Abstract: A method for forming a clad structure utilizing a moving resistance energy source. The method forms a metallurgical bond between a cladding layer and a primary layer such that at least 2% of a cladding layer surface is metallurgically fusion bonded to a primary layer surface. The fusion bond does not extend all the way through the primary layer or the cladding layer. Either, or both, of the layers may incorporate surface texturing to reduce the contact area between the layers, and melting point suppressants may be incorporated into the method.

Abstract: A method of preparing a particulate material comprising the steps of adding silicic acid solution, optionally doped with aluminum, optionally added to a slurry of pre-existing nanoparticles at a neutral to slightly acidic pH of no more than seven, and at a temperature of about 20° to 30° C. This yields a polysilicate particulate dispersion. Then, the pH of the dispersion is raised to greater than seven, to stabilize/reinforce particles of the particulate dispersion. Optionally, the particles may be dried, and have increased porosity and surface area.

Abstract: A D-ring of metal wire is specially shaped to accept and retain a special grommet of a hard, wear-resistant polymeric material. The D-ring has a base leg, a pair of side legs joined to opposite ends of the base leg and converging toward each other from junctures with the base leg, and a substantially arcuate head joined to the side legs at junctures forming a neck opening that is constricted relative to a head opening defined within the head. The grommet is received within the head opening and neck opening of the D-ring and has a hole adapted to receive a hook and a peripheral groove that is in captured engagement with the head of the D-ring and with the junctures of the head and the leg portions. Portions of the groove located at the neck opening of the D-ring are deepened relative to adjacent portions of the groove within the head opening so as to retain the grommet while enabling the grommet to be pressed endwise through the neck opening and into the head opening of the D-ring.

Abstract: A method for repairing defects in a substrate comprising the steps of placing a consumable filler slug in contact with the substrate in the vicinity of the defect; placing at least one electrically conductive cover sheet in contact with a portion of the consumable filler slug; bringing a first electrode and a second electrode in contact with the at least one cover sheet and applying a force; and transmitting electrical current between the electrodes, thereby resistively heating the at least one cover sheet and conductively heating the consumable slug and a portion of the substrate resulting in coalescence in a substantially liquid pool that fills the defect. The pool is then cooled to solidification under pressure. Alternative embodiments eliminate the need for the conductive cover sheet(s) by utilizing electrodes having increased electrical and thermal resistance. The consumable slug may be formed as a single unit or multiple sections, and may incorporate sacrificial retainers.

Abstract: An item of expandable luggage includes a substantially rigid main peripheral frame and a substantially rigid secondary peripheral frame. A peripherally continuous gusset of flexible material is connected between the two peripheral frames. Opposite wall panels of the main peripheral frame are joined to corresponding opposite wall panels of the secondary peripheral frame by bridge assemblies, one such assembly being associated with each of the opposite wall panels of the respective frames. Each bridge assembly includes a pair of parallel spaced-apart slide rails affixed to the wall panel of the main peripheral frame, a substantially rigid bridge plate affixed to the wall panel of the secondary peripheral frame and slidably received by the slide rails, and a releasable latch that couples the bridge plate to the wall panel of the main peripheral frame in at least one position in which the secondary peripheral frame is held securely in a position spaced apart from the main peripheral frame.
