283,106. Otto, W. Jan. 3, 1927, [Convention, date]. Cut-out arrangements. -A safety device for R÷ntgen ray apparatus comprises an electromagnetic switch c with its operating coil s located in the connection to earth of the casing b of the the high-tension transformer i, a supplying the tube r and controrling the lowtension supply p. If a person f accidentally comes into contact with a live part of the tube, the resulting leakage current, from one pole of the secondary to earth at e, passes through the coil s and through the capacity constituted by the casing b and the secondary a of the transformer to the other pole. Consequently the switch c is opened and the supply to the tube is cut off.
