Abstract: A cooling system for the cylinder head, the inlet manifold and/or the bearings of a turbo-compressor of a combustion engine with a liquid cooling circuit with a radiator, a thermostat and an electric fan as well as a circuit for the cooling of said cylinder head, the inlet manifold wherein the cylinder head and/or the inlet manifold and/or the bearings of a turbo-compressor to be cooled are incorporated in a cirucit (11) which is connected in series or parallel to the part of the engine liquid cooling circuit (6) between the cylinder head of the engine block (1) and the radiator (7).

Abstract: The method provides an X-ray tube rotary anode by increasing the thickness of a thin, highly deformed anode disc to the desired value by deposition of a layer, consisting mainly of molybdenum, by means of thermal spraying. The method provides an X-ray rotary anode which has the attractive properties of a highly deformed anode disc and which also has a large diameter which cannot be obtained by means of the high-speed deformation impact process due to the maximum applicable thickness-diameter ratio.

Abstract: A vertical-flow air diffuser plenum assembly wherein a generally rectangular hood is formed of a single piece of sheet material in a generally pyramidal rectangular shape and a HEPA filter is mounted beneath the hood in a filter housing in airtight relationship with the hood. The hood has a plurality of smooth continuous horizontal ridges extending 360.degree. around the hood between the apex of the hood and a bottom opening thereof. The ridges are spaced between the apex and the bottom of the hood so as to deflect air flowing along the hood inside surface downwardly through the filter medium in a substantially uniform flow pattern thereacross. The ridges are joined by sloping wall portions and have smoothly rounded corners free from creases or breaks in the surface.
