Method which is intended for producing an endless semi-finished product and having the following steps: feeding a silicone tube and a separate internal conductor, wherein the internal conductor runs in a first interior space formed by the silicone tube; encasing the fed silicone tube by production of an endless fibre tube, which encloses the silicone tube from the outside. The silicone tube is expanded so that a gap is formed between the silicone tube and the endless fibre tube. A matrix material is feed into the gap connecting the silicone tube and the endless fibre tube by virtue of the matrix material being cured.

The present invention relates to multilayer films used to protect a surface, in particular, to such films used to protect surfaces of articles e.g., mobile electronics display protections, smartphones, tablets), industrial touch screens (e.g. machine interfaces), UV stable surfaces and glass protections for machine housings and cockpits (e.g. caterpillars, dumpers), etc.), and, more particularly, to such a multilayer protective film backed by a silicone-based pressure sensitive adhesive (PSA) and having either an aliphatic polyurethane layer or an aliphatic thermoplastic polyurethane layer on top of an aliphatic thermoplastic polyurethane layer, where the two aliphatic polyurethane layers have different physical and/or chemical properties. The present invention also relates to an article that is protected by the multilayer film as well as a method for making the multilayer protective film.

A method of manufacturing a plurality of optical elements includes providing a first wafer (200) having lower alignment features (192) arranged on a first surface of the substrate, providing a second wafer (201) comprising, on a replication side, a plurality of replication sections, each replication section defining a surface structure of one of the optical elements, the second wafer (201) further comprising upper alignment features (194) protruding, on the replication side, further than an outermost feature of the replication sections, depositing liquid droplets (196) on the first side of the first wafer (200), and bringing the second wafer (201) and the first side of the first wafer (200) together, with liquid droplets (196) between the first wafer (200) and the second wafer (201), the upper alignment features (194) contacting the liquid droplets (196) on the lower alignment features (192) on the first side of the first wafer (200), and thereby causing the second wafer (201) to align with the first wafer (200) by capillary action.

Presented are fiber-reinforced polymer (FRP) composite components with integrated polymer parts, methods for making/using such FRP composite components, and vehicles equipped with battery packs sealed inside FRP battery enclosures by integrated elastomeric seals. An FRP composite component, such as a rigid battery tray basin, includes a component body that is formed with a polymer matrix material, such as a fast-curing epoxy resin. A fiber preform, such as a multiaxial-fiber fabric sheet, is encapsulated within the component body and formed with a cluster of fibers bound together in a predefined formation. A polymer seal, such as an elastomeric bulb seal, includes a seal head and a mounting base. The seal's mounting base is stitched to the fiber preform and at least partially encapsulated within the component body. The seal head protrudes from the fiber preform and extends through an aperture in the component body.

The present invention relates to a process and apparatus for the preparation of a bonded substrate. More particularly, the present invention relates to a PDMS bonding apparatus. More specifically, the present invention relates to a PDMS bonding apparatus which uses plasma to bond PDMS to a substrate. The present invention discloses a PDMS bonding apparatus and process for using said apparatus, the apparatus comprising: a process chamber (100) forming a sealed processing space (S) for bonding of PDMS (polydimethylsiloxane); a first support (200) installed in the process chamber (100) and which supports the PDMS (1); a second support (300) installed in the process chamber (100) opposing the first support (200) and which supports a bonding object (2) which is bonded to the PDMS (1); a gas injection unit (400) which ejects process gas between the first support (200) and the second support (300), and; a plasma generator (500) which creates a plasma atmosphere within the process chamber (100).

A method of manufacturing an intraocular lens (IOL). Method includes mounting the anterior part of the IOL on a first nest where the anterior part defines a receptacle and has a haptic extending from an anterior face. A pre-determined desired amount of fluid is introduced in the receptacle. A bonding agent can be introduced into a trough of posterior part of the IOL and the posterior part can be mounted on a second nest. Force can be applied to draw the first nest towards the second nest (or vice versa) or the first and second nests can be placed in a vacuum sealed chamber and the first and second nest can be mechanically drawn together. Alternatively, the first and second nests can be placed in an inert gas chamber such that the posterior part and the anterior part are mechanically join together to form a fluid filled integral IOL.

A 3D printing system includes a tank containing a liquid photopolymer resin. A textured surface is disposed in the tank. The textured surface is configured such that light passes through therethrough and into the liquid polymer resin. A layer of an inert material is disposed on the textured surface.

A process for edge sealing during an overmolding of a polyurethane on a substrate part comprising the steps of: A. Providing an injection mold cavity including a first side platen forming mold and a second side mating part forming platen; B. Molding a substrate part formed between the first side platen and the second side mating part forming platen; C. Providing a second overmold cavity for overmolding a polyurethane or other covering over the substrate part; and D. Providing a seal at the flashing edge of the second overmold cavity and overmolding the polyurethane or other covering over the substrate part such that there is substantially no flashing material where the seal is located.
