Abstract

1,265,885. Bearings. RANK ORGANISATION Ltd. 3 June, 1970 [11 June, 1969], No. 29633/69. Heading F2A. [Also in Division G2] A carriage 5 for carrying a lens A is supported by means of pressurized-gas in a body 6. The carriage 5 is provided with three circumferentially-spaced pads 5a at one end thereof and with three circumferentially-spaced pads 5b at the other end. Each pad is provided with a pocket 2 which connects, via a radial passage 1 and an axial passage 4 which are formed in the carriage 5, with a manifold 3. The latter is closed by means of a plate 8, having an inlet (not shown) therein through which pressurized-gas in a closed circuit is supplied. In a modification each pad is provided with grooves 14, 15 and a return channel 16. The channel 16 may be connected to the suction side of a pump, via a manifold (not shown).
