Abstract: A system for processing a natural gas stream includes a flow-through turboexpander generator, a throttle valve, a knockout separator, and an absorption separator. The flow-through turboexpander generator is configured to receive a first portion of the natural gas stream and generate electrical power in response to expansion of the first portion of the natural gas stream. The throttle valve is configured to reduce a pressure of a second portion of the natural gas stream. The knockout separator is configured to receive the first portion of the natural gas stream from the flow-through turboexpander generator and configured to separate phases of the first portion of the natural gas stream to produce at least a gaseous phase and an aqueous phase. The absorption separator is configured to receive the gaseous phase from the separator vessel and separate water from the gaseous phase to produce a dehydrated natural gas stream.

Abstract: A modern scenic passenger railcar system is disclosed. The railcar system incorporates design and safety features of modern freightcars and modern passenger scenic railway cars. The railcar system incorporates a center beam with a square cross section as well as specialized crash posts with its frame. This results in enhanced safety and crashworthiness. The railcar system also incorporates cross members for absorbing and distributing shock and mechanical stress on the railcar system during use, by withstanding torsion and shear forces on the frame. This results in improved mechanical integrity of the frame and the railcar system overall.

Abstract: A foot activated grill opening apparatus and method for reducing the chance of user injury and eliminating awkwardness when opening and closing the cover of a grill. The apparatus allows a user to open the cover of a grill in a hands-free fashion. The present invention allows a user carrying utensils and plates in both hands to still open and close the cover of a grill. Additionally, the apparatus further reduces the chance of user injury from contact burns, radiant heat burns, grill flare-ups, and the like that may occur when a user reaches across and above a grill's heat source while opening and closing a grill cover in a conventional manner. The present invention further provides aid to elderly and weaker individuals incapable of either lifting the weight of the grill cover or generating the necessary shoulder/arm range of motion to open the grill cover.

Abstract: A sequence of series-connected transformers for transmitting power to high voltages incorporates an applied voltage distribution to maintain each transformer in the sequence below its withstanding voltage.

Abstract: A method for operating a cryocooler which provides opportunity for timely intervention prior to failure thus enhancing the reliability of the provision of the refrigeration wherein contaminant concentration downstream of a compressor but upstream of the cryocooler is monitored and the time rate of change of the contaminant concentration is used to calculate a service time.

Abstract: A method for operating a cryocooler which provides opportunity for timely intervention prior to failure thus enhancing the reliability of the provision of the refrigeration wherein temperature trending of at least one cryocooler component or the refrigeration load is monitored and used to calculate a service time.
