Patent CA-2229329-A1 (CA)
Inventor: SHIELLS GORDON MALCOLM
IPC: E21B47/022
Filed: 1996-09-10
Abstract: A borehole survey is conducted at a drilling site (S) by a so-called Interpolated In-Field Referencing (IIFR) method in which: (a) absolute local geomagnetic field data is obtained by spot measurement of the earth's magnetic field at a local measurement site (R) which is sufficiently close to the drilling site (S) that the measurement data is indicative of the earth's magnetic field at the drilling site (S) but which is sufficiently remote from the drilling site (S) that the measurement data is unaffected by magnetic interference from the drilling site and other man-made installations; (b) time-varying geomagnetic field data is obtained by combining the absolute local geomagnetic field data with data indicative of variation of the geomagnetic field with respect to time obtained by monitoring variation of the earth's magnetic field with respect to time at a remote monitoring site (P1, P2); (c) downhole magnetic field data is obtained by monitoring by means of a surveying instrument the magnetic field in the vicinity of the borehole at a series of locations along the borehole; and (d) the orientation of the borehole is determined from the downhole magnetic field data and the time-varying geomagnetic field data. Such a survey method takes into account short-term variations in the geomagnetic field caused by electrical currents in the ionosphere and is therefore more accurate than known survey methods.

Title: Curvature-reduction annealing of amorphous metal alloy ribbon
Inventor: SPECIALE LARRY
IPC: G01V15/00
Filed: 1996-10-01
Abstract: A longitudinal curvature in an amorphous metal alloy ribbon (32) is reduced by heat-treatment. While the heat-treatment occurs, the alloy ribbon (32) is bent "backwards" against the longitudinal curvature, to reduce the amount of heattreatment required. The process is carried out continuously by transporting the alloy ribbon (32) from reel (36) to reel (38), while wrapping the ribbon (32) around a heated roller (34). Using a discrete strip cut from the alloy ribbon (32) subjected to the curvature-reducing process, a magnetomechanical EAS marker (24') is constructed that has a relatively low profile, while retaining desired magnetic properties.

Inventor: SHUMATE JOHN
IPC: H04N5/21
Filed: 1998-04-30
Abstract: A current pixel of a video image is adaptively filtered to provide stronger filtering when there is a high likelihood that noise is present. Weaker filtering is provided when the presence of a color and/or brightness edge is likely in the video image. Each pixel has luminance and chrominance amplitude values. In a filtering method, a current pixel is intermediate to first and second pixels in the video frame. Difference signals are determined based on the amplitude difference between the current pixel and first and second adjacent pixels. A plurality of available filters provide successively stronger filtering of the current pixel amplitude. One of the filters is selected for filtering the current pixel according to the difference signals. Secondary difference signals which indicate the amplitude difference between the current pixel and pixels which are adjacent to the first and second pixels are also considered in the selection process. The selection process may further be biased by a user-selectable control word. The scheme may also provide temporal filtering with successive video frames or images. Filtering with pixel interpolation may also be used.

Abstract: In a method and device for quantizing a spectrum vector, supplied at recurrent time intervals, to produce a spectrum index, a spectrum-vector quantization codebook including a first voice-signal quantization codebook portion and a second non-voice signal quantization codebook portion is used. Whether the spectrum vector represents a voice signal or a non-voice signal is detected. When the spectrum vector represents a voice signal, the first codebook portion is searched for quantizing the spectrum vector and producing the spectrum index. The second codebook portion is searched for quantizing the spectrum vector and producing the spectrum index when the spectrum vector represents a non-voice signal. According to a first alternative, the first and second codebook portions are searched by measuring a weighted distance between the spectrum vector and the entries of these two codebook portions, and the spectrum vector is considered as representing a non-voice signal when the smallest weighted distance is the weighted distance measured between the spectrum vector and one entry of the second codebook portion. According to a second alternative, a weighted distance is measured between the spectrum vector and the entries of the second codebook portion, and the spectrum vector is considered as representing a non-voice signal when the weighted distance measured between the spectrum vector and one entry of the second codebook portion is smaller than a predetermined threshold.

Abstract: A process for the selective removal and recovery of sulfur dioxide from effluent gases is disclosed. The sulfur dioxide is recovered in a sulfur dioxide absorption/desorption cycle which utilizes a liquid solvent to selectively absorb sulfur dioxide from the effluent gas. The liquid solvent comprises an organic phosphorous compound selected from phosphate triesters, phosphonate diesters, phosphinate monoesters and mixtures thereof. Preferably, the liquid solvent comprises phosphonate diesters of formula (I) wherein R1, R2 and R3 are independently aryl or C1 to C8 alkyl. The organic phosphonate diesters are substantially water immiscible, the solubility of water in the organic phosphonate diester being less than about 10 weight percent at 25 ~C, and have a vapor pressure less than about 1 Pa at 50 ~C. In accordance with a preferred embodiment, the liquid solvent comprises dibutyl butyl phosphonate. The absorbed sulfur dioxide is subsequently stripped to regenerate the organic phosphorous solvent and produce a gas enriched in sulfur dioxide content. The sulfur dioxide-enriched gas may be used as part of the feed gas to a contact sulfuric acid plant or a Claus plant for the preparation of elemental sulfur or be cooled to condense sulfur dioxide in the form of a liquid product. The present invention is particularly useful in producing a sulfur dioxideenriched gas from gases relatively weak in sulfur dioxide content.
