Title: Method of controlling parallel operation of tapped transformers in master-follower relationship
Inventor: KUGLER KURT
IPC: H01F29/02
Filed: 1987-04-02
Abstract: A method of controlling parallel operation of tapped transformers in master-follower relationship is able to control transformers with unequal voltage taps. The data of all possible voltage taps of each transformer is deposited as a characteristic value and as voltage range in coding units (A1) and one of the transformers is assigned a master function through individual connection to an automatic regulating system (C1). The characteristic value of the instantaneous tap setting of the master transformer is fed to a data bus (B) which is connected by means of a respective switch (S2) with a comparison unit (A2) of each follower transformer. It is ascertained in the comparison unit of each follower transformer whether the characteristic value of the voltage tap of the master transformer agrees, in terms of voltage range, with the voltage tap present at the follower transformer. If this is not the case, the motor drive (MA) of the <IMAGE>

Title: Method of making articles from magnetically hard ferrites and a device for comminuting magnetically hard ferrites
Inventor: ABROSIMOV VLADIMIR ALEXANDROVI
IPC: H01F41/02
Filed: 1989-11-02
Abstract: In a method of making articles from magnetically hard ferrites the initial calcined ferrite is magnetized prior to comminution. Calcined ferrite granules are fed from a hopper 16 through a magnetising field produced by a winding 13 and conveyed by the alternating field of a winding 12 to a container 1 supplied with water from a vessel 5 via a pump 6. The magnetic field produced by a winding 10 causes the granules to collide and comminute thereby forming a suspension which is fed to the vessel 5.

Title: Separating device for root crop harvesters
Inventor: SCOTT JAMES ROY
IPC: A01D17/06
Filed: 1989-12-19
Abstract: A roller table separating device 3 fitted to a root crop harvester is mounted to allow ready adjustment of longitudinal operating angle of table to suit crop conditions. Adjustment is by actuators controlled either manually by operator or by automatic level sensors pre-set to relate table angle to horizontal irrespective of angle of slope being traversed in work. Due to the relative position of pivot points of the roller table, and the linkage of roller table to feed conveyor 1, the height of drop of the crop from feed conveyor to table and from table to loading conveyor is minimum and is maintained so, thereby reducing possibility of crop bruising/damage at that point. <IMAGE>
