摘要： A machine for forming gears and the like comprises a workpiece support continuously rotatable about a first axis, a tool support angularly displaceable about a second axis and constructed to support a tool for rotation about a third axis angled to the first axis and an electrical master-slave servo system having a master providing a first electrical signal defining a required angular displacement for the tool support and a second electrical signal for influencing the continuous rotation of the workpiece support in dependence upon the angular displacement defined by the first signal.

摘要： A device for testing the wrappers of cigarettes for leaks comprises a conveyor arranged to carry the cigarettes successively through a test region, means defining in the tests region a plurality of similar test chambers partly bounded by the respective cigarette wrapper, a source of pressure which communicates with each test chamber in turn at a first station in the test region to produce a predetermined initial pressure in each test chamber, and a pressure detector arranged to detect the pressure left in each test chamber in turn at a second station in the test region downstream of the first station.
