Abstract: A method for guaranteeing at least one characteristic of a fluid used for producing food products. This method utilizes a system for piping and delivering the fluid, combined with means for producing the products, in order to use the fluid for producing the products; the measuring a value of the characteristic; the comparing the measured value with a predetermined threshold value; the act of executing an action if the measured value departs from the threshold value; the combining the measured value with first information for identifying at least one product; and then the storing the associated value and the associated information.

Abstract: An apparatus and method for producing products using a fluid, which enables one to control the quality of the fluid from the point of production to the point of use, monitored on a microbiological, physical, and chemical basis. At least one sensor for the acquisition of purity information and a system for storing such purity information is included.

Abstract: The invention concerns a method comprising steps which consist in: providing a system (8) for transporting and dispensing the fluid associated with means (5) for producing the products (3) to use the fluid for producing the products; measuring a value of the characteristic; comparing the measured value to a predetermined threshold; carrying out an action if the measured value exceeds the threshold value; associating the measured value with a first information identifying at least a product (3); and storing the associated value and information.

Abstract: Method of improving the breeding conditions for pigs, according to which the piglets are placed after birth in a closed or semiclosed chamber, a gaseous mixture containing oxygen is injected into the chamber, characterized in that the oxygen content of the gaseous mixture is between 25 and 50%.

Abstract: The refrigerator, in its internal cavity (2), comprises a compartment (4) in which at least a part manually movable and defining a second internal cavity (5) which is substantially water tight with respect to the first internal cavity (2) and communicating with a gas source containing less oxygen than air, typically consisting of a separation module (17) cyclically supplied with compressed air by means of a moto-compressor unit (19).Application to the long term domestic preservation of fruits and vegetables.

Abstract: Process for continuous production of vinegar by microbiological conversion with oxygen enrichment of ethanol into acetic acid. In a first phase, the micro-biological conversion of ethanol into acetic acid is performed in the presence of air. After consumption of the oxygen in the air, in a second phase, the addition of oxygen, controlled by the demand of the system, is provided by injection of pure oxygen, the aeration gas being recycled, and the gas mixture expelled as soon as the carbon dioxide content reaches the threshold of 7%. After closing of the recycling circuit, the superoxygenated atmosphere is reconstituted with pure oxygen.

Abstract: A bacterial vaccine against Salmonella fevers, typhoid and paratyphoid fevers is obtained by fermentation, extraction and purification, vaccinating membrane antigens being extracted by putting the bacterial residue, obtained by centrifuging, in contact with a solvent of the tris (hydroxyalkyl) aminoalkane class, with stirring, at lowered temperature, pH adjusted between 8.4 and 8.6 for a period of at least some 60 hours, then, separated by decanting, followed by purifying the antigens and fractionating by ultrafiltration, and then freeze-drying the vaccinating antigen fraction. Such vaccinating antigen fraction has a molecular weight greater than 50,000, preferably 300,000, and is used to vaccinate humans and animals.
