Abstract: A liquid fogging apparatus has a motor which operates from the 12 volt power supply of a vehicle and delivers high torque at high speed, operating aproximately at 0.2 horsepower at 28,000 RPM. A rotating ring of porous ceramic material atomizes the liquid. The motor is small, 1.6" in diameter with a 5/8" diameter rotor. The stator has four phases each preferably containing eight three-turn windings of four strand wire, wound in slots in the outer surface of a short laminated stack, which is reinforced in epoxy with its inner surface honed to minimum thickness to reduce flux leakage. Eight bipolar permanent magnets are set in axial slots of a rotor stack with like poles facing tangentially toward each other around the rotor shaft. A controller commutates the motor sensing back-EMF on the windings to control speed and detect motion during start-up.

Abstract: A housing for enclosing a power source for operating an implanted artificial organ is provided. The housing has an annular rim defining an aperture and is mounted in the human body such that replacement of the power source through the aperture is effected from outside the body without resort to surgical means. The housing is secured in the body by attachment to internal tissue, preferably bone.

Abstract: A jet blower having a housing, a cylindrical chamber, a blower wheel in the chamber, four tangential passageways from said chamber, the passageways terminating in axially-directed nozzles and a Venturi foil surrounding each nozzle.
