OXY-ACETYLENE WELDING.-- short course in the practice of oxy-acetylene a has been pre- pared by Alfred A. Kinsey, professor of shop practice at the Stevens Institute of Technology. 'This has been arranged in the form of suggestions for a num- ber of lectures, combined with notes on the operation of the apparatus. These notes and suggestions are published in a most attractive form by the Air Re- duction Sales Co., New York. It is recognized that the course will not make practical welders in 12 lec- tures and the corresponding laboratory periocs. The idea, rather, is similar to that which is the basis of all college shop a first-hand acquaintance of engineering experience. Complete apparatus is specified for the shop work in connection with the course. A color plate teaches the student to judge the correct flame for cutting and welding. The varia- tion in flame color due to an oversupply of oxygen or with an important branch acetylene is made plain. Drawings of welding, cut- ting, and combination welding ana cutting torches make plain the details of the tools, and 'the mixer and pressure regulator device is visualized by a phan- tom photograph. ' POWDERED: FUEL SYSTEM.--The Quigley Fur- nace Specialties Co., New York, has prepared a complete bulletin on ing and firing powdered fuel. tail the types of furnaces to adapted, and explains and_ illustrates the operation. The fundamental idea upon which this system is designed regaras powdered fuel as a fiuid, capable of flowing freely, and subject to control by valves. The preparation of fuel progresses regll- larly through 'several stages controlled by regulating devices which function automatically. From _ the crusher it is elevated to a magnetic separator where tramp iron is removed. It then passes toa crushed fuel bin, thence to a dryer, and by bucket elevator to the fried fuel bin. From this it is fed auto- matically to a pulverizer. A discharge pipe carries it then to a collector 'and _ through this to a pulverized fuel bin. From __ this point it is transported through pipes under air pressure to the mixer at the furnace, The sys- tem provides that the air pressure is behind the fuel and forces it as water is forced by air pressure in a tank. A wide variety of installations are illus- trated and described, and details of parts, dimensions, control features, and comparative of operation are presented, of transporting, stor- This takes up in de- which this fuel is details of its system costs practice--to furnish the students -
