"This invention relates to aircraft propulsion systems and power units. Whilst it is intended primarily to be applied to propulsion aircraft systems in which thrust is developed by reaction arising out of the expulsion of a stream of gas through a nozzle or jet, and this is deemed to be the application which uses the features of the invention most advantageously, yet it may be found that some or all of these feature may also usefully be employed in power units for generating shaft power; or where it is required to produce a source of gas possessing considerable energy in the forms of velocity, pressure and heat, for example for driving turbines."
The patent act of 1790 established the rules for submitting a patent application. Each application had to be submitted with specifications, a patent drawing, and if possible a model of the invention. Eventually, models were no longer required.
