  • Patent number: 7969074
    Abstract: The invention relates to a mercury-free low pressure discharge lamp with a discharge vessel having an ionizable filling. The surface temperature of the discharge vessel, and thus the temperature of the ionizable filling, can be adjusted at least in some sections such that an emitting substance can produce the radiation required for the excitation of the luminescent substance. The temperature of the fluid is preferably adjusted in a temperature control circuit, using a temperature sensor, a pump and a heating device.

  • Patent number: 7701141
    Abstract: The high pressure discharge lamp is fitted with a discharge vessel that has an inside volume with an inside length IL and a maximum inside diameter ID, and that is subdivided into a middle region of constant inside diameter ID and two end regions of variable inside diameter, an electrode projecting into the discharge vessel in the end region in each case. In addition, the discharge vessel has an aspect ratio of 2.5 to 8, preferably 3 to 6, the end region exhibiting a given length LRD in which the inside diameter is reduced to at least 85% of ID.

  • Patent number: 4189106
    Abstract: A delivery arm for depositing wire in a laying reel has an elongated and rigid support member formed generally as a three-dimensional spiral having an upper axially opening inlet end and a lower tangentially opening outlet end. Two generally parallel rows of rollers are mounted on the support member and define a generally spiral path therealong for a rod or wire that moves from the inlet end to the outlet end. Each of the rollers is rotatable about a respective roller axis generally perpendicular to the path at the respective roller and has a generally hyperboloidal outer surface engaging and guiding the wire or rod.
