Abstract

1322355 Fluid operated rams NATIONAL RESEARCH DEVELOPMENT CORP 11 Aug 1971 [21 Aug 1970] 40508/70 Heading F1D [Also in Division B3] A fluid-operated actuator comprises a ram 7 for supporting a semi-conductor 3 for cutting by blades 1, the ram being supported in a ram chamber 9 by gaseous or liquid fluid and being guided vertically by a compressed air bearing 8 through which the ram passes. The bearing 8 includes two pairs of opposed plates 12, 13 which contain air jets 14 for providing a compressed air interface between the bearing and ram. The chamber 9 and bearing 8 have flanges 21, 20 which are joined together. The bearing is surrounded by bellows 27 to prevent air from the bearing interfering with the cutting operation. Gas is supplied to chamber 9 through an aperture 22 at the bottom thereof.
