Abstract

Abstract This application discloses a permanent Air Rectifier with Process which centrifugally separates coarse contaminants through escape ports with some air from a pressured air flow passing through at least one confined narrow curved channel having windward vertical sidewall baffles therein. This cleaner air being then radically reversed, inertially dislodging additional particles, before passing through enclosed narrow oil soaked corrugated walled channels where extreme turbulance removes finer contaminants by contact cohesion or electrostatic attraction to said corrugated walls, which walls are capillarily oil soaked from an oil filled porous sump, said air being again reversed into a turbulance chamber completing the process.

Claim 6
Dependent Claim 33 words
The apparatus of claim 6 in which said corrugated paper attractor element strips are vertically crimped into larger convolutions so deposed as to create turbulance in the air flow as it passes therethrough.
Claim 7
Dependent Claim 668 words
An Air Rectifier for the removal of both micronic and sub-micronic solid contaminants, such as dirt, mud, hail and snow, as well as liquid contaminants such as rain, oil and water from an air stream flowing therethrough, said apparatus comprising; a unitary essentially circular body structure composed of solid non-porous material such as sheet metal, having a removable lid, said unitary body structure also having a floor with upwardly positioned vertical wall structures solidly articulated thereon, said wall structures extending upwardly to the lid of said apparatus so positioned and deposed as to form between said floor and said lid three distinct essentially concentric bottomly liquid tight operational divisions in said apparatus; the outermost division, the intake channels, being essentially horseshoe shaped and being positioned on the two lateral sides and the rear of the next inwardly positioned division, and being fully opened on the forward ends thereof, said outer division containing a multiple number of narrow crescent shaped inlet channels, these channels formed by bottomly articulated vertical walls which extend upwardly to the lid, spaced within said intake channel, said narrow inlet channels having fully opened forward ends thereon and a multiple number of side-wall baffles with at least one bottomly positioned escape port at each baffle in each of said inlet channels, said channels converging together from each side at the rear of said apparatus, said channels also having escape ports in the floors thereof at the points of convergence, said channels also having at the points of convergence, air flow wall ports in the upper portion of the inner wall thereof, the outermost port opening into the second inwardly positioned channel, the second inner wall port opening into the next inner channel and finally the last inner wall port opening into the second major division of the apparatus, the element chamber, said element chamber being doughnut shaped and having fully circular side walls, the lower portion of said walls being liquid tight thus forming a sump portion therein, said chamber being fully filled with an upwardly channelled element, said element consisting of absorbent material such as corrugated paperboard or the like, said element being formed of a multiple number of concentric full height strips or baffles of said paperboard, said baffles being separated at the lower portion thereof by fully concentric sections of honeycomb-like material such as vertically positioned corrugated paperboard, said honeycomb section of said element being filled with oil or the like and being confined to the sump section of said element chamber, this formulation then consisting at the upper portion of said corrugated baffles above the honeycomb of narrow crescent shaped channels, the corrugated side walls of said channels having two cutaway sections at least part way down from the top thereof, one at the intake channel port, and the other at the exact opposite side at the port entering the turbulance chamber, said cutaway sections to facilitate the air flow from the intake channels, through the element channels, into the next inwardly positioned portion of the apparatus, the turbulance chamber, through an upwardly positioned port in the inner side wall of said element chamber; said turbulance chamber being positioned immediately inward from said element chamber having a common wall therewith, said wall having an upwardly positioned port therEthrough, said chamber being doughnut shaped, and having at the center of the floor thereof an outlet port, said outlet port having a tubular flange articulated therethrough; said flange extending downwardly from the floor of said chamber to provide articulation to the motor intake and upwardly the full height of said chamber to the lid of said apparatus; said tubular flange having an upwardly positioned exit port on the side opposite the inlet port from the element chamber through which port and flange the air stream may pass from the apparatus into the motor after it has passed on both sides of said tubular flange and met head on in a reverse flow at the rear of the turbulance chamber and the tubular flange.
Claim 8
Dependent Claim 588 words
An Air Rectifying Process which in conjunction with an appropriate apparatus rectifies air by removing both micronic and sub-micronic solid contaminants, some of which are ionized, as well as liquid contaminants from an air stream passing through said apparatus, which air at great speed and in over supply under forced motion from the motor fan and the forward movement of the vehicle enters a multiple number of curved inlet channels which are integral with and positioned on opposing sides of said apparatus and passes therethrough, wherein heavy contaminants including water or snow are forced outwardly by centrifugal and inertial forces to the outer walls of said curved channels, where some cohere to said walls by cohesion or electrostatic attraction and where some move along said walls and finally pass behind outer side-wall baffles and on out of said apparatus with a small amount of air through escape ports behind said baffles in the floor of said channels, the cleaner remaining air then collids head-on from opposing sides of said apparatus with great turbulance and inertial force as it makes an abrupt turn to enter the inwardly positioned oil soaked and corrugated walled channels which are positioned in an element chamber in said apparatus, said air at said turn, by strong inertial forces dispells additional contaminants which are also purged with a small amount of air through exit ports in the floor of said apparatus, said remaining air then passes through said curved narrow oil soaked, vertically corrugated walled channels in the said element chamber during which passage said remaining contaminants, either dry or wet, micronic or sub-micronic are forced outwardly by centrifugal force to contact said oil soaked walls to be surface cohered or electrostatically attracted to said walls, this latter by virtue of natural ionization, also as the air flows through said corrugated walled channels, where severe aerodynamic turbulance occurs in said air stream due to the curvature of the channels and the convolutions of the corrugations in the wall thereof, severe eddying is created in the air as it whirls about said convolutions where small patterns of centrifugal forces thrust said contaminants against or very near said oiled walls causing them to cohere or be electrostatically attracted thereto, here said captured contaminants are then sheltered from the force of the main stream of the air flow as they are held by oil bonding in the valleys of the convolutions where they have sufficient dwell time to settle downwardly by gravitation into the bottomly positioned honeycomb oil filled sump of the apparatus, said air streams, at the end of said channels, again meet head-on from opposing sides and are radically reversed again dispelling contaminants by centrifugal and inertial forces into the sump area where said contaminants are held by an oil coating on the honeycomb, said air stream then enters a turbulance chamber where it divides and passes about a baffle at the throat of the outlet on both sides thereof thus coming head-on again with great turbulance in the turbulance chamber where as before inertial forces cast out heavy contaminants, before the air stream is again radically reversed, thus again dispelling contaminants including any air-borne droplets of oil or water tO the oil coated floor of said chamber before entering the exit port and flange passing out of the apparatus, thus by the processes of centrifugal force with purging, inertial force with purging, aerodynamic turbulance and eddying with surface cohesion, oil bonding, electrostatic attraction and gravitational sedimentation essentially all contaminants are removed from said air stream.
