    摘要: Alloys comprising by weight 70-82% Copper, 6-10% Aluminum, 0.1-24% Zinc and 0.1-12% Manganese are particularly suited for use as the material of heat recoverable articles as they exhibit good ductility and stability and are easily worked by hot working techniques. Additionally, they have M.sub.s temperatures which enables them to be fabricated into heat recoverable articles useful in many applications.A heat recoverable article, made from a quarternary alloy of copper, aluminum, manganese and zinc whose composition falls on or near the eutectoid line, is particularly suited for use in circumstances where the article has been recovered from its recoverable state under conditions such that a degree of unresolved recovery remains.

    摘要: The invention is a method and device for providing a protective coating for the inside of pipes, said method utilizing a device which is remotely actuated from outside said pipes. Specifically, the device comprises a memory metal delivery means, a corrosion resistant liner means, and a bonding means, said device expanding upon application of heat toward the inner wall of the pipe to cause the bonding means to flow progressively between the liner means and the inside of the pipe to thereby preclude air entrapment and to bond said liner means to the inside of the pipe.

    摘要: Some metallic compositions that undergo a reversible transformation between austenitic and martensitic states as a result of being heated or cooled through critical temperature ranges may lose a portion or all of the ability to revert from martensite to austenite. That loss can be inhibited by "aging" the composition prior to its conversion to the martensitic state by holding it at a temperature at which it exists in the austenitic state. The time required to significantly inhibit loss of reversibility may vary as the nature of the composition changes. For a specific composition, the time required typically is shortened as the holding temperature is raised.The ability of a composition to respond to preconditioning methods by which its A.sub.s temperature can be elevated may also be improved by aging in the austenitic state prior to attempting preconditioning.

    摘要: Detection of events, e.g. liquid leaks and other changes in varibles. The event causes two conductors to become electrically connected, and thus creating a system in which the connection point can be located by measuring the potential drop from one end of one of the conductors (called the locating member) to the connection point. Preferably a fixed current flows through the connection, so that the result is independent of the resistance of the connection. The locating member can be a continuous resistive wire, preferably coated with a conductive polymer; such a locating member can form part of a sensor cable in which the elongate components of the circuit are in a wrapped configuration, or part of a cable in which the conductors are separated by a member shaped to prevent capillary action of a liquid from connecting the conductors. Alternatively the locating member comprises a plurality of discrete resistors. Preferably the system is arranged so that the sensitivity of the system is not dependent on the location of the fault and/or is such that only connections within a certain range of resistance will activate the system. The voltage drop is preferably calculated by comparing it to the voltage drop over a resistor of known size. Particular event-sensitive connection means are preferably employed for the detection of hydrocarbons and for the detection of acids.
