Abstract: An organoleptically acceptable antacid lozenge including at least one antacid present in the form of micronized particles having a particle size of less than about 10 microns. The lozenge is a solid oral composition capable of dissolving slowly in the mouth for long lasting administration of an antacid at a sustained or slow release rate. The lozenge is non-gritty, smooth textured, and does not irritate the oral mucosa.

Abstract: The present invention provides an organoleptically pleasing lozenge containing an antitussive selected from the group consisting of dextromethorphan, diphenhydramine, caramiphen, carbapentane, ethylmorphine, noscapine, codeine, and mixtures thereof, complexed with an ion exchange resin wherein the particle size of the resin is 38 ?m or less in diameter. Also provided is a process for producing the lozenge and methods of administering the lozenge.

Abstract: The position of a fault occurring in an electric power transmission line (1) is determined by "labelling" a voltage or current pulse originating from the fault and reflected by the end of the line, or some other point in the system, moving back towards the fault, and then measuring the time taken for the labelled pulse to return to the measuring point near the end of line. The "labelling" is achieved by predicting from known data and the time of arrival of the reflected pulse the amplitude of the voltage pulse and comparing the prediction with the measured value. Apparatus for carrying out the method is described.
