The G &T Vibratory Ball Mill
“ Projected” Balls Increase Efficiency and Rapidity of Grinding . . .
This ball mill operates on a principle new to mills of this type. By suspension of the pot on springs and the use of an out-of-balance weight the axis of the mill sweeps out a cylindrical path causing “ gravity-assisted ’’ projection of the balls with increased efficiency and rapidity of grinding.
The mill has been successfully applied to such materials as tungsten ores, rutile, ilmenite, coal, coke, alumina, boiler scale, slags, etc. The closed pot makes it of value in moisture determinations, where other grinding appliances may be unsuitable.

Carbon is unique, it is heat resistant, it oxidises only at high temperatures, at which it retains its shape and strength;
it withstands thermal shock, and is not
‘ wetted' by molten metal.
It resists erosion, being self-lubricating,
having good wearing properties and a high resistance to corrosion by powerful chemicals.
Carbon can be worked into very intricate shapes and to a close degree o f accuracy as required fo r a great variety o f purposes.
Manufacturers having problems that may be solved by the use o f carbon are invited to discuss them ivith our engineers.

YOU KNOW 2
— that
many factories use three or four times as much steam as is really necessary.
— that
at least half o f this waste can easily be prevented.
The attention of all business princi
pals', is earnestly called to the 20- minute speaking film — “ Steam ” just released by the Ministry of Fuel
& Power. It shows with pictures, diagrams and figures, the principal causes of steam waste, how this waste can be avoided; the best ways to insulate; the use of trapping systems;
means of using low-pressure steam for process work; how to air vent steam heating apparatus; how to recover heat in condensate and flash steam.
IS S U E D B Y T H E M IN IS T R Y J
ARRANGE FOR YOUR STAFF TO SEE IT — NOW Write t0 the Secretary
o f the Regional F u el Efficiency Committee"to find out what arrangements are being made in your Region.
I f a M inistry o f Information van is visiting your works with other films, ask for the film
“ Steam ” to be shown. (Also — if there’s time — the accompanying film “ Boiler House Practice ’ T)
I f you have your own projector
(16

T h e solution proposed b y D r . C la y is th at o n ly one firm should m ake a n y g iven type of in stru m en t. H e b elieves, fo r ex am p le, th at o n ly a la rg e firm w o u ld be fin a n c ia lly able to u n d ertak e the m an u fa ctu re o f com p licated instrum ents b y m ass' p rod uction m ethods and that s m a lle r firm s should be a llo tte d the m ore sim p le instrum ents.

H e goes on to s a y : “ F o r the success of such a schem e it w o u ld seem th at at least three th in gs are neces

in stru m en ts, or le ctu re ap p aratu s, or m icroscopes— should form a group , and agree am ong them selves h o w the w o rk should be d ivid e d betw een them.
Se c o n d ly , each group should set up a s e llin g ag e n cy w h ich w o u ld accept the orders for the gro up and d iv id e them am ong the m em bers o f the group.
T h ir d ly , and of greatest im p o rtan ce, the design of the in stru m en ts m ust be good, necessitating the estab lish m en t of a com petent design and research staff. T h e kn o w led g e and experience of a ll the firm s in the gro up (an d outside it) should also be pooled fo r the benefit of a ll.
This" design staff w o u ld not o n ly design the a ctu a l instrum ents, but also assist in the design o f the tools and m ach in es re q u ired fo r theii: m a n u fa ctu re .” Fie believes, h o w ever, that a s till better result could be obtained b y com plete am alg a m a tio n of the firm s into groups such as a B r it is h S u r v e y in g In s tru m e n t C o m p an y, a B r it is h E le c t r ic a l In s tru m ent C o m p an y, and so on.
T h is set-up is also designed to p ro v id e greater, fa c ilitie s fo r research. T h e fact that we h av e been able to h o ld our own and com pete su cce ssfu lly in spite o f the im m ense research staffs of A m e ric a n and G e rm an firm s w ith w h ic h in the in s tru

B u t , says D r. C la y , so lo n g as we rem ain a la rg e .n u m b e r of sm all co m p etin g firm s, w ç cannot afford to support an adequate research staff.
T h e d ifficu lty of m a in ta in in g adequate sales rep resen tatio n abroad— and i f the representation is to be a d e q u a te the rep resen tatives must be te c h n ic a lly train ed — becomes in su p erab le fo r a c o l

R I T I S H scientists are as good as a n y in the ap p lie d field , and B ritis h in d u s tria lists are as w e ll able as an y others' to ap p reciate and to adopt ra p id ly ideas w h ic h m ay be new to them. T h is w as the contention of S i r E d w a r d A p p le to n , secretary to the D . S . I . R . and senior G o ve rn m en t p hysicist, in a p ap er presented to the R o y a l S o c ie ty o f A rts la st w eek, and it is a contention w ith w hich we h e a r tily agree.

W h a t we- w is h to insist on is the need fo r co n tin u a l rem inders of this sort.
