METHOD OF FUSING THERMOPLASTIC COMPOSITE STRUCTURES
A method for fusing thermoplastic composite structures includes placing a substructure on an inner surface of a skin that is laid up on a shaping surface of a tool configured to maintain the shape of an outer mold line. The method further includes applying at least one insulation layer over a flange of the substructure and over exposed portions of the inner surface of the skin not in contact with the substructure, and applying a vacuum bag to at least partly enclose the skin and the substructure. The method yet still further includes applying heat to the shaping surface to fuse the substructure to the skin such that the skin exceeds its melting point and at least a portion of a raised segment of the substructure does not exceed its melting point.
Systems, Cure Tools, and Methods for Thermally Curing a Composite Part
An example method for curing a composite part includes placing the composite part onto a topside of a cure tool, and a bottom surface of the composite part contacts the topside of the cure tool and a top surface of the composite part is opposite the bottom surface of the composite part. The method also includes placing the cure tool and the composite part into an autoclave, using the autoclave to apply external heat to the cure tool and the composite part so that air flows over the top surface of the composite part to heat the top surface, and applying additional heat to a backside of the cure tool via radiation provided by at least one heating source of the cure tool, so as to reduce a temperature difference between the backside of the cure tool and the top surface of the composite part being cured.
Using the light adjustable lens (LAL) to increase the depth of focus by inducing targeted amounts of asphericity
In general, the present invention relates to optical elements, which can be modified post-manufacture such that different versions of the element will have different optical properties. In particular, the present invention relates to lenses, such as intraocular lenses, which can be converted into aspheric lenses post-fabrication. Also, the present invention relates to a method for forming aspheric lenses post-fabrication.

Method for producing a wind turbine rotor blade, and wind turbine rotor blade
A method of producing a wind turbine rotor blade For that purpose metal particles, metal powder or metal chips are mixed into a matrix used to produce the rotor blade. Inductive heating of the matrix with the metal particles, metal powder or metal chips is then effected to harden the matrix in at least one portion of the wind turbine rotor blade.
Method for obtaining at least one structure approximating a sought structure by reflow
A method for determining at least one reflow parameter for obtaining a structure approximating a sought structure by reflowing an initial structure different to the sought structure, the initial structure including at least one pattern formed in a thermo-deformable layer arranged on a substrate. The thermo-deformable layer forms a residual layer surrounding each pattern and from which each pattern extends such that each pattern has an interface only with the surrounding medium. The method includes: predicting progression over time of geometry of the initial structure subject to reflow, to obtain a plurality of predicted structures each associated with reflow parameters including at least a reflow time and a reflow temperature; computing correlation values of the geometry of each predicted structure with respect to the sought structure; identifying reflow parameters for obtaining the predicted structure offering a highest correlation value.
Method for curing a liner tube
The present invention relates to a method for rehabilitating lines, in particular sewers, shafts or the like, a curing device being activated or having been activated for curing the curable and/or curing ply, and an advancement of the curing device in the lining sleeve and in particular the power output of the curing device being controlled in an open-loop or closed-loop manner in dependence on the temperature sensed by the temperature measuring device on the outer side of the curable ply.
