A heating element for a cooking appliance includes terminals that act as electrically conductive contact points. One or more buses are arranged between the terminals, and connect one or more heating element segments in a zig-zag configuration. The heating element segments are connected in series and are arranged parallel with one another. Each heating element segment includes a plurality of cutouts linked together and having an elliptical shape. The terminals, heating element segments, and buses are a continuous single sheet of conductive material. A method of making the heating element includes forming a pattern into the sheet of conductive material by etching the pattern into the conductive sheet using photolithography.

An electrical heating device with a tubular metal jacket and with at least one electrical heating element, which is arranged electrically isolated from the tubular metal jacket in an interior of the tubular metal jacket. The electrical heating element runs parallel to a tube center axis of the tubular metal jacket and has a wave-like shape such that wave peaks and wave valleys are produced.

A laminate comprising a base material film, a resin layer (1) having a detachable surface, and a heat-generating conductive layer in this order.

The grounded modular heated cover is disclosed with a first pliable outer layer and a second pliable outer layer, wherein the outer layers provide durable protection, an electrical heating element between the first and the second outer layers, the electrical heating element configured to convert electrical energy to heat energy, a heat spreading layer, and a thermal insulation layer positioned above the active electrical heating element. Beneficially, such a device provides radiant heat, weather isolation, temperature insulation, and solar heat absorption efficiently and cost effectively. The modular heated cover quickly and efficiently removes ice, snow, and frost from surfaces, and penetrates soil and other material to thaw the material to a suitable depth. A plurality of modular heated covers can be connected on a single 120 Volt circuit protected by a 20 Amp breaker. The modular heated covers are grounded for safety using the conductive heat spreading layer.

An electric heater to heat a flow of a fluid having a jacket block comprising a plurality of longitudinal bores to allow the through-flow of a gas phase medium. An elongate heating element extends through each of the bores that together with the jacket block define a heating assembly to heat the gas. The heating assembly is positionally stabilised within the electric heater via at least one brace configured to inhibit undesirable independent axial and/or lateral movement of the heating assembly within the electric heater.

A knitted spacer fabric has a first warp-knitted layer having wales running in a production direction and rows of stitches extending in a transverse direction, a second warp-knitted layer also having wales running in a production direction and rows of stitches extending in a transverse direction. Spacer yarns connect the knitted layers, and at least one of the knitted layers are composed of nonconductive yarns and conductive yarns. The conductive yarns are incorporated into the one knitted layer in some areas in a functional region extending in a production direction and resting on the respective knitted layer in a connection region that extends over a plurality of rows of stitches as a float stitch.

A transparent pane having an electrically heatable coating and at least one coating-free zone that can be used, for example, as communication window, is presented. The electrically heatable coating is connected to two collecting electrodes, such that a supply voltage applied to the electrodes generates a heating current that flows via a heating field formed between the collecting electrodes, the heating field containing the coating-free zone whose zone-edge is formed, at least in sections, by the heatable coating. Other implementation details include provision of two electrical supply lines electrically connecting the two collecting electrodes to separate subdivisions of an additional electrode. In one case, the electrical supply lines run, at least in sections, in the heating field, in the coating-free zone, in a coating-free edge strip, in a subregion of the coating outside the heating field, and/or in the zone-edge. Methods for producing the transparent pane are also presented.
