Abstract: 418,601. Valves. PARSONS MARINE STEAM TURBINE CO., Ltd., COOK, S. S., and DOUGLAS, L. M., Turbinia Works, Wallsend-on-Tyne. April 29, 1933, No. 12555. [Class 135.] In a power installation in which a main prime mover is aided by an auxiliary prime mover driving through a free-wheel clutch, automatic means are provided for disconnecting the auxiliary prime mover when the main prime mover is reversed. Fig. 1 shows an arrangement comprising main geared turbines A, B, each having a reversing section, and an auxiliary turbine E driving through a freewheel clutch F. The clutch of the turbine E may be disconnected by a servo-motor H which is controlled by a pilot valve 8, the stem 5 of which carries a single-helical gear 4 meshing with a pinion 2 on the shaft of the turbine B. When the main turbines are reversed, the gear 4 moves axially to adjust the pilot valve. The pilot valve controls also servo-motor mechanism J which closes and locks the steam admission valve 7 of the turbine E. The stem 26, Fig. 3, of the valve 7 has an operating piston 27, and its end 30 is adapted to be engaged by a locking bolt 34<a> carried by a spring-pressed piston 34. During normal working, the pressure oil in the pipe 13 forces back the piston 34, thus withdrawing the bolt 34<a>. A port 35<a> and pipe 37 connect with the underside of the piston 27 where oil-pressure is set up to open the valve 7. When the main engines are reversed the pressure in the pipe 13 is lost, the piston 34 is moved by its spring 36, and the space beneath the piston 27 is opened to a leak-away 38. The valve 7 may be closed, or the extent of its opening limited, by a lever 43 actuated by a hand-wheel 46. Fig. 4 shows a modified arrangement for actuating the piston 6 of the servo-motor pilot valve. Its stem 59 is connected to the boss 57 of the helical gear 4 which is adapted to move axially on a fixed stub-shaft 54. Spring- pressed studs 50, which bear upon flats on the shaft, fly outwards under the action of centrifugal force. The gear 4 may mesh with one of the transmission gears. The clutch F may be interlocked with manoeuvring valves, or may be operated by the steam pressure in the ahead or astern turbine systems.

Abstract: 792,871. Control of motors; protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. May 4, 1956 [May 6, 1955], No. 13218/55. Classes 38 (3) and 38 (5). A protective system for a dynamo-electric machine such as a traction motor 1 comprises a relay having coil 5 adapted to be subjected to the voltage-drop across series field winding 3 and Compole winding 2. A switch 4, responsive to the temperature of the motor, closes its contacts when the said temperature exceeds a predetermined value, whereupon the relay-contacts 7 are closed to energize an alarm device 8 if the motor-current is excessive. The alarm is switched-off automatically when the motor-current is first reduced to cause the relay 5 to drop-out, after which the current can be increased to a safe value. When the temperature of the motor falls to a predetermined value, the switch 4 re-opens and the driver regains complete freedom of control. In a modification, the coil 5 is shunted across the switch 4 which has normallyclosed contacts, Fig. 2 (not shown). If the machine is of the A.C. type, a current transformer may be used for detecting the load, the temperature-responsive switch having normallyclosed contacts to ensure that the secondary winding of the transformer is never opencircuited. The relay-coil 5 may be connected across an impedance device in series with the machine, and an electronic relay may replace the electromagnetic relay shown.
