Abstract: An infrared, room heater system for installation in a wall or on a floor. An electric fan assembly draws room air into a housing, then through three parallel, air transit channels where the air is heated by infrared radiation within and about a heat exchanger assembly, and then back out into the room. One or more ceramic heating elements attached to a first copper plate emit infrared radiation when electrically energized. The first copper plate lies adjacent to, but spaced away from, a second copper plate such that radiation emitted from the heating elements reflects back and forth between the plates. Room air passed between the copper plates is heated by heat radiation concentrated between the plates, thereby achieving both energy and space efficiency.

Abstract: An apparatus for thermally treating semiconductor substrates has a processing space which is defined by first walls substantially parallel to the semiconductor substrate and a second side wall connected to the first walls; a substrate holding device disposed in the processing space which defines a substrate retaining region for a semiconductor substrate in the processing space; and heating elements which are disposed in the processing space between at least one of the first walls and the substrate retaining region. The thermal gradient between the edge of the semiconductor substrate and the center of the semiconductor substrate can be effectively compensated by providing a shutter between the substrate retaining region and the heating elements which limits the radiation emitted in the processing space by the heating elements in the direction of the substrate retaining region.

Abstract: A method for making a transparent electrothermal body includes: a) plating ITO (indium tin oxide) onto a surface of a transparent substrate to form an ITO film, and b) printing a conducting material onto a surface of the ITO film to form two connecting portions each electrically connected to the ITO film, thereby forming a transparent electrothermal body. Thus, the transparent electrothermal body includes a circuit made of ITO material having greater transparency to form a conducting film that allows passage of the electric current, thereby enhancing the transparency of the electrothermal body, and thereby increasing the versatility of the electrothermal body.

Abstract: A cloth heater and method for using the heater are provided. The heater utilizes a horizontally disposed surface, a heated glass panel, and support members. The horizontally disposed surface may comprise the top edge or surface of the heated glass panel, or a surface on a separate rack that is above and vertically inline with the top edge of the heated glass panel. The heated glass panel also has two opposing major surfaces. The support members physically support the heated glass panel and have electrical leads that communicate electrical power to the heated glass panel, thus heating the heated glass panel. When a cloth is placed across the horizontally disposed surface, the horizontally disposed surface supports the cloth, and the cloth makes contact with the two opposing major surfaces of the heated glass panel, thus heating the cloth at both opposing major surfaces.

Abstract: A radiant electric space heater is provided with a halogen light source which provides light to the same general area to which radiant electric energy is transmitted by the heating elements. The halogen light source includes a halogen light bulb located behind a grill that covers a window located at the front of the heater. A translucent lens is mounted on the rear of the grill in front of the halogen bulb.

Abstract: Disclosed herein is a heater comprising a wall-engaging member mountable to a wall, an extendable arm including proximate and distal ends. The proximate end being mounted to the wall-engaging member. The heater also includes a heat projecting heater-head mounted to the distal end of the extendable arm. Wherein the heater-head is reciprocally movable between a first position where the heater-head is in close proximity to the wall-engaging member and a second position where the heater-head is distant from the wall-engaging member.

Abstract: A heater element support frame is pivotally mounted at one edge to a support member attached to a reflector for movement between a first position disposing the frame adjacent to the reflector and a second position in which the frame is spaced from the reflector. Heater element end caps are slidably mounted in slots formed in sidewalls of the frame and mountable in a selectively adjustable position along the slots. Alternately, slots are formed in the reflector and arranged in a dimensional relationship to receive the end cap mounts such that the ends of two adjacent alternating heater elements of two side-by-side arranged columns of heater elements are offset from each other such that the heat generating portion of one heater element overlaps a non-heat generating portion and the end cap of an adjacent heater element.

Abstract: An electric heating assembly adapted to be mounted onto and plugged into a wall-mounted electrical outlet includes a heating unit having a plug member an a back wall, thereof which is directly mateable with a power receptacle of the electrical outlet. The heating assembly also includes a mounting clip for securely coupling the heating unit to the electrical outlet so that the heating unit will not become inadvertently disengaged therefrom. The mounting clip includes a generally rectangular base portion securable to the outlet plate of the electrical outlet with the screw used to mount the outlet plate. The mounting clip also includes a pair of legs which extend away from the base portion and which mate with a pair of holes formed in the back wall of the heating unit above the plug member.

Abstract: A heating unit includes a frame and a substantially flat radiant heating surface supported by the frame. A generally parabolic trough with a reflective inner surface is mounted along one edge of the periphery of the heating surface, and contains an elongate heating element. Further, a reflective flap is hingedly mounted adjacent the trough but remote from the heating surface, disposed so that at least a portion of the radiant energy reflected out of the trough by the reflective inner surface is re-reflected by the flap, depending upon its angulation with respect to the heating surface.
