Abstract
759,938. Air-blast switches. ETABLISSEMENTS MERLIN & GERIN, SOC. ANON. Jan. 4, 1954 [Jan. 13, 1953], No. 123/54. Class 38(5) A pneumatic blow-out arrangement for .circuit-breakers comprises a nozzle of flat eliptical shape or in the form of a flattened cylinder or of a slot, or several spaced holes in a nozzle cap (Figs. 3-5, not shown), for producing a fan-shaped jet of air, Fig. 2 ,by which the arc is displaced upon horns 1, 2 into a chamber comprising arc splitting plates 3.
