Image movement correction is provided in a field conversion television system by deriving simultaneously two fields of a selected number of lines from an original single field and vertically shifting one of the derived fields by 0.5 lines. A movement vector is determined for each field and movement correction is performed based on a current field and a preceding field, in the case of a moving object in the image. If no moving object is present linear approximation is employed to correct for motion caused by the field number conversion. Two memory systems are provided for the two simultaneous fields and also to selectively obtain specific horizontal lines of the current and preceding fields, relative to both simultaneous derived fields. Ultimate selection of a field for display is based upon the detected movement vector.

In an electric discharge machining apparatus with a wire-shaped electrode for machining a workpiece by causing electrical discharge in a gap between the wire-shaped electrode and the workpiece and controlling a machining feed speed so that the voltage across the gap is constant, the machining area of the workpiece is detected from the machining feed speed. The thus detected data representative of the machining area are applied to an arithmetic unit which operates to instruct optimum electrical machining conditions according to the machining area, whereby the workpiece is machined under the optimum electrical conditions at all times.

A mobile type auto-doffer for ring spinning machines and the like consists of a doffing device and a donning device with mechanisms similar to those of a doffing device. The operation for doffing full bobbins may be carried out by utilizing the doffing device, and the operation for donning fresh bobbins may be carried out by utilizing the donning device. During the doffing operation, a plurality of full bobbins is simultaneously transported from the spindles to the pegs disposed between the spindle rail of the spinning machine and the surface of the floor of a spinning plant. During the donning operation, the same number of fresh bobbins as that of a full bobbins is simultaneously transported from the pegs to the spindles. Both of the above-mentioned ways of transporting bobbins may be carried out by moving the full bobbins or the fresh bobbins along separate vertical passages, respectively, i.e., one passage being disposed farther from the row of spindles than the other passage. The vertical movement of bobbins can be induced by the sliding movement of swing arms along a corresponding spline shaft. The horizontal movement of the doffing head of the doffing device as well as the horizontal movement of the donning head of the donning device can be induced by the swinging movement of the swing arms. The horizontal and vertical movements of the doffing head of the doffing device and the horizontal and vertical movements of the donning head of the donning devices can be controlled and effected by means of hydraulic mechanisms, respectively. In addition, the action of holding full or fresh bobbins by means of a plurality of cop holders mounted on both the doffing and donning heads, can also be controlled and effected by means of hydraulic mechanisms.
