Abstract: 1441826 Metal pouring apparatus BRITISH STEEL CORP 31 Oct 1974 [7 Nov 1973] 21571/73 Heading B3F [Also in Divisions G3 and H4] The rate at which metal is teemed from a vessel is controlled by a slide gate valve 7 in response to any difference between the measured value for the discharge rate and a desired value (set at 15). As shown, the rate is measured by obtaining the rate of change in weight of the vessel (for of ingot moulds 5 or a tundish), detected by a load cell 8 and corrected for variations due to swinging movements by the output of an accelerometer 10. The actual weight and the rate are displayed at 13. The error, obtained at 14 is converted from an electrical to an hydraulic signal at 17 to operate the valve 7. Alternatively, a current may be induced in the metal flow below the valve and detected slightly downstream, or microwave signals may be reflected from the surface of metal in the mould to determine either its height (by echo time) or its rate of rise by Doppler effect. The rate may be varied, e.g. as the mould metal reaches a predetermined level, either manually by control 21 or by programming the reference value.

Abstract: 257,946. Aktiebolaget Vaporackumulator, (Assignees of Warmespeicher Dr. Ruths Ges.). Sept. 5, 1925, [Convention date]. Arrangements; steam regenerative accumulators.-In installations with independently fired boilers of different pressures and overflow valves permitting excess steam from the high pressure boilers to pass to the low pressure main, the low pressure boilers which work with pressure fluctuations are provided with shower, spray or other means for intimately mixing the excess steam with the water either in the steam or water spaces of the boilers so that an increase of pressure occurs only gradually due to condensation in the steam receiving boilers. An installation A working at e.g. 20 atmospheres is connected by an overflow valve V to an installation B working at e.g. 8 to 4 atmospheres. Valves R1, R2 are located in the pipes leading respectively from the steam and to the water spaces of the low pressure boilers. To prevent blowing off of further steam when the maximum pressure has been reached, an accumulator S may be included in the system. In the plant shown in Fig. 2, a medium pressure boiler B and a low pressure boiler C are provided, an overflow valve V2 opening when the maximum pressure in boiler B has been reached. Reducing valves R3 may be connected in parallel with the overflow valves and set so as to open when the pressure in the lower pressure main has fallen to the minimum. Power consumers may replace or be combined with the overflow valves. Boiler feed may be drawn from the accumulator, and higher pressure boilers fed from low pressure boilers. To ensure in any case an absorption of excess steam. boilers B, C, may be worked at rather lower than the predetermined pressures.
