A transistor circuit includes an input transformer T5, having one winding E which carries the direct current taken by the transistor TX4, and a second winding F so connected to a potential divider R3, R4 providing the transistor base bias that the unidirectional fluxes produces by the two windings substantially cancel out preventing saturation. In the amplifier of Fig. 4, resistors R3, R4 control both the base bias of transistor TX4, and also the current through the winding F of transformer T5. The input to the transistor is taken from winding E, and the amplifier output is taken from a secondary winding B on a further transformer T4, a tertiary winding C being connected across the D.C. supply to cancel the flux due to the direct current in the primary winding A. The arrangement may be applied also to oscillators or impedance converters.  The Specification also describes a known arrangement, Fig. 3 (not shown), in which a transistor connected in common emitter configuration has an output transformer which is prevented from saturating by passing a direct current through the secondary winding in opposition to that through the primary.

Abstract: 1,182,806. Loudspeakers. GOODMANS LOUDSPEAKERS Ltd. 14 June, 1968 [14 July, 1967], No. 32456/67. Heading H4J. In a loudspeaker, a magnet 1 is located on the rear side of a steel chassis 5 formed with an aperture 4 (Fis,. 1) for receiving the magnet 1 substantially as large or larger than the magnet 1 thereby providing reduced flux leakage to the chassis. The magnet 1 is located in position by a covering 9 of thermoplastic material having interlocking engagement with the chassis 5 and applied to at least the magnet 1 by the vacuum moulding technqiue. In manufacture, a cylindrical magnet 1 having a front plate 2 is located centrally on a work-table 3 so that its front plate is coaxial with the central circular aperture 4 in the chassis 5. A concentric ring of holes 6 in the chassis 5 has recesses 7 connected to a vacuum passage 8. The thermoplastic covering 9 is placed over the magnet 1 and chassis 5. With the covering 9 heat-softened, vacuum is applied through passage 8 so that the covering 9 is drawn down (Fig. 2), flows into the annular gap 10 between magnet 1 and chassis 5, and into the holes 6 to form "rivet-head" like fastenings. Instead of holes 6, the chassis 5 may have slots or projections around or through which the covering 9 flows and, upon cooling, locks the magnet 1 to the chassis 5. Alternatively, in a two-part process the magnet is encapsulated in thermoplastic material using a forming tool in place of the chassis. The forming tool has recesses shaped to provide the encapsulation with an annular flange carrying rivet-head projections that coincide with a ring of keyhole-shaped slots around the chassis central aperture. By inserting the projections through the keyholes, and by relative rotation, the two units are locked.
