Abstract:
A method of manufacturing a turbine blade includes providing a multilayer polymeric film. The multilayer polymeric film includes a first layer including an acrylic-based adhesive, a second layer disposed over the first layer, and a third layer disposed over the second layer. The second layer includes a blend of an acrylic polymer and fluorpolymer. The third layer has at least a portion with a smooth surface. The third layer includes fluoropolymer. The method further includes laminating the multilayer polymeric film over at least a portion of a turbine blade work piece. The first layer contacts the turbine blade work piece.
Abstract:
A multi-layer film includes a first layer including a blend of diene elastomer and not greater than about 40% by weight polyolefm. The multi-layer film also includes a second layer directly contacting and directly bonded to the first layer. The second layer includes a fluoropolymer.
Abstract:
The disclosure is directed to a coupling 100 including a main body 102, a rotatable member 122, and a seal member. The main body has an internal passageway 108 for fluid flow therethrough, and includes a first portion 110 defining a first end 112 of the coupling and includes a second portion 114 defining a second end 116 of the coupling and forming an abutment structure 106. The rotatable member 122 encircles the main body along the second portion, and includes an engagement structure 154 for engaging a complementary structure. The rotatable member has first 146 and second 148 opposite axial ends, and the seal member is disposed between at least one of the first and second opposite axial ends of the rotatable member and the main body.
Abstract:
The disclosure is directed to a multilayer film (100) including a first layer (102) and a second layer (104). The first layer (102) has a fluorinated polymer. The second layer (104) has a melt strain-hardening component and forms no more than about 30% by volume of the multilayer film (100).
Abstract:
In one embodiment, the disclosure is directed to a chemical mechanical polishing retaining ring. The chemical mechanical polishing retaining ring includes a support formed of a first material comprising a first polymer and a wear portion formed of a second material comprising a second polymer. The first material has an elastic modulus greater than the elastic modulus of the second material.
Abstract:
A tape for providing thermal contact between an energy generating device and a energy dissipating device is disclosed. The tape comprises a thermally conductive material configured to be adhesively coupled to one of the energy devices, and a tab. The first portion of the thermally conductive material can be separated from the tab by removal of the tab along a weakened interface. The tape may further comprise a sheet such as a sheet of aluminum foil. The weakened interface typically exists between two portions of the sheet or two portions of the thermally conductive material, but could exist anywhere. The weakened interface can be a perforated line. The weakened interface can also be formed along a straight line.
Abstract:
A tolerance ring (316) can be disposed between an inner component (306) and an outer component (302), the inner and outer components defining stepped sidewalls. In an embodiment, a preassembly can include an outer component defining a bore (304) having a stepped inner sidewall (310), an inner component (306) having a stepped outer sidewall (312), and a tolerance ring (316) adapted to be disposed between the inner component and the bore. In an embodiment, an assembly can include an outer component defining a bore having a stepped inner sidewall, an inner component having a stepped outer sidewall, and a tolerance ring disposed between the inner component and the bore. In an embodiment, a hard disk drive preassembly (300) can include an actuator arm defining a bore having a stepped inner sidewall, a pivot having a stepped outer sidewall, and a tolerance ring adapted to be disposed between the pivot and the bore.
Abstract:
A flexible tube includes a polymer composition of a poly vinyl chloride having a molecular weight greater than about 1.0 inherent viscosity (IV) and a bio-based plasticizer. Further, a method of forming a flexible tube is provided. The method includes compounding a poly vinyl chloride having a molecular weight greater than about 1.0 inherent viscosity (IV) with a bio-based plasticizer to form a polymer composition and extruding the polymer composition into the flexible tube.
