US Classification:

419 15

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 grade powder wherein a densified article made therefrom exhibits essentially no pores that are greater than about 10 micrometers in diameter after sintering at from about 1350. degree. C. to about 1540. degree. C.

International Classification:

G03B 21/14
G03B 21/16
G03B 21/20

Abstract:

This system relates to a projection fixture designed to create a rippling effect in a variety of colors. By using an RGBX color mixing technique, a variety of colors can be produced without the need for color filters which detract from the overall brightness of the beam. A passive cooling technique is also used which allows for silent operation of the projection fixture. Ripple effects may be created through the use of glass gobos that have the capabilities to rotate.

Abstract:

A dental light having an array of light emitting diode (LED) assemblies, at least one first LED assembly having at least one first LED element configured to emit light according to a first spectral distribution, a conversion phosphor configured to convert at least a portion of the first spectral distribution. At least one filter is fixed within said converted light, the filter configured to block at least a portion thereof. The array includes at least one second LED element configured to emit light according to a second spectral distribution, wherein light having the filtered spectral distribution is selectively emitted from said array in a first mode and from both the filtered and second spectral distributions in a second mode.
