12,940. Goldsborough, R. H. June 22 Stuffing-boxes, substitutes f o r.-In turbines, leakage between the rotor and casing is pre vented by rings 53 of relatively soft material, such as aluminium or copper, placed in grooves 52 in the casing. The clearance can thus be made very small, as distortion of the rotor only brings it into o contact with these soft rings.
