Abstract: A charge demand controller device for electric vehicles or the like, preferably for installation with an existing residential electrical control panel, connects between a main switch and the electrical control panel made to operate at a maximum amperage value. The device includes a controller unit that constantly monitors an actual total load current at the input line connector from the main switch, and selectively operates a load switch controlling an electric vehicle supply equipment (EVSE) upon the actual total load current being above or below a trip value being a predetermined safety ratio of the maximum amperage value.

Abstract: A steam humidifier provided by the present invention has a tank having a reservoir section and a cover removably and sealingly secured thereto. The tank contains water during a humidifying operation in which the humidifier humidifies an indoor environment. The cover has a heating element mounted thereon and extending therefrom into the reservoir section and a steam outlet assembly mounted thereon and extending therethrough into the tank. The heating element evaporates at least a portion of the water during the humidifying operation into steam output through the steam outlet assembly to humidify the indoor environment.

Abstract: The air diffuser of this assembly has a top collar with a free edge and the damper is of conventional construction, having a central core and a set of radially outwardly extending strut arms. In the central core is mounted a vertical actuating screw for adjusting the air deflector blades of the damper. The outer ends of the strut arms are formed with a stop member resting over the top edge of the diffuser collar and with a system to deform the collar walls so as to lock the strut arms to the collar against axial movement and against rotation. The stops serve to locate the damper in its proper operative position so as to direct the air uniformly over the air diffuser baffles.
