    摘要: A discharge lamp includes a lamp tube containing a noble gas, two internal electrodes, and a secondary electrode disposed outside and close to the surface of the lamp tube. In one embodiment, studs are disposed on the lamp tube so as to affix the secondary electrode. In an alternate embodiment, a reflector includes an indentation pointing toward the lamp tube and configured as the secondary ignition wire.

    摘要: A dental furnace for heat treatment of dental materials and dental components, particularly for firing these at temperatures over 100.degree. C. comprises an insulated furnace space which can be closed off by a door. The furnace space has a housing which is suspended in an inner housing of metal; the inner housing is supported by a multi-part outer housing, and the door is pivotably fastened on the inner housing. In order to satisfy the requirements of firing at up to 400.degree. C., and to achieve a simple, cost-effective, and light construction, the furnance of the invention has a plastic outer housing, connected by securing elements to the inner housing; the plastic elements have a shell-shaped configuration, so that they define a hollow space surrounding the inner housing, at least adjacent the sidewalls of the outer housing. The hollow space serves as an insulator, minimizing the need for other insulating materials.
