Abstract

<PICT:0711750/IV (a)/1> A ball-float for use in, e.g. a flushing cistern, is made from thermo-plastic material, e.g. polyvinyl chloride, moulded in separate hemispherical halves 1, 2, having flanges 3 which are welded together. One half 2 has moulded in situ in a sunken boss 4 a screwthreaded brass socket 5 for the attachment of the float lever.
