Title: Process for recovering gallium in the purification of crude alumina
IPC: C01G15/00
Filed: 1961-07-17
Abstract: Alumina, especially Bayer alumin, is purified by dissolving in hydrochloric acid, subjecting the resulting solution to anion exchange with an anion exchanger, which may be a resin or a liquid amine anion exchanger, the latter optionally diluted with an inert organic diluent, or a solvent which is a trialkyl phosphate or phosphine oxide, a dialkylalkyl phosphonate, an alkyldialkyl phosphinate, each alkyl having 3 to 6 carbon atoms, or methyl isobutyl ketone. An organic diluent, especially kerosene may be used when methyl isobutyl ketone is not the solvent, tributyl phosphate being the solvent of choice.  The alumina is preferably recovered from the aqueous phase by saturating with gaseous hydrogen chloride, and igniting the precipitated hexahydrate of aluminium trichloride. The gallium concentrate is recovered by washing the ion exchanger or solvent with a mixture of equal weights of water and concentrated hydrochloric acid, then extracting the gallium and other impurities with water to produce an aqueous solution, neutralizing the gallium containing solution with ammonia and firing the precipitate formed. The examples illustrate the use of solid anion exchangers, tributyl phosphate diluted with kerosene, and a liquid amine anion exchanger. Specification 991,613 is referred to.

Title: Improvements in web-tensioning devices
Inventor: PACKER JOHNSON LEWIS
IPC: B65H23/04
Filed: 1950-10-27
Abstract: 704,672. Unwinding webs. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Oct. 26, 1951 [Oct. 27, 1950], No. 26285/50. Class 100 (1). [Also in Groups XXV and XXXIV] A web, being unwound from a reel, is tensioned by a brake adjusted to vary the braking effect on the reel controlled by the web passing over an aperture through which compressed gas supplied to a pneumatic chamber is allowed to leak, such that the web tension controls the escape of gas, the pressure changes in the chamber being translated into appropriate adjustments of the brake by a relay. As applied to a machine for winding a web around an electric conductor passing through a spindle 7, a web 1, unwound from a reel 2 rotatably mounted on a spindle 3 by a hollow boss 16, is braked by a friction disc 23 engaging a brake disc 20, the spindle 3 being rotatable around the spindle 7. The reel 2 is tightly gripped between the disc 20 and a removable screwed disc 21. The friction disc 23 is secured to a ring 24 carried by a resilient spider 25 mounted on a boss 130, such that appropriate deflection of a diaphragm 28 of a pressure chamber 27 causes flexing of the spider and application of the brake. Compressed air reaches the chamber 27 through passages 34, radial apertures 32 terminating in key-ways 33, a passage 31, and a pipe 35. A valve 38, controlled by a pneumatic relay 39, determines the air pressure in the chamber 27 and thus the braking effect of the disc 23 in accordance with the web tension as detected by a slot 159 in a nozzle 54 over which the web passes. An increase in web tension thus causes an increase in air pressure in a chamber 52 due to a reduction in air leakage through the slot 59, the increased pressure causing deflection of a diaphragm 57 and movement to the right (as seen in Fig. 3) of a valve stem 58 secured thereto. The stem 58 operates a slide valve 45 within a sleeve 46 connected to pipes 48, 49 and 50, such that air pressure is supplied from the pipe 48 via the pipe 50 to a chamber 41, thus causing movement of a diaphragm 43 and valve stem 44 to open the valve 38. Similarly, a reduction in web tension causes opposite movement of the stem 58, thus supplying air pressure to a chamber 40 and resulting in closing of the valve 38 by actuation of a second diaphragm 43 connected to the stem 44.

Abstract: 861,190. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 15, 1958 [Aug. 22, 1957], No. 26496/57. Class 106 (1). In an electrical digital computer, a programme is interrupted when coincidence is detected between digits of an instruction word and preselected digits set up on switches. The serial computer described employs an instruction word having two parts which relate to the current operation and the next instruction respectively, and is arranged to stop if the digits in either part correspond with the digits set up on associated " stop " switches. The first part includes " waiting time " digits W and " transfer " digits X; the W and X digits set up on the switches are dynamicized and applied over line 4 for comparison at non-equivalent gate 2 with the W and X digits in the current instruction applied over line 6. If and only if coincidence occurs in every digit position, trigger 10 will remain " on," thus opening gate 14 to cause " stop " trigger 16 to be set by a pulse subsequently applied to line 12. The second part of the instruction includes " source " digits N and " time " digits T. If coincidence is detected for the N digits a signal appears on line 24 (from a gate similar to 14) which causes the next minor cycle pulse on line 30 to set trigger 32 and open gate 36. A T-digit coincidence signal on line 34 then similarly causes the next minor cycle pulse on line 42 to set the " stop " trigger 16. When trigger 16 is set it prevents the " ready " signal generated on line 20 during the (W - 1) minor cycle from preparing the computer through line 22 for carrying out the current instruction in the case of W and X coincidence, and the next instruction in the case of N and T coincidence. The T switches may be compared with the contents of a minor cycle counter instead of the T position of an instruction. Reference is made to a parallel computer in which the instruction used is compared with the setting of the stop switches at a plurality of gates. Specifications 717,114 and 719,066 are referred to.
