    Abstract: Image defining toner is transferred to cut sheets and fused at one of two fuser stations (21,22). One station (22) is positioned to fuse the image on one side when duplex copying or printing is selected. The other fuser station (21) performs fusing when simplex copying is selected but fuses the second side copy for duplexing. When flash lamps are employed for the fuser station, the lamps are composed of multiple bays with a single power source coupled to each bay in sequence so that the power source size need only accommodate the power level demand of one bay. The time between trigger pulses is extended by commencing fusing with an intermediate bay followed by the initial bay and then the final bay as the image area requiring fusing passes along its path in proximity to the faces of the flash lamp bays.

    Abstract: 1284046 Fluid bearings INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971 [5 March 1970] 22479/71 Heading F2A A fluid bearing for guiding a magnetic tape 13 has a plenum chamber 22 in the wall 23 of which are a plurality of openings 24 to allow fluid to flow from the chamber to support the tape in spaced relationship from the wall, there being an orifice 25 in the chamber to admit fluid from a high pressure fluid source 16. The pressure of the source is such that the rate of flow of fluid to the chamber is constant and independent of the pressure within the chamber. The wall 23 of the plenum chamber is curved so as to define a curved path for the magnetic tape. The fluid is preferably air.
