Title: Method and system for producing natural gas from offshore wells
Inventor: BRESIE DON ALAN
IPC: B63B27/24
Filed: 1984-06-22
Abstract: Transporting pressure vessels are mounted on watercraft 26, and are utilized to recover raw natural gas from shut-in offshore wells. After a discrete batch of raw gas is contained within the transporting pressure vessel, the watercraft is moved to a processing station, also preferably located on a platform offshore. At the processing station, liquids are separated from the natural gas, and then the natural gas is passed through a dehydrator before being transported or transmitted. The invention allows recovery of natural gas from offshore wells, without the need to place processing equipment at each well. A production barge carrying a storage pressure vessel may be positioned at the well site, to which the watercraft are connected for loading raw natural gas. <IMAGE>

Patent GB-866166-A (GB)
Abstract: 866,166. Geophysical prospecting. JERSEY PRODUCTION RESEARCH CO. Feb. 10, 1958 [June 25, 1957], No. 4260/58. Class 40(7) [Also in Group XIX] In apparatus for producing a seismic section from a multi-trace reproducable seismic recording made in the field, corrections for "static" errors (i.e. errors independent of signal travel time and arising, e.g. from the differing elevations of geophones and shot point) and "dynamic" errors (i.e. errors which vary with signal travel time and arising, e.g. from lateral geophone-shot point separations) are incorporated by sensing marks on cards to adjust the relative positions of recording and reproducing heads used in that part of the process intermediate between reading off from the initial field record and final writing of the corrected traces. Drum 12 carries the field record in the form of circumferential parallel traces on a magnetic tape 22 and associated reproducing heads 20 feed sequentially recording head 28 above magnetic tape drum 14. Reproducing head 40 feeds pen recorder 84 above recording paper drum 16. Static error correction is set in by the degree of rotation of arm 30 produced by motor 38 which is stopped when a feeler 44 meets a conductive mark in the appropriate column of a previously-prepared card 41, see also Figs. 2 and 3 (neither shown). The setting of the feeler into the appropriate card column is made by a switch 96 actuated by sequence controller 26. Dynamic error correction is set in by the angular displacement of reproducing head 40, produced by a cord 58 running over pulley 98 and through hook 63 on block 64 to nut 60. Block 64 moves along a lead screw 66 as shaft 18 rotates and nut 60 moves along a lead screw 62 whose rotation is controlled from a card-sensing arrangement similar to the one described above. The cord linkage is so dimensioned that the requisite error correction is afforded, Figs. 4 and 5 (neither shown). Recording pen head 84 is moved either manually along drum 16 by a screw 72 prior to each trace recording, or automatically by a further sensedcard arrangement.

Title: Detection of motion and method of estimating the velocity of a moving object in a sequence of images
Inventor: RICHARD CHRISTIAN
IPC: G06T7/20
Filed: 1987-12-30
Abstract: Each image is swept, sampled and digitised, line by line and point by point, each image point being represented by the value of its luminance. During an image sweep, points, called movement points, whose luminance value is different to that of their equivalent points in a preceding image, called the reference image, with a difference greater than a fixed step, is attributed to a zone each zone regrouping connected points in movement is given a number (Zi). Each zone (Zi) is characterised by the components of a vector E(Zi), called the state vector, which contains the number N(Zi) of points attributed to the zone (Zi). For each zone of the current image (Zi) a search is made to determine if there exists equivalent zones in the zone (Zi) of the preceding current image, from which is deduced a value, called the former value of this zone. It is considered that a point is in true movement, not due to noise, if the zone to which it belongs, contains a number of points greater than a fixed step and if it has a former value greater than a fixed step.
