Abstract: A current-transfer assembly for electric machines, including a shaft (22) with electrically conductive slip elements (13, 14, 16, 18) originating from and coaxially surrounding the shaft, the elements supporting carbon brushes. According to the invention, various electric phases are connected to slip elements that are insulated from one another, by means of current paths that lead to the windings of the electric machine. To guarantee that temperature fluctuations do not adversely affect the current transfer, the slip elements are configured as disc elements that consist of or contain carbon material.

Abstract: A laryngoscope including a handle and a spatula that is detachably connected thereto via a coupling. So that an image can be transmitted free of distortion over an image conductor from the spatula in the handle, spatula and handle are connected via first and second projections. The projections make it possible to twist the spatula in relation to the handle as well as snap-fit them to each other.
