    摘要: Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer consisting essentially of one or more ethylene-propylene copolymers. Further still, the multilayer film may include a second skin layer consisting essentially of one or more ethylene-propylene-butylene terpolymers. And yet further, the multilayer film may be oriented in at least one direction, and at least two layers of the multilayer film are coextruded.

    摘要: This disclosure provides methods, systems and devices that may be used to measure, calculate, and orient a device such as a drill bit in a downhole environment. To that end, disclosed are fiber optic gyroscopes, wherein the fiber optic gyroscopes comprise elliptical fiber optic cable coils in a mutually orthogonal arrangement that is tilted relative to a length of a supporting shaft, e.g., tube. Light travels in opposite directions within each of the elliptical fiber optic cable coils, and, subsequently, sensors detect differences in time for each light path of the light that traveled in opposite directions within each one of the elliptical fiber optic cable coils. The elliptical nature of the fiber optic cable coils minimizes the cross-sectional area of the mutually orthogonal arrangement, and thereby makes it well-suited for use in downhole environments where space is at a premium. This disclosure also may provide an inertial measurement unit.

    摘要: Disclosed are methods, compositions and structures that, in one example embodiment, is a film that includes a multilayered base film comprising a core and at least one printable coating applied to at least one outer surface of the multi-layered film. The at least one printable coating may include an acrylic-based polymer, and have a dry coating weight is within a range from 0.1 g/m2 through 0.9 g/m2 with a pH of at least 9. The film complies with European regulations for use in food-contact packaging and labeling, which are examples of applications for the disclosed films.
