Definitions

  • the conducting bodies are preferably placed serpent inewise or spirally on their means of support.
  • the serpentine can ' ibe formed from a sheet in which parallel cuts are made alterna ingly in one edge or in the edge oppo ⁇ site.
  • the spiral may be circular, square, rectangular or of some other shape.
  • the cross section may remain constant or may differ according to the amount of heat and to the temperature to be reached in the various lengths. Variations in size may be gradual or sudden, con ⁇ tinuous or intermittent, as the particular case and prefer ⁇ ences may dictate.
  • the conducting bodies may receive electric current at their ends or at intermediate points.
  • the heat-emitting surfaces can be placed around enclosed spa ⁇ ces in which temperatures higher than ambient temperatures are required for physical or chemical transformation of ma- terials, so creating static ovens.
  • a hotplate 41 formed by the heat-emitter 42 consisting of a copper lamina of the kind already described. Electricity from the mains reaches the hotplate 41 through the transformer 45 which increases intensity and upgrades heat. From the transformer the wires 46, 47 connect to terminals 48,49. Uniform and direct heat is applied to the pan 43.
  • Mains electricity for the radiator is increased in intensity after passing through the transformer 103.
  • transformed current is sent to the two ends of the conducting aluminium cover 107 which clothes the two sides of the insulating plate 108.
