Abstract: A mixing system for a fluid tank is described, the system having a drive motor, an impeller, a shroud enclosing the impeller and a cutter mounted on the shroud to cut solids. The shroud is open at inlet and discharge ends for drawing in and discharging fluid from the tank. A recess is provided on the internal surface of the shroud, wherein the cutter is adjustably positioned within the recess. The cutter is detachable from the recess to allow replacement. In use, homogeneity is maintained in a slurry contained within the tank by submerging the impeller such that the cutter cooperates with the impeller to cut solids within the slurry, drawing tank contents into the impeller at the inlet, cutting material between the cutter and blade, and then discharging the material.

Abstract: Disclosed herein is a method for manufacturing a solar cell. The method includes the following steps. A substrate is provided. An article having a plurality of protrusions touches the surface of the substrate and thereby forming a plurality of indentations thereon. Subsequently, a transparent conductive layer is formed on the indented surface of the substrate, a photovoltaic layer is formed on the transparent conductive layer, and then a back electrode is form above the photovoltaic layer.

Abstract: A photovoltaic module includes a photovoltaic panel and a frame securing to an edge of the photovoltaic panel. The frame includes a metal portion and a composite material of a plastic material and glass fibers or of a silicone resin and glass fibers. The composite material is integrated with the metal portion to form a unitary frame.

Abstract: A mixing system for a fluid tank is described herein, the system having a drive motor, an impeller capable of being submersed, a shroud having a sidewall enclosing the impeller, and a cutter mounted on the shroud and cooperating with a blade of the impeller to cut solids within the shroud. The shroud is open at both an inlet end and a discharge end for drawing in and discharging fluid from the tank. A recess is provided on the internal surface of the shroud, wherein the cutter is adjustably positioned within the recess. Additionally, the cutter is also detachable from the recess so that it may be replaced when worn.

Abstract: A solar panel module includes a solar panel, a generally rectangular frame, a pair of bridge members and a beam. The solar panel has a light-receiving surface and a back surface on two opposite sides thereof. The generally rectangular frame is attached to all edges of the solar panel. The pair of bridge members are secured to a pair of parallel edges of the generally rectangular frame on the back surface of the solar panel. The beam is interconnected between the pair of bridge members, wherein each bridge member has a wider width than a width of the beam.

Abstract: A photovoltaic assembly includes a photovoltaic panel, two curtains and two rollers. The photovoltaic panel is for converting light into electricity and comprising two opposite surfaces. Two curtains are for absorbing solar heat to roast the photovoltaic panel when the two curtains are disposed to cover the two opposite surfaces of the photovoltaic panel. Each of the two curtains includes a stack of a reflective layer, a high thermal capacity layer and a transparent layer. The high thermal capacity layer is sandwiched between the reflective layer and the transparent layer. The reflective layer is closer to the photovoltaic panel than the high thermal capacity layer and the transparent layer are when the two curtains cover the two opposite surfaces of the photovoltaic panel. Each roller includes a rotatable shaft for rolling each of the two curtains.

Abstract: A photovoltaic panel assembly includes a photovoltaic panel of two opposite surfaces. A photovoltaic array is disposed on one of the two opposite surfaces. The heat sink is disposed over the other of the two opposite surfaces, wherein the heat sink comprises a wavy cross-section.

Abstract: The present description discusses apparatus and methods for applying straps around a bundle of objects by applying a variable force to tension the strap around the bundle of objects and then actuating a series of cams to control the sealing of the strap around the bundle of objects. The strap is bonded together by the insertion of a heating element between the strap ends to activate the adhesive thereon. The strapping machine for accomplishing the above method is configured with a feed and tension unit configured to provide a simplified “V-shaped” strap path that reduces bending of the strap, reduces friction on the strap, and minimizes other strap feeding difficulties. The machine is further comprised of a track assembly configured with a track channel having a plurality of biased covers. The covers are biased in a closed position until tension is applied to the strap, which forces the covers to pivot open and release the strap around the bundle of objects.
