Abstract

9499. Siemens & Halske Akt.-Ges. April 21, 1911, [Convention date]. R÷ntgen-ray apparatus.-The excitation of a R÷ntgen-ray tube is produced by suddenly commutating the continuous current flowing in the primary windings of a transformer or induction coil. Rapid successive discharges are obtained by means of an interrupter or a rectifier for the secondary current in conjunction with a rotating commutator of the transformer or induction coil. Fig. 1 shows apparatus for a single discharge in which the current in the primary winding p is increased as the arm 1 is moved over and the resistances 9 are cut out. The current is reversed when at its maximum strength as the arm passes over the insulated block 13, and is reduced to its normal value as the corresponding resistances 9<a> are switched in. Fig. 2 shows the use of a commutator K with an interruptor S, whose moving parts 25, 26 are driven synchronously with the commutator, and arranged so that current passes through the secondary s only when the primary current is being commuted in one given direction. Alternatively, a rectifier may be used in the secondary circuit arranged so that the impulses due to the commutations of the current in both directions can be utilized.
