Title: Improvements relating to selective switching devices for electric circuits
IPC: H01H9/26
Filed: 1928-01-04
Abstract: 306,663. Tyer & Co., Ltd., and Leake, F. W. Jan. 4, 1928. Controllers, interlocking.-In a switch for connecting any one of a number of circuits to the same source of supply, a locking-device such as a sliding bar G, Figs. 1 and 2, prevents movement of the circuit-changing spindle F unless a line-switch spindle A has previously been moved to break the common line-connection. The lineswitch handle C is linked to the bar G, which lies close to a squared end of the spindle F and thus locks it. The act of opening the line switch brings a recess g opposite the squared end and thus frees the spindle F. Springs to produce a quick break may be added to the line switch. In a modification a notched disc moving with the circuit-changing switch is locked by a pin on the fine-switch spindle.

Title: Improvements in and relating to pressure-fired steam generators
IPC: F22B1/24
Filed: 1937-03-12
Abstract: 475,766. Automatic control systems. AKT.-GES. BROWN, BOVERI, & CIE. March 12, 1937, No. 7369. Convention date, March 14, 1936. [Class 38 (iv)] [Also in Groups XXIX and XII] Fluid-pressure.-A steam generator with pressure firing and a blower driven by an exhaust gas turbine is regulated by transmitting the controlling impulse (e.g. change in steam pressure) to an accelerating motor acting on the blower to vary its speed from which varying speed the fuel feed is varied directly or indirectly, thus avoiding a lag in the aircontrol due to inertia of moving parts, as compared with the fuel feed. A blower 6 feeding air to the generator 1 at A is driven by a turbine 4 supplied with exhaust gases from B, and by an accelerating motor 7 which may be electric or may be supplied with live steam through a valve 8. On a drop in the live steam pressure due to increased demand, a piston 10 closes the outlet valve 11 of oil under pressure at U, thereby increasing the pressure under a piston 9 and opening the valve 8 of the accelerating' turbine 7 (or displacing the control resistance of the electric motor) to speed up the blower 6. Thereupon, a tachometer 19 or other suitable means through a predetermined cam 20 (for indirect action) closes an outlet valve 21 of oil under pressure at V, increasing the pressure under a piston 3 and thereby opening the feed-valve 2 of fuel supplied at C. Where relief of the load on turbine 7 by lowering of oil-pressure under piston 9 is insufficient to reduce the air and fuel, the increased steam pressure will still further open oil valve 11 reducing pressure below a piston 23 to open a valve 24 byepassing the gases driving turbine 4 and thus reducing its speed. An abnormal rise in steam pressure opens an oil outlet safetyregulating valve 26 allowing piston 3 to close the fuel valve 2, the air-supply also falling as a consequence. A turbine 12 is shown driven from the generator 1 through steam admission valves 16 controlled by a governor 13 and outlet valve 14 for oil under pressure at W. This oil pressure also acts on a piston 17 moving a normally stationary sleeve 18 of valve 11, so that an increase in load on turbine 12 with reduction of its speed opens admission valves 16 and at the same time closes valve 11 to speed up the blower and open the fuel valve before the pressure in the generator drops.
