functionalities are the database, the compiler and the build mechanism. The database stores the components and properties. The compiler, along with compiling the source code of a property, is responsible for calculating the dependencies associates with a component. The build mechanism uses properties of components along with the compiler generated dependencies to correctly and efficiently sequence the compilation of components during a build process.

Patent CA-2159527-A1 (CA)
Title: Container and Lid for Container
Inventor: JAMISON BARRY
IPC: B65D25/00
Filed: 1995-09-29
Abstract: A container has a drop gate and lids that open along hinge joints formed at the upper end of the side walls.  The drop gate is formed in one end wall and the lids can also be opened half way from the end wall in which the drop gate is formed.  In this way, access to the interior of  the container can be gained through the open drop gate and the open half of the lids so that the container can be used as a shelf box or hopper in a flow racking system.  Further, when the lids are opened along their respective side wall hinge joints, the container can be used as a distribution tote.  When the container is also used as a bulk shipper by vendors or suppliers, the container can perform three functions in a distribution system.  Specifically, the container can be first used as a bulk shipper, then, without unpacking the goods, the container can be shelved on a flow racking system from which orders can be selected at a distribution center. Finally, the container can be used again for shipping the goods from the distribution center to retail outlets and returned to either the distribution center or suppliers in a nested stack.
