    Abstract: The invention relates to a method of processing the waste sludge obtained in purification facilities for phosphoric acid produced by the wet process. The composition of this sludge is such that it cannot be utilized for any purpose in this state. It is known that sludge from wet phosphoric acid purification facilities contains different quantities of certain substances, the concentrations being such that these substances may not be allowed to mix with surface water or ground water under any circumstances, not even in the case of dumps. A typical composition of such waste sludge is as follows:______________________________________ Fe 9.0% by weight P.sub.2 O.sub.5 21.0% by weight CaO 6.2% by weight SiO.sub.2 12.5% by weight MgO 5.8% by weight Al.sub.2 O.sub.3 2.7% by weight Cr.sub.2 O.sub.3 0.7% by weight V.sub.2 O.sub.5 0.6% by weight Na.sub.2 O 18.0% by weight K.sub.2 O 0.3% by weight F 1.7% by weight C 2.5% by weight S 0.3% by weight Remainder* 18.7% by weight 100.0% by weight ______________________________________ *The remainder consists mainly of hydration water and carbonate that did not decompose at a temperature of 105.degree.

    Abstract: An horticultural blend is disclosed. The horticultural blend includes coal refuse and slag blended with at least a portion of the coal refuse. The coal refuse has a particle size, the particle size corresponding with all material in the coal refuse having a maximum dimension of less than about 2 inches and at least about 25% of the material in the coal refuse being capable of passing through a standard number 4 sieve. The horticultural blend has a pH within a range of about 3.5 and about 10 and the horticultural blend facilitates growth of vegetation when applied to a coal refuse pile at a thickness of less than about 2 feet.

    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: A control system for a cyclic process includes a pulse generator incorporating three rotatable gears for generating pulses. A first gear having n ferromagnetic teeth is mounted on a main generator shaft for generating a train of pulses in a magnetic perception head upon rotation of the main generator shaft, and also mounted on the main generator shaft is a second gear wheel having n + 1 teeth. The second gear wheel drivingly engages with a third gear wheel having n teeth which is mounted for rotation on another shaft, and the second and third gear wheels each carry a ferromagnetic element movement of which past respective further magnetic perception heads causes the generation of a single pulse during each rotation of the second and third gear wheels. The train of pulses is used for driving a counter to control the sequential operations of the cyclic process, and a coincidence between the pulses generated by the second and third gear wheels is used to reset the counter and initiate a succeeding cycle of the process.
