Abstract: A liquefied carbonated gas abyssal casting apparatus prevents freezing at an outlet of a casting tube and flotation of cast carbonated gas. The liquefied carbonated gas is fed from a reservoir to a single casting tube and discharged to the abyss through an inner tube of a double casting tube from a lower end of the single casting tube. A heat medium fluid is recirculated between the inner tube and an outer tube of the double casting tube. The liquefied carbonated gas which flows through the inner tube is heated to an abyssal temperature of from -1.degree. to 5.degree. C.

Abstract: A fuel tank is provided for the automotive transport of a cryogenic liquid fuel which in the course of transport is being consumed by an engine or the like. The fuel tank consists essentially of two containers, one for the cryogenic fuel and the other for a secondary cryogenic liquid which is used to cool the fuel during storage when no fuel is being consumed. By the method of the invention the build up of fuel vapor pressure during storage is avoided and the vapor pressure maintained at a predetermined level. The fuel tank described herein was two distinct modes of operation, namely, the fuel storage mode and the fuel supply mode. In the fuel storage mode the cryogenic fuel is being stored for later use while the secondary fluid is being used as a heat sink for the heat absorbed by the tank from the environment.

Abstract: An apparatus for processing seafood, suitable for use in small ships, is disclosed. The apparatus includes a closed container having an opening and a fluid tight closure to cover the opening. Cooking water and cold brine are stored in separate reservoirs and are maintained at predetermined cooking and freezing temperatures. Seafood is placed into the closed container for processing. Cooking water is continuously circulating through the closed container from the cooking water reservoir to cook the seafood during a cooking cycle. Thereafter, cold brine is continuously circulated through the fluid tight container from the cold brine reservoir to freeze the seafood during a freezing cycle. A rinse cycle can also be employed wherein rinsing water is circulated through the container between the cooking and freezing cycles. Additionally, if just freezing of seafood is desired, the cooking steps of the method and the cooking apparatus may be eliminated.
