Year book of motion pictures (1929)

sists almost entirely of a classification of patents claiming methods of producing stereoscopic motion pictures. In a short introduction, the author discusses the subject briefly and explains the classification which he uses in the presentation of his patents and patent abstracts: (88). Studios and Studio Practice Hardly a corner on earth exists which cannot be reproduced on the motion picture lot. Photographs of the real site of a play are taken and a duplicate can nearly always be found near Hollywood: (89). The Muto Studio, Lankwitz, measures 35x20 meters. Originally built as a daylight studio, it has had much of the glass roof and sides colored blue. The transformers for serving the lights have a combined delivery of 465 kw: (90). The blue glass, used by many cameramen in arranging lighting, is of questionable value: (91). In an attempt to simplify studio lighting problems a German adjustable light standard, six meters high, has been recommended: (92). Two Zeppelin hangars at Staaken have been converted into motion picture studios. The larger hangar, 48 meters by 250 meters, contains two studios, and the smaller, 35 meters by 230 meters, contains four. Both studios are furnished with modern equipment, including a great variety of lamps: (93). An article on "Printing Motion Picture Film," describes different types of printing machines including those of the continuous, step-by-step, and projection types. Considerable space is devoted to the automatic light change mechanisms. A description is given of a suitable motor generator set for exact voltage control. A sensitometer for the determination of correct exposure time is illustrated and its use in obtaining "key tests" described: (94). Talking Motion Pictures A new talking motion picture device — the Kinegraphone (General Electric) has been successfully demonstrated. This apparatus is very simple in operation, requiring only a slight change in present standard projectors. No change is necessary in the technic of making the film. After the original film is made and titled, the accompanying music may be recorded on it: (95). General Electric Co., Radio Corporation of America, and Westinghouse have purchased an interest in F B O and will market the Kinegraphone through it: (96). Equipment to display "Movietone" subjects is being installed in many theaters: (97). The General Electric Co. is producing soundreproducing equipment on a large scale as a result of the purchase by General Electric, Westinghouse, and Radio Corporation of America of an interest in F B O : (98). In the "Movietone" an amplified current from a microphone goes to a helium lamp. The variations in intensity are used to give a strip of variable density along the side of the picture on the film: (99). A method of reducing sonorousness is described as consisting of several sound records of the same subject reproduced very slightly out of phase: (100). In one talking motion picture system perfect synchronism of a phonograph record and a motion picture is maintained by means of a gear so arranged that the phonograph controls the projector. Fluctuations in speed are automatically adjusted and the machine automatically stops in case of film breakage: (101). Television It is predicted that eminent scientific authorities may soon lecture to many audiences at the same time, illustrating their addresses with motion pictures, through a hook-up between the radio and the movies: (102). It has been claimed that the Atlantic has been spanned by Television.
