Reduction Of Vacuum by Artihcial

Raw work designed Joy DR.. Morton. Nhen

point. il was lowered by putting the tune
In an oven and heating II 10 200 or 0VV ue-

Pint the delay and trouble Of doing this

of heating the table IN its working position

For instance the operator begins WORK
with tube whose vacuum forces a SIX
inch enark TO pass between the discHars-
inc rods of the coil. This may not leave
him enough margin Ok capacity in his COIL
en- me turns off the current and carefuHy
heats the tube with the flame Of a spirit
Iann This must be done boldly ana yet
carefully. The flame should be ample ana
sv,aved across the bottom of the tube
never resting in one place, until at last
the entire tube has become evenly not
then the lamp is Withdrawn to distance
and the current turned on. II the sparks

heating must be continued.
Finauv there comes a moment when, up
on turning on the current, 1t passes

and then Y ray work may begin Inc
amateur will often have an exciting time
with his vacuum. once lowered he may
sometimes keep it low by using current
strength. which keeps his platinum re-

hot.
But at last point is reached when even
heating with a fame-so far as Is consist
emit with safety-faiIs to reduce the vac

must be sent to be re-eXhausted.
In using a spirit lamp one precaution
must be kept i'm mind: the alcohol will be
ignited If IT is brought near 10 the tube
while the current is passing and an eX-
nIoslon may occur. Again the vacuum
may he lowered in other ways In tubes
oeneciaIv constructed for this purpose.
Oro ~ these ways is that described by
prof Crookes many years ago. TO the
tube is affixed small extension tuoe CON
tanning chemical salt which upon pelhg
heated by fame from the outside throws
out more or less vapor.
or as devised by Or. Morton. an inside
carbon flament having outside electrodes
g r,ounted within the tube. Upon passing
current through the hlament heat is pro-
5uced vapor thrown out. and the vacuum
lowered. See Fig. 52a In this manner
t,ba may be worked for a LONG time and
the vacuum be adjusted according 10 CIR

1t will be interesting to note that car
bon in any form-as diamond or as coal
or graphite-is almost perfectly trans
parent to the X Ray, while lead is al
most totally impenetrable TO it.
One of the greatest difficulties which
will present itself to the eXperimenter is
the choice OF apparatus for the produc
ton Of X Ray effects. 1t must be con-
fessed that pioneers n this field Of re-
search have made none 700 explicit state
ments as to their precise methods of
operation.
Roughly speaking, there may be said
to be three general methods of opera
tons involving the use OF % influence
or static electrical machines; (2) !nduc-
jiOn coils, whose primary circuits are
supplied ether with continuous or al
ternating currents; (3) Tesla transform
ers utilizing osc..!atory electrical cur
rents.

ployed to practically "kill' the sparkling

readily determine how much to use when
he has a regular variable condenser &c
control by watching the spark. On The
whole, basing the opinion on practical
experience is almost impossible TO get
