International Projectionist is not responsible for personal opinions appearing in signed articles in its columns. 420 Monthly Chat MOTION pictures are being used extensively in the Armed Forces for training purposes. We have all heard rumors of more than one type of training being aided by films. Just recently, however, a new training device was put into production. While no details are at present available, this device is understood to be extremely important and to require the most precise synchronization for proper functioning. Such precision has never been approached in synchronizing sight and sound in the theatre. The control track principle developed just prior to the War, required more exact recording and reproducing than the then standard single-track film, but even that takes a back seat to what is being done for the prosecution of the War. These technical advances will not be allowed to lapse after the War, but will form the basis for new and probably startling developments in the art. The entertainment value of motion pictures will be increased and there will be a much greater appreciation of their value for educational purposes. In the past, several plans had been made to introduce films into the educational program, but progress was slow. With the impetus given by the success of the current methods in use in the various branches of the service, we may expect these plans to materialize. The Federal Treasury is offering this year to people whose 1943 income was $3,000 or less, a simplified income tax form, known as Form 1040-A, which can be filled out in five minutes or less. It may be used by any taxpayer whose $3,000-or-less income came wholly from wages, salaries, dividends, interest and annuities. With the simplified Form 1040-A there are but six things for the taxpayer to do: (1) write down name, address and occupation; (2) list your dependents; (3) state amount of income received during the year ; (4) subtract your credit for dependents; (5) indicate your family status (whether married, single, etc.), and (6) show the amount of tax to be paid, which can be found by reading the table on the tax form. People whose legal deductions are unusually large would probably pay less tax by using the longer Form 1040, but for most people in the $3,000-and-under bracket, Form 1040-A is not only a timesaver, but a money-saver. Either of these forms may be obtained from your employer or your local Internal Revenue Office. We suggest to our readers that they file their returns as early as possible, and not to wait for the March 15 deadline. In this way they will not only be helping themselves, but they will be making a real contribution to the smooth working of the nation's tax machinery. FEBRUARY 1943
