Show I 1 av I 1 IR M LLA NY 1 the smoke problem seems to have been solved for factories in a very satisfactory is way by an austrian engineer herr fritz maler maier the solution depends upon closed furnace doors and slow feeding without admission of air from above and it is effected by means of an automatic stoker which drops the fuel in small quantities on the front end of the fire and anther automatic arrangement that shovels the fuel along the fire the apparatus is cooled by water which as it becomes heated is used to feed the boiler perfect combustion is claimed and a trial of six months in a factory near vienna is reported to have resulted in a saving of 33 per cent in fuel and 90 per cent in labor one stoker doing the work of ten what he calls the sense of return in pigeons

laboratory method of drying ur air by mens means of a mols ture absorbing agent has been borrowed by a frankfort inventor tor for a patented dry barrel or box for preserving vegetables and other substances the new apparatus is simply a box with a false bottom of slats under which to is placed a metallic tray containing caustic potash the vegetables fruit etc are placed on the false bottom and the air admitted onar through the bottom is dried before reaching them by passage over olver the potash one charge of the drier is in claimed to last six months an indestructible ink for writing ung
