Abstract: A flexible multilayer metal structure includes using multiple layers interlocked to form folds holding the layers together. These folds can extend into non-edge portions of the multilayer structure so that the multilayer structure defines air gaps that aid in producing a heat-shielding effect.

Abstract: A rigid structural foil and a method for forming a rigid structural foil is provided. The structural foil includes at least two layers of metal sheets, valley areas and spacers. The metal sheet layers include metal foil having a thickness of 0.006 in. The valley areas are disposed between compressed and uncompressed portions of the structural foil formed during compression of portions of the structural foil. In addition to the valley areas, the structural foil includes spacers. The spacers within the metal sheet layers provide spacing between portions of the metal layers such that the structural foil functions as both a heat shield and an acoustic shield.

Abstract: A fixture for receiving a videotape cassette has a pair of mechanical releases for engaging and operating the mechanical interlocks inhibiting the free access to the videotape contained within therein, thereby exposing a section of videotape and permitting the editing of the tape after being permanently installed within a cassette. A tab having a relatively narrow stem portion and relatively wider base portion includes a releasable dollop of adhesive or double sided adhesive carrier near the stem end and is used in the following method. A new start position for a videotape may be conveniently fixed to eliminate from viewing the otherwise annoying leader material by adhering the tab to the new start position until the tape clears any interfering tension roller, self peeling the tab leaving the exposed adhesive by advancing the tape into the cassette, and wrapping the tape around itself on the wind up spool to adhere two layers of tape together and thereby define the new start position.

Abstract: Multilayer metal foil pads or panels for heat or sound insulation or shielding comprising two or more corrugated metal foil or metal sheet layers wherein a flat metal foil or metal sheet layer is positioned between each pair of corrugated layers. The corrugated layers and/or the flat layers may be embossed, patterned or textured to enhance performance of the pad or panel. A preferred pad or panel comprises an embossed, patterned or textured flat exterior layer adapted for contacting the surface to be insulated or shielded to provide air space between the pad or panel and the surface and to separate the first corrugated layer from the surface. Methods are provided for making the pads and panels, which are useful in automotive applications, food cooking devices and other uses.

Abstract: A forge/swage formed three dimensional multilayer metal foil shield having areas therein where the layers are in a spaced apart relationship, areas therein where the layers are tensioned or stretched, and areas therein where the layers are compressed and interlocked together by folding, rolling, wrinkling, curling, coiling, crimping and the like. The multilayer metal foil shield is formed by forge/swage shaping in an appropriate mold apparatus a preform of a stack of metal foil layers having gaps between the layers. The gaps are provided by embossments in the layers or by spacers between the layers. The forge formed multilayer metal foil shields have utility as heat shields and acoustic shields, particularly on vehicles. The forge formed multilayer metal foil shields are mounted on automobile underbody areas, such as the bottom of the floor pan of the passenger compartment, to provide heat and sound insulation. Other automotive uses include fire wall, exhaust tunnel, motor mount and exhaust down pipe.

Abstract: A flexible corrugated multilayer metal foil structure comprising a stack of metal foil layers which are formed in corrugations extending across a stack of the metal foil layers, wherein all of the layers have the same corrugated pattern and shape as a result of the stack being shaped in corrugations or the layers being separately shaped in corrugations then nested into a stack. A portion of the corrugations of the stack of metal foil layers can be compressed to fold the layers together whereby the layers are interlocked together in overlapping relationship.
