Abstract
759,798. Liquid-blast switches. ALLISCHALMERS MANUFACTURING CO. April 21, 1954 [April 27, 1953], No. 11562/54. Class 38(5) In a circuitbreaker as described in Specification 759,794, the a r c - quenching structure 36 is formed of superimposed insulating plates forming helical flow passages 120 and venting passages 118, 119, some of the openings in the discs' having barriers 130 to confine the flow more closely to the arc passageway 32. Specifications 759,795, 759,796 and 759,797 also are referred to.
