摘要:
A wear-resistant flash tank pressure let down nozzle for use in passing an ore slurry into an ore slurry flash tank to release steam from the slurry and reduce the pressure of the slurry. The nozzle has an expansion cone flaring toward the discharge end of the nozzle. The cross-sectional area of a choke section of the nozzle and the exit diameter of the expansion cone are selected to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that underflashing, overflashing, and shock waves inside the flash tank are minimized.

The present invention features a packaging system for two-dimensional optoelectronic arrays. In one embodiment, the packaging includes a heat spreader, a housing with embedded electrical interconnections, a substrate including electrical contacts, an application specific integrated circuit (ASIC) including a hybridized array with vertical cavity surface emitting laser (VCSEL), detectors or both. The waveguide assembly includes a plurality of individual one-dimensional waveguides formed in waveguide sheets, wherein the waveguides match the array footprint on one end and a connector footprint on the other end.

An integrated position and direction system is disclosed that includes a digital compass, wherein the digital compass includes at least three sensors, and a satellite positioning system having a receiver adapted to receive satellite position determining signals. Direction is determined using the digital compass and heading is determined using the SATPOS. When the integrated position and direction system is moving, heading is indicated. When the integrated position and direction system is not moving direction is indicated. The integrated position and direction system automatically switches between the display of heading (when the integrated position and direction system is moving) and the display of direction (when the integrated position and direction system is not moving).

A cement composition for use in acidic environments containing an acid resistant particulate aggregate of fused mullite aggregate or other aggregate material, with quartz, and microsilica in combination with a colloidal silica sol binder and being substantially free of Na compounds and K compounds which react in the presence of sulfuric acid to form alkali sulfates in service, thus reducing the durability or the service life.
摘要:
A drain pan is provided for removing copper ions from condensate water produced by a heating, ventilation and air conditioning unit. The pan defines a volume having two closed ends and an open top so that water can evaporate from the pan. At least one copper removing agent is placed in the pan, and a baffle is provided between the ends of the pan, for routing water entering the pan at one end through the removing agent en route to an outlet at the other end. The removing agent may include mossy zinc and/or activated charcoal.

The present invention provides methods and apparatus for improved error detection in a data processing system. The techniques of the present invention insure that there is a high probability that an error in a record of data (each record comprising a plurality of data bits) is detected. In the event of an error, the present invention applies a randomizing function to the error which modifies subsequent bits within the record and then propagates and further randomizes the error throughout the record to magnify its apparent size. The randomizing and propagation of the error significantly lowers the misdetection probability for random errors within a record, in that error detectability is no longer pattern sensitive. The use of both propagation and randomization functions significantly alters the data containing an error, such that a high probability of detection using check-sum techniques exists.

A multi-output dual polarity inductive boost converter includes an inductor, a first output node, a second output node, and a switching network, the switching network configured to provide the following modes of circuit operation: a first mode where the positive electrode of the inductor is connected to an input voltage and the negative electrode of the inductor is connected to ground; 2) a second mode the negative electrode of the inductor is connected to ground and the positive electrode of the inductor is connected in sequence to one or more of the fourth and fifth output nodes; and 3) a third mode where the positive electrode of the inductor is connected to the input voltage and the negative electrode of the inductor is connected in sequence to one or more of the first, second and third output nodes.
摘要:
A client transmits one or more lead records to a lead enhancement module that is configured to enhance the received lead records and return enhanced lead records to the client. The lead enhancement module may return a contactability score for each lead record, indicating a likelihood that the individual identified in the lead may be contacted using the contact information provided in the lead record and/or additional contract information located by the lead enhancement module. The lead enhancement module may also receive additional data items associated with leads from one or more data sources. Additionally, statistical models that may be customized for each client may be applied to information associated with lead records in order to determine one or more propensity scores for each of the lead records, where a propensity score indicates a likelihood that an individual will take a particular action, such as purchasing particular goods or services.
