    摘要： An electrical space heating element having a ceramic body which is provided on the side facing away from the space to be heated with an electrically resistive coating. The space heating element provides a high thermal yield while consuming little electrical power and may be used as an element of design for the periphery of a room. The space heating element may be installed in such a way so that no channels are formed which might force air currents to circulate in the room to be heated. The electrically resistive coating is a layer of a carrier impregnated with nonmetallic particles which have a large specific area, are electrically conductive, and do not substantially vary the electrical conductivity at higher temperatures. The carrier in which the nonmetallic particles are embedded has no greater than poor electrical conductivity. The electrically resistive coating is applied in such a way that it has uniform electrical and thermal conductivity.

    摘要： In an electrical surface heating element, there are conductors (10) embedded within a panel (1) of electrically insulating material, which conductors are connected to supply conductors or, respectively, to the heating conductors of the surface heating element, and enter cavities (7) of the panel (1) open to the panel edge (6), within which cavities the electrical connecting points for connecting adjacent panels (1) are located. Each cavity (7) is constricted in direction towards the panel edge (6) and can be closed above by at least one removable cover (15,16), so that the connecting points of the conductors (10) are accessible also after having installed the panels (1).

    摘要： Laminated heater plate assembly is formed from a plurality of layers of glass cloth and/or glass mat and epoxy resin which are laminated together under heat and pressure. One or more thermally conductive heater members are mounted in a cut-out region(s) in a pre-cured or "C" stage laminate top portion of the assembly while a plurality of uncured or "B" stage glass mat and epoxy resin laminations are stacked, assembled under the "C" stage portion and heater portion(s), and bonded to each other into a rigid, warp-free heater plate assembly which can be repeatedly subjected to steam or hot water without damage. Preferably, the resin density after bonding in the region of the edges of the heater portion(s) and the adjacent surrounding edges of the cut-out region(s) is greater than in locations spaced further from the heater portion(s) in order to enhance the sealing of the assembly in the most critical areas thereof. In a preferred embodiment the weight of the assembly is reduced by the use of micro-balloons in some laminations, the absence of epoxy in others, and by the elimination of portions of the interior layers.

    摘要： A snow melting apparatus for melting snow on sidewalks, driveways, and other walkways is provided. The snow melting apparatus comprises a plurality of individual heating cables with the heat cables woven together to form a mesh-like covering mat and the covering mat having a top surface and a bottom surface. An outer perimeter border surrounds the covering mat. A snowfall sensor mechanism is mounted to the covering mat with the snowfall sensor mechanism detecting precipitation and automatically activating the heating cables. The top surface of the covering mat is presented for a person to walk and or stand while the bottom surface of the covering mat is capable of being positioned against the sidewalk, driveway, or other walkway. Upon activation of the heating cables, the temperature of the heating cables increases thereby heating the entire covering mat.
