Title: Method for measuring heat pattern during sintering
Inventor: YANAKA HIDEOMI
IPC: C22B1/20
Filed: 1984-07-17
Abstract: PURPOSE:To obtain heat history during sintering by on-line measurement in a sintering process in a Dwight-Lloyd sintering apparatus by measuring a change in the surface position of a sintering bed in the direction of the height and estimating the position of the flame front at an arbitrary position. CONSTITUTION:In a sintering process in a Dwight-Lloyd sintering apparatus 1, a change in the surface position of a sintering bed 4' in the direction of the height is measured. A point D at which the height of the bed 4' is fixed in the ore discharge part is considered to be a position D at which the heat front HF reaches the surface of the grate. The heat front HF in the range from a position B at which the bed 4' is fired to the position D at which the heat front HF reaches the surface of the grate is estimated from the surface position of the bed 4'.

Title: Electric energy supply device with through type current transformer
Inventor: HANSU YOAHIMU FURAIGANGU
IPC: H02B11/26
Filed: 1979-11-13
Abstract: The power supply system has several adjacent current conductors forming single-conductor transformers with iron iron cores carrying secondary windings. To avoid the adjacent conductors affecting the fault behaviour of the transformers involved, a screen (15-17) is located between the iron cores (6-8) and the adjacent conductors (3-8). The screen is made of ferromagnetic and/or electrically conducting material. The screen prevents the design errors or faults of one transformer being affected by an adjacent transformer. This means that these errors or faults behave in a predetermined way and can be compensated for.

     CONSTITUTION: In a solution of not less than 1wt% of a polymer surfactant of 2000W20000 in average molecular weight of a styrene-maleic acid copolymer derivative shown by formula [I] and magnetic powder, magnetic powder is dipped to adsorb the above-mentioned surfactant. After this magnetic powder is taken out and dried, a magnetic coating obtained by dispersing it in a solution containing a binder [copolymer of vinyl chloride and vinyl acetate and hardner (urethane resin, etc.)] is applied on a base body of a polyester film, etc., and dried to manufacture a magnetic tape. In this way, binding capacity between the magnetic powder and binder is strengthened without leaching the surfactant from the tape surface.
