THE MONTHLY •-B13LL-ETT]T OF THE;WIRELESS INSTITUTE OF AUSTRALIA
APRIL 1967 TASMANIA^ DIVISION . TECHNICAL ARTICLE
THE TURBO ENCABULATOR By R. Itbeyewash.
UR1AF
Work has been proceeding in order -bo bring to perfection -the crudely- conc.eived
id-e'a of a machine -tha-b would, not only supply inverse reactive currents for use in
unilateral phase detractors but would also be capable of automatically synchronizing
cardinal grammeters. Such a machine is the "Tur'bo Encabulator".
The prototype machine had. a mounting plate of prefabula-ted amulite surrounded
by a malleable 'logarithmic casing in such a way that the two spurving bearings were
in a direo-b line with the pent ame-trie fan. The main winding was of the normal lo-bus-
(^-del-ba type placasd. in panendermic semi-Tsoloid. slots in the sta-fcor, every seventh
conductor being connected by a non reversible -fcremie pipe to -the (iifferential giirdle
spring on -the "up" end. of the grammeters.
Forty one manestically spaced, grouting brushes v/ere arranged to feed into the
slip-stream a mixture of high S value phenylhydrobensamine and 5^ remina-bive
tetryliodohexamine. Both of -these liquids have specific pericosities given by -the
formula P=2 5Cn where n is -the dia-fche-fcical ev-olu-be of retrograde temperature
phase disposition and c is Cholmondeley's annular grillage coefficient. Initially
n was measured, wi-fch the aid of a metaphor refrac-tive pilfrometer bu-b up to the present
da-fce, nothing has been found. -to equal -the •transcenden-tal hopper dadoscope for
accuracy. : :
Undoub-fced. ly the Turbo Encabula-fcor has now reached a very high level of technical
d. ev:elopmento It has been successfully used for operating nofer -trunnions. In addition
whenever a barescen-t-skar motion is required i-t rcay be employed in conjunction with
a drawn reciprocating dingle arm -to reduce sinusoidal depleneration. it has also been
used -to drive -the i-ri-bmd. 3 element widespaced directional dispersal. ring radiator
with grea-t; success.

VHP NOTES by Feed Back.
Unfortunately, as v/e still lack a certain amount of co-operation from members,
there is as usual, very little to report. I think we'will be pretty well informed
o f activities in the Launces-fcon area now, as -the Hooper Emporium has moved hor-fch,
and. if I caja-t sq ueeze mything out of him I give upill We would appreciate a few
notes from the North West area each month and this does not neccessarily. mean the
effort of pu-ting pen to paper. 7FB and 7LY are active on all -bmds from 3. 5mhz right
thru -to 53. 035 sn& shortly on 144 as well, just about every day. On -two Sundays out
of every three, we are on 3672 Kc during and after the call-back, and if we can not
be contac-fced at this time, o.r on this band a-b this time a sched could be arranged
•thru just abou-b any active Hobar-t s-fca-tion, as we are in contact with .-them all at
some time during each week. This of course applies to HF notes as well. With a little
GO- operation -from members, -the bulletin can be made as big and as informative as
you would wish, but-we are not mind readers,.. nor can we print a page of notes wi-fch-
out the necessary information Help us to help you S 73_g Mike, VE7FB.
