Abstract: A device carrier for carrying an electronic device includes a pouch having a rear wall and a pair of straps. Each strap has a first end, a second end and a side. The first ends of the straps are coupled with the rear wall at a distance from one another. Each strap further includes a first section of hook and loop fastening material coupled with the side and proximate to the second end. Each strap also has a second section of complimentary hook and loop fastening material coupled with the side and located between the second end and the first section of hook and loop material. Further, each strap has a buckle coupled with the rear wall. Each strap is secured to the corresponding buckle by placing the second end through the buckle and looping the first end over onto itself so that the first and second sections of hook and loop fastening material are directed toward one another and coupled together.

Abstract: A building panel constructed of a gypsum-cement-catalyst formulation molded in layers and including a rigid stud framework. The layers include surface layers, a fire resistant layer and an insulating layer, as well as reinforcement and building paper. A modified panel is molded in layers with structural strength provided by a grid providing spaced apart wire panels. The panel is constructed by a method that includes applying a fluid material of gypsum and cement into a mold having a removable base. Reinforcing mesh and a rigid framework are inserted into the mold along with building paper and reinforcement which are secured to the framework. Additional gypsum and cement are then applied to cover the framework after setting. The base is removed and the initial layer of gypsum and cement is mechanically fastened to the framework.

Abstract: A novel filtration device having a substantially rigid frame comprised of an outer peripheral band connected by a plurality of spacers to an inner breather tube, wherein filter pads are secured over both sides of the frame and separated by the spacers to form an enclosed central air pocket accessible only through the breather tube. The breather tube is adapted to be detachably connected to an inlet port in a respirator face mask so as to provide a closed channel for air flow from the central air pocket to the interior of the face mask.
