OF USEFULNESS
Morning is Devoted to Hearing
and Debating Reports; Ban
quet Will End Convention

49,. Al ttlt llndl SeSSlOH OF the suSdl
mill engineers convention. held this
morning three important subjects
were discussed by the members. "
| The paper on Sugar Room Machin
/ cry" by II. Keeling SchOlefield
opened by saying that:
In following the tenets OF 'Scienti
fic Management or Efficiency Engin
eering,' as applied to any manufactur
ing business, al accurate knowledge
OF the expense attached to each opera
ton in The process becomes requisite
/ In an effort to evolve new mat
ter for consideration, we have there
fore adopted the somewhat neglected
1 standpoint OF costs. "a table was
given showing comparative costsJ
THE attainment of any degree OF
| precision was SO manifestly -impos-
sible. in view of the paueity Of segre,
gated records relative to the subject
that the committee was. only encour.
aged to proceed by consideration OF
the fact that newly broken ground is
necessarily rough" ....
The report then took up the Hersey
| driver, concerning which it said: Con
! sidering the matter apart from its
! financial aspect, we have noted a
| growing tendency to eliminate the
! Hersey dryer. We also learned of some
! instances where automatic scales
! have been discarded, the installation
at Waianae being case in point. The
reasons for such action are no doubt
| founded on experience" II.
In regard to the: Hersey dryer, Dr.
Norris said that he believed that the
| usefulness of the dryer was now past.
At one time it was necessary but 9TH
er machinery has come in and with
the refiners Directing seriously to
the grade of sugar sent from the Ha-
waiian islands other methods of dry
ing must be developed. .-.. -.
Objection to Hawaii Sugar ...>
The main objection OF the refiners
to Hawaiian sugar is the large amount
of dry molasses which sticks to the
crystals and IS extremely difficult to
remove. " ... -.
McCubbin asked if, by taking the
moisture out of the air before using
it to dry the sugar instead of simply
heating the air, the molasses would
not dry so hard on the crystals? Or,
in other words, using dry air at
lower temperature instead of hot air
for drying purposes. .... ~
In answer the general opinion was
that the heat had very little effect
towards making the molasses, but it
was pointed out by Chairman Kopke
4l,nN h. CT or
tention to this matter of dried mo-
lasses on the sugar as he believed
that in the future contracts will also
take into consideration the cleanliness
of the crystals.
1t was then pointed out that the
reason for the baked molasses was
simply that the moisture had been
removed. -. ..".. ~.
Martin had a method by which the
refiners might remove the molasses,
saying that the refiners only need to
let the sugar stand in the syrup mix
ture sufficiently long to loosen the mo-
lasses before applying 10 the .centri-
fugals. &..... -..*.. .-..... :...:..
Tests and Records Needed
The next paper was, Testing and
Recording instruments" and in TAX
ing up this subject, Kopke declared
that recording instruments were not
used sufficiently by the engineers and ,
that daily plotting charts should be
used by them all. Il have found that
the big interests are always ready to
install anything new when they can |
be clearly shown that it is to their
he said, and advise |
you all TO prepare figures showing the |
necessity of such instruments. =
r. r. Hind said that when old ma
chinery is sold the money could be
placed in fund to buy recording in
This scheme was heartily |
received by the engineers, and Kopkei
said that the instruments were so ne
cessary that If he was running the
scheme he would be sure to have plen-
ty of old machinery on hand. '->
The reports says: 49,"
1T seems TO be the opinion of all
those engineers who have any opinion
TO express on the subject, that record
ing instruments are an extremely good
thing to have, and all would like to in
stall them if they could get them, but
such, unfortunately, is not always the
case. -. Il
The utility of recording instruments
lies not alone in the fact that they
keep a record of operating conditions
at the different stations of the factory,
but in the moral effect on the man or
men whose work they record; the TACT
that an absolute check is being kept
on their work every minute of the
1ay tends to make them toe the mark.
In this connection, it is generally con,
ceded that the best point to place a
recording instrument is where the
man or men whose work it records
can see it.
THE most generally used instru-
Lents are the live steam and exhaust
steam recorders; several mills have II
.hese if they have nothing else. Next
n number come vacuum recorders
md temperature recorders on pans
md eYaporators. At the Hilo Sugar
70, S mill, they claim to have reduced
