摘要： A disclosed method is suitable for repairing a blade of a turbomachine rotor, particularly a turbomachine fan, that includes a vane made from an organic-matrix composite and a metallic shield that is bonded to a leading edge of the vane and has a damaged region. The method includes steps of resetting the leading edge of the vane cooling the entire vane, followed by a step of refilling the damaged region by adding a metallic material to this damaged region and melting the material using a laser, and a step of tailoring the damaged region by machining the molten material.

摘要： A method for repairing a leading edge of wind turbine blade is provided. In the method an adhesive is applied to an eroded surface of the leading edge of the wind turbine blade for substantially re-establishing geometry of the leading edge of the wind turbine blade. Thereafter, a leading edge protective shell is applied on the leading edge such that the leading edge protective shell adheres to the eroded surface with only the adhesive between the eroded surface and the leading edge protective shell, wherein a shape of the leading edge protective shell corresponds to aerodynamic outer profile of the leading edge. A two component modified-silane polymer adhesive is used to mount a soft polymer leading edge protective shell.

摘要： A lining drum which has a tubular body having open ends, an inlet for compressed air and an outlet for liner is disclosed. The lining drum has end pieces removably attached to the tubular body for closing the open ends of the tubular body, a rotatable shaft inside the tubular body and a crank for rotating the shaft. The end piece has a spring-loaded flange mounting, wherein bias of springs pushes the flange mounting towards the tubular body and a closed position of the flange mounting, and air pressure inside the lining drum pushes the flange mounting away from the tubular body and towards an open position of the flange mounting.

摘要： A method of recoupling components of a medical device in a desired orientation during reprocessing of the medical device. The method uses a binder to return the components to an adhered condition from a separated condition. The method comprises receiving the components of the medical device in the separated condition with the component spaced from the desired orientation. The components of the medical device are cleaned and arranged in the desired orientation. The binder is applied to recouple the components in the desired orientation to return the components to the adhered condition.

摘要： A liner assembly and method for lining a damaged pipe junction between a main and lateral pipe is provided. The liner assembly includes a main liner member and a lateral liner tube. A collar disposed near the juncture between the main liner member and lateral liner tube is impregnated with a liquid hydrophobic or hydrophilic material capable of curing in a flexible or rigid state with the material expanding in the presence of water. The hydrophobic or hydrophilic material can also be applied without the use of the collar. When the liner assembly is pressed against the main and lateral pipes, a portion of the hydrophilic or hydrophobic material is forced into the damaged pipe junction.
