Abstract: Processes for forming an enhanced material or structure are disclosed. The structure typically includes a preform that has a first common surface and a recess below the first common surface. A filler is added to the recess and seams are friction stir welded, and materials may be stir mixed.

Abstract: A semiconductor substrate for a micro-fluid ejection device. The substrate includes plurality of micro-fluid ejection actuators disposed adjacent a fluid supply slot in the semiconductor substrate. A plurality of power transistors, occupying a power transistor active area of the substrate, are disposed adjacent the ejection actuators and are connected through a first metal conductor layer to the ejection actuators. An array of logic circuits, occupying a logic circuit area of the substrate, is disposed adjacent the plurality of power transistors and is connected through a polysilicon conductor layer to the power transistors. A power conductor and a ground conductor for the ejection actuators is routed in a second metal conductor layer. The power conductor overlaps at least a portion of the power transistor active area of the substrate and the ground conductor overlaps at least a portion of the logic circuit area of the substrate.

Abstract: A shoe with improved lacing means includes a shoe, shoe laces (14) and a hook and loop element pouch (10). On the underside, the side making contact with the shoe, are two openings (16) that are used to slide the shoelaces through. With the pouch (10) open, the shoelaces (14) are pushed through the holes (16), pulled firmly and then tied as usual. Place the tied shoelaces (14) down into the pouch (10). There is a hook and loop element strip (22) on the opening making it easy to close, while keeping laces (14) secure. The pouch (10) can be attached to the shoe by hook and loop element strips (18) on both the right and left underside of the pouch (10). The pouch (10) will keep the shoelaces (14) from loosening, snagging and untying.

Abstract: Stiffness improvements for multi-ply paperboard laid from chemically pulped softwood and hardwood papermaking furnish are obtained by fiber fractionating the softwood pulp and repositioning the resulting fractions. Chemically pulped and preferably bleached softwood fiber "rejects" of a fractionation screen are redistributed into the outer plies of a three-ply, 300-350 g/m (approximately 195 #/3,000 ft.) basis weight paperboard. The fractionation "accepts" are repositioned to the center ply for a 12% to 15% increase in Taber stiffness. The short, "accept" fiber from the fractionation screen is mixed with chemically pulped hardwood fiber or modified mechanical pulp of either species for formation of the center ply on a multiformer paper machine.

Abstract: The specification describes a system for the thermal treatment of energetic materials which generate a tremendous volume of gaseous products upon combustion. The system includes a containment system which maintains an interface between hot exhaust gas products and a cooler gas, yet allows the relatively slow removal and treatment of the exhaust gas products from the containment system while permitting the inflow of gas into the containment system to replace an equivalent volume of exhaust gas products removed therefrom.

Abstract: This invention provides a combination of ground position indicator and aircraft signaling devices for airborne personnel. The disclosed position indicator and signaling devices include a substantially pliable mesh web for deployment upon the ground, the web having a directional indicator and a color or other devices for contrast between the web and the ground so that the web is highly visible to airborne personnel who are in an overhead position adjacent to the ground upon which the web is deployed.
