Title: Wine-making plant including heating portion of grapes - before fermentation to improve maceration and extn. of colouring matter
IPC: C12G1/028
Filed: 1975-06-17
Abstract: The grapes are removed from their stalks and crushed. Depending upon the quality of the vintage, a portion of the juice is sent directly to the wine-making tower. The portion to be heated goes to the drainer which is fitted with an inclined endless screw where the mass remains for the time necessary for half the juice to drain out and be transferred to the tower. The drained mass passes to a heater, also fitted with an inclined endless screw, where it is heated to 50-80 degrees C. by a boiler and heat exchanger. On leaving the heat it passes into a vertical cooler which is provided with a closed cold water circuit. After cooling to 30 degrees the treated mass is introduced into the tower. During bad ripening years the process gives a better extn. of the polyphenols without accentuating the roughness of the wine as well as the optimum extn. of the colouring matter. During normal years of maceration is accelerated and a better yield obtd. A portion of the polyphenoloxydase enzymes is destroyed.

Title: Mattress or dinghy inflation system - uses double wall with separate inflation valve to draw in air upon deflection of support frame
IPC: B63B7/08
Filed: 1976-03-18
Abstract: The time required to inflate equipment e.g. inflatable mattresses dingies or tents can be considerably reduced by providing the equipment with a double wall with a separate inflation valve. The space between these walls is inflated through a valve is so that the equipment assumes it operational shape and at the same time draws in air from the atmosphere through a second valve. If required additional air may then be pumped through a second valve to maintain the internal pressure above that of atmosphere. Instead of a double wall of a framework of inflatable tubes may be used so that any desired final shape can be achieved.
