The apparatus for vaporizing LNG comprises a heat exchanger of the intermediate fluid type and a multitubular heat exchanger, both heat exchangers using estuarine water or warm effluent water as a heat source. The process for vaporizing LNG comprises the heat exchange steps between LNG and a heating medium and between the heating medium and estuarine water or warm effluent water in an intermediate fluid type heat exchanger, and the heat exchange step between the vaporized natural gas and estuari...

A method transforming by eliminating with vacuum bulk and size of a marketplace diaper to a substantially size-reduced condition, preparatory to a traveled-to site of use, wherein the reduced size adds to convenience value during the travel.

A sealing arrangement on piston rods with a rod guided in a cylindrical compressed-gas space, particularly on piston rods of high-pressure pneumatic springs or gas-filled shock absorbers, with at least one seal disposed on the piston rod for sealing the compressed-gas space toward the outside, with a guide for the piston rod and with a lubricant space. The lubricant space is provided with an insert that is capable of absorbing the lubricant in sponge-like fashion.

A packaged ocular irrigating solution bag, which comprises a gas-permeable plastic multiple compartment bag and a gas-impermeable plastic packaging member for packaging the bag and in which an oxiglutatione-containing solution or solid preparation is enclosed in one compartment and a bicarbonate ion solution is enclosed in another compartment and the space between the bag and the packaging member has a carbon dioxide gas atmosphere.

Apparatus for packaging articles in a controlled atmosphere, such as one created by a vacuum followed by the addition of gas, such as carbon dioxide, provided within a flexible container having an open end. The packaging apparatus includes a frame and a support one the frame for the flexible container, which is preferably supported within a rigid outer container, to maintain a substantially fixed position for the articles in the flexible container. A fixed elongated member or manifold is mounted...

A package for a drug-device combination product includes an outer package including a first gas impermeable sheet and a second gas impermeable sheet hermetically sealed there to on three sides. A gas permeable header is attached to an unsealed side of the first sheet and sealed to the second sheet on two sides. The first and second gas impermeable sheets and the header form an interior and an opening communicating with the interior. A gas permeable inner package is disposed within the outer pack...

A high volume cryogen vaporizer includes a radiator where a working fluid draws heat from ambient air for vaporizing a cryogen in a heat exchanger. An electrical heater is provided for periodically heating the working fluid to defrost the radiator, thereby allowing sustained operation of the vaporizer. When not required for defrosting the radiator, the heater may be operated to heat a working fluid in a circuit separate from that of the radiator, and in which the heated working fluid is used for...

Device for the packing under vacuum of products contained in flexible bags in plastic material, creates around the opening of the bag, an airtight chamber connected to a removable air suction devices. Welding devices are suitable to weld the bag walls along a line beyond the chamber, in order to seal the bag after creating the vacuum inside it through the suction device.

A method of preserving foodstuffs in a heat-sealable plastic bag wherein three of the bag's four peripheral edges are permanently sealed together and the fourth of the edges comprises a temporary interlocking linear seal. After foodstuffs are placed into the interior of the bag, the linear seal is interlocked to form an inner chamber and to isolate those foodstuffs therein from the outside environment. The bag is then pierced to provide an opening through which the inner chamber of the bag is ev...

An apparatus for extracting air from within flexible packages having granular or otherwise flowable contents includes a package conveyor and a downwardly-open, vacuum extraction hood through which the packages are conveyed so that an upper portion of each package is moved through the extraction hood. The interior of the hood is joined in fluid communication with a vacuum source, so that air is extracted from within each package as it is conveyed through the hood. The present apparatus further in...
