    Abstract: A trailer with piping and accessories capable of maintaining the ultra high purity of a cryogenic liquid while receiving and transporting the liquid, purging an external receiver, and transferring liquid to the receiver. The trailer has a heat exchnger for vaporizing a liquid flow from its liquid container into warmed gas. The gas is used for purging an external receiver and for pressurizing the liquid container sufficiently to transfer liquid into the purged receiver. The trailer piping allows purging of and then transferring to the receiver without opening any connections. The number of welded surfaces in the trailer capable of trapping and generating contaminants are reduced, particularly the number of welded penetrations of the liquid container.

    Abstract: A gas container connecting device for portable gas stove is related to a gas container connecting device, particularly to the kind which is used for portable gas stove either for outdoor or indoor activity. It utilizes a pair of claws formed on a connecting means to hold the rim portion commonly found on gas container, therefore, no additional support is required to hold the gas container, so that the gas container can be secured in open-ended position to facilitate the operation thereof.

    Abstract: System for safety storage of liquids including a closed horizontal cylindrical primary tank inside a partially closed horizontal cylindrical secondary tank spaced apart from each other so as to provide an open space around the outside of the primary tank and the inside of the secondary tank. The outer secondary tank being closed at one end with a circular head and being open at the other end with its original head repositioned interiorly so as to substantially close the secondary tank and leave an open recessed area inside the tank walls and outside the repositioned head; supporting structural beams along the outside of the secondary tank to support the outside system in a horizontal position; spacer skid members inside longitudinally along the inside bottom of the secondary tank on which to rest the primary tank; vents to vent each tank to the outside atmosphere, measure relief value, and a lockable filler housing through which the primary tank can be filled with liquid; a liquid pump connected to the inside of the primary tank to pump liquid therefrom through an exit delivery hose and nozzle; a suction pipe line connecting the primary tank to the liquid pump; and a closure plug for opening and closing the suction pump line.

    Abstract: A hand truck includes a carrying device connected to a wheel arrangement for transporting a load on a first support surface. The wheel arrangement is slidably displaceable with respect to the carrying device and can be selectively secured in a locked position when moving the hand truck on the first support surface. The carrying device including the load is transferable to a second elevated support surface when the wheel arrangement is slid toward a handle end of the carrying device. The wheel arrangement may be removed from the carrying device or alternatively pivoted for placement on the second support surface.
