Abstract: Apparatus for making lithographic plates directly from a copy original which comprises, an enclosure which houses a copyboard, an optical train and a carriage. The carriage moves in a horizontal path beneath a platen carrying a sheet of electrophotographic material. The carriage has a corona device, a slit, a toner device including a bias plate and means for withdrawing excess toner.The copyboard is loaded in a horizontal position, is moved to a vertical position where a light scanning assembly moves over its face in synchronism with movement of the carriage. The pattern on the copyboard is projected horizontally into a pit or optical chamber where it is deviated upward to cooperate with the slit.The platen is a cover of the apparatus, can be opened after imaging and toning, the toned electrophotographic member then being removed for further processing.

Abstract: A cutting tool arrangement is disclosed for use in a preprogrammed lathe that comprises a rotary driven chuck holding a workpiece, a rotary turret carrying a plurality of tools and mounted for movement longitudinally of the axis of rotation of the chuck, and a cross slide mounted for movement transversely of the rotational axis of the chuck. The cutting tool arrangement comprises a support member for being mounted on the cross slide, a sliding member mounted on and for sliding movement transversely of the elongate member, said sliding member having mounted thereon at one end thereof a workpiece cutting tool, and a follower member for being mounted on the turret so that upon movement of the turret towards the chuck the follower abuts the sliding member to cause the cutting tool to be swept longitudinally of the workpiece.
