An electrical discharge machining (EDM) electrodes and associated methods are provided. An EDM electrode includes a holder rotatable about a rotation axis and a plurality of electrode elements attached to the holder and circumferentially arranged around the rotation axis. Respective positions of the electrode elements are radially adjustable relative to the rotation axis.

The invention is directed to straight, consistent body scores on plastic corrugated boxes and a process for making the body scores.

Adhesive bondlines in a cell-based structural array are thermally cured using tooling blocks inserted into the cells. The tooling blocks have embedded susceptors that are inductively heated by an alternating electromagnetic field generated by an electromagnet.

A component, including a part, comprising a honeycomb-like structure formed from at least a seamless resin-infused fiber composite material. The honeycomb-like structure includes a first plurality of cells, and a second plurality of cells, different than the first plurality of cells.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

The invention is directed to straight, consistent body scores on plastic corrugated boxes and a process for making the body scores.

A method of repairing an acoustic core cell of an acoustic sandwich panel is provided. The method comprises inserting a core repair splice adjacent to a number of damaged walls of the acoustic core cell of the acoustic sandwich panel, nesting the core repair splice onto the number of damaged walls, and bonding the core repair splice to the number of damaged walls and thereby to repair the acoustic core cell of the acoustic sandwich panel.

Screw elements, extrusion apparatus, and methods of manufacturing honeycomb bodies are described herein. A segment for a ceramic batch screw extruder machine has at least one pump and mix screw element. The pump and mix screw element has a pitch, a diameter, and a pitch to diameter ratio of 0.8 to 2.6.

Nozzles are presented, for application of a setting resin into cells of a honeycomb core to provide the panel with reinforced segments. The nozzle comprises a connector portion and an application head, where the connector portion is adapted to receive setting resin from a resin dispensing device and deliver the setting resin to the application head, and the application head comprises: an exit hole, and a flange surrounding the exit hole. The flange comprises a bottom surface which comprises a planar surface which planar surface has a minimum width around the exit hole. The bottom surface of flange curves upward at its outer perimeter. In some embodiments, the nozzle is optically translucent or transparent. In addition, methods of applying a setting resin into cells of a honeycomb core to form a honeycomb core reinforcement are presented. In some embodiments, the setting resin is a low density void filler.

Freeform, additive manufacturing equipment, processes and products, including residential, commercial and other buildings. A movable extruder places extrudate that solidifies in open space to create scaffolding or skeletons of buildings and other products. Elongated extrudate elements are fused to each other or connected by other means to form a cellular structure. Filler material such as polymeric insulating foam may simultaneously or thereafter be placed within the cellular structure to contribute desired strength, rigidity, insulative, barrier or other properties. Finish materials may also be applied.
