    摘要： The present invention pertains to a polyethylene film and a process for manufacturing such film. The polyethylene film may have a ratio between the strength in a first direction in the film plane and the strength in a second direction in the film plane perpendicular to the first direction in the range of 0.1-10:1, the strength in at least one direction being at least 0.2 Gpa. The process for manufacturing a polyethylene film may have a starting UHMWPE polymer with an average molecular weight of at least 500,000 grams/mole, an elastic shear modulus determined directly after melting at 160° C. of at most 1.4 MPa, and a Mw/Mn ratio of at most 6 to a solvent-free compacting process and a stretching process under such conditions that at no point during the process the temperature of the intermediate polymer film is raised to a value above its melting point.

    摘要： Method and apparatus for preparing a silicone hydrogel lens including heating a cast lens to drive off an organic diluent by moving the cast lens continuously through heating and cooling zones to provide a first-in-first-out handling system. The zones are either horizontally or vertically arranged. An apparatus embodiment of a vertical heating zone includes outer and inner concentric shells arranged in a heating chamber. One of the shells rotates about a vertical axis relative to the other. The outer shell has a spiral rail extending into the space between the outer and inner shells and the inner shell has a plurality of vertical ribs spaced about its periphery. A lens carrier placed on the rail is engaged and driven along the spiral rail by one of the ribs responsive to the relative motion between the outer and inner shells.
