The invention relates to a turbine (1) having a rotor (2), which has a bladed area (3) for rotor blades (4) and a thrust compensation piston (5). The thrust compensation piston (5) has a hot side (6), which faces the bladed area (3), and a cold side (7), which is remote from the bladed area (3). On
The invention relates to a turbine (1) having a rotor (2), which has a bladed area (3) for rotor blades (4) and a thrust compensation piston (5). The thrust compensation piston (5) has a hot side (6), which faces the bladed area (3), and a cold side (7), which is remote from the bladed area (3). On one side, a feed (14) for sealing fluid (15), which is assigned to the cold side (7), and a leakage fluid feed (12), which is flow-connected to the bladed area (3), open out into a mixing area (13), and on the other side a discharge line (16) branches off from the mixing area. The invention also relates to a method for discharging hot leakage fluid (17). In a turbine (1), the leakage fluid (17) passes through a radial gap (12) between a thrust compensation piston (5) of a rotor (2) and a stationary turbine part (11) and is mixed with a cooler sealing fluid (15) and discharged.

The device for securing a container to a hoist of claim 5 wherein said hook engagement member includes said actuator having a hook bar sized and configured to engage with and rotate said hooks from the activated, locking position to the retracted, unlocked position when said actuator rotates from the activating position to the retracting position. 7. The device for securing a container to a hoist of claim 6 wherein each of said hooks includes a control arm extending laterally between said hooks to be engageable by the hook bar. 8. The device for securing a container to a hoist of claim 7 wherein each of said coil springs includes a first terminal arm that is operationally connected with one of said hooks to bias said one of said hooks toward the activated, locking position. 9. The device for securing a container to a hoist of claim 8 wherein each of said coil springs includes a second terminal arm that is operationally connected with said actuator to maintain the bias of the spring upon said one of said hooks. 10. The device for securing a container to a hoist of claim 9 wherein said actuator includes a spring bar sized and configured to engage with the second terminal arms. 11. The device for securing a container to a hoist of claim 10 wherein said actuator means includes a pneumatic cylinder mounted to said frame and having a piston rod with an outboard end connected to said actuator to move said actuator between the activating position and the retracting position. 12. The device for securing a container to a hoist of claim 5 wherein said actuator further includes a control fin sized and configured to engage with said hooks, and wherein said springs are disposed on opposite sides of the control fin. 13. The device for securing a container to a hoist of claim 12 wherein the control fin includes a hook bar sized and configured to engage with and rotate said hooks from the activated, locking position to the retracted, unlocked position when said actuator rotates from the activating position to the retracting position. 14. The device for securing a container to a hoist of claim 13 wherein said actuator further includes a spring bar and wherein each of said springs includes first and second terminal arms, the second terminal arms engaged with the spring bar and the first terminal arms engaged with said hooks to urge said hooks toward the activated, locking position. 15. The device for securing a container to a hoist of claim 1 further wherein said frame defines an uppermost surface and wherein the retracted, unlocked position includes the entirety of said hooks being at or below the uppermost surface of said frame. 16. The device for securing a container to a hoist of claim 1 wherein said hooks rotate approximately 99 degrees between the retracted, unlocked position and the activated, locking position. 17. A device for securing a container to a hoist, the container having at least one long sill, comprising: a frame rigidly connectable to a hoist; first and second hooks mounted to said frame to rotate about an axis between a retracted, unlocked position away from the long sill of a container and an activated, locking position disposed at least partially over the long sill; an actuator mounted to said frame to move between an activating position and a retracting position; a hook engagement member operationally connected between said hooks and said actuator to limit the rotation of said each of said hooks toward the activated, locking position as a function of the position of said actuator; biasing means operationally connected with said hooks for urging said hooks toward the activated, locking position; and, power means connected with said actuator to move said actuator between the activating and retracting positions. 18. The device for securing a container to a hoist of claim 17 wherein said hooks are mounted to said frame in mutually close proximity. 19. The device for securing
