Filed: 1917-10-10
Abstract: 121,305. Illingworth, W. H. Oct. 10, 1917. Mercury cut-outs.-The upper end of the column is arranged in open communication with the atmosphere and with a well so placed that, when the column parts, the whole of the mercury above the gas is thrown over into the well and the gas escapes freely to the atmosphere. In the form shown in Fig. 1, the porcelain carrier B contains a detachable core E having a central passage narrowing towards the middle of the core to contain the mercury &c. The carrier is fitted with end caps b, b<1> containing spring-pressed plunger contacts C, C<1> contacting with the mercury at the ends of the passage and fitting in sockets c, c<1>, from which the blades c<3>, c<4> project. The upper contact is cut away slightly to form a passage between the column of mercury and a well D in the carrier. With currents above a certain maximum, determined by the cross-sectional area of the mercury column at its narrowest part, the column separates at its midway point, and a portion of it is discharged into the well, any gases produced being discharged through vent passages d. To reset the cut-out, it is tilted into the horizontal position about the hinged connexion between the blade c<4> and the fixed contact c<6>, whereupon the mercury from the well fills up the column. To ensure that the mercury passes into the core passage, a piston F on a plunger f<2> may be employed to force the mercury into place after the carrier has been tilted. The plunger may be mounted in the bottom contact. The rise in the surface of the mercury in the well when the cut-out has operated may lift a float D, Fig. 13, carrying a framework with a pivoted indicator G, which is tilted into the raised position when the cut-out operates. An indicating-device may be operated by the discharged gases. For cut-outs of high capacity, a core with a number of passages e<3>, Fig. 11, communicating with one another at one end and arranged. so that the columns are in parallel in the circuit, is employed.

Title: Improvements in or relating to alkali metal bichromate purification
IPC: C01G37/14
Filed: 1959-04-30
Abstract: <PICT:0859264/III/1> Sulphate impurities are removed from alkali metal bichromate solution by adding an alkaline earth metal dichromate solution to provide an alkaline earth metal/sulphate ratio of at least 1:1, and filtering off the precipitated alkaline earth metal sulphate thus formed.  The alkali metal bichromate solution to be treated is first concentrated to about 60 DEG  Baum<\>ae, to crystallize out at least a part of the sulphate impurities. Alternatively the alkaline earth metal dichromate may be formed in situ by adding chromic acid and an alkaline earth metal carbonate or oxide to the alkali metal bichromate solution.  Thus a chrome ore, mixed with sodium carbonate and lime may be roasted in a rotary kiln at 2000 to 2200 DEG F., cooled and leached to form a raw liquor containing for example sodium chromate, vanadate and aluminate.  The pH of the raw liquor is reduced to 8.5 to 9 by the addition of sulphuric acid thereby precipitating and removing alumina; the pH is then reduced to about 4.4 by sulphuric acid addition and a solution concentrated to about 60 DEG  Be. and cooled to about 24 DEG C. whereupon the bulk of the sodium sulphate crystallizes out.  The red liquor so obtained is treated as shown in Fig. 2 by the addition of an alkaline earth metal dichromate freshly prepared from chromic acid and the alkaline earth metal oxide.  Such addition may be effected to the red liquor before or after concentration to about 70 DEG  Be. The solution is thereafter cooled and the alkaline earth metal sulphate crystallized out after standing to allow the crystals of at least 5 micron size to grow.  The finished alkali metal bichromate is then recovered and the mother liquor re-cycled. Specifications 661,945 and 661,946 are referred to.
