Abstract:

An ultrasonic probe for inspecting the interface between the walls of a double-wall tube comprises a cylindrical body member having two cavities axially spaced apart thereon. The probe is placed in the tube and ultrasonic energy is transmitted from a transducer in its body member to a reflector in one of its cavities and thence into the inner wall of the tube. A second transducer in the probe body member communicates with the second cavity through a collimation passage in the body member, and the amount of ultrasonic energy reflected from the interface between the walls of the tube to a second reflector through the collimation passage to the second transducer depends upon the characteristics of said interface.

International Classification:

A62C 3122

US Classification:

169 70

Abstract:

This invention relates to an apparatus and method for penetrating a titanium walled enclosure to dispense a fire fighting agent within the enclosure. A penetrating device is attached to the forward end of a rotatable barrel, providing for penetration of the titanium wall of an enclosure and insertion of the forward end of the barrel through the titanium wall. The rotatable barrel is mechanically coupled to a controllable actuating device, such as a motor. The actuating device is used to rotate the barrel, thereby driving the penetrating device to penetrate into the enclosure, allowing insertion of the penetrating device and the forward end of the rotatable barrel into the enclosure. Fire fighting fluid is dispensed into the enclosure through a fluid channel in the barrel.
