Abstract: A multifunction blowout preventer has a housing formed from a single piece of material, which has a central bore, a bottom connection, a gate valve section, an integrated ram assembly/flow tee section, and a top connection. The blowout preventer optionally includes a gas lift/electrical ports section. The components of the blowout preventer are radially offset and/or staggered from one another about the periphery of the housing to help minimize the height of the blowout preventer.

Abstract: An adjustable blowout preventer may be configured to be adjustable, such that a central bore of the blowout preventer may be adjusted or repositioned. The blowout preventer may include one or more adjustment mechanisms for adjusting an angle of tilt of the central bore and/or an offset distance of the central bore. The adjustment mechanisms may be arranged between a stack of the blowout preventer and a wellhead. The adjustment mechanisms may generally be tubular structures having angled and/or laterally offset bores therein. The adjustment mechanisms may be configured to be rotatable, such that rotation of the mechanisms may change an angle of tilt and/or lateral offset of the blowout preventer central bore, or portions thereof.

Abstract: A blowout preventer (BOP) and a seal anti-extrusion apparatus is provided for well control about a tubular such as a polish rod. Each of opposing ram blocks support a semi-circular primary seal and at least one downstream backup ring. An extrusion gap is formed between the ram block and the rod. The backup ring has profile that is axially compressible by the primary seal when activated, causing an inner diameter diminish, and closing the extrusion gap for improved sealing integrity of the primary seal.

Abstract: Apparatus and methodologies are provided for modifying the wellhead structure of a production well to seal the production well before subterranean fracturing operations. The apparatus includes an enclosure tubular and adapter 5 for sealingly engaging the polish rod extending from the wellhead structure, while maintaining the entire rod string in tension in a manner to ensure that the string and its connection with the downhole pump are not compromised. More specifically, the present preparations involve retaining the rod string in tension while removing at least the stuffing box from the wellhead structure, and 10 temporarily installing the enclosure tubular and adapter to seal the wellhead, preventing wellbore blowouts.

Abstract: Methods for treating and/or delaying onset of dysplastic lesions in the bronchial airway of an individual comprise delivering to the respiratory track of the individual an inhalable dry powder composition including an effective amount of myo-inositol.

Abstract: A dual-purpose tool configured both for compacting packing material around a rod, pipe, or axle, such as in a stuffing box, and for extracting such packing material. The tool may have a compaction end configured with a packing ram for compressing packing material into a stuffing box, or otherwise compressing the material around a rod. Additionally, the tool may have an extraction end with one or more tapered cleats configured for driving into compacted packing material to loosen and extract the packing material. The dual-purpose tool may be relatively easy to use, comprising two hand-held components that may be nestably positioned on opposing sides of a rod. Each component of the tool may have an elongated semi-circular shape extending between a compaction end and an extraction end. Each component may further have a handle by which a user may manipulate the component to perform packing and extracting operations.

Abstract: A modified stuffing box for a wellhead is provided. More particularly, a modified stuffing box having improved and adjustable sealing is provided. The modified stuffing box may include a valve for sealing the well.

Abstract: The present disclosure relates to adjustable blowout preventers and methods of adjusting a central bore of a blowout preventer. A blowout preventer of the present disclosure may be configured to be adjustable, such that a central bore of the blowout preventer may be adjusted or repositioned. In particular, a blowout preventer of the present disclosure may have one or more adjustment mechanisms for adjusting an angle of tilt of the central bore and/or an offset distance of the central bore. The adjustment mechanisms may be arranged between a stack of the blowout preventer and a wellhead. The adjustment mechanisms may generally be tubular structures having angled and/or laterally offset bores therein. The adjustment mechanisms may be configured to be rotatable, such that rotation of the mechanisms may change an angle of tilt and/or lateral offset of the blowout preventer central bore, or portions thereof.

Abstract: An aligning apparatus may include a housing configured for arrangement about a reciprocating rod, a bore extending through the housing and having a size configured to allow the reciprocating rod to pass through the bore in a reciprocating and longitudinal motion, and a plurality of rolling elements arranged along the bore and configured to guide the rod through the bore during reciprocation operations, wherein the housing includes a plurality of portions and is configured for lateral removal from the reciprocating rod. A wellhead assembly having an aligning apparatus and/or a pump jack with an aligning apparatus may also be provided.

Abstract: Methods and products for treating and/or delaying onset of dysplastic lesions, and wafers for oral administration employ dry powder compositions including myo-inositol. Methods for administering a vaccine for a virus or bacteria to an individual comprising administering a first portion of the vaccine to the individual via one route and administering a second portion via a second, different route. In a specific embodiment, the first route is sublingually. Vaccines are provided in the form of dry powder compositions comprising a combination of nanoparticles and microparticles, or in the form of a wafer which dissolves in water at room temperature in less than about one minute. Storage stable unit dosages of a vaccine are provided by individually packaging individual unit dosages of a dry powder composition comprising the vaccine and a carrier in blister compartments formed of gas and moisture resistant material.
