Title: Improvements in the electrolytic recovery of zinc from zinc bearing ores and metallurgical products
IPC: C25C1/16
Filed: 1923-07-31
Abstract: In the recovery of zinc from ores or metallurgical products, the residue after leaching the roasted material with spent electrolyte, is mixed with strong sulphuric acid in a rotating drum or other apparatus, and is preferably formed into nodules. It is then dried and heated in a shaft or other furnace to which gases containing sulphur dioxide, such as roaster gases, are supplied.  The furnace temperature is sufficient to decompose iron sulphate but not zinc sulphate.  The product is then leached with part of the solution obtained in the previous leaching, and the resulting solution is added to the main circuit.  The gases leaving the furnace are conducted to a plant for the recovery and production of sulphuric acid.  The product of the first leaching is classified into slimes and coarse material, the former of which is thickened and decanted and the residue filtered for the acid treatment.  The coarse material is treated by flotation, and the tailings filtered and added to the slime residue, the concentrates being roasted for production of the gases used in the furnace treatment and the calcines returned to the initial leaching-vats.  The liquid products of both leachings are agitated with limestone to precipitate iron and silica and are filtered before return to the cells.  Chlorides may be added to precipitate silver, if sufficient chloride is not present in the leaching-solution.

Title: Improvements in or relating to television signal generation
Inventor: MCGEE JAMES DWYER
IPC: H01J29/45
Filed: 1962-05-24
Abstract: 1,025,271. Television; cathode-ray tube circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 19, 1963 [May 24, 1962], No. 20048/62. Headings H4F and H4T. [Also in Division H1] A method of generating television signals involves the use of a picture-signal generating tube having a target comprising a layer of photo-conductive material separated from a conducting signal plate by a transparent dielectric layer. An optical image is formed on the photo-conductive layer and the target is scanned by an electron beam deflected to form interlaced alternate frames. By changing the tube gun cathode potential between zero and minus 100 volts the alternate frames are arranged to be of low and high electron beam energy whereby the parts of the target impinged during said frames are brought respectively towards cathode potential and (by virtue of secondary emission) towards a positive potential of some 5 - 10 volts. The resulting picture signal currents in a resistor connected to signal plate are respectively negative going and positive going, and are brought to a common polarity by reversing the video signal in every other frame. The photoconductive layer may be formed as a continuous layer or as an array of parallel, separated strips extending the full height of the target at right angles to the line scan direction. The target construction permits the use of photoconductive materials of specific resistivity lower than those normally encountered in a conventional vidicon tube and particularly materials sensitive to infra-red radiation, such as lead sulphide, lead selenide and lead telluride. For infra-red operation it is necessary to screen the photo-conductive layer from infra-red radiation from the tube gun. This may be done by interposing a phosphor-photocathode screen.
