Abstract: A photovoltaic module assembly includes a photovoltaic module and a base layer. The photovoltaic module has a bottom side, a top side, a main body, and a peripheral edge strip. The peripheral edge strip includes a plurality of apertures formed therethrough. The base layer is disposed adjacent the bottom side of the photovoltaic module. The base layer has an underlying portion and a flap portion. The flap portion is folded over the peripheral edge strip of the photovoltaic module, and is disposed adjacent the top side of the photovoltaic module. The flap portion is attached to the underlying portion of the base layer through the plurality of apertures in the peripheral edge strip. The photovoltaic module is thereby secured to the base layer.

Abstract: Apparatus for cleaning particulate material including coal particles and dust from a flexible belt of the type which is adapted to transport material such as coal on its material-supporting surface and which is of a composition which has and is subject to the development of surface cracks. The belt is advanced lengthwise along a predetermined path on its return run with the material-supporting surface on the underside. A scraper blade is supported crosswise of the belt in scraping contact with the material-supporting surface of the belt as the belt is advanced. Liquid is sprayed against the material-supporting surface of the belt and into the surface cracks adjacent to the point of contact of the scraping edge. The liquid is sprayed against a surface of the blade to be deflected into the cracks and also to maintain the blade in a clean condition. A backing member holds the belt down in contact with the scraper blade.
