Appl. No.:

12/240234

Inventors:

Scott Christopher Jackson - Wilmington DE, US
Peter A. Morken - Wilmington DE, US
George David Robinson - Matthews NC, US
Elliott Echt - Wilmington DE, US

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

E21B 43/22

US Classification:

1662701, 166275, 166300

Abstract:

The present invention provides a method for recovering oil from a subterranean reservoir using waterflooding, wherein the flooding fluid used in the waterflooding process comprises water and one or more ionic polyvinyl alcohol copolymers. The use of one or more ionic polyvinyl alcohol copolymers is expected to increase the recovery of oil by improving both the oil/water mobility ratio and the sweep efficiency in reservoirs with a high degree of heterogeneity.

Appl. No.:

8/444591

Inventors:

Richard A. Hayes - Wilmington DE
George D. Robinson - Matthews NC

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

B05D 302
B05D 304
B05D 310

US Classification:

427341

Abstract:

Compositions based on blends of certain specified poly(vinyl alcohol) copolymers and other poly(vinyl alcohol) polymers are described which are useful as sizes, and have improved ability to be desized from fabrics compared with the other poly(vinyl alcohol) polymers alone. The specific poly(vinyl alcohol) copolymers useful in the blends with other poly(vinyl alcohol) polymers are copolymers having a high level of acrylic ester comonomer. The blend sizes are useful in producing woven materials since they are excellent sizes, and are uniquely adaptable to caustic desizing.

Appl. No.:

8/174861

Inventors:

Lothar S. Jeromin - Newark DE
George D. Robinson - Sewell NJ

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

G01N 2304
G01T 124
H01L 31115

US Classification:

25037009

Abstract:

A large area X-ray image capture element is fabricated by juxtaposing a plurality of discrete array modules in an assembly over the top surface of a base plate, such that each module is disposed adjacent at least one other module to form a two-dimensional mosaic of modules. Each of the discrete modules includes a plurality of thin-form transistors arrayed adjacent the top surface of a dielectric substrate wherein at least one precision-ground edge forms a precise abutment with a precision-ground edge of another substrate. A continuous radiation detecting layer is disposed over the plurality of juxtaposed modules, and produces a latent radiographic image in the form of electrical charges. Such a method minimizes or totally voids the non-radiation-detecting areas created at the borders between the array modules.

Assignee:

Direct Radiography Corp. - Newark DE

International Classification:

H01L 2714

US Classification:

438 73

Abstract:

A large imaging panel useful for direct radiography is prepared from two or four discrete modules, or tiles, containing arrays of solid state pixels. In preparing the large panels, a protective layer is applied over the array of solid state pixels on each module to protect the modules during subsequent processing steps. One or two edges of each protected module is trimmed and polished to form a polished edge which is within a specified distance from the solid state pixels of the array. The polished edges typically are surface treated (e. g. , by etching) to enhance wetting and adherence of applied adhesive material. Protected modules are then assembled on a flat surface to form a two-dimensional mosaic of the modules in a way that each polished edge of each module is placed adjacent to the polished edge of a neighboring module to form a gap and a precise separation between the pixels of neighboring modules which is the same as the separation between adjacent pixels of one of the modules. A curable polymeric material is applied to each gap and cured so that each gap is at least partially filled. A base plate is adhered to the mosaic by means of a curable adhesive layer which is cured.

Assignee:

Direct Radiography, Corp. - Newark DE

International Classification:

H01L 25065

US Classification:

25037009

Abstract:

A method for forming a large imaging panel by assembling a plurality of smaller submodules, the method comprising providing an adhesive filler between two abutting edges of a first and a second submodule, and forming a degassing channel in the adhesive filler extending along the length of the abutting edges. The method may further comprise adhering the submodules onto a top surface of a base plate, beveling the abutting edges of the submodules, and forming the degassing channel in the space between the beveled edges and the base plate. The method may produce an X-ray image capture panel comprising a base plate; a plurality of discrete array submodules juxtaposed over the base plate, each adjacent to at least one other submodule to form a two-dimensional mosaic of submodules having seams therebetween, each seam being filled with filler material and a vented channel in the seam adjacent to the top surface of the base plate; and a continuous radiation detecting layer disposed over the plurality of array submodules.
