摘要:
An x-ray source assembly (2700) and method of operation are provided having enhanced output stability. The assembly includes an anode (2125) having a source spot upon which electrons (2120) impinge and a control system (2715/2720) for controlling position of the anode source spot relative to an output structure. The control system can maintain the anode source spot location relative to the output structure (2710) notwithstanding a change in one or more operating conditions of the x-ray source assembly. One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.

摘要:
A method and apparatus for analyzing fluids by means of x-ray fluorescence. The method and apparatus are applicable to any fluid, including liquids and gases, having at least one component that emits x-ray fluorescence when exposed to x-rays. The apparatus includes an x-ray source (82) including an x-ray tube (64) having improved heat dissipating properties due to the thermal coupling of the x-ray tube with a thermally-conductive, dielectric material (70, 1150). The x-ray tube also includes means for aligning (100, 2150, 2715) the x-ray tube with the x-ray source housing whereby the orientation of the x-ray beam produced by the x-ray source can be optimized, and stabilized various over operating conditions. The method and apparatus may also include an x-ray detector having a small-area, for example, a PIN-diode type semiconductor x-ray detector (120), that can provide effective x-ray detection at room temperature. One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.
摘要:
A method and device for cooling and electrically-insulating a high-voltage, heat-generating component, for example, an x-ray tube (1105) for analyzing fluids by means of x-ray fluorescence. The device includes an x-ray source (1100) including an x-ray tube (1105) having improved heat-dissipating properties due to the thermal coupling of the x-ray tube with a thermally-conductive, dielectric material (1150). The device may include a base assembly (1135) mounted to the component for conducting heat away from the component while electrically isolating the component. In one aspect of the invention, the base assembly includes two copper plates (1140, 1145) separated by a dielectric plate (1150). The dielectric plate minimizes or prevents the leakage of current through the base assembly (1135). One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.
摘要:
A system and method for the installation and removal of monitoring equipment is disclosed. In some embodiments, the monitoring equipment may be installed or removed using a remotely operated vehicle. In certain implementations, the monitoring system includes a sensor assembly connectable to a tubular member, an alignment tool for installing or removing the sensor assembly to and from the tubular member, and an alignment cage for facilitating access of the alignment tool to the sensor assembly. In some embodiments, the alignment tool may be aligned with the sensor assembly for installation or removal as a result of the alignment tool being inserted through the alignment cage.
摘要:
A system and a method for configuring distributed network content in real time are disclosed. The system comprises a network, a plurality of user terminals and at least fist and second servers, all being connected to the network. The first server stores network content and distributes it according to network requests of remote user terminals. Each user terminal communicates data representative of user interaction with at least a portion of the network content to the second server, at which it is stored. The second server processes the stored data into respective network content-configuring data for each user terminal and the first server distributes next network content to each user terminal according to the respective network content-configuring data received from the at least second server.
摘要:
A method and apparatus for inserting wicks into candles formed in jars or containers characterized by a device comprised of a hollow tube, sealed on one end, in which a wick and wick base can snugly fit, and a crosspiece having width greater than width of the mouth of a jar so that after candle wax is poured, the wick straightening device is inserted into the jar and is removed after the wax has cooled so that the wick will remain straight even after the candle wax has cooled.
摘要:
An asset recovery system and method is provided for recovering value from shipped products that are returned and/or rejected by the purchaser or recipient. The system and method include inspecting the rejected or returned product at a returns center, assessing the cost to repair or refurbish the product. If the assessment is within a predetermined cost structure the product is repaired or refurbished and placed in a saleable item inventory for resale to a customer. If the assessment is outside the predetermined cost structure, the product is liquidated.
摘要:
A cabinet having a plurality of rack mountable chassis. One portion of such chassis has directors and electrically interconnected memory and another portion of such chassis having a plurality of disk drives. The plurality of chassis are electrically interconnected to provide a data storage system interface. The another portion of the cabinets includes therein a printed circuit board having plugged into a surface thereof a plurality of disk drives. The cabinet includes a plurality of rack mountable chassis. A first one of such chassis has a memory and a plurality of directors for controlling data transfer between a host computer/server and a bank of disk drives as such data passes through the memory. A first plurality of the directors are for coupling to the host computer/server. A second plurality of the directors are for coupling to a bank of disk drives. A second one of such chassis has a plurality of disk drives, such disk drives being plugged into a surface of a printed circuit board. Electrical conductors are provided for connecting the disk drives in the second chassis to the second plurality of directors in the first chassis.
摘要:
A fiber channel, interconnecting a plurality of disk drive loops and associated high speed bypass switches, has a selected group of high speed bypass switches to modularize the fiber channel and to reduce electrical signal jitter on the channel. More particularly, the fiber channel loop has a first group of bypass switches being connected to either connect an associated disk drive to the loop or to electrically isolate the loop from the associated disk drive, and a second group of the bypass switches is then connected, in a first operating state, to connect a group of disk drives and their respective associated bypass switches for electrical signal communications with disk drive controller, and in a second operating state, for electrically isolating the group of disk drives and their respective associated bypass switches from communications with the controller. The disk drives and their associated bypass switches can be modularly added to the fiber channel configuration by employing the second group of bypass switches as high speed controllable gateways.
