An apparatus for vaporizing a chemical agent and delivering the chemical agent as a fumigant to an area requiring treatment is disclosed. The vaporizing apparatus includes a heater in fluid communication with a gas stream. A mixer is in fluid communication with a chemical agent stream. The heater heats gas to produce a hot gas stream. The hot gas stream is directed to the mixer whereby the hot gas stream contacts the chemical agent stream, vaporizing at least part of the chemical agent stream. A method of treatment using the apparatus is also disclosed.

A fluid dispersion assembly comprises a diffusion unit disposed in fluid communication with a fluid container, the assembly being powered by a compressed air source. The diffusion unit at least partially defines a diffusion chamber, and includes a diffusion assembly containing an atomizer assembly which, in combination with the diffusion chamber, generates a fluid dispersion from a mixture of compressed air and an operative fluid, for example, fragrant oils, essential oils, odor neutralizers, disinfectants such as triethylene glycol, air sanitizers, etc.

An arrangement introduced into a motorized nebulizer equipped with a pneumatic nozzle for generating cold drops, which allows for the high efficiency of the application through the formation of a droplet spectrum within the range of sizes recommended by the World Health Organization (WHO) for the control of insects, in particular, mosquito vectors of human diseases, in flight, which is a spectrum with a median volumetric diameter (MVD) of less than 30 microns (m).

A space modification apparatus includes a treatment tank configured to generate a gas phase around a rotating center of a rotating flow of a liquid by rotating the liquid, a first electrode of which at least a part is in the treatment tank so as to be in contact with the liquid in the treatment tank, a second electrode in contact with the liquid in the treatment tank, and a power source configured to apply a voltage between the first electrode and the second electrode to generate plasma in the gas phase to generate modification components, the modification components being dissolved and dispersed in the liquid, and a modification liquid being generated and retained in a storage tank. The modification liquid is sprayed or scattered from a nozzle into a treatment target space via a supply pump in the form of mist.

A spraying apparatus is configured such that a liquid stored in a liquid storage tank is pressurized by a liquid supplier and is supplied to a mist nozzle, so that a liquid flow is introduced from an upstream of a gas-liquid mixing section and a vicinity of a wall surface of the gas-liquid mixing section into the gas-liquid mixing section on an outer lid side. A pressurized gas is supplied from a gas supplier from a facing surface, so that a gas flow is introduced into the gas-liquid mixing section and collides with the liquid flow, and a gas-liquid mixed flow is advanced to a spout portion while circulating the wall surface of the gas-liquid mixing section on the outer lid side.

A method of applying heat shield material to form a heat shield layer on a crown surface of a piston of an engine is provided. The method includes the steps of disposing a dispenser that linearly discharges the heat shield material toward the crown surface, and moving an applied position of the heat shield material with respect to the crown surface in a circumferential direction of the crown surface, while discharging the heat shield material from the dispenser toward the crown surface.

A variety of dispensing manifolds which are removable connectable to a single deformable container having a single exit portion are disclosed. The dispensing manifolds of the present disclosure provide a single deformable container having a single exit with one or more outlets from which a fluid can be controllably dispensed. The present disclosure also provides a single force generation mechanism, a deformable container holding a fluid or substance, and dispensing mechanisms all on one machine, i.e., a carrier; a system that may also include a pressurized air source that assists a flow of a fluid; and a system that allows for a continuous flow a substance. The systems of the present disclosure provide a deformable container and a method of dispensing wherein, during dispensing, an actuation member is continuously free of contact with the fluid or substance within the container and the actuation member only contacts the exterior surface of the deformable container.

An apparatus for coating an injection medical device includes an inlet tank fillable with a coating

substance, a delivery nozzle configured to deliver the coating substance to an injection medical device, and a supply assembly interposed between, and in fluid communication with, the inlet tank and the delivery nozzle, the supply assembly being configured to withdraw the coating substance from the inlet tank and to supply it to the delivery nozzle. The supply assembly includes at least one sterilisation filter configured to filter the coating substance withdrawn from the inlet tank. A method of for coating an injection medical device is also disclosed.

A makeup machine includes a multi-nozzle spray head and a plurality of needle valves. The multi-nozzle spray head has a main body and a plurality of nozzles. Each of the nozzles includes an interior chamber and an ejection hole, and the interior chamber is communicated with the ejection hole. The needle valves are disposed in the main body and axially aligned with the ejection holes. The needle valves are configured to be axially movable away from the corresponding ejection holes to open the ejection holes and to be axially movable towards the corresponding ejection holes to close the ejection holes. Further, the needle valves are capable of synchronously or individually moving with respect to the main body.

A volatile composition dispenser and a method of dispensing a volatile composition is provided. The volatile composition dispenser includes a reservoir for containing a volatile composition and a transport member having a first end portion and an opposing second end portion, and an evaporative surface. The first end portion of the transport member is in fluid communication with the reservoir and the second end portion of the transport member is in fluid communication with the evaporative surface. The volatile composition dispenser also includes an air pump in gaseous communication with the reservoir.
