  • One possible construction method is to have a flat plate of length equal to the circumference of one or the other of the outer or the inner shell, and have cut out sections that allow bending or popping out of elements that can direct the airflow. After construction of the plate with the cutouts, which may be done with water jets or other cutting mechanisms, the popout sections are bent out (or bent in depending on whether the flat plate is positioned next to the inner or outer shell). Thereafter, the flat plate is bent to follow the circumference of the fire, along the inner or outer shells as chosen.

  • Other embodiments will in addition be configured to have distribution ducts 21-026 along the edge of the seatback on one or both sides of the head with vents 21-028 along those distribution ducts, thereby distributing the airflow around the head.
  • Some such embodiments will have adequate airflow to ensure a positive pressure region 21-022 around the head and face so that the head and face is surrounded by fresh air, which drives out stale air from the region because of the positive pressure created by the supply of air through the air duct and distributed around the head.
  • a positive pressure region will require a sufficient pressure gradient between the surrounding air in the cabin and the air supply through the vents.
  • the positive pressure region around the head is improved with a shield or hood eg 21-023,21 -024, around the head region of the backrest.
  • Such a hood would be in most embodiments be sealed with respect to airflow around the head section of the head section of the backrest, and be impervious to the flow of air, so that there is no leakage of air out of the positive pressure region around the head and face. Such a hood will move with the backrest, thereby ensuring that the positive pressure region is maintained regardless of the position of the seatback. Some embodiments may also have an extended hood so that even if the occupant leans forward from the seatback the positive pressure region is maintained around the face and head. Some embodiments may have sections of the hood transparent, so that the occupant does not feel claustrophobic. The hood may be semirigid or flexible.
  • Some setbacks may have apertures openings which will need to be sealed in some embodiments with regard to airflow for the positive pressure region to be effective.
  • the air supply needs to have adequate pressure and volume to be able to maintain the positive pressure region around the head and face, for all the passengers in the aircraft. This could have an impact on safety measures with regard to airborne or aerosol borne pathogens such as viruses. Clean air adequately free of pathogens for the safety of occupants will be ducted through the air supply system to the occupant supports and their own air supply ducting.
  • the flow rate of air needs to be maintained at a minimum level to ensure that the positive pressure region is maintained.

This will be by switching to the real time stream from the archive recordings to the real time when the loop has been played upto the present time at faster than real time speeds.

Therefore, as one half saddle moves forward and upwards the other moves backwards and downgrades thereby creating a support for the upper leg based on the position of the lower leg and vice a versa with the positions of the legs are reversed as a move along the circumference of the pedal circle.

  • this fire pit architecture will heat the air in the annular air jacket so that it projects out at the top.
  • Other fire pit designs simply allow the air to flow vertically upwards out of the top of the annular jacket, either with or without a ring to direct airflow slightly inwards towards the fire. While this architecture works well, it is improved substantially by creating a vortex of air discharged from the top of the jacket by discharging such air at an angle so that such air projecting outwards forms a vortex with the hot gases from the fire and contains a fire more efficiently and raises the temperature of such contained gases, resulting in better combustion.
  • the vanes are positioned to direct the airflow in the annular space around the fire between the inner and outer shells.
  • the air is directed at an angle, the project out of the top edge at an angle and therefore create a vortex of gases that improve combustion of the fire.
  • the top ring may also have such vanes that direct airflow at an angle.
  • Some embodiments may have both vanes in the body and the operating, or may have such vanes in one or the other.
  • some embodiments may have a protrusion to the fire area with air vents raised above the grate. Such a protrusion may have a roof that protects it from falling ash entering the air channels below.
  • Some embodiments may also have air vents below the grate to feed residual unburnt materials on the grate.

  • One possible construction method is to have a flat plate of length equal to the circumference of one or the other of the outer or the inner shell, and have cut out sections that allow bending or popping out of elements that can direct the airflow. After construction of the plate with the cutouts, which may be done with water jets or other cutting mechanisms, the popout sections are bent out (or bent in depending on whether the flat plate is positioned next to the inner or outer shell). Thereafter, the flat plate is bent to follow the circumference of the fire, along the inner or outer shells as chosen.
  • the electrostatic fibers attract the droplets in the aerosols with a viral load, and therefore deposit the viral load on the fibers.
  • the virus is not killed or deactivated and can mobilize again when the electrostatic field is diminished,
  • the virus in its normal aqueous medium has a phospholipid bilayer with its hydrophilic ends of the outer layer of the bi-layer attracted by the water molecules and facing outwards, and the hydrophobic non-polar tail inward facing and next to the tail of the inner layer molecules, which in turn point their hydrophilic heads into the virus or the cell.
  • the molecules are held together by Van der Waal forces that allow the molecules a lot of flexibility of movement and in fact the molecules actually migrate around and change neighbors - more so in the liquid state but also in the gel state. So the upshot is that they are not rigidly bound to have any particular orientation except what the environment dictates.
  • the outer molecular layer of the phospholipid bi-layer of the virus skin will no longer present the hydrophilic polar ends on the outside as there are no water molecules to attract.
  • the outer layer phospholipid molecules will therefore be disorganized.
  • the hydrophobic non-polar oil or triglyceride molecules will have similar structure to the non-polar tails of the phospholipids and will attract those non-polar hydrophobic tails of the outer layer in the bi-layer. So the top layer organization of molecules will be further disrupted. This in turn means that the inner layer hydrophobic non-polar tails will no longer have the exclusive access to the non-polar tails of the outer layer molecules.
  • the phospholipid bilayer molecules are likely to self assemble as micelles with the hydrophobic ends on the outside next to the oil and the hydrophilic ends along with the glycoprotein spikes on the inside thereby rendering them useless in addition to stripping the virus of its lipid membrane. It is also possible that the inner layer of the bilayer will remain intact but without the glycoprotein spikes which would be stripped away with the outer layer, therefore rendering the virus inactive.
  • the use of oil as a film or sheath around the electrostatic fibers offers a defense against moisture contacting the electrostatic fibers. As noted before oil is a nonconductor (of course this excludes oils with conductive additives), and therefore will protect the electrostatic charges on the fibers. Moreover, charges generated by friction between fibers will continue in the presence of oil.
  • the high dielectric constant of oil will in addition increase the electrostatic field at the surface of the oil for attracting aerosol particles as compared to having simply air around the electrostatic fibers.
  • the aerosol droplets of water (containing the a viral load) that deposits on the oil layer will slowly evaporate , in the presence of air and particularly air with a velocity as in the air channels of the mask. This will result in the virus increasingly deprived of its water substrate - the virus if its integrity is to be maintained cannot evaporate - and be forced to contact the surface of the oil. The electrostatic attraction will augment the captive forces on the virus. This will result in the mechanism noted above that will destroy the viral phospholipid bilayer and destroy the virus.
  • the non-polar compounds such as the oils used can even be waxy solids at room temperature. Even if a solid or waxy oil/fat is used the virus will be forced to cling to the surface and be killed.
  • This invention is a treatment of electrostatic fibers used in masks to have a sheath or layer of oil. Some embodiments may use other non-polar liquids or gels.
  • the fibers may be coated with oils and fats or other nonpolar materials.
  • oils and fats or other nonpolar materials First they may be deposited for higher boiling point substances by maintaining the electricity fibers at a lower temperature while infusing the region of their presence with vaporized oils.
  • they may be dipped in the oil or the more than wax if the material is solid at room temperature.
  • they may be sprayed with the oil.
  • the benefits of a high viscosity oil or a solid oil/wax, is that it will remain in place as a sheath on the fibers for a longer period of time.
  • the fibers may be treated as noted with the oils either ahead of assembly into structures used in the masks or they may be treated after creating the appropriate inserts or shapes using the masks.
  • Masks for controlling the viral load inhaled have become pervasive for very good reasons.
  • the difficulty with masks worn on the face is that human communications are impaired resulting from a lack of visibility of the face and facial expressions which are critical for effective communication.
  • the present invention addresses this problem but at the same time addresses an important architectural feature of facemasks to ease breathing.
  • respirators are available in the market. They use valving mechanisms for incoming air and outgoing air. Incoming air is filtered through filter pads that is well disclosed in the background art and then go through a valve (the inhale valve) which opens to allow air to flow in but closes to prevent air from going out.
  • an embodiment of this invention also adds a filter to the exhaled air thereby protecting third parties from potential pathogens that are exhaled by the user. Such fitters will be mounted adjacent to the exhaled valve.
  • the difficulty with an arrangement that has a transparent mask body in the vicinity of the front of the face is that working mechanisms must be moved away from the front of the face.
  • a major difficulty with such an arrangement when the filters are moved away from the nose and mouth is that there is a large region of contaminated air or exhaled air that mixes with air that is inducted through the inhale valve resulting in poor quality air with high levels of carbon dioxide, available for inhalation.
  • the present invention solves this problem by creating an “inhale duct” within the filter body, that at one end has the inhale valve which in turn is next to the inhale filters, and at the other end lies adjoining the nose and mouth.
  • the remaining part of the filter body houses the air that has been exhaled and is conducted through the exhale valve to the outside (either directly or on some embodiments, an exhale filter).
  • the functionality can of course be reversed in some embodiments where there is an exhale duct that conducts air out of the mask and the remaining parts of the volume of the mask are used for the inhaled air. Pressure build up caused by each of the two valves determine the flow of air.
  • the inhale valve closes as sooner the pressure wave traverses the inhale duct (a few milliseconds) and reaches it, while on the other hand the exhale valve opens when the pressure wave reaches it after traversing the distance to the valve through the mask body ( a few milliseconds).
  • the exhale valve opens when the pressure wave reaches it after traversing the distance to the valve through the mask body ( a few milliseconds).
  • inhale and exhale valves it is not necessary to have both inhale and exhale valves to be displaced from their nose and mouth area.
  • Some embodiments will simply have the inhale duct with the inhale valve placed away from the face and the exhale valve placed closer to the mouth but possibly below the mouth to avoid obstruction of vision of the face.
  • the masks of this invention are best fabricated with transparent materials to cover the face thereby providing full visibility of facial expressions for better communications.
  • the drawings show half the mask on one side of the face, and in the interest of clarity do not show the sealant architectures around the age of the masks to seal airflow.
  • the shapes of such masks in many embodiments could be different but still benefit from the invention.
  • An exhale filter in some embodiments will have the architecture of a fabric or other bag (filter bag) that inflates during exhalation and empties its contents though the filter material of the bag during the cycle of inhalation and exhalation thereby providing a higher pressure gradient across the exhale valve at all times, improving the time for opening the valve during exhalation, and avoiding a pressure build up outside the exhale valve if a filter with a high required pressure differential is used.
