A particle deposition system can have a particle source providing a nanomaterial at a controlled rate and a gas distribution system coupled with the particle source and operable to receive the nanomaterial aerosol. A high pressure chamber can be coupled with the gas distribution system, and a nozzle can be disposed between the high pressure chamber and a low pressure chamber. The nozzle can have a nozzle opening allowing fluidic communication of a nanomaterial aerosol between the high pressure chamber and the low pressure chamber and the opening can have a length exceeding a width.

Systems and methods for suppressing vaporization of a volatile fluid dispensed from a pressure vessel are provided. The system includes an evaporator coupled in thermal communication with a first flow of volatile fluid from the vessel and in fluid communication with a second flow of volatile fluid from the vessel. The evaporator includes at least one channel for channeling the second flow of volatile fluid therethrough. A metering valve is coupled in fluid communication with the channel and between the evaporator and the vessel. In addition, the system includes a compressor coupled in fluid communication with and downstream from the at least one channel. Moreover, the system includes a return line coupled in fluid communication with an outlet of the compressor. The compressor is configured to compress the second flow of volatile fluid and channel the compressed second flow of volatile fluid to the pressure vessel via the return line.

An air passage and two lines of cleaning liquid paths are provided in a nozzle, and the air passage is bifurcated into two lines of distal end portions. Then, a distal end portion of the cleaning liquid path and the distal end portion of the air passage are merged. Thus, if the compressed air is supplied to the air passage, the resulting air flow causes a negative pressure on the downstream side. This enables making a cleaning liquid into the form of a mist and suctioning it, and to mix the cleaning liquid in the form of a mist with the compressed air, whereby it is possible to clean the lens surface and to reduce the amount of the cleaning liquid used.

The invention relates to a modular system for weed control for a rail vehicle. The modular system has a control module including a control unit and a control module. The control unit is configured to generate a first set of control signals for controlling valves and mixers in an herbicide and mixing module configured to mix an herbicide mixture and to generate a second set of control signals for controlling valves of a nozzle assembly. The herbicide and mixing module has a plurality of containers for receiving different herbicides. The nozzle assembly has a first set of nozzles for spraying herbicides, and the control module, the herbicide and mixing module, and the nozzle assembly can each be individually fixed to a carrier element in a reversible manner.

In-wall dispensing modules, such as room freshener modules, can reside in a housing with a cover that can be opened to access an interior space of the module to, inter alia, replace used containers. The housings are configured to reside inside a wall of a room. The front cover can be a planar cover that is flush, slightly recessed or slightly protrudes from the wall. The housings can be a “custom” housing size and/or may be configured to occupy a single gang box or a compartment of a multi-gang junction box. The modules can include an actuator that can cause a canister to emit scented fluid at desired intervals and/or on-demand. The modules can have a User Interface (UI) wireless and/or wired connection to a whole-house “smart” system.

An apparatus for dispensing compounds bearing scent in which one or more scent dispensing units contain each one scent bearing compound and is activated mechanically by an electromechanical activator. A user handled device contains a controller, a memory and a communications device. Resident hardware includes a resident channel for communicating with the user handled device and a controlled driver for controlling the scent dispenser mechanically. A wireless peer to peer communications system carries out the communications between the user device and the resident hardware. The user can input parameter for controlling the dispensing unit through a user device interface. A controller in the resident hardware implements a dispenser activation scheme, mechanically expressed by the activator of the scent dispensing unit.
