    • This invention presents a robust and low cost design for a sun tracking, solar panel mounting system that can be mounted on a wide range of light poles and power poles. This design incorporates a structural base that is attached to the pole with separate “U” bolts and custom cradles that precisely accommodate the mounting pole dimensions. The structural base incorporates an axle and separate pivoting frame to hold the solar panel and allow it to rotate about the axle in a celestial tracking configuration known as an equatorial mount. A simple automotive style electric motor in the support arm interfaces with a curved gear rack of the pivoting frame to power the motion of the solar panel and frame. A control system coordinates the movement of the frame to achieve the sun tracking.
    • 本发明提出了用于太阳跟踪的太阳能面板安装系统的鲁棒且低成本的设计,其可以安装在宽范围的灯杆和电源杆上。 该设计结合了一个结构基座,该基座用独立的“U”螺栓和定制的支架连接到极柱,可以精确地适应安装极尺寸。 结构基座包括一个轴和独立的枢转框架,用于固定太阳能电池板,并允许其在被称为赤道仪的天体跟踪结构中绕轴旋转。 支撑臂中的简单的汽车式电动马达与枢转框架的弯曲齿轮架接合,为太阳能电池板和框架的运动提供动力。 控制系统协调框架的运动以实现太阳跟踪。

    • According to the present invention, curable compositions comprising (i) one or more polyacid containing at least two carboxylic acid groups, anhydride groups, or salts thereof; (ii), optionally, one or more polyol containing at least two hydroxyl groups; and (iii) one or more reactive β-hydroxyamide group containing polyol, which is the reaction product of a lactone or cyclic ester and an alkanolamine, of the following formula (I): in which, R and R″ independently represent H, or any monovalent C1 to C18 linear or branched alkyl radical, which radical may comprise one or two aryl or cycloalkyl group, one or more hydroxyl, amine, thiol, amide, carboxyl or alkenyl group, or combinations thereof; R′ represents either a covalent bond or a divalent C1 to C5 alkylene radical where the alkylene radical may bear alkyl group substituents; y is the integer 1 or 2; x is 0 or 1, such that (x+y)=2; wherein the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of said hydroxyl groups is from 1/0.01 to 1/3. The curable compositions of the present invention provide less corrosive, low energy curing binders. Further, the present invention provides methods to use the compositions as aqueous binders for composites, nonwoven and woven substrates, and the products produced thereby.
