Abstract: An electric radiant heater is constructed with a pot detection system for switching on one or more heating areas. The pot detection system operates inductively according to the resonant circuit detuning principle. The sensor consists of a single-turn loop made from thick wire and which in the vicinity of the heating areas is positioned above the latter and just below a glass ceramic plate. In the case of a two-circuit heater, the sensor loop is shaped with clearly defined circumferential areas in said heating areas, so that the signal has a stepped transition between these areas and consequently a pot size detection in adaptation to the heating areas is possible.

Abstract: Connecting conductors located within at least one heating field for heating conductors are configured so that they do not luminate in operation and are not bowed or shifted out of place by thermal loading. For this purpose the conductor is corrugated and also securely anchored at regular center-spacings, it having with respect to the heating resistor greater resistance cross-sections. This achieves for a very simple construction an optically advantageous glow pattern of the heater in every operating mode.

Abstract: The invention is an improved boiler for generating vapor at low pressure from liquid in reservoirs that are not pressurized. Liquid from a reservoir is fed through a supply wick by capillary action to a boiler wick in which the liquid is heated and boiled to a vapor. The heat for vaporization is transmitted by a porous hot seat which sits atop and is in contact with the boiler wick. The boiler wick and hot seat are contained within an insulating cylindrical shroud, which forms a tight seal with the edges of the boiler wick. If the liquid to be vaporized is a fuel for a burner, then combustion heat can be used to supply the heat to the boiler. A resistive heat source can also be used to heat the hot seat and boiler wick.

Abstract: A busbar supplies current to an electrically resistant area heating device, such as an array of fine closely-spaced wires, which extends over a window, e.g. a laminated vehicle windscreen. The busbar is arranged to turn a corner, e.g. a corner of the window, by providing a separate corner piece of busbar strip which is electrically connected to adjacent lengths of straight busbar strip. This facilitates concealment of the busbar, as is desirable for vehicle windscreens, especially when the corner piece is shaped to suit the corner of the window. Electrical connection of the corner piece to the adjacent lengths of busbar strip is achieved by use of a solder of low melting point, which melts on autoclaving of the window.
