Title: Nitric acid digestion of phosphates
IPC: C01F11/44
Filed: 1968-01-05
Abstract: Ca(NO 3 ) 2 crystals are obtained by digesting natural Ca phosphate with HNO 3 , initiating crystallization of Ca(NO 3 ) 2 at 18-26 C. in the presence of seed crystals, allowing the crystals to grow, separating off large crystals, separating small crystals from the mother liquor (optionally after a further crystallization) and recycling the small crystals as seeds. In Fig. 2, phosphate and HNO 3 are digested at 40-45 C. in vessel 1. The solution is passed to germination tank 7 maintained at 18-26 C. by cooling coil 8 supplied with water cooled at 9 by evaporation of liquid NH 3 from 10. The solution is then passed to growth tank 11 maintained at 8-16 C., large crystals are separated at 13 at 8-16 C., and the mother liquor and small crystals are passed to tank 18 maintained at - 2 to +8 C. for further crystallization. The suspension is separated at - 2 to +8 C. in decanter 15 and small crystals are fed into tank 7. Cooling fluid circulates in coils 12 and 19 and refrigeration unit 20. Mother liquor from 15 is saturated in tank 17 with NH 3 from 9. In Fig. 1 (not shown), tank 18 is absent, the suspension of mother liquor and small crystals from 13 is passed directly to decanter 15, and cooling coil 12 is supplied with NH 3 from 10 which is then combined with NH 3 from 9. Tank 7, separator 13, and decanter 15 are then all operated at 12-20 C.

Title: Burner fuel supply control signal generating device
IPC: F23N5/12
Filed: 1974-06-28
Abstract: The device comprises flame detection means and a generating circuit adapted to deliver a signal when a flame signal, generated by the flame detection means, is applied to one of its inputs.
