  • Publication number: 20100229853
    Abstract: In certain example embodiments, a solar collector system including a plurality of reflectors is provided. In certain example embodiments, a bracket or pad is bonded to a reflecting panel. The bracket has at least one fastening element protruding therefrom. The fastening element cooperates with at least a hole formed in a mounting frame for securing the panel to a frame, e.g., in mounting the panel. In certain example embodiments, the at least one fastening element comprises two deformable tabs. In certain example embodiments, the at least one fastening element is a shoulder screw that cooperates with a keyhole and slot arrangement provided to the mounting frame, with the shoulder screw being held in place by an optional spring clip.

  • Publication number: 20090101208
    Abstract: In certain example embodiments, a solar collector system including a plurality of reflectors is provided. Each reflector has a stiffening rib associated therewith and is attached thereto on a side facing away from the sun. At least one area on each stiffening rib is suitable for accommodating a polymer-based adhesive for bonding the rib to a side of the associated reflector facing away from the sun. Each stiffening rib is formed so as to substantially match a contour of the associated reflector. At least two of each rib, the associated reflector, and the adhesive have respective coefficients of thermal expansion within about 50% of one another. Each stiffening rib is sized and positioned on the associated reflector so as to increase an EI value thereof at least about 10 times or to at least about 9,180 pascal meters4. Methods of making the same also are provided in certain example embodiments.

  • Publication number: 20070223096
    Abstract: A reflector (e.g., mirror) for use in a solar collector or the like is provided. In certain example embodiments of this invention, a reflector is made by (a) forming a reflective coating on a thin substantially flat glass substrate (the thin glass substrate may or may not be pre-bent prior to the coating being applied thereto), (b) optionally, if the glass substrate in (a) was not prebent, then cold-bending the glass substrate with the reflective coating thereon; and (c) applying a plate or frame member to the thin bent glass substrate with the coating thereon from (a) and/or (b), the plate or frame member (which may be another thicker pre-bent glass sheet, for example) for maintaining the thin glass substrate and coating thereon in a desired bent orientation in a final product which may be used as parabolic trough or dish type reflector in a concentrating solar power apparatus or the like.

  • Publication number: 20070000285
    Abstract: 5 An apparatus and method for bending glass substrate(s) are provided. Microwave radiation is used to heat glass substrate(s) for bending. As a result, a coating supported by the substrate(s) is not heated as much during the bending process compared to if only conventional IR radiation was used. Thus, more extreme degrees of glass bending may be achieved, and/or the likelihood of coating damage reduced.

  • Patent number: 6598426
    Abstract: A method of making a vehicle windshield or other window. An opaque layer (e.g., enamel or water-based) is applied to a glass sheet and then “fired” or cured. The opaque layer is preferably black or dark in color. Thereafter, the sheet with the opaque layer thereon is cut into a desired windshield shape, along a cutting line which extends through both the glass sheet and the opaque layer formed thereon. As a result, on the cut glass sheet the opaque layer extends all the way up to the peripheral edge thereof. In vehicle windshield embodiments, the cut sheet is laminated to another glass sheet via at least a polymer based interlayer in order to form the vehicle windshield.
