A heating element includes a two flexible plastics layers connected in overlying relationship with first and second conductors each running along the element between the layers the side edges with a row of printed conductive strips at right angles to the conductors. A grounding layer comprising a sheet of foil laminated to a carrier is laminated to the heating element. A reinforcing layer in the form of a bitumen anti-fracture membrane is applied on one surface and a reinforcing layer of a fiber reinforced material is applied on the opposite surface for engagement into a tile adhesive layer. First and second strips of an electrically insulating material are applied over the first and second conductors to define slots allowing insertion into the slots of respective clamp type terminals.

A liquid heater (101) includes at least a pair of electrodes (103, 109) each of which having an electrically conducting surface (105, 111) and being spaced apart from each other. The liquid heater (101) also includes a first heating passage (107) defined, at least in part, by the electrically conducting surfaces (105, 111) of the electrodes (103, 109). Electrical power to the liquid heater (101) is provided by an electrical power supplier (17) configured to draw an alternating electrical current having a frequency less than or substantially equal to 60 Hz and supply an alternating electrical voltage having a frequency substantially equal to or higher than 50Hz across the electrodes (103, 109). The electrodes (103, 109) are arranged to make electrical contacts with liquid received into the heating passage (107). The liquid in the heating passage (107) generates heat when an electric current flows through the liquid and between the electrodes (103, 109).

摘要:
A purpose of the invention is a sheathed glow plug having a center electrode composed by coaxially welding a leading end axial shaft and a rear end axial shaft, wherein an eccentricity of the center electrode is made small and a burr generated in a connecting portion is suppressed. Since a connecting end (g) of one axial shaft 6 of a center electrode 4 is made smaller in its diameter than a connecting end (f) of the other axial shaft 5, a butting face between the connecting ends becomes small in its area depending on a diameter of the small diameter side connecting end. Therefore, even if a connecting end face has an error of right angle degree with respect to an axis or is a rough face, it follows that its influence can be suppressed because a diameter of the butting face is small, and a resistance welding can be stably performed. Further, even if a burr is generated in a periphery edge of the connecting face by the resistance welding, a generation amount of the burr becomes small because an area of the butting face is small. And, so long as the burr does not protrude than a main diameter of the maximum diameter side axial shaft, it becomes an allowable range, so that a burr removal can be omitted or a simple burr removal work suffices.
