The present invention relates generally to mill blank constructions to facilitate the manufacture of dental restorations. A given mill blank is formed in a shape (i.e. with a given geometry) that has been predetermined to reduce material waste when the mill blank is machined into the final part. A set of two or more blanks each having such characteristics comprise a smart blank “library.” In one embodiment, a smart blank library includes a sufficient number of unique blanks such that, when the geometry of the designed restoration is known, the smart blank with a highest yield can be selected for use in milling the restoration. The “yield” of a given smart blank represents the amount of material of the smart blank that is actually used in the final restoration. Automated processes for smart blank inventory management and smart blank selection are also described.

A method of deactivating land mines buried in ground comprises projecting high-pressure water jets into ground, cutting through ground with the high-pressure water jets, and making at least one cut through a land mine or cutting through at least one land mine that had been under the ground, the cutting of the land mine reducing the performance of the land mine. The method may reduce the performance of the land mine by rendering the land mine inactive to normal detonation procedures for the land mine. To reach as many surface areas on the buried landmines, it is preferable that at least two high-pressure water jets are spaced apart are used to cut through the ground. The method may be practiced with the high-pressure water jet being carried on a vehicle and cutting is done in a line that is formed at least in part by movement of the vehicle over the ground while the high-pressure water jet is cutting ground. An apparatus for the reduction in effectiveness of land mines buried in ground may comprise a self-contained push-cart unit or a unit attached or attachable to a vehicle. A complete system could comprise a vehicle having a source of liquid, a high-pressure pump to move the liquid under high pressure, a nozzle directing a liquid jet path for the liquid, a support for the nozzle, abrasive delivery system, and nozzle being controllable to direct the liquid towards the ground while the nozzle is fixed relative to the vehicle.

The present invention integrates the use of pre-manufactured structures with minimal on-site installation and lift-slab construction to achieve the construction of multi-story buildings. The pre-manufactured structures are designed to be readily integrated with both horizontal and vertically adjacent building components, including lift-slab components, so that multiple building stories may be readily and securely stacked, one on top of the other. The present invention advantageously permits top- down lift-slab construction for multi-story buildings. The present invention also provides for the development of flexible design plans for institutional, residential, office and other types of buildings. The present invention advantageously provides for easier, more efficient, faster, cheaper, safer, higher quality and more consistent, environmentally advantaged, energy-efficient, easier to maintain, intelligently designed, and customizable multi-story building construction.

The present invention relates to a system and methodology facilitating material-driven processing in an industrial controller environment. Various models supported by database objects are provided to automatically and dynamically map inventory systems/processes to control systems/process such as in batch or recipe operations. A material model is provided that tracks to an inventory database and includes such aspects as defining material types and containers to house such materials. An area model maps the material model to possible units and equipment modules to process the materials. These models include phased-based parameters that define amounts of material that flow into and out of a determined area for processing the materials. Before, during and/or after automated manufacturing operations, object binding operations occur between material-based servers associated with an inventory system and batch servers associated with a process-control system. Such binding includes Just-In-Time or on-demand binding at run time, and relates material requirements of a recipe (or batch) to the units and equipment that are available to produce the recipe.

A method of constructing a preform for use in forming a machined structural assembly is provided. The method includes determining the dimensions of the machined structural assembly. First and second structural members are selected based on the predetermined dimensions of the machined structural assembly. The first structural member is positioned adjacent the second structural member so as to define at least two contact surfaces. The contact surfaces of the first and second structural members are friction welded to construct the preform such that the preform has dimensions approximating the dimensions of the machined structural assembly to thereby reduce material waste when forming the machined structural assembly. A machined structural assembly having predetermined dimensions is formed from the preform by machining away excess material.
