In an ultrasonic transducer assembly, a conformable ultrasonic transducer has a piezoelectric layer and electrodes able to conform to curved surfaces, and a clamp for pressing the transducer into ultrasonic contact with a curved surface. Conformability is ensured with a thin, porous piezoelectric layer and suitable electrical conductors and insulators. The ultrasonic transducer may operate without further thermal shielding under harsh environments and / or at high temperatures.

The invention relates to a liquid cleaning device that is intended for purifying liquid from pollutants, which liquid cleaning device includes a vessel, having a lower chamber and an upper chamber, which lower chamber is connected to a heating member arranged to heat the liquid in said lower chamber, as well as further including a riser and liquid-distributor member, which riser is arranged to transport heated liquid from said lower chamber up to the upper part of said upper chamber, where the liquid-distributor member is arranged to impart the heated liquid an increased area of exposure to surrounding air, the liquid then, by means of the gravity, running back downward outside the riser and being collected in the lower part of the upper chamber of the vessel, said upper chamber and lower chamber being in at least conditioned communication with each other in order to allow transfer of the liquid from the upper chamber to the lower chamber. According to the invention, the heating member is arranged to be capable of assuming at least two power levels and that a change-over member is arranged to automatically reduce the power level of the heating member.

A reclaiming apparatus includes: a container in which a reclaiming process of an absorption liquid is performed; an absorption liquid supply line for supplying the container with the absorption liquid; a heat exchange device, installed inside the container, for heating a liquid inside the container; a circulation line for extracting the liquid inside the container, circulating the liquid and returning the liquid to the container; and a circulation pump installed in the circulation line.

The invention relates to a liquid cleaning device (1) that is intended for purifying liquid from pollutants, which liquid cleaning device (1) comprises a vessel (2), having a lower chamber (8) and an upper chamber (9), which lower chamber (8) is connected to a heating member (10) arranged to heat the liquid in said lower chamber (8), as well as further comprising a riser (13) and liquid-distributor member (14), which riser (13) is arranged to transport heated liquid from said lower chamber (8) up to the upper part of said upper chamber (9), where the liquid-distributor member (14) is arranged to impart the heated liquid an increased area of exposure to surrounding air, the liquid then, by means of the gravity, running back downward outside the riser (13) and being collected in the lower part of the upper chamber (9) of the vessel (2), said upper chamber (9) and lower chamber (8) being in at least conditioned communication with each other in order to allow transfer of the liquid from the upper chamber (9) to the lower chamber (8).

An evaporator includes a vaporization chamber having a monomer inlet and a vapor outlet. There is a vapor nozzle in the vapor outlet. The evaporator also includes a collar positioned between the vaporization chamber and the vapor nozzle which increases the pressure in the evaporation chamber while the conductance through the nozzle is substantially unchanged.

Disclosed herein is a device comprising an evaporator (100); and a heat exchanger (300); the heat exchanger being in fluid communication with evaporator (100); evaporator comprising an outer casing (102); and an inner casing (110) that is disposed within the outer casing (102); the inner casing (110) contacting a plate (200); wherein the inner casing (110) encloses a first conduit (210) that is operative to introduce a carrier fluid into evaporator (100); and a second conduit (214) that is operative to remove carrier fluid entrained with a precursor; wherein the outer casing (102) is detachably attached to the plate (200); the plate (200) contacting a first precursor conduit (306) that is operative to introduce the precursor into evaporator (100) from the heat exchanger (300); where the heat exchanger (300) is disposed proximate to evaporator (100) at a distance effective to maintain the precursor in evaporator (100) at a substantially constant temperature when the ambient temperature around the heat exchanger (300) and evaporator (100) fluctuates by an amount of up to about ± 35°C.

Provided is a vaporizer in which bumping is suppressed and the pressure fluctuation in a vaporization space is very small in a method that does not use a nebulizer. The vaporizer (1) consists of a container main body (10), a heated porous member (30) installed in the vaporizer (1), and an introduction pipe ( 40) and a gas discharge path (7) for discharging vaporized raw material gas (G) to the outside. The outlet (41) of the introduction pipe (40) is arranged in contact with or close to the porous member (30). When the outlet (41) is arranged close to the porous member (30), the separation distance (H) from the outlet (41) to the porous member (30) does not exceed the distance from the outlet (41) to the The surface tension becomes within the range of the size of the lower end of the liquid raw material (L) that becomes a droplet and hangs down from the outlet (41).
