    Abstract: Multiple-component fertilizer materials and methods of use are provided, wherein the fertilizer materials include first and second fertilizer products respectively including an ammoniacal fertilizer (e.g., urea) in combination with a partial calcium salt of a selected copolymer, and a phosphorous fertilizer (e.g., DAP) in combination with a partial sodium salt of a selected copolymer. The copolymer fractions of the first and second fertilizer products are most preferably copolymers of itaconic acid and maleic anhydride. The fertilizer materials give synergistically enhanced crop yields when applied to soil or growing plants.

    Abstract: This invention relates to a circuit arrangement and the associated mechanism for slaving the angles of rotation of the slats of a plurality of centrally controlled sun or window blinds. The driving motor of each blind is provided with current via a corresponding operational amplifier and related circuit. The motor operates the slats to achieve balance between an input control voltage and a voltage depending on the angular position of the slats. An automatic version in which the control voltage is generated by a photoelectric sensor and several circuit variations are shown.
