Abstract: A load structure may include a panel, a layer of fibrous material, and/or an over mold coating. The panel may include a core. The layer of fibrous material may be disposed on a first side of the panel and an edge of the panel. The over mold coating may be disposed on a second side of the panel.

Abstract: A load structure may include a panel having a core, and a coating of polyurethane around the core. The load structure may also have a layer of carpet or felt on at least a portion of a first side of the panel. The load structure may further include an over mold coating on a second side of the panel.

Abstract: A method of manufacturing a load structure may include first forming a panel having a first side and a second side. The method may then include trimming the panel, including clearing a fill passage through the panel from the first side to the second side. The method may then include applying an over rim coating on the second side of the panel via an over rim tool by which a resin may be injected through the fill passage to the second side. The method may further include performing final trimming of the panel, and finally performing final assembly to form the load structure.

Abstract: Embodiments provide systems and methods for taking power from an electric power grid and converting it into higher-pressure natural gas for temporary storage. After temporary storage, the higher-pressure natural gas may be expanded through an expansion engine to drive a generator that converts energy from the expanding natural gas into electrical power, which may then be returned to the electric power grid. In this way, the disclosed systems and methods may provide ways to temporarily store, and then return stored power from the electric power grid. Preferably, the components of the system are co-located at the same natural gas storage facility. This allows natural gas storage, electrical energy storage, and electrical energy generation to take place at the same facility.

Abstract: Embodiments of the invention include multi-functional power supply devices and related methods. In an embodiment, the multi-functional power supply device can include a base monument and a detachable accessory module. The base monument can include a first housing, an integrated power and support socket, an internal circuitry, AC electrical outlets, and DC electrical outlets. The detachable accessory module can include a second housing and an integrated power and support plug. The detachable accessory module can be configured to fit on top of the base monument. Other embodiments are also included herein.

Abstract: Reformation of a round tube to a tube with a selected polygonal segment is achieved by supporting the round tube on a mandrel having rounded corners that mate with the tube's inside diameter. The mandrel is otherwise provided in the resultant polygonal shape. The supported tube is subjected to the compressive force of a die having upper and lower die sections that define an elongated polygonal cavity. The planar sides of the cavity are offset relative to the parting line. Preferably, the corners of the cavity adjacent the parting line are wrapped by a leg of the die section. Upon closure of the die sections, the tube material is allocated to a particular quadrant by contact with the die section and the tube is reformed. Excess material that may result from tolerance permitted variations is delivered to the corners of the polygonal tube section maintaining uniform wall thickness across the flat sides of the reformed tube.
