Abstract: A method is disclosed for cooling, condensing and subcooling a substantially single component gas stream by passing the gas stream through a heat exchange relationship with a vaporizing multicomponent stream so that carry-up of the condensed liquid phase is maintained without condensed phase backmixing and pot-boiling of the coolant stream is avoided. The single component gas stream is passed through a cold-end up heat exchanger having a serpentine pathway for the gas stream comprising a series of horizontal passes separated by horizontal dividers and alternatingly connected by turnaround passes at each end. The method is particularly applicable to the condensing of a recycle methane stream in a nitrogen rejection process which uses a methane heat pump cycle to provide refrigeration.

Abstract: The device of this invention is intended to reduce the possibility of inflammation of the muscles in the vicinity of the elbow resulting from prolonged gripping by the user of the handles of tools, tennis rackets or the like. The device is designed to support the little or fourth finger of the hand being used to grip the handle, maintaining the finger in a slightly crooked condition and well out of contact with the handle while the remaining fingers actually contact and grip the handle.
