Abstract: System and method provide wireless distributed lighting control systems implementing a secure peer-to-peer, self-organizing and self-healing mesh network of actuators and system inputs. The system and method can be designed specifically for indoor and outdoor lighting where actuators include in-fixture, on-fixture and circuit control modules with ON/OFF and full range dimming capabilities, and system inputs include occupancy/vacancy sensors, daylight sensors and switches. A unique messaging protocol facilitates wireless and wired communication between actuators and system inputs, and provides web-based commissioning and monitoring of the lighting control system using a wireless access point accessible from a local network or Internet which can provide an intuitive and easy to use Graphical User Interface (GUI).

Abstract: A method for producing metal carbide grade powders which comprises forming a wax mixture consisting essentially of in percent by weight about 5 to about 15 paraffin oil, with the balance being an esterified wax and paraffin, heating the wax mixture to a temperature above the melting point to melt the wax mixture and maintain it in the molten state, forming a powder-wax mixture consisting essentially of metal carbide powder, a binder metal, and the wax mixture while heating to a temperature above the melting point of the wax mixture to maintain the wax mixture in the molten state to result in a uniform distribution of the wax mixture on the carbide and binder metal particles, forming a slurry of the powder-wax mixture and water, attritor milling the slurry at a temperature below the melting point of the wax mixture, and removing water and agglomerating to produce metal carbide grade powder wherein a densified article made therefrom exhibits less linear shrinkage than articles made from carbide grade powder abs

Abstract: A method for producing metal carbide grade powders suitable for isostatic compaction which comprises combining a binder metal powder with an esterified wax and heating the wax to a temperature above the melting point of the wax to melt the wax and maintain it in the molten state to form a first mixture, with the amount of wax being sufficient to result in a level of wax in the subsequently produced second mixture of no greater than about 1/2% by weight, combining a metal carbide powder component with the first mixture while maintaining the wax in the molten state, forming a slurry of the second mixture and water, attritor milling the slurry at a temperature below the melting point of the wax, and removing water from the resulting attritor milled mixture to form the metal carbide grade powder.

Abstract: A method is disclosed for producing metal carbide grade powders, which comprises forming a wax mixture consisting essentially of in percent by weight about 10 to 60 of an organic compound additive which is a solid at room temperature and contains a C.dbd.

Abstract: A method is disclosed for producing metal carbide grade powders, which comprises dry milling metal carbide powder which can be tungsten carbide, titanium carbide, tantalum carbide, niobium carbide, vanadium carbide, chromium carbide, and combinations thereof to increase the surface area of the powder particles to result in essetially all of the powders being converted to single crystals, forming a mixture of the resulting dry milled carbide powder, a binder metal which can be cobalt, nickel, and combinations thereof, and a wax, while heating the carbide powder, the binder metal and the wax to a temperature above the melting point of the wax and maintaining the temperature to result in a uniform distribution of the wax on the carbide and binder metal particles, forming a slurry of the mixture and water, attritor milling the slurry at a temperature below the melting point of the wax, and removing the water from the resulting attritor milled mixture and aggiomerating the mixture to produce the metal carbide grad
