摘要： Presented is an electrically charged heating element configured as a twin reversed spiral or other flat shape for high power density during cross current fluid flow. In one embodiment the element material is wound clockwise in a spiral inwardly to a point and then wound counterclockwise in a spiral outwardly from that point on the same plane as the clockwise winding, and between the clockwise windings, to a point past the beginning of the outer clockwise winding. Hot fluid generators employing such elements singly or in multiple stacked configurations are presented as well.

摘要： A sterilizing apparatus (10, 80) includes an enclosure (18, 84) defining an interior chamber (20, 86) and a door (22) for accessing the interior chamber (20, 86). A fluid source (42, 88) communicates with the chamber (20, 86) to supply a working fluid thereto. A heater (64, 102) heats the fluid in the chamber (20, 86) and a pump (62, 82) moves the fluid in the chamber (20, 86) by the heater (64, 102). A valve (50, 150) communicates with the chamber (20, 86) and with the exterior of the chamber (20, 86) and is configured to vent the fluid in the chamber (20, 86) to the exterior at a pressure of approximately one atmosphere. Such provides superheating and concentrating of the working fluid in the chamber (20, 86). A method of sterilization includes introducing a working fluid into an interior chamber (20, 86) and circulating the fluid through at least one recirculation loop (54, 96) having a heater (64, 102) for heating the fluid to an operational temperature suitable for killing microorganisms. The method further provides venting of the fluid from the chamber (20, 86) so as to maintain the pressure at approximately one atmosphere. The method further provides for killing of very high temperature resistant microorganisms.

摘要： An apparatus and method for the instant generation of superheated steam at normal atmospheric pressure are presented. Such an apparatus includes a water source, a means to convert the water to a mist or atomized droplets and a means to superheat the mist for application onto surfaces and objects. The apparatus and method are based upon the unique properties and behavior of misted water when it comes into contact with a heated surface, such behavior and properties resulting in the efficient and expansive release of energy and superheated steam. Such an apparatus can produce this steam at one atmosphere without the need of a boiler or other required high pressure fixtures or piping.

摘要： A compact steaming device, which may be handheld, and method for the generation at one atmosphere and projection of superheated steam over objects and surfaces for the elimination and control of unwanted microorganisms and pests including, but not limited to bedbugs, fleas, ants, lice and mites. A preferred embodiment of such a compact device comprises a vessel, a base, heating coils, a superheated steam generator and an external power supply for the initial boiling of a liquid to vapor and for subsequent heating of the vapor to superheated temperatures. The device and method allow for the generation of steam or gas and subsequent superheating to be accomplished safely at one atmosphere. The preferred embodiment allows for the free flow of the gas through and out of the compact device safely and effectively relieving any resulting pressure. A multi-watt embodiment is also envisioned which may be handheld or stationary.
