Abstract: Weighing apparatus includes support means to support the article to be weighed, a pair of screws fixedly mounted on the support means and a base member movable relative to the screws between a first position in which the base member is spaced from the bottom of the article and a second position in which the base member is in contact with the article. Screw receiving members are threadably mounted on the screws and are connected to the base member. Upon rotation of the screw receiving members, the base member is moved between the first and second positions.

Abstract: An apparatus and method for sensing electro-magnetic radiation and analysing the resultant electrical signal waveform, in order to determine whether the radiation originates from a fire condition, monitors variations in the signal waveform over a predetermined period of time. The amplitudes of the successive transitions in the waveform and the elapsed time between the transitions are measured. Two two-dimensional matrices are produced. The first of these is made up of a plurality of co-ordinate points each corresponding to a respective pair of successively occurring signal transitions. The position of each such point in the matrix is dependent on the respective amplitudes of the two transitions making up each pair. The second matrix is also made up of a plurality of co-ordinate points each corresponding to a respective pair of the signal transitions.
