It appeared to me when studying the matter that the louvres controlling the draught through the radiator were the only really satisfactory means of dealing with the situation. It is possible, however, that by stopping off for the Winter months, a certain portion of the radiator, such as can be done fairly easily between the radiator and the fan, and by passing the water or part of the winter past the radiator, a sufficiently perfect arrangement can be obtained for ordinary fuels and temperature. This is being investigated, but it was quite my impression that it was nearly useless to provide a man with a thermometer to indicate his water temperature without some means of controlling it. It is, however, of considerable use in indicating how much of his radiator he should usually stop off and it was for this purpose that we decided to fit the thermometer which had already been forecasted on the note we circulated re low grade fuels, benzol etc. It will be noticed by the correspondence during the early part of the war, that we strongly advoted for aeroplane work, louvres, shutters, or roller Contd. | ||
