摘要:
A dispenser is used for dispensing flexible material from a coil. The dispenser includes a frame, a coil carriage mounted to the frame and a brake/payout assembly mounted to the frame. The frame defines an axis of rotation about which the coil carriage rotates. The coil is securable within the coil carriage for rotation with the carriage. The brake/payout assembly is operably mounted to the frame and is moveable toward and away from the coil carriage. The brake/payout assembly is biased toward the coil carriage for engagement with the carriage. The brake/payout assembly engages the coil carriage to slow rotation of the carriage and includes a nip region through which the flexible material traverses during payout.

A family of environmentally-resistant alloys is provided which are suitable for forming a blade tip for a turbine blade of a gas turbine engine. The blade tip alloys preferably have a chemical composition of, in weight percent, about 14 to about 18 percent chromium, about 6.45 to about 6.95 percent aluminum, about 9.75 to about 11.45 percent cobalt, about 5.95 to about 6.55 percent tantalum, about 1.85 to about 2.35 percent rhenium, about 0.05 to about 1.75 percent hafnium, about 0.006 to about 0.03 percent zirconium, about 0.02 to about 0.11 percent carbon, up to about 1.1 percent silicon, up to about percent 0.01 percent boron, with the balance being nickel and typical impurities.

A method and composition for treating cystic fibrosis comprising administering to a patient a first component, a second component, and preferably a third component. The first component is an inhibitor which is specific for a cGMP-inhibited type III cAMP phosphodiesterase, preferably milrinone or amrinone; the second component is an adenylate cyclase activator, preferably forskolin, isoproterenol or albuterol; the third component is cAMP or a cAMP analog which activates protein kinase A.
