I SILICOSIS DISCUSSED AT TENTH ANNUAL EASTERN SAFETY CONFERENCE T H C E on f T er e e n n th ce Annual Eastern -was held Jan. 18 Safety at the Robert T reat Hotel, Newark, N. J., with m orning and afternoon meetings, divided into a number of individual sessions. These were as follows: Occupational Dis ease and Compensation Session, General Manufacturing, Chemical, ABC, Commer cial Vehicle, Public Utilities, Small Plant. "Asse," M anagement and Accident P re vention Sessions. The first noted, Occupational Disease and Compensation Session, had silicosis as the primary topic of discussion, and the industrial hazards of this disease were fully analyzed by different speakers. The Hon. John Roach, Deputy Commissioner of Labor, New Jersey Department of La bor, acted as chairman. T he first subject was "W hat are the principal toxic substances that menace the health of workers such as fumes, gases, etc?" This was delivered by Dr. H enry H . Kessler, Medical Director, Newark Rehabilitation Clinic, with a discussion following by Dr. Leonard Greenburg, sanitary engineer, United States Public H ealth Service, Yale School of Medicine, New H aven, Conn., and Dr. A lbert S. Gray, chief, division, of occupational dis ease, Connecticut State Department of Health, H artford, Conn. Silicosis was the next topic up for dis cussion, termed "Dust Diseases that M enace the Lungs of W orkers." This was presented by Dr. William J. McCon nell, assistant medical director, M etropoli tan Life Insurance Co., New York, who brought out different points of the dis ease, the effect of dust inhalation by workers, and resulting reactions. The spread of the disease in late years was Middle and West Tennessee are promising centers of future expansion of the ceramic industries. Too long, the manufacturing possibilities of these areas have been neglected by ceramic interests. Expansion in both clay-mining and clay-products manu facture is justifiable. Trade condi tions will dictate the trend of new operations and the degree of expan sion of present industries, but certainly the ceramic horizon in both areas is bright with promise of increased ac tivities. Erratum The map printed with first installment of this paper last month carried an erroneous legend. Indication for heavy clay products plants was that for pottery locations, and similarly, pottery indications were those of heavy clay products plants. noted, and the menace to various lines of industry, including the ceramic field. Following, Henry F. Smyth, M.D., L aboratory of H ygiene, U niversity of Pennsylvania, School of Medicine, led a discussion on the subject, outlining fa miliar phases which had to do both with " workers and plants, as well as the cur rent efforts to eliminate this hazard in every possible way through the installa tion of modern equipment for dust elimi nation. The third speaker on the subject was Louis DeBlois, consulting engineer, New York. T he final subject of this session was "Determining the Medico-Legal Aspect of Occupational Diseases," divided into three main considerations, (a) "Shall we have a state board of doctors to pass on them ?" (b) "Shall its determ ination be absolute so far as our compensation courts are concerned?" (c) "Shall com pensation courts pass on any questions other than those of a strictly legal na ture?" This was discussed quite ex haustively by a num ber of speakers, in cluding G. H. Gehrmann, M.D., medical director, E. I. duPont deNem ours & Co., Wilmington, Del.; Stephen Lorenz, spe cial counsel, Departm ent of Labor, and F. S. Kellogg, counselor at law, Jersey City. Th other sessions noted at the begin ning of this comment all had to do with safety in industry, and the constant work and efforts that should and must be de voted to this feature of industrial activity. In the different meetings all primary and secondary hazards were discussed, deal ing with general plant procedure, mate rial handling, plant lighting and the like. Exhibitors A number of manufacturers of safety devices and equipment had exhibits in connection with the meeting. The m ajor ity of these covered respirators and other apparatus designed to be worn by w ork ers engaged in hazardous occupations. These included: Pulmosan Safety Equip m ent Corporation, American O ptical Co., B. F. Goodrich Rubber Co., Standard, Safety Equipment Co., W alter Kidde & Co., Shepherd Safety Shoe Corporation, Hynson, W estcott & Dunning, Inc., Le high Safety Shoe Co., Mine Safety A p pliance Co., American L aF rance & Foamite Industries, Inc., Safety First Shoe Co., and International Shoe Co. Investigation of Fillers For Brick Roads The Engineering Experiment Station, Ohio State University, Columbus, Ohio, in cooperation with the Metropolitan Paving Brick Co., Canton, Ohio, is conducting an investigation of fillers for brick in road construction, under the direction of Dr. W. C. Rueckel. While it is proposed to investi gate other collateral paving brick problems, the immediate research is for the elimina tion of exuding of filler from joints in brick roads. Recent tests indicate that removal of excess filler material from the surface of the road is practical. This' procedure leaves a flush joint in the paving and pro duces a road with excellent anti-skid char acteristics. The filler in the joint, how ever, in man veases exudes when exposed to hot weather and becomes spread over a large portion of the road surface by traffic. Thus, as indicated, the investigation has for its main purpose the development of filler materials which will not exude from the joint when exposed to hot weather. A de termination of the physical properties of such materials will be made so that speci fications may be drawn to include their use in brick road construction. Porcelain Enaniel Parade at 1934 Century of Progress Plans are under way for the "second edi tion" of the Porcelain Enamel Parade at the 1934 Century of Progress Exposition, Chicago next summer. The Porcelain En amel Institute, again sponsoring this coope rative exhibit announces that the response to its solicitation among manufacturers of porcelain enameled products and others in terested in the industry's progress was most encouraging. It has not as yet been deter mined what additions will be made to the new exhibit but an improved and still more effective display is assured. The theme will be the same--the red, white and blue porce lain enameled soldiers and signs again identify each exhibitor's space. It is planned to enlarge the educational exhibit and add new features to make it more pertinent and interesting. It is now pro posed to develop a supplementary educa tional exhibit to show physical tests and other demonstrations of porcelain enameled products. The fact that nearly 60,000 ash trays were made and sold last year indi cates the popularity of this feature and it will be continued, possibly with the addition of some other type souvenir. University of Illinois Adds Administrative Courses The Department of Ceramic Engineering, University of Illinois, Urbana, has added an Administration Option to its regular ceramic engineering curriculum. This ex pansion follows a number oi requests from the industry and students, indicating the need for men in the industry both with com mercial and technical training. The option begins with the third year of University work, and includes such topics as Eco nomics, Industrial Organization and Man agement, Business Letter Writing, Market ing, Money Credit and Banking, Salesman ship, Accounting, Management in Manufac ture, Personnel Administration, Corpora tion Management and Marketing Policies. 43 May, 1935 CERAMIC Established 1921 Volume 25. Number 5 The Ceramic Engineer as a Salesman JUNE is approaching rapidly and w ith it w ill come the usual group of graduates from the dif ferent ceramic institutions. Some of them , for tunately, have secured positions, w hile others are iving a little concern regarding im m ediate future occupation. Laboratories and other similar sources of consum ption for the technical graduate are quite well supplied w ith their quotas, and it is only here and there that a vacancy exists. Companies em ploying qualified ceramic graduates, likewise, do not offer much encouragement when it conies to increases in the present staff. It is a case of concerted effort that faces the ceramist or ceramic engineer in the early months to come if he wishes to obtain em ploym ent. T he road frequently is a hard one and especially so in such tim es as these. If the graduate has sufficient ability to sell his own services, as h e m ust do to win a desirable position, lie might w ell go a step further and if in any sense a salesman, seek to apply his technical and selling ability collectively. In other words, start out for a position where such qualifications are much sought and much in demand. A good salesm an in any lin e-- a really good one--rarely wants a job. And this can be said w ith em phasis w hen it comes to the en gineering salesman or the ceramic technical salesman, as the term m ay b e applied. Show a com pany that be can m ake good in sellin g is hut another way to say that the *35 graduate not only has a job but a future. There are a number of outstanding examples of ceramic engineers who have m ade a high mark in the selling field, either em ployed by a com pany or 111 business for them selves. The foregoing comment ls inspired by a recent talk w ith one of these men, v'bo signalizes the broad and exceptional oppor tunities that are prevalent for the ceramic graduate lo apply h is technical know ledge in selling ceramic products. Such a know ledge is rather definitely re quired and it presents an excellent basis for the be guiling of a ceramic career. Let the June ceramic graduate give serious thought to this; let him bend his efforts in channels that are ,lt quite so com petitive as some of the m ore usual fields open to the young fellow entering the business world and possibly not quite so easy. Just as every graduate is not fitted for research or the laboratory so all of those securing their degrees are not suited to the selling field. It takes a natural ability or at least definite inclination; if this exists, its advantage should be utilized. Some of the finest positions in the selling field in ceramics, as w ell as in other lines of industry, have been created by the men seeking them. Show a con cern where technical knowledge plus selling ability can be used to company profit and the way usually is open to one who has real faith in his own ability. If he lacks this, then the fundam ental requisite is missing and he is only wasting time. Ceramic products need ceramic salesmen; the col lege graduate should use his technical training in a way that w ill mold his immediate future. The op portunity is his. The Gulf Coast-- And Its Ceramic Artists IN the last issue of C er a m ic A cf., and continued in the present number, articles of unusual inter est have been presented on potteries of the Gulf Coast by Prof. Paul E. Cox, director, Department of Ceramic Engineering, Iowa State College, Ames. Prof. Cox spent the larger part of last summer in the district of which he writes, and gives an intimate first-hand picture of Gulf Coast ceramics of decided merit. Here is a territory of which little previously has been divulged of ceramic accomplishments. A perusal of the articles gives a most interesting insight of art pottery developments in the Louisiana and Mississippi areas. The character studies of some of the pioneer ceramic craftsmen of that region point out conclusively that the potter and his art has been existing and thriving here beyond any monetary mo tives. These men and women have loved the game; they have been and are making original pottery that has characteristics all its own. It is a life 's work and they are giving their life to the beautiful through inspiration and affection. In this series of articles, with another installment to appear next month, Prof. Cox is to be commended for his contribution to cera mic literature on a heretofore neglected subject. 149 . ,, ,,as for fuel.

Each kiln holds from 2000 to 2200 careers, with 90 to 100 nail knobs packed in a sagger. The saggers are not wadded. Firing this kiln charge usually requires about 130,000 cu. ft. of gas. Each kiln unit is 10 ft. inside diameter, and 11% ft- high to springline of arch. The firing equipment consists of triple nozzle gas burners operating through six firing holes and flues, equi-spaced about the circumference of the kiln. These fire against bag w'alls, the height of which together -with the size of the flues, is controlled by the varying con ditions of draft, atmosphere, kiln de den. and associated factors. The hot products of combustion rise up around the sides of the kiln and are deflected down by the crown and through the kiln charge, exhaust is carried out by natural draft through ports in the kiln hearth and out through flues running up the kiln wall to a stack. The crown separates this stack from the rest of the kiln; there are rings of sleet holes as well as a center hole in the crown, kept closed with brick dampers. Some of the ascending hot products of combustion are passed here as part of the heat and atmosphere control schedule of the kiln. A 5-in. gas manifold encircles the kiln. There is a 1-in. take-off for each group f the burners. The kiln wall is com posed of 9-in. highgrade fire brick, 4% in. of insulating r efr act or y, and 9 in. of common brick.

Silicosis Made Compensable Disease in North Carolina The North Carolina State Legislature recently has passed a new law placing 'dicosis and asbestosis in the class of occupational diseases, compensable un.cr the Workmen's Compensation Act the State, adopted in 1929. These two diseases are included in a group of specific occupational hazards to be -t-eiJed to the State Law under an mu-udment. Industries which are sub--;t to the hazard of silicosis will be -csiguated by the Industrial Commis>u,n, and employers in these industries -t'ise d accordingly. Medical examina:n by a competent board will be re quired of all present and prospective employees in the designated industries. Co mpens at i on will he paid only in case of actual disablement or death. A hu mane feature is embraced in the new law, p r u\ idi ng limited compensation for those found to be afflicted with silicosis hut not actually disabled, until they might find wor k in noil-hazardous pur suits. A pertinent and logical tcaturc of tin- Act is that it applies only to e x posures after the effective date of the law, eliminating the troublesome con siderations of priority of ailment that have hampered enactment of similar leg islation in the past. Compensation in sur ance p r emi um rates will now he e x pected to take into account the degree of protection offered by an employer, making for real protection and ultimate elimination of the silicosis hazard. California State Legislature.

(4) No compensation for death from The bill provides for the establishment of an elective system of compensation for occupational diseases known as silicosis and asbestosis, and regulates procedure for the determination of liability and compensa tion thereunder, supplementing Chapter 15 of Title 34 of the Revised Statutes. The provisions are as follows: (1) Employer and employe may elect to accept or not to accept the provisions of this act. When accepted, every such em ploye who, in the regular course of his em ployment, suffers total disability or death as the result of silicosis or asbestosis, as hereinafter defined, shall be entitled to workmen's compensation, as provided. ( 2 ) Definitions: (a) "Silicosis" means disease of the lungs, due to breathing air containing silicon dioxide (SiO,.) dust, characterized anatomically by generalized fibrotic changes in the lungs, with a de velopment of miliary nodulation, demon strable by X-ray examination or by au topsy, resulting from any process or occu pation involving the inhalation of silicon dioxide (SiO-.) dust. (b) "Asbestosis" means a disease of the lungs, due to breath ing air containing asbestos dust, character ized anatomically by generalized fibrotic changes in the lungs, demonstrable by Xray examination or by autopsy, resulting from any process or occupation involving the inhalation of asbestos dust, (c) the word "disability" means the state of an employe's being actually incapacitated, be cause of silicosis or asbestosis, from per forming his work in the last occupation in which he was iniuriously exposed to the hazards of such disease. The word "dis ablement" means the event of being so in capacitated. (3) Where an employe suffers from silicosis or asbestosis as defined in Section 2 of this act, and is thereby totally disabled, or dies as a result of such disease, and the diease was due to the nature of said last occupation, the employe, or in case of death, his dependents shall, except as other wise provided, be entitled to compensa tion in the amount and payable in the manner provided in article two of Chapter 15 of Title 34 of the Revised Statutes. silicosis or asbestosis shall be payable to any person whose relationship to the de ceased which, under the provisions of this act would give a right to compensation, arose subsequent to the beginning of the first compensable disability, as herein de fined, save only to afterborn children. Where compensation is payable for sili cosis or asbestosis under this act, the em ployer in whose employment the employe was last injuriously exposed to the hazards of such disease for 60 days or more, and the insurance carrier, if any, on the risk when such employe was last so exposed under such employer, shall alone be li able therefor; the amount of the compen asation shall be based upon the wages as defined in Section 34:15A 7 of the Revised Statutes. An employer shall not be liable for any compensation for siliosis or asbestosis un less such disease shall be due to the na ture of an employment in which the haz ards of such disease actually exist and are characteristic of and peculiar to the trade, occupation, process or employment, and was actually incurred in his employment, and unless total disability or death results within three years after the last injurious exposure to such disease in such employ ment; or, in case of death, unless death follows continuous total disability, as here in defined, from such disease, commencing within the period above limited, for which compensation has been paid or awarded or claim filed as provided in this act, and results within seven years after such last exposure. . (5) In the absence of conclusive evi dence in favor of the claim, disability or death shall be presumed in fact not to be due to the nature of any occupation with in the provisions of Section 2 of this act, unless during the 10 years immediately preceding the date of disablement the em ploye has been exposed to the inhalation of silicon dioxide (SiO-) dust or asbes tos dust, as the case may be, over a period of not less than five years, one year of which shall have been in this State, under a contract of employment existing in this orate; provided, however, that if the em ploye shall have been employed by the Silicosis Bill same employer during the whole of such five-year period, his right to compensation against such employer shall not be affected by the fact that he had been employed dur ing any part of such period outside of this State.
