A method of manufacturing a cover glass is provided. The method comprises providing a glass base; forming a glass support portion by printing glass onto the glass base; and applying glass wool onto the glass support portion.

A sealing device for sealing an opening of an apparatus. The sealing device has a head that defines a cavity and a neck that defines a passage disposed between the cavity at a first end of the neck and an aperture at a second end of the neck. The aperture is configured to collapse and expand, having a first diameter in a collapsed configuration and a second diameter in an expanded configuration. The interior surface of the neck includes an engagement interface that is configured to releasably engage with a spacer. When the engagement interface is engaged with the spacer, the neck is in the expanded configuration.

Described are methods and systems for identifying processing locations in composite layups. An optical magnetic marker is magnetically supported by a layup tool at a target position, such that a portion of the marker protrudes above the tool processing surface. When a composite layup is placed onto that surface, the protruding portion extends into the layup at a processing location. When the layup is cured, the marker is permanently embedded into the layup. Separating the cured layup from the tool removes the marker from the tool and allows an additional marker to advance into the target position for processing another layup. The embedded marker or, more specifically, marker's reflective surface is used during optical inspection of the layup surface to precisely determine the processing location. In some examples, the marker is consumed while the layup is processed at that location,

A method is provided for connecting hollow profiles (1-4) in a joint (10) to produce a load-bearing structure (5). The method includes placing ends of hollow profiles (1-4) in a mold and pressing the ends together with at least one semi-finished product to connect the ends of the hollow profiles to the semi-finished product.

A method for additively manufacturing a tip structure on a pre-existing part includes: a) placing the part in a build space of a beam-assisted additive manufacturing setup and below a transparent aligning plate, b) engraving a top contour of the part onto the aligning plate with an energy beam of the setup, c) aligning a top surface of the part such that the top surface coincides with the engraved contour, d) removing the aligning plate from the setup, and e) additively manufacturing the tip structure according to a predefined geometry on the top surface.
