Abstract: A method of fabricating a refractory metal ceramic matrix interpenetrating phase harsh environment capable composite is provided. The method includes forming a reinforcing phase by additive manufacturing and introducing a matrix material to the reinforcing phase. The step of introducing the matrix material may be performed by additive manufacturing or a densification process. The reinforcing phase may be a lattice formed of metal or a ceramic, and the matrix material may be a ceramic or a metal. Alternatively, the reinforcing phase formed by additive manufacturing is a laminate layer, and the matrix material introduced to the reinforcing phase is a laminate layer deposited on the reinforcing phase by additive manufacturing in a plurality of alternating layers. A refractory metal ceramic matrix composite is also disclosed. The refractory metal ceramic matrix composite includes a lattice formed by additive manufacturing, and a matrix material deposited in the lattice.

Abstract: A tool interchange for a submersible remote operated vehicle (ROV) arm includes a first interchange body that affixes to an ROV arm. A second interchange body is carried by the first interchange body to rotate on a rotation axis. The second interchange body includes a tool mount actuable between gripping an ROV tool to the second interchange body and releasing the ROV tool from the second interchange body. An inductive power coupling part is provided in the tool mount. The inductive power coupling part is presented outwardly in the tool mount opposite the first interchange body, resides on the rotation axis and is fixed with respect to the first interchange body while the second interchange body rotates. The inductive power coupling part is adapted to inductively communicate power with a corresponding inductor power coupling part of the ROV tool when the ROV tool is docked in the tool mount.

Abstract: A nasal cannula system for use in ventilator systems, particularly continuous positive airway pressure (CPAP) systems. The nasal cannula system has a nasal body with nare prongs that extend into a patient's nostrils when worn. The ventilator system includes a ventilator on an inhalation side and either a bubble chamber or a variable resistance valve on the exhalation side. The inhalation side may include a heater/humidifier in-line with the supply tube so as to treat the air before application. The airway tube may have a generally semi-circular cross-section so as to provide a flat exterior surface for abutment or contact with a patient's skin.

Abstract: A nasal cannula system having nasal prongs with an ancillary delivery system for a treatment fluid into a patient wearing the nasal cannula without removing the cannula. The nasal prongs have parallel ports that fluidly connect the delivery system to the nasal ports on the nasal prongs. The delivery system provides the treatment fluid in an aerosolized form. This configuration combines the aerosolized treatment fluid with the air or other fluid ordinarily delivered by the nasal cannula. The system may also use airway tubes having a generally semi-circular cross-section with an internal rib extending the length of the tube. The semi-circular cross-section provides a flat exterior surface for abutment or contact with a patient's skin and the rib prevents pinching closure of the airway tube.

Abstract: A method of treating a subterranean formation penetrated by a well-bore, for example to facilitate fracturing of the formation, comprises the steps of: (i) selecting a treatment fluid comprising a diverting agent (A) in a flaked form, for example guar gum in a flaked form. (ii) introducing the treatment fluid into the subterranean formation via the well-bore to plug a region of the formation. Thereafter, the formation may be fractured or re-fractured.

Abstract: A method of forming a can end shell is provided which includes providing a can end shell having a central panel portion, a first panel radius around the central panel portion, a chamfer extending from the first panel radius, and a second panel radius around the chamfer, coining the can end shell to form a coined section in the first panel radius around at least a portion of the circumference of the central panel portion, and reforming the can end shell to form a step in the chamfer.

Abstract: A gas supply tube for use in medical settings for the supply of gas to a patient. The airway tube has a generally semi-circular cross-section so as to provide a flat exterior surface for abutment or contact with a patient's skin. A nasal cannula system is constructed using the gas supply tube has a nasal body with cannula configured for insertion into nasal openings of a patient. The nasal body is connected to one or more gas supply or airway tubes. Both the nasal body and the airway tubes have a semi-circular cross-section. The other end of the airway tube(s) is connected to one or more supply adapters having ports matching the semi-circular cross-section. A surface retainer with a clamp having a semi-circular cross-section may adhere the airway tube to a patient's skin.

Abstract: A tab is provided, which includes a body having first and second opposing ends, a nose portion disposed at or about the first end of the body, a lift portion disposed at or about the second end of the body of the tab, and a rivet receiving portion disposed proximate the nose portion. The rivet receiving portion includes a generally planar portion, a rivet hole having a perimeter, and an upturned portion extending upwardly from the generally planar portion about the perimeter of the rivet hole. The upturned portion reinforces the rivet hole and has an arcuate cross section profile. An integral rivet extends through the rivet hole and is staked to affix the tab to a can end. The upturned portion is devoid of any corners or edges both before and after the integral rivet is staked.

Abstract: A method of forming a can end shell is provided which includes providing a can end shell having a central panel portion, a first panel radius around the central panel portion, a chamfer extending from the first panel radius, and a second panel radius around the chamfer, coining the can end shell to form a coined section in the first panel radius around at least a portion of the circumference of the central panel portion, and reforming the can end shell to form a step in the chamfer.

Abstract: A tab is provided to facilitate opening of a can end. The tab has a nose portion located at a first end of the tab and a lift portion located at a second end of the tab opposite the nose portion. A rivet receiving portion is located proximate to the nose portion, and includes a rivet hole. A flange extends rearwardly from the lift portion of the tab to define a gap. The gap provides increased space between the underside of the flange and the exterior of the container end, thereby facilitating opening of the container end.

Abstract: When a buyer's debt to a seller cannot be paid using an account issued to the buyer by an issuer within a payment processing system, then either or both the seller and the buyer are solicited to conduct future transactions payable on the account. If the debt can be paid using the account, then a sub-account is created unique to the seller and buyer. Transactions between the buyer and seller can be processed using the sub-account including the option of aggregating the debts prior to the processing. The credit limit of the sub-account can be set to match the amount of the aggregated debts.

Abstract: Emulsified acids have been used to increase production rates of oil and gas in carbonate reservoirs through acid fracturing and matrix acidizing operations. An emulsifier is used to emulsify the aqueous acid with an oil, usually diesel. Very small particles, such as colloidal clay particles and/or nanoparticles increase the stability of the emulsified acids over an elevated temperature range.
