摘要： A gas turbine engine assembly is connected to a pylon for mounting the gas turbine engine to an aircraft. The assembly has a frame supporting at least one accessory independently of the gas turbine engine. Frame is attached to the pylon at forward and rearward engine mounting locations. The frame includes at least one hollow tube and at least one hollow tube is fluid tight. The one hollow tube is evacuated or contains pressurised fluid and a pressure sensor is provided to detect a change in pressure in the at least one hollow tube to determine if there is a leak in the at least one hollow tube and hence if the frame is damaged. This ensures that the frame may be repaired or replaced before there is a loss of operation of one or more of the accessories which may result in a failure of the gas turbine engine.

摘要： An adsorption characteristic measuring apparatus is configured to: acquire a unit-time leak pressure value from a pressure increase value of an internal pressure value of a sample tube caused by an non-adsorption gas leaking from the outside of a fitting portion into an inner space of the sample tube; acquire a pressure value at which a temporal change of the internal pressure value of the sample tube assumes an equilibrium state when an adsorption gas present in the reference volume portion is supplied into the sample tube and the sample tube is in a closed state; calculate a pressure value after correction of a real leak pressure value is performed on a measured equilibrium pressure value, as a true equilibrium pressure value, the real leak pressure value being obtained in such a manner that the unit-time leak pressure value is multiplied by a leak time; and calculate an adsorption isotherm.

摘要： The present invention provides a medical device having an elongate body with both a proximal end and a distal end, wherein the elongate body defines an intake lumen and an exhaust lumen. The medical device also has a first pliable element defining a cooling chamber disposed at a point along the elongate body, with the cooling chamber being in fluid communication with the intake lumen and the exhaust lumen. A second pliable element is provided which at least partially encloses the first pliable element, thereby defining a junction between the first and second pliable element. A check valve is included which is in fluid communication with the junction between the first pliable element and second pliable element, the valve further being in fluid communication with the exhaust lumen. Additionally, the medical device may include sensors or other monitoring means in fluid communication with the junction and the cooling chamber.

摘要： Various aspects of the present invention provide a testing apparatus and methods for testing a bellows of a sputter machine for air leakage. One such testing apparatus is configured to simulate conditions of the sputter machine and thereby test a bellows for air leakage in both a compressed and an uncompressed configuration. Accordingly, a bellows can be ensured to be in satisfactory working condition before it is installed in the gate valve assembly and also tested for air leakage after removal from the gate valve assembly.

摘要： Systems, devices, and methods for leak testing surgical conduit grafts or valved conduits such as aortic-valved conduits with a pressurized gas such as air. Air is non-destructive and especially useful for leak testing conduits that have coatings or sealants that may be functionally impacted when exposed to fluids such as water or saline. Open ends of the conduit are clamped and sealed, and a pressurized gas introduced into an inner lumen thereof. A change in mass flow rate is measured to quantify the leakage. One end of a tubular conduit may be clamped to a fixed manifold, and the opposite end to a manifold slidably mounted to accommodate any conduit elongation when pressurized. The clamping and sealing structure may be pneumatic and/or mechanical, and complementary contoured clamp members may be used to seal a scalloped external sealing ring of an aortic conduit.
