Filed: 1930-10-02
Abstract: A fertilizer containing potassium sulphate and mono-, di-, or tricalcium phosphate is obtained by heating potassium chloride with phosphoric acid and calcium sulphate at say 500-800 DEG  C., preferably in a current of steam.  Hydrochloric acid is evolved. The phosphoric acid may wholly or in part be replaced by its ammonium salts, or ammonia may be passed into the reaction mixture, whereby ammonium chloride is evolved.  Temperatures from 200-350 DEG  C. are employed in this method.  By suitably regulating the proportions of the reagents, an ammonium calcium phosphate is formed.  The product may be admixed with substances such as urea, ammonium sulphate-nitrate, ammonium nitrate or phosphate or calcium nitrate. Alternatively, it may be lixiviated and potassium sulphate crystallized; the residue of tricalcium phosphate may be dissolved in the hydrochloric acid evolved.  When however the products containing mono- and dicalcium phosphate respectively are leached, potassium phosphate and potassium phosphate and sulphate respectively are produced.  Potassium phosphate may be recovered in the solid state.ALSO:A fertilizer containing mono-, di- or tricalcium phosphate or in some cases, ammonium calcium phosphate, and potassium sulphate is obtained by heating potassium chloride with calcium sulphate and phosphoric acid.  Ammonia may be passed into the mixture, or ammonium phosphate may be added.

Abstract: 468,116. Automatic control systems. ISMAY DIRKS APPLIANCES, Ltd. (Dirks, R.) Nov. 3, 1936, No. 29950. [Class 38 (iv)] Humidity, &c.-The moisture-content, calender pressure, or other quality which influences the electrostatic charge imparted to a cellulosic or like material 5 by friction in a machine working upon it is regulated by an electroscope 1 adapted to control a reversing switch D in the circuit of an electric motor 25 adjusting, for example, a resistance R controlling the speed of a motor 30 driving the machine. Manual control of the motor 25 may also be obtained by additional switches 17, 23. Where the material is being dried in a steam &c. heated chamber 8 a valve 11 controlling the supply of steam may be alternatively or additionally controlled. Where the material may be damaged by excessive speed a centrifugal switch actuated by the driving motor 30 may actuate a change over switch to connect the electroscope control to a motor controlling the steam valve at maximum speed. This valve may have means to restore control to the driving motor when a given maximum valve opening is attained. Hunting of the control due to the distance between the drier 8 and the charge collecting brushes 4 may be avoided by intermittent opening of the circuit of the adjusting motor, or by reversing it for a short time after each adjustment, these operations being effected by automatically actuated electric switches. Specification 391,986, [Group XXXVI], is referred to.
