Abstract

1480590 Oscillating motors LUCAS INDUSTRIES Ltd 17 Oct 1974 [26 Get 1973] 49964/73 Addition to 1352127 Heading H2A The motor disclosed in the parent Specification is modified by including in the permanent magnet a plate of magnetizable material extending substantially normally to the direction of polarization of the magnet. The magnet may be disposed between two steel plates (Fig. 7, not shown) or preferably the magnet is split into two halves separated by a single steel plate (Fig. 6, not shown).
