A method and apparatus for utilizing the waste heat energy of an internal combustion engine in which a turbine is driven by the exhaust gases from the engine and drives an electrical generator. In order to permit a direct coupling between the turbine and the generator and to utilize completely the electrical energy recoverable from the waste heat energy, the generator is a synchronous machine with a non-wound rotor, the generator being connected via an electrical converter to an electric motor which is drivingly coupled to the internal combustion engine to relieve the load therein.

A cooling installation for reducing the oil temperature of oil-lubricated damping bearings, in which a cooling element is employed with one portion thereof in heat-conductive connection with a bearing housing portion, and another portion thereof immersed in the lubricating oil. The cooling element, which is preferably formed of metal wire or strips, may have the end thereof which is immersed in the oil contoured so as to increase its surface contact therewith and to thereby enhance the transfer of heat from the oil to the bearing housing.

Apparatus for photoelectric measurements of a parameter of a movable part such as the rotary speed thereof wherein the part is provided with constrast marks thereon and the light source and the light receiver of the apparatus are not separated by the movable part. The light source and the light receiver are commonly housed in a scanner unit arranged at one end face of a light conductive member, the other end face being positioned proximate to the contrast marks on the movable part such that the light conductive member forms a light beam path for directing light from the light source onto the movable part and for directing reflected light from the movable part to the light receiver. For measurements required within a chamber, the light conductive member extends through a passage in the casing of the chamber which passage may be arranged radially or axially of the chamber and is secured within the passage, which may effect a vacuum-tight seal for vacuum-tight integrity of the chamber, such that the end face carrying the scanner unit is positioned outside of the chamber while the other end face is positioned within the chamber.
