    摘要: A mouthpiece for use in an inhaler for a particulate medicament, the mouthpiece having: an inlet and an outlet for the particulate medicament; a number of abutments which extend across the mouthpiece and which are arranged in a staggered configuration such that, in use, medicament is caused to break up as the medicament passes through the mouthpiece; wherein the abutments are blades having an elongate cross section in the direction of travel of the medicament.

    摘要: A fire suppressant powder with particle sizes less than 5 .mu.m is made by a chemical reaction between a gas or vapour of a first material and a vapour or an aerosol of a second material. For example an aerosol of sodium hydroxide droplets may be reacted with carbon dioxide gas to produce sodium bicarbonate powder; or boron halide vapour may be reacted with steam to form boric acid powder The powder may be used in fire extinguishers either on its own, or combined with other ingredients such as silica and/or alumina, and calcium stearate.
