Title: Control system for profiling and embankment excavator - has angle sensors for generating data for automatic operation (NL 15.11.77)
Inventor: LORENZ JOERG DR ING
IPC: E02F9/26
Filed: 1976-05-11
Abstract: The control system is used for position indication and for automatic position regulation of the excavating scoop. The latter is used in hydraulically operated earthmoving machines with overhaning articulated arm for ground profiling and for making of sloping embankments. The instantaneous position of the scoop is indicated directly on the operating stand. Manual operation requires only one movement and scoop movements are automatically controlled, to ensure that an embankment with specified slope can be correctly excavated. The overhanging arem (4), shank (7) and scoop (10) angles are measured by angle transducers, and angles are fed into the computer. The latter computes from this, information and constant values, the overhang and the scoop cutting angle. The computation result is displayed and compared with the actual value of the excavation. The difference between the actual and requried value generated pulses for actuatinng solenoid valves. These valves regulate automatically movements of all other components when e.g. only the scoop is manually controlled.

Title: Stepping motor with salient pole stator - has excitation coils mounted on limbs instead of salient poles
Inventor: HUBER ERNST
IPC: H02K37/14
Filed: 1976-09-30
Abstract: A stepping motor with salient pole stator, with improved use of the construction material has a stator of laminated construction with typically four salient poles (P) joined by yoke sections (J) giving a square outline. The excitation coils (Ia, Ib, IIa, IIb) are located on the yoke limbs instead of the salient poles. The space available is thus better utilised and larger coils giving freater flux density can be employed without increase in active core material. Diametrically opposite coils are connected in series. The rotor can be made of a ceramic magnet having two poles in the case were a four pole stator is employed. In the non-magnetised axis, the ceramic has approximately the same reluctance as air, thus the assembly need not be particularly accurate with respect to radial air gaps between stator and rotor.
