Abstract: In a method of facilitating flight operations, a payload is coupled to a spacecraft via a payload interface. The relative alignment of the payload and the spacecraft is dynamically adjusted (e.g., for thrust alignment) while the payload remains coupled to the spacecraft.

Abstract: A cognate specification system manages and enforces digital, canonical representations of entities that are added to and in the system by creating a composite entity key (“EntityKey”) that uniquely and immutably identifies each entity within the system, and that is created based upon the attributes of the entity rather than being arbitrarily assigned. Entities may be organized into various types or cognates, each associated with distinct sets of attributes. A physical or digital referent may be added to the system as an entity by specifying attributes. In such a system, any entity, whether a physical or digital referent, a process, or other type, is uniquely and verifiably identifiable, and may be linked to or associated with other entities, allowing users of the system to produce and access specification granularity beyond traditional approaches focused on systems interoperability.

Abstract: An ion generating device can include a housing having an opening, an anode and a cathode disposed within the housing and having a space between them in fluid communication with the opening, a power source having a negative terminal and a positive terminal with a first connection between the negative terminal and the anode and a second connection between the positive terminal and the cathode, and an air mover disposed to direct an air flow through the space and out of the opening.

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.
