9 results about "Reticulated foam" patented technology

Disclosed is an aircraft structure comprising at least one aircraft structural element defining a volume; a fuel-handling component arranged within the volume and configured to handle a fuel; a purging system comprising an inlet and an outlet, the purging system configured to provide a flow of purge gas from the inlet, through the volume, to the outlet, to thereby purge leaked fuel from the volume; and a flow guide member formed of a reticulated foam, arranged within the volume and externally to the fuel-handling component, and configured to guide the flow of purge gas within the volume. An aircraft comprising the aircraft structure is also disclosed.

A pillow uses a fan assembly in the pillow to cool the sleeping surface of the pillow. The fan assembly uses two fans to move ambient air through a middle layer of reticulated foam and then through air passages extending through at least one layer of foam. A bottom piece of foam is either semi-permeable or impermeable to airflow so that most, if not all, of the air moved by the fans exits the top of the pillow to cool the pillow. A chargeable power source powers the fans via a circuit board which may have an LED light to indicate the status of the power source.

Disclosed is an aircraft structure comprising: at least one aircraft structural element defining a volume; a fuel distribution component, arranged within the volume, configured to hold fuel internally and transport held fuel through the volume; and at least one packing element formed of a reticulated foam, arranged within the volume, and at least partially surrounding the fuel distribution component. An aircraft comprising the aircraft structure is also disclosed.

Systems, apparatus, and methods for manufacturing foam inserts for fuel tanks are disclosed. An example method includes forming, via additive manufacturing, a foam insert having a shape based on one or more properties of a fuel tank that is to receive the foam insert; and quenching the foam insert to form a reticulated foam insert.

The invention discloses a monatomic cobalt coordination foamy carbon catalytic material as well as a preparation method and application thereof. The material is obtained by mixing a cobalt precursor, melamine, a lignosulfonate precursor and a foaming agent and carrying out hot-pressing foaming molding, segmented carbonization and acid pickling. The material is a three-dimensional net-shaped foamy carbon skeleton, cobalt is anchored in the carbon skeleton in a monatomic form and is coordinated with nitrogen and sulfur atoms in the carbon skeleton to form an S-Co-N4 site through a covalent bond, and atomic-scale efficient active site construction is achieved. The material has a micro-scale pore bubble structure with coexisting open pores / closed pores, and continuous mass transfer channels and reaction sites are provided. Pollutants and peroxymonosulfate are enriched on a mesoscale interface of a pore channel and react with monatomic sites, so that generation of active species and degradation of the pollutants are promoted. On the macroscopic scale, the material serves as a recoverable photo-thermal catalysis unit, the photo-thermal coupled Fenton-like process is achieved under the illumination condition, and the material is suitable for deep treatment of new pollutants in a water body.

An aircraft structure and an aircraft are disclosed, the aircraft structure comprising at least one aircraft structure element, the aircraft structure element defining a volume; a fuel treatment component disposed within the volume and configured to treat fuel; a purge system comprising an inlet and an outlet, the purge system configured to provide a flow of purge gas from the inlet through the volume to the outlet to thereby purge leaked fuel out of the volume; and a flow directing member formed of a mesh foam, disposed within the volume and outside the fuel processing component, and configured to direct a flow of purge gas within the volume.

The present invention relates to a protection filter for adiabatic pre-cooling system. The protection filter (1) has an intake side and an outflow side. The protection panel (1) comprises a frame (10) and multiple layers arranged within the frame (10), wherein the following layers are arranged one by one starting from the intake side of the protection filter (1): a front expanded mesh (2); a first corrugated metal mesh (3) having corrugations (13); a second corrugated metal mesh (4) having corrugations (14); a honeycomb mesh (5), a reticulated foam panel (6), a third corrugated metal mesh (7) having corrugations (17) and a back expanded mesh (8). The corrugations (13) of the first corrugated metal mesh (3) are arranged orthogonal the corrugations (14) of the second corrugated metal mesh (4).
