Abstract
18,540. Piolunkowski, M. Sept. 11, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Etching.-In apparatus for etching metal plates &c. the etching-fluid is forced under pressure from a reservoir b through nozzles a against the under surface of the plate A. At the central narrow part d of the nozzle bore, downwardly-inclined airducks d<2> communicate with a compressed-air chamber e. The velocity of the spray and its degree of subdivision may be determined by varying the pressures in the chambers b, e. Water may be admitted to the reservoir b for washing the plate. The etching or washing fluid is removed by the pipe r. The rate of discharge is stated to be a maximum when the velocity of the liquid at the narrowest part of the bore is equal to the velocity of sound in air or about three hundred and thirtythree meters per second.
