Abstract: A method of sharing a printer between a plurality of users on a computer network includes attaching host-based networking hardware to the printer. A network communication protocol defines a command channel and a data channel. Only one of the users is allowed to own the data channel at any single point in time. The host-based networking hardware is instructed to accept information on the data channel only from the user that owns the data channel.

Abstract: A novel molybdenum compound, ammonium dodecamolybdomolybdate (AMM), is described which may be used in the manufacture of molybdenum metal and molybdenum carbide powders. The molybdenum compound is a dodecaheteropoly acid salt having a Keggin-type structure wherein molybdenum resides in both the hetero as well as peripheral atomic positions. The novel compound has the general formula (NH4)2Mo12MoO40·6H2O. Because of its low solubility, the compound can be crystallized efficiently and at a high purity from ammonium molybdate solutions.

Abstract: A method for monitoring the composition and flow rate of wastes discharged from industrial waste water treatment facilities into a common collection system for eventual processing at central waste water treatment plant (WWTP). The information is transmitted to a remote computer and stored in a database, and is then analyzed to prepare reports of particular interest to the receiving WWTP or treatment facility. The system includes a data collection and sending unit, a remote Internet Server computer with a database capable of receiving and storing the collected information, and a web server and reporting unit to analyze the data, prepare reports, and send out alarms. It is a further intention of this invention to correlate the incoming data from said industrial waste water treatment plants with known flows and compositions at said central WWTP to predict the flow and composition of influx water at the WWTP.

Abstract: An electrochemical displacement-deposition method for making composite metal powders is described. The method is carried out by combining tungsten or molybdenum metal particles with particles of silver oxide or copper oxide in an aqueous hydroxide solution. Heat is applied to the solution to cause the oxide particles to convert to silver or copper metal particles which are substantially adhered to the refractory metal particles. Unlike conventional methods, it is not necessary to heat the oxide powders to a very high temperature in a reducing atmosphere in order to form the composite metal powder.

Abstract: The present invention provides for Troika acids attached to a macroporous resin and Methods of preparing the same, including direct attachment of a Troika acid, and attachment of a Troika acid precursor followed by generation of the Troika acid in situ. Methods of functionalizing a resin to facilitate attachment are also described. Multiple Troika acids, comprising a pair of Troika acids joined together are described. Synthetic routes to both microporous and macroporous resins modified by introduction of a suitable Troika-type acid have been designed and validated. In a preferred embodiment, a macroporous Troika resin removes Cu2+ and Ni2+ from aqueous solution with high affinity, and is selective against Mg2+ or Ca2+. The materials of the present invention have advantages for metal removal from power plant waste water.

The method includes the steps of defining a network; providing a network adapter communicatively connected to the network, the network adapter connected to the networked device; providing memory in the network adapter; updating information in the memory, wherein the information describes a status of the networked device; placing the information into a response frame; and sending the response frame in response to any command frame received by the network adapter.

Abstract: A system for monitoring water quality at remote locations in a water distribution system using water sensors installed at end user sites to detect contaminants downstream in the distribution system. Each sensor includes an integral processing means and a communications interface allowing the sensor to be coupled to a a remotely located Internet server via telephone lines at the end user site. The sensor assemblies are effective for measuring critical water parameters, processing measured data to provide quantified output data, and transmitting the output data to the Internet server in real time. A processor resident on the Internet server is operable to compare the output data with pre-established safe water parameters, determine differentials between pre-established safe water parameters and the output data, and issue an Alarm Event report if known limits for the differentials are exceeded. The Alarm Event report can be automatically transmitted to Department of Homeland Security.

Abstract: A method and apparatus for increasing the voltage resolution of a PWM controller wherein the controller controls pulse width as a function of a PWM register count having a maximum count X where 1 part in X affords insufficient resolution, the method including receiving a high resolution voltage request count from within the range 0 through count Y where the voltage corresponding to count Y is equal to the voltage corresponding to count X and where count Y is greater than count X, the method including dividing the request signal by a divisor (Y/X) to generate an output value and a remainder, identifying a pseudo-random number within the range of possible remainder values, comparing the pseudo-random number to the remainder, where the pseudo-random number is less than the remainder, incrementing the output value, providing the output value to the PWM register as the register count and repeating the aforementioned steps.

Abstract: Methods and apparatus for using isochronous data transfer mode to communicate between a host computer and a printer. Preferably, the printer receives a sufficient volume of data from the host, such as a computer, over an isochronous communications channel, to begin but not complete one print pass (i.e., line scan or page scan). Subsequently, the print pass is initiated causing a print mechanism to move a printing device relative to a substrate without interruption. Thereafter, sufficient data to complete the pass without interruption is received over the isochronous communications channel during the print pass. The high speed transfer rates afforded by isochronous data transfer allow for printing to be initiated before all of the data necessary to complete a print operation without interruption is received. Moreover, the size of a printer buffer used to store the print data before printing may be considerably reduced to store only a portion of the data needed for an entire print pass.

Abstract: A method for purifying a phosphorus containing scheelite ore is described wherein the calcite phase is selectively dissolved prior to dissolution of the apatite phase. Selective dissolution of the calcite produces several benefits: (1) a usable calcium solution, (2) enhanced apatite dissolution, and (3) lower volumes of toxic acid solution for disposal.

Abstract: A simple, cost effective method for reclaiming tungsten values from tungsten-thoria has been invented. The method involves reacting the tungsten-thoria with molten sodium hydroxide to form a soluble sodium tungstate and an insoluble residue of thoria, cooling the melt, dissolving the melt in water, and filtering to separate the insoluble residue of thoria from the dissolved sodium tungstate. The method resulting in substantially all of the tungsten values being reclaimed as sodium tungstate and acutely reducing the amount of radioactive material for disposal.
