Abstract: A reluctance machine has a stator with a plurality of stator poles arranged tangentially one after the other and carries at least one stator winding. The rotor has a plurality of pole pairs equally angularly spaced. The rotor has an equalizing winding composed of coils in the form of a hollow cylinder of conductive material provided with longitudinal slots extending alternately from opposite ends receiving the rotor poles, the parts of the cylinder between the slots being joined at alternate ends by arcuate parts, the induced voltages in the coils counteracting each other.

Abstract: Disclosed herein is a current control system for a static converter. The converter has an inductive load object connected to its DC terminals and has a plurality of controllable rectifiers with a firing pulse generator connected to the rectifiers for supplying firing pulses thereto in a predetermined commutation sequence. The control system has a current sensing device for sensing the DC load current of the converter. A function generator computes, on the basis of this current, during each interval between consecutive firing pulses, a predicted load current value. This predicted value at each moment during one of said intervals corresponds to the load current, which is obtained during the next one of said intervals, if the next firing pulse in the commutation sequence is supplied at that moment. The predicted value is compared with a current reference value. When these two quantitites become equal the next firing pulse is supplied.

Abstract: Grinding mills for wood wherein the wood is fed to a grinding stone require regulation to produce pulp of good quality. A signal measuring the friction coefficient between the wood and grinding stone is derived and this signal controls the wood feeding to keep the friction coefficient constant.

Abstract: An information system includes an information carrier and a reading unit. The information carrier includes an inner and an outer layer, the outer layer constituting a protective casing surrounding the inner layer and hiding the information. The inner part is formed of at least one electrically conducting closed loop in which an electrical current is intended to be induced, this loop having a plurality of openings therein in the same plane. These openings are so positioned that at least two parallel current paths are produced partly in the loop. One of the current paths is decreased in its average area by at least one interruption so that the other current path will carry the main part of the current induced through the loops. A combination of these interruptions forms the information on the carrier. The reading units include an arrangement for detecting differences in the currents in said paths.
