摘要:
A flexible co-extruded three layer film comprising outer layers of high pressure, low density polyethylene and a core layer of low pressure, low density polyethylene. The film is produced by a blown film tubular extrusion process at conventional rates and temperature and yet is free of melt fracture even though the low pressure, low density polyethylene would otherwise exhibit melt fracture.

A multilayer plastic film suitable for use in the manufacture of garbage and trash bags wherein the film comprises one or more layers representing at least one first outer layer and may include a core layer made with low pressure, low density polyethylene and one or more layers representing at least one second outer layer made with high pressure, low density polyethylene which may contain up to forty-two percent by weight of low pressure, low density polyethylene.

A therapeutic lens for the treatment of an epithelial defect comprises a layer of therapeutic material disposed over the stroma and/or Bowman's membrane to inhibit water flow from the tear liquid to the stroma and/or Bowman's membrane, such that corneal deturgescence can be restored to decrease corneal swelling and light scattering. The layer may cover and protect nerve fibers to decrease pain. The layer may comprise an index of refraction to inhibit light scatter from an anterior surface of the stroma and/or Bowman's membrane. The lens may comprise a curved anterior surface that provides functional vision for the patient when the epithelium regenerates. The layer of therapeutic material can be positioned on the eye in many ways, for example with a spray that is cured to adhere the layer to the exposed surface of the stroma and/or Bowman's membrane.

A heat-shrinkable multilayer film suitable for use in the packaging of primal meat cut, includes a first outer layer comprising a blend of a propylene-ethylene copolymer, a (butene-1)-ethylene copolymer, and a thermoplastic elastomer selected from the group consisting of ethylene-propylene copolymers and ethylene-propylene diene terpolymers; a first core layer connected to the first outer layer and being capable of being stretched during the biaxial orientation of the multilayer film and comprising an extrudable adhesive; a second core layer connected to the first core layer and serving as an oxygen barrier to protect the meat cut from spoilage and being compatible to the biaxial orienting and heat shrinking of the film; and a second outer layer comprising an ethylene vinyl acetate copolymer; the multilayer film being biaxially oriented.

Systems, assemblies and methods for assembling a sheath member with respect to a spinal stabilization device are provided. The disclosed sheath assembly includes at least one connector ring mounted with respect to a sheath member. The connector ring defines an inner wall that shields the sheath member from elements positioned therewithin, e.g., spring members, and generally includes a plurality of radially-spaced notches. The connector ring receives the sheath member within an internal cavity and is secured thereto by crimping, compression or swaging. The sheath assembly may be mounted with respect to a spinal stabilization device by crimping, compressing or swaging the connector ring to an underlying structure, e.g., an end cap or associated flange. The internal cavity of the connector ring is generally defined by an inner face, an outer wall and an intermediate apex region. Methods for assembly are also disclosed.

A field effect semiconductor device comprising a high permittivity silicate gate dielectric and a method of forming the same are disclosed herein. The device comprises a silicon substrate 20 having a semiconducting channel region 24 formed therein. A metal silicate gate dielectric layer 36 is formed over this substrate, followed by a conductive gate 38. Silicate layer 36 may be, e.g., hafnium silicate, such that the dielectric constant of the gate dielectric is significantly higher than the dielectric constant of silicon dioxide. However, the silicate gate dielectric may also be designed to have the advantages of silicon dioxide, e.g. high breakdown, low interface state density, and high stability. The present invention includes methods for depositing both amorphous and polycrystalline silicate layers, as well as graded composition silicate layers.

A running tool for installing a casing hanger in a subsea conductor also serves to wash cement from the annulus surrounding the casing hanger. The running tool includes a tubular tool body which connects to a string of conduit. An internal sleeve mounts in the interior of the tool body for rotational movement only. A torque member lowers through the conduit to the internal sleeve for rotating the internal sleeve. A wash port extends from the interior of the tool body to the exterior of the tool body. An external sleeve mounts to the exterior of the tool body for axial movement between a closed position, closing the wash port, and an open position, opening the wash port. A linking mechanism between the internal and external sleeve causes rotary movement of the internal sleeve to move the external sleeve axially.
