(A com- munication from Sulzer Fr&res, Society Anonyme, of Winter- thur, Switzerland.)—Relates to internal combustion, engines employing heavy or viscous oil as fuel. From an internal combustion engine a the exhaust gases are led through a pipe b. The fuel valve c has the driving fuel supplied to it by a pump d. The fuel passes from the storage or supply tank e into the circulation pipe /, in which a large quantity of fuel is maintained in circulation by means of a/separate pump g. To the pipe f is connected a pipe h, the end of which is open to the air, and also a heating coil i, which is heated by the exhaust through the pipe b from the engine. A portion of the fuel passes through a pipe m to the fuel pump d, and thence through a small pipe to the valve c and engine cylinder, whilst the excess oil returns to the circu-' dating pipe /, in which pipe is provided a throttle n. The operation of the device is as follows For starting the engine, assuming that the driving fuel, is too viscous in its cold state, and therefore unsuitable for starting, a separate fuel of a thinner and more fluid nature is supplied from. a tank o. This fuel is supplied to the pipe and passes 9 through the heating coil i and pump g. Brom the latter a portion of this fuel is delivered by the pump to fuel valve c, whilst the remainder returns past the throttle n into the pipe /, and therefore into the circulation. After running for1 a certain time the pipe f, as well as the pump g, will become heated to such an extent that a free flow of the viscous fuel from the tank e is ensured. At this moment the supply of lighter fuel is stopped, and the circulation pipe f is connected to the tank e, when the engine begins to run directly on the heavier fuel. The -circulation may also be automatic, as, for instance, by. thermosiphon action, the flow of the fuel being maintained by the heating coil i. The pump g need not be positively connected to the engine, but may be driven independently. Thus a separate electric or hand-driven pump g1 could be used. In such a case, it would be advisable to insert another separate auxiliary heating device p, main- tained in operation until the heating can be effected by the exhaust gases. The auxiliary heater p is by way of example assumed to be an electric one. Starting with a separate thin fluid;: fuel may then be avoided. The coiled pipe shown in the oil tank e is an auxiliary heating, device, which may be used for warming the oil in that tank. (Four claims.) NEW PATENTS CONNECTED WITH THE COAL AND IRON TRADES.

Lesher,- of the Geological. Survey, Depart- ment of the Interior, as slightly more than 509,000,000 net tons, an increase, compared with 1915 of more than 66,500,000 tons, or 18 per ,cent., and greater by 31,000,000 tons than the record of 1913. , Data furnished by the Anthra- cite Bureau of Information indicate that the production of Pennsylvania anthracite was 88,312,000 net tons, about 600,000 tons less than in 1915. The total output of coal in the/United States is thus estimated at 597,500.,000 net tons, and the official figures when compiled may show 600,000,000 tons, compared with 570,000,000 tons in 1913. The con- sumption of coal bv the railroads in 1916 is estimated to have been 17,500,000 tons greater than in 1915, the use of coal in ‘ the manufacture of coke was greater by 20,500,000 tons, exports increased about 7,000,000 net. tons, the coal mines used 500,000 tons more for steam and heat, and the increase in consumption, mainly by the manufacturing indus- tries, was 21,000,000 tons.
