An ozone disinfecting system includes a water holding tank configured to hold water for use by the ozone disinfecting system. An ozone generator machine is configured to convert the water into an ozone cleaner agent. An ozone holding tank is configured to hold the ozone cleaner agent created by the ozone generator machine. A drain is configured to drain fluid from the ozone holding tank to the water holding tank. A pump is configured to cycle the fluid from the water holding tank to the ozone generator machine and into the ozone holding tank. A controller is configured to control the pump, the ozone generator machine, and the drain. Wherein, the controller controls the pump, the ozone generator machine and the drain to create the ozone cleaner agent from the water and cycle it between the water holding tank and the ozone holding tank at a specified cycle time.

The sequential infiltration synthesis (SIS) and Atomic Layer Deposition (ALD) of metal and/or metal oxides on personal medical equipment (PPE). The deposited metal and/or metal oxides imbues antimicrobial properties to the PPE.

There is described a sterilization apparatus for sterilizing receptacle closures, the apparatus including a conveying device for the receptacle closures along an advancement path comprising a guide track defining and/or delimiting the advancement path and an advancement unit adapted to advance the receptacle closures along the advancement path. The advancement unit comprises an endless track, a plurality of cart assemblies moveably coupled to the endless track and configured to interact with one or more receptacle closures coupled to the guide track, an actuation assembly configured to control advancement of the cart assemblies along the endless track. Each cart assembly comprises a cart moveably coupled to the endless track and at least an engagement element coupled to the respective cart and configured to engage with one or more receptacle closures for advancing the one or more receptacle closures along the advancement path.

A water supply system for aircraft that is mounted on an aircraft to supply water to a plurality of water supply outlets in the aircraft. The water supply system for aircraft includes a tank for storing water, a water supply pipe, and an ultraviolet sterilization device. The water supply pipe extends from the tank, branches and is connected to each of the plurality of water supply outlets, and supplies water from the tank to the plurality of water supply outlets. The ultraviolet sterilization device is provided on the water supply pipe close to at least the water supply outlet for drinking water, includes a light-emitting diode emitting ultraviolet light, and sterilizes water supplied to the water supply outlet by irradiating the water with ultraviolet light from the light-emitting diode.

This present invention relates to a portable fogger disinfectant device which is used to disperse a novel disinfecting and sanitizing solution and related propellant to disinfect a room or other enclosed space. The spray material is stored in a pressure-activated cylinder with a nozzle, a sensor and a timer. In one embodiment, the disinfecting and sanitizing solution is comprised of an ethanol, an alkyl comprised of C14, C12, and C16, water as a base for other ingredients, fragrance oils, ethanolamine, a propellant and an ammonium hydroxide.

An ozone injector device comprising a housing, a corona tube disposed within the housing and configured to generate ozone, a check-valve having a first end removably coupled to the water passageway and a second end configured to receive ozone, the second end having a cavity with a movable float contained therein, an ozone inlet fitting removably coupled to the second end of the check-valve, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube such that ozone entering the water passageway through the ozone inlet must pass through the check valve, and a spring-loaded clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet, the clearing piston being biased upwards, and configured to prevent flow of ozone into the water passageway.

An anti-shadowing virus irradiation and deactivation device comprised of air chambers having multiple ultraviolet “C” light sources, with a selectable recirculation path to harness ozone gas produced, and a system to neutralize said ozone gas upon exit.

A device includes a material and a silver titanium dioxide coating supported by the material. The material may be a face mask adapted to be worn by a user. The coating may be applied via a Silver Titanium Dioxide solution. The solution may also be atomized for inhaling. Silver Titanium Dioxide acts as a photocatalyst at least due to the Titanium Dioxide to degrade organic molecules and microorganisms. The silver acts as a Bacteria stat, Fungus stat, and a Virus stat with or without light exposure. A titanium dioxide solution may be applied to skin. Exposure of the solution imbibed skin to light may be performed to remove or reduce tattoos.
