Patent number: 7719686Abstract: A system utilizing the flow cell of the present invention includes a reflectance mode spectrophotometer positioned with respect to the flow cell or a probe. Either the flow cell or the probe has a thin partition mounted in spaced relationship with respect to a transparent window. The partition has a predetermined index of refraction and has a thickness dimension that is less than that of the window. The spacing between the partition and the window is such that evanescent coupling of radiation reflected from the liquid into the material of the window is prevented. The spectrophotometer directs interrogating radiation toward a liquid flowing through the sample chamber and responds to interrogating radiation reflected from the liquid to produce an electrical signal representative of a color property thereof.Type: GrantFiled: December 5, 2006Date of Patent: May 18, 2010Assignee: E.I. du Pont de Nemours and CompanyInventors: Ken Stephen Schermacher, Jeff B.

Patent number: 7542143Abstract: A flow cell for measuring the color properties of a liquid flowing therethrough using interrogating radiation at a predetermined wavelength has a thin partition mounted in spaced relationship between both a window and a base of the cell. The partition and the window define an air cavity therebetween. The spacing between the partition and the window is such that evanescent coupling of radiation reflected from the liquid into the material of the window is prevented. The cell has a pressurized fluid inflow channel and a pressurized fluid outflow channel formed therein. Each of the inflow and outflow channels communicates with the air cavity. The inflow and outflow channels are sized to pass a pressurized fluid, such as pressurized air, through the air cavity such that, in use, the spaced relationship between the partition and the window is maintained by pressurized fluid in the air cavity.Type: GrantFiled: December 5, 2006Date of Patent: June 2, 2009Assignee: E.I. du Pont de Nemours and CompanyInventors: Thomas W.

Patent number: 7423755Abstract: A flow cell for measuring the color properties of a liquid flowing through the flow cell using interrogating radiation at a predetermined wavelength has a thin partition mounted in spaced relationship between both a window and a base of the cell. The partition has a predetermined index of refraction and has a thickness dimension that is less than that of the window. The spacing between the partition and the window is such that evanescent coupling of radiation reflected from the liquid into the material of the window is prevented. Typically, this spacing is a distance not less than three (3) times the predetermined maximum wavelength in the wavelength range of interrogating radiation. A plurality of spacer elements may be disposed in the air cavity to maintain the spaced relationship between the partition and the window.

Patent number: 6752205Abstract: An improved inflatable packer 10 is provided having a pre-stretched bladder to minimize Z-folding. An expandable outer body 11 includes an inner elastomeric bladder layer 12, a reinforcement layer 14 which may include overlapping slats or cable, and an outer elastomer cover layer 16 which may cover only a portion of the reinforcement layer 14. The bladder 12 may expand non-uniformly due to the variations in the cross-section of the borehole 20, irregularities in construction of the bladder 12, and/or difference in resistance to expansion between the covered portion and the exposed portion of the reinforcement layer 14. An improved inflatable packer and method comprises pre-stretching the bladder 12 to keep the bladder in tension and minimize the occurrence of Z-folds.Type: GrantFiled: April 17, 2002Date of Patent: June 22, 2004Assignee: TAM International, Inc.Inventors: Andrew Kutac, Paul A.

Patent number: 6216779Abstract: An apparatus for orienting a downhole tool relative to a borehole. The invention comprises a phase change material such as a shape memory metal engaged with the tool in an initial position which is activatable to move into an operating position relative to the tool. An actuator activates the phase change material to orient the tool relative to the borehole. The member is engaged with said housing and with the phase change material for selective movement relative to said housing between an initial position and an operating position. The actuator activates said phase change material to move said member. A return spring can move the phase change material to or from the initial position. The invention can be combined with a logging tool or other downhole device to orient the tool within a borehole. In different applications, the invention can center the tool or urge the tool against one side of the borehole wall.Type: GrantFiled: December 17, 1997Date of Patent: April 17, 2001Assignee: Baker Hughes IncorporatedInventor: Paul A. Reinhardt

Patent number: 6062315Abstract: An apparatus and method for transporting a downhole tool in a borehole. A phase change material such as a shape memory metal is activated to engage the borehole and to transport the tool through the borehole. After the tool has been advanced in the borehole, the phase change material is deactivated to release from the borehole wall, and advances into position to continue the transport process. An extension can be engaged with the phase change material to extend the movement range of the phase change material. The phase change material actuator requires few moving parts and can be integrated with other tool components. The invention can operate in opposite directions within a borehole and can replace wellbore tractors and other locomotive tools.Type: GrantFiled: February 6, 1998Date of Patent: May 16, 2000Inventor: Paul A. Reinhardt

Patent number: 5456316Abstract: Actuation of downhole tools is accomplished by inducing motion in the wireline. The downhole tool monitors such motion for predetermined patterns. Detection of a predetermined pattern actuates performance of a desired function. The pattern selected is sufficiently unique to avoid random or premature actuation. The tool may thus be actuated using ordinary nonconducting cable. In like fashion the tool can transmit stored information to the surface by a mechanical means such the resonant frequency of a mechanical signal in the cable.Type: GrantFiled: April 25, 1994Date of Patent: October 10, 1995Assignee: Baker Hughes IncorporatedInventors: Steven C. Owens, Paul A. Reinhardt, Richard Ross

Patent number: 5431412Abstract: The invention comprises a uniquely shaped sealing element or elements for a packer. In an application using a stack of elements, the upper element is configured so that at least a portion of its inside diameter represents an interference fit with the mandrel onto which it is mounted. A built-in moment within the packing element occurs as a result of the partial interference fit. Additionally, a taper is provided which, in effect, shifts the point of contact of the upper element closer to a central element, tending to better give extrusion support to the central element. The taper also facilitates the creation of a resistive moment which fights the tendency of the upper element to extrude in the upper outermost corner of the upper element, for example. The central element can also be installed on a mandrel with interference throughout its length to create a built-in radial force urging the element back into its original shape after it is expanded and allowed to relax.Type: GrantFiled: March 17, 1993Date of Patent: July 11, 1995Assignee: Baker Hughes IncorporatedInventors: Paul A. Reinhardt, William M. Richards, Daniel E. Dinhoble

Patent number: 5425424Abstract: An apparatus and method for producing through a casing without perforation are disclosed. The casing can be rotated while it is cemented and includes a multiplicity of sliding sleeve valves. Each of the valves selectively covers a plurality of pistons, each of which preferably has a rupture disc mounted therein. A pressure-regulating device is provided in association with each rupture disc to ensure retention of sufficient internal pressure in the tubing such that all discs eventually burst without any short circuiting through the discs which ruptured earlier. The outward movement of the pistons acts to assist in fracturing the formation. Thereafter, the pressure used to rupture the discs aids in further channeling the fluid energy of the fluid rupturing the discs, as well as putting additional pressure on the movable pistons to further stress fracture the formation.As the piston is pumped outward, the grease that is held captive within the piston assembly is forced outward through a bladder.Type: GrantFiled: February 28, 1994Date of Patent: June 20, 1995Assignee: Baker Hughes IncorporatedInventors: Paul A. Reinhardt, Douglas J. Murray
