within a baffle case, and a number of other things, but all of which will make the cost of the conversion very similar to the initial cost of your projector. If you originally paid about £60 for the projector you can expect to pay another £60 for the pleasure of hearing it produce sound. Advertisements in the cine trade press will give you the names and addresses of the firms specialising in this work.
Q. I have recently taken delivery of a 16 mm. projector fitted with a 2" lens, which I have to instal in a building 45 feet long. What size screen do I require ?
A. You will need a screen exactly 8' 5" wide for a throw of 45 feet, but having regard to the fact that setting-up the projector will actually cause your lens to be four or five feet from the back wall you should reckon on a throw of about 40' instead of 45'. The width of the screen should therefore be approximately 7' 6". (See table on p. 79).
Q. Where can I exchange my 17.5-mm. projector for one using the 16-mm. gauge}
A. Through a cine dealer — look for one who advertises cine sales and exchange. Very few people will want to make such an exchange with you, however, and I suggest that you have the gauge converted. This will cost an amount perhaps equal to what you would probably lose were you to effect the exchange you contemplate!
Q. I find it necessary to purchase a 3" lens for my 16-mm. projector. Is there any particular make you would recommend!
A. Yes, the one recommended by the manufacturer of your projector. When giving your order state the make and model of the projector, i.e., G.B. model H.16. The fact that you require a 3" lens indicates that it is to be used for a fairly large audience, and I advise you to ask for a ' 'bloomed' ' one. This means that the lens has been surface-treated to ensure added brilliance and better definition.
Q. I have just bought a small projector for use at home. It has an A.C. /D.C. motor and I thought this would be all right to use on the D.C. mains in my district, but now I find that the motor is rated for no volts only and that I shall have to get a transformer. Can you tell me ivhere I can get one and exactly what I should ask fori
A. You appear to be asking for f rouble. A transformer must
