Abstract

538,364. Heat treatment of metals; spray nozzles. BUDD INDUCTION HEATING. Inc. Jan. 3, 1940, No. 201. Convention date, Jan. 11, 1939, [Class 72] [Also in Group XXIX] The internal surfaces of cylindrical bodies which may be heated by the method described in Specification 503,130 are quenched by impinging thereon a plurality of substantially radially directed streams of quenching fluid so arranged that the centre of impingement of each stream at the surface is equally spaced axially and circumferentially from the centre of impingement of each adjacent stream. Fig. 1 shows a nozzle for this purpose comprising a tube 10 having a plurality of ports 24 arranged in circular bends 26 uniformly spaced along the length of the nozzle. The bands are situated in annular grooves 40 the walls 42 of which are coned to guide fluid into the jets 24. A central pin 12 formed in steps effects equal distribution of the fluid to the bands 26.
