Abstract: A portable warm air humidifier for delivery to a room a steam air mixture of uniform moisture and at a temperature that does not cause sensation of pain. A steam ejector is used to mix the steam from an evaporation chamber with the air entering the humidifier with the advantage, among others, of eliminating the need for motors and blowers. A difference in the water level between a water supply compartment and the evaporation chamber provides a constant pressure in the evaporation chamber which is necessary to drive generated steam through a steam nozzle communicating with the steam ejector. The dimensions of the steam nozzle are determined in relation with the rate of steam generation in accordance with steam velocity to effectively eliminate or minimize the noise normally associated with the passage of steam through a nozzle.

Abstract: A liquid fuel burner for burning liquid fuel in the form of a gaseous mixture with air. The liquid fuel burner has a porous member provided at least with a fuel receiving section for receiving the liquid fuel supplied to the burner and a fuel evaporation section from which the liquid fuel is evaporated. An air supplying device is provided for forcibly supplying air to the fuel evaporation section. The rate of air supply is varied by means of a damper or like means. Heating means are provided for maintaining the fuel evaporation section at a substantially constant temperature. The rate of burning is varied while maintaining the air-fuel ratio of the mixture substantially constant, because the rate of evaporation of the fuel is almost in proportion to the rate of supply of air to the fuel evaporation section. The heating means facilitates the evaporation of the fuel and permits a rapid rise and stabilization of burning after ignition.

Abstract: Ambient water and steam in a predetermined ratio are delivered into the entrance of a venturi chamber in a fluid accelerator. The steam condenses and in so doing elevates the water temperature significantly. The heated water passes through a venturi throat and then has its pressure elevated considerably above the pressure of the incoming steam prior to discharging from the accelerator into valved piping leading to cleaning spray headers on opposite sides of the moving metal strip. High pressure, high temperature water cleaning sprays are directed through header nozzles onto the strip to thoroughly clean its entire surfaces. Venturi vacuum is utilized whenever desired to draw a cleaning additive into the system where such additive is entrained in the water stream. Simplicity and economy are achieved in a highly efficient cleaning system.

Abstract: Liquid fuel is distributed in a fluidized bed of refractory particles through the gas constriction plate of a fluidized bed incinerator. The fuel is supplied from a distribution system of circulation pipes situated well below the constriction plate and passed to the fluidized bed through risers by means of a small amount of driving agent, preferably steam, of high pressure supplied from a separate distribution system independently of the primary combustion air and the fluidizing gas. The driving agent and the fuel are passed into the risers through nozzles at the lower end of the risers.

Abstract: A process and apparatus for the production of heat, equivalent in clarity and cleanliness to that of propane, butane or natural gas, but at a lower cost and without the problems or dangers of storage nor risks of fire or explosion during handling, by means of the instantaneous combustion of diafanous liquid petroleum, diesel or other similar combustible fuels mixed with compressed air in an environment which is neither contaminated nor degraded. Thus, it is possible to regulate the flow and simultaneously divide each volume of combustible liquid into particles so small that they distribute and integrate themslves homogenously in a volume of air proportionally adequate for proper combustion.
