Title: Two-way two-position electrically controlled valve
IPC: B60T8/36
Filed: 1971-07-21
Abstract: 1322107 Valves FIAT SpA 21 July 1971 [26 Feb 1971] 34235/71 Heading F2V In a normally-open valve a plunger 144 of a solenoid 146 is normally biased upwards by a tension spring 145 but on energization of the solenoid moves downwards to abut a diaphragm closure member 126 and move it against a seat 120 between an inlet 112 and an outlet 114. Simultaneously, a spring-loaded disc 154 closes a bore 142 through the diaphragm which also has a restriction 140 therethrough. When the plunger is in the normal upper position, flow through the valve can take place in either direction since P.T.F.E. ball 15 prevents flow from the outlet to the inlet from causing a pressure build-up above the diaphragm which would close the valve. The valve may be normally-closed.

Title: Improvements in or relating to the production of potassium sulphate or mixed crystals of potassium sulphate and ammonium sulphate
IPC: C01D5/08
Filed: 1932-12-08
Abstract: A multistage process for the production of potassium sulphate or mixed crystals of potassium sulphate and ammonium sulphate comprises reacting ammonium sulphate with an aqueous liquor containing potassium chloride to yield an intermediate solid complex of potassium sulphate and ammonium sulphate, separating the complex from the mother liquor and reaching it with or without more ammonium sulphate, with an aqueous liquor to give a second intermediate solid complex which is richer in potassium sulphate than the first complex. The total quantity of ammonium sulphate used is in substantial excess over the total potassium chloride employed in all stages.  In a cyclic form of the process, the complex produced in each stage (r) from the first to penultimate is reacted in the following stage (r + 1) with the mother liquor produced in the corresponding next following stage (r + 2) of a previous cycle, or with potassium chloride and water in the case of the final stage, the total potassium chloride and/or water being preferably divided up into portions which are added at each stage.  Each stage may be carried out at the same temperature or the temperature may be diminished in successive stages starting from the stage employing pure ammonium sulphate.  The excess of ammonium sulphate may be recovered by working up the liquor from the first stage.  The liquor may be evaporated to deposit ammonium sulphate or potassium ammonium sulphate at elevated temperature and finally cooled to separate ammonium chloride and p  leave a liquor of the same composition as, but less in quantity than, the original liquor from the first stage. According to the examples, (1) a three stage process at 30 DEG  C. produces potassium sulphate with a 90 per cent yield; (2) a four stage process at 30 DEG  C. produces potassium sulphate with a 94 per cent yield; (3) a three-stage process at temperature of 90 DEG  C., 80 DEG  C. and 30 DEG  C. in succeeding stages produces potassium sulphate.
