Abstract: A METHOD OF WASHING SOLID, MORE PARTICULARLY TEXTILE ARTICLES WITH AN ORGANIC SOLVENT, IMPROVED BY ADDING AN INTENSIFIER. THE INTENSIFIER IS A PRIMARY OR SECONDARY AMIDE OF A DICARBOXYLIC ALIPHATIC ACID OR ANHYDRIDE WHEREIN ONE CARBON ATOM IN THE CHAIN CONNECTING THE TWO ACID GROUPS BEARS AN ALKYL OR ALKENYL RADICAL CONTAINING AT LEAST SIX CARBON ATOMS. THE METHOD GIVES BETTER WHITENESS AND MORE PARTICULARLY PREVENTS THE RE-DEPOSITION OF DIRT.

Abstract: GANISMS SIGNIFICANTLY IMPROVES THE EFFICIENCY OF GAS UTILIZATION IN BIOLOGICAL AERATING SYSTEMS.

A PROCESS FOR INTRODUCING A GAS INTO A SUSPENSION OF MICROORGANISMS WHEREIN A DENSE BED OF INTRODUCED GAS AND LIQUID MICROORGANISM SUSPENSION IS CREATED IN THE UPPER ZONE OF A TREATMENT RECEPTACLE BY COUNTER-CURRENTLY INTRODUCING A UNIFORM DISPERSION OF A GAS AT A CONSTANT RATE INTO THE BASE OF A TREATMENT RECEPTACLE HAVING DISPERSED THEREIN A LIQUID SUSPENSION CONTAINING MICROORGANISMS, WHICH SUSPENSION IS INTRODUCED AT THE TOP OF SAID RECEPTACLE AND THE UPPER ZONE DENSE BED IS SEPARATED FROM A LESS DENSE LOWET ZONE BY AN INTERMEDIATE INTERFACE ZONE. THE UPPERMOST LAYER CONTAINS A GREATER QUANTITY OF GAS THAN THE LOWER LAYER AND BY CONTINUOUSLY REGULATING THE RATE OF SUSPENSION WITHDRAWAL FROM THE RECEPTACLE THEREIN IS MAINTAINED A STABLE DENSELY PACKED BED OF GAS AND MICROORGAISM SUSPENSION.
