British palladium chloride method, Hopcallte iodic*tor. iodise pestsxide, and pyre- taasic arid. The results iadirated that, if the time factor It considered, the Hopcslite isdicatcr is the best, although la concentrations of 0.01 to 0.1% CO, the British palladium chloride method rave rood result*. The Hoola- mite detector was considered the least satisfactory of all. Details of test procedures an given. B.C.R. Coatral tad esllacdoa of iadustrial dast: OX E. D. PowtM.

H.E.S. Dust disease*. Anon. CXtm. Eng.

Dust problems is bussing blast-fursaes gas under steam boilers. A. R. Mtrwroin. Combustion. 13 (11) 35-37 (1942).--A survey of a number of installations indicates that dirty gas, when not supplemented itb other fuels, is satisfactory for burning under boiler*, ma with re fractory setting). When supplementary fuel, such as oil or pulverized coal, is employed, the higher resulting gas temperature may cause the dust to fuse and produce slagging on the beating surfaces. In such cases, senega- tioa ci the burning coses it dessnble. The cost of hours' cleaning, however, is usually much less than that at sub jecting the gu to primary washing, and appears to justify the use of duty gas. H.E.S. Grate temperature) a measure of ignition penetration. Waltsx H. Wood. Combustion. 13 14) 31-32 (1942).-- When the rate of ignition penetration of a notes fuel bed is known, it is puwibla to apply air for combustion most ef fectively in each son*. A convenient means of asestain ing the ignition penetration is through tht measurement of grate temperatures by means of thermocouples. Direc tions for their installation and use are given. H.E.S.

He points out the things that are and ve not patentable and the various fac tors that govern patentability. Commonplace examples are cited, and each point is verified by reference to report* of higher court decisions as listed in the bibliography. H.E.S. Importance of invention to the nation- H. A.

England and colonial Inven tions. economic justification for patents, and patent re wards. T. attribute) America's great industrial and eco nomic development to her unique patent system. E.D.M.

No incidence rates of value could b obtaii but mortality tabulation) from these counties sbo- iower rates than those occurring in the U. S. a* a wb In the Gogebic range in Gogebic County. Mieh.. ant Iron County, Wi*., mortality rates for uadtggro> vorhen are practically the same aa for surface worker the same age. In the iron-ore mines of the Upper Fe aula. 20 yean of underground work were required silicotic nodules to beiiau* largo enough to be seen et> X-ray film, susd miners with silicosis who eontrse pneumonia did is well is those with no silicosis. Wori with advanced tdicotis often recovered from the pc media without any sgwtific treatment. The IB pc menu deaths occurring among 6000 employe* of mining companies' during a 4-year period would giv yearly mortality of 65 per 100.000, which is the uni that for policemen, who have no silicosis. P. condu that scute lobar pneumonia is an infectious, commtisiet disease but not an industrial disease. K.p Low draft losa Sot-dust calleetora at Coaairs Cr powerhouse. H. E. Macons**.
