    Abstract: Liquid natural gas is pumped into a main tank until the main tank is completely filled with liquid. Once filled, high pressure gas is pumped into the main tank. This high pressure gas forces the liquid from the main tank into an overflow tank until the liquid level in the main tank reaches a predetermined level. High pressure gas is then pumped through the main tank to the overflow tank until the LNG in the overflow tank is saturated at a pressure slightly higher than the pressure needed at the use device. Once the desired pressure is achieved the delivery of LNG to the delivery system is stopped. LNG is initially delivered from the overflow tank to the use device as a high pressure gas. Some of the high pressure gas being delivered from the overflow tank is diverted from the use device to saturate the LNG in the main tank at the desired pressure. The LNG will be delivered from the overflow tank is depleted and then the LNG will be delivered from the main tank which will have been saturated by the high pressure gas from the main tank.

    Abstract: A natural gas fuel storage and supply system, particularly suited for use in vehicles powered by liquid natural gas (LNG), includes an insulated tank containing a supply of LNG with a headspace there above. A pump and a vaporizer are in circuit between the tank and the engine of the vehicle. When activated, the pump pressurizes LNG from the tank and directs it to the vaporizer where gaseous LNG is produced. The pressurized gaseous LNG is routed to the engine where it is consumed as fuel. An economizer circuit communicates with the headspace of the tank and includes a regulator, a control valve and a flow control device. The control valve opens when the vehicle engine is in operation and the regulator opens when the pressure in the tank exceeds a predetermined level so that LNG vapor from the tank headspace flows to the vehicle engine air inlet where it is consumed. The flow control device, which may be an orifice or a flow control valve, is set to prevent the LNG vapor and air mixture created at the air intake from being combustable in the vehicle engine.

    Abstract: An improved liquid cryogen dewar for storing cryobiological materials is disclosed having an inner tank with a reservoir holding a pool of liquid cryogen. A rotatable tray is contained within the inner tank, containing a platform, vertical dividers and a thermally conductive cylindrical outer sleeve, which contains a skirt extending into the pool of liquid cryogen. The sleeve transfers entering heat away from the cryobiological materials and into the liquid cryogen pool. The sleeve maintains a consistently low temperature throughout the vertically disposed shelves of the cryobiological materials contained within the inner tank.

    Abstract: The storage tank consists of a main tank and ullage tank connected by a relatively small passage having a flow rate capacity up to 30% of the main fill line. To fill the tank, liquid cryogen is delivered to the main tank by either a top or bottom fill. Because the fill line is significantly larger than the passage, the main tank will become liquid full while the ullage tank remains substantially empty. When the tank becomes liquid full a dramatic drop in the flow rate will result that can be detected by a relatively insensitive, and inexpensive, flow monitoring device thereby to stop the filling operation. The ullage tank will retain trapped gas and gradually allow the liquid from the main tank to enter the ullage tank through the passage until the liquid level in the tanks are equal. Once the liquid levels in the tanks equalize, a vapor space is created above the liquid to accommodate vaporizing cryogen and provide long hold times.

    Abstract translation: 储罐由一个主槽和一个相当小的通道连接的排水箱组成，流量可以达到主填充管线的30％。 为了填充油箱，液体冷冻剂通过顶部或底部填充物输送到主油箱。 因为填充线明显大于通道，所以主油箱将在液体充满的同时保持空白。 当罐变得液体充满时，流量的显着下降将导致可以通过相对不敏感且廉价的流量监测装置来检测，从而停止填充操作。 排空罐将保留被捕获的气体，并逐渐允许来自主罐的液体通过通道进入排空罐，直到罐中的液面相等。 一旦罐中的液面均匀化，就会在液体上方产生蒸汽空间，以适应蒸发的冷冻剂并提供较长的保持时间。

    Abstract: The present invention uses an on-board source of compressed natural gas (CNG) to pressurize the LNG in the vehicle's LNG storage tanks such that high pressure natural gas can be delivered to the use device. More than one LNG storage tank can be used without increasing the amount of CNG required if the storage tanks are connected together in series so that the upstream storage tank pressurizes the downstream storage tank.

    Abstract: A cryogenic dewar features an inner tank surrounded by an outer shell with the space there between vacuum-insulated. A pressure vessel containing a cryogenic liquid refrigerant, such as liquid nitrogen, is positioned at least partially within the interior of the dewar to cool it. The pressure vessel is pressurized so that the temperature of the cryogenic liquid may be controlled. A refrigeration device and temperature or pressure sensor communicate with the cryogenic liquid in the pressure vessel. When the sensor detects that the cryogenic liquid has warmed above a predetermined level, the refrigeration device is automatically activated to cool the cryogenic liquid.
