The Debrie D.I 6
Operators using this machine for the first time will get two very pleasant surprises — the excellent reproduction of sound, and the unusual quietness of the mechanism.
The D.16 is manufactured in Britain by Cinetechnic Ltd. The Company's claim that the machine is precision-engineered is a very modest one, for the new specially designed mechanism is so quiet in operation that it is hardly audible above the gentle hum from the motor; thus obviating any necessity for a blimp, and allowing the projector to be used in close proximity to the audience without distracting their attention.
Compared to some projectors, the new Debrie appears at first glance to be something prepared for the novice, but a second look is quite sufficient to make us quickly revise this opinion.
The machine is constructed from self-contained units all of which can readily be removed for inspection or servicing;
The "gentle hum" we mentioned comes from a new type 1/15 h.p. constant-speed motor, which is set within a shock-proof coupling at the rear of the lamphouse. It is so designed that you can take it out and dust it whenever you feel like it, a job which only takes a few seconds.
A convenient switch allows a 750-watt lamp (for example) to be operated at a lower voltage to equal the brilliance of a 500-watt lamp, thus lengthening the life of the former. A powerful blower-type fan provides adequate cooling within the lamphouse, and an unusual feature is that the lamp cannot be switched on unless the fan is working, thus minimising a form of film damage.
The intermittent movement consists of a new smooth-action triple claw perfectly synchronised with the single-bladed shutter — the latter so made that it requires no adjustment by the operator. A steady picture is ensured by correctly balanced pressure rails within the gate, the latter made to swing out through 90 degrees for easy cleaning and rapid servicing. Other contributory factors to the quiet running of the projector are the shaft-driven
