Claims16
In electrostatic spray coating, apparatus having a self contained electrical power supply devoid of external electrical connection thereto, means for converting the kinetic energy of a moving air stream into electrical energy comprising,
- rotatable turbine means having a low moment of inertia peripherally exposed to a stream of air moving at high speed for converting the kinetic energy of said stream of air into kinetic energy of a rotating mass,
- alternator means having a low moment of inertia and a common axis of rotation with said turbine means and directly driven thereby,
- said rotatable turbine means and alternator means jointly constituting a composite low moment of inertia rotatable means accelerable from rest to an operating speed of over 10,000 r.p.m. in less than 1/4 second for rapidly converting the kinetic energy of said stream of air into alternating electrical energy suitable for use as a primary electrical power source for said electrostatic spray coating apparatus.
In electrostatic spray coating apparatus having a self contained electrical power supply devoid of external electrical connections thereto, means for converting the kinetic energy of a moving air stream into electrical energy comprising,
- an impulse type air motor having a low moment of inertia for converting the kinetic energy of a moving air stream from a remote source thereof into kinetic energy of a rotating mass and
- alternator means having a solid magnet armature of low moment of inertia and magnetized across a diameter thereof, disposed coaxially with said air motor and directly driven thereby,
- said air motor and alternator means jointly constituting a low moment of inertia rotatable mass accelerable from rest to an operating speed of over 10,000 r.p.m. in less than 1/4 second for rapidly converting the kinetic energy of said stream of air into alternating electrical energy suitable for use as a primary electrical power source for said electrostatic spray coating apparatus.
Energy conversion apparatus for effecting the rapid conversion of the kinetic energy of a moving stream of air into electrical energy comprising,
- a perimetric housing defining a pair of coaxially aligned cylindrical chambers therewithin,
- rotatable turbine means having a low moment of inertia disposed in one of said chambers,
- alternator means having a rotor with a low moment of inertia on a common axis of rotation with said turbine means and adapted to be directly driven thereby disposed in said second chamber,
- said turbine means and alternator means jointly constituting a composite low moment of inertia rotatable mass accelerable from rest to an operating speed of over 10,000 r.p.m. in less than 1/4 second,
- means for directing a stream of air moving at high speed into said first chamber into driving engagement with said turbine means to convert the kinetic energy of said air stream into kinetic energy of rotation of said turbine means and alternator rotor,
- and stator means included in said alternator means and forming at least a portion of the defining walls of said second chamber for converting the kinetic energy of said rotating rotor into electrical energy.
