Abstract: Disclosed are medical devices of aliphatic polyketone polymers and/or polyketone polymer compositions comprising at least one aliphatic polyketone and at least one plasticizer. Also disclosed are polyketone compositions that comprise at least one aliphatic polyketone and at least one plasticizer.
Abstract: A storage container for containing liquids that harden, that comprises a threaded surface and a closure having threading complimentary to the threads of the storage container, wherein the threads of the threaded surface are coated with a non-stick coating to prevent the liquid from hardening on the threads of the container and bonding the closure with to the container.
Abstract: Radome which is mainly constituted of at least one porous ceramic material. The radome is useful as a cover for protecting a radar, which is excellent in weather resistance, machinability and relative dielectric constant. The porous ceramic radome material may be coated or impregnated with a resin, amorphous silica or borosilicate glass in order to improve the tightness and the resistance to heat and oxidation.
Abstract: A reinforced elastomeric bag for use within an electric submergible motor protector has a generally cylindrical bag body formed as a single continuous structure, and a plurality of reinforcing ribs longitudinally disposed about an inside surface of the bag body. The reinforcing ribs prevent the bag body from collapsing onto and blocking oil inlet ports within the motor protector.
Abstract: A substrate coated with a liquid crystal polymer with an intervening tie layer. A second embodiment provides a surface layer disposed on the LCP layer, sandwiching the LCP layer between the surface layer and the substrate. Methods for constructing the above also is provided.
