Abstract: A process is provided for the recovery and reuse of a salt solution obtained from a salty effluent (as herein defined) comprising: (1) passing said salty effluent, optionally after removing any fine particles therefrom, through a membrane filtration system which separates the salt in the form of a salt solution from the food residues; (2) passing said salt solution through an evaporator to decrease the water content thereof; (3) adjusting the temperature of the salt solution, typically within the range 15.degree.-25.degree. C.

Abstract: A thermosetting powder coating composition containing a solid saturated thermosetting polyester having an acid value of at least 25 and a glass transition temperature (Tg) of at least 45.degree. C. and a curing agent such as a hydroxyalkyl amide capable of reacting with carboxylic acid groups of the polyester additionally contains, as an anti-popping agent, a thermoplastic polymer which i) is solid, ii) has a Tg of 30.degree.-100.degree. C., iii) comprises, at least mainly, units derived from at least one alkyl acrylate or alkacrylate and iv) has an acid value of no more than 10.

Abstract: Finely divided micro-particles of tyrosine having a glutaraldehyde-treated allergen dispersed therein are prepared by mixing a solution of tyrosine in a strong aqueous acid with a solution of glutaraldehyde-treated ragweed pollen extract as the allergen and then neutralizing the resultant solution.
