Title: GAS CUSHION BASE MOR CONVEYORS OR TRANS~PORT MEDIUM4 The invention relates to a gas cushion support structure to be used as a conveying or transporting system whereby a gas permeable upper structure forming the roof section of the plenum chambxcr supports movable load members in a frictionless state on a cushion of gas forme~d by low pressure gas emit ting from surface orifices of the porous diffuser me~ans as the gas perneable structure of the i ,iain structure.
The device of the invent-ion prov'ides an efficient mreans of mocving goods or people from one point to another by utilizing a continuous belt, platforms or structures as individual units or as continuous, linked or joined mrovable load memb~ers. The invention is characterized by a gas per;Tiable upper structure of the main structure housing the pressurizable plenum chamber or chambers. The gas pressure generated by fans or the like pressurize the plenum chamber or chambers causing gas to pass through the plenum chambers roof section forned as the permeable upper structure.
This upper structure is composed of a porous diffuser mnans which acts to baffle the entraining pressurize gas to lower its velocity on release from the surface passages to form a low pressure cushion of gas localized adjacent to thle surface of this structure to provide the gas cushion support means to float moalela members in a rciols state clear ofteuprsraeof h a emal upper stutr sthle main support area.
The invention has been devised to provide a novel frictionless gas cushion surface to support mnxabl(k load nembers, floating on a pressurized cushion of gas ema~nating from the porous diffuser means.
The device of the invention mny be produced in an economical manner and readily put into service. Miurther advantages will be aparrent from the following description.
The invention would havo wide and varied use to provide efficient low cost goods mni people transport, materials and goods handling and conveyor systems, pedestrian travelling foot ways and transport carriage ways, sports gwzt*s and amusement fun rides.
For such activities previous known pressure gas jetting conveyors depended on a straight row of clear through gas jetting orifices located along the centre line of the pressurized gas support structure to support the continuous length of the conveyor belt system. The jetting orifices ran right through to the gas pressured plenum chamber. Pressurized gas issuing frcm these jetting orifices diffused under the spread area of the conveyor belt to provide gas cushion lift to support the load. With the known system clear through orifices forming the jetting mans are covered by the belt for the full jetting area. Gas diffusion depends on the belt moving to carry the emitted pressurized gas forward to spread in its effort to support the load carrying conveyor belt. At rest or slow running friction spots occur, especially prevelant when uneven or impact loads are applied to the system. Clear through orifices used in the pressure jet system could not effectively be applied to large areas or carriage ways whereby one or mocre movable load members would only cover a part area of jetting array.
The system would be i~oisy and impractical, consuming copious amounts of pressurized gas from the under based plenum chambers.
whereas with the present invention individual. or adjacent plenum chambers can be pressured by the variable pitch means of their fan systems 20 only when needed in a progressive manner. By utilizing the baffling action 0 0 00 of the porous diffuser means built into the gas porable upper structure, pressurized gas supplied from the under plenum chambers is economically released from the surface passages of the gas permeable upper structure at a controlled low velocity cLascharge to support located mvable load members floating on a pressurized cushion of gas.
It can be summrarized from the foregoing the major difference between the known jet conveyor system and present invontion. With the known k :6ystem pressurized gas jetting from open cloar through orifices under thle conveyor belt are diffused between the base structure surface and the underside of the mo~ving conveyor belt.
Whereas with the present invention diffusion of the pressurized gas passing from the plenumn chaimber occurs within the porous diffuser me~ans of the permeable upper structure. Baffling results in a lower velocity of 2 aa~ 0 s emission thereby maintaining an effective gas cushion support layer between the plenum chambers higher gas pressure and the sealed underside of the movable load member.
Embodiments of the invention are characterized by the following: The invention is comprised of at least one main structure housing at least one gas pressurizable plenum chamber equipped with at least one gas pressurizing means whereby the roof section of said gas pressurizable plenum chamber form the gas permeable upper structure whereon at least one movable load member rides in a frictionless aerostatic state on a load support cushion of gas emanating from layrinth-like passages of a porous diffuser means.
Roof section of the gas pressurizable plenum chamber formed as the gas permeable upper structure comprises said porous diffuser means.
Porous diffuser means formed as the dimensional body component of the gas permeable upper structure provide two purposes whereby its design feature provide the necessary support strength to meet needs of its own load function support including, the load support requirements of the Srovable load member. The other requirement of the porous diffuser means 00 related to its dimensions and construction features are to provide by the 0 use of type and arrangement of specific materials used in its construction to act as a static gas flow resistance element to diffuse and lower velocity of pressurized gas escaping from the under gas pressurizable plenum chamber by way of the myriad of labyrinth like passages incorporated in the specific structure of the porous diffuser means.
S* Features of the porous diffuser means relate to dimensions and construction using specific types of materials and method of fabrication arrangements.
Dimensional body forming the gas permeable upper structure housing the diffusing means position as the roof section of the gas pressurizable plenum 30 chamber. Design would incorporate structural support means in combination with the dimensions and construction of the porous diffuser means.
3 i v Gas porousity factor necessary to maintain the required gas cushion load support me~ans to support the movable load me~mber aerostatically in a frictionless state on the main support area surface would be determined by the specific materials used and the dime~nsional thickness of the porous diffuser body.
Gas porous ity factor would be formulated by the size and length of the gas passageways to govern gas flow through the porous diffuser mans. Needs of specific gas cushion load applications would dictate type and design of specific porous diffusing means.
Dimensions and constr-uctions or porous diffuser mans may consist of the following: Bonded dime~nsional sized parts of materials held in an open porous state composed of a material characterized by formastion of plastic, wood, mretal, concrete and rock aggregate whereby bonding of dimensional sized parts of material. occurs at their touch points so as to maintain open gas passageways through the bulk form of the material wherein the labyrintha like passages convey gas from the gas pressurized plenum chamber to emanate from openings in the main load support area surface of the gas permeable upper str-ucture to provide the load support cushion of gas.
Alternatively porous diffuser means may be formed within the dimensional body of the gas permeable upper structure whereby a sandwiched layer structure of gas permeable material characterized by formations of mtal, fibreglass, synthetic fabrics, synthetic materials, rubber, wood, vegetable matter.
In either option these materials would be arranged to act as a static resistance element to limit flow of pressurized gas flowing from the plenum chamber to emanate from openings in the main load support area surface of the gas permeable upper structure to provide the load support cushion of 0 6 gas.
Arrangements of the invention relating to an assemblage of main structures as a gas cushion support structure would be applied to transport A( carriage-ways, nulti-conveyor system or large areas whereby a series of C 4 /Cr.3 main structures would assemble in a linked formation relationship to form one continuous structure, or as adjacent grouped formation to form large areas. Each progressive main structure would house at least one gas pressurizable plenum chamber equipped with at least one gas pressurizing means such as a powered fan equipped with pitch variable rotor blades actuated by a servo means responsive to an adjacent control means responsive to a sensing mrans positioned strategically to mronitor the position of at Jeast one moveable load me~mbers supported aerostatically on a cushion of gas emanating from the min support area surface of the gas perrreable upper structure.
Assemblage of main structures as adjacent grouped formation would form larger areas whereby multiple gas pressurizable plenum chambers would have individual gas pressurizing means as either fixed bladed fans or as upward fans equipped with pitch variable rotors blades actuated by a servo means responsive to a control mans. Sensing mans my consist of any of the known devices related to surface based induction loop, electromagnetic radiation or piezo electric. Signal generated at sensing me~ans would pass to the control means controlling pitch variable function of fan rotor blades by operatLion of a servo means incoiporated therein.
