Abstract: 105,248. Blackmore, R., and Baumann, K. March 9, 1916. Feed-water, heating.-In a condensing steampower plant, the whole of the exhaust from one or more of the engines or turbines is condensed at suitable intervals during the normal running of the plant, by feed-water, either in the main condenser or in an auxiliary condenser, the flow of circulating water through the condenser being cut off. The cold-feed tank 12, Fig. 1, and the hotwell 15 are in valve-controlled communication with the pipes 5, 7, through which water is circulated through the condenser 2 from the culvert 3 to the culvert 4. A pump 10 delivers the condensed steam to the feed-tank. An auxiliary condenser 18, Fig. 2, may be provided for use exclusively as a feed-heater. Water is not circulated through the main condenser 2 when the auxiliary condenser is in use. The main condenser may be partitioned, one or more parts serving as an auxiliary for use in the manner described above. The condensers may be of the direct-contact type, and the feed-water may be passed through a condenser several times. The apparatus may be provided with two hot-wells, the pipe connexions and valves being so arranged that water may be withdrawn from one of the wells for supply to the boiler while the other well is being filled with condensed steam, and vice versa. In a further modification, the flow and return pipes for the feed-water are connected to the same tank, into which the condensed steam is discharged.

[Also in Division F4] In a method of casting metals a melting chamber of a refractory material in the form of a bell 27 is located immediately above the top of a mould M, the mould surface forming the floor of the melting chamber which is provided with a port 9 for the discharge of molten metal into the mould cavity. The port 9 is closed by a metal plug, which may be formed by the base of the slug 43 of the metal charge itself. Induction heating coil 37 is provided around the outside of the melting chamber bell 27 and is adapted, without movement of the coil to melt the slug 43 progressively downwardly so that all except the thin bottom layer is melted, ensuring the molten metal has reached its casting temperature whereupon the plug ruptures and the whole molten charge passes through the port 9 into the mould cavities. Additional means for inducing the molten metal to discharge into the mould cavities may be provided by introducing gas through an inlet 41 in the melting chamber at a higher pressure than in the mould cavities. In other embodiments, a fusible disc may be located between an outlet in the melting chamber and the entrance to the mould cavity, which fuses when the requisite casting temperature is reached. Alternative forms of melting chambers are described which do not form part of the mould. Further, a continuous charge of metal may be fed to the melting chamber by means of rollers whereby the feed rate is related to the required quantity of metal for each casting operation.
