Patent GB-828675-A (GB)
Title: Process for making mixed fertilizers containing ammonium nitrate and calcium carbonate
IPC: C05C1/00
Filed: 1958-01-08
Abstract: A process for producing a mixed fertilizer containing ammonium nitrate and calcium carbonate comprises mixing calcium carbonate with molten ammonium nitrate in the presence of at least 1% of ammonium monohydrogen phosphate or potassium monohydrogen phosphate, solidifying the mixture and granulating.  The process reduces the loss of nitrogen from the fertilizer following the admixture of ammonium nitrate with the calcium carbonate. Preferably the granulation is carried out by flowing the molten mixture on to a moving, flat endless belt on which it solidifies and is then granulated to the required particle size.  The monohydrogen phosphates are added per se to the mixture of ammonium nitrate either beofre, with or after the calcium carbonate, but the ammonium monohydrogen phosphate may also be formed in situ in the molten ammonium nitrate by adding phosphoric acid to the nitric acid in the production of the ammonium nitrate or by adding phosphate rock to the nitric acid in the same process.  Any form of calcium carbonate, including limestones with at least 95% calcium carbonate content, may be used in the process of the invention; the dolomitic limestones do not cause the high nitrogen loss experienced on adding pure or commercial calcium carbonate to ammonium nitrate.  The calcium carbonate is added to molten ammonium nitrate at temperatures such that the mixture remains fluid enough to be run on to the flat belt for solidification, e.g. temperatures above 350 DEG C.  Specification 791,647 is referred to.

Title: Flotation of fluoride ores
Inventor: PERRI GIOVANNI
IPC: B03D1/001

Abstract: 1,220,556. Froth flotation. MONTECATINI EDISON S.p.A. 8 Jan., 1970 [9 Jan., 1969], No. 917/70. Heading B2H. In a process for the flotation of calcium fluoride a flotation slurry containing calcium fluoride is conditioned with a polyethylenoxy alkylpahenol as a depressant and a polyethylenoxy ester of a fatty acid as an activator. The muddy deslimed or slimy raw mineral is pulped in water to form a slurry which is then conditioned with the alkylphenol and the fatty acid ester. The following flotation reactants can be added to the conditioned slurry: an unsaturated fatty acid, e.g. oleicacid, as a collector for the fluoride; a starch, e.g. dextrin, as a depressant for silica; sodium fluoride as an activator (this may be totally or partially substituted by the fatty acid ester); and a tannin, e.g. as in quebracho extract, as a depressant for calcite. Air is then blown in and the mass is floated in a number of steps. Examples are given.

IPC: B66B13/30
Filed: 1994-01-06
Abstract: PURPOSE:To obtain a reconstructing method for an elevator door device which can shorten the continuous term of impossible operation occurring in an existing elevator when a door device is exchanged and repaired. CONSTITUTION:An existing riding stop door device is exchanged for a new riding stop door device, and the existing engaging body of the existing cage door device 1 is withdrawn, and a new engaging device 91 actuated by the existing cage door device 1 is attached. The new engaging body 81 of the new engaging device 91 is engaged with the new engaging piece of the new riding stop door device to actuate an elevator door device for usual operation. Thus the reconstructing work of both the cage door device and the riding stop door device can be executed without the restriction of order and at severally different times. Each condition of the existing elevator can therefore be made to flexibly correspond for lessening the occurrence of the state of impossible operation continuing for a long period of time to the utmost.

Abstract: PURPOSE:To prevent an interlayer short-circuit due to a hillock by treating a semiconductor substrate in an oxidative atmosphere before a through hole is opened to insulate the hillock part of a first wiring layer penetrated through an interlayer insulating film. CONSTITUTION:After an aluminum wiring pattern 2 of first layer wirings is formed on a semiconductor substrate 1, an interlayer insulating film 3 is formed on the whole substrate 1 by flattening the surface. When the substrate 1 is treated in an oxidative atmosphere, aluminum of a hillock 4 part penetrated through the film 3 is changed to aluminum oxide, and the hillock 4 becomes an insulated hillock 5. Then, through holes 6 are opened at necessary positions of the film 3, a second layer wiring pattern 7 connected to the pattern 2 is formed by the holes 6 on the film 3 as a multilayer interconnection structure. Thus, an interlayer short-circuit due to the hillock can be prevented.
