Title: Determining an Unpredictably Varying Parameter
IPC: G01D1/02
Filed: 1980-01-25
Abstract: An unpredictably varying parameter, is determined by detecting it over a preselected detection period and determining the change in the parameter over a preselected period (n1) and comparing this with the change in the parameter determined over a different preselected period (m1) thereby deriving a signal which is indicative of the comparison. There may be a plurality of detection periods each sufficiently short that the sum of the deviations of the detected linear mean values is less than the desired accuracy. The mean value is determined by linear averaging of the detected linear mean values of all the detection periods. <IMAGE>

Title: Melting inorganic materials
IPC: C03B5/43
Filed: 1981-02-11
Abstract: A process for the continuous and controlled melting of essentially non-metallic inorganic material, especially oxides, for manufacturing mineral fibres, which uses a sealed vessel with a refractory lining and electrical heating means and contains a liquid bath with a mass of at least 8 tonnes, the melt being continuously withdrawn from this bath at a flow rate of less than half the total mass of the bath per hour and the bath being replenished as a function of the said flow, e.g. at the same flow rate.
