Services and Activities of the Missouri School of Mines and Metallurgy • • . By Wm. R. Chedsey, Director Fortunately it has b een poss ib le for m e to get in tou c h w ith several a lu mni gro ups, mainl y wit hin the S ta'te ; a lso in tOllch with g roup s of pa r ents of Ollr prese nt s tud ent body . To th ese g roup s I have been s tating the activities of t h e School, and in cidenta lly, making it know n th a t any con stru cti ve s ugges ti ons that might lead to the betterm ent of our program wo uld be welco m ed. Because I have not been ab le to r each a ll alumni, I th erefo re welcom e this oppo r tu ni ty to restate the general po in ts of our prog ram . Altho ugh our educational program is in general fairl y 'well ].;:no ll·n becau se of the success of most of our g raduates, it may be wdl to put on paper the facts that underlie the success of OU!' educationa l progTam. Founded in 1870, the course of stud y, wh il e rather nar row at first because of limited sc ientifi c material then developed , and sma ll staff, nevertheless 'w as a rigorous program of utilization of a\'ailable knowledge - scient ific, technical and economic-in the training of the st udents . The faculty have a.]ways been meticulous in requiring a full amou nt of wo rk and in a ,t ho roug-h coverage of their respective fie ld s .

For many years the Schoo l has probably r esemb led more nearly an industria l factory than th e average college in thaot from the t im e the wh istle blows at eight until noo n n early a ll students are busy and, likewise, from the one o'clock w histle until the end of \I-ork in the afternoon practically all st ud ents are busy . Time for study, reference r eacting, and the necessa'r y comp utations to straighten out poi n ts not clea rl y understood is crowded into the late r afte r noon and evening hours, thus m aking t h e work much

s im il a r to t hat of t h e emp loyee of indu s try w ho ta k es at least a ce r ta in a m ount of hi s work' hom e from t h e office to be do ne d uring t he e \~e nin g . \ i\T hil e th e earl y wo rk of the Sc hoo l was ·confi n ed t o civ il a nd minin g engin ee ring, th e o nly t wo clearl y re cognized. branches ex i st~ ing aot th e time th e Sc hoo l "vas fo unded. addit ion a l curri cul a have bee n put in as the s ubjects developed un til now t here is covered mining eng in ee ring, meta llurgica l engl11 ee n ng, petroleum enginee ring. mini ng geo logy, ceramic e ngineerin g, chemical en,· gineerin g, including petroleum refining, mechanical engin eering, ciyil engi n eering and electrica l engineering. Th ere is a lso maintained a cu rriculum with the minimum number of majors possib le in sc ien ce, but it is easily understood that thi s attracts few st udents where so much of the \\·o rk is predom inantly engineerl11g. Graduate work leading to :;\Iasters' degrees is offered in most lines mentioned , and ther e is poss ibility of work l'eading to th e doctorate in ce rta i n lines. The Doctor's degree is given by the u nivers ity of Mi sso uri, of which the Schoo l of Mine s and :M etallurgy is a division, although separated geogral)hically. Eve ry educational in s titution nowaday s knows the de sirabili ty, or a lmo s t eve n the necess ity, or a certa in amount of research and inve st igat ional work being carri ed on s imultaneously with its instructional activities, and the Schoo l of Mines is not a'n exception. Much of the Sc hool' s research act ivit y cen ters about OUf cooperative agreem.ent w ith th e U . S . Bureau of Mines Exp e rim en t Station situat ed on OUf campu s. There is cons id erable add it ional r esearch wo rk , holV-

eve r, as p a r t-t im e act ivi ti es of our teac hing s taff, practica·ll y all depar t m e n ts ha v i ng so m e projec ts b ein g- ca rri ed on . The State Min ing Expe rim ent Sta ti on is at p resen t a lm ost a sk eleto ni zed organizat ion, for du ring t h e depressio n yea rs fund s have been in adeq uate to s upp ort the wo rk compa rab le to the way in 'w hi ch it used to be suppo rted by biennia l appropria t ions specifica lly for the Expe ri ment Station of 50,000 ove r seve ra~ biennia . It is the natu ra l expectation that this work w ill be expandetl again as rapidly as fund s can be obtained to support it, for th e act il'itie s of the Station and of our teaching staff in resea rch line s frequently cont ribu te va luable economic res ults to the mine ra l indu str ies of Missouri. In s ub sta ntiation of this it n eed only be recal led that resea'rch es leading to mineral recove ry and low er costs are estimated conservatively by outside source s to have saved the Tri-State lead-zinc regi on at least $5 .000 ,000 a yea r. Incidentally, $:5 .000,000 is very clo se to the total of State appropriations from the founding of the School in 1870 until 192-! when these r esea rch es were applied with s uch say in gs in the Joplin region.

Metallurgical Engineering and Ore Dressing By Max Bolotsky

New eq uipm ent recently purc hased and insta ll ed by the Meta llurgy Department find s alm ost eve ry cou rse benefited. Apparatus fo r spect rograp hic a na lys is. la rgely t hrough the in dividual effo rts of Dr. Cook e, who teaches th is su bj ect as part of t he meta llurgy curri cu lum , has bee n brought up to a hi gh st a ndard. In a ddition th e D epa rtment has a dd ed a resea rch type Bausch a nd Lomb meta llograp hi c came ra, two metallurgica l mi scroscopes, a reco rding poten tiometer, a roasting furn ace, a Beck ma n hy droge n ion ind icator, a Rockwe ll ha rdness tester, and a I-Iayes co ntroled a tm osphere hea t t rea ting furn ace. A savi ng of betwee n $800 a nd $1000 was effected by .Dr. Cooke workin g in cooperation with Professo r A. V. Kilpat ri ck of the Mechan ical E nginee ring departme n t in enl a rging th e spectrograph ic appa ra tu s. Betwee n $600 a nd $700 was conse rved in bui ldin g a ph otoelec tri c micro-de nsitomete r a nd spect rum comparator. This is u sed for meas urin g qualitatively a nd qu a nti tatively spec tra on films a nd plates. It was design ed by Dr. Cooke a nd built in Mec han ica l H :dl by Professor Kilpatr ick. Old eq uipm ent from X- ray a pp a ra tu s that for merl y belonged to th e A thletic Assoc iat ion was utili zed by Dr. Cooke in fabr icating by himself app a ratus needed for produ cing a spa rk in spa rk spec trum a nal ys is. The catalog va lu e of thi s se t-up would be betwee n $200 a nd $3 00. It cos t Dr. Cooke Ju st sixty-fi ve ce nts to co nstru ct! In a ddi tion a new la bora tory t able and a new spec trosco pic cover we re a dd ed. The la tter enables th e spectrosco pe to be operated in a we ll lighted room instea d of in a dark room as prev iously. Supp lemen tary eq uipm ent has a lso been purch ase d by th e State M ining Expe rim ent Station. Th ese add iti ons w ill be ava ilab le for student use. They include a n arc a nd spark stand, w hich ca n be operated in th e open; a quartz co nd ensing sys tem a nd a dju stabl e rotating secto r to vary th e amount of light adm itted to th e spec trosco pe; a nd a quartz-me rcu ry-ca dmium vapor

lamp. Thi s appa ratus will be used in producing a n arc spectrulll and in stand a rdi zing photograp hi c film. T he latte r ope rati on is esse n t ial for q ua n t itati ve spect rography. T he State Experiment Stat ion has also purcha sed a G:Jert ner microdensito merer whi ch ca n be u sed for mea su rin g spec tra qu alitat ive ly onl y. Jn so me respec ts it is eas ier to ope ra te th an th e ot her new microdensitomete r, but it is not a reco rdin g instrument a nd w ill se r ve as a n ex tra instrum ent for student use. T he other new eq uipm ent of th e Metalurgy Department has bee n inst all ed in seve ral labo rato ri es. The ph ys ica 1 testi ng la bora tory has been furn ished with seve ral new in strument desks a nd rea rra nged . The new Rockwell ha rdne ss tes ter has bee n place d here. The new recordin g potentiometer a nd th e old R ockwell h a rdn ess tester ha ve bee n place d in th e hea t treating la borato ry. This potentiometer is a two-poi n t reco rd er a nd records th e t emp era ture of the fu rnace as we ll as the difference in temperature betwee n the furn ace a nd th e m etal bein g heat t reated. In th is la bora tory is a lso a dil ato mete r whi ch has bee n rece ntl y set up. T hi s instrument is u sed to dete rmin e the coeffi cient of ex pa nsion, tra nsfo rm ation points, grain size, a nd other prope rti es of m eta ls a nd a lloys.

CERAMIC ENGINEERING Th e Ceram ic D epa r tment has been fo rtun ate in securing t he following new equ ipm ent during t he past yea r:

(1) R epl ace ment of the hi gh temperature test ki ln w hi ch h ad been turned oye r to th e department by the Burea u of M ines in 1926. The new k iln is sli ghtl y large r and is equ ipped w ith Ma hr oil burners and an oversize blower so that a tempe rature of 1600 Â° C. is easil y atta ined. It is eq ui pped with a new rad iation pyrometer whi ch is attac hed to a record ing potentiomete r. A CO, m ete r h as a lso been in sta ll ed, so the k iln firin g m ay be done at m ax imum effi ciency. (2) A reco rdin g electrop hotometer IS in th e process of co nst ru ction. Some of th e pa rts for thi s appa rtu s must be imported from Germany, and h ave bee n delayed . The in st rum ent wil l be used for mea suring th e intensity of the lin es on X- ray film s, thus elimina tin g as fa r as poss ible the hum an element in m aki ng X -ray determin ation s. (3) A new gas m ete r has ben added to the ph ysica l laboratory equipm ent to measure the permeabil ity of ceramic products.

(-t) A Gardner m ob ilometer for the mea surement of v iscosity of cl ay a nd ename l slip s h:ts a lso bee n added to th e ph ys ical la boratory equipm ent. (5) A de-airing auger m ac hin e h as bee n sec ured at a ve ry reaso nabl e pnce. It removes th e a ir from clay as it IS ex truding it to form tub es a nd ba rs. The ex perim ents wit h de-a iring have shown th a t by t he remov al of a ir in th e formin g process the pl as tic strength of the cl ay p roduct is g rea t ly increased. For insta nce, a brick co lumn 4 fe e t long, w hen lifted by the end , wou ld brea k ofF a t the d ie; but after de-a iring the sa me clay, It is possib le to suspend a col umn 28 fe e t long without break ing it.

The roas ting furnac e, w hi ch wa s design ed by th e D epartm ent, has been inst a ll ed in th e elec trom eta ll urgy la borato ry. It is a reve rb eratory ty pe furn ace usin g globar rods as th e heating elements a nd was specially bui lt acco rdin g to spec ifi ca ti ons of t he D epartment. Th e o th er equipm ent added to th e la bora tory a re the hea t treating controlled a tm os phere Ha yes furna ce, th e old reco rdin g potenti omete r, a nd the Beckm a n hyd rogren ion indicator. Th e latter in strum ent will be used in Rota tion as well as elec trometa ll urgy.

A new Bausch a nd L omb R esea rch T y pe M'icrosco pe equipp ed for bri gh t a nd da rk fi eld illumin a ti on and for polarize d li ght wi ll be deli vered thi s sp nn g.

A good many other sma ll pieces of equipm ent, such as sta nd a rd testing sc ree ns, etc., have been a dd ed to make t he fac iliti es of th e labo rato ri es more co mpl ete.
