Title: Ballistic fusion warhead with gas charge - has initiating piston heating gas for detonating main charge inside hollow steel cylinder
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: F42B12/20
Filed: 1976-01-15
Abstract: The ballistic fusion warhead is used for shells, bombs and rockets. The armour penetrating or detonating effect is based on the atomic nucleus fusion of an enclosed gas. The process is initiated and maintained by the process for generating high pressure and high temperature in gasses. A small initial quantity (6) of gas is heated by a piston to fusion temperature for igniting a fuse augmenter system (9,11). The latter ignites the main charge. The initial gas quantity (6) is compressed to the fusion temperature of the light atomic nuclei. All chambers are filled with suitable gas and the main gas charge is deuterium, tritium or hydrogen.

Title: Heat pump evaporator - with internal heating of coolant by solar heat and external by warm air
Inventor: GELESIC ANTUN DIPL ING
IPC: F24D11/02
Filed: 1977-11-19
Abstract: An evaporator for a heat pump consists of a heat exchanger with several parallel tubes through which the fluid from the absorbers of a solar heat collector flows in a closed circuit. These tubes are surrounded by concentric tubes for a coolant which is allowed to expand, is heated up and evaporates at the top outlet. These outer tubes are ribbed and are housed in a case through which a fan drives warm ambient air or the hot exhausts from other sources of heat. Air and solar heat can thus never have a detrimental effect on each other; separate thermostats can cut out one of them.
