Abstract: Embodiments of the present invention relate to a volumetric compensating annular bellows used to compensate two fluid volumes by an annular displacement. This is achieved using a bellows welded on to a tube with a varying shape radius. A bellows is arranged within the annulus and is deformable in an annular direction in response to fluid volume expansion. The bellows can be used in several oilfield applications for fluid compensation.

Abstract: There is disclosed a contact pin assembly for a high voltage electrical connection, the contact pin assembly comprising: an electrically-conductive outer member which is supportable from a support member, the outer member having a bore extending therethrough, the bore defining a smooth inner face of the outer member and being divergent towards opposite ends of the outer member; a contact pin, ends of which are arranged to be connected directly or indirectly to cables, the contact pin extending through the bore and having a profiled portion which defines a smooth outer face of the contact pin and which is divergent towards opposite ends of the contact pin, the contact pin being concentric with the bore; an electrically-conductive layer provided adjacent the inner face, the electrically-conductive layer being in electrical communication with the outer member and conforming with the profile of the inner face; an annular space between the profiled portion and the electrically-conductive layer; electrical insul

Abstract: In an optical supply arrangement, a laser source (10) provides transmitted laser light down an optical supply line (12, 14). A first coupler (16), remote from the laser source (10) along the optical supply line (14), taps off a small proportion of the transmitted laser light to be returned along the optical supply line (14) to a photo detector (26) driving a monitor (28) and a controller (30). If the monitor (28) detects that the photo detector (26) is experiencing a loss of return laser light, possibly due to a break in the optical supply line (14), the monitor (28) causes the controller (30) to extinguish the laser source (10) in less time than escaping laser light can cause damage to property, person or eyesight. A first embodiment has the transmitted light on a transmission fiber optic (12) and the return laser light on a separate return fiber optic (24). A second embodiment has the return laser light being sent back down the transmission fiber optic (12).

Abstract: A heating and distributed-temperature-sensor cable permanently fixed in a wellbore that permits known amounts of heat to be introduced to subsurface formations and improved temperature measurement thereof. The heat is introduced into a target zone of the wellbore by forming the cable in two sections: an upper section that carries an electrical current without generating significant amounts of heat, and a lower section that generates heat from the electrical current. Continuous distributed-temperature-sensing is performed through measuring various scattering mechanism in optical fibers that run the length of the cable.

Abstract: Precursor for ruthenium film deposition, comprising ruthenium tetroxide dissolved in at least one non-flammable solvent, preferably a fluorinated solvent having the general formula CxHyFzOtNu wherein: 2x+2?y+z and 2?x?15 and z>y and t+u?1 (t+u preferably equal to 1) x, y, and z being positive integers equal to or greater than 1, t and u being integers greater than or equal to zero.

Abstract: A source liquid supply apparatus and method that avoids leaving source liquid-and/or cleaning fluid-derived residues in the vicinity of the connection region between the source liquid feed conduit and the source tank. A flow-switching mechanism is attached to the source tank of a source liquid supply apparatus. This flow-switching mechanism has a first port connected to the discharge port conduit of the source tank, a second port connected to a feed conduit, and a third port connected to an exhaust conduit. The first port can be closed by a valve member on a diaphragm disposed within a common compartment while communication is maintained between the second and third ports. A cleaning fluid source and a purge gas source are connected to the feed conduit. Purge gas and cleaning fluid fed into the feed conduit are discharged from the second and third ports and through the exhaust conduit.

Abstract: This disclosure discusses cleaning of semiconductor wafers after the Chemical-Mechanical Planarization (CMP) of the wafer during the manufacturing of semiconductor devices. Disclosed is an alkaline chemistry for the post-CMP cleaning of wafers containing metal, particularly copper, interconnects. Residual slurry particles, particularly copper or other metal particles, are removed from the wafer surface without significantly etching the metal, leaving deposits on the surface, or imparting significant contamination to the wafer while also protecting the metal from oxidation and corrosion. Additionally, at least one strong chelating agent is present to complex metal ions in solution, facilitating the removal of metal from the dielectric and preventing re-deposition onto the wafer.

Abstract: Integral blocks, chemical delivery systems and methods for delivering an ultrapure chemical to a point of use or to another integral block are provided. More particularly, the integral blocks include a recharge container block, a pressurization gas block, a purge gas block, a waste recovery block, a vacuum block, a solvent supply block, a degas block, a control block, and a filtration block. Various integral blocks may be selected to form a chemical delivery system, which is particularly suited for a given application. A chemical delivery system will typically comprise a chemical container block, a chemical delivery block, and a point of use in line with the chemical container block and chemical delivery block, as well as one or more integral blocks.

Abstract: A method for determining the operating parameters of a system for cooling articles. The temperature of the articles, as they leave a chamber, is predicted. The prediction is made on the basis of operating parameters of the chamber, thermodynamic and physical characteristics of the chamber, and thermodynamic and physical characteristics of the articles. The method may be used to determine the operating parameters for food freezing tunnels.

Abstract: Methods of film deposition using metals and metal oxides. A thin film of germanium oxide and an oxide of a non-germanium metal is deposited by ALD by alternating deposition of first and second precursor compounds, wherein the first precursor compound includes a metal other than germanium, and the second precursor compound includes germanium.

Abstract: A method of manufacturing a gas mixture of at least two components. Oxygen, nitrogen, helium, carbon dioxide, nitrous oxide, and carbon monoxide are all suitable for use as components in this method. Defined amounts of the components are dynamically mixed in order to obtain a first gas mixture at a first pressure less than 200 bar. The first gas mixture contains an intermediate amount of the second component which is less than the amount desired in the final gas mixture. A first component is then added to the first gas mixture to concomitantly dilute the second component. The addition of the first component is stopped when the pressure of the diluted gas mixture reaches a second pressure greater than both the first pressure and 170 bar, and when the diluted gas mixture contains the desired final proportion of the second component.

Abstract: An installation to provide data concerning an object. An electronic label, which includes data storage, is fixed on the object. The installation is capable of reading least part of the data stored by the label and is also capable of accessing a database which contains data concerning the object. The database is associated with an address in that database locating information is stored in the electronic label. The database is accessed on the basis of this locating data, which may be read by a reader. The installation may be used for marking and tracing gas packages.
