Title: Visual teaching and learning slide projector - has built-in shutter in proximity of objective
Inventor: SCHEUERER JAKOB
IPC: G09B5/02
Filed: 1973-09-17

Title: Pulse actuated precision gear cutting machine - uses rotating signal generators for cutter and workpiece
Inventor: FLECK HANS GUENTHER DIPL ING
IPC: B23F23/10
Filed: 1974-09-20
Abstract: A gear cutting machine tool has a control system ensuring high cutting accuracy by reliable and relatively simple means. The required number of teeth for a gear wheel are cut without the use of change gears, by using a selector switch system instead. The rotating signal generator (3) generates pulses per revolution whose numbers differ by a constant value or by an even multiple. The parallel movement device has a pulse comparator which compares only the cutter rotating signal generator (3) pulses which correspond only to the required number of teeth of the workpiece (8). The signal pulse is processed with respect to the position of its leading flank and the position of the leading flank of the pulse provided by the workpiece rotating signal generator. This arrangement ensures the synchronous running of the drive in relation to the pulse leading flank.
