Patent GB-947690-A (GB)
Title: Turbine control
IPC: F01D9/04
Filed: 1961-03-20
Abstract: 947,690. Turbines. UNITED AIRCRAFT CORPORATION. March 20, 1961 [April 4, 1960], No. 10151/61. Heading FIT. An overspeed control for a turbine consists of an arrangement of vanes through which the turbine discharges and which accentuate the swirl of the turbine exhaust as the design speed is exceeded. An increase in pressure is developed across the swirl vanes above the design speed, and the pressure drop across the turbine is reduced, thereby preventing an uncontrolled speed increase. As shown, the turbine 10 exhausts through the annular discharge passage 44 to the outlet 48. The vanes 52, in the speed limiter 14 are shaped to cause a low pressure loss below a design speed and a maximum loss at an overspeed condition.

Title: Centrifugal friction couplings
IPC: F16D43/04
Filed: 1927-04-13
Abstract: 283,380. Stewart, J. F., (Allgemeine Elektricitõts-Ges.). April 31, 1927. Clutches, friction. - In centrifugal friction clutches, particularly for facilitating the starting of short-circuited armature electromotors, the centrifugal masses which effect. clutching between the driving and driven members are, on starting, coupled to the driving-member solely by an auxiliary centrifugal or other friction device, which subsequently does not assist in transmitting torque. The torque transmissible from the main driving-surface, preferably exceeds that transmissible to the driven surface. A driving- member b, Fig. 1, carries auxiliary centrifugal clutch shoes e, coacting with a loose intermediate, member d, which carries on radial guide pins the main centrifugal shoes, a connected together by circumferential retracting-springs (not shown). When the member d has attained a predetermined speed, the shoes a contact by friction casings m, n with conical surfaces on the driveing-member b and driven pulley c, the conicity or radial distance from the shaft axis of these surfaces being preferably different. The masses e may be omitted, and the member d driven by direct friction with the hub of the part b. The surfaces n of the shoes a may, as shown in Fig. 3, coact with a loose coned ring f, provided with a flat friction face p to clutch the pulley c. The ring f may, however, be disposed between the surfaces m and the driving-member b, but the coefficients of friction or radial distances of the driving and driven surfaces should then be chosen to ensure greater transmissible torque from the driving- member. In a modification, the wedging-action between the surfaces m and member b moves the part d axially to clutch a flat surface thereon to the pulley c. In another form, the shoes a, Fig. 8, coact with inclined faces on axially-movable discs f<1>, f<2>, splined to the driving-member b and adapted to grip the pulley c by their faces p', p<2>. The shoe-carrier d may be driven by auxiliary masses e or by direct friction with the bosses of the discs f<1>, f<2>. There may be two or more concentric intermediate members d, d1, Fig. 7, driving one another by friction, the innermost member d being driven by friction with the discs f<1>, f<2> or by auxiliary centrifugal shoes. The action of the shoes a may be further delayed by the drag of spring-pressed pads w, Fig. 8, rubbing on the pulley c. The same effect may be obtained by shoes m, Fig. 11, pressed on the rim d2 of a wheel-like member d by springs r and adjusting- screws s carried by the pulley c, or by loose spherically-faced weights w, Fig. 12, normally housed in recesses in the main weights a and slidable on extensions of the guide-pins l to contact frictionally with the pulley c as soon as the part d rotates. The effect can be adjusted by changing the weights w.
