Title: Oil or gas-fired sectioned-boiler circulating water system - has additional control thermostat for return-water temperature
Inventor: BOLZ GUENTHER
IPC: F24H9/20
Filed: 1973-10-31
Abstract: The sectioned boiler has supply and return connections for a circulation system leading through e.g. radiators, and there are two separate control circuits, one influencing water flow through these, and the other, with a supply thermostat, controlling a fuel valve. The second thermostat has its heat sensor in the lower half of the boiler, in the temperature-influencing area of the return water.

Title: Endless saw for cutting synthetic foams - comprising a steel cable with helically wound flights or barbs
Inventor: EISELT GUNTER
IPC: B23D61/18
Filed: 1974-09-04
Abstract: Moving cutter comprises an elastic core cable of 0.5-2 mm. dia. with a braking strain of 5-30 kp and having a rough surface moving at 30-60 m./s. perpendicularly to a block of synthetic foam being traversed past the moving cutter to obtain a straight or curved profile cut.
