No ' Ceramic industry in Sudeten Germany. A non Keram Rundichou, 46 [44 | 515-18 (1938) --Tbs stats of ths ce ramic industry in Sudetenlind and its organization, out put, and raw maisnals at ths tims of its return to Ger many ars discussed. M.V C Comparison of method* for the determination of CO. F H Goldman and A D B slandt -4mer. Jour. Pub Health, 32 (5) 475-80 (1942).--The following methods for determining CO were compared: Hoolamite detector, palladium chloride ampoules, British palladium chloride method. HopcaUte indicator, iodine pentoxide, and pyro- tannic acid. The results indicated that, if the lime factor is considered, the Hopcalite indicator is the best, although in concentrations of 0.01 to 0.1% CO, the British palladium chloride method gave good results The Hoola mite detector was considered the least satisfactory of all Details of test procedures are given. BCR Control and collection of industrial dust: III. E. D. P owers Rock Products, 43 |9) 48-19, 51 (1942).-- Recent developments in high-efficiency cyclones and the selection of the proper type are discussed. For Parts I and II see Ceram Abs., 21 [8] 175 (1942). BCR. Correct power-station lubrication not baled on rule* of thumb. H oward Cooper Combustion, 13 [7] 30-32 (1942).--C reviews the principles underlying the lubrica tion of power-plant equipment and the various conditions that must be investigated by the lubrication engineer be fore prescribing the correct oil for the individual case H.E S Dust disease*. Anon Chcm Eni if dimn[ Rex., 34 [405 ] 275-77 (1942) --The most frequent types of dust diseases, chemical and physical characteristics of dusts, and means of dust control are considered. BCR. Dust problems in burning blast-furnace gaa under tteazn boilers. A. R. M umpord. Combustion, 13 [11] 35-37 (1942).--A survey of a number of installations indicates that dirty gas. when not supplemented with other fuels, is satisfactory for burning under boilers, even with re fractory settings When supplementary fuei, such as oil or pulverized coal, is employed, the higher resulting gas temperature may cause the dust to fuse and produce slagging on the heating surfaces. In such cases, segrega tion of the burning zones is desirable The cost of boiler cleaning, however, is usually much less lhan that of sub jecting the gas to primary washing and appears to justify the use of dirty gas. H.E.S. Grate temperatures a measure of ignition penetration. Walter H. Wood. Combustion, 13 [8] 31-32 (1942).-- When the rate al ignition penetration of a stolcer fuel bed is known, it is possible to apply air for combustion most ef fectively in each zone. A convenient means of ascertain ing the ignition penetration is through the measurement of gTate temperatures by means of thermocouples. Direc tions for their installation and use are given. H.E.S Guide for inventors. L. T. Parker. Combustion, 13 [10] 47-49 (1942).-- P. presents facts for engineers who contemplate applying for a patent. He points out the things that are and are not patentable and the various fac tors that govern patentability. Commonplace examples are cited, and each point is verified by reference to reports of higher court decisions as listed in the bibliography. H.E.S. Importance of invention to the nation. H. A. T oulsiin, Jr Chcm Industries, 51 [G] 695-99 (1942).--The Ameri can and European patent systems arc compared. The following points are discussed: economic importance of inventions, economics of im .n tion s, results of inventions, public policy behind patents, England and colonial inven tions, economic justification for pitents, and patent re wards T attributes America's great industrial and eco nomic development to her unique patent system. E .D .M . Increased ateel-mill production by protective lubrication. A.non Lubrication, 28 |7 ] 73-34 (1942).-- The Texas Co,, New York, N' V , has enhar. rd the usefulness and met the demands of the modem steel mill's production line bv p u- vnding protective lubrication. Factors which promcie fective maintenance and methods of extending the use u life of steel-production machinery are discussed H E S la acute lobar pneumonia a complication of ailicoa s D C P ierront Jour. Ind H yt if Tozicol . 24, 2 3 i- r - (Oct , 1942) --P investigated the incidence and rr.or-al rate of acute lobar pneumonia in the northern count e: of Michigan and Wisconsin where iron mining is the ch-J industry. No incidence rates of value could be obtain-d but mortality tabulations from these counties showee lower rates than those occurring in the U S as a whc.c In the Gogebic range in Gogebic County. Mich . and u Iron County, W'is . mortality rates for underground workers are practically the same as for surface workers o' the same age. In the iron-ore mines of the Upper Per c sula, 20 years of underground work were required o silicotic nodules to become large enough to be seen cn az X-ray film, and miners wuh silicosis ho c o n tr a c t pneumonia did as well as those with no silicosis V c -g -r with advanced silicosis often recovered from the pr. u monia without any specific treatment. The 18 pr.-u moma deaths occurring among 6000 employees of z* raxing companies during a 4-year period *ould g-.w . yearly mortality of 68 per 100.000, which is the sarr a that for policemen, who have no siiicosis P cone j: c that acute lobaj pneumonia is an infectious, commumca disease but not ao industrial disease K ?
