Definitions

  • a heating element is according to the invention, inserted in a glass tube having at least one-U-bend therein.
  • Glass similarly to any electrical insulator, is a poor thermal conductor, but allows radiating heat to pass through. Consequently even when its outer wall is at a comparatively high temperature the inner wall of the glass tube is still far below its melting point.
  • Figure l is a view ofai heating element, partly in section.
  • Figure 2 is a cross-section on a larger scale through a round curling tong arm with a heating element as shown in Figure 1 inserted therein.
  • Figure 3 is a cross-section on a larger scale through a crescent-shaped. curling tong arm with a heating element asshown in Figure 1 inserted therein.
  • Figure 4 is aview of the second form of heating element and Figure 5 is a cross-section on a large scale through a double curved heating tong arm with a resistanceas shown in Figure 4 inserted therein.
  • an electrical heating wire 2 is inserted in a U- shaped tube 1 of ordinary glass.
  • the two ends of the arm of the glass tube are sealed by a common glass seal 3 in which thetwo leads 4 to the heating wire 2 are fused.

  • the helically wound heating wire 2 is first inserted,
  • the glass tube may also be bent into a multiple U.
  • a sinuous glass tube 11 is shown in Fig. 4. Instead of cementing the glass tube in its sheath, it can also be cast in with a substance having high thermal con ductivity.
  • the glass tube 11 of difiicultly fusible glass is cast-in with aluminum 12 and the casting is inserted in a double curved hollow curling-tong arm13: Aluminum is a good conductor of heat and can easily be cast in any desired shape.
