An improvement to a roadside sprayer fixates spray nozzles on a registration plate. The registration plate may include integral tabs depending on the application. Inclination of the tabs is adjustable to place streams and droplets in a desired swath coverage. With the nozzles rigidly mounted onto the plate, the entire plate is notated. The use of the registration plate in a spray unit creates a uniform nutation among the nozzles, thereby reducing variability in droplet placement, and providing a more predictable spray from the nozzles. In other embodiments, the spray unit is utilized in a spray system adaptable to service vehicles, and may be utilized in conjunction with a vegetation engagement device, such as a cutter to engage multiple zones of a roadway right-of-way. Additionally, an improved spray unit includes an electromagnetic field and an attractor to generate plate motion.

An artificial flame apparatus produces a simulated flame using a plume of mist that is illuminated around, about, and/or through an artificial wick. A mist may be produced by a transducer, such as an ultrasonic transducer, that is in contact with liquid from a liquid reservoir. The rate of mist exiting the housing may be modulated to produce a more realistic looking artificial flame. An airflow device may control, shape, vary, and/or move the mist in the creation of the vapor plume. Airflow channels, inlet and outlet ports, openings (angled and/or straight) to effectively transport air to control movement and/or shape plume characteristics (e.g. height, width, density, shape) to simulate the look and effect of a realistic dancing flame. A light source is configured to illuminate the mist and/or the artificial wick.

An apparatus is provided for nebulising a liquid from a liquid supply through a membrane comprising first and second surfaces and a plurality of apertures extending through the membrane. The apparatus comprises an area for receiving a liquid supply, arranged to deliver a liquid to the first surface of the membrane, a vibrator member, arranged to vibrate the membrane to eject liquid droplets from the front surface of the membrane on vibration; and a mechanical coupling means, arranged to provide a removable mechanical clamping force for clamping the membrane to the vibrator member. Various means for implementing the mechanical coupling are provided, and liquid containers and membranes for use in the device are proposed.

A cartridge for mounting on a main body of an aerosol generating device includes: a liquid storage extending in a longitudinal direction of the cartridge to form an outer wall of the cartridge, the liquid storage including a space accommodating a liquid composition therein; a heater that heats the liquid composition accommodated in the liquid storage to generate an aerosol; and a coupling protrusion including an elastic material, the coupling protrusion protruding from an outer surface of the liquid storage and coupling the main body to the cartridge.
