A DC electric motor system includes a rotor portion having a commutator and a coil winding mounted radially about a shaft, and a stator portion including two rows of spaced permanent magnets about either side of the rotor coil winding. Pick-up coils are mounted about the circumference of the electric motor to pick up energy produced by the change in magnetic flux about the edges of the rotor coil winding. The pick-ups coils transfer the collected energy as current for use in charging a battery within an electric vehicle, or the like.

A rotary Wankel type engine system is disclosed, wherein the crankshaft is supported by a center main roller bearing. The rotor apexes are sealed by two piece apex seals and by side seals. The engine system further includes an oiling system which permits oil flow through the center bearing and through lubrication passages in the engine rotor to provide a means for cooling the engine rotor under high loading conditions. Riblets are defined in the combustion face of the rotor to promote aerodynamic lateral stratified charge control to minimize atomized fuel charge loss to surface wetting before ignition.

A propeller blade element which virtually eliminates stall conditions. The rotatably driven blade element employs a long straight extended sharp leading edge from hub to tip, without helix, to insure blade laminar fluid flow without vortice formation or leading edge stagnation. The extending leading edge provides separated upper and lower laminar air flow to a 'C' shaped blade configuration. The blade element in one form employs a proportionally upwardly curved trailing edge which provides accelerated flow of the high pressure air on the face of the blade, thus increasing the thrust over conventional blade elements.

Aircraft propeller and blade element

An aircraft propulsion assembly in which a prime mover drives a rotating air stream generating element, situated in a generally circular housing that supports a ring shaped stator in which a number of circumferentially spaced slots are defined. An elongate nozzle is axially aligned with the rotating element, which nozzle on the forward end in cooperation with the housing defines a circular plenum chamber that is in communication with the slots. The plenum chamber on an inner portion thereof cooperates with the stator to define a circular aperture. A first portion of the air stream generated by the rotating element flows rearwardly through the nozzle and a second portion through the slots in to the plenum chamber to be compressed. The compressed air excapes from the plenum chamber through the circular aperture, and due to the Coanda effect flows along the interior surface of the nozzle as a cylindrical sheath at a higher velocity than the first portion of the air stream flowing rearwardly through the nozzle. As a result, the first portion of the air stream is not subjected to any appreciable drag resistance and exits from the nozzle at maximum velocity to impart maximum forward thrust to the assembly.

A relatively simple gear-forming process is disclosed, which enables the production of a set of gears that is especially useful for a particular type of gear pump, and which also produces a set of gears which operates with a high degree of rolling contact. The gears are produced by first forming an initial cutter gear having teeth with cylindrical tips supported by narrow supports, and using this initial cutter on a gear shaper to cut a first gear having bullet-shaped teeth. The first gear can then be used as the cutter on a gear shaper to cut other gears with bullet-shaped teeth or to cut gears with pole-shaped teeth. In a gear pump wherein fluid is forced through an axial passage opening into the space between teeth of the sun gear, the sun gear is formed with pole-shaped teeth while the planetary gear is formed with bullet-shaped teeth.

Gear pump, gear and method

An electric motor including a rotary armature and an annular field mounted for rotation around said armature and geared to said armature by way of planetary gearing fixed to the housing whereby the opposing torques of the field and the armature are summed at the motor output shaft. Such counter-rotating field arrangement provides for an increase in the flux cutting speed of the motor while, at the same time, maintaining the angular rate of the armature at a speed which is compatible with the containment of the centrifugal forces thereof. Both the armature and the field include concentric commutation rings at one end of the motor such that the field coils and the armature coils are excited at a predetermined phase angle by a plurality of field and armature brushes. Disposed along the field and armature brushes, and separated therefrom by at least one commutation segment are corresponding pick-up brushes which receive the collapsing field transient of the individual coils in both the armature and the field. These pick-up brushes are, in turn, connected to an amplifying device thereby restoring some of the energy losses back to the power source for the motor.

Counterrotation electric motor

An anti-pollution nozzle assembly that removably engages the fuel inlet tube on an automotive vehicle and removes fuel vapor from the tank thereof at a rate that varies with the rate at which fuel is discharged into said tank by said nozzle assembly, with the removed fuel vapor being returned to the fuel storage tank of the service station where the anti-pollution nozzle assembly is employed.
