    Abstract: A method and apparatus for subcooling a liquid composed of a volatile fluid, for instance, a saturated liquid cryogen, in which two chambers are filled with the fluid and are each initially pressurized after filling so that the fluid is converted to a subcooled liquid. The pressurization of the two chambers is maintained as the subcooled liquid is delivered from each of the two chambers. The filling and the delivery of the two chambers is effected in accordance with a cycle in which one chamber is filled and initially pressurized just prior to the completion of the delivery from the other chamber to allow the continual delivery of the subcooled liquid.

    Abstract: Apparatus for providing a simulated space environment for the testing of articles under low temperature conditions comprising a liquid nitrogen head tank, liquid nitrogen subcooler pumps, a liquid nitrogen subcooler coil, a liquid nitrogen head tank makeup pumps, a low pressure liquid nitrogen storage tank, a high pressure liquid nitrogen storage tank, a liquid nitrogen transfer pump, a vacuum chamber and thermal simulation heat exchanger shrouds contained within the vacuum chamber. Appropriate internal and external piping connects these components so that the apparatus can be operated both in a subcooled pressurized closed loop system as well as in a gravity convection system. While liquid nitrogen in this apparatus will produce a stable uniform temperature of -297.degree. F. within the shroud containing the article to be tested, other liquids with similar low temperature characteristics may be used. A requirement for such liquids when used as a circulating medium with the apparatus herein is that the boiling point thereof at one atmosphere will produce the required test operating temperature.

    Abstract: Containers are pressurized by adding a controlled amount of liquid cryogen to uncapped containers as they move along an assembly line to a capping station. The liquid cryogen is added to the containers in a stream from a conduit outlet. The amount of cryogen delivered is controlled by sub-cooling the liquid cryogen as it flows across a flow-control restriction in the conduit, thereby ensuring that flow across the restriction is liquid. Control is also achieved by maintaining the temperature of the cryogen delivered from the outlet low enough to avoid detrimental flashing.
