  • Electric air or gas heater utilizing a plurality or serpentine heating elements
    Patent number: 5134684
    Abstract: An electric air or gas heater includes a plurality of equal diameter elongated linear serpentine resistive wire heating elements circularly arranged in parallel about a common axis and disposed within a cylindrical chamber having separable air or gas entrance and exit sections at its opposite ends. Each heating element is disposed in a close-fitting ceramic or quartz tube. The tubes are supported by discs at the opposite ends of the chamber which block air or gas flow outside the cross-sectional area of the tubes. Each heating element has a ceramic cylinder extending through the center thereof through which a wire for electrically connecting adjacent pairs of heating elements extends.

  • Electric heater with thermistor temperature control
    Patent number: 5111527
    Abstract: A forced gas electric heater has a serpentine heating element in series with a preheat coil. Gas to be heated first flows through the preheat coil before flowing through the serpentine heating element. A thermistor is disposed between two adjacent turns of the preheat coil. The thermistor controls the "on" time of a solid state power control device which is in series with the preheat coil and the serpentine heating element.

  • Arc discharge lamp having ceramic arc tube
    Patent number: 4295075
    Abstract: An arc discharge lamp comprises a ceramic arc tube having an electrode at each end, each electrode being mounted on a support member. A ceramic adapter is sealed to a ceramic cylinder which is sealed to the end of the arc tube. The support member extends through the cylinder into the adapter where it is connected to an externally extending lead-in wire by means of a spiral refractory-metal connector. The connector is flexible enough to withstand the thermal stresses resulting from the normal high operating temperature of the lamp.
