Abstract: A process for the treatment of an acid hydrolysate of vegetable matter for separating it into a dark colored fraction and a light colored fraction is disclosed. In a turbulent flow, it is placed in contact with at least one semi-permeable membrane which is stable in an acidic medium under a pressure of from 4 to 50 kg/cm.sup.2 which produces a first lightly colored liquid or permeate which passes through the membrane, the average color intensity of which, measured by its extinction, is about one tenth of that of the hydrolysate, and a second strongly colored liquid or retentate which does not pass through the membrane. The dried retentate is used as a seasoning and/or coloring agent.

Abstract: A continuous method of impregnating food material such as vegetables, fruit, meat, eggs, and fish wherein pieces of the food material are immersed in a concentrated solution, such as brine, syrup, meat curing solutions, humectant solutions and mixtures thereof, said pieces being initially buoyant in said solution and being passed together with said solution along a flow path to a separation zone wherein the impregnating solution flows downwards at a rate greater than the rate of flow of the food material whereby those pieces of food material which, by absorption of the desired quantity of impregnant, have lost sufficient of their buoyancy in the surrounding impregnating solution to be carried downwards by the said solution, are continuously separated from pieces of food material which have absorbed less than the desired quantity of impregnant.

Abstract: A process for the extraction of uranium from ores which is an improvement in the known "dry attack" treatment of uranium ores to an economical yet high rate of extraction. The process concerns solubilization of the uranium contained in the ores and consists of carrying out digestion of the mixtures of ore and reagent, with the possible addition of oxidizing agents. The process is carried out on an improved trough type of conveyor belt at predetermined conditioning of temperatures and humidity.

Abstract: A method for heating crude oil to be processed in a petrochemical installation, comprises successive heat exchangers disposed in series, each heat exchanger using pressurized steam as the heating fluid. Each exchanger has a lower exchange chamber, a liquid product supply line and a tube bundle, the steam transferring heat to liquid product flowing through the tube bundle. Each heat exchanger comprises an upper separation chamber disposed above the lower exchange chamber, the separation chamber having a gas phase outlet and a liquid phase outlet, the liquid phase outlet being disposed lower than the level at which the tube bundle extends into the separation chamber. Successive heat exchangers are connected together by a pipe communicating between the liquid phase outlet of the upper separation chamber of one of the heat exchangers and the liquid product supply line of the next heat exchanger.
