Abstract: A gripper for use in combination with a pin has a body having an axially open cavity in which the pin is engageable. Jaws in the cavity are radially displaceable between an inner holding position bearing radially inwardly on and gripping the pin and an outer release position in which the pin can be removed axially from the cavity. An actuating element in the body is engageable with the jaws and shiftable between end positions corresponding to the inner and outer positions of the jaws. An actuator connected to the actuating element can move it from one of the end positions into the other of the end positions. An externally accessible connecting or operating member on the chuck body is connected through an emergency release with the jaws for moving the jaws into the outer release position as the result of connection to or operation of the member.

Abstract: An outer cylinder arrangement for a low pressure turbine apparatus. The outer cylinder arrangement surrounds a rotor member having an annular array of blades thereon. A manway opening in the outer cylinder permits access into a diffuser channel disposed within the outer cylinder. The diffuser channel is defined by a bearing cone member integral with the outer cylinder and a flow guide member disposed in spaced relationship from the bearing cone within the outer cylinder. The bearing cone has a removable segment thereon which, when removed, permits axial movement of one turbine blade from the annular array of blades into a volume defined by a removal pocket integral with the bearing cone. The flow guide has a removable segment thereon adjacent to the removable bearing cone segment.
