Title: Improvements in or relating to stereoscopic motion picture systems
IPC: G03B35/24
Filed: 1930-02-07
Abstract: 348,118. Stereoscopic kinematography. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Ives, H. E. ; 32, Laurel Place, Montclair, New Jersey, U.S.A.) Feb. 7, 1930, No. 4222. Convention date, Feb. 9, 1929. [Class 97 (i).] Stereoscopic motion pictures which do not necessitate the use of auxiliary apparatus at the observer's eye are produced by taking a number of series of images from different view points, projecting these images simultaneously on a screen through means for breaking up each image into a series of line elements, and viewing the projected image through a selecting device so that each eye receives light from one series of line elements only. The original images may be taken by a number of kinematograph cameras, e.g. 50, arranged on the arc of a circle and operated in synchronism, the cameras being narrow so that the lenses are practically juxtaposed, or the cameras may be used in pairs, half the number being employed and a rotating plate of glass 20, Fig. 3, being used to deflect the images from different view points alternately into the camera, or fewer cameras may be used, each camera being stepped into a succession of different positions between exposures. For projecting the images a corresponding number of projectors 85, Fig. 8, may be used, directed towards a screen 86, a grating of opaque and transparent lines 87 being interposed between the screen and the projectors and a similar grating 88 between the screen and the observers. Alternatively the image on the screen 86 may be rephotographed without the grating 88 and the resulting film projected through a similar grating. Or the images may be copied on a single film and projected by a rapid projector the grating 88 being in this case moved into a series of positions corresponding to the view points of the taking cameras. In a further modification, Figs. 12 and 15, the image is taken on a film 120 through a grating 121, by a lens 125 arranged in front of a slit 124 in a rotating disc which moves across a cylindrical lens 122 which thus acts as a prism of constantly varying angle. Projection is effected through a similar arrangement Fig. 15, gratings 158, 159 being arranged on each side of the screen as before.

Filed: 1920-02-13
Abstract: 162,432. Edwards, T. J. Feb. 13, 1920. No Patent granted (Sealing fee not paid). Mechanical toys.-A mechanical toy representing a boxer has legs rigidly attached to a body carrying a swinging head, and the arms are moved alternately to deliver swinging blows, thereby causing the figure to shuffle along the surface on which it is placed. A wire ring or a guide-rod is used to restrict the movement of the figures. The body A is rigidly attached to the legs B, while the head is loosely supported on a collar plate E so as to swing forwards and backwards. One of the arms G, is bent and is oscillated laterally by means of an escapement I driven by clockwork R. The other arm G<x> is oscillated in a vertical plane, to deliver an " upper out " by a cranked spindle Tx driven by the clockwork. The swing of the arms causes the figure to shuffle forwards slowly, and by placing two figures near to one another, they can be made to imitate boxers. The fists U of the figure are secured to a rod U<x>, Fig. 5, which can be pressed into the hollow arm against the action of a spring V, and retained by a lug U<1> which engages in a slot G'. Thus when the fist of one figure strikes any part of the other figure, the catch U<1> is released and the spring V shoots the fist forwards and strikes a blow. The figures may be placed within a wire ring, or astride a guide-rod, to prevent them from wandering away from one another.
