Abstract: A method of providing an efficiently running internal combustion engine including the steps of operating an engine at a constant rpm while increasing the torque load on the engine, measuring the torque value at predetermined intervals of the torque load to obtain a brake mean effective pressure for each of the intervals, and measuring the fuel consumption at the predetermined intervals. The common log of the brake mean effective pressure is plotted against the common log of the fuel consumption for each interval to obtain a straight line curve (10) which extends linearly with a constant first slope to a D-point coordinate (16) after which it continues at a different second slope. A straight line extension (20) is plotted having the first slope and extending upwardly from the D-point coordinate (16).

Abstract: A heat recovery device for boilers with a blower-type burner. A heat exchanger is located in the stack gas stream and through which is passed a medium to be heated and comprises a pot-shaped vessel (2) which can be inserted into the stack gas duct and is closed on all sides. A stack gas inlet (4) leads into the upper zone of the vessel (2) and at least one stack gas outlet (6, or 30 or 31) leads out of the upper zone of the vessel (2) at a distance from the inlet. A substantially vertical partition wall (7; 21) is located in the vessel (2) and extends downwards from the cover (8) of the vessel (2) and ends at a distance from the bottom (9) of the vessel to interrupt the direct stack gas path from the inlet (4) to the outlet (6). Thus, a siphon-type stack gas path is formed with an inlet chamber (10; 26) and an outlet chamber (11; 27). A draft-interruption damper (15; 32) is fitted in the outer vessel wall in the zone of the outlet chamber (11; 27).

The gas-contaminated powdered metal is passed through a vacuum chamber (12, 112) having a gas outlet (14, 114) connected to a vacuum pump (119) which evacuates the chamber (12, 112). The vacuum chamber (12, 112) has first (20, 120) and second (22, 122) ends with a flow passage at each end for directing the flow of the particulate material into and out of the chamber (12, 112).
