These furnaces have hearths 25 ft. in length and 46 in. wide and may be charged or discharged from either end. For annealing there are two stationary floor level furnaces and two car type furnaces. The former have hearths 10 ft. wide and 20 ft. in length and are used for pipe and pot annealing of high-carbon steels and various high-carbon alloys, both in electric and open-hearth steels. Straight bars up to 20 ft. in length are placed in pipe 6 and 8 in. in diameter. One end of the pipe is placed in a pit 12 ft. deep, 8 ft. long and 6 ft. wide, adjoining a platform, and is filled with bars and packed with charcoal from this platform.

The cars are 29 ft. long and have five sets of wheels, all running on Hyatt roller bearings. Located near the furnaces is an oil quenching tank 30 ft. long, 6 ft. wide and 6 ft. deep, used principally for quenching heavy forgings. The blast for the furnaces is supplied by two No. 10 Sturtevant fans arranged in duplicate, so that either may operate the entire plant. Each unit is driven by a 60-hp. motor. Air is supplied at 10 oz. pressure, and gas at 12 oz. pressure. All air blast, gas and water lines and pyrometer leads and electrical wires are carried through the plant in a concrete and brick conduit covered with cast- iron plates. The main gas lines are equipped with quick closing valves, which automatically close if the power goes off the blowers. These valves, to- gether with check valves on the air lines, are safety devices installed to prevent explosions. The temperatures of all furnaces are taken and observations are made at a control board in the department office, the board operator flashing sig- nals to the furnace operator by red, white and green lights. The furnaces are equipped with base metal thermocouples with nichrome protecting tubes. The control station is provided with a bus- bar board, so that connections can be 1 continuous record on a 10-point recording instru- ment of any 10 thermocouples in the plant.

W. Parr, professor of applied chemistry, University of Illinois, Urbana, IIlL., issued by the Engineering Experiment Station of that school, and No. 136, by Horace C. Porter and F. K Ovitz, Bureau of Mines, Washington, have been issued. The former deals with bituminous coal of the Illinois type and the latter covers tests made on New River, W. Va., and Pocahontas semi-bituminous coal, Pitts- burgh gas coal and Sheridan, Wyo., sub-bituminous coal. Results from experiments at the University of Illi- nois, begun in 1910 and recently completed, indicate that coal in storage increases in weight due to the absorption of oxygen, and Professor Parr ascribes indi- cated heat losses per pound of fuel largely to this. Porter and Ovitz, using Pittsburgh coal, found little, if any, change in weight over a five-year period of outdoor exposure, but explain that laboratory experi- ments have shown such increhses in weight and that net heat losses may be slightly less than indicated on this account. Conclusions of both investigations are that actual heat losses due to deterioration of the coal are small, the maximum loss as determined by the Bureau of Mines being 5.5 per cent in three years for Wyoming coal, while for the other coals losses did not exceed 2.1 per cent in two years. Storage in open bins was found by the University of Illinois to effect consistently lower percentage losses of heat value than storage under cover, and the Bureau of Mines concludes that, in the storage of Sheridan coal for more than three months, the use of covering bins is not as advantageous as that of air-tight bottoms and sides and the accumulation of fine slack on the surface Professor Parr recommends that in dry storage all fine material be screened out and that only the lump coal, preferably sized, be stored. An increase in fines or slack was found in both investigations to result from storage, the Bureau of Mines finding this more preva- lent in open than in closed bins. gas The Asbestos Protected Metal Co., Pittsburgh, an- neunces that it will be represented in Georgia by J.

The one which is most apparent is the hoisting attachment for handling heavy pieces of the work, al- though others are the dust exhaust system and the means for the adaptation of the machine for direct connected motor drive. The machine is equipped with a disk wheel 53 in. in diameter and is designed for heavy grinding work This wheel is supported by a cast-iron flange 20 in. in diameter and 1% in. thick located on the upper end of a vertical spindle 35% in. in diameter. This spindle which is driven by a pall of hardened steel bevel gears having a ratio of 2.4 to 1 at a speed of 500 R.P.M. is mounted in two self-aligning radial ball bearings and a thrust bearing, the ba of which measure 1% in. lu diameter, s provided to take care of the end thrust Ball bearing ire used throughout the machine The hoist ttachment for handling heavy work pressure weight vhen the lighter work is being ground consists of a hand-operated chain hoist mounted on a trolley and swingi!

The output in October, according to the blast reports of THE IRON AGE, 26,591 tons, the largest ever The increase had been steady and progressive since the war started until July, this year, when there was a decided spurt. While the average for the first half of this year was 19,892 tons per month, the and October has been 24,749 tons per month. furnace was gross recorded. average for July, August, Septembe: This is three times the monthly average of 8280 tons per month in the five-year period 1910-1914.

It is also how the four the five-yeal interesting to note declined, In the 2OD6 imports have only tons per month or over 50 per cent less than that fo the first six months month. While exports last months the average has been when they were 5099 tons pe? have not been large recently, they are significant, as showing the shifting of the dependence of foreign countries, particularly Italy, from England to the United States for supplies of the alloy. An important fact regarding the October output is that more ferromanganese was made in electric fur naces than in any other month. The 1917 output of ferromanganese will be about 268,000 tons, if the November and December production equals the average for the last four months. This con- trasts with 221,532 tons in 1916. The output to Nov. 1 has been 218,348 tons or nearly equal to the 1916 pro- duction. Imports in 1917 will not exceed 45,000 tons at the present rate of decline.

The prime object in the design of this vise was to provide a tool that is particularly rigid in its construction and one that is very compact so that the work can be held close to the table, being made as low as possible without sacrificing strength. A machine finished flange is pro vided on the four edges, allowing the vise to be clamped in any position. It is pointed out that milling machine vises are often used in place of a jig or fixture and be come an efficient addition to the milling machine, espe cially when used in pairs, one vise being loaded or un loaded while the cutters are working on the piece or pieces to be milled in the other vise, and that the vise is adapted for this service by having the tongue slot on every face of the vise an exact distance from the solid jaw The jaws are of steel, 6 in and open 4% in., I wide and 1% in. deep and can be readily removed for occa sionally increasing the range or inserting special The ways are solid, giving the base greater strength and the construction of the block and gibs is such that they wipe the ways free of chips and foreign materia!

Many so- called luxuries are composed largely of imported terials and if such materials should be embraced in th list of those subject to license the future of the indus- tries in question would be fully committed to the tet mercies of the War Trade Board. Notwithstandir fact that a number of so-called luxuries are en in the President’s proclamation, it is understood they have not been included therein with a view to veloping the Government’s policy for the treatm non-essential industries, but for other reasons, anda th no attempt will be made by the War Trade Board regulate importations of non-essentials or of raw terials for their production until the Bureau of Manv- facturing Resources, about to be established b) the Council of National Defense, has had an opportunity & perfect its organization and make such investigation as are necessary to form a basis of future action.
