Abstract: 886,144. Magnetic structures. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1960 [Aug. 26, 1959], No. 27812/60. Class 38 (2). A magnetic recording medium has its magnetic constituent held by a rubbery polymeric binder which is cured by sub-atomic radiation providing an absorption of 0.5 to 2.0 megarads in the medium. The medium may be a tape having a polyethylene terephthalate backing bearing fine acicular ferric oxide particles embedded in a binder including a butadiene-acrylonitrile copolymer and a phenolic resin. Tape 12 irradiated on a reel 11 may be held edgewise to the radiation source, the reel 11 being moved during exposure by wobble cam 17 to avoid " shadows." In a continuous process a wide band of base material is coated with a magnetic particle-binder mix by a fountain roller, the coating is smoothed by a blade, and the particles are aligned by a magnet. The band 19 is then dried and split by knife edges at roller 21 into tapes 22a-22e taken up by reels 26a-26e independently driven on spindle 27 and so arranged that the tapes cross under roller 25 where they receive curing radiation in passing source 24. Suitable radiation sources are X-ray generators, electron accelerators or radioactive elements such as radium and <SP>60</SP>Co. Curing is carried to a stage which gives a compromise between wearability, grip of magnetic particles by the binder, flexibility of the tape and " stick " to recording heads.

[Also in Division G3] The collector of a transistor is connected to the collector of another of opposite conductivity type so as to provide a load therefore and D.C. negative feedback is provided from the common collector connection to one of the bases. In Fig. 3 the load of the first stage transistor T 1  is provided by a second transistor T 2  of opposite conductivity type and the operating conditions are stabilized by feedback from the common emitter output stage T 4  to the base of the first stage or to the base of T 2  (Fig. 4, not shown). Fig. 6 shows the application of the invention to a stabilized voltage supply. A reference voltage from a Zener diode is applied to one base of a comparator comprising transistors T 6 , T 1 . The load of transistor T 1  is constituted by transistor T 2  and the output from T 1  is fed through two stages T 3 , T 4  to the series stabilizing transistor T 5 . Feedback from the output through R 9  forms the other input to the comparator. Positive feedback around the comparator may be provided by a resistor R 1 . If R 6  is equal in value to R 3  then, since the emitter voltage of T 2  must be substantially equal to the base voltage, the collector currents of T 1  and T 6  must remain substantially equal and the possibility of transistor T 6  cutting off is reduced. The base of T 2  may alternatively be connected to a potentiometer connoted across the supply (Fig. 5, not shown).
