Title: An alternative method for reducing web feed rate variations induced by parent roll geometry variations
Inventor: BINNER PAUL ALAN SR
IPC: B65H16/00
Filed: 2011-10-25
Abstract: A method is disclosed for reducing feed rate variations when unwinding a web material to transport the web material away from the parent roll at a web takeoff point where the feed rate variations are induced by parent roll geometry variations. The method utilizes both calculated and measured data to make suitable adjustments in the driving speed for an out-of-round parent roll to maintain a relative constant feed rate. By dividing the parent roll into 1, 2,...n sectors, the data can be refined to a relatively high degree taking into account high speed data processing capabilities as well as operating system response times to make appropriate driving speed adjustments.

Title: Areal marine seismic exploration method
Inventor: ILINSKY DMITRY ANATOLYEVICH
IPC: G01V1/38
Filed: 2010-05-21
Abstract: Application: offshore seismic exploration, three-dimensional offshore exploration of oil and gas with wide range of depths, in sea-land transit zones, active and passive monitoring of offshore hydrocarbon reservoirs during its development, offshore sparse three-dimensional surveys, for studying of the earth's crust.  Essence: autonomous self-pop-up multicomponent bottom nodes (self-pop-up nodes SPN) are deployed to the bottom of an exploration area along parallel lines of exploration at specified spaced points by a recording vessel. At least one seismic source mounted on a shooting vessel continuously fires seismic energy. The shooting vessel travels between the SPN deployment lines. The direction of the sailing direction is parallel to the aforesaid lines. A source vessel is initially located at an R distance from the first SPN deployment line, defined as follows:  0,5D <= R <= D, where D is the exploration area width. Every SPN  records seismic waves. Upon the source vessel passes the half of the lines, the recording vessel starts on-going relocation of the deployed SPNs to the next exploration lines starting with the SPNs on the first exploration line. Collection of SPNs is carried out by the recording vessel equipped with a hydro-acoustic communication system with SPNs throughout its ongoing sailing along the SPNs deployment lines.  Thereafter acquired data is processed, which involves extraction of primary reflections and multiples from the recorded signals through summation of vertical component of displacement velocity in the sea bottom with pressure recordings in a water layer, generation of three-dimensional depth and time images of the exploration area from acquired data.
