Abstract: The inventive device for aromatizing a gas medium comprises a chamber provided with a flow booster for mixing the gas medium with aromatic fumes. Said fumes are delivered to the chamber by a dispenser which is embodied in the form of a reservoir containing a liquid aromatic substance. The dispenser is provided with a system of nozzles for supplying the aromatic substances to the mixing chamber. The supply of the substance is carried out by producing pressure pulses inside the chamber. Said pulses occur as a result of a pulse operation of actuating elements which are arranged in the chamber and embodied in the form of thermistors, stricting elements and controlled commutator. Said actuating elements are controlled by a field programmed logic array which is also controlled by a panel or a computer and programmed in relation to a value, duration and repetition rate of voltage pulses coming to actuating elements. The diameters of the nozzles range from 10 to 70 ?m, the distance therebetween being less than 50 ?m.

Abstract: The present invention is related to devices for evaporating volatile substances in a closed environment, without the use of electric power, heating elements or absorption wicks, for the purpose of simplifying and maximally reducing the cost of the device, but at the same time maintaining its efficacy and also allowing the user to be able to adjust at will the degree of evaporation of said product. For that purpose, the evaporator device uses a vapor permeable membrane as the element responsible for causing the evaporation of the product to be evaporated. The device is especially intended to be used with the cooperation of an air current with a suitable temperature enhancing the evaporation and diffusion of the volatile substance, such as the ventilation air outlet of a vehicle, for example. The volatile substance consists in an air-freshening product, insecticide or the like. The invention is also related to a method for the evaporation of volatile substances through a membrane.

Abstract: Particulates are removed from a gas stream by contact with a liquid. The gas stream is conveyed through an inlet channel, towards a liquid reservoir which is located below a perforated sheet. Gas flowing through holes in the sheet creates a pressure drop between the inlet channel and an outlet area above the sheet. This pressure drop draws liquid up from the reservoir, through a relatively narrow liquid transfer channel, so that the liquid covers the sheet. Gas flowing through holes in the sheet therefore encounters a layer of liquid located immediately above the sheet. Particulates in the gas are captured by the liquid in this layer. The device requires no pump for moving the liquid through the system, the liquid being transferred solely as a result of the pressure drop induced by the flow of gas.
