Abstract: The invention describes a method of treating a halogen lamp (1) comprising a filament (4) supported by legs (3, 3?) in a vitreous bulb (2) enclosing a halogenated hydrocarbon fill gas (G), which method comprises applying heat and/or radiation to the lamp (1)—prior to initial operation of the lamp (1)—from a source (S1, S2) external to the lamp (1), so that the halogenated hydrocarbon fill gas (G) is cracked and carbon is deposited essentially at a specific region (R1, R2) of the lamp (1), whereby the specific region (R1, R2) of the lamp (1) is a region in the lamp (1) other than the legs (3, 3?) of the filament (4) of the lamp (1).

Abstract: A screw-in electrode probe for cardiological application comprises an oblong electrode body (1), a supply line (10) running therein, and an electrode head (3) on the distal end (2). The latter is provided with housing (5), a shaft (6) mounted therein so it is rotatable and axially displaceable, and a corkscrew-like screw-in electrode (4) on the shaft (6). A contact spring in the form of an essentially planar spiral spring (11) is situated between these components, whose leg ends (12, 13) are in sliding contact with the housing (5) or the shaft (6), respectively, while exerting a radially directed spring force (F).
