Abstract: In the field of transformation of material there is a device for producing a plasma, a method for ionizing material using the device, uses of the inventive method and production processes using the device. The device includes a resonant chamber, an acoustic chamber provided with an acoustic device and a soliton chamber for receiving the treated material coming from the resonant chamber while simultaneously generating a recycling of outside air. The soliton chamber defines, with a pulsating suction member adjacent to the output of the soliton chamber, a space producing ionized material.

Abstract: A method concentrating energy to produce large velocity, high pressure and/or high temperature conditions, including the steps of forming a resonant cavity inside a container, filing the resonant cavity with a liquid having a compressibility that is smaller than that of water at room temperature; coupling energy into the resonant cavity at a frequency which drives the resonant cavity at or near a resonant mode thereby creating one or more velocity nodes in the resonant cavity; and capturing a quantity of material or mixture of material in the resonant cavity at one of the velocity nodes.

Abstract: A wood burning fireplace in which exterior air is heated during flow through a chimney hood. Recirculated air from the room is drawn in and mixed with the heated fresh air in a zone formed between the chimney hood and a decorative hood casing. A linked damper arrangement is provided with one damper on the chimney pipe to control the fire draught and one on the fresh air inlet so that the amount of fresh air admitted is proportional to the amount of air extracted from the room.
