Abstract:
Ambidextrous bolts that allow a user to quickly and easily change the side of the firearm from which a spent casing is ejected by application of a simple switching mechanism that does not require disassembly of the firearm. Aspects of the disclosure also include debris shields for improving the longevity and reliability of extractors, firearms that are configured for ambidextrous operation, methods of using firearms, and methods of modifying firearms to incorporate ambidextrous functionality.
Abstract:
This invention concerns a transformer radiator. The radiator includes an inlet manifold, an outlet manifold and a heat exchange fin. The find extends between and is connected to the inlet and outlet manifolds. The heat exchange fin defines at least one oil flow passage to convey transformer oil, which, in use, enters the radiator through the inlet manifold, to the outlet manifold. The heat exchange fin is further provided by a single component having a continuously undulating profile and the manifolds extend transversely to the turns of the undulating profile.
Abstract:
The present invention relates to pharmaceutical compositions for rectal administration comprising fidaxomicin and to a process for preparing the pharmaceutical compositions for rectal administration. The invention also relates to an aerosol canister comprising a foamable pharmaceutical composition comprising fidaxomicin for rectal administration and to the treatment or maintenance of remission of infections such as diarrhoea caused by Clostridium difficile ..
Abstract:
The present invention relates to a pharmaceutical composition comprising arformoterol and fluticasone furoate (preferably for once daily administration), to a process for preparing such a composition and to the use of such a composition for the treatment treatment and/or prevention of respiratory, inflammatory or obstructive airway disease.
Abstract:
The present invention includes methods and compositions relating to the setting of fluids or slurries in a wellbore. In one embodiment, a method of isolating a portion a wellbore includes preparing a sealant composition having a fluid component, a polymeric additive constituent, and a set modifier component. The sealant composition is placed into a wellbore and subjected to ionizing radiation. The ionizing radiation can cause bonding between polymeric additive constituents and create a polymer matrix within the sealant composition that increases the mechanical strength of the sealant composition. The ionizing radiation also alters the set modifier component, triggering the thickening of the sealant composition.

Abstract:
The present invention relates to methods and compositions for treating a water- and hydrocarbon-producing subterranean formation with a relative permeability modifier, and more specifically, to improved treatment fluids, methods for preparing treatment fluids, and methods for use thereof in a subterranean formation. Methods of the present invention comprise providing a treatment fluid comprising a relative permeability modifier, at least one surfactant, and an aqueous phase base fluid; and placing the treatment fluid in a subterranean formation. The relative permeability modifier comprises a hydrophobically modified hydrophilic polymer. The at least one surfactant is operable to maintain the relative permeability modifier in a dissolved state in the treatment fluid above a pH of about 8. The at least one surfactant may be an anionic curfactant.
Abstract:
The present invention describes a process for the preparation of monofluoromethylated organic biologically active compounds using monofluoromethylated reagents. Fluticasone Propionate and Fluticasone Furoate can be prepared using, for example, S-monofluoromethyl-S-phenyl-2,3,4,5- tetramethylphenylsulfonium tetrafluoroborate as monofluoromethylating reagent instead of bromofluoromethane.
Abstract:
A method of servicing a subterranean formation with a servicing fluid, the method comprising providing a first component of the servicing fluid to a first high-pressure pump (50A) at a first pressure, providing a second component of the servicing fluid to a second high-pressure pump (50B) at a second pressure, increasing the pressure of the first component of the servicing fluid at the first high-pressure pump to a third pressure, wherein the third pressure is greater than the first pressure, increasing the pressure of the second component of the servicing fluid at the second high-pressure pump to a fourth pressure, wherein the fourth pressure is greater than the second pressure, communicating the first component of the servicing fluid to a high-pressure manifold (300), communicating the second component of the servicing fluid to the high-pressure manifold, communicating the first component of the servicing fluid from a first high-pressure manifold outlet to a wellhead (60) located at a wellbore, communicating the second component of the servicing fluid from a second high-pressure manifold outlet to the wellhead, and mixing the first component of the servicing fluid and the second component of the servicing fluid at the wellhead to form the servicing fluid.
