Abstract: An electric sound producing device includes a ferromagnetic diaphragm, an electromagnet for deforming the diaphragm and an oscillator for repeatedly supplying short duration current pulses to the electromagnets. The oscillator may be driven by a multivibrator to produce intermittent sound pulses or by a sawtooth pulse generator to produce sound with an apparently cyclically varying frequency.

Abstract: An electro-magnetic torque motor has a permanent magnet pivotally mounted in a hollow frame of magnetisable material. Surrounding the magnet within the frame is a winding whose magnetic axis is angularly displaced from the magnetic axis of the magnet when the winding is not energised. Energisation of the winding tends to rotate the magnet within the winding in a direction to align the magnetic axes.

Abstract: A collapsible and portable device for supporting part of the weight of a child to permit the child to jump up and down and to walk about a central upright column. The device includes a collapsible stand for positioning on a floor and a cantilever and resilient suspension mechanism coupled to the stand such that the mechanism may be rotated about the column. A seat is releasably coupled to the suspension mechanism so that when the child is placed in the seat, a proportion of the child''s weight is supported by the device and the child is free to jump up and down and to move in a circle about the column.
