Abstract: The present invention is an inflatable barrier device for use with elevator door jamb panels and entryway doors and jambs to protect the surfaces of these panels and doors from sustaining damage from collisions with moving equipment, building materials and furniture. The device protects the surfaces from scratches and dents when furniture and construction materials inadvertently bang into these protected surfaces. The entryway protector comprises two sections and securing components. An inflatable main rectangular section is separated by a line of stitching from a minor rectangular section or flap that is filled with padding material. The securing components secure the protector to the surfaces against dislodging by contact with equipment, building materials and furniture.

Abstract: A method for high-speed and simultaneous printing of a number of 3-D photographs by utilizing a printer with a wide field of coverage so that all of the 2-D views required to produce a 3-D photograph are projected simultaneously onto the number of 3-D photographs corresponding to the number of 2-D negatives utilized. All of the 3-D print materials advance to the next position for printing until all of the image bands are filled with a portion of the appropriate 2-D view. A high speed printer with a wide field of coverage capable of simultaneously projecting all of the 2-D views required to produce a 3-D picture onto a number of 3-D prints which may have a computer or microprocessor controlling the exposure and moving the 3-D print material between exposures.

Abstract: A method for determining the spacing between adjacent vantage points for taking a 3-D photograph which involves computing the desired spatial parallax in accordance with the following formula: ##EQU1## where P is the desired spatial parallax, V is the viewing distance and E is the capability of the eyes to fuse the two images together expressed in terms of arc minutes of the scanning angle and utilizing results of this computation to compute the distance T between adjacent vantage points in accordance with the following formula: ##EQU2## where B is the distance between the camera and the background object and K is the distance between the camera and the key subject and u is the back focal length of the camera lens. A calculator has been provided for making the necessary calculations.

Abstract: The method of checking the off-alignment and identifying the relative position of lenses in a multi-lens, 3-D camera and calibrating the coordinates of the positions of the components (i.e., 2-D view, projecting lens or print material easel) of a printing system. The method for the automatic correlation of 2-D views for the composing of high quality 3-D photographs by taking the first set of 2-D photographs on the film of a target at a predetermined distance. The target images are projected onto a group of CCD sensor arrays placed at the image plane of the printer with each individual sensor of the CCD array precalibrated, and a computer on the printer is programmed to recognize the location of the target images on the CCD array and to control the motors on the printer to adjust the position of the enlarging lens, the easel or the 2-D view in order to correlate the 2-D views for the aligning of the photographed image on the print material at the time of composing of the 3-D photograph.

Abstract: A method and apparatus for achieving uniform density of image elements of a 3-D photograph by using a 3-D printer with a linear motion blade shutter which travels at varying speeds during printing a negative view to control the duration of exposure across the 3-D photograph. The scanning speed of the linear shutter is varied during the exposure of each of the 2-D negative views and is based upon the position of the 2-D negative view in relation to the field of illumination of the enlarging lens in order to compensate for the non-uniformity of illumination due to the vignetting effect.

Abstract: A method and a printer for printing an image array on the photosensitive surface of lenticular print film from a set of 2D views which involves moving the negative carrier on the printer in accordance with the equation ##EQU1## where S is the distance between key subject images of adjacent 2D views,T is the separation between adjacent camera lenses,F is the back focal length of the camera lens,K is the distance between the lens of the camera and the key subject K' and moving the negative by the appropriate S value between printing of adjacent 2D views.A fully automatic and semi-automatic printer is provided.

Abstract: Three-dimensional photographs produced with image bands of substantially equal density across the field of the lenticule are produced by increasing the intensity of exposure of the image bands near the edges of the lenticule in relation to the central image bands. This is accomplished by varying the duration of each exposure, or using a neutral density filter, a neutral density iris, a metallic iris with a multiple number of apertures, or by controlling the lamps in a multiple lamp housing. In addition, three-dimensional photographs are produced by a multiple number of successive exposures of short duration through the lenticules of the lenticular print film while the angle of projection of the enlarging lens is constantly changing. Exposure is made for a duration while the relative movement of the enlarging lens with respect to the lenticular print film is less than one-tenth of the aperture of the enlarging lens.

Abstract: Three-dimensional photographs are produced in which there are three image bands within each lenticule in which each image band is between 8.5 degrees and 11 degrees in width in order to permit a photograph to be viewed from wider angles so that the eyes will see adjacent stereo pairs from any viewing angle and the picture will be in total focus. A three lens camera is provided to take these photographs.

Abstract: A carton in which a plurality of containers (C) are held in a complementary set of apertures (A) provided in a main panel (16) of the carton so that portions of the containers are exposed to view while other portions are enclosed by other panels (30,32; 14,18; 12,20) of the carton. An opposed pair (30,32) of these other panels for flanking body portions of the packaged containers include positioning tabs (38,40; 42,44) which extend into the container receiving apertures so that during loading and formation of the package the containers are urged against the positioning tabs which automatically cause the flanking panels to be pivoted into and held in the container flanking position.

Abstract: An elongated plastic track for use in a gravity feed display is extruded from a mixture of high impact polystyrene and dimethylpolysiloxane.

Abstract: A continuous process for removing sulfur dioxide from flue gas by reacting sodium aluminate solution with sulfur dioxide to form sodium sulfite and aluminum hydroxy sulfite which are separated and the aluminum hydroxy sulfite oxidized to aluminum sulfate.

Abstract: A lifting dollie is provided for moving paper rolls, featuring a U shaped frame supported by castor wheels, with a pair of lifting arms which are attached to the ends of a pivot tube extending through a tubular rear frame member with a square cross-section. A hydraulic pump and ram is used to raise the lifting arm. A chain driven steering mechanism is utilized for the remote steering of one of the rear castor wheels.
