Various embodiments provide methods in which a metal matrix composite (MMC) material is incorporated into a metallic structure during a one-step near-net-shape structural forming process. Various embodiments provide in-situ selective reinforcement processes in which the MMC may be pre-placed on a forming tool in locations that correspond to specific regions in the metallic structure. Various embodiment near-net-shape structural forming processes may then be executed and result in various embodiment metallic structural components with selectively-reinforced regions that provide enhanced mechanical properties in key locations.

Decking with a panel of uniform thickness sheet metal has a repeating pattern of top flanges and bottom flanges connected by webs therebetween. At least one flange is made up of a plurality of folded-layer segments adjacent to each other in a stacked position to increase the thickness of the flange. Additionally a structural member extending along a longitudinal axis has a uniform thickness plate folded back onto itself about the longitudinal axis or an axis parallel to the longitudinal axis to increase the thickness and provide greater resistance to buckling in response to compressive forces. Such structural members not only provides certain structural advantages but also may provide an aesthetically pleasing appearance.

A conduit (100) for transporting a fluid comprises a first collar (102), a second collar (103), and a bellows (108). The bellows (108) comprises a corrugated inboard ply (110), a corrugated outboard ply (112), and an interstitial space (126), interposed between the corrugated inboard ply (110) and the corrugated outboard ply (112). The conduit additionally comprises a second weld (138), hermetically coupling the corrugated inboard ply (110) and a first outer collar portion (104), a third weld (134), hermetically coupling the corrugated outboard ply (112) and a first inner collar portion (106), a fourth weld (186), hermetically coupling the corrugated inboard ply (110) and a second outer collar portion (105), a fifth weld (184), hermetically coupling the corrugated outboard ply (112) and a second inner collar portion (107), and a first sensor (116), communicatively coupled with the interstitial space (126).

The conceived invention provides both a film applicator and a method for placing a continuous film sleeve around a hose, or a grouping of a plurality of hoses. The sleeve thickness is approximately mil to 20 mils thick, which is suitable for cleanliness protection and reducing the possibility of ripping when the hoses are dragged across a floor. The embodied invention includes a plastic sleeve payout tube, that surrounds and encompasses the hose/hoses. The hoses are routed through the sleeve payout tube when they are hauled into a building to be cleaned. The payout tube stores a compacted length of an enclosing plastic sleeve, and the sleeve pays off as the hoses are dragged into the facility to be cleaned. The initial attachment of the plastic sleeve and hoses is by use of an adhesive tape or an outer clamping strap.

A system comprising a protective jacket for insulating pipe is provided. The protective jacket comprises a first metal shell comprising an interior surface and an exterior surface, wherein the interior surface comprises a moisture protective coating, and the exterior surface comprises a film adhered to the exterior surface by an adhesive, and wherein the adhesive provides for a toolless removal of the film.

A bowl forming device may include a mandrel sleeve, a stem mandrel, and a bowl mandrel. The mandrel sleeve may comprise a stem cavity, a bowl mating surface, and a sleeve surface. The stem mandrel may comprise a stem surface and a neck. The bowl mandrel may comprise a neck mating surface and a bowl surface. The device may be transitioned into and out of a nested position, in which the bowl mandrel may be mated with both the mandrel sleeve and the stem mandrel so that the stem mandrel may be received within the stem cavity and the sleeve mating surface contacts the bowl mating surface, to facilitate travel and storage of the device. A method of forming a smoking bowl using a bowl forming device is provided which includes the steps of forming a sheet of malleable material against the mandrel sleeve, stem mandrel, and bowl mandrel.
