Abstract: A chemical vapor deposition apparatus comprises a heating element capable of emitting electromagnetic radiation; a retort positioned relative to the heating element to receive the electromagnetic radiation; an encasing member at least partially disposed around the retort, the encasing member comprising a material that is at least partially transparent to the electromagnetic radiation; a plenum defined at least in part by an inner surface of the encasing member and an outer surface of the retort; and a furnace box at least partially disposed around the encasing member and the retort, and housing the heating element.

Abstract: A power supply unit according to a preferred embodiment of the invention is self testing. The power supply unit is enabled to function with no external loads applied, and includes a visual indicator of whether or not one or more voltage outputs of the power supply unit is within tolerance. To benefit from the self-test feature, a user in the field may simply unplug the power supply unit from all loads, plug the unit into an A/C source, and observe the visual indicator. If the visual indicator is lit, then the user may reasonably assume that the power supply unit is functioning correctly. But if the visual indicator is not lit, then the user may reasonably assume that the power supply unit is faulty.

Abstract: A water-cooled stator bar clip for electrical generators and a method for applying a corrosion-resistant protective coating, preferably Sc, Ti, Cr, Zr, Nb, Mo, Hf, Ta, W, Ni, and Al, and their alloys or oxides to existing stator bar end fittings in order to significantly reduce the possibility of leaks through the brazed connections of the copper stator bar end connections. The coatings can be applied locally using various known physical vapor deposition (“PVD”), chemical vapor deposition (“CVD”) or other direct coating techniques known in the art. For example, the coatings can be applied using ion plasma deposition, sputtering or wire arc techniques (all PVD processes) or by using electroplating, high velocity oxygen free (“HVOF”) deposition, DC arc or electroless plating. Preferably, the coatings are applied either to new stator bar clips or to existing clips in the field.

Abstract: Circuit for generating a spread spectrum clock (CGSSC) that employs a mechanism to modulate the input voltage (V_ctrl) to the VCO to achieve dithering. The CGSSC includes a voltage controller oscillator (VCO) that generates an output signal (F_out). The VCO includes an input coupled to a voltage control node for receiving a voltage signal and an output for generating a clock signal that has a frequency dependent on the received voltage signal. A VCO input voltage modulation mechanism (VIVMM) is coupled to the voltage control node (V_ctrl) for modulating or adjusting the voltage at the VCO input voltage node in a controlled manner to generate a spread spectrum clock.

Abstract: Print systems are provided. A representative print system includes a printing device and a print authorization system. Preferably, the printing device includes a first print cartridge containing a print substance as well as a readable identification tag for providing first information. The printing device also includes an identification reader for receiving the first information. The identification reader enables the printing device to print if the first information corresponds to the printing device. The print authorization system is configured to receive, via a network, information to be printed and second information corresponding to a user. Third information can be received and, if the third information corresponds to the second information, the print authorization system enables the printing device to print the information to be printed. Methods, computer readable media and other systems also are provided.

The method comprising receiving a resource request from a preferred subscriber having a monetary priority designation and processing the job request from the preferred subscriber prior to processing other job requests from non-preferred subscribers having a non-priority designation.

Abstract: No-rinse floor cleaning compositions which provide improved burnish response to finished floors are sold in concentrated form or in diluted, ready to use form. The concentrated compositions when diluted with water comprise from about 100 ppm to about 750 ppm of an amine oxide surfactant, from about 0 ppm to about 650 ppm of a nonionic surfactant, and from about 1 ppm to about 40 ppm of a silicone antifoam agent. These floor cleaning compositions are substantially free of harsh chemicals and are particularly suitable for use on highly polished floors in commercial environments where daily burnishing is most often utilized.
