Title: Cooling chamber for IC engine afterburner - has second stage of cooling using same cooling tubes as first stage
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1977-03-21
Abstract: The afterburner of an i.c. engine has a cooling section downstream of the burner chamber. Gases enter this section through two perforated plates (1, 2) and impinge on baffle plates which are formed by one side of cooling tubes (4). A perforated ceramic plate (6) is held longitudinally between two such cooling tubes. The gases pass through it and enter a second cooling chamber. They impinge on the far wall of this which has the atmosphere on its other side. The gases are cooled in this second chamber both by the atmosphere on one side of it and by the cooling tubes on the other side. A second stage of cooling is thus obtained with a single set of cooling tubes.

Title: Nuclear reactor cooled by unpressurised molten salt - and secondary steam circuit which can operate at high temp. producing dry steam
Inventor: VOX ANTON J
IPC: G21C15/28
Filed: 1977-08-12
Abstract: A nuclear power plant comprises fuel elements in a reactor vessel with a fused salt as liquid coolant to transmit the heat generated through a heat exchanger into a secondary circuit driving a steam turbine. The salt is melted in a separate vessel at 150-180 degrees C. and atmospheric pressure. It is pumped in through the reactor vessel and circulated by pumps and filters in closed cycle. The reactor vessel is pref. unpressurised and is composed of inner and outer shells of stainless, acid-resistant steel, more specifically a chrome-nickel alloy steel, esp. V2A or V4A. In addition there may be additional cooling lines between the inner and outer shells, either forming part of the main circuit or separate from it; these can act as emergency or additional cooling. By comparison with a comparable two-circuit reactor in the form of a pressurised water reactor, the present cycle operates at atmospheric pressure for the main circuit, thus considerably reducing the risks associated with pressurisation.
