摘要： A sliding capo for rapid changing of the pitch of musical instrument strings. The capo comprises a bar assembly for extending across and engaging the strings on the neck of an instrument, and a spring assembly connected to opposite ends of the bar assembly and extending across the back of the neck of the instrument for pulling the strings into contact with the frets of the instrument.

摘要： A regenerative heat exchanger for transferring heat from the exhaust gas to the intake working fluid of a prime mover and from the pressurized working fluid to the exhaust vapor of a heat pump. Application is especially useful in a system in which liquid air or nitrogen made by a heat pump provides compression cooling for a gas turbine prime mover. The heat exchanger employs circulating element heat transfer surface such as wire belts or ceramic balls, which circulate in turn through working fluid exhaust and intake channels while absorbing and rejecting heat between the two channels. Effectiveness exceeding 98% increases thermal efficiency of small low-pressure ratio gas turbines.

摘要： A gas turbine prime mover for stationary and motor vehicle application. The gas turbine employs jet compression energized by a pressurized motive fluid to entrain a depressurized suction fluid from the turbine discharge. Combined suction and motive fluids circulate through the combustor or other heating source and the turbine while motive fluid, separated from the turbine discharge, preheats pressurized motive fluid in a heat recovery recuperator or regenerator. Additional features include recovery of heat loss from heating source loss and sub-ambient compression cooling of motive fluid. Cycle efficiency of 70% is attained.
