measurement or quality. Is detected

Rochester-and Rochester IL renown-
ed throughout the world for being
the home Of quality manufacture
Is more care taken to see that the
finished product is perfect.
Where Industry Meets Science.
The Ritter company makes an ex-
cellent air-compressor. The COM
pressor pumps. which draw in the air
through screening cotton chambers,
are operated for eight hours after
final assembly TO grind in the piston
rings and bearings so they work
perfectly. The compressor is equip
ped with an enameled-metal or a
glass hood. Many dentists prefer
the latter as IL makes the compress
or an attractive piece Of equipment
for the Office. The compressor is
controlled by an automatic switch
which never lets the pressure In the
tank go below forty-fve pounds.
The little hot-air syringe in the unit
system is alone made up Of sixty
different parts. The air is heated as
il comes from the compressor by
passing over hot electric plates.
The Ritter dental chair Is a superb
product whose every part is beauti-
fully finished. Roomy. comfortable
for both patient and operator. easily
adapted TO various positions, it Is the
leader in its field. Its arms may be
dropped entirely or to any desired
position. even to form seat for the
operator. The operator may even
adjust the back and arms 80 that n
small child fits snugly into IL. It can
be raised. tilted and otherwise ad-
justed in all its parts without the
least exertion by the operator. More
than thirteen hundred carefully exc
cuted operations, including the up
holstering. are required to manufac-
ture this magnificent dental chair.
Each finished chair Is tested in a
sound-proof room to see that il can
be operated with no noise.
The Ritter Company manufactures
dental X-ray unit for the taking
Of photographs Of the teeth. It is
sturdy. compact, easily operated and
safe for both operator and patient.
1t is the result Of years Of study by
the engineers Of the company Of the
progress Of photography with the idea
Of ultimately being able to offer the
dental profession an X-ray unit which
would be as perfect rs scientific re-
search and electrical and mechanical
excellence could make II. More
than twelve hundred operations are
required at the plant in the pro-
duction Of one Of these units. A
little primary transformer is part Of
the unit,enabling the operator to
step-up city current when il enters
the machines with less current than
10 volts. Forty-five thousand volts
are used in X-rays, by this machine.
An automatic time switch shuts of
the X-raying at the end Of the inter-
val desired.
Clinic For Research Work.
The company has established a
dental clinic which will do extensive
research work as well as demonstrate
to prospective purchasers Of Ritter
equipment the best methods Of dem
tistry. The company maintains
branch offices and display rooms in
New York City. Philadelphia. Chica-
20. Boston. Detroit, San Francisco
and Kansas City. The sales engi-
neers at these offices look after the
Ritter equipment used in their re-
speetive districts in addition to TAX
ing charge Of installations and doing
general cooperative and educational
work in the profession. II may be
truly said now that the Ritter ser
vice organizations cover this eoun-
try and foreign fields are also being
capably cared for.
The employees Of the Ritter plant
are highly skilled artisans and seem
to the visitor TO constitute a most
happy industrial family. They are
very proud Of their product. The
company is just completing a new
plant hospital which will be one Of
the best Of its kind in the city.
