Title: Improvements in process for obtaining mgo and caco from dolomitic materials
IPC: C01F5/06
Filed: 1936-12-11
Abstract: In the treatment of an oxide calcine containing a mixture of CaO and MgO with a readily soluble magnesium salt solution such as the chloride, nitrate, or acetate to obtain a calcium salt solution and magnesium oxide, slightly, say 1 per cent, less magnesium salt solution is used than is theoretically necessary so that the final calcium product (CaCO3) may be free of magnesium and fluorine.  A fraction, say \ba1/8\be, of the magnesium salt solution is first added to convert the CaO present to Ca(OH)2 and the remainder then added to effect the main reaction which is promoted by agitation. After separation of solids the calcium salt solution is treated with NH3 and CO2 or ammonium carbonate using slight excess of NH3 to precipitate calcium carbonate and obtain an ammonium salt solution which is then reacted with the said solids at an elevated temperature to recover ammonia and magnesium salt solution for reuse, and give as solid end product the MgO derived from the calcine.  A flow sheet for the process is given.

Abstract: 1367814 Dispensing viscous liquids DAGMA GmbH & CO DEUTSCHE AUTOMATEN-UND GETRANKE-MASCHINEN 24 July 1972 [24 July 1971 5 Feb 1972] 34549/72 Heading T In a method and apparatus for dispensing viscous liquid, e.g. sugar-rich syrup, in a drink vending machine, a container 1 is filled with the liquid, after removing a cam inlet sealing stopper 6, at atmospheric pressure. On lifting housing lid 19, valve 12 in a vent tube 11 entering the liquid is closed so that liquid only rises a small amount into the bottom 13 of tube 11. On closing inlet 23 and the lid, valve 12 is opened to release the increased pressure in tube 11 so that a negative pressure is produced above the liquid in container 1. On energizing solenoid 10 above the container armature 9, connected to ball or cone valve 7 by rod 8 passing along the tube 11, opens valve 7 to discharge liquid at 3, the liquid in tube 11 falling to the bottom of the tube so that bubbles of air rise to the surface of the liquid in container 1. By suitable dimensioning or tilting of tube 11, air bubbles of such a size are produced that during the time taken to rise to the surface they become saturated with moisture. The construction of valve 7, 8, 9, the positioning of solenoid 10 to stop heating of the liquid, the negative pressure above the container liquid and the dimensioning or positioning of the ventilating tube 11 to produce bubbles which will not reduce the humidity above the container liquid, are stated to reduce the drying out and formation of deposits in the apparatus. Lid 19 may be dispensed with and valve 12 replaced by a normally closed flap valve which opens under reduced pressure in tube 11.  Ball valve 7 may be rotatably connected to rod 8, and rod 7 pass through a guide at the bottom of tube 11 keeping valve 7 away from the container walls when open.

Abstract: Condensation products probably corresponding to N-methylolated hydroxyalkyl carbamates are prepared by reacting a hydroxyalkyl carbamate with formaldehyde in an aqueous alkaline solution having a pH of at least 8.5, the mole ratio of formaldehyde to said hydroxyalkyl carbamate being at least 1.5: 1.  Examples describe the reaction with formaldehyde of 2-hydroxyethyl, 2-hydroxypropyl and 2,3-dihydroxypropyl carbamates.ALSO:Wrinkle-resistance and wash-wear properties are imparted to cellulosic fibrous materials such as cotton print cloth or viscose rayon fabric by immersing them in a bath containing (1) a condensation product prepared by reacting at least 1.5 mole of formaldehyde with each mole of a hydroxyalkyl carbamate in an aqueous solution having a pH of at least 8.5 and (2) an acidic salt catalyst, maintaining a period of dwell to enable the said composition to penetrate into and through the cellulosic material, removing excess composition (e.g. by padding or centrifuging) drying the wet cellulosic material and curing the dried material at elevated temperatures.  Prior to curing, the treated material may be softened by passage through a button-breaker, passed through a friction or embossing calender to impart permanent physical finish effects or converted into garments.  Specified acidic salt catalysts are zinc nitrate hexahydrate and magnesium chloride hexahydrate.  The treatment bath may also contain softening, wetting or fluorescent agents.  The finished fabrics are preferably washed in a non-ionic detergent solution.
