Title: Apparatus for weighing and for delivering predetermined quantities  of tea and like articles continuously and automatically
IPC: G01G13/22
Filed: 1972-05-22
Abstract: 1322679 Automatic weighing and dispensing WILLIAMSON MAGOR AND CO Ltd 22 May 1972 [22 May 19711 23945/72 Heading G1W Apparatus for automatically dispensing predetermined weights of material comprises a container 1 rotatably mounted on a spring balance 8. Material continually falls from a hopper into an uppermost compartment 2 which is held in position by a plunger 12 until its weight causes a pointer 17 to close a micro-switch 16 placed in a predetermined position. This completes an electric circuit causing the plunger 12 to be withdrawn thereby allowing the compartment 2 to rotate under gravity so as to dispense the material. As the weight on the balance decreases, the switch 16 opens so as to hold the compartment now uppermost in position. A revolution counter 18 allows the total weight of material dispensed to be calculated.
Patent GB-808637-A (GB)
Title: Improvements in or relating to the recovery of selenium
IPC: C01B19/00
Filed: 1956-08-03
Abstract: Selenium is separated from selenium-containing materials, e.g copper refinery anode slimes, by treatment with an alkali metal hydroxide in either molten or dissolved form to obtain a soluble alkali metal selenate; precipitating the selenate in the form of a water-insoluble selenate, preferably the barium, strontium or radium selenate, and especially barium selenate, reducing the insoluble selenate to a soluble selenite, and reducing the selenite in solution to form selenium.  When the initial stage is carried out by fusing the material with an alkali metal hydroxide, it is convenient to add an oxidation promoter, preferably selected from the following: hydrazine, cobaltimine ion, lead dioxide, chlorate ion, perchlorate ion, tellurate ion, peroxides, nickel dioxide, hypoiodite ion, manganate, bromate, chlorite, hypobromite, hypochlorite, ferrate, or an acid periodate (H3CO6­) ions, hydroxylamine, chlorine dioxide or ozone.  In an example, unroasted copper refinery anode slimes are treated with an alkali-metal hydroxide, either in molten condition or in solution at elevated temperatures and pressures. In the first case, the product is leached, and then in both cases the solution is filtered.  To this solution is added a soluble barium compound, preferably the chloride or oxide, thereby precipitating barium selenate, which is collected and washed. The precipitate is now reduced by the action of an acid containing an oxidizable ion, preferably hydrochloric acid, either alone or mixed with sulphuric acid.  Hydrobromic and hydroiodic acids may also be employed.  When hydrochloric acid alone is used, chlorine is liberated and a solution of barium selenite is obtained.  When sulphuric acid is present, barium sulphate is precipitated and a solution of selenious acid is obtained.  An alternative procedure is to treat the precipitate of barium selenate with sulphuric acid alone to obtain a solution of selenic acid, and then reduce this to selenious acid with hydrochloric acid.  The solution containing the selenite ion is now reduced, preferably by sulphur dioxide, or by zinc powder or hydrogen, to give a precipitate of substantially pure selenium.

Title: Surface treatment of aluminium base alloys and resulting product
IPC: C25D11/16
Filed: 1962-06-25
Abstract: High strength anodically oxidized wrought aluminium base alloy products are made by using an acid electrolyte to anodize a hardenable hot worked alloy containing 0.75-2% by weight of magnesium silicide, 0.2-0.4% chromium and balance except for impurities, aluminium.  Both magnesium or silicon may be in excess of the proportions required to form the silicide. Small amounts of grain refining elements may be present, e.g. B, Ti, Zr, and Mo, in total 0.3%.  The alloy is first heat treated at 1075-1130 DEG  F. for sufficient time to bring the Cr, Si, and Mg into solution, after which it is cooled and hot-worked at 700-1000 DEG F. to form extrusions, forgings, or pressings.  This is followed by rapid cooling or quenching, the Mg and Si remaining in solution, and anodized electrolytically using as electrolyte, H2SO4, oxalic, sulphosalicyclic, phosphoric, or chromic acid, producing a range of colours.  The anodized surface is then sealed using an aqueous solution of a nickel salt.  A precipitation-hardening stage at 375-390 DEG F. or 460-475  DEG F. may be applied before or after the hot working stage and before anodizing.
