The motion picture projectionist (Nov 1931-Jan 1933)

32 Motion Picture Projectionist December, 1931 Television-Talkiola A NEW Television Talkiola ma**■ chine, which is claimed as being the most complete home entertainment device ever produced, was exhibited recently. It is made especially for home use and incorporates within the one machine six different types of entertainment. These include television with synchronized sound, talking motion pictures, silent pictures, electric phonograph, short wave radio and standard broadcast radio. All mechanisms are concealed within a handsome walnut cabinet, not very much larger than the consoles used to house the better types of radio receivers. The Television-Talkiola cabinet is extremely attractive in design and will help to adorn the most luxuriously appointed home. The Television Equipment The television unit for viewing the radio-transmitted picture is located at the top of the cabinet. It includes a l/15th horsepower synchronous motor which turns a horizontal metal plate. The plate supports a narrow strip of thin steel perforated with a number of square holes. The plate also supports a neon lamp. There is an adjustable lens at the front of the cabinet, set within a specially designed visor. The adjustment permits the television picture to be focused as required. The 6"x8" picture is very clear and the special visor prevents extraneous light from dimming the image. Below the visor are knobs for turning the current "on" or "off" and for keeping the picture in frame. Other Details Below the television unit is the phonograph with electrically operated turntable and electromagnetic pickup. Underneath this is the motion picture projector, designed for 16 millimeter film. A l/20th horsepower electric motor is used to drive both the phonograph turntable and the motion picture projector. Perfect picture reproduction is attained on a transparent screen which unfolds from the front of the cabinet, allowing a large number of people to view the picture. A standard radio tuner of ultra-modern design occupies the space below the projector. A separate and complete short wave receiver for tuning in television signals is located within the cabinet, with controls and tuning dial on the right side of the cabinet. The Amplifier The cabinet also contains a powerful two-stage amplifier, with a 124 screen grid tube in the first stage directly coupled to two 145 power tubes arranged in push-pull in the output stage. The dynamic reproducer is located at the lower left portion of the cabinet. This speaker is of the highest quality obtainable. In the lower right-hand portion of the cabinet there is a large compartment for films and records. The dynamic speaker is removable in order that the sound may be projected from any portion of the room, as desired. It is a product of the Talkiola Corporation of New York. Mr. Herschman, sales manager for the company, states that the firm is doing an excellent business not only in photocells, but also in television products such as crater tubes and cathode ray tubes. New Telephoto Cell According to a recent announcement of the Telephoto & Television Corporation of New York, its research group has recently developed a new photoelectric cell of great sensitivity. The new tube is of the caesium argon type and carries a six months' guarantee, it is stated in the company's announcement. The cell is manufactured in three sizes and is fitted with the standard four-prong base. The polarizing voltage range is from 22% to 90. With 90 volts on the plate, the output of the cell is rated at approximately 50 micro-amperes per lumen. New Filmo Projector ANEW Filmo projector, the Model J, is announced by Bell & Howell. With a picture brilliance asserted to be practically 30% greater than that afforded by even the Filmo 57-GG, it is hailed by its makers as marking "the most outstanding advance in the history of personal movie projection." Life-size movies of theatre quality, it is stated, are easily projected by it in the home, classroom, or auditorium. For months, we are informed, engineers have been engaged in perfecting this new projector. Not only are superlative performance and ease of operation claimed for it, but it has a handsome, luxurious appearance and sets a high mark in beauty of line and finish. The Model J is low-built with a large base designed to afford desirable stability, as well as making for beautiful proportions. The new projector is entirely geardriven and hence dispenses with all belts and chains. The gears are fully encased. This is asserted to be the first fully gear-driven 16 mm. projector. The notable increase in picture brilliance, which is said to have been demonstrated in exhaustive tests, has been secured by an improved 375 watt lamp, a new Cook 2-inch F 1.5 projection lens, improved condenser, a large reflector, and a refined reflector adjustment. And there is a novel light trap whose purpose is to prevent the escape of stray illumination. The above are only a few of the new and distinctive features of this new projector which, the manufacturers state, is bound to be a sensation in the 16 mm. world.
