118 ABSTRACTS [J. S. M. p. E. for framing and this plate is resiliency mounted on a second supporting plate carrying the objective. 1,777,419. O. A. Ross. Focus and finding apparatus for motion picture cameras. This camera is equipped with an optical system reflecting and focusing an image from the objective upon a viewing screen intermittently, and in timed relation to taking pictures. Thus an operator can view action through the finder and focus it at the same time. 1,799,653. E. N. BALL. A sound insulated camera is made by building up sound proof walls around parts of the camera and film reels. The sound proof walls are provided with suitable doors to give access to necessary camera parts, and with a window to see through the walls. The housing is built up from a tripod head and particularly guards a sound recording chamber from the noise of the camera mechanism. 1,776,049. E. I. SPONABLE. This patent relates to the splicing of sound records. To overcome the unpleasant sudden change of sound records where films are spliced together a small diamond or arcuate shaped aperture may be cut from the film through the spliced sound record. This leaves all but a narrow portion of the splice intact so that it does not materially weaken the splice. 1,781,053. R. E. DEBAULE. Illuminating system. This system includes a lamp and reflector assembly. An incandescent lamp is illustrated as having the filaments to one side of the center of the bulb, which may be mounted between two adjustable, spaced reflectors, one in front of the lamp and the other behind the lamp. Condensing lenses are supported in brackets extending through a central aperture in the front reflector and are in axial alignment with the filaments of the lamp. The lamp and reflector supports permit accurate focusing. ' 1,777,682. E. I. SPONABLE. Combined sound and motion picture camera. To dampen mechanical impulses in a camera for taking sound and picture records a yielding guiding connection is provided between the film sprocket and the shutter shaft. This guide may include a plurality of springs, each having one end connected to a flywheel, and each having the other end connected to one of a series of radial posts carried by a rotating member so that the drive is through the plurality of springs. 1,777,828. LEE DEFOREST. For sound and picture photography this patent proposes the use of two cameras, one for the sound record and the other for the picture record. Each of these cameras may be driven by a synchronous motor so that the sound and picture records may be made simultaneously with the cameras which may be spaced at different distances from the scene. These records may then be printed on a single film, using the desired portion of each film for a completed sound and picture record. 1,780,585. A. FRIED. A camera support permitting a camera to be mounted thereon and arranged to facilitate turning the camera on a horizontal and on a vertical axis. To insure smoothness and freedom from "chatter," a gear train is arranged to govern the movement about each axis. Each gear train terminates in a relatively heavy flywheel which limits the speed of the turning or panoraming movement. A handle projects to one side of the device for controlling the desired camera movement. 1,781,501. E. O. ORD. An optical system for use with camera objectives for producing humorous effects. Pairs of prisms are spaced angularly with respect
