A flash tank configuration for an economizer is provided that is inexpensive and simple to construct, reliable to operate, and efficient for use in an economizer compression refrigeration system. The configuration includes an upper baffle and a lower baffle configured and arranged within the flash tank so as to separate the liquid and gas phases of intermediate pressure refrigerant, and to convey each phase to other components in the refrigeration systems. The flash tank has a generally cylindrical shape, and is dimensioned so as to provide adequate internal volume for expansion of refrigerant to a desired pressure, separation of the resulting refrigerant gas and refrigerant liquid phases, and temporary storage of the refrigerant phases before conveying the liquid phase to the main refrigerant line between the condenser and the evaporator, and returning the gas phase to the compressor. Additionally, methods are provided for using the flash tank to separate refrigerant phases.

A rotary machine having a housing with rotary components disclosed within. The rotary machine is configurable as an internal combustion rotary engine, an external combustion rotary engine, a gas compressor, a vacuum pump, a liquid pump, a drive turbine, or a drive turbine for expandable gases or pressurized liquids. The combustion engine employs a new thermal cycle—eliminating the Otto cycle's internal compression of the combustion products as part of the cycle. The new combustion thermal cycle is intake, expansion and exhaust.

A circuit is provided to provide instruction streams to a processing device: embodiments of the circuit are appropriate for use with RISC CPUs, whereas other embodiments are useable with other processing devices, such as small processing devices used in a field programmable array. The circuit receives an external instruction stream which provides a first set of instruction values, and has a memory which contains a second set of instruction values. Two or more outputs provide instruction streams to the processing device. The circuit has a control input in the form of a mask which causes a selection means to allocate bits from the first and second sets of instruction values to different instruction streams to the processing device.
