Abstract: 658,869. Automatic regulators. COHEN, A. M. Feb. 16, 1949, No. 4253. Convention date, June 22, 1948. [Class 38 (iv)] A voltage or like circuit regulator comprises a row of fixed contacts 16 normally engaged by an equal number of contact spring fingers 20 which are sequentially lifted out of engagement by a finger lifting member 66 biassed by springs 80 and movable downwards substantially in its own plane by an armature 56 mounted on a flexible sheet 58 so as to pivot about a central point when attracted by an electromagnet 34. As seen in Fig. 2 the sequential actuation of the contact fingers 20 is effected by making the lower edge of the member 66 oblique. The strength of the springs 80 is adjustable by bending the fingers 86 that support their upper ends and a dash-pot 90 provides a slow action. The armature 56 is riveted at 62 and 128, Fig. 7, to the sheet 58, the end 70 of which contains an elongated aperture 76 which passes over a tongue 74 on the member 66, so providing a pivotal connection between the members 58 and 66.

The particles may be retained on the body or the die by means of a thin coat of petroleum jelly, if the pressing is done cold, or on the die by soft soap &c. if the body, e.g. of steel, is heated before pressing. A succession of layers of grinding particles may be forced into a body by repeating the process as desired and. if the particles do not project sufficiently, some of the body metal may be removed by acid or other chemical. Grinding particles may be forced into faces parallel with the direction of applied pressure by causing this to expand the body as shown in Fig. 2.

Title: Process for separating compounds of potassium from compounds of aluminium
IPC: C01D9/04
Filed: 1925-02-17
Abstract: Aluminium and potash present together in minerals are converted into nitrates and the resulting mixed nitrates are separated by washing with nitric acid which removes all the potash but little aluminium. In an example, leucite is treated with a residual liquor containing nitric acid, potassium nitrate and aluminium nitrate obtained at a subsequent stage in the process.  After the insoluble silicic acid has been filtered off and the solution slightly evaporated, pure potassium nitrate separates on cooling. The mother-liquor is further concentrated to obtain a mixture of potassium and aluminium nitrates on crystallizing.  By washing with 60 per cent nitric acid, pure aluminium nitrate remains while the wash liquor containing aluminium and potassium nitrates is used for treating further quantities of leucite after the addition of nitric acid.  When stronger nitric acid is employed for treating the crystalline mixture of nitrates, less aluminium is obtained in solution, so there is less aluminium in the circulating liquor.ALSO:Aluminium and potash present together in minerals are converted into nitrates and the resulting mixed nitrates are separated by washing with nitric acid which removes all the potash but little aluminium.
