    Abstract: This invention provides in or for apparatus for parting cylindricoidal workpieces by rolling, a plurality of cutting rollers arranged on coincident axes and stop means which are arranged to contact the ends of a workpiece when the cutting rollers engage the surface of the workpiece to prevent the workpiece spreading axially during the cutting operation. The apparatus preferably further comprises means for rotating the cutting rollers and the workpiece and means for so moving the workpiece and the cutting rollers so that their axes approach at high speeds.

    Abstract: This invention relates to methods of rock breaking which comprise orbiting small rollers around a backing roller that is urged towards the rock face. The rollers each have a raised working zone which is preferably circular in section and which may have hard metal inserts. The rollers may be moved in an arc over the rock face or may be moved stepwise thereof. The working zones apply substantial localized forces to the rock face which forces cause the rock face to break.

    Abstract: This invention relates to methods and apparatus for forming annular articles such as the outer bearing races for taper roller bearings which are profiled internally and in a radial plane of the members. The material is rolled on to a multipart mandrel and is cut therefrom. The mandrel parts are removed individually.

    Abstract: This invention relates to rolling of annular workpieces by means of apparatus comprising a pressure roller, a mandrel which squeezes the workpiece against the pressure roller and backing rollers on which the mandrel rolls in line contact. Either the backing rollers or the pressure roller can be formed in two parts which can be adjusted towards and away from each other, either before or during rolling.
