Title: Power-operated lathe chuck - has coupling body coupled to thrust washer via radial driving dog allowing sliding movement
Inventor: PESCH KARL
IPC: B23Q3/12
Filed: 1991-05-07
Abstract: The power-operated chuck secures work or tools to a hollow lathe spindle, in which a clamping bar (19) slides axially, having a coupling (21) to a central axial clamping member (20). Between the spindle and the chuck is a clamping head (2), with a body (2.1) fixed to the spindle and through which the bar passes. Adjustable locking members (6) secure the chuck, and are actuated by a thrust washer (12) rotating in the head body on the spindle axis (3). The locking members engage in mountings (7) in the chuck, to pull it centrally against the clamping head. The coupling has a body (22) turning but not sliding on the bar, and turned between coupling and uncoupling positions. It is coupled to the washer via a driving dog (30) extending radially through an opening in the clamping-head body, so that the two rotate together and can slide axially in relation to each other. The angular interval between the engaged and free positions of the washer is the same as that for the coupling body. USE/ADVANTAGE - On manual operation of the washer, the clamping member and bar engage together.

Patent DE-4237050-A1 (DE)
Inventor: WARTH HELMUT
IPC: F04D13/04
Filed: 1992-11-03
Abstract: In the state of the art, sludgers for pumping visquous fluids in which a lower viscosity solvent liquid is added to the fluid are filled with the visquous fluid when they are sunk into the borehole. In order to start the sludger, therefore, a high starting torque caused by the unmixed visquous fluid must be overcome. In order to reduce the starting torque, a shutting-off device (19) is arranged before the actual pump inlet (18) for closing the sludger during sinking and preventing the entrance of visquous fluid. The shutting-off device is particularly useful for a turbopump in which the driving liquid of the turbine is used as liquid solvent, whereas the shutting-off device is hydraulically actuated by means of the driving liquid.
