A “MINITOX FAN” mouthpiece with a ventilated air flow for a smoking article comprises a housing, a smoking pipe, said housing being configured from two hollow conical detachable parts for connection to one another and to cylindrical appendices at opposite ends for connection to the smoking pipe and to a hose, respectively; a cylindrical cartridge with a cap, which is disposed inside the housing and has a closed bottom with a lip and through slots across the entire surface of the housing; an insert in the form of a hollow cylinder of smaller diameter for placement inside the cartridge, said insert having a closed bottom, a tightly sealing cap and through slots on the cylindrical surface, at each end of which are appendices, having a diameter that is not greater than the diameter of granules of aluminum oxide and silica gel, for suspended placement of the insert inside the cartridge, wherein the cartridge comprises segments containing a moisture-retaining sorbent and an odor-absorbing sorbent in the form of particles or granules, and the insert contains a detoxifying sorbent; and a fan in the form of a wheel with a shaft.

A portable oxygen concentrator designed for medical use where the sieve beds, adsorbers, are designed to be replaced by a patient. The concentrator is designed so that the beds are at least partially exposed to the outside of the system and can be easily released by a simple user-friendly mechanism. Replacement beds may be installed easily by patients, and all gas seals will function properly after installation.

Lightweight, portable oxygen concentrators that operate rising an ultra rapid, sub one second, adsorption cycle based on advanced molecular sieve materials are disclosed. The amount of sieve material utilized is a fraction of that used in conventional portable devices. This dramatically reduces the volume, weight, and cost of the device. Innovations in valve configuration, moisture control, case and battery design, and replaceable sieve module are described. Patients with breathing disorders and others requiring medical oxygen are provided with a long lasting, low cost alternative to existing portable oxygen supply devices.

Apparatuses, systems, and methods are provided for and in conjunction with n external oil coalescing apparatus for receiving an air flow containing oil; a honeycomb material for coalescing oil contained in the air flow; a first end for receiving the air flow containing oil; and a second for emitting air from the apparatus.

Utilization of nitrogen oxides contained in the ambient air including a system and a method with which the nitrogen oxides can be utilized for the production of liquid or solid chemicals.

Methods and systems are provided for an evaporative emission control system. In one example, a method may include halting a dispensing of fuel to a fuel tank during a refueling event by increasing a backpressure in the fuel tank. The halt to fuel dispensing may be executed based on one or more of an upcoming fuel vapor canister purge event and an estimated fuel vapor canister loading capacity to determine a predicted canister breakthrough. The predicted canister breakthrough may be compared to a threshold to regulate a refueling volume.

Systems and methods for waking a controller from a sleep mode are described. In one example, the controller may be woke in response to an estimated amount of time that it will take for a temperature in an evaporative emissions system to be within a threshold temperature of ambient temperature.

An adsorbent device includes adsorbent fibers laid along or wound around a center tube. In a specific example, the adsorbent fibers are porous solid amine adsorbent fibers. A module for purifying a raw fluid includes one or more adsorbent devices that can be installed in a vessel in series or in parallel. The module can be configured for axial or cross flow operation and can be employed to purify a gas containing a contaminant such as an acid gas. In some implementations, the module is provided with one or more heating elements that can be used to release adsorbed contaminant to regenerate the adsorbent fibers.

A canister that adsorbs and desorbs fuel vapor generated in a fuel tank of a vehicle includes a housing and at least one expansion inhibitor. The housing is in a form of a cylinder configured to be filled with activated carbon. The housing includes a filled portion which is an area in the housing filled with the activated carbon; an unfilled portion which is an area in the housing not filled with the activated carbon; a boundary portion that defines a boundary between the filled portion and the unfilled portion; and a center portion which is situated at the axial center of the filled portion. The at least one expansion inhibitor inhibits an expansion of the boundary portion in an outward direction from being greater than an expansion of the center portion in the outward direction.

Methods and systems are presented for diagnosing a breach of an evaporative emissions system. The methods and systems include repurposing a resonator as a vacuum reservoir to reduce a pressure of an evaporative emissions system so that it may be determined if there is or is not a breach of the evaporative emissions system.
