Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides a method for recovering vanadium, niobium, tantalum and zirconium from vanadiferous residues arising from the chlorina-tion of titaniferous ores. Such residues contain chlorides of these metals and/or titanium, aluminum, iron, chromium and manganese together with carbon and unreacted titaniferous ore. The method comprises first moistening these residues with water and then treating them with hot water for sufficient period of time to extract substantially all the vanadium into solution which is separated from insoluble material comprising carbon and unreacted titaniferous ore together with substantially all the niobium, tantalum and zirconium.

Abstract: ABSTRACT OF THE DISCLOSURE A roof structure is formed with a plurality of sub-stantially parallel purlins mounted on rafters, with each purlin  including a central web and a laterally extending upper flange.  The upper flange of each purlin defines a plurality of equally spaced openings therethrough, and layers of insulation material are applied to the upper and lower surfaces of the upper flange.  Sheets of hard roofing material are mounted on the purlins and fasteners are inserted through the sheets of roofing material and extend down through the openings in the upper flanges of the purlins and through the layers of insulation material so that the sheets of roofing material and fasteners are isolated by the insulation material from the purlins.  Additional insulation material is located between adjacent ones of the purlins below the sheets of hard roofing material.

Abstract: ABSTRACT     My invention relates to photographing scenes with standard motion picture photographic equipment in which there is a relative motion between the scene and camera with the purpose of stereoscopic viewing of the motion picture or stationary reproduction without the need for viewing aids at the eyes. The system is compatible with scenes photo-graphed without this relative motion, where with the repro-duction is viewed in conventional two dimensions.     The surface of the processed film (or other appropriate media) is arrayed in a vertical plane and constrained to move horizontally around a segment of a circle of radius 2R.          At the center of the film circle is a film motion compen-sator which can be a multifaceted mirror drum of radius R.     The film is rapidly scanned about the center of this circle by a light source directed through the film and toward the center of the mirror drum.  The optical film scanner contains projection optics on the inside of the film circle that rotates the bright central image at the mirror drum center-line by a fixed 90 degrees and develops a horizontally scan-ning and circularly moving pseudo projection point to pro-vide a suitably large and erect picture format on a semi-specular and circular viewing screen having both horizontal and vertical elements.  The rotating pseudo projection point scans and repeats at a rate to exceed the flicker frequency of the eye.  The horizontal elemental screen charac-teristics cause the projected rays to vertically diffuse.          The vertical elemental screen characteristics cause the reflections of the sweeping central projections ray to re-main parallel as it leaves the screen toward the observer's eyes.  The vertical elements also cause the whole images projected by the pseudo projection point, to converge at the vertical pseudo slit position.  The angular velocity of the pseudo slit is equal to the angular velocity of the scanning pseudo projection point.  An alternate semi-specular curved screen is constructed with horizontal ridges over the whole screen width to cause vertical diffusion of the pro-jected light and to develop the circularly moving pseudo vertical viewing slit.  If the film and motion compensator remain stationary, the stereoscopically reproduced scene is also stationary.  If the film and motion compensator are in locked motion as the film is scanned by the optic scanner, the picture will move and stereoscopic motion pictures can be observed without any form of visual aid at the observer's eyes.

Abstract: Abstract of the Disclosure A bidirectional optical fiber transmission system is disclosed. Two transmitter-receiver sets are interconnected by an optical fiber and each set includes a light emitting diode (l.e.d.) transmitter, a light receiver and circuitry for mutually isolating transmitted and received light.  The emission spectra of the l.e.d.'s should be identical or overlapping and the isolating circuitry in each set comprises a short wave pass filter and a non-overlapping long wave pass filter.  An optical directional coupler or light divider is used to couple the transmitting and receiving sides to the optical fiber.

A portion of the platform serves as a cam follower. A cam member is rotatably mounted on the housing adjacent to the fulcrum and positioned so as to be capable of interacting with that portion of the platform serving as a cam follower.  In response to rotation of the cam the platform, including the maze located thereon, is tilted.  An object located within the maze is capable of moving within the maze in response to tilting of the platform.

Abstract: Title of the Invention :-Ball Valve Assembly Abstract of the Invention :-The invention relates to a ball valve assembly including a ball valve member made of a plastic resin material, preferably polyvinyl chloride, and movable mounted in a valve cavity formed in a valve body again made of a plastic resin material, preferably polyvinyl chloride. In the assembly, the valve body consists of two body elements coupled in a male-and-female connection with each other and rigidly and permanently united together thereat. Thus, the ball valve is confined in the valve cavity in an unseparable way, and yet kept nearly in a floating condition within the valve cavity by direct and resilient contact with a pair of seat rings made of an elastomer or elastic rubber.      These seat rings are so shaped and arranged when seen in an axial section of the valve assembly that they represent four limited contacting areas with the ball valve exerting sealing and floating pressures against the ball valve directing all substantially towards the center of the latter.

Abstract: BUBBLE OXYGENATOR     ABSTRACT OF THE DISCLOSURE  The oxygenator is used for arterializing blood during open heart surgery.  The oxygenator is factory-assembled and sterilized and is of economic and efficient design so that it can serve as a throwaway unit.  Blood from the patient is oxygenated as it passes through the center of a tubular sparger with porous walls which supplies oxygen bubbles of the optimum size.  The foaming blood is delivered to the top of the main oxygenator body where it is distributed by gravity flow downward across the heat exchanger tubing.  The heat exchanger is wound as a flat coil with all connections outside of the oxygenator body.  A silicone-coated sponge is located below the heat exchanger so that downwardly flowing foaming blood is defoamed as it passes through the sponge.  Carbon dioxide and other gases are vented, and liquid blood gravitates into a tapered arterial reservoir.

Abstract: Abstract of the Invention A video signal image reproducing system including a video signal processing channel, a kinescope driver for supplying amplified video signals to an image reproducing kinescope, a source of potential to which signals processed by the kinescope driver are referenced, and an adjustable brightness control network which provides a range of brightness reference voltages including a given voltage corresponding to a threshold conduction condition of the kinescope driver.  The brightness network is biased from a voltage source from which the signal reference potential is derived.  The signal reference potential is coupled to the kinescope driver, and to the brightness network such that the given voltage is produced when the brightness control is at a mid-range setting.  A comparator compares a brightness reference voltage from the brightness control with a periodic blanking level of the video signal to provide an output control voltage, which is applied to the video channel for translating the blanking level in a direction to minimize the difference between the compared signals.
