  • Patent number: 8920218
    Abstract: An electrode dresser is provided. The electrode dresser includes a face cutting segment having a top surface and a face rake surface. The top surface intersects the face rake surface and forms a face cutting edge. The face cutting edge is configured to remove deposits located on a face of an electrode. The face rake surface forms a face rake angle with a line generally perpendicular to the top surface. A side cutting segment extends from the face cutting segment and has a top surface and a side cutting surface. The top surface intersects the side cutting surface thereby forming a side cutting edge. The side cutting edge is configured to dress a distorted tapered side of an electrode tip. The side cutting surface forms a side rake angle with a line perpendicular to the top surface.

  • Patent number: 8904886
    Abstract: A moveable end (ME) sample cylinder device is provided which employs a method of collection wherein the initial cylinder volume of the collection vessel or sampling cylinder is zero. The sample cylinder is inserted into the pressurized gas (or fluid) source for spot sampling thereof, said sample cylinder employing a piston or moveable end configured such that purging of the cylinder sample cavity is not required, since the sample cavity volume is essentially eliminated prior to sampling by the location of the piston within the cavity, the cavity expanding upon sampling via piston movement within the cavity. Also contemplated is a cap/body (CB) spot sample cylinder having a low internal volume and which can be inserted into a pressurized process through common valving. Insertion of the CB sample cylinder into the process eliminates purging of interconnecting tubing and also eliminates the impact of low ambient temperatures which can otherwise alter the spot sample composition.

  • Patent number: 8904872
    Abstract: The present invention relates to a method of detecting non-linear operation of a measuring device comprising an array of transducers and at least one receiver channel portion. The method comprises receiving measured signals through transducers of the array, processing the measured signals from the transducers through the receiver channel portion, combining the processed measured signals to produce a combined measurement signal, and detecting non-linearity of the combined measurement signal and non-linear operation of the measuring device by detecting saturation of the receiver channel portion. In one embodiment, the receiver channel portion comprises an analog-to-digital converter, a threshold is assigned to a digital output of the analog-to-digital converter, and saturation of the receiver channel portion is detected when the digital output of the analog-to-digital converter oversteps the assigned threshold. In one application of the invention, the measuring device is a non-destructive testing device.

  • Patent number: 8800394
    Abstract: A transportable Sample Apparatus includes a vacuum flask (Dewar flask) and integral sample container. The Sample Apparatus may be used to capture a liquid phase LNG sample at a custody transfer point and to transport the sample to a laboratory for analysis. Vaporization of the liquid phase sample may take place at a variety of different locations. For example, vaporization may begin and/or be completed during transport from the collection point to the laboratory. In another example, vaporization may begin and be completed in the laboratory. In yet another example vaporization may begin during transport and be completed at the laboratory. The gas phase sample is typically analyzed by a gas chromatograph for Btu content, among other things. Prior to capture of the sample, the Sample Apparatus goes through a pre-cool cycle to chill a sample end cap and other components to a temperature compatible with capture of a cryogenic liquid sample which is about ?250° F.
