Abstract: A solar panel system includes a plurality of solar modules that produce DC electrical energy when exposed to sunlight. Each of the solar modules includes a frame, a photovoltaic panel mounted to the frame, and an electrical coupling for outputting the DC electrical energy from the photovoltaic panel. The solar modules are mounted to the deck of a roof having a ridge and a ridge vent extending at least partially along and covering the ridge of the roof. One or more micro-inverters is located beneath the ridge vent and each is electrically connected to a bank of two or more solar modules selected from the plurality of solar modules. The micro-inverters on the roof convert the DC electrical energy produced by the photovoltaic panels to AC electrical energy, and the AC electrical energy is aggregated from the micro-inverters and delivered to a remote electrical system.

Abstract: A solar module for a roof covering system that generates electrical power from sunlight includes a frame having a bottom surface supported on a deck of a roof, a top surface, and a thickness between the bottom surface and the top surface. The solar module also includes a solar element mounted to the top surface of the frame which has an upper surface. a micro-inverter mounted to the top surface of the frame and to the side of the solar element, and a raised access panel that is removably coupled to the frame to surround the micro-inverter. The raised access panel has an access panel top surface that is elevated above the upper surface of the solar element. The top surface of the frame forms a water shedding surface below the micro-inverter for directing water away from the roof.

Abstract: The present application provides a napkin dispenser for dispensing a number of folded napkins from a sheet material to an end user. The napkin dispenser may include a loading station for loading the sheet material, a folding station for folding a napkin from the sheet material, and a presentation station for presenting one or more of the folded napkins to the end user.

Abstract: A dispenser for viscous liquids effectuates sequential operations by hydrostatic pressure on an assembly of two pistons separated from each other in a cylinder by a separation spring. When the piston assembly is embedded in material to be dispensed, the space between the pistons fills with material to be dispensed. Pressuring the reservoir by squeezing it or by the addition of pressurized gas, forces the piston assembly down the cylinder at the end of which is an opening from which material in the piston assembly can escape. One of the pistons moves toward the other end by pressure from the reservoir, causing material in the piston assembly to be dispensed. The volume inside the piston assembly defines and limits the volume of material that can be dispensed.

Abstract: An electrically powered dispenser for paper towels uses a special roller bracket to provide not only proper positioning and support for the drive and pinch roller shafts, but also tension and grounding between the drive and pinch rollers, thereby producing a dispenser that is both reliable to operate and simple to assemble. The mounting bracket is integrally formed from a single sheet of conductive material and preferably includes a pair of side plates connected by a mounting bar which includes an integrally formed tear bar portion for cutting the material after it has been transported past the rollers. Each side plate incorporates a flexible bridge (arm) portion for biasing each of the two shafts against a respective bearing portion to thereby complete a static discharge path from the rollers to the mounting bar without requiring any separate springs, contacts or wires.

Abstract: An open flow fluid filter has a pleated main filter element having a plurality of pleats in a closed loop having an outer perimeter defined by a plurality of outer pleat tips, and an inner perimeter defined by a plurality of inner pleat tips. The loop has a hollow interior extending along an axis. Fluid to be filtered flows through the main filter element from an upstream dirty side to a downstream clean side, and flows axially in the hollow interior. The main filter element has an axial flow passage extending along the axis and circumscribing the hollow interior and has a flow perimeter greater than the inner perimeter. A safety filter element downstream of the main filter element filters both the axial flow in the hollow interior and additional flow between the flow perimeter and the inner perimeter. A filter with additional flow is also provided.

First and second end caps at distally opposite axial ends of the liner and sleeve each have a central aperture, the aperture in the first end cap providing air flow therethrough in communication with the hollow interior of the liner, the aperture in the second end cap retaining a closing cover. The cylindrical filter media sleeve extends axially along the inner liner and is axially retained between the cover and the first end cap. The cover is removably mounted to the second end cap in snap-in relation and axially retains the sleeve on the inner liner.
