    Abstract: 1,232,999. Bearings. NATIONAL RESEARCH DEVELOPMENT CORP. 11 Sept., 1968 [18 Sept., 1967], No. 42403/67. Heading F2A. A hydrodynamic bearing comprises electromagnetic means consisting of radially-arranged polepieces 4a-4f and windings 5a-5f surrounding a magnetically-permeable cylinder 9; this arrangement causes vibration of one bearing member 8 relative to the other 6 in a direction which includes a component normal to the bearing surfaces such that there is an increase in pressure in the gas film between the bearing surfaces which maintains the bearing clearance. Adjacent pairs of polepieces may be wired in series such that they are of opposite polarity, each pair being connected to each phase of a three-phase A.C. supply.

    Abstract: 1,187,777. Storing liquids in flexible tanks. NATIONAL RESEARCH DEVELOPMENT CORP. 30 June, 1967 [1 July, 1966], No. 29634/66. Heading E1H. An installation for storing liquids comprises a pit with an upwardly-open recess and a tank 10 for the liquid to be stored, the tank being received within the recess and having top 11, side 12 and bottom 13 walls of flexible sheet material and rain-water, river-water sea-water or other liquid 23 continuously present within the recess beneath the bottom wall 13 of the tank. The recess may be lined by water-impermeable sheet material 17 which is apertured so that the pit communicates with an overflow pipe 25 which limits the height to which the liquid within the recess outside the tank can rise within the recess.
