Title: Comp for inhibiting metal corrosion by solutions contain - ing sodium calcium and/or magnesium chlorides
IPC: C23F11/12
Filed: 1969-05-27
Abstract: Comp for inhibiting metal corrosion by solutions containing sodium calcium and/or magnesium chlorides. F6A. comprises mixtures or aqueous solutions of salts containing 12-15% by weight of ammonium, alkaline metal or alkaline earth formates added as inhibitor. Preferably, formates are added to mixtures of calcium or sodium chlorides, containing also 0.25-1.0% by wt. of calcium or sodium hydroxide. Chlorides of sodium, calcium and magnesium are used on icy roads or as freezing salts or as dust suppressors, for example in coalmines. These are rendered much less corrosive at all concentrations. Use of formates in mixtures containing CaCl2 enables relatively large amounts of Ca or Na hydroxides to be added; this avoids the mixtures becoming more acid and corrosive by absorption of atmospheric CO2.

Title: Air-cooled condenser with air outlet heater to prevent - emission of condensate cloud
IPC: F28D5/02
Filed: 1971-05-05
Abstract: In an air-cooled, evaporative heat-exchanger, in particular a refrigerant fluid condenser, in which a fluid to be cooled passes through tubes in a vertical chimney in which a rising current of air evaporates droplets of water on the outer surfaces of the tubes. A battery of heating tubes is set in the top of the chimney to warm the air current leaving the chimney and so prevent the emission of saturated vapour which might produce an objectionable cloud of condensate on entering the atmosphere. The battery of heating tubes can be heated by precooling the fluid before it passes to the main condenser bank.
