Abstract

1,258,539. Cleaning magnetic disc records. BURROUGHS CORP. 1 April, 1970 [13 June, 1969], No. 15325/70. Heading G5R. Rotation of a disc in an enclosure causes the static pressure of the enclosed fluid to vary from one point to another; a higher-pressure area 30 is connected to a lower-pressure area 31 by an external conduit containing a filter 33 which collects dust particles over a certain size.
