Efficiency of abrasives in working glass. J a c q c t s W o l f . Class Ind., 13 [12), 189-92 (1932).--Most mechanical abrasive working of glass is done with sand of vary ing grain size and pumice stone of various degrees of fineness, and in special work, emery and silicon carbide are employed. Grindstones of three classes, rotating disks, natural stones, and artificial products, play a prominent part in the mechanical working of glass. The hardness of a grindstone depends on various factors, (1) the nature of the abrasive, (2) grain size, (3) bond resistance, (4) distance between the grains, and (5) pore size. Applied technique affecting the output of the grindstone is considered from the standpoints of (a) m atter to be treated, (5) kind of work, (e) method of working, (d) band and automatic operation, (e) speed of rotation, (/) fitting up, (g) the upkeep, and (h) the wear. A full discussion of these points is presented. E.J.V. Adhesion of glue and fused alumina abrasives. IV. Henry R. Power. Metal Cleaning & Finishing, 4 [11], 611-12 (1932).--Glue briquet tests for adhesiveness made on three types of abrasive, untreated, glossy type, and surface tenacity type, showed that the latter was superior both before and after exposure. This type of abrasive is also superior in capillarity tests. All three types are wet by liquid oil a t about the same rate. For P art II I see Ceram. Abs., 11 [3), 146 (1932). E.J.V.

When gases are reduced to the dew point of the vapor, the combination of the S (whether existing as SO, or SO,) will occur, forming a corrosive acid solution To avoid such corrosion heat the feedwater to a t least 100 *F. preferably 120 F with cast- iron economizers, and with steel. 130 to 140 "F. The decrease in the efficience of the h e a t exchange is less serious than occurrence of corrosion. E.P.R. Boring map for day and loam deposits. Anon.

The Kelley trap is a metal chamber designed to enclose the drill steel at the rock surface from which the dust is removed by an air stream wbicb discharges into a trap. The minimum rate of air flow necessary to keep the dust con centration at the breathing zone of the drill operator safe was investigated and found to be 60 cu. ft./nun. Check tests were run with the trap operating a t th a t speed in connec tion with two actual jobs, and satisfactory results were obtained. Static suction require- Tients for various rates of au* now were also determined. h FV , D" st hazard in rock products industry. Anon.
