The pallet has a plurality of track rails and attachment points for attaching a litter stanchion set, capable of holding a patient in a litter, and/or for attaching a seat to the surface of the pallet. The pallet also includes a plurality of pallet lips and cargo rings on the periphery which provide locations to attach one or more pallet extensions, pallet spacers and/or pallet ramps to increase the usable surface area of a pallet, as well as facilitate safe passage on, off and between pallets by reducing tripping hazards inherent in cargo aircraft.

Disclosed are nano-engineered porous ceramic composite filtration media for removal of phosphorous contaminates from wastewater and other water or liquid sources. Such porous ceramic media has high surface area and an interconnecting hierarchical pore structure containing nano-iron oxide/oxyhydroxide compounds, as well as other nano materials, surfactants, ligands or other compounds appropriate for removing higher amounts of phosphorous or phosphorous compounds. The composite media can be modified with nano-phased materials grown on the high surface area and addition of other compounds, contains hierarchical, interconnected porosity ranging from nanometer to millimeter in size that provides high permeability substrate especially suited for removal of contaminants at the interface of the water or other fluids and the nanomaterial or surfactants residing on the surfaces of the porous structure.

A storage device mounted within a door frame is disclosed for storage and organization of fashion accessories or similar articles is provided. The device comprises an outer door supported by the door frame, an interior door enclosing a hollow door interior for storage of articles, and at least one interior panel within the hollow door interior to separate an interior cavity therein and limit access thereto via a hidden locking mechanism. The interior panel provides separation of the internal cavity from the hollow door interior, increases surface area of the hollow door interior, and segregates a hidden interior cavity therein. The back wall of the interior cavity also provides a location for further hooks and shelving for storage. The device may be provided within the interior of a larger door, or as a door insert adapted to be incorporated into an existing door.

A storage device mounted within a door frame is disclosed for storage and organization of fashion accessories or similar articles. The device comprises a door having an internal cutout, wherein an internal cavity is provided for storage of articles in a condensed space, which can be accessed via a second, cutout door. A full length mirror is mounted to the interior of the second door along with peg board to allow attachment of accessory hooks for hanging items. One or more hinged panels inside of the interior cavity provide separation of the internal cavity and increased surface area to allow attachment of additional hooks or attachment means. The back wall of the interior cavity also provides a location for further hooks and shelving for storage. The device may be provided within the interior of a larger door, or as a door insert adapted to be incorporated into an existing door.

A device for retaining a printed circuit board is provided, which includes a first side plate and two second side plates. The first has at least one first rib perpendicularly protruding therefrom, each of the second side plate has at least one second rib perpendicularly protruding therefrom. The second ribs of the two second side plate are located in a same plane, and the plane that the second ribs of the two second side plates are located is spaced from that the first rib is located. When a printed circuit board (PCB) is placed in the device, the first rib presses against one side surface of the PCB, and the second rib press against the other side surface of the PCB, so that the PCB is retained in the device.

A handheld electronic device including a first body, a second body, a third body, a gear set and a pivot member pivoted on the first body is provided. The second body having a first rack is slidably coupled with the first body. The third body having a second rack is slidably coupled with the pivot member. The gear set is disposed on the first body and coupled with the first rack and the second rack. When the third body shifts a first distance relative to the first body along a first operating direction and drives the gear set, the second body is driven to shift with respect to the first body along a second operating direction opposite to the first operating direction and exposed by the third body. After the second body is exposed by the third body, the third body is tilted with respect to the first body.

The present disclosure relates to a polymer material comprising mesopores extending between melamine-formaldehyde co-polymer nano-particles and wherein micropores extend within the co-polymer nano-particles, methods of producing the same and uses thereof.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.

The invention discloses a kitchen range burner. The kitchen range burner comprises a burner ring body, wherein flame ports are formed inside the burner ring body, a fuel gas cavity is formed in the bottom of the burner ring body, a plurality of cutting grooves are formed in the outer edge of the upper surface of the burner ring body, notches of the cutting grooves are formed in the upper surface and the outer side surface of the burner ring body, the outlet ends of the flame ports are in communication with the cutting grooves, and the inlet ends of the flame ports are in communication with thefuel gas cavity. According to the kitchen range burner, the cutting grooves are formed in the surface of the burner ring body, and the outlet ends of the flame ports are arranged in the cutting grooves, so that the utilization area of the surface of the burner ring body is improved, the amount of the flame ports is increased, and the combustion load of the kitchen range burner is greatly improved; moreover, an overflow groove is formed in an outward inclined angle, so that flow guiding of overflow liquid in the burner ring body is facilitated; blocking eaves of the notches of the cutting grooves can also prevent the overflow liquid from flowing to the vicinity of the flame ports, so that the flame ports is prevented from being blocked; and meanwhile, air channels are matched with a fuel gas channel, so that sufficient combustion of the fuel gas is promoted, and the combustion load of the kitchen range burner is further improved.
