Abstract:

A method of effecting the in-flight departure of an astronaut from a shuttle craft, and apparatus therefor. A plurality of rocket assemblies with a lanyard for each are provided, although only one rocket assembly is used for one escape. The astronaut is carried in a parachute harness which is selectively connectible by the astronaut to one of the lanyards. A safety lever is moved when the astronaut pulls the lanyard. An ignition system is subsequently actuated when the lanyard is pulled further by the astronaut. Two rods push their corresponding rocket out through the side hatch of the shuttle craft. When the lanyard grows taut, one means fires the rocket. Subsequently, other means pull the parachute ripcord.

Abstract:

An improved system and method for liquefying natural gas employing liquid nitrogen is disclosed. The improved system and method lowers the nitrogen consumption rate by using an expander, for example, a radial inflow turbo-expander, on the nitrogen side. This reduction in nitrogen consumption rate substantially reduces system operating costs.
