A damper member may include a gel-like member and a first film joined to a first surface of the gel-like member in a thickness direction, in which a side surface of the gel-like member located between a second surface opposite to the first surface of the gel-like member in the thickness direction and the first surface is opened.

A hopper charged with a powder material, a screw arranged below the hopper and exposed at a supply port formed at the bottom of the hopper, and a rolling element in contact with the screw at the supply port are provided. The rolling element is larger than a space between end portions of the supply port and a screw groove of the screw.

A heat blanket system including a blanket including a first sub-area and a second sub-area. The heat blanket system also includes heating elements printed on the blanket. First spacings between first ones of the heating elements in the first sub-area varies relative to second spacings between second ones of the heating elements in the second sub-area. The first spacings and the second spacings vary according to a design. The design is configured for use on a uniquely defined rework area on a uniquely defined composite material object including a third area including a heat sink region and a fourth area including a non-heat sink region. The first sub-area is sized and dimensioned to be placed over the third area. The second sub-area is sized and dimensioned to be placed over the fourth area.

A method for producing a reinforcing bar by pultrusion, the method comprising the steps of: a) providing a source of fibres; b) assembling the fibres into a bundle; c) impregnating the bundle with a thermosetting resin; d) eliminating excess resin from the bundle; e) compressing the bundle in a centripetal manner; f) exposing the bundle to a radiant energy source; g) spraying particles onto a surface of the bundle; and h) exposing the bundle to radiation in order to initiate, on the surface of same, the polymerisation of the resin. The present invention also concerns a system provided with corresponding devices in order to be able to implement the method. The present invention also concerns a reinforcing bar obtained with the described method and/or system.

A lens with an embedded foil is produced, comprising the steps of providing a first mold and a second mold, providing a functional foil, positioning and attaching the functional foil on the first mold, aligning the second mold relatively to the first mold, sealing the mold cavity between the first mold and the second mold, and filling a curable monomer mixture into the mold cavity, wherein either the molds are heated before the alignment step or the molds are heated after the sealing step and the following filling step is conducted with a heated monomer, or the heating of the molds follows the filling step of the UV curable monomer, followed by a UV curing step of the heated UV curable monomer mixture within the heated mold cavity.

Aspects of the disclosure are directed to methods and apparatus involving the extrusion of polymers or other materials. As may be implemented in accordance with various embodiments, a polymer is delivered into an inlet of a nozzle structure having the inlet and an outlet. The polymer is viscously heated and melted by rotating the nozzle structure about an axis extending through the inlet and the outlet, therein facilitating extrusion of the melted polymer through the nozzle structure outlet. A polymer supply may deliver the polymer into the nozzle structure inlet, and a coupler may facilitation rotation of the nozzle structure. A driver may further operate to control rotation of the nozzle structure relative to the coupler, for instance by generating a rotational output that causes rotation of the nozzle structure.
