Title: Controlled atmos. space for freezing and packing minced meat prods.
Inventor: FRADIN MAURICE
IPC: A22C/
Filed: 1984-01-25
Granted: 1987-06-18
Abstract: The meat is minced, moulded and closed with a sealed-on cover. This is carried out in the enclosed, leak-proof space of a single or several inter-communicating rooms. A refrigerant is introduced into the space. Different regions of the space have a controlled atmos. of compsn. and temp. preselected to suit operations carried out in the regions. In partic. the pre-packing takes place directly in contact with the refrigerant but no refrigerant is injected into the tray after the prod. has been inserted. Pref. CO2 is employed as refrigerant and a supplementary gas is injected into the space to provide a protective atmos. for the prod. Pref. the space is partitioned into a main room contg. the mincer(s) and the prod. moulder, and a secondary room in which prods. are pre-packed and sealed in trays etc. Controlled atmos. conditions are maintained throughout freezing and prepackaging operations so that there is no danger of contamination of the prod. The packaged prod. requires no further injection of refrigerant which reduces processing costs.

Patent IT-1237772-B (IT)
Inventor: BRUZZESE TIBERIO
IPC: A61P31/04
Filed: 1989-11-16
Granted: 1993-06-17
Abstract: There has been prepared a series of secondary and tertiary amide derivatives of the polyene antibiotic partricin as well as of its single components, partricin A and B, having radicals on the amide nitrogen, said radicals being preferably substituted, in turn, with various amine groups. The synthesis has been carried out by reacting the C-18 carboxyl of the polyene with suitable amines, in the presence of diphenyl phosphorazidate as activator. From said amines, especially those substituted with basic groups, many salts with a good water solubility have been prepared by reacting them with pharmacologically compatible acids. It has been shown that many amines and related salts are more active than, or as active as, the starting product as antimycotic and antiprotozoan agents, while being less toxic and less hemolytic, and can therefore find a useful application in the clinical and veterinary therapy. The compounds can also be used in the treatment of hypercholesteremia and hyperlipemia conditions and of some steroid hormones unbalances, as well as in the pharmacological therapy of hypertrophic prostate, and in the treatment of lipid envelope virus infections.

Title: Stirring appts. for waste water purificn. - by injection of gas in biological treatment tank
IPC: C02F/
Filed: 1976-07-22
Granted: 1985-03-21
Abstract: Stirring appts. is intended for the treatment of waste water and sewage by the introduction of a gas; a gyratory movement is set up in a mass of liq. contd. in a recipient so as to create a vortex by the simultaneous use of a rotary device and of the earth's rotational movement. Appts. consists of a central cylindrical body extended by a cone-shaped element which is itself capped by the element; this is ovoid in shape and has an inlet from the biological tank of the appts. The circular unit serves for the admission of the atmospheric air. The body is extended downwards by the conical part which abuts on a ring; this is parallel to the plate. A paddle-wheel is mounted in the lower part of the body and is driven by the shaft; this rests in the bearing, placed below the plate, while the driving motor is fitted above the level of the water. When the appts. is immersed in a treatment tank with a biological bed, the level in the appts. is identical with the level because water can enter between the plates and by the inlet of the element. When the paddle-wheel is rotated the vortex is produced and the water drawn in tends to stick to the walls of element and absorb a large part of the oxygen in the air coming from the inlet; the water travels down the walls to join the vortex. The supersaturation of the water with air creates a large degree of expansion at a certain level in the tank; this results in intense, ascending eddy currents which bring the sludge into suspension and lead to a good oxygen circulation throughout the mass; the biological elements can, therefore, operate under excellent conditions.

Abstract: in an arrangement for mixing a first gas into a main flow a second gas, comprising a main conduit 50 for said main flow and a plurality of supply conduits 51,52,53 for the first gas which open into said main conduit, the supply conduits are araranged as at least one set of three outlet openings. This set consiste of a first opening 51 which opens into the main flow perpendicularly to the main conduit wall and two second openings 52,53 which are arranged so as each to provide a lesser flow rate of the first gas than the first opening and are offset with respect to the first opening. The three openings of the set thus direct the first gas into two contra-rotating circulatory movements W1,W2, as viewed in the direction of the axis of the main conduit. This mixing arrangement is applicable for example to mixing a hot gas into the gas obtained from an ore pellet drying bed and to mixing a hot gas into a water-laden gas from a desulphurization plant.
