Abstract: A fluid pump which uses a motive fluid for pumping liquid or gaseous fluids by use of a fluid inlet, a fluid exchange chamber, and a fluid exhaust means operates as follows: A fluid which is to be pumped is introduced into a fluid exchange chamber. The exchange chamber then isolates itself from the fluid source. Now a motive fluid is introduced to the exchange chamber. The fluid which is to be pumped is carried away from its intended use while the motive fluid displaces the previously existing fluid in the exchange chamber. The exchange chamber is then exhausted of its motive fluid contents and more fluid which is to be pumped, is once again introduced to the exchange chamber to repeat the cycle.

Abstract: A moveable, ovoid body for incorporation in and with the conventional elements of a turbo jet and possessing compressor and diffuser shape characteristics that are found in turbo jet machines. The invention is designed to take the place of conventional diffusers which are employed in both compressor and turbine stages of turbojets. When used with the hydrovapor engine, developed by the inventor, the moveable diffuser shell which operates in conjunction with impeller and turbine propeller blades offers a wide range of selectable operational parameters such as inlet flow velocity, compression chamber pressure and exhaust velocity.

Abstract: A method and apparatus for ejecting fluids through use of a high pressure liquid motive fluid by forming hydraulic slugs from said motive fluid and conducting it through conventional ejection mechanisms, entraining a fluid which is to be ejected and depositing it into containment of user's choice. A pulser apparatus is employed which embodies the concept of abruptly starting and stopping high pressure motive flow, contemporaneously constricting the downstream flow through use of either inlet or instream interruption means, and entraining quanta of fluid to be ejected, said entrainment being the urging of said discrete quanta by the momentum of a series of hydraulic slugs formed by the aforementioned method.
