Patent DE-3310911-A1 (DE)
Title: Device for the elastic mounting of machines, preferably a static internal combustion engine
Inventor: HORSTMANN CLAUS
IPC: F16F15/027
Filed: 1983-03-25
Abstract: A device comprising a plurality of spring elements is provided between the supporting frame for the internal combustion engine and the base frame in order to provide elastic mounting of a machine, preferably a static internal combustion engine. Each spring element here has a rubber buffer which interacts with a gas-filled spring acting in parallel with the rubber buffer. This gas-filled spring can be connected via a control valve to a compressed-air source, allowing the spring element to be controlled in accordance with the operating phases of the internal combustion engine. This makes it possible to ensure that only the rubber buffer is operating as a spring element when the internal combustion engine is at a standstill, when it is being started up and when it is being shut down as well as when passing through the critical engine speed range, while the spring function is assumed by the gas-filled spring at the operating speed, a high degree of decoupling between the internal combustion engine and the base frame during the operation of the internal combustion engine thereby being achieved.

Patent DE-3401360-A1 (DE)
Title: Salt mine for supplying energy
Inventor: GOERES HANS DIETER WILHELM
IPC: F02B43/10
Filed: 1984-01-17
Abstract: The salt mine is an energy installation, roughly comprising an electrolysis plant for producing hydrogen and chlorine gas in addition to aqueous sodium hydroxide (by-product), which uses the focal heat, from sunlight, and wind power etc., for thermocouple piles etc., to generate electrolysis current, and further comprising as the the main part, a series of special piston/cylinder installations or ram-in-shaft installations for converting chlorine-hydrogen explosions into a drive for generator shaft(s), excess heat produced as a by-product being recycled to the thermocouple piles. In the cylinders/shafts, each ignition is produced by (protected) ultraviolet lamps. The HCl produced is drawn off and, like the aqueous sodium hydroxide, can be sold to industrial users (economic viability). The cylinders/shafts are surrounded externally with flowing water, which is neutralised with base from time to time. As salt, sun (or geothermal heat) are utilised at the same time, a higher efficiency is achieved than in the case of solar energy only being used in generating electricity. The system cannot be used for mobile motors, but only for secure stationary plants.
Patent DE-3403481-A1 (DE)
Title: Thermal compressor
Inventor: EDER FRANZ X PROF DR ING
IPC: F02G1/043
Filed: 1984-02-01
Abstract: The invention relates to a novel version of a thermal compressor, which comprises a closed cylinder filled with a compressed gas, a displacement piston oscillating therein periodically, as well as heat exchangers for supplying and removing quantities of heat, and a thermal regenerator. In contrast to the conventional arrangement of the regenerator outside the working cylinder, it is accommodated in the interior of the mobile displacement piston and has the working gas flow through it in an axial direction. The predominantly externally disposed heat exchangers having a constant exchange area are replaced by, in each case, two interlocking rotating parts having a high heat conductance, of which the mobile parts are attached to the end faces of the displacement piston, whereas the fixed exchange surfaces form part of the combustion chamber or the cooler. During each working cycle, the working gas is pressed through the narrow gas gaps between the mobile and the fixed exchange surfaces, which results in an extremely effective heat transfer to the regenerator. Both measures are suitable to achieve high thermodynamic efficiency of the machine.
