  • Patent number: 11073247
    Abstract: The present invention provides a system configured to contain and redirect any explosion caused by the combustible gas as a safety precaution. This is accomplished through a cover, a floor plate, and one or a plurality of tanks adapted to retain high pressure combustible gas. The cover and floor plate will create an extremely rigid and temperature-resistant enclosure, while the tanks are positioned inside said enclosure. These components work in conjunction to provide a lightweight and compact system configured to contain an explosion, and alternatively, to redirect the explosion and resultant shrapnel downward and through the floor plate if the explosion cannot be contained.

  • Patent number: 10894262
    Abstract: An electrostatic sprayer system for dispensing and dispersing a liquid containing a spray compound includes a spray cloud dispersal feature that reduces the time that a residual spray cloud containing droplets including the spray compound remains suspended after spraying. A method of dispersing the residual spray cloud is implemented by a control system that causes a flow control system to deliver a non-active gas or liquid in conjunction with stopping delivery of the liquid containing the spray agent and charged with the same polarity, so that a charged cloud of the non-active gas or liquid, which may be air, displaces the suspended active fluid particles. The non-active gas or liquid may be dispensed for a predetermined time interval as determined by the control system, or the operator may control the time interval during which that the non-active fluid is dispensed.

The electrostatic atomizing device (M4) includes a plate-like inclined surface electrode (101) and a plate-like counter electrode (102) parallel to the surface electrode (101). A solution is diffused by diffusers (108) onto an upper end of the surface electrode (101). The solution flows down along a front surface of the surface electrode (101) while being spread in a thin film form, and is atomized by an electric field between the surface electrode (101) and the counter electrode (102).

  • Patent number: 8992830
    Abstract: Provided are methods for decontamination of compartments, such as aircraft compartments and other types of compartments, and systems for implementing these methods. In some embodiments, a method involves detecting presence of one or more contaminants in a compartment. This information is used to select various decontamination conditions. In some embodiments, additional information, such as the type of the compartment (e.g., an aircraft compartment), temperature, and humidity, may be also considered while selecting the decontamination conditions. The decontamination conditions include identification of one or more decontaminating agents to be dispensed in the compartment, temperature profile of the air to be flown into the compartment, and timing of the decontaminant dispensing and air flowing operations. These conditions are selected to increase efficacy of the selected decontaminating agents with respect to the one or more detected contaminants and reduce impact on the aircraft compartment.

  • Publication number: 20150059684
    Abstract: Methods, systems, and devices are disclosed for injecting a fuel using Lorentz forces. In one aspect, a method to inject a fuel includes distributing a fuel between electrodes configured at a port of a chamber, generating an ion current of ionized fuel particles by applying an electric field between the electrodes to ionize at least some of the fuel, and producing a Lorentz force to accelerate the ionized fuel particles into the chamber. In some implementations of the method, the accelerated ionized fuel particles into the chamber initiate a combustion process with oxidant compounds present in the chamber. In some implementations, the method further comprises applying an electric potential on an antenna electrode interfaced at the port to induce a corona discharge into the chamber, in which the corona discharge ignites the ionized fuel particles within the chamber.

    Abstract: A particle generation apparatus and a particle generation method each employ: (1) a nozzle from which exits a liquid micro-jet stream; and (2) a ground electrode separated from the nozzle, where both the nozzle and the ground plane are DC voltage biased when operating the nozzle. Each of the particle generating apparatus and the particle generating method also employ a pair of AC electrodes interposed between the nozzle and the ground electrode and perpendicular to the liquid micro-jet stream. When a liquid supply is supplied to the nozzle, a DC voltage bias is supplied to the nozzle and the ground electrode, and an AC voltage bias and AC frequency bias is applied to the pair of AC electrodes a liquid particle spray is generated by the apparatus and the method. With additional parametric adjustment, the liquid particle spray may be monodisperse and bifurcated.

  • Publication number: 20140217196
    Abstract: An apparatus for chemical separations includes a microfluidic substrate having an outlet aperture for outputting an eluent of a sample. An emitter assembly includes having a deformable end portion, an inlet near the deformable end portion to receive the sample eluent from the microfluidic substrate, and an electrically conductive outlet portion to emit a spray of the sample eluent. A force-applying unit applies a force to the emitter assembly that urges the deformable end portion into contact with the microfluidic substrate. The deformable end portion is more elastic than the microfluidic substrate so that the contact between the microfluidic substrate and the deformable end portion produces a substantially fluid-tight seal between the outlet aperture of the microfluidic substrate and the inlet of the emitter assembly.
