Patent CA-2211640-A1 (CA)
Title: Method for identifying subsurface fluid migrational pathways using 3-d and 4-d seismic imaging
Inventor: ANDERSON ROGER N
IPC: G01V1/30
Filed: 1996-03-01
Abstract: The invention utilizes 3-D and 4-D seismic surveys as a means of deriving information useful in petroleum exploration and reservoir management. The methods use both single seismic surveys (3-D) and multiple seismic surveys separated in time (4-D) of a region of interest to determine large scale migration pathways within sedimentary basins, and fine scale drainage structure and oil-water-gas regions within individual petroleum producing reservoirs. Such structure is identified using pattern recognition tools which define the regions of interest. The 4-D seismic data sets may be used for data completion for large scale structure where time intervals between surveys do not allow for dynamic evolution. The 4-D seismic data sets also may be used to find variations over time of small scale structure within individual reservoirs which may be used to identify petroleum drainage pathways, oilwater-gas regions and, hence, attractive drilling targets. After spatial orientation, and amplitude and frequency matching of the multiple seismic data sets, High Amplitude Event (HAE) regions consistent with the presence of petroleum are identified using seismic attribute analysis. High Amplitude Regions are grown and interconnected to establish plumbing networks on the large scale and reservoir structure on the small scale. Small scale variations over time between seismic surveys within individual reservoirs are identified and used to identify drainage patterns and bypassed petroleum to be recovered. The location of such drainage patterns and bypassed petroleum may be used to site wells.

Title: Epoxy-based, voc-free soldering flux
Inventor: DIEP-QUANG HIEP
IPC: B23K35/363
Filed: 1996-05-24
Abstract: A resin-based VOC-free soldering flux consists of 40 to 50 wt.% of a liquid epoxy resin, 25 to 30 wt.% of a non-volatile liquid epoxy diluent, 20 to 33 wt.% of a polyfunctional carboxylic acid, and 2.0 to 3.5 wt.% of a thixotropic agent. There are no volatile organic solvents or compounds in the flux which can evaporate during the reflow process. The carboxylic acids are provided in powdered form and are suspended in the epoxy blend wherein they remain as solid particles until heated in the solder reflow process. A VOC-free solder paste formed from the flux consists of 40 to 95 wt.% soldering particles, and 5 to 60 wt.% of the VOC-free soldering flux. The thixotropic agent improves printability of the solder paste onto printed wiring boards. A VOC-free flux-core solder wire includes the VOC-free flux as the inner core of the wire with an outer shell of solder alloy. The VOC-free, epoxy resin based flux effectively activates the solder powder and the copper contact during the reflow process, while at the same time hardens to leave a solid, dry, yet flexible residue on a printed wiring board. No organic compounds are emitted during the reflow process.

Abstract: Methods are disclosed for cutting the pizza to size, bringing the dough piece to the next station, and curling up the edge(s) of the pizza piece.      A dough band, bread or flaky type, of appropriate width and thickness is brought to the cutting and curling apparatus. The first station is made of a special device that cuts to the desired dough size while the dough band is in movement. The dough may vary in thickness and stiffness, the cut dough pieces can be of different shapes and sizes.      The cutting out or trimming is continuously removed and brougth back to the dough preparation system.      The cut dough piece or the pizza of unbaked dough is directed to the edge forming apparatus where the edges) of the « pizza » dough are curled up while in movement.      The curled edge pizzas of different shapes are then ready for the next processing step, freezing or garnishing.      The actual only way known of rolling up the edge(s) of bread or flaky doughs, as of the round pizza whose mechanized process is described hereafter, is the manual way requiring quite a number of persons. The result is that large quality variations are obtained depending on the ability of each individual. The proposed mechanized way of rolling up edge(s) of different dough pieces will allow to achieve a much more regular result with a significant labour reduction.
