Patent DE-3242658-A1 (DE)
Title: Thermo-mechanical energy converter
Inventor: EDER FRANZ X PROF DR ING
IPC: F02G1/043
Filed: 1982-11-18
Abstract: The invention presents a continuous thermodynamic process which occurs between two different temperature levels and in which the heat power fed at the higher temperature to the working medium which is in the form of gas or vapour is converted into an equivalent amount of pressure energy minus the cooling power. This object is achieved with the aid of two identical working cylinders each with a displacement piston, which pistons can be moved backwards and forwards in a sinusoidal shape phase-shifted through 180 DEG . The heating energy of a fluid or gaseous fuel is fed at a high temperature to the cylinder heads via heat exchangers of the same kind in a common combustion chamber; the processing heat at ambient temperature is conducted away via identical heat exchangers which are connected to the colder working volumes of the cylinders. The heat exchangers for the higher and lower temperature level are connected to one another separately for each cylinder by means of pipelets which are connected in parallel by means of one train and are in good thermal contact and form a common countercurrent heat exchanger. Each of the colder working spaces of the cylinder is connected to two pressurized gas buffers via two non-return valves with opposing transmitting direction, in which buffers the working medium is stored at different pressures. If the two pressure accumulators are connected via a rotating or oscillating expansion motor, mechanical work is produced. A particularly compact...

Title: Modular construction system for producing and extending as desired useful floating areas for human settlement and also technical exploitation of fresh-water and salt-water surfaces
Inventor: GRITZO GUENTER DIPL ING
IPC: B63B35/44
Filed: 1984-02-09
Abstract: Modular construction system for producing and extending as desired useful floating areas for human settlement and technical exploitation of water surfaces. The self-sufficient settlement requires a buoyancy system which is simple to manipulate, can be coupled together and is formed by cylindrical hollow bodies placed in an upright position. Their end faces each have six bores which serve to couple the hollow bodies via connecting pieces with three hollow pins each which can be expanded by collar studs. A perpendicular supporting bar serving to absorb the applied loads can be passed through centre bores in these connecting pieces. The hollow bodies are used as containers via a tight lid up to one-third of the buoyancy. The floating area from these hollow bodies, which is partly pierced in a honeycombed manner, can be held in position or returned by computer control via energy collectors of various construction and various decentralized drive systems. The honeycomb structure enables water-dependent animals and plants to be bred and cultivated in wire-mesh containers. Self-sufficient operation is possible from a minimum area of one square kilometre according to the drawing. <IMAGE>
